Low-Cost Copper Zinc Tin Sulfide Counter Electrodes for High-Efficiency Dye-Sensitized Solar Cells** Xukai Xin, Ming He, Wei Han, Jaehan Jung, and Zhiqun Lin* Dye-sensitized solar cells (DSSCs) are among the most promising photovoltaic devices for low-cost light-to-energy conversion with relatively high efficiency.[1] A typical DSSC
In this study, synthesis of copper nanoparticles was performed using organoclay as a support to stabilize the nanoparticles. Organoclay amount was gradually increased, which had an effect on the morphology of the resultant nanoparticles. Low amount of organoclay added resulted in larger and agglomerated copper nanoparticles whereas increased amount of organoclay gave smaller sized .

Vermiculite decorated with copper nanoparticles is a new antibacterial material that was prepared in this study through ion-exchange process and hydrogen reduction.
&#; Vermiculite Vermiculite is a high-charge:phyllosilicate clay mineral. It is generally regarded as a weathering product of micas. Vermiculite is also hydrated and somewhat expansible though less so than smectite because of its relatively high charge. Granular clay absorbents, such as vermiculite, have been used for over.

This paper shows effective removal of copper from water and industrial wastewater by modified magnetic nanoparticle with benzotriazole as an efficient adsorbent. The method is fast, simple, cheap, effective and safe for treatment of copper polluted waters. Non-modified magnetic iron oxide nanoparticles (MIONPs) can adsorb up to 49.6% of 50 ng ml-1 of Cu (ΙΙ) ions from polluted water, but ...
2.2 Synthesis of Copper nanoparticles. A 500 mL of 0.01 molar Copper (II) Chloride (CuCl2.2H2O) solution was prepared by dissolving that copper salt in de-ionized water. Solutions of 0.25M, 0.5M, 0.75M and 1.0M L-Ascorbic Acid were prepared in de-ionized water.
Efficient harvesting of electrokinetic-streaming-potential requires a trade-off between high flow-rate and nanofluidic confinement. To attain the best out of these parameters, we have developed a periodic network of tetrahedral and octahedral voids interconnected through fine biconical nanofluidic channels by close-packing nearly monodisperse silica spheres of diameters 285, 620, 1000, 1750 ...

After four recycles, the removal efficiency of Cr(VI) by AVT-nZVI still maintained above 70%, which was higher than those by clay-supported nZVI materials in the previous reports (Shi et al., 2011b; Diao et al., 2016). The decreased removal efficiency might be explained by two reasons.
A copper indium gallium selenide solar cell (or CIGS cell, sometimes CI(G)S or CIS cell) is a thin-film solar cell used to convert sunlight into electric power. It is manufactured by depositing a thin layer of copper, indium, gallium and selenium on glass or plastic backing, along with electrodes on the front and back to collect current. Because the material has a high absorption coefficient ...
