Assessing nitrogen dioxide (NO2) impact on health preand post-COVID-19 pandemic using IoT in India
(Emerald, 2020)
Purpose - Corona Virus Disease 2019 (COVID-19) is a deadly virus named after severe acute respiratory syndrome coronavirus 2; it affects the respiratory system of the human and sometimes leads to death. The COVID-19 mainly ...
Effect of iron and vanadium on the phase transition of titanium dioxide obtained by polymeric precursor method
(2017-01-01)
The titanium dioxide phase formation is dependent on the synthesis method, temperature of calcination and modifiers insertion. By using chemical methods, such as Polymeric Precursor Method, the organic impurities or extrinsic ...
Enhancement of surface properties of solgel tin dioxide thin films with addition of surfactant in the precursor solution
(2021-07-01)
The use of the Triton X-100 nonionic surfactant in the precursor solution has revealed a fundamental increase on the surface area, which is very relevant for applications as gas sensors and in photocatalysis. Besides, this ...
Direct synthesis of Ru3(BTC)2metal-organic framework on a Ti/TiO2NT platform for improved performance in the photoelectroreduction of CO2
(2021-01-01)
This work describes the use of a thin film of Ru3(BTC)2 metal-organic framework (MOF) deposited onto Ti/TiO2 nanotubes as a photocathode in CO2 reduction. This approach combines the advantages of the ruthenium MOF as a ...
Study of the zirconium and silicon homovalent dopants insertion on the structure and bandgap energy of titanium dioxide powders
(2018-01-01)
The reconstructive transformation occurring during the anatase-to-rutile phase transition can be observed through adequate techniques such as Thermal Analyses and Z-ray diffractometry followed by structural refinement. The ...
Surface Physicochemical and Structural Analysis of Functionalized Titanium Dioxide Films
(2018-06-05)
Titanium and its alloys are recognized as acceptable materials for many applications. The properties of titanium dioxide (TiO2) thin films are directly related to the structural characteristics of the material, which can ...
Structural and thermal studies of titanium dioxide gel modified with anatase isostructural zircon silicate
(2018-01-01)
Important changes in anatase crystal structure are responsible for the consequent anatase-to-rutile phase transition in titanium dioxide powders. In order to investigate several structural rearrangements occurring in anatase ...
Indoor ozone and nitrogen dioxide concentration in two museums of the São Paulo megacity - Brazil

This paper reports and discusses O3 and NO2 concentration data collected
between 2009 and 2011 in the indoor environments of two
important Brazilian museums located in the megalopolis of São Paulo:
the University of São ...
Influence of pH of Colloidal Suspension on the Electrical Conductivity of SnO2 thin Films Deposited Via Sol-Gel-Dip-Coating
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2011-01-01)
Tin dioxide (SnO2) thin films are deposited by the dip-coating technique from colloidal suspensions prepared with distinct pH through the sol-gel method. The decrease of the pH contributes to the destruction of an electrical ...
