Reduction of esters by a novel photocatalyst      (via sciencedaily.com)     Original source 

A ubiquitous compound, called ester can be broken down to produce desirable alcohols and other chemicals for use across industries including pharmaceuticals and cosmetics, but the process can be costly, both financially and in terms of the environment. Researchers developed a novel photocatalyst 'N-BAP.' When irradiated with blue light, the photocatalyst reduces esters in the presence of oxalate, a negatively charged molecule found widely in nature, resulting in the desired alcohols.

Mobile monitoring for an airborne carcinogen in Louisiana's 'Cancer Alley'      (via sciencedaily.com)     Original source 

Louisiana's southeastern corridor is sometimes known colloquially as 'Cancer Alley' for its high cancer incidence rates connected to industrial air pollution. Most of the region's air pollution-related health risks are attributed to ethylene oxide, a volatile compound used to make plastics and sterilize medical equipment. Researchers measured concerning levels of ethylene oxide in this area with mobile optical instruments, a technique they say could improve health risk assessments.

Looking for a new battery platform? Focus on the essentials      (via sciencedaily.com)     Original source 

In facing life's many challenges, we often opt for complex approaches to finding solutions. Yet, upon closer examination, the answers are often simpler than we expect, rooted in the core "essence" of the issue. This approach was demonstrated by a research team in their publication on addressing the inherent issues of solid-state batteries.

Scientists 'read' the messages in chemical clues left by coral reef inhabitants      (via sciencedaily.com)     Original source 

What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex 'soup' that is hard for scientists to decipher. Now, researchers have demonstrated a way to extract and identify these indicator compounds in seawater. They found metabolites previously undetected on reefs, including three that may represent different reef organisms.
