Summary: This study focuses on the fractionation of lignin from corn stalk enzymatic hydrolysis to reduce heterogeneity and improve the microstructure and electrochemical performances of lignin-derived carbon materials. The results show that the fractionation process successfully obtained three lignin fractions with sequentially increasing molecular weight and specific surface area. Among them, the F3-derived carbon material (LC-F3) exhibits the highest specific surface area and the best heteroatom doping effect. Moreover, LC-F3 also shows excellent specific capacitance and cycling stability, which can be attributed to its high disordered level, heteroatom doping density, and specific surface area.

Summary: A direct oxidative radical decarboxylative cyanomethylation of carboxylic acids using 3-azido-2-methylbut-3-en-2-ol as the carbon-centered radical acceptor is described. The method is applicable to various α-amino acids, α-oxy acids, α-keto acids, pentofuranuronic acids, and hexopyranuronic acids. Mechanistic investigations suggest the involvement of a radical process. This work provides a potential approach to synthesize biologically relevant β-amino acids, 5-deoxy-hexofuranose, and 6-deoxy-heptose constructs.

Summary: Aspergillus niger produces ochratoxin A (OTA), which is genotoxic and carcinogenic. In this study, a gene encoding the transcription factor Azf1 was deleted in A. niger, resulting in complete blockage of OTA production. The deletion of Azf1 also led to decreased levels of reactive oxygen species (ROS) and impaired oxidative phosphorylation, which ultimately prevented OTA biosynthesis.

Summary: In this work, an innovative method is investigated to control the current distribution of the radiating patch by adjusting the input phase, resulting in both pattern and polarization reconfigurable characteristics. A compact and low-profile antenna with four fed ports is designed to implement this method, allowing for linear, RHCP, and LHCP polarization with different beam directions. A passive planar array is also designed and fabricated based on this antenna element, which can scan a coverage of +/- 70 degrees with low gain fluctuation and low sidelobe. The proposed antenna is a good solution for wireless communication systems due to its simple configuration, multifunction, and beamforming capability.

Summary: Hydrogenolysis is an effective method for converting polyolefins into high-value chemicals. In this study, the activity of CeO2-supported Ru single atoms, nanoclusters, and nanoparticles in LDPE hydrogenolysis showed a volcanic trend. Metal-support interactions and hydrogen spillover effect were identified as the two key factors in the reaction. Only when the balance between these two effects is achieved, as in CeO2-supported Ru nanoclusters, can the hydrogenolysis activity be promoted.

Summary: In this study, the expression levels and role of MDM2 in non-functioning PitNET patients were measured, and the effect of etoposide on the cell bioactivity of the GT1-1 cell line was investigated. The results showed that patients with high MDM2 had more invasive behavior, were younger, more frequently female, and had larger tumor sizes. MDM2 played a role in tumorigenesis of NF-PitNET independently of p53, and etoposide showed anti-tumor activity in GT1-1 cells.

Summary: Decorating single atoms of transition metals on MXenes enhances the electrocatalytic properties of the resulting composites. In this study, cobalt single atoms were anchored onto several commonly used MXene substrates, and the electrocatalytic behavior and mechanisms were systematically studied. The Co@V2CTx composite showed lower overpotentials for oxygen and hydrogen evolution reactions compared to other composites, making it comparable to commercial noble metal electrocatalysts. The enhanced catalytic performance of Co@V2CTx was attributed to optimized electronic structure and accelerated catalytic kinetics. This study sheds light on the origins and guidelines for designing efficient MXene-based electrocatalysts.
