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.

Thermoluminescence behavior of KClXBr1−X: in mixed crystals exposed to gamma radiation [PDF]

open access: yes, 2014
In-doped KClXBr1−X (X=1, 0.75, 0.5, 0.25 and 0) mixed crystal has been grown by the Czochralski method. The segregation coefficient of In was studied by the inductively coupled plasma atomic emission spectrometry (ICP-OES). The crystal structure has been

Synthesis and characterization of polyol stabilised Ag/Co allied nanocomposites [PDF]

open access: yes, 2015
We report the synthesis of polyol stabilized Ag/Co allied bimetallic nanocomposites using the seed growth method involving the successive reduction of metal ions in glycerol (GLY), ethylene glycol (EG) and diethylene glycol (DEG) solutions.

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.

An efficient and heterogeneous Pd-containing modified graphene oxide catalyst for preparation of biaryl compounds

open access: yesHeliyon, 2020
In this research, a novel palladium-containing modified-graphene oxide (GO-N2S2/Pd) catalyst is designed and synthesized for the Suzuki–Miyaura reaction. The prepared catalyst was characterized by different techniques, such as thermogravimetric analysis (
