Removal of radioisotopes in solution and bactericidal/bacteriostatic sterilising power in activated carbon and metal silver filters [PDF]
Environmental Toxicology and Pharmacology, 2009 Activated carbon filters play an important role in water filtration and purification from contaminants of different origin. Their limit consists in bacterial proliferation, which may occur only during prolonged periods of non-use and in their ability to remove radioactive contaminants present in waste water from Industry or Nuclear Medicine departments.

Radioisotopes in the study of photosynthetic carbon pathways.
RADIOISOTOPES, 1984 It is a pleasure and a privilege for me to review some of our research over the years on the application of radioisotope tracer methods to the study of carbon metabolism in photosynthesis.

Development and characterization of carbon-bonded carbon fiber insulation for radioisotope space power systems [PDF]
, 1985 The General-Purpose Heat Source (GPHS), an improved radioisotope heat source, employs a unique thermal insulation material, carbon-bonded carbon fiber (CBCF), to protect the fuel capsule and to help achieve the highest possible specific power. The CBCF insulation is made from chopped rayon fiber about 10 ..mu..m in diameter and 250 ..mu..m long, which ...

Novel reverse radioisotope labelling experiment reveals carbon assimilation of marine calcifiers under ocean acidification conditions [PDF]
Methods in Ecology and Evolution, 2020 Abstract Ocean acidification by anthropogenic carbon dioxide emissions is projected to depress metabolic and physiological activity in marine calcifiers. To evaluate the sensitivity of marine organisms against ocean acidification, the assimilation of nutrients into carbonate shells and soft tissues must be examined.

Production of Medical Radioisotopes with High Specific Activity in Photonuclear Reactions with $γ$ Beams of High Intensity and Large Brilliance [PDF]
, 2010 We study the production of radioisotopes for nuclear medicine in $(\gamma,x{\rm n}+y{\rm p})$ photonuclear reactions or ($\gamma,\gamma'$) photoexcitation reactions with high flux [($10^{13}-10^{15}$)$\gamma$/s], small diameter $\sim (100 \, \mu$m$)^2$ and small band width ($\Delta E/E \approx 10^{-3}-10^{-4}$) $\gamma$ beams produced by Compton back ...

The AMS technique as an important tool for the measurement of astrophysical cross sections [PDF]
EPJ Web of Conferences, 2021 Accelerator Mass Spectrometry is a technique commonly used to approach low concentrations of certain long half-life radioisotopes. The most important contribution of the technique is the accurate measure of organic sample ages, by separating masses 12,13
