The aim of the present study is to develop a simple and convenient co-precipitation method to synthesize Mn(VO₃)₂ nanorods with the aid of polysorbate as the polymeric capping agent in an aqueous environment. The energy-dispersive X-ray spectroscopy, X-ray diffraction, scanning electron microscopy, diffuse reflectance spectroscopy, and vibrating-sample magnetometer techniques were applied to characterize chemical structure, morphology, and optical properties of nanorods. According to the XRD and SEM results, various polysorbate has direct impact on the morphology and crystal size. The photocatalytic performance of the synthesized Mn(VO₃)₂ nanorods was evaluated by monitoring the photodegradation of methylene blue under UV light irradiation. Moreover, the influences of various parameters, such as nanorods size, various dyes, and reaction pH on the photocatalytic stability were studied.

Developing nonprecious metal-based electrocatalysts with exceptional activity and durability for water electrolysis remains a significant challenge. Herein, we report a highly efficient bifunctional electrocatalyst composed of sulfur-doped vanadium metal-organic frameworks (S@V-MOF) integrated with multiwalled carbon nanotubes (MWCNTs) to promote the synergistic effect between S@V-MOF and MWCNTs and modulate the electronic structure of the catalyst, which eventually enhanced its electrocatalytic performance. The S@V-MOF/MWCNT catalyst loaded at the Ni foam electrode exhibits remarkable activity for both the hydrogen evolution reaction (HER) in acidic media and oxygen evolution reaction (OER) in alkaline media, requiring overpotentials of 48 and 227 mV, respectively, to reach a current density of 10 mA cm.

The disinfection of drinking water is essential for eliminating pathogens and preventing waterborne diseases. However, this process generates various disinfection byproducts (DBPs), which toxicological research indicates can have detrimental effects on living organisms. Moreover, the safety of these DBPs has not been sufficiently assessed, underscoring the need for a comprehensive evaluation of their toxic effects and associated health risks.

Helical carbon nanotubes (HCNTs) with different geometrical properties were constructed and incorporated into nanocomposites for the investigation of the anti-crack mechanism. The interfacial mechanical properties of the nanocomposites reinforced with straight carbon nanotubes and various types of HCNTs were investigated through the pullout of HCNTs in the crack propagation using molecular dynamics (MD). The results show that the pullout force of HCNTs is much higher than that of CNTs because the physical interlock between HCNTs and matrices is much stronger than the van der Waals (vdW) interactions between CNTs and matrices.

Magnesium-based materials, which are known for their light weight and exceptional strength-to-weight ratio, hold immense promise in the biomedical, automotive, aerospace, and military sectors. However, their inherent limitations, including low wear resistance and poor mechanical properties, have driven the development of magnesium-based metal matrix composites (Mg-MMCs). The pivotal role of powder metallurgy (PM) in fabricating Mg-MMCs was explored, enhancing their mechanical and corrosion resistance characteristics.
