Coronavirus disease-2019 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the most difficult recent global outbreak. Semiconducting materials can be used as effective photocatalysts in photoactive technology generating various reactive oxidative species (ROS), including superoxide (•O2−) hydroxyl (•OH) radicals, either degradation of proteins, DNA, RNA or inhibition cell development through terminating cellular membrane. This review emphasizes capability...
A novel H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> sensor using tapered optical fiber coated with Pd/ZnO nanostructures have been developed. The ZnO was synthesized and deposited onto via chemical bath deposition (CBD) method. characterized by FESEM, XRD EDX to confirm the material properties. It discovered that is sensitive towards different concentrations of in synthetic air at 180° C operating temperature. By varying time...
The vanadium (V) and nitrogen (N) dopants on TiO₂ demonstrated superior photocatalytic performance for the degradation of methylene blue (MB) dye under visible light. vanadium, V, N-co-doped was synthesized by a modified sol-gel method. It revealed that V N codoping had significant effect band gap (Eg) TiO₂, where pristine possessed wide (3.18 eV) compared to V-doped (2.89 N-doped (2.87 while depicted narrowest (2.65 eV). greatly increased specific surface area (103.87 m²/g) as P25 (51.68...
The performance of hybrid fillers between rice husk and sawdust filled recycled high density polyethylene (rHDPE) with the presence antioxidants (IRGANOX 1010 IRGAFOS 169, ratio 1 : 1) was investigated. biocomposites 30 wt% matrix around 70 (rice sawdust) different antioxidants’ contents (0 to 0.7 wt%) were prepared single screw extruder. Increasing amount in reduced modulus elasticity rupture on flexural testing. addition increased tensile impact strength biocomposites. From study, samples...
Recently, research on natural fiber reinforced polymer composites has gained importance due to the abundant sources of fibers that can be obtained at very low cost. In this study, wood plastic composite (WPC) materials is made by mixing (compounding) high density polyethylene (HDPE) and (ligno) cellulose fiber, i.e. rice husk with sawdust have been manufactured using a volume process counter rotating twin screw extruder. Different fire retardant agents employed in order improve behavior...
This study focuses on fabricating manganese dioxide/zinc oxide (MnO2/ZnO) thin films using a two-stage chemical bath deposition (CBD) technique. The concentration effect of MnO2 film for the second stage will be optimised and selected based their thermal conductivity behaviour. It was found out that wettability showed an increase in contact angle (CA) after addition ZnO, with highest CA 14.5°C 12% ZnO. same sample also demonstrated commendable performance reaching constant temperature 35.9°C...
Abstract Besides so many great potentials of hydrogen (H 2 ) applications, such as primary reagent used for the industrial chemical processes and a potential clean energy source in future, handling it can cause hazardous situations due to its highly flammable explosive nature. Therefore, leakage detection is crucial control reaction process running smoothly, thereby ensure manufacturing safety routine life. For this reason, paper will be reported on tapered optical fiber coated with Pd/ZnO...
In this work, chemical bath deposition (CBD) method is used to form zinc oxide (ZnO) thin film nanostructures. Three types of (Zn) precursors, namely Zn (NO 3 ) 2 , ZnSO 4 and ZnCl were the time in water controlled for 20, 40 60 minutes at 85 °C respectively. The effect seed layer, by using potassium permanganate (KMnO solution, on formation films glass substrates has been determined. It was found that presence layer promote better adhesion which allows ZnO with a higher growth rate...
In this study, zinc oxide (ZnO) structured films were grown on glass substrates using a simple chemical bath deposition (CBD) method with different salt precursors. The variation of precursors towards the surface morphology thin and its wettability properties investigated. Four types (Zn) used as are chloride (ZnCl2), acetate (ZnAc2), nitrate (Zn(NO3)2) sulfate (ZnSO4). crystallinity ZnO was evaluated X-ray diffraction (XRD), observed field emission scanning microscopy (FESEM). Finally,...
