AI Article Synopsis

  • A simple two-step method created stable, water-dispersible polymer nanocapsules (M@CB-PNs) decorated with metal nanoparticles (M=Pd, Au, and Pt) using cucurbit[6]uril (CB[6]) and metal salts.
  • The polymer nanocapsules provide a platform for introducing and stabilizing various metal nanoparticles, allowing for controlled sizes and new nanostructures.
  • Palladium nanoparticles demonstrate high stability in water and excellent catalytic performance in forming carbon-carbon and carbon-nitrogen bonds, showing promise for eco-friendly catalyst applications.

Article Abstract

A facile synthesis of highly stable, water-dispersible metal-nanoparticle-decorated polymer nanocapsules (M@CB-PNs: M=Pd, Au, and Pt) was achieved by a simple two-step process employing a polymer nanocapsule (CB-PN) made of cucurbit[6]uril (CB[6]) and metal salts. The CB-PN serves as a versatile platform where various metal nanoparticles with a controlled size can be introduced on the surface and stabilized to prepare new water-dispersible nanostructures useful for many applications. The Pd nanoparticles on CB-PN exhibit high stability and dispersibility in water as well as excellent catalytic activity and recyclability in carbon-carbon and carbon-nitrogen bond-forming reactions in aqueous medium suggesting potential applications as a green catalyst.

Lenacapavir (LEN) is a highly potent, long-acting antiretroviral medication for treating people infected with muti-drug-resistant HIV-1 phenotypes. The inhibitor targets multifaceted functions of the viral capsid protein (CA) during HIV-1 replication. Previous studies have mainly focused on elucidating LEN's mode of action during viral ingress.

Sedentism is an adaptive alternative in human societies which is often associated with the emergence of complex societies in the Holocene. To elucidate the factors and processes of the emergence of sedentary societies, continuous accumulation of case studies based on robust evidence from across the world is required. Given abundant archaeological and geological evidence from the late Pleistocene to early Holocene, Tanegashima Island, situated in the southern Japanese Archipelago of the northwestern Pacific Rim, has significant potential to unravel factors and processes of sedentism.

Lithium-sulfur (Li-S) batteries face significant challenges, such as polysulfide dissolution, sluggish reaction kinetics, and lithium anode corrosion, hindering their practical application. Herein, we report a highly effective approach using a zinc phosphide (ZnP) bifunctional catalyst to address these issues. The ZnP catalyst effectively anchors lithium polysulfides (LiPSs), catalytically reactivates them, and enhances lithium-ion diffusion.
