Speciation of complex mixtures trace explosives presents a formidable challenge for sensors that rely on chemoselective interfaces due to the unspecific nature weak intermolecular interactions. Nanomechanical infrared (IR) spectroscopy provides higher selectivity in molecular detection without using by measuring photothermal effect adsorbed molecules thermally sensitive microcantilever. In addition, unlike conventional IR spectroscopy, sensitivity is drastically enhanced increasing laser...
In traditional infusion processes, issues such as untimely medication replacement and patients' difficulty in continuously monitoring their levels are prevalent. This study presents the design of a smart automatic device aimed at automating management through three key modules: high-precision liquid level monitoring, automated replacement, control system. By real time, system eliminates need for patients to constantly check levels, accurately controlling amount dispensed transmitting signals...
Abstract As materials science continues to advance, accurately predicting and controlling the effects of microscopic defects on macroscopic mechanical properties has become a crucial research area. Traditional experimental methods currently face challenges in providing precise characterization at scale, particularly regarding accurate definition quantification geometric parameters associated with micro-bubble defects. Consequently, there is an insufficient understanding their material...

Abstract By using a combination of rotational spectroscopy and ab initio calculations, an unusual H‐bond topology was revealed for the 2‐fluoroethanol trimer. The trimer exhibits strong heterochiral preference adopts open OH⋅⋅⋅OH while utilizing two types bifurcated H‐bonds involving organic fluorine. This is in stark contrast to cyclic adopted by trimers water other simple alcohols. strengths different were analyzed quantum theory atoms molecules. study showcases remarkable example...
Centrally staged swirl combustion can effectively reduce NOx emission. However, the complex field is susceptible to producing large-scale coherent structures, such as precessing vortex core and central (CVC). This study mainly investigates effect of CVC on flow flame in a centrally spray combustor at elevated temperature pressure using 10 kHz high-speed CH* chemiluminescence (CL), 20 particle image velocimetry, CH2O planar laser-induced fluorescence (PLIF). For pilot flame, both CL PLIF are...
