Vanadium pentoxide thin films have been deposited on quartz substrates via sol-gel synthesis and dip coating. The process was developed to establish a reliable and inexpensive method to produce thin films with a high temperature coefficient of resistance (TCR) for sensing applications. Sol-gel p...

Vanadium pentoxide is considered as a candidate of cathode material for lithium-ion batteries owing to its high specific capacity, large potential window, and short diffusion pathway. However, vanadium pentoxide has its own limitations such as insufficient electronic conductivity, sluggish ion d...

The high temperature oxidation behavior of V and V-4Ti-(1–7) Ta alloys was investigated under air atmosphere in the temperature range from 250 to 750 °C using isothermal oxidation testing. The oxidized samples were characterized with Grazing incidence X-ray diffraction (GIXRD), scanning electr...

Sensors with silicon substrates are limited in their application at higher temperatures than 250 °C due to the small band gap energy in silicon. In this study, a hydrogen gas sensor with metal-oxide-semiconductor (MOS) structure capable of operating at high temperatures above 300 °C is investi...

Antimony–doped tin oxide–coated TiO2 (TiO2@SbxSn1-xO2 or TiO2@ATO) composite was fabricated by a facile polymeric precursor (Pechini) method, with the percent yield up to 90%. Different doping amount of antimony was used to investigate the effect on conductivity of the TiO2@ATO composite. Vari...

A novel voltammetric platform has been developed with nanoparticles of antimony oxide (Sb2O3NPs) and multiwalled carbon nanotubes (MWCNTs).

Zinc (Zn) is an important micronutrient in the ocean, and fixation of Zn into organic, trace element-rich sediments is an important contributor to Zn cycling in the ocean. Framboidal sulfides are considered to be the major host for Zn in such settings. The sequestration of Zn into framboids via ...

The study focused on the qualities of spray-formed Silver-doped Zinc sulphide (ZnS) thin films sprayed on soda-lime glass (slg) substrate. Silver-doped and undoped ZnS thin films with 0%, 1%, 3% and 5% Silver concentrations were deposited. The qualities of the synthesized films were investigated...

In spite of extraordinary properties of zinc sulphide nanoparticle (nZnS), its role on plant system is not well understood, yet.
