Ultraviolet diversity of type Ia supernovae
(Oxford University Press, 2016-09)
Ultraviolet (UV) observations of Type Ia supernovae (SNe Ia) probe the outermost layers of
the explosion, and UV spectra of SNe Ia are expected to be extremely sensitive to differences
in progenitor composition and the ...

Palladium-Loaded Hierarchical Flower-like Tin Dioxide Structure as Chemosensor Exhibiting High Ethanol Response in Humid Conditions
(2017-11-23)
The impact of humidity is a crucial factor in the sensing performance of a chemiresistive gas sensor. Therefore, strategies for developing sensors with a small humidity dependence are required. Herein, the volatile organic ...

Study of the selectivity of SnO2 supported membranes prepared by a sol-gel route
(Kluwer Academic Publ, 1998-01-01)
In this work the sol-gel process was used to prepare SnO2 supported membranes with an average pore size of 2.5 nm. The effects of salt concentration (NaCl or CaCl2) and of the pH of the aqueous solutions used on the flux ...
Controlled Synthesis of Layered Sn3O4 Nanobelts by Carbothermal Reduction Method and Their Gas Sensor Properties
(Amer Scientific Publishers, 2014-09-01)
This paper reports both the controlled synthesis of Sn3O4 nanobelts by carbothermal reduction method and the gas sensor properties of these nanostructures. The synthesized material was characterized by X-ray diffraction, ...
Aspects of solid state formation and properties of Sn(0.9)Ti(0.1)O(2) system doped with CoO and Nb(2)O(5)
(J C P D S-int Centre Diffraction Data, 2008-06-01)
The effect of calcination temperature during the formation of the solid solution Sn(0.9)Ti(0.1)O(2) doped with 1.00 mol % CoO and 0.05 mol % Nb(2)O(5) is presented. The structural characteristics of this system were studied ...
