Acetaldehyde Adsorption Characteristics of Ag/ACF Composite Prepared by Liquid Phase Plasma Method

open access: yesNanomaterials, 2021
Ag particles were precipitated on an activated carbon fiber (ACF) surface using a liquid phase plasma (LPP) method to prepare a Ag/ACF composite. The efficiency was examined by applying it as an adsorbent in the acetaldehyde adsorption experiment.

A metallic magnetic calorimeter dedicated to the spectrometry of L X-rays emitted by actinides

open access: yesEPJ Web of Conferences, 2017
Many actinides emit intense L X-rays consecutively to their decay. However the intensities of these X-rays are not well known: they are generally calculated with relatively large uncertainties and do not always agree with existing measurements.

Physical investigations on the radiation damage of graphene oxide by IR pulsed laser

open access: yesEPJ Web of Conferences, 2018
Graphene oxide foils were irradiated by Nd:YAG laser at the moderated intensities of the order of 108 W/cm2 in vacuum. Measurements of atomic emission during the laser irradiation were performed with ion collectors and mass spectrometry, demonstrating a ...
