Laser‐Synthesized Carbon‐Coated Elemental Bismuth Nanoparticles for Sustained Reactive Oxygen Species Generation Under Visible‐Light Irradiation

Small, EarlyView.
Femtosecond laser ablation of bismuth in acetone yields carbon‐coated nanoparticles with a metallic Bi0 core and an amorphous carbon shell. The core‐shell architecture preserves visible‐light‐driven redox activity and enables sustained hydroxyl‐radical generation.

Fluorinated copolymer resists for high‐resolution negative‐tone lithography: Preparation and patterning performance

Smart Molecules, EarlyView.
Electron‐beam induced C–F cleavage in –CF3 generates F−, which abstracts a proton to form the acid that catalyzes tBMA deprotection during post‐exposure baking. This self‐sensitization mechanism enables the precise formation of high‐resolution negative‐tone patterns with enhanced sensitivity and resolution.

Optical design of beam for proton therapy energy selection system based on CYCIAE-230 superconducting cyclotron

He jishu
BackgroundThe energy selection system (ESS) is a key part of the cyclotron-based proton therapy facility. In addition to regulating the energy of the fixed-energy proton beam generated by the cyclotron to match the depth of the tumor, the other main role

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments

Smart Molecules, EarlyView.
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.
