Detection of leaks flammable methane (CH4) gas in a timely manner can mitigate health, safety, and environmental risks. Zinc oxide (ZnO), polar semiconductor with controllable surface defects, is promising material for sensing. In this study, Ag-Ru co-doped into self-assembled ZnO nanorod arrays (ZnO NRs) was prepared by one-step hydrothermal method. The sample shows good hydrophobic property as result its particular microstructure, which results high humidity resistance. addition, oxygen...
Despite significant progress, fabricating two-dimensional (2D) lithium niobate (LN)-based photonic crystal (PhC) cavities integrated with tapered and PhC waveguides remains challenging, due to structural imperfections. Notable, especially, are variations in hole radius (r) inclination angle (°), which induce bandgap shifts degrade quality factors (Q-factor). These fabrication errors underscore the critical need address nanoscale tolerances. Here, we systematically investigate impacts of key...
Background: Alopecia areata (AA) remains one of the most challenging afflictions encountered in dermatology clinics. It is characterized by an autoimmune-mediated inflammatory process and around hair follicles, causing reversible, non-scarring loss. With ongoing search for optimal treatment strategies, potentially positive role autologous platelet-rich plasma (PRP) therapy as well minoxidil has been reported various studies; however, comparison two modalities largely underexplored. This...
In this paper, to fully understand the influence of nanofabrication error issues on lithium-niobate-based device, systematic simulations and optimizations photonic crystal (PhC) optomechanical cavity considering material dispersion inclination angle PhC air hole are investigated in details. The structural parameter influences band gap, line defected waveguide transmission characteristics, optical resonant wavelength microcavity, mechanical frequency all discussed. effects simulation methods...
Vitiligo has a special significance to the skin of colour (SOC) population because depigmentation is more obvious in SOC population. As result, vitiligo exerts huge stigma on affected individuals. The literature so far reported health-related quality life (QOL), including dermatology index (DLQI), and demonstrated profound effect patient's QOL. Those by are found have lower self-esteem when compared non-affected impact even graver underrepresented. Thus, objective this study was report mean DLQI
Micro-electromechanical systems (MEMS) technologies allow the reduction of mass and manufacture gyroscopes, which demonstrate features small volume, low consumption power, high trustiness, easy integration with many applications, as a device for measuring angular velocity moving objects. In order to optimize sensing performance, we designed new model micro-gyroscope based on photonic crystal optomechanical cavity. The proposed has following functional features, according modeling results:...
The emergences of silicon-based photonic crystal (PhC) waveguides and two-dimensional (2D) PhC line-defect optical cavities have revolutionized the field integrated photonics. In this paper, we design fabricate a high-quality (high-Q) 2D cavity with waveguides. We employ finite-difference time-domain (FDTD) method to simulate cavity, considering two different thicknesses: 0.5 μm 0.25 μm. By optimizing air-slot widths for waveguides, are able achieve remarkable Q-factors cavity. With silicon...
