Gamma-ray attenuation coefficients in bismuth borate glasses
Kulwant Singh,Harvinder Singh,Vishal Sharma,R. Nathuram,Atul Khanna,Rajesh Kumar,S. S. Bhatti,H. S. Sahota +7 more
TL;DR: In this article, the attenuation coefficients of glasses in the system were determined at 356, 662, 1173 and 1332 keV photon energies using a narrow beam transmission method.
Journal ArticleDOI
Structural investigation of bismuth borate glasses and crystalline phases
Anu Bajaj,Atul Khanna,Banghao Chen,James G. Longstaffe,U-Werner Zwanziger,Josef W. Zwanziger,Yolanda Gómez,Fernando González +7 more
TL;DR: In this article, bismuth borate glasses were prepared by devitrification of glasses and characterized by X-ray diffraction, FTIR and 11B MAS-NMR studies, showing that the fraction of tetrahedrally coordinated borons (N4) is maximum at 42 −mol% of Bi2O3 and that there is a local maxima in N4 at Bi 2O3 concentration of 50 −mol%.
Journal ArticleDOI
CuO-doped SnO2 thin films as hydrogen sulfide gas sensor
TL;DR: In this paper, the growth and characterization of CuO-doped SnO2 thin films by a thermal evaporation technique was reported, which showed an extremely high sensitivity of ∼106 to few parts per million levels of H2S gas in air.
Journal ArticleDOI
Structure-property correlations in TiO 2 -Bi 2 O 3 -B 2 O 3 -TeO 2 glasses
Nupur Gupta,Amandeep Kaur,Atul Khanna,Fernando González,Carmen Pesquera,Reni Iordanova,Banghao Chen +6 more
TL;DR: In this paper, the structure-property correlations were carried out by density measurements, X-ray diffraction, Differential Scanning Calorimetry (DSC), Raman, FTIR, UV-visible and 11 B MAS-NMR studies.
Journal ArticleDOI
Gamma-ray shielding properties of CaO-SrO-B2O3 glasses
Kulwant Singh,Harvinder Singh,Gopi Sharma,Leif Gerward,Atul Khanna,Rajesh Kumar,R. Nathuram,H. S. Sahota +7 more
TL;DR: In this paper, the mass attenuation coefficients, effective atomic numbers and effective electron densities have been determined experimentally for the glass system x CaO·(0.3)-x )SrO·0.7B 2 O 3 at photon energies 511, 662, 1173, and 1332 kV.
