Positron detection in silica monoliths for miniaturised quality control of PET radiotracers [PDF]
, 2016 We demonstrate the use of the miniaturised Medipix positron sensor for detection of the clinical PET radiotracer, [⁶⁸Ga]gallium-citrate, on a silica-based monolith, towards microfluidic quality control.

Advanced Engineering Materials, EarlyView.We develop a one‐step spray coating approach to coat the fluorinated graphene (FG) nanosheet onto the N95 respirators. The spray‐coated superhydrophobic N95 respirators can effectively repel respiratory droplets off instantaneously and prevent SARS‐CoV‐2 virus accumulation on the surface.

Synthesis of fluorine‐18 labeled 1,1‐difluoro‐2,2‐dichloroethyl aryl ethers by 18 F‐for‐ 19 F exchange [PDF]
, 1990 Fluorine‐18 labeled 1,1‐difluoro‐2,2‐dichloroethyl aryl ethers have been prepared by a facile 18 F‐for‐ 19 F isotopic exchange reaction. The isotopic exchange proceeds in good to excellent yields (up to 85%), and is dependent on reaction time ...

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

Sonochemical Functionalization of Glass
Advanced Functional Materials, EarlyView.A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...
