Novel ozone gas sensor based on ZnO nanostructures grown by the microwave-assisted hydrothermal route
(2016-02-15)
Good quality ZnO nanostructures were obtained by the microwave-assisted hydrothermal synthesis, at low reaction temperatures, using zinc acetate as the starting precursor. X-ray diffraction confirmed the crystallinity of ...
Voltammetric sensor for amoxicillin determination in human urine using polyglutamic acid/glutaraldehyde film
(Elsevier B.V. Sa, 2008-08-12)
A voltammetric sensor for determination of amoxicillin (AMX) was developed based on a glutaraldehyde cross-linked polyglutamic acid modified glassy carbon electrode. The proposed method is based on pre-concentration of AMX ...
Structural and properties of nanocrystalline WO3/TiO2-based humidity sensors elements prepared by high energy activation
(Elsevier B.V. Sa, 2011-10-20)
Nanocrystalline WO3/TiO2-based powders have been prepared by the high energy activation method with WO3 concentration ranging from 1 to 10 molt The samples were thermal treated in a microwave oven at 600 C for 20 min and ...

Gas sensor properties of Ag- and Pd-decorated SnO micro-disks to NO2, H-2 and CO: Catalyst enhanced sensor response and selectivity
(Elsevier B.V., 2017-02-01)
The gas sensor response of tin monoxide micro-disks, functionalized with noble metal nanoparticles (Pd and Ag), to NO2, H-2 and CO were studied by monitoring changes in their resistance upon exposure to the various gases. ...

Development of an electrochemical sensor for determination of dissolved oxygen by nickel-salen polymeric film modified electrode
(Elsevier B.V. Sa, 2012-12-01)
An amperometric oxygen sensor based on a polymeric nickel-salen (salen = N,N'-ethylene bis(salicylideneiminato)) film coated platinum electrode was developed. The sensor was constructed by electropolymerization of nickel-salen ...
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 ...
A new biomimetic sensor based on molecularly imprinted polymers for highly sensitive and selective determination of hexazinone herbicide
(2014)
A new selective sensor based on molecularly imprinted polymers (MIPs) was developed for the determination of hexazinone (HXZ) in environmental samples. MIPs were synthesized using a non-covalent approach, and selection of ...
