The Dynamical Behavior of the s-Trioxane Radical Cation—A Low-Temperature EPR and Theoretical Study

open access: yesMolecules, 2014
The radical cation of s-trioxane, radiolytically generated in a freon (CF3CCl3) matrix, was studied in the 10–140 K temperature region. Reversible changes of the EPR spectra were observed, arising from both ring puckering and ring inversion through the ...

Physical-Mechanical Properties of Superhard Nanocomposite Coatings on Base Zr-Ti-Si-N

open access: yesMedžiagotyra, 2013
Hard and super hard coatings of Zr-Ti-Si-N of from 2.8 μm to 3.5 μm thickness were fabricated using a vacuum arc source with high frequency stimulation. The samples were annealed in vacuum and in air at 1200 °C. It was found that films with a high Zr and

The Toxic Truth About Carbon Nanotubes in Water Purification: a Perspective View

open access: yesNanoscale Research Letters, 2018
Without nanosafety guidelines, the long-term sustainability of carbon nanotubes (CNTs) for water purifications is questionable. Current risk measurements of CNTs are overshadowed by uncertainties.

Biochips: Focusing on Surfaces and Surface Modification

open access: yes, 2004
Thousands of genes and their products (i.e., proteins) in a given living organism function in a complicated and orchestrated way that creates the mystery of life. In “genomics”, briefly genes of organisms, their functions and activities are investigated.
