Summary: As noble metals, high atomic number elements can localize X-ray radiation within tumor cells by exploiting different mechanisms. In this study, alginate-coated platinum nanoparticles were synthesized and used as a radiosensitizer to enhance X-ray therapeutic efficacy in breast cancer. The nanoparticles not only improved biocompatibility and stability, but also induced higher levels of intracellular ROS and enhanced cancer cell death under X-ray irradiation. Both in vitro and in vivo results demonstrated the radiosensitizing properties of the nanosystem. The importance of radiosensitizers for improving radiotherapy outcomes was highlighted.

Summary: We report the growth of silicon nanowires (SiNWs) using a novel Cu-In bimetallic catalyst and plasma-enhanced chemical vapor deposition (PECVD). The structure of the catalyst nanoparticles (NPs) is studied throughout a two-step process involving a hydrogen plasma pre-treatment and SiNW growth. The results show that the plasma treatment induces a coalescence of the Cu-rich cores of the NPs and the SiNW growth process induces a phase transformation of the catalyst cores.

Summary: In this study, a graphene oxide (GO)/nickel-doped iron oxyhydroxide (Ni:FeOOH)/silicon nanowires (SiNWs) photocatalyst was designed and fabricated to enhance the hydroxyl radical (•OH) production rate in the UV/hydrogen peroxide (H2O2) system. The photocatalyst combines the advantages of SiNWs' large surface area and light absorption characteristics with the heterogeneous photo-Fenton active Ni:FeOOH and photocatalytically active/charge separator GO. The built-in electric field of GO/Ni:FeOOH/SiNWs promotes the separation of electrons and holes, resulting in improved photocatalytic performance. Our photocatalyst achieves a 5.7-fold increase in •OH yield compared to the blank H2O2 solution sample and expands the light absorption spectrum to include visible light irradiation.

Summary: Since its discovery in 1982, oxidative coupling of methane (OCM) has been considered a promising method for synthesizing ethylene. In this study, undoped neodymium oxide and neodymium oxide doped with different levels of strontium were tested under various operating conditions. The results showed that the catalysts achieved C2+ yields greater than 18%, with the space velocity impacting C2+ selectivity. The difference in activity between the catalysts was attributed to the contribution of different oxygen centers.

Summary: Catalyst-facilitated amine regeneration provides an energy-efficient and economically feasible CO2 capture process. Glucose-derived carbon sphere nanocatalysts with isethionic acid functionalization were developed to optimize the CO2 desorption rate of CO2-loaded monoethanolamine solutions. The synthesized catalysts accelerated the CO2 desorption rate by up to 108% and reduced the heat duty by approximately 10.8% compared to traditional uncatalyzed regeneration. These catalysts can be separated easily, stable in cyclic uses, and suitable for industrial-scale applications. Regenerating solvents with catalysts at 86°C allows the use of low-grade industrial waste heat, enabling efficient CO2 capture facilities to be installed at various industrial sites for achieving net zero emissions by 2050.
