Summary: Polymeric membranes are in high demand for biofuels. UV-induced crosslinking offers a controllable and ultrafast method for membrane fabrication, but the poor compatibility between the photoinitiator and polymer poses a challenge for large-scale production. In this study, we develop a polydimethylsiloxane prepolymer functionalized with both a photoinitiator and photocrosslinker, allowing for self-initiation and self-polymerization. The resulting membranes exhibit excellent performance for bioethanol enrichment compared to current polymeric membranes.

Summary: This study introduces a new strategy called 3D co-printing technology, which utilizes a dual-light curing process to fabricate 3D electronics selectively. By using only one printing material, this technology addresses the challenge of conventional methods that require multiple materials deposition processes. The resistivity of the resulting conductive trace can be controlled by adjusting material formulation and processing parameters.

Summary: 3D printing technology is used for various applications, including electronics, but requires the development of novel 3D printable materials to produce complex structures. This study reports the synthesis of 3D printable photocurable resins embedding Ti3C2Tz-MXenes, a class of 2D layered materials with excellent electronic properties. Stable inks suitable for Digital Light Processing 3D printing technology were successfully synthesized and used to fabricate complex 3D composite structures. Annealing treatments were performed to enhance the electrical conductivity of the material, resulting in objects with improved conductivity and opening new possibilities for the development of complex 3D electronics.

Summary: In this study, a strongly coupled hybrid photocatalyst consisting of polymeric carbon nitride (CN) and a two-dimensional conductive Zn-containing metal-organic framework (Zn-MOF) was reported. The catalytic capability of Zn-MOF for H2O2 production was unlocked by annealing-induced effects. The annealing treatment not only activated the Zn sites in Zn-MOF to a relatively electron-rich state but also facilitated photoelectron migration from the CN photocatalyst to the Zn-MOF catalytic unit, resulting in significantly enhanced H2O2 production activity and excellent stability.

Summary: The study presents an example of near-infrared light-triggered enantioselective photopolymerization reactions using NaYF4 nanophosphors and chiral silver nanoparticles, resulting in a polydiacetylene film with high optical activity and chiral fluorescence. The manipulation of optical activity allows for easy control of the preferred screw direction of helical PDA chains. The proposed explanation is based on the electromagnetic field enhancement effect, which suggests that both enantioselectivity and reactivity benefit from resonance between upconverted emission and enhanced electromagnetic field near chiral AgNPs.

Summary: Conductive polypyrrole/UV cured acrylate nanocomposite coatings were prepared using simultaneous photopolymerization, with mechanical and conductive properties correlated to structural and compositional changes. SEM showed closer deposition of polypyrrole/Ag composite particles to the substrate, while AFM revealed conductivity only in coatings with formulations containing 45% or more pyrrole and AgNO3 mixture at the top.

Summary: Heavy metal toxicity affects aquatic plants and animals, causing disturbances in biodiversity and ecological balance. Microorganisms and plants have been widely used in bioremediation of heavy metals. This study explores the metal tolerance ability of Sporosarcina pasteurii SRMNP1, a gram-positive bacterium, which can convert metal ions into nanoparticles and efflux them through vesicle budding. The study also reveals excessive secretion of extracellular polymeric substances by the strain to discharge the metal particles.
