Comparative gas sensor response of SnO2, SnO and Sn3O4 nanobelts to NO2 and potential interferents
(Elsevier B.V., 2015-03-01)
The gas sensor performance of single crystalline tin oxide nanobelts in different oxidation states (SnO2, SnO and Sn3O4), synthesized by a carbothermal reduction method, is reported. The synthesized materials were characterized ...
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 ...
Speciation analysis of Sn(II) and Sn(IV) using baker's yeast and inductively coupled plasma optical emission spectrometry
(Springer, 2007-03-01)
The use of Saccharomyces cerevisiae as a substrate to selectively retain Sn(II) and Sn(IV) has been investigated. Several factors affecting the retention of the analytes by yeast, such as pH, amount of biomass, temperature ...
