Ultrafast diagnostic technology has caused breakthroughs in fields such as inertial confinement fusion, particle accelerator research, and laser-induced phenomena. As the most widely used tool for ultrafast technology, investigating characteristics of streak cameras imaging process tubes’ complex physical processes is significant its overall development. In this work, a camera modeled simulated using Geant4-based Monte Carlo simulations. Based on selected phosphor screen P43 (Gd2O2S: Tb)...
Lithium cobalt oxide (LCO) is widely used in the 3 C field due to its noteworthy volumetric and gravimetric energy densities. Howbeit, irreversible phase transitions lattice oxygen oxidation may engender during state of deep lithium removal, limiting application high-energy-density batteries. Here, a MgO-coated LCO material (LM1CM2O) with Mg atom-substituted Li Co atoms achieved via rapid solvothermal high-temperature calcination method. The results, ex situ characterizations, DTF...
Due to intriguing electrical and optical properties, two-dimensional MoS2 has gained significant attention emerged as a promising material in photonic optoelectronic fields. Nevertheless, the intrinsic absorption of monolayer is limited visible region only, restricting applications toward near-infrared (NIR) photodetection. Herein, we engineered properties via alloying with Se extend its NIR region, phototransistor was fabricated based on MoS2(1−x)Se2x (x = ∼0.1). When under 780 nm (∼1.59...
ABSTRACT The superabsorbent resin (SAR) containing sodium humate (SH) has been synthesized by free‐radical graft copolymerization with acrylic acid, 2‐acrylamido‐2‐methylpropane sulfonic and SH as monomers in aqueous solution, using N,N ′‐methylenebisacrylamide crosslinking reagent potassium persulfate initiator. structure morphology of the as‐prepared SARs were fully characterized Fourier transform infrared , scanning electron microscopy thermogravimetric analysis, respectively. Meanwhile,...
Abstract Li‐doped ZnO polycrystals with Li 2 CO 3 concentration between 0 and 15 at.% have been prepared using a solid state reaction method. After annealing of the mixed samples at 1200 °C, completely decomposed to O lattice parameters / c first increase up 5 at.%, then decrease increasing concentration. This indicates that atoms prefer interstitial sites low substitute Zn when is beyond certain threshold. Positron annihilation measurements were performed for undoped ‐doped as function...
This abstract describes room temperature ozone sensing using a ZnO based film bulk acoustic resonator (FBAR). The resonant frequency of the FBAR decreased upon exposure due to density increase film. Ozone can be adsorbed on surface by capturing free electrons from film, which increases density. minimum detectable concentration is 21 ppb (parts per billion) with response time 12 s. An analytical model was developed predict relationship between and concentration. In agreement experiment,...
Abstract. This paper analyses a large number of factors related to the influence degree urban waterlogging in depth, and constructs Stack Autoencoder model explore relationship between points’ their surrounding spatial data, which will be used realize comprehensive analysis on work life residents. According data rainstorm 2016 July Wuhan, is validated. The experimental results show that has higher accuracy than traditional linear regression model. Based points distribution information Wuhan...
Point vacancy defects in hexagonal boron nitride (h-BN) were investigated by first-principles calculations based on the generalized gradient approximation method density-functional theory. The obtained formation energies of B (VB) and N (VN) with different charge states suggest that is stable for p-type h-BN both N-rich N-poor growth conditions, while n-type conditions. Positron lifetime also carried out using atomic superposition method. calculated positron bulk was 180.6 ps, VB 183.6 VN...
Positron lifetime spectra have been measured on plastically deformed Zn-doped p-type GaAs with strain ranging from 0 to 15% at room temperature. The were analyzed using PATFIT and MELT programs. Two components observed in samples. second τ2 ∼ 400 450 ps indicated that vacancy clusters formed during deformation. From the temperature behavior of positron samples, detected negative ions as shallow traps, dominant traps attributed acceptor impurity Zn charge. trapping rate was also estimated.
