Abstract Anaerobic digestion (AD) is a well-known biological conversion process to obtain gaseous biofuel from organic matter: in fact, upgrading biogas biomethane mean substitute conventional natural gas. It also known that biochar can improve the production AD processes. In this work, different biochars have been produced various feedstocks at conditions. Biochars obtained carbonization of wh...

Kazuaki Ishihara While the Nobel Prize in Chemistry 2001 was awarded to Knowles, Noyori, and Sharpless for development of asymmetric catalytic reactions using metal-based catalysts, 2021 List MacMillan organocatalysis. This timeline serves highlight two crucial points: 1. Catalysis, i. e., cost-, energy-, atom-efficient remain paramount importance human society; 2. Focus has shifted from (trans...

Bleach, nitrite, chromate, and hydrogen peroxide-peroxidase are effective urine adulterants used by the illicit drug users to conceal marijuana-positive results. Methods for detecting nitrite and chromate are available. Effects of other oxidizing agents that could possibly be used as adulterants and are difficult to detect or measure are presented in this report. Urine samples containing 40 ng/...

The oxomanganese complex [H(2)O(terpy)Mn(III)(μ-O)(2)Mn(IV)(terpy)H(2)O](3+) (1, terpy = 2,2':6-2″-terpyridine) is a biomimetic model of the oxygen evolving complex of photosystem II with terminal water ligands. When bound to TiO(2) surfaces, 1 is activated by primary oxidants (e.g., Ce(4+)(aq), or oxone in acetate buffers) to catalyze the oxidation of water yielding O(2) evolution [G. Li et al...

When young children do not receive adequate amounts of the micronutrient iodine in their diet, their growth and cognitive development can be impaired. Nearly every country in the world has programs in place to track iodine intake and provide supplemental iodine if needed, usually in the form of fortified salt. The iodine nutrition status of a population can be tracked by monitoring iodine level...

Cis-polybutadiene was functionalized using in–situ generated DMD as oxidant and tetra-n-butyl ammonium bromide as phase transfer catalyst (PTC). The epoxidation process was investigated by 1HNMR spectroscopy. 1HNMR spectrum analysis of products confirms the absence of ring opening side products in epoxidation reaction. Various factors such as reaction temperature, reaction time and the concentr...
