Homodisperse doped polyoxotitanate nanoclusters with formulae Ti11 (MX)O14 (OiPr)17 (M=Mn, Fe or Co; X=Cl, Br I, OiPr=isopropoxide) display strongly dopant-dependent properties. Spectroscopic solution and reflectance measurements backed up by density of states time-dependent DFT calculations based on the determined structures, show prominent effect FeX substitution decreasing HOMO-LUMO gap particles. The is attributed to presence an occupied β orbital halfway bandgap, leading long-wavelength...
Abstract Fluorescence intensity ratio (FIR) thermometry has been regarded as new optical because of its faster response, higher sensitivity, and accuracy. However, improving the sensitivity is still a challenge. Here, Ba 2 LuNbO 6 :Er 3+ ,Yb up‐conversion specimens were synthesized, characterized, designed for dual‐mode based on FIR. The H 11/2 / 4 S 3/2 thermally coupled energy levels (TCELs) F 9/2 non‐TCELs (NTCELs) Er selected two FIR modes thermometry. gap TCELs in phosphors was...
Abstract In this work, a series of carbon nanotubes filled polypropylene (PP/CNT) and polyamide 6 (PA6/CNT) composites were prepared by melt blending subsequently molded compression molding microinjection (μIM), respectively. Electrical conductivity results indicate that the percolation threshold corresponding microparts shifted to higher filler concentrations when compared with counterparts, suggesting prevailing shearing conditions in μIM is unfavorable for construction conductive...
The accuracy of differential interferometric synthetic aperture radar (DInSAR) in monitoring the ground subsidence is a major challenge to be addressed urgently. Using repeat track DInSAR and GIS spatial analysis tools, eight C-band Sentinel-1A SAR images Guotun coal mine (China) were processed determine mining from November 27, 2015 July 24, 2016. data 13 working faces DInSAR- leveling-monitored results compared. A method was proposed solve problem time inconsistency between results....
Single photon LIDAR exhibits exceptional detection sensitivity and finds extensive applications in long-distance measurement three-dimensional imaging domains. However, it is susceptible to background noise interference, leading a trade-off between scanning efficiency angular resolution, thereby limiting its overall performance. In this paper, we propose novel 'compression-resampling' high-resolution method for single-photon based on the spatial correlation of target scene. This approach...
Abstract The fabrication of perovskite single crystal‐based optoelectronics with improved performance is largely hindered by limited processing techniques. Particularly, the local halide composition manipulation, which dominates bandgap and thus formation heterostructures emission multiple‐wavelength light, realized via prevalent liquid‐ or gas‐phase anion exchange utilization lithography, while monocrystalline nature sacrificed due to polycrystalline transition in massive defects emerging,...
This paper proposes an improved dual-mode fast charger for supercapacitors that utilizes both continuous and fine-tuned pulse currents. By tuning the voltage across output inductor, proposed improves characteristics of conventional forward converter in transitions between currents are much faster. Moreover, removes two switches a similar topology, which leads to simpler more robust control strategy, lower cost. A prototype is built preliminary experimental results demonstrate operation...
The timely and accurate monitoring of wildfires other sudden natural disasters is crucial for safeguarding the safety residents their property. Satellite imagery wildfire offers a unique opportunity to obtain near-real-time disaster information through rapid, large-scale remote sensing mapping. However, existing methods are constrained by temporal spatial limitations imagery, preventing comprehensive fulfillment need high resolution in early warning. To address this gap, we propose...
This paper proposes a dual-mode supercapacitor fast charger employing both continuous and fine-tuned pulse currents based on the fact that can be charged or discharged by large current during limited period of time. By tuning voltage across output inductor, proposed improves characteristics conventional forward converter in transitions between are much faster. Simulation results verify operation show charging time is significantly reduced.
The purpose of this study was to evaluate the clinical efficacy internal fixation with locking compression plates (LCP) in treatment patients extremity fractures and effect on recovery limb function. A total 488 admitted our hospital from June 2019 December 2022 were retrospectively analyzed divided into open reduction (ORIF) group (n = 236) LCP 252) according surgical procedure. Outcome indicators included intraoperative bleeding, operative time, length stay, pain duration, quality life,...
In this paper, we investigated the relationship between ethanol conversion, C4 olefin selectivity, and temperature by establishing a series of mathematical models. Specifically, conversion selectivity to olefins is discussed solving linear regression equations. addition, support vector machine (SVR) model was used describe effect independent variables on rate selectivity. Finally, change catalyst activity.
Upright position CT scans make it possible for full-length-body imaging at conditions more relevant to daily situations, but the substantial weight of upright scanners increases risks floor's stability and patients'safety. Robotic-arm CBCT systems are supposed be a better solution this task, such still face challenges including long scanning time low reconstruction quality. To address above challenges, paper proposes novel method calculate optimal pitch based on data completeness analysis,...
