The Latest Progress in the Chemistry of Alkaloids.

alkaloids (DAs) are interesting molecules with rich molecular skeletons and diverse biological activities. Since their discovery, phytochemists have isolated, purified, and identified more than 350 DAs. Synthetic chemists, attracted by the structure and activity of DAs, have accomplished many elegant synthetic jobs.

Defect-Rich Regulatory Activity Strategy: Disordered Structure for Enhanced Catalytic Interfacial Reaction of Chlorobenzene.

In contrast to previous defect engineering methods, the preparation of amorphous materials can obtain abundant defect sites through a simple way, which is expected to effectively degrade Volatile Organic Compounds (VOCs) under milder conditions. However, in-depth and systematic studies in this area are still lacking. Novel types of amorphous CeMn catalysts with abundant defects were prepared through simple hydrothermal synthesis and used for Cl-VOCs catalysis for the first time.

MS2/GmAMS1 encodes a bHLH transcription factor important for tapetum degeneration in soybean.

GmAMS1 is the only functional AMS and works with GmTDF1-1 and GmMS3 to orchestrate the tapetum degeneration in soybean. Heterosis could significantly increase the production of major crops as well as soybean [Glycine max (L.) Merr.

Effect of Pd/Ce loading on the performance of Pd-Ce/γ-AlO catalysts for toluene abatement.

A single metal Pd/γ-AlO catalyst and a bimetallic Pd-Ce/γ-AlO catalyst were prepared by the equal-volume impregnation method to investigate the effect of CeO loading on the catalytic oxidation of toluene. The specific surface area, surface morphology, and redox performance of the catalyst were characterized by N desorption, scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), H-TPR, O-TPD, and electron paramagnetic resonance (EPR). The results showed that bimetal catalysts loaded CeO had smaller nano-PdO particles than those of the Pd/γ-AlO catalyst.
