Graphene, a carbon-based substance with a dense honeycomb crystal structure, has a huge surface area, good mechanical strength, and outstanding electrical conductivity. Thus, it favours electrochemical responses when deposited on an electrode. GO undergoes rapid agglomeration, while rGO can be stored ...

When a solution of DPPH is mixed with a substance that can donate a hydrogen atom, DPPH is reduced with the loss of its violet colour to pale yellow. In the DPPH free radical scavenging assay, the IC50 values of the leaf extracts were in the order, methanol (60.85 ± 2.67 ...
In this study we developed the Attribution Questionnaire-Substance Use Disorder (AQ-SUD) by modifying the Attribution Questionnaire, a commonly used measure of public mental illness stigma. We examined 1) the psychometric properties of the AQ-SUD with supporting data from other stigma scales and 2...
The need for new antibacterial drugs to treat the increasing global prevalence of drug-resistant bacterial infections has clearly attracted global attention, with a range of existing and upcoming funding, policy, and legislative initiatives designed to r
What mass of oxygen will react with 2.64 g of magnesium? The reaction is: 2Mg + O_2 to MgO. How many grams of phosphoric acid will be produced by the following reaction? Ca3(PO4)2 + 3SiO2 + 5C + 5O2+3H2O --> 3CaSiO3 + 5CO2 + 2H3PO...
After the addition was complete and the color of the mixture turned yellow, a small amount (0.78 g after drying) of a brick-red insoluble substance was filtered off. The aqueous layer was separated and extracted with methylene chloride (2 Â 100 ml). The combined organic solutions were ...
Apiose is a natural pentose containing an unusual branched-chain structure. Apiosides are bioactive natural products widely present in the plant kingdom. However, little is known on the key apiosylation reaction in the biosynthetic pathways of apiosides. In this work, we discover an apiosyltran...
