Summary: Magnetostrictive coupling has become a sensitive method for studying magnetism in 2D materials by mechanical means. In this study, we optothermally modulate the magnetization in antiferromagnetic 2D material membranes to induce a high-frequency magnetostrictive driving force. The thermo-magnetostrictive effect near the critical temperature of magnetostrictive 2D materials provides a route for more efficient actuation of nano-magnetomechanical devices and studying the coupling among magnetic, mechanical, and thermodynamic degrees of freedom.

Summary: We observed an unusual weak antiferromagnetic coupling in Fe-based nanowires encapsulated within carbon nanotube buckypapers. A custom-designed Cl-assisted chemical vapour deposition approach was used to produce the samples. The enhancement of the Ar-vapour flow rate had significant effects towards stabilizing the gamma-Fe phase. Magnetic junctions were identified between the Fe3C, alpha-Fe, and gamma-Fe phases. A weak Neel temperature signal at T similar to 130 K was detected.

Summary: Micromagnetic simulations are used to study resonances and microwave assisted magnetic switching (MAS) in two-phase Co/CoPt nanowires. The nucleation, interfacial domain wall pinning, and propagation processes are well distinguished and play a role in the system. The coupling strength varies to cover different hysteresis curves. Interfacial resonances play an important role in MAS, allowing for optimal conditions with low MAS frequencies and dc applied fields while balancing low field usage and short reversal time.

Summary: In this study, g-C3N4/LaFeO3 nanocomposites were successfully synthesized with well-dispersed LaFeO3 nanoparticles on g-C3N4 nanosheets. The g-C3N4/LaFeO3 nanocomposites exhibited excellent photocatalytic activity for the degradation of tetracycline hydrochloride (TC-HCl) antibiotics under visible light irradiation, with a degradation efficiency 13.6-fold and 2.6-fold higher than pristine LaFeO3 nanoparticles and g-C3N4 nanosheets, respectively. The p-n heterojunctions of g-C3N4/LaFeO3 effectively separated photogenerated electrons and holes, leading to the enhanced photocatalytic activity. Moreover, the dominant radical during the photodegradation process was found to be center dot O-2(-) according to active species trapping experiments.

Summary: This study focuses on the utilization of waste lithium-manganese batteries to develop efficient catalysts for the degradation of formaldehyde. The findings suggest that the continuous doping of Li+ and the conversion of Mn(IV) to Mn(III) during the discharge process contribute to the enhancement of the catalyst's degradation efficiency. Additionally, the increase in discharge level promotes the catalytic activity of the catalyst for formaldehyde degradation. The results provide an attractive approach for converting waste lithium battery electrode materials into formaldehyde degradation catalysts to improve indoor air quality.

Summary: In order to improve the gas sensitivity of NO(2) room-temperature sensors based on reduced oxide graphene (rGO), ternary hybrids were synthesized by combining different contents of rGO, ZnO rods, and noble metal nanoparticles (Au or Ag NPs) to utilize the advantages of each component. The presence of rGO in the ZnO-rod/rGO hybrid facilitated the diffusion of gas molecules by preventing rGO stacking and creating a porous structure. Among the tested hybrids, Ag@ZnO rods-2% rGO and Au@ZnO rods-2% rGO exhibited better gas-sensing properties for low concentrations of NO(2), with higher response and shorter recovery time.
