Catalytic activity of Au nanoparticles Au is usually viewed as an inert metal, but surprisingly it has been found that Au nanoparticles less than 3–5 nm in diameter are catalytically active for several chemical reactions. We discuss the origin of this effect, focusing on the way in which the chemical activity of Au may change…

Hydroxamic Acids in Nature: Sophisticated ligands play a role in iron metabolism and possibly in other processes in microorganisms The hydroxamic acid bond occurs in products from fungi, yeast, bacteria, and plants. The —CON(OH)— bond arises by oxidation of a free or bound amino group in a unit structure which is often closely related to…

A simple method for the microscale preparation of mosher’s acid chloride Mosher’s acid is treated with oxalyl chloride in the presence of DMF in hexane. Filtration and concentration provide the acid chloride which is suitable for use without further purification. The procedure is amenable to microscale. Mosher’s acid is treated with oxalyl chloride in the…

Thiobarbituric acid test for monitoring lipid oxidation in meat Lipid oxidation is a significant problem relative to off-flavour and off-odour, and warmed-over flavour appears to be related to lipid oxidation in meat. In this review article the thiobarbituric acid (TBA) test for lipid oxidation measurements is described. Works on other techniques to measure lipid oxidation,…

Ischemic stroke is characterised by ischemia-reperfusion damage, which happens when blood flow is restored after a period of ischemia. Thrombolysis with thrombolytic reagents such tissue plasminogen activator (tPA) or mechanical removal can be used to restore blood flow. Ischemia causes inflammation by causing the production of Nf-kb, adhesion molecules, and the upregulation of toll-like receptors,…

If we work for a more sustainable future, the most significant roadblock is the quality and cost-effectiveness of plastics in most industries. As a result, bacterial polyhydroxyalkanoates (PHAs) tend to be a promising candidate for replacing non-biodegradable plastics and combating the contamination caused by their accumulation over time. PHA are energy stores created by microbial…

The subject of functions with non-decreasing increments has gained prominence in many branches of mathematics in recent decades, and due to its relevance, it has attracted the attention of many mathematicians. We’d like to figure out what the relationship(s) are between functions with non-decreasing increments and the arithmetic integral mean, Wright convex functions, convex functions,…
