Sensing of -butanol vapours using an oxygen vacancy-enriched ZnSnO-SnO hybrid-composite.

The precise identification of various toxic gases is important to prevent health and environmental hazards using cost-effective, efficient, metal oxide-based chemiresistive sensing methods. This study explores the sensing properties of a chemiresistive sensor based on a ZnSnO-SnO microcomposite for detecting -butanol vapours. The microcomposite, enriched with oxygen vacancies, was thoroughly characterized, confirming its structure, crystallinity, morphology and elemental composition.

Graphene-based nanomaterials applications for agricultural and food sector.

In the past decade, graphene-based nanomaterials (GBNs) have been considerably investigated in agriculture due to their exceptionally enriched physicochemical properties. Productivity in the agricultural sector relies significantly on agrochemicals. However, conventional systems suffer from a lack of application efficiency, resulting in environmental pollution and associated problems.

Bright and persistent green emitting MgGaO:Mn for phosphor converted white light emitting diodes.

Narrow band green emitting phosphors have gained widespread attention due to their application in white light emitting diode (wLED) backlight displays. Commercial backlight displays have a broad band green phosphor which limits their performance. In this work, bright, narrow and thermally stable green emitting MgGaO:Mn (MGO-Mn) has been synthesized.
