Kinetic models of swelling and thermal stability of silver/poly(vinyl alcohol)/chitosan/graphene hydrogels
(Journal of Industrial and Engineering Chemistry, 2019)
Silver nanoparticles (AgNPs) were synthesized by in situ electrochemical reduction of Ag+ ions in poly(vinyl alcohol)/chitosan/graphene (PVA/CHI/Gr) hydrogel matrices with different concentrations of chitosan. The ...
Eu3+-Activated Sr3ZnTa2O9 single-component white light phosphors: emission intensity enhancement and color rendering improvement
(Journal of Materials Chemistry C, 2019)
Single-component white light phosphors with a broad and full color spectrum are urgently required to overcome residual problems with commercial phosphors. In this paper, we describe how Eu3+, as the dopant of Sr3ZnTa2O9 ...
The influence of gamma irradiation on the color change of wool, linen, silk, and cotton fabrics used in cultural heritage artifacts
(Radiation Physics and Chemistry, 2019)
Fabrics made of wool, linen, silk, and cotton, which are used in the making of artifacts of cultural heritage, were divided into three groups. The first group wasn't dyed, the second group was dyed with natural dye (using ...
Photoluminescence properties and thermal stability of RE2-xEuxSn2O7 (RE = Y3+, Gd3+, Lu3+) red nanophosphors: An experimental and theoretical study
(Powder Technology, 2019)
Defect-fluorite structured Eu 3+ -doped Y 2 Sn 2 O 7 nanoparticles (30–40 nm) were successfully prepared through a facile co-precipitation method without any organic additives or templates followed by calcination in air. ...
