Abstract Plastic scintillators are commonly used as first‐line detectors for special nuclear materials. Current state‐of‐the‐art plastic based on poly(vinyltoluene) (PVT) matrices containing high loadings (>15.0 wt %) of 2,5‐diphenyloxazole (PPO) offer neutron signal discrimination in gamma radiation background (termed pulse shape discrimination, PSD), however, they suffer from poor mechanical properties. In this work, a series p ‐terphenyl and fluorene derivatives were synthesized tested...
Copper(II) formate is efficiently incorporated into the pores of a 2D imine-based covalent organic framework (COF) via coordination with phenol and imine groups. The coordinated metal ion then reduced to Cu(I) thermal treatment that evolves CO2. After loading hydrogen gas, majority H2 desorbs from coordinatively saturated Cu(II) COF at temperatures < −100 °C. However, activated retains adsorbed above room temperature. Adsorption/desorption was highly reversible. Diffuse reflectance infrared...
Here we prepare Pickering emulsions with semiconductor quantum dots (QDs). Amphiphilic PbS QDs are prepared by constructing Janus-ligand shells comprised of lipophilic oleic acid and hydrophilic 4-(2,2-dicyanovinyl)cinnamic ligands. Upon homogenization, the self-assemble at water–dichloromethane interface, forming stable emulsions. The photocatalytic properties evaluated photodegradation reaction methyl orange (MO) dye molecules. Under same conditions, MO was significantly degraded when...
We have developed a single step palladium-catalyzed Heck coupling of aryl halides with vinyl phosphonic acid to produce functionalized (<italic>E</italic>)-styryl acids.
