Silicon (Si) dominates the integrated circuit (IC), semiconductor, and microelectronic industries. However, it is a challenge to achieve sub-angstrom surface of Si. Chemical mechanical polishing (CMP) widely used in manufacturing Si, while toxic polluted slurries are usually employed CMP, resulting pollution environment. In this study, novel environmentally friendly CMP was developed, which slurry composed ceria, hydrogen peroxide, sodium pyrophosphate, carboxymethyl cellulose, carbonate,...
Superhydrophobic surfaces have attracted significant attention for their ability to prevent ice formation and facilitate deicing without requiring external energy. However, these are often vulnerable damage from forces, leading functional failure due poor mechanical stability, which limits widespread use. Drawing inspiration the hierarchical groove of rose petals micropapillae lotus leaves, a simple laser-based method is proposed create superhydrophobic surface with micro/nano crater-like...
Ice accretion caused by freezing rain or snowstorms is a common phenomenon in cold climates that seriously threatens the safety and reliability of telecommunication lines other overhead networks. Various anti-icing strategies have been demonstrated through surface engineering to delay ice formation. However, existing surfaces still encounter several challenges; for example, are prone ice-pinning formation due impact supercooled droplets, which leads loss effectiveness. In this study,...
This paper proposes a tunable sensing detector based on Bulk Dirac semimetals (BDS). The bottom-middle-top structure of the is metal-dielectric-Dirac semimetal. designed simulated in frequency domain by finite element method (FEM). And simulation results indicate that achieves three perfect absorption peaks with absorptivity greater than 99.8% range 2.4-5.2 THz. We analyze cause peak using random phase approximation theory. device exhibits good angular insensitivity different incident angle...
Ti and its alloys are widely used in the aerospace, chemical equipment, other fields due to their excellent comprehensive properties. Ti-0.3Mo-0.8Ni (TA10) alloy is a type of near-α with good corrosion resistance. The addition Al element can improve effect solution strengthening alloy, thus, it strength alloy. strength, resistance, heat resistance be further improved by Zr element. Therefore, new Near-α (Ti-0.3Mo-0.8Ni-0.5Al-0.5Zr) was developed basis TA10 enhance mechanical properties In...
Highlights A novel approach of multi-phase jet polishing is proposed using a developed polisher, consisting solid, liquid and gas phases. An abrasive air suggested through customized including solid After polishing, surface roughness Sa decreases from pristine 8.596 to 0.701 0.336 μ m, reduces 92% 96%, respectively. Defect volume unit area achieved by optimized parameters lessens 1/12 that non-optimized ones.
The effects of counter-surface chemistry, relative humidity, and applied normal load on nanowear single-crystalline silicon were studied with atomic force microscopy. In the absence surface can resist mechanical wear as long contact pressure is lower than hardness regardless chemistry (diamond or SiO2) ambient gas type (vacuum, N2, O2, air). these conditions, sliding region protruded forming a hillock. However, when humidity higher ∼7%, hillock formation completely suppressed and, instead,...
The microstructure, mechanical properties, and corrosion resistance of TA10 titanium alloy annealed via different cooling methods were investigated. After annealing, the intergranular β phase decreases, most strip α changes to equiaxed phase. grain size is largest, content primary lowest at longest annealing time. sheet with furnace shows better plasticity than that air cooling. tensile strength Vickers hardness gradually decrease increasing time, elongation increases Different result in...
A near-infrared (NIR) sub-ppm level photoacoustic sensor for hydrogen sulfide (H2S) using a differential Helmholtz resonator (DHR) as the cell (PAC) was presented. The core detection system composed of NIR diode laser with center wavelength 1578.13 nm, an Erbium-doped optical fiber amplifier (EDFA) output power ∼120 mW, and DHR. Finite element simulation software used to analyze influence DHR parameters on resonant frequency acoustic pressure distribution system. Through comparison, volume...
