The hydrodenitrogenation (HDN) reactivities of various nitrogen-containing compounds in petroleum fractions and their structural characteristics are briefly introduced,including their reaction mechanisms,reaction networks and kinetics.Accordingly,new trends in developing high-performance HDN catalysts are also re...
Or, as an English proverb goes, 'If there is a will, there is a way. ' Our world is becoming increasingly competitive and only by making strong-willed efforts can we maximize our potential and gain competitive edges, and prevail ov 要做不可能可能,我们必须行使我们的坚持不懈和强的自我克制...

The selective transformation of nitrogen compounds is a foundation of the modern chemical industry. Existing thermochemical processes largely rely on fossil fuels and innovating electrocatalytic processes that could use renewable energy remains challengi
The versatility of aza- and oxa-heterocyclic compounds has garnered significant attention in recent times. A large number of currently approved pharmaceutical products include nitrogen- and oxygen-containing heterocycles. Recent nanotechnological developments have propelled an upsurge in the applications of ...
chief commercial method of fixing nitrogen (incorporating elemental nitrogen into compounds) is the Haber-Bosch process for synthesizing ammonia. This process was developed duringWorld War Ito lessen the dependence of Germany on Chileannitrate. It involves the direct synthesis of ammonia from its ...
The Arabidopsis L-type Amino Acid Transporter-5 (LAT5; At3g19553) was recently studied for its role in developmental responses such as flowering and senescence, under an assumption that it is a polyamine uptake transporter (PUT5). The LATs in Arabidopsis have a wide range of substrates, incl...
and its components, except for SOA where a decreased risk was observed. Higher risk increases were observed for CVD mortality (e.g., 18% [95% CI 1–39%] per IQR for NO2). These findings at low exposure levels are relevant for future decisions concerning air quality policies....
