Background of the study
In the so-called advanced oxidation processes (AOP) and in water
treatment by ionizing radiation, which belongs to the class of AOP’s,
too, the main goal is to destroy, or at least to deactivate harmful
water contaminants: pharmaceuticals, pesticides, surfactants,
health-care products, etc. The chemical transformations are suggested
to be initiated by hydroxyl...

RADIATION TECHNOLOGIES FOR MEASUREMENT
Oral
Abstract
The world’s oceans contain more than 4.5 billion tons of uranium; however access to this resource is limited by the ability to extract uranium from seawater efficiently. Lacing fabric substrates with chemical functionalities specific for uranium adsorption is one approach to meeting this challenge. Advanced adsorbent materials are being developed using polymeric substrates with...

Furthering our knowledge on the reactivity of short-lived species in irradiated water at ultrafast timescales is necessary to understand the competitive reactions occurring within the first ps. The composition of aqueous solutions and the water/solid interface can potentially favour or inhibit one of these competitive ultrafast processes, such as electron hydration, electron hole...

Etched ion-tracks membranes are well-known and commercially available membranes for filtration and, in the past decades, have attracted a huge interest for applications in life sciences. More recently, since these membranes serve as template for nanowires or nanotubes fabrication, applications in microelectronics (eg. MRAM for computers) have also been widely investigated. Control over the...

Radicals are part of the chemistry of life. The ever-increasing knowledge of the involvement of radicals in diverse pathological processes has expanded the search for more efficient antioxidants that can diminish radical-induced damage.Stable nitroxide radicals are receiving increased attention as potential therapeutic agents because of their pronounced antioxidative activity, low toxicity,...

The biological effect of ionizing radiation may be rather strongly influenced by the presence of other substances in corresponding medium during irradiation; see the problem of oxygen effect in tumor radiotherapy (at lower LET values). The radicals HO2 arising in diffusing radical clusters formed mainly by densely ionizing ends of secondary electrons are responsible for the enhanced effect in...

RADIATION SYNTHESIS AND MODIFICATION OF MATERIALS
Oral
Silicate glass was considered as suitable material for dosimetric purposes, and the study of stable paramagnetic centers induced by radiation has proven its potential for radiation dosimetry. Despite its several advantages that make it especially attractive, silicate presents some disadvantages like heterogeneity of chemical composition and high melting temperature. These problems can be...
