In sensor design, electromagnetic field numerical simulation techniques are widely used to investigate the working principles of sensors. These analyses help designers understand how sensors detect and respond external signals during operation. One popular method for computation is meshless radial point interpolation (RPIM), where number distribution nodes critical ensuring both accuracy efficiency. However, traditional RPIM methods often face challenges in achieving stable precise results,...
Developing highly dispersed few stacking layer MoS2 nanocatalysts with high exposure of active sites is still a challenge in improving their catalytic activities. Herein, we report facile strategy for fabricating quasi-single-layer (<3 layers) MoS2/TiO2 by novel one-step hydrothermal method using ammonium tetrathiomolybdate (ATM) and P25 (TiO2) as Mo precursor supporter, respectively. nanosheets on the quasi-single slab less than 10 nm expose maximum anthracene hydrogenation. The results...
In this work, a self-powered synchronous magnetic flux extraction (SP-SMFE) circuit is proposed for electromagnetic energy harvesting. It's bridgeless direct ac-dc converter, that uses large-value external inductor L to store and transfer energy. By comparing the voltage across L, SP-SMFE achieves peak detection of current Iem without an power supply transfers load when reaches value, which can maximize from transducer. Simulation results show output much higher than doubler under range...
Highly active MoS2 catalysts were developed by tuning the precursors and synthesis solvents to upgrade unconventional feedstocks into light fuels through slurry-phase hydrogenation reaction. A highly dispersed quasi-single-layer (QSL) nanocatalyst has been synthesized solvothermal method with l-cysteine ethylene glycol as S precursor solvent, respectively. The QSL demonstrates extremely high selectivity octahydroanthracene of 83.1% percentage 54.0% for catalytic anthracene hydrogenation,...
The paper presents a newly developed high-yield micro-fabrication technology for single-crystalline silicon atomic force microscope (AFM) probes. Both the tips and cantilevers are simultaneously formed by masked–maskless combined anisotropic etching process. Compared to conventional tip-to-cantilever sequential fabrication scheme, this tip-and-cantilever simultaneous formation can effectively increase yield avoiding damaged during following processed photolithographic steps defining...
Microcantilever with integrated piezoresistor has been applied to in situ surface stress measurement the field of biochemical sensors. It is well known that piezoresistive cantilever-based sensors are sensitive ambient temperature changing due highly temperature-dependent effect and mismatch thermal expansion composite materials.

The two-archive 2 algorithm (Two_Arch2) is a many-objective evolutionary for balancing the convergence, diversity, and complexity using diversity archive (DA) convergence (CA). However, individuals in DA are selected based on traditional Pareto dominance which decreases selection pressure high-dimensional problems. even cannot converge due to weak pressure. Meanwhile, Two_Arch2 adopts as output of hard maintain coverage final solutions synchronously increase algorithm. To improve...
