Article Synopsis
- Ricin is highly toxic and poses a bioweapon threat, necessitating the development of effective antidotes; this study focuses on a graphene oxide-based nanotechnology called ARMAN as a potential solution.
- ARMAN is created using high-affinity aptamers targeting ricin, demonstrating improved neutralization capabilities and increased cell viability in various cell lines, as well as extending the survival of ricin-poisoned mice in vivo.
- The study indicates that ARMAN could serve as a rapid-response antidote with notable advantages in binding affinity, stability, and therapeutic efficacy, suitable for emergency use in both military and civilian contexts.
Electrochemical semihydrogenation (ESH) of alkynes to alkenes is an appealing technique for producing pharmaceutical precursors and polymer monomers, while also preventing catalyst poisoning by alkyne impurities. Cu is recognized as a cost-effective and highly selective catalyst for ESH, whereas its activity is somewhat limited. Here, from a mechanistic standpoint, we hypothesize that electron-deficient Cu can enhance ESH activity by promoting the rate-determining step of alkene desorption.

- A new hybrid nanostructure inspired by transformation optics is proposed to enhance plasmonic photocatalysis, focusing on improving light harvesting at the site of chemical reactions.
- This novel structure, made from CuZnSnS and Au-Au clusters, demonstrates significant photocatalytic improvements through a combination of templating and seeded growth techniques.
- Experimental results indicate that the design's sharpness and positioning are crucial, with the hybrid nanostructure achieving up to a 9-fold increase in hydrogen production compared to standard CZTS.
