本研究基于最小能量原理（MEP）计算了C3H6O2同系物的热力学稳定性和转动光谱参数，确定了丙酸为最稳定同系物，并通过实验验证了甘油醛的高频转动光谱数据，为星际介质中的天体化学探测提供了新依据。 本文围绕C3H6O2同系物的热力学稳定性与光谱特性展开 ...

When UB chemists analyzed samples of water, fish and bird eggs, they weren’t surprised to find plenty of per- and polyfluoroalkyl substances (PFAS). After all, these “forever chemicals” turn up nearly ...

BUFFALO, N.Y. — When University at Buffalo chemists analyzed samples of water, fish, and bird eggs, they weren’t surprised to find plenty of per- and polyfluoroalkyl substances (PFAS). After all, ...

Abstract: Recent leading zero-shot video object segmentation (ZVOS) works devote to integrating appearance and motion information by elaborately designing feature fusion modules and identically ...

Guangdong University of Technology researchers used a gas chromatography-based method to detect nonylphenol isomers in sewage and wastewater sludge. Scientists from the Guangdong University of ...

Neutron star mergers are astrophysical “gold mines,” synthesizing over half of the elements heavier than iron through rapid neutron capture nucleosynthesis. The observation of the binary neutron star ...

Researchers at Tokyo Institute of Technology for the first time discovered the selective generation of three types of structural isomers (a set of different nanostructures with an identical chemical ...

Nobel laureate Otto Hahn is credited with the discovery of nuclear fission. Fission is one of the most important discoveries of the 20th century, yet Hahn considered something else to be his best ...

New statistical framework developed by researchers at the University of California in Riverside allows confident identification of isomeric molecules by mass spectrometry, even when no unique ...

VOCs can be reliably examined in different environments using chemical ionization mass spectrometers. But when a compound has been masked by either an isobaric or isomeric interference, this exhibits ...
