Light induced phenomena in new polymeric thin films based on aminostyrene

Moldavian Journal of the Physical Sciences, 2006
The light-induced modification of mechanical and optical properties of several amino- styrene-containing polymers has been investigated. The nano- and microindentation techniques were used for determination of mechanical parameters.

Hydrogen-Induced Microstructure Changes in Zr/Nb Nanoscale Multilayer Structures

Metals
Zr/Nb nanoscale multilayer coatings (NMCs) were studied after hydrogenation in a gaseous environment at 400 °C. The hydrogen distribution and content were determined by pressure and hydrogenation time.

Detection of deuterium trapping sites in tungsten by thermal desorption spectroscopy and positron annihilation spectroscopy

Nuclear Materials and Energy, 2016
Thermal desorption spectroscopy (TDS) of tungsten implanted with D2+ ions was performed after irradiation with 8 MeV-electrons, 5.0keV-D2+, and 6.0 MeV-Fe3+. The release peak temperatures of the TDS spectra are discussed.

Influence of oversized atoms X = Ti, Ta, W, Mo on the dynamics of native defects under annealing in Fe35Cr35V20Cu5-(X) HEA studied by positron annihilation spectroscopy (PAS)

Nuclear Engineering and Technology
The dynamics of native defects in the high entropy alloy family produced by arc melting Cu5Cr35Fe35V20X5 (at. %), where X = Ti, Ta, W or Mo corresponds to oversized atoms, were studied using positron annihilation lifetime spectroscopy (PALS) and ...
