Investigation and Characterization of Composite Silica Aerogel Nanostructures Obtained Via Magnetron Sputtering
This study explores the deposition of Copper (Cu) onto hydrophilic Silica Aerogel (SA) monoliths using magnetron sputtering, with Cu thicknesses of 20 nm, 50 nm, and 100 nm. Leveraging the mesoporous nanostructure of SA, a Cu-sputtered SA nanocomposite was fabricated, creating a non-homogeneous …

Low temperature photoluminescence studies on sputter deposited cadmium sulphide/cadmium telluride heterojunctions and solar cells
… at higher excitation powers. The effect of copper (Cu) used in making back contacts was studied in connection with the CdS/CdTe junction PL. It was found that the presence of Cu suppresses the sub-band gap PL emissions. This effect is thought to be either due to Cu occupying cadmium …

Corn responses to high levels of copper application as copper rich pig manure
The use of copper (Cu) in pig production to stimulate growth and improve feed efficiency is presently being questioned due to the potential environmental hazards associated with the repeated disposal of the resulting Cu rich manure in agricultural land. Results of field experiments conducted on …

Geochemical Constraints of Porphyry Cu Deposits-Forming Magmas in Sonora, Mexico
Porphyry Cu deposits (PCDs) represent the most significant source of economic-grade copper (Cu) on Earth (Sillitoe, 2010). PCD formation is intimately linked to the magmatic and tectonic evolution of convergent margins (Sillitoe, 2010). While the metallogenic characteristics of PCDs have been …

Electrodeposition of Copper on Ruthenium Oxides and Bimetallic Corrosion of Copper/Ruthenium in Polyphenolic Antioxidants
Copper (Cu) electrodeposition on ruthenium (Ru) oxides was studied due to important implications in semiconductor industry. Ruthenium, proposed as the copper diffusion barrier/liner material, has higher oxygen affinity to form different oxides. Three different oxides (the native oxide, reversible …

The Effects of Known PCR Inhibitors on Droplet Digital PCR Performance
… real-time PCR (qPCR) instrumentation, the current standard for the quantification of DNA, are used to detect inhibitors in samples. Droplet digital PCR (ddPCR) relies on absolute quantification of positive and negative droplets and therefore may be less susceptible to inhibition than …
