N/O double-doped biomass hard carbon material realizes fast and stable potassium ion storage

Mengmeng Yang et al.

Summary: N/O co-doped cage-type biomass carbon (NOBC) prepared in this study exhibited superhigh long-cycling performance and rate performance as the anode of a potassium ion battery. The excellent performance can be attributed to the unique structure, internal 3D carbon network, and N/O co-doping, contributing to high reversible capacity even at high current densities. The pseudo-capacitance mechanism and N/O double doping were crucial in promoting K ion adsorption and improving conductivity in NOBC materials.

Multi-band and high-sensitivity perfect absorber based on monolayer graphene metamaterial

Liying Jiang et al.

Summary: This study utilizes the Finite Difference Time Domain (FDTD) method to simulate a multi-band ideal absorber and proposes a new method based on critical coupling and guided resonance. The physical mechanism is analyzed through impedance matching and coupled mode theory (CMT). By adjusting the geometric parameters of the structure, the spectral position and absorption rate of the absorption peak can be tuned.

Tert-butylamine/oleic acid-assisted morphology tailoring of hierarchical Bi4Ti3O12 architectures and their application for photodegradation of simulated dye wastewater

Tingting Cheng et al.

Summary: This study reports the morphology tailoring of hierarchical Bi4Ti3O12 architectures using tert-butylamine (TB) and oleic acid (OA), revealing the significant influence of TB and OA content on the resulting morphologies. Photodegradation experiments showed that the nanosheet-assembled hierarchical microrods exhibited superior activity in degrading dye wastewater. Interestingly, the photodegradation process of mixed dye solutions differed from that of individual dye solutions, indicating a complex photodegradation mechanism of Bi4Ti3O12 photocatalysts.
