Ltd. (Tokyo, Japan). It was reported to have epoxy cure site and was made from ethyl acrylate monomer. Tetraethoxysilane (TEOS, density = 930 kg/m3) was procured from Acros Organics (USA). Tetrahydrofuran (THF, 99% pure) was purchased from Merck (India). The precipitated silica (Ultrasil VN3, particle size range = 40-100 nm, oil absorption = 2.4 g/kg, pH = 6) was supplied by Bayer AG (Germany). Benzoyl peroxide (BPO, 97% purity) was purchased from Aldrich Chemicals (USA). Hexamethylenediamine carbamate (HMDC, DIAK#1) was supplied by Nicco Corp. Ltd. (India). Ammonium benzoate (AmBz) was prepared in the laboratory by reacting ammonium hydroxide and benzoic acid in 1:1 molar ratio in a water bath at around 60degC for 30 min. The salt formation was confirmed by Fourier transform infrared spectroscopy as well as by studying its solubility. Deionized water and concentrated hydrochloric acid of laboratory grade were obtained from indigenous sources. \nThe desired amount of ACM was dissolved in THF solvent. A proportion of the rubber to solvent was maintained at about 1 : 10 all throughout the experiment to retain the uniform viscosity of the reaction medium. TEOS, deionized water, and concentrated HCl as catalyst, in the molar ratio of 1 : 2 : 0.06,15 were throughly mixed by vigorous stirring for 15 min and then the mixture was added to the rubber solution under stirring conditions at ambient temperature. The proportion of TEOS was from 0 to 50 wt % of the ACM. Beyond 50 wt % TEOS, macrophase separation occurred. The formulations used in this study are given in Table I. The precursor solution for preparing the composites was stirred for 30 min and then poured over a uniform and thoroughly cleaned glass plate. The initial evaporation of the solvent was carried out under controlled conditions for 24 h, and then, in the next phase, further evaporation for 4 days was allowed to remove the residual solvent and byproducts (water and ethanol). The optimum gelling time was taken when practically no weight variation of the hybrid composites was noticed. All the films were transparent in appearance. For comparison, composites were also prepared with precipitated silica up to 30 wt % of its loading (beyond which the resultant film lost its homogeneity). The precipitated silica was initially dried at 120degC for 24 h and then dispersed in the ACM solution. All the composite films with precipitated silica were opaque and completely white in color. To crosslink the rubber phase, curatives were added to the solvated rubber. The two different curatives systems used in this study were BPO and a mixed crosslinked system comprising AmBz and HMDC, following an earlier work on acrylic rubber in our laboratory.16 Optimization of the doses of different curatives (Table I) was carried out by studying the maximum gel content in THF. \nAddition of curatives was made only after complete mixing of TEOS, water, and HCl with solvated ACM for 30 min. The crosslinkers were dispersed under ambient conditions and then stirred for another 30 min for homogenous mixing. The films were cast over a plain glass plate as before and kept for controlled solvent evaporation for 24 h. In the next phase, peroxide-containing composite films were kept in the oven at 70degC for 2 h for curing, whereas the samples having mixed crosslinked system were cured at 170degC for 30 min. The above cure times were optimized from the maximum gel content values.", "measurement_extractions": [ { "quantity": "ML1+4 at 100degC = 51", "unit": "ML1+4 at 100degC", "measured_entity": "Acrylic rubber", "measured_property": "Mooney viscosity" }, { "quantity": "1100 kg/cm3", "unit": "kg/cm3", "measured_entity": "Acrylic rubber (ACM", "measured_property": "density" }, { "quantity": "930 kg/m3", "unit": "kg/m3", "measured_entity": "Tetraethoxysilane (TEOS", "measured_property": "density" }, { "quantity": "99%", "unit": "%", "measured_entity": "Tetrahydrofuran (THF", "measured_property": "pure" }, { "quantity": "40-100 nm", "unit": "nm", "measured_entity": "precipitated silica (Ultrasil VN3", "measured_property": "particle size range" }, { "quantity": "2.4 g/kg", "unit": "g/kg", "measured_entity": "precipitated silica (Ultrasil VN3", "measured_property": "oil absorption" }, { "quantity": "6", "unit": null, "measured_entity": "precipitated silica (Ultrasil VN3", "measured_property": "pH" }, { "quantity": "97%", "unit": "%", "measured_entity": "Benzoyl peroxide (BPO", "measured_property": "purity" }, { "quantity": "1:1", "unit": null, "measured_entity": "ammonium hydroxide and benzoic acid", "measured_property": "molar ratio" }, { "quantity": "60degC", "unit": "degC", "measured_entity": "ammonium hydroxide and benzoic acid", "measured_property": "reacting" }, { "quantity": "30 min", "unit": "min", "measured_entity": "ammonium hydroxide and benzoic acid", "measured_property": "reacting" }, { "quantity": "1 : 10", "unit": null, "measured_entity": "rubber to solvent", "measured_property": "proportion" }, { "quantity": "1 : 2 : 0.06", "unit": null, "measured_entity": "TEOS, deionized water, and concentrated HCl as catalyst", "measured_property": "molar ratio" }, { "quantity": "15 min", "unit": "min", "measured_entity": "TEOS, deionized water, and concentrated HCl as catalyst", "measured_property": "vigorous stirring" }, { "quantity": "0 to 50 wt %", "unit": "wt %", "measured_entity": "ACM", "measured_property": "proportion of TEOS" }, { "quantity": "Beyond 50 wt %", "unit": "wt %", "measured_entity": "TEOS", "measured_property": null }, { "quantity": "30 min", "unit": "min", "measured_entity": "precursor solution", "measured_property": "stirred" }, { "quantity": "24 h", "unit": "h", "measured_entity": "solvent", "measured_property": "evaporation" }, { "quantity": "4 days", "unit": "days", "measured_entity": "solvent", "measured_property": "evaporation" }, { "quantity": "up to 30 wt %", "unit": "wt %", "measured_entity": "precipitated silica", "measured_property": "loading" }, { "quantity": "120degC", "unit": "degC", "measured_entity": "precipitated silica", "measured_property": "dried" }, { "quantity": "24 h", "unit": "h", "measured_entity": "precipitated silica", "measured_property": "dried" }, { "quantity": "30 min", "unit": "min", "measured_entity": "TEOS, water, and HCl", "measured_property": "complete mixing" }, { "quantity": "30 min", "unit": "min", "measured_entity": "crosslinkers", "measured_property": "stirred" }, { "quantity": "24 h", "unit": "h", "measured_entity": "films", "measured_property": "controlled solvent evaporation" }, { "quantity": "70degC", "unit": "degC", "measured_entity": "peroxide-containing composite films", "measured_property": "kept" }, { "quantity": "2 h", "unit": "h", "measured_entity": "peroxide-containing composite films", "measured_property": "kept" }, { "quantity": "170degC", "unit": "degC", "measured_entity": "samples", "measured_property": "cured" }, { "quantity": "30 min", "unit": "min", "measured_entity": "samples", "measured_property": "cured" } ], "split": "train", "docId": "101002app20681", "dataset": "msp" }, { "instruction": "\n You are an expert at extracting quantity, units and their related context from text. \n Given a paragraph below identify each quantity and its related unit and related context, i.e. the measured entity and measured property if they exist.\n ", "paragraph": "10.1002/app.40112\nComparison of the effects of phenyl dichlorophosphate modified and unmodified \u03b2-iron(III) oxide hydroxide on the thermal, combustion, and mechanical properties of ethylene-vinyl acetate/magnesium hydroxide composites\nPhenyl dichlorophosphate (PDCP), iron(III) chloride hexahydrate (FeCl3*6H2O), and tetrahydrofuran were purchased from Sinopharm Chemical Reagent Co., Ltd.

Zn(NO3)2 (1 mmol) dissolved in 100 mL of distilled water with continuous stirring. NaOH solution was added into the drop by drop until the pH of the solution became 12. The resulting white particles were washed three times with distilled water and dried for 24 h at 80 degC. At this point, the white product did not show high crystallinity since it consisted of ZnO and Zn(OH)2. Calcining at 500 degC for 1 h was necessary to obtain high crystalline ZnO [30]. \nSynthesis of CuxZn1-xO (1% Cu-doped) nanopowder was carried out using a modified procedure [23] and [24]. The targets were specifically designed using high purity Zn(NO3)2*6H2O (99.99%) and CuSO4*5H2O (99%) powders. The Cu-doped ZnO catalyst was prepared by a two-step procedure: (1) preparation of the precursor by co-precipitation; (2) formation of the Cu/ZnO nanopowder by thermal decomposition. This method has been considered to be efficient and inexpensive, allowing for the production of high purity, homogeneous, and fine crystalline powders. \nStoichiometric quantities of Zn and Cu salts were dissolved in 100 mL of deionized double distilled water (solution A). Separately, a solution was prepared by dissolving appropriate amounts of NaOH and Na2CO3 in deionized double distilled water (solution B). Solution A was heated to 85 degC and solution B was added dropwise into it with constant stirring.

The raw palm oil fuel ash was oven dried at 110 +- 5 degC for 24 h , sieved with a 300 \u03bcm sieve to remove large unwanted particles and incompletely combusted materials [49] and [50], and then it was ground by a modified Los Angeles machine [42]. The specific surface area after grinding was 0.915 m2/g. As can be seen, major components are SiO2 and CaO with concentrations of 47.37% and 11.83%, respectively with a low amount of Al2O3 (3.53%). The relatively high amount of CaO available in the POFA is most likely from lime and fertilizer [41]. It is worth to mention that POFA is a not toxic waste material in terms of heavy metals leachability [51]. \nSodium hydroxide and sodium silicate were chosen as alkali activators in this investigation. The sodium hydroxide was in industrial-grade with minimum 99% purity. Industrial grade water glass (Na2SiO3) solution was chosen with a chemical composition of 15.33% Na2O, 31.28% SiO2, and 53% H2O. The alkaline activator selection was based on the recommendations in [34], [53], [54] and [55]. The alkali activation solution was prepared by mixing Na2SiO3 with NaOH within ratios ranged between 0.5 and 3.0 [34]. \nPreliminary experiments were conducted to study the alkali activation of POFA [56]. It revealed that raw POFA cannot be used without sieving and grinding because of the low compressive strength results which is related to the porous structure and high demands for the alkaline activator. Experimental program was designed in order to investigate the ability of POFA to be incorporated in geopolymer technology. NaOH solution was mixed with Na2SiO3 to produce six ratios (0.5, 1.0, 1.5, 2.0, 2.5, and 3) to prepare alkaline activator solution 24 h prior to use. Ground POFA and the alkaline activator were then mixed with two solid-to-liquid ratios (1.0, 1.32) as in [34], [53], [57] and [58]. Mix one with sodium silicate to sodium hydroxide ratio (0.5) was unable to be used; the geopolymer paste had such low workability that could not be cast in molds. \nThe palm oil fuel ash was mixed directly with the alkaline activator. First the ash was discharged to the mixer pan, and then the alkaline was added and mixed for 1.0 min at a normal speed rate (gear one). Then, the mixer stopped for 10-20 s in order to scrap the un-mixed ash on the sides of the paddle and the pan, then the mixing was continued with a medium speed (gear two) for another 1.0 min in accordance to ASTM C305 [59]. All the geopolymer paste mixes were blended and produced with a small blender (HOBART Mixer). The fresh geopolymer paste was then cast into 50 x 50 x 50 mm iron molds in two layers immediately after mixing. To compact the specimen, each layer was vibrated by a vibrating table for 25-30 s. This procedure was used to remove the bubbles from the paste. After casting and vibrating, oven curing was applied directly at 60 degC for 2 h. The molds were then kept in the laboratory to reach ambient temperature. The specimens were kept in a plastic bags after de-molding to prevent any moisture loss and were stored to the date of testing [55].", "measurement_extractions": [ { "quantity": "300 \u03bcm", "unit": "\u03bcm", "measured_entity": "sieve", "measured_property": null }, { "quantity": "110 +- 5 degC", "unit": "degC", "measured_entity": "raw palm oil fuel ash", "measured_property": "dried" }, { "quantity": "24 h", "unit": "h", "measured_entity": "raw palm oil fuel ash", "measured_property": "dried" }, { "quantity": "0.915 m2/g", "unit": "m2/g", "measured_entity": "specific surface area", "measured_property": null }, { "quantity": "47.37%", "unit": "%", "measured_entity": "SiO2", "measured_property": "concentrations" }, { "quantity": "11.83%", "unit": "%", "measured_entity": "CaO", "measured_property": "concentrations" }, { "quantity": "3.53%", "unit": "%", "measured_entity": "Al2O3", "measured_property": "concentrations" }, { "quantity": "99%", "unit": "%", "measured_entity": "sodium hydroxide", "measured_property": "purity" }, { "quantity": "15.33%", "unit": "%", "measured_entity": "Na2O", "measured_property": "chemical composition" }, { "quantity": "31.28%", "unit": "%", "measured_entity": "SiO2", "measured_property": "chemical composition" }, { "quantity": "53%", "unit": "%", "measured_entity": "H2O", "measured_property": "chemical composition" }, { "quantity": "ranged between 0.5 and 3.0", "unit": null, "measured_entity": "Na2SiO3 with NaOH", "measured_property": "ratios" }, { "quantity": "0.5", "unit": null, "measured_entity": "NaOH solution was mixed with Na2SiO3", "measured_property": "ratios" }, { "quantity": "1.0", "unit": null, "measured_entity": "NaOH solution was mixed with Na2SiO3", "measured_property": "ratios" }, { "quantity": "1.5", "unit": null, "measured_entity": "NaOH solution was mixed with Na2SiO3", "measured_property": "ratios" }, { "quantity": "2.0", "unit": null, "measured_entity": "NaOH solution was mixed with Na2SiO3", "measured_property": "ratios" }, { "quantity": "2.5", "unit": null, "measured_entity": "NaOH solution was mixed with Na2SiO3", "measured_property": "ratios" }, { "quantity": "3", "unit": null, "measured_entity": "NaOH solution was mixed with Na2SiO3", "measured_property": "ratios" }, { "quantity": "24 h", "unit": "h", "measured_entity": "prepare alkaline activator solution", "measured_property": "prior" }, { "quantity": "two solid-to-liquid ratios (1.0, 1.32", "unit": null, "measured_entity": "Ground POFA and the alkaline activator", "measured_property": "solid-to-liquid ratios" }, { "quantity": "0.5", "unit": null, "measured_entity": "Mix one", "measured_property": "sodium silicate to sodium hydroxide ratio" }, { "quantity": "1.0 min", "unit": "min", "measured_entity": "alkaline", "measured_property": "mixed" }, { "quantity": "10-20 s", "unit": "s", "measured_entity": "mixer", "measured_property": "stopped" }, { "quantity": "1.0 min", "unit": "min", "measured_entity": "mixing", "measured_property": "continued" }, { "quantity": "50 x 50 x 50 mm", "unit": "mm", "measured_entity": "iron molds", "measured_property": null }, { "quantity": "25-30 s", "unit": "s", "measured_entity": "layer", "measured_property": "vibrated" }, { "quantity": "60 degC", "unit": "degC", "measured_entity": "oven curing", "measured_property": "applied directly" }, { "quantity": "2 h", "unit": "h", "measured_entity": "oven curing", "measured_property": "applied directly" } ], "split": "train", "docId": "101016jconbuildmat201405031", "dataset": "msp" }, { "instruction": "\n You are an expert at extracting quantity, units and their related context from text. \n Given a paragraph below identify each quantity and its related unit and related context, i.e. the measured entity and measured property if they exist.\n ", "paragraph": "10.1016/j.cplett.2016.08.020\nHigh catalytic activity of magnetic CuFe2O4/graphene oxide composite for the degradation of organic dyes under visible light irradiation\nCuFe2O4/GO (20 wt%) was synthesized by a hydrothermal method.

Various synthesis parameters such as calcination time and temperature as well as chelating agent are studied to determine the optimized condition for material processing. Using TG/DTA techniques, the optimized calcination temperatures are selected. Different characterization techniques such as ICP, XRD and TEM are employed to characterize the chemical composition, crystal structure, size and morphology of the powders. Micron and nano-sized powders are produced using citric/oxalic and TEA as chelating agent, respectively. Selected powders are used as cathode material to assemble batteries. Charge-discharge testing of these batteries show that the highest discharge capacity is 173 mAh g-1 at a constant current of 0.1 mA cm-2, between 3.0 and 4.2 V. This is obtained in a battery assembled with the nanopowder produced by TEA as chelating agent. The stoichiometric values of lithium, nickel and cobalt nitrate salts in a cationic ratio of Li:Ni:Co equal to 1:0.8:0.2 were dissolved in distilled water. Three chelating agents including triethanolamine (TEA), citric acid, oxalic acid are used in this investigation. These agents were used in a molar ratio of 1 with respect to the total metal cations by dissolving in distilled water. The solution was then added to the nitrate solution and was heated under constant stirring at 80 degC for 1 h. The resulting sol was heated at 100 degC to form the gel which was dried subsequently. To remove the moisture and achieve the dried mass, the obtained gel was successively dried at 100, 120, 150, 200 degC for 2 h per each step and 5 h at 240 degC. The thermal behavior of LiNi0.8Co0.2O2 powders was determined by thermogravimetric/differential thermal analysis (TG/DTA) conducted on the dried gel at a heating rate of 5 degC min-1 up to 1100 degC in the air using a Perkin Elmer analyzer. The tests were conducted in the air using alumina pans. The initial sample weights for TEA, oxalic and citric were 460, 250 and 290 mg, respectively.

The stoichiometric amount of starting materials, such as cobaltous acetate and ferric chloride were taken in 1:1, 1:2, 1:3 and 1:4 M ratios, respectively, and dissolved into required amount of distilled water to form 1 M solution. First of all, we have taken cobaltous acetate and ferric chloride in 1:1 M ratios and dissolved into respective required amount of distilled water to form precursors. The above precursors were refluxed at 60 degC for 4 h to get homogeneous solution. After that both were mixed with each other. The obtained mixed solution was heated at 70-80 degC and magnetically stirred for 4 h. 10 ml of poly-ethylene glycol (PEG) was added to the mixed solution which acts as an encapsulating agent. The resulting solution was precipitated by ammonium hydroxide solution, which was added drop by drop to the above mixed solution and a black colored precipitate was obtained. The pH of the solution was constantly monitored as the NH4OH solution was added until it reached to 12. Then the mixture was mechanically stirred at room temperature for 6 h and the precipitate was washed several times with distilled water until the pH of the filtrate became 7. Here, ammonium hydroxide was used for smooth liberation of the hydroxide ions in place of strong alkali (potassium hydroxide and sodium hydroxide). Strong alkaline solutions are prone to result in the conversion of Fe3+ and Co2+ into CoFe2O4 immediately, usually leading to the formation of severely agglomerated nanoparticles with irregular shapes. Similar procedure was used for the synthesis of nanostructured ferric oxide. \nInitially in aqueous solution, metal ions exist as Co ( H 2 O ) 6 2 + and Fe ( H 2 O ) 6 3 + . As pH was increased, the predominant species existing in solution became Co ( OH ) 6 2 - x and Fe ( OH ) y 3 - y , respectively. At the solubility minima, the predominant species in solution were Co(OH)2 and Fe(OH)3. Further, when the concentration of ammonia solution was increased, cobalt and iron became more soluble as Co ( OH ) 3 - and Fe ( OH ) 4 - species. The synthesis temperature was maintained at 70-80 degC for 4-5 h under vigorous magnetic stirring. The precipitate of CoFe2O4 was obtained through centrifugal settling for 15 min at 3000 rpm. The precipitate was dried overnight at 100 degC. The dried material was grinded into fine powder. The fine powder was then annealed at 450 degC inside a tubular furnace for 2 h with heating and cooling rate of 2 degC per minute.

Reduction was done via treating 100 mg of GO1 in 30 mL of water with 3 mL of hydrazine and refluxing at 95 degC for 24 h, followed by filtering, washing and drying at 60 degC under vacuum to obtain the rGO1 powder. \nGraphite flakes (10 g) and NaNO3 (10 g) were mixed in 600 mL of H2SO4 (98%) at 5 degC with continuous stirring for 6 h, and KMnO4 (60 g) was gradually added to the suspension while maintaining the temperature at 15 degC. The mixture was diluted with a slow addition of 400 mL of water and with stirring maintained for 2 h. The ice bath was then removed, and the mixture was stirred at 35 degC for 2 h and then refluxed at 98 degC for 30 min. The solution was finally treated with 200 ml of H2O2 and the color changed to bright yellow. The resulting mixture was washed by centrifugation with 10% HCl and then with DI water several times until it became gel-like. After centrifugation, the gel was vacuum dried at 80 degC for 8 h to obtain the GO2 powder. Reduction was performed similarly to rGO1.", "measurement_extractions": [ { "quantity": "10 g", "unit": "g", "measured_entity": "Graphite flakes", "measured_property": "mixed" }, { "quantity": "10 g",

Inc. SPBT-1 Bench-Top Solvent Purification System. Compound 1 was synthesized according to literature procedures.9 NbCl5 and Nb(OEt)5 used in the preparation of T-I and T-II were purchased from Sigma-Aldrich and used as received. Commercial Nb2O5 (Puratronic(r), 99.9985%) was purchased from Alfa Aesar and used as received. Pluronic (P123) and dodecylamine 98% were used as structure-directing agents and were purchased from Sigma-Aldrich. Milli-Q water (resistivity 18.2 M\u03a9 cm-1 at 25 degC; 0.22 \u03bcm filter) was used in all preparations and reactions requiring aqueous conditions. \nSynthesis of the Nb2O5 materials discussed within this contribution have been adapted from previously reported procedures. The methods used are briefly described in the following paragraphs:\n5 g of NbCl5 (18.5 mmol) were dissolved in 99% ethanol (10 mL) under constant stirring. To this solution NH4OH (1 M) was slowly added to the aforementioned solution until a white precipitate was observed. The precipitate was then separated from the solution by centrifugation (3000 rpm), washed four times using Milli-Q water and dried at 120 degC for 24 hours. \n5 g of NbCl5 (18.5 mmol) were dissolved in 200 mL Milli-Q water. Immediately after addition, the yellow powder became white. After stirring for 3 h at room temperature, the white precipitate was centrifuged (3000 rpm) and washed four times with Milli-Q water until the filtrate was at neutral pH. The obtained solid was dried at 120 degC for 24 hours. \n1.5 g of P-123 were dispersed in 11 mL of Milli-Q water and 45 mL of HCl (2 M) at 40 degC. 5 g of Nb(OEt)5 (15.7 mmol) was added to solution under stirring. The resulting mixture was kept at 40 degC for 24 hours and then precipitated in a Teflon-lined autoclave at 100 degC for 48 hours. The obtained solid was filtered, washed with Milli-Q water and dried in air at room temperature. Excess surfactant was removed by Soxhlet extraction first by washing with 1% HCl in 95% EtOH (300 mL) and then with 95% EtOH only (120 mL). The final, template-free mesoporous Nb2O5*nH2O was dried in the oven at 120 degC for 18 hours. A mixture of Nb(OEt)5 (3.25 g, 10.3 mmol) and dodecylamine (0.57 g, 3.1 mmol) was heated until a homogeneous solution was obtained. Subsequent addition of 65.4 mL of Milli-Q water with manual stirring resulted in the formation of a gel-like precipitate. Further addition of 27.6 \u03bcL (0.3 mmol) concentrated HCl afforded a white precipitate. The reaction mixture was allowed to stand overnight, sealed and heated at 40 degC for 30 hours, 60-65 degC for 66 hours, 80 degC for 48 hours, and 95-100 degC for 5 days. The solid was then cooled down, collected by filtration and dried at 95-100 degC for 2 hours, 120 degC for 48 hours, and 140 degC for 48 hours. The white solid was then washed four times to remove the presence of excess surfactant. Each washing cycle was conducted for 24 hours under vigorous stirring followed by Buchner filtration. 645 mg (3.4 mmol) of p-toluenesulfonic acid in 13 mL of ether were added to 100 mL of MeOH for the first wash. For the second wash, 65 mg (0.3 mmol) of p-toluenesulfonic acid in 3 mL of ether were added to 100 mL of MeOH. Third and fourth washings were done using MeOH (100 mL) only. The final, template-free mesoporous Nb2O5*nH2O was dried into the oven at 120 degC for 24 hours.", "measurement_extractions": [ { "quantity": "99.9985%", "unit": "%", "measured_entity": "Nb2O5",

simultaneously oxidizing and ultrasonicating\nGraphite powder (Micro 0850) was provided by Asbury Carbons Pty Ltd. Potassium permanganate, sulphuric acid (95-98%) and phosphoric acid (85 wt%) were purchased from Sigma-Aldrich. Hydrogen peroxide (30 wt%) was bought from Chem-Supply. \nKMnO4 (0.4 g) was dissolved in a mixture of concentrated H2SO4 (6.0 g) and H3PO4 (26.0 g). Graphite powder (0.1 g) was added into the mixture and stirred for 1 min. Then the mixture was immediately covered and placed into an ultrasonic bath (200 W and 42 kHz) for simultaneous oxidization and ultrasonication (oxidi-sonication). A cooler was connected with the bath to prevent heat build-up. During the oxidi-sonication, graphite flakes could exfoliate and split into graphene sheets; meanwhile, they were oxidized by Mn2O7 that was created by 2KMnO4 (s) + H2SO4 (aq) - Mn2O7 (l) K2SO4 + H2O. The reaction can be terminated anytime by moving the mixture out of the bath and then adding 120 g water slowly, followed by vacuum filtrating and washing three times with water and hydrogen peroxide for removal of ions and acids. The prepared sheets should be stored in solvents such as water or acetone for the following film fabrication. For characterization in need of powder samples, the sheets were dried in an air-ventilated oven at 60 degC and then in a vacuum oven at 100 degC for 4 hours to remove crystalline water.

The solution was sonicated for about 20 minutes in order to exfoliate the GO sheets that are initially stacked in the dispersion. To this, 50 \u03bcL of diluted hydrochloric acid (HCl, 1 M) were added dropwise and mixed with the solution. The addition of HCl is needed for the later stabilization of the macroemulsion. Thereafter, a toluene solution containing the Cu2-xS NCs (200 \u03bcL) was added to the diluted GO solution. Upon addition of the toluene solution an emulsion was formed in the vial by manual shaking. Subsequently, the emulsion was sonicated in order to decrease droplet size, leading to the formation of a macroemulsion having a milky appearance. Pure toluene/GO macroemulsions (in the absence of Cu2-xS NCs) were prepared in an analogous way, but using pure toluene instead of Cu2-xS NCs in toluene. The reference Cu2-xS NCs samples were prepared by diluting the original NC's solution two times, in order to obtain similar NC's concentration. \nThe synthesis of 5 nm Cu2-xS NCs was performed according to a previous report.8 Typically, the synthesis was performed by mixing 1.25 mmol of ammonium diethyldithiocarbamate, 10 mL of dodecanethiol and 17 mL of oleic acid in a three-neck flask.
