A total of 1110 broiler cockerels were used in three experiments to determine the availability of iron and copper from various sources. A skim milk basal diet was fed in each experiment using chicks maintained in battery brooders beginning at one day of age. Four organic iron compounds (sequestered iron A' and ferric choline chloride in Experiment 1 and sequestered iron B and C in Experiment 2)...

Abstract Cuprous oxide (Cu2O) nanoparticles were successfully synthesized using cupric hydroxide gel as a precursor and glucose reductant. A well-dispersed was prepared by treatment of aqueous cuprous chloride with anion exchange resin. The average diameter the Cu2O 780 nm. Attenuated total reflectance Fourier transform infrared spectroscopy showed that polyethylene from resin present in powder...

In the course of an investigation, still in progress, of the physiological activity of a group of soil organisms, it became necessary to determine the quantity of dextrose in a series of solutions. It was desirable to have a method as accurate as the Fehling gravimetric one but which would yield results about as quickly as by direct titration. The reducing sugar present in the 150 cc. of each o...

Solar water splitting is a promising technique for harvesting solar energy and converting abundant sunlight into storable hydrogen fuel. The cuprous oxide photocathode, one of the best-performing photocathodes, possesses theoretical photocurrent density up to 14.7 mA cm ?2 photovoltage as large 1.6 V, making it possible convert in low-cost way. Herein, comprehensive review improving performance...

Electrochemical conversion of carbon dioxide (CO2) to small organic fuels (e.g. formate, methanol, ethylene, ethanol) is touted as one of the most promising approaches for solving the problems of climate change and energy security. In this study, we report the highly efficient electrochemical reduction of CO2 using cuprous oxide (Cu2O) electrodes to produce ethylene (C2H4) primarily. During CO2...

Dinitrosalicylic acid was introduced by the author in 1921 as a reagent for the estimation of sugar in normal and diabetic urine.1 It has also been found to be a valuable reagent for the detection of aIbumin in urine and has been used for the determination of the titratable alkali of the blood.2 During the past 3 years several improvements have been made in the method for the determination of s...
