Incorporation of reduced graphene oxide (rGO) modifies the properties semiconducting metal nanoparticles and makes it possible to tune surface area pore size optimum values, which in turn improves their gas sensing properties. In this work, improve ammonia (NH3) characteristics, was incorporated into tungsten (WO3) nanospheres using a simple ultrasonication method. The rGO-WO3 nanocomposites exhibited porous nanosheets with nanospherical WO3 as observed field-emission scanning electron...
Despite the high sensitivity and selectivity, operating temperature required for activation energy of tin oxide (SnO2) still stands as a drawback SnO2 based gas sensors. In this work, thin films were deposited through spray pyrolysis subjected to sensing at 27 °C (room temperature) towards different gases. The exhibited consistently low response approximately 1 when tested various VOCs. type, concentration, mobility charge carriers determined from Hall measurements. carrier concentration...
Abstract Magnetron‐sputtered Al 2 O 3 thin films were annealed in ambient air. The phase compositions of the as‐deposited (i) fully amorphous, (ii) nanocrystalline γ ‐Al an amorphous matrix, and (iii) crystalline . For all samples, annealing to 1 100–1 150 °C resulted a transformation α ‐alumina. paths depend on fraction films. with low initial fraction, intermediate θ appeared range 000–1 100 °C. predominantly no phases observed, indicating direct ‐to‐ at ∼1
Single-step growth of V<sub>2</sub>O<sub>3</sub> nanosheets on glass substrates has been established for room-temperature ammonia sensing.
Trimethylamine (TMA) is highly toxic and can have lethal effects on living organisms. Detecting the presence of TMA in air very important because, if level exceeds OSHA (Occupational Safety Health Administration) limit, it may harm environment endanger human life. Doping an appropriate flexible way to change electrical structures metal oxide semiconductors (MOSs) improve their ability detect gases. In this work, Mn-doped zinc ferrite thin film nanorods with agglomerated morphology were...
n-Type Mg3Sb2-based thermoelectric materials have recently garnered significant interest due to their superior efficiency. Yet, the advancement of p-type Mg3Sb2 for applications is impeded by its lower dimensionless figure merit (zT). In this study, we demonstrate improved performance through strategic optimization Zn content and Ag doping on Mg/Zn(2) site. Initially, samples Mg3-xZnxSb2 (x = 0, 0.5, 1.0, 1.5) were synthesized via elemental reactions within a Pyrex tube, followed...
