Breaking the C-H bonds in Hydrocarbons to Synthesize Complex Organic Molecules

Chemistry, Organic Chemistry, Science /

The carbon-hydrogen bonds in alkanes – especially those at the ends of the molecules, where each carbon has three hydrogen atoms connected to it– are tough to “crack” if you want to change the hydrogen atoms with other atoms. Methane (CH4) and ethane (CH3CH3) are composed, specifically, of such tightly adhered hydrogen atoms. In the […]

Interference Results in Inaccurate Raman Spectroscopic Analysis of Vitamin B12

Analytical Chemistry, Chemistry, Science /

Plenty of natural products are complex organic molecules. Regardless of this intricacy, researchers are typically able to investigate them using spectroscopic techniques. Nevertheless, a team of scientists has found that caution should be taken using Raman spectroscopy to analyze specific chiral molecules (molecules that have handedness; i.e., they can exist in two “mirror image” kinds

Wash Your Hands for 20 Seconds: Physics Shows Why

Interdisciplinary Science, Mathematical Physics, Science /

Despite hand-washing being confirmed effective in combating the spread of illness and infection, its physics has rarely been studied. However, in Physics of Fluids, by AIP Publishing scientists from Hammond Consulting Limited describe a straightforward model that catches the essential mechanics of hand-washing. They estimated the time scales on which particles, like viruses and bacteria,

Hybrid-Electric Airplane Idea May Reduce Aviation’s Air Pollution Trouble

Applied Science, Aviation Science, Science /

The proposed layout might minimize nitrogen oxide exhausts by 95 percent, a brand-new study finds. At cruising altitude, planes launch a constant stream of nitrogen oxides into the environment, where the chemicals can stick around to create ozone and fine particulates. Nitrogen oxides, or NOx, are a significant source of air contamination and are connected
