Data are reported on the triplet states of a series of fluorene-based A-alt-B type alternating copolymers based on pulse radiolysis-energy transfer and flash photolysis experiments. From the pulse radiolysis experiments, spectra are given for eight copolymers involving phenylene, thiophene, benzothiadiazole, and oligothienylenevinylene groups. Quantum yields for triplet-state formation (PhiT) h...
Silver nanoparticles (AgNPs) with broad-spectrum antimicrobial properties are gaining increasing interest in fighting multidrug-resistant bacteria. Herein, we describe the synthesis of AgNPs, stabilized by polyvinyl alcohol (PVA), high purity and homogeneous sizes, using radiolysis. Solvated electrons reducing radicals induced from solvent radiolysis no other chemical agents needed to reduce me...
A solid state radiolysis was conducted to examine the reactivity of amino acids towards high energy dose of gamma radiations. The presence of amino acids in the bulk of meteorites has raised the question of "if" and eventually "how" they could have been important in the development of life on Earth. The presence of radioactive elements in Solar System bodies could have played a crucial role in ...
Conjugated polymers have emerged as very active photocatalysts under visible light. Among these materials, nanostructured polypyrrole (PPy) has recently been used photocatalyst for degradation of environmental pollutants UV well In the present study, we specifically explored photocatalytic activity conducting PPy synthesized by radiolysis, either in water (PPy H2O ) or dichloromethane solvent D...
