Real-time monitoring of volatile organic compounds (VOCs) is crucial for both industrial production and daily life. However, the non-reactive nature VOCs their low concentrations pose a significant challenge developing sensors. In this study, we investigated adsorption behaviors typical (C2H4, C2H6, C6H6), on pristine Pt-decorated SnS monolayers using density functional theory (DFT) calculations. Pristine have limited charge transfer long distances to VOC molecules, resulting in...
The efficient and homogeneous mixing of fluids is crucial for microfluidic applications, such as chemical reactions, biological analyses, material synthesis. This study designs a novel micromixer controllable based on photothermal vortices, which are generated from an array linear heat sources excited by laser. performance theoretically investigated using multiphysics-coupled system the finite element method. We reveal interactions between vortices mechanism fluids. provide stable strength...
Monitoring heavy metals helps prevent metal contamination from affecting human health. However, existing monitoring technologies encounter challenges in real-time detection. Using density functional theory and non-equilibrium Green's function method, sensing capacities of SnS monolayer towards are analyzed by adsorption energy, charge transfer, energy band structure, the states, differential density, recovery time, transport performance. monolayers exhibit high selectivity good sensitivity...
A novel equivalent circuit for separate absorption grading charge multiplication (SAGCM) APDs composed of basic components is developed. The model applied to simulate the frequency performance APDs, and simulating results show a well-reasonable agreement with physical calculation experimental data. influence three important factors on performance, including carrier transit time, avalanche buildup parasitic elements (consisted resistance, inductance, capacitance APDs) are investigated. Using...
Optofluidic manipulation of droplets is critical in droplet-based microfluidic systems for chemistry, biology, and medicine. Here, we reported a thermocapillary microvortices-based platform controlling oil-in-water through integrating photothermal waveguide into chip. The sizes shapes the can be controlled by adjusting optical power or positions water-oil interface. teardrop-shaped droplets, which encapsulate accumulate mesoscopic matters easily, were generated when interface channel...
Water-in-oil droplet generation for object encapsulation is of increasing importance in biochemical reaction, drug diagnostics, and environmental science. Optofluidic technique a powerful tool manipulating mesoscopic particles droplets within continuous liquid phase. Here, we report flexible miniaturized generator based on microvortex chip by light-heat energy conversion to fuse, trap, release picoliter aqueous the immiscible carrier oil. The sizes generators can be tuned flow rate vortices....
Microfluidic techniques have emerged as promising strategies for a wide variety of synthetic or biological sorting. Unfortunately, there is still lack sorting with automatic and handy operation. In contrast to passively generated vortices, the thermocapillary vortices produced by temperature gradient advantages flexible manipulation, stable strength, simple integration. this Letter, we present device used pump-free separation particles through interaction without external fluidic control...
Heavy metal pollution has a negative impact on both human health and the environment. The monitoring of heavy is therefore very important from practical standpoint. In this study, adsorption energy, charge transfer, band, densities states, sensitivity SnSe monolayers toward metals (As, Cd, Cr, Hg, Ni, Pb) were investigated using density functional theory combined with non-equilibrium Green's function approach. calculations show that have excellent sensitivities exceeding limit quantitation...
