Panax notoginsengis widely distributed in Yunnan, Guangxi and Jiangxi province of China and its roots have been used as a traditional Chinese medicine for the treatment of hemorrhages, blood stasis and improvement of blood circulation and remission pain1. In recent years, the investigations regarding ...
The presence of an aqueous electrolyte has been shown to reduce the total cell potential for anion exchange membrane-based CO2 electrolysers13,22. An IrO2 anode was utilized for CO2 reduction, due to its stability in neutral pH. The gas product stream was then fed to the cathode chamber ...
Sealed Chlamydomonas reinhardtii cultures evolve significant amounts of hydrogen gas under conditions of sulfur depletion. However, the eukaryotic green alga goes through drastic metabolic changes during this nutritional stress resulting in cell growth inhibition and eventually cell death. This study aimed ...
Hydrogen gas, H2, reacts explosively with gaseous chlorine, Cl2, to form hydrogen chloride, HCl(g). What is the enthalpy change for the reaction of 1 mole of H2(g) with 1 mole of Cl2(g) if both the r What is the boiling point of water in Kelvins? A sample of solid ammonium chl...
Determination of fatty acids in infusions from seeds ofL. usitatissimumL. The esterified sample was used to determine the fatty acid composition. The sample was prepared according to Zhang et al. [84] using Varian 450-GC gas chromatograph with a flame ionization detector (FID) equipped with Sele...
The wet shells were transferred to plastic containers and placed in an oven at 80 °C until dry. Then, dried shells were passed through a sample grinder until a fine beige powder was obtained. To remove labile compounds remaining in the peanut shell, an exhaustive MeOH wash was performed ...
Low durability is the major challenge hindering the large-scale implementation of proton exchange membrane fuel cell (PEMFC) technology and corrosion of carbon support materials of current catalysts is the main cause. Here, we describe the finding of remarkably high durability with the use of a nov...
