On the positron annihilation spectroscopy and tensile behavior of COOH-MWCNT/epoxy nanocomposites [PDF]

Journal of Particle Science and Technology
Positron Annihilation Lifetime Spectroscopy (PALS) is sensitive to the material voids/free volume on the atomic scale. For this reason, this method has been used as a unique technology to measure the free volume and structural defects in polymers in ...

Positron annihilation spectroscopy to study nanoprecipitations in aluminium alloys

, 2022
S.54-62Positron Annihilation Spectroscopy has been used to study the microstructure in aluminum alloy AA7075-T6 after RRA (retrogression and re-aging) heat treatment. Nano-precipitates act as traps for thermalised positrons.

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.
