Evaluation of the role of superoxide radical as chain carrier for the formation of hydroxyl radical during ozonation

Urs von Gunten, Gang Yu

Superoxide radicals (O-2(center dot-)) have been suggested as an important chain carrier in the radical chain reaction that promotes ozone (O-3) decomposition to hydroxyl radicals ((OH)-O-center dot) during ozonation. However, due to the difficulty in meas ...

Periodate activation with copper oxide nanomaterials for the degradation of ciprofloxacin- A new insight into the efficiency and mechanisms

Shaoxian Li

In this study, CuO was synthesized using a facile precipitation method and was characterized using various techniques for the efficient activation of periodate (PI). Compared to systems consisting of PI alone (0.5 mM) and CuO alone (0.5 g/L), the CuO (0.5 ...

Strategies for energy-efficient frontal polymerisation processing and microstructural evaluation of fibre reinforced composites

Jacobus Gerardus Rudolph Staal

Liquid composite moulding methods are widely applied for manufacturing of fibre reinforced polymer (FRP) composites and consist of two main stages: impregnation of fibrous reinforcements by a liquid monomer resin and curing of this resin. This thesis work ...

Oxidase-Type C-H/C-H Coupling Using an Isoquinoline-Derived Organic Photocatalyst

Xile Hu, Lei Zhang

Oxidase-type oxidation is an attractive strategy in organic synthesis due to the use of O-2 as the terminal oxidant. Organic photocatalysis can effect metal-free oxidase chemistry. Nevertheless, current methods are limited in reaction scope, possibly due t ...

Enhancement of Pressure-Sensitive Adhesive by CO2 Laser Treatment

Dario Floreano, Jun Shintake, Yegor Piskarev, Vivek Ramachandran

Pressure-sensitive adhesives (PSAs) are polymeric films that can be adhered to and detached from surfaces without leaving residue. Researchers are looking to enhance the bond strength between PSAs and different substrates. It can be achieved by tuning PSA' ...
