Summary: A monodispersed core-shell mesoporous H-Fe3O4@mTiO2 magnetic microspheres adsorbent was prepared for efficient arsenic removal, showing high specific surface area and magnetic susceptibility for easy separation. The adsorbent exhibited high adsorption capacities for both As(V) and As(III), especially showing excellent performance for As(III) removal across a broad pH range. Furthermore, the adsorbent showed excellent stability after 5 regeneration cycles due to its advantageous magnetic inner-core for fast solid-liquid separation without any loss.

Summary: A green synthesis route was developed to produce a visible-light-driven thin carbon layered titanium dioxide (CLT) nanocomposite using ascorbic acid as the carbon precursor. The presence of a thin layer of carbon on the TiO2 surface was observed, and the thickness of the carbon layer was found to be proportional to the concentration of carbon precursor. The CLT nanocomposite exhibited improved surface area and photocatalytic activity compared to commercial TiO2, and it also showed antibacterial activity against E. coli.

Summary: This study developed a method to fabricate humidity-sensitive bilayer actuators with programmable deformation. Laser cutting was used to pattern the active layer made of polypyrrole (PPy), which was then transferred to an inert polyethylene terephthalate (PET) tape to form a bilayer actuator. Numerical and experimental studies confirmed the humidity-sensitive and programmable twisting behaviors of the patterned bilayer actuators. The developed method can be widely applied to other types of soft actuators and holds promises in areas such as smart materials and structures.

Summary: Due to their tunable properties, 2D materials, including MXenes, are widely used in optoelectronic devices for their conductivity and transparency. MXenes, which can be synthesized as a colloidal solution, are hydrophilic and can be easily coated on different substrates, making them suitable for applications, such as solar cells. This study simplified the fabrication of MXenes-based solar cells by spin-coating Ti(3)C(2)Tx-MXenes on an n-type Si substrate. The efficiency of the solar cells was improved through treatments such as Al2O3 deposition, AuCl3 doping, and texturing of the silicon substrate.

Summary: This study investigates the decomposition of H2O2 over six different iron minerals and finds hematite and goethite to be the most promising minerals for environmental cleanup due to their high ROS production. Magnetite and maghemite are highly active for both H2O2 decomposition and O-2 production at neutral and basic pHs. Ferrihydrite and feroxyhyte, on the other hand, are problematic minerals for CHP as they have high O-2 production and negligible ROS generation at all pHs.

Summary: In this study, graphene oxide (GO) was nano-architected with nano Fe3O4 functionalized cellulose nanocrystals (Fe-CNC) to enhance the thermal conductivity of GO/Fe-CNC composite films. Through a thermal reduction process at 1500°C, Fe/Fe3C nanoparticles were formed in the reduced GO/Fe-CNC matrix, which served as connections between the reduced GO (R-GO) sheets and carbonized cellulose nanocrystals. The defects on R-GO were repaired by Fe through a catalytic graphitization process, reducing the scatterings of phonons. The obtained flexible and lightweight composite film of R-GO/Fe-CNC exhibited a high thermal conductivity.
