In this work, nitrogen dioxide (NO2) gas sensors based on zinc oxide nanorods (ZnO NRs) decorated with gold nanoparticles (Au NPs) working under visible-light illumination with different wavelengths at room temperature are presented. The contribution of localized surface plasmon resonant (LSPR) by Au NPs attached to the ZnO NRs is demonstrated. According to our results, the presence of LSPR not only extends the functionality of ZnO NRs towards lo...

Zirconium carbide (ZrC) and hafnium carbide (HfC) have been identified as ultrahigh temperature ceramics with excellent thermal conductivity performance. The temperature profiles of ZrC and HfC have been studied; however, the temperature-dependent of solid solution of (Zr0.5Hf0.5)C is still lacking. Herein, we report the temperature-dependent elastic and thermodynamic properties of (Zr0.5Hf0.5)C using first-principles calculations. The covalent c...

Facile application of carbon derived from natural resources and its composites with transition metal oxides for energy storage has attracted great interest. The synthesis procedure of these hybrid composites is complicated and requires various toxic chemicals. To address the above issues in the present investigation, we synthesized mentha aquatica (MA) biowaste-derived graphitic carbon titanium dioxide (TMGCs) composite through a facile...

The PAN/TiO2/Ag nanofibers membrane for air filtration media was successfully synthesized with electrospinning method. The morphology, size, and element percentage of the nanofiber were characterized by a scanning electron microscopy–energy dispersive spectroscopy, while X-ray fluorescence and FTIR were used to observe the chemical composition. The water contact angle and UV–vis absorption were measured for physical properties. Perfor...

Alzheimer's disease is a neurodegenerative disorder caused by several factors, namely neuroinflammation, neuronal apoptosis, and low levels of neurotransmitter Acetylcholine. MAPK14, TNF-α, IL-1β, and NF-KB are proteins that are directly involved in the neuroinflammatory signaling pathway. Caspase3 is involved in neuronal apoptosis, and AChE act as a neurotransmitter breakdown catalyst. In this study, docking analysis of propolis c...

Electrocatalysis offers a promising alternative to tackle the high demand for the energy consuming and environmentally polluting Haber–Bosch process of industrial ammonia synthesis. Herein, using first-principles calculations based on density functional theory, we successfully predicted that Fe&Ni@Mo2CS2 diatomic catalysts have excellent electrocatalytic nitrogen reduction reaction (eNRR) performance, with a limiting potential of o...

Single-atom catalysts (SACs) have been widely used in heterogeneous catalysis owing to the maximum utilization of metal-active sites with controlled structures and well-defined locations. Upon tailored coordination with nitrogen atom, the metal-nitrogen (M-N)-based SACs have demonstrated interesting physical, optical and electronic properties and have become intense in photocatalysis and electrocatalysis in the past decade. Despite subs...

Two-dimensional hybrid organic-inorganic perovskites (2D-HOIPs) possess intriguing structural properties which makes them promising materials for diverse optical, electronic and scintillation applications. Recently, several classes of hybrid perovskites exhibit potential candidate for radiation detection. However, the scintillation properties of corrugated-type 2D-HOIPs have not been studied so far. In this work, we investigate the scintillation...

Electromagnetic waves show rapid development in electronics, telecommunications, and the military. One of the efforts to overcome the effects of electromagnetic interference is by developing microwave-absorbing materials. Barium hexaferrite is the best candidate for development as an absorber material. Microwave absorption in barium hexaferrite can be increased through Mg-Al doping and reducing the particle size. This study aimed to analyze sonic...
