Optical properties and plasmon – Two different phonons coupling in ZnGeAs2 + Mn
(Journal of Alloys and Compounds, 2013)
Optical properties of p-type Zn1−xMnxGeAs2 for 0 ⩽ x ⩽ 0.078 were investigated by Raman spectroscopy at room temperature. Phonons of ZnGeAs2 are experimentally determined and they are in excellent agreement with those ...
Use of sodium oxalate and calcium formate for chemical activation of high volume fly ash (HVFA) binders
(Elsevier Ltd., 2024)
This study investigates hydration mechanism of a high volume fly ash (HVFA) binder, comprising 70 wt.% of fly ash (FA), chemically activated by using sodium oxalate (Na2C2O4) and calcium formate (Ca(HCOO)2). Prior to the ...

Cerium Oxide Based Nanometric Powders: Synthesis and Characterization
(Science of Sintering, 2007)
Nanometric powders of solid solutions of cerium oxide were obtained by a modified
glycine nitrate procedure. Solid solutions of the host compound CeO2 with one or more
dopants in the lattice were synthesized. Rare earth ...
Supercapacitor electrodes: Is nickel foam the right substrate for active materials?
(MDPI, 2024)
