The Earth's atmosphere has strengthened its ability to remove air pollutants, including the potent climate-warming gas ...

Scientists have discovered that the Earth’s atmosphere is getting better at removing air pollution, including methane, one of the most powerful greenhouse gases. This new research, published in Nature ...

WE would like to confirm Weinreb, Barrett, Meeks and Henry's 1 discovery of the hydroxyl (OH) radical in the interstellar medium at frequency 1667.36 Mc/s. Fig. 1. shows observations of the ...

NHS-PEG-OH（NHS活性酯-聚乙二醇-羟基）是一种化学试剂，常用于生物化学和生物医学研究中，特别是在分子标记、药物输送和表面修饰等领域。

Scientists from the Henan Academy of Sciences recently developed a new technique for the determination of hydroxyl polycyclic ...

OH emission, also known as hydroxyl airglow, is a natural phenomenon that occurs in Earth’s upper atmosphere, specifically in the mesosphere and lower thermosphere region. It’s characterized ...

A primary alcohol is one in which the hydroxyl group (–OH) is attached to a carbon atom with at least two hydrogen atoms. This will only occur when the hydroxyl group is at the end of the ...

A crucible’s performance is dependent on properties, such as viscosity, which in turn is dependent on the presence of impurities, such as the hydroxyl (OH) groups content, according to the ...

Compared with alkanes, alcohols have significantly higher boiling points. The hydroxyl groups in alcohol molecules are responsible for hydrogen bonding between the alcohol molecules. As greater ...
