CdZnTe (CZT) is a new type of compound semiconductor that has emerged in recent years. Compared to other materials, it possesses an ideal bandgap, high density, and electron mobility, rendering excellent room-temperature composite material for X-ray γ-ray detectors. Due the exceptional performance CZT material, detectors manufactured using exhibit energy resolution, spatial detection efficiency. They also have advantage operating at room temperature. array detectors, furthermore, demonstrate...
Sterilizing high-carbon steel medical surgical blades is crucial for public health and safety. To enhance the sterilization efficiency of blades, we used Monte Carlo simulation method to study effects gamma irradiation parameters on samples. Results show that time required can be decreased 23.14 min or even 6.20 min, significantly shorter than several hours chemical sterilization, by optimizing facility parameters. The source a 1 cm thick 60Co, while reflector 20 cylindrical graphite. five...
Abstract Lead halide perovskites have shown high performance in radiation detection techniques owing to their excellent optoelectronic properties and stability. However, the resistivity of CsPbBr 3 detector is intensively dependent on growth quality single crystal, which closely related temperature gradients or introduction additives. Herein, a crystal with grown based proposed temperature‐concentration balance (TCB) method. The prepared perfect remains repeated experiments, belongs Pnma...
AbstractThe radon adsorption ability of four samples coconut shell-based activated carbons has been investigated by measuring the dynamic coefficient (DAC) each carbon in a room. The findings obtained have shown that DACs are dramatically different even when surface areas near. Nitrogen and X-ray photoelectron spectroscopy analysis used to study microstructure samples. results micropores with diameters between 0.5 0.8 nm play most important role on carbons. Oxygen pore influences because...
The synergetic effects of total ionization dose and high-temperature stress silicon on insulator (SOI) FinFETs (FF) are investigated under ON-state bias condition. experiments TCAD simulations employed to analyze the influence different trapped-charges in gate buried oxide threshold voltage mobility variations current devices. Results show that degradation worsens for n-SOI but weakens p-SOI FinFETs. Also, is significantly enhanced, while change weak effects. induced by both n- p-type SOI...
Iso-molded nuclear graphite (IG-110) was infiltrated with phenol–formaldehyde (PF) resin to get the densified isostatic different bulk density (IG-110-PF, 1.86 g/cm3 and IG-110-PF-D, 1.91 g/cm3). The IG-110-PF IG-110-PF-D samples were irradiated 7 MeV Xe26+ study their surface topography microstructure evolution. impregnation process of PF affects initial graphitization degree graphite, which lead difference in irradiation behavior. Due irradiation-induced graphitization, filler (carbonized...
Community detection has been one of the fundamental problems in network analysis. Results from community (for example, grouping products by latent category) can also serve as information nuggets to other business applications, such product recommendation or taxonomy building. Because several real networks are naturally directed, e.g. World Wide Web, some recent studies proposed algorithms for detecting various types communities a directed network. However, few them considered that nodes play...
Using analysis methods such as Rutherford backscattering Spectrometry, scanning electron microscopy, X-ray diffraction, and Raman spectroscopy, the diffusion behavior of iodine in micro/nano-porous graphite under high-temperature conditions was studied. The results indicate that leads to contraction microcrystals, a decrease interlayer spacing, an increase defect density, resulting reduction microcrystal size. Upon out iodine-loaded graphite, size increases, spacing appears return initial...
The economics and safety of reactors can be affected by the diffusion fission products into graphite. Xenon (Xe) diffusing graphite is most critical neutron absorber poison that slow down or stop chain reaction. transport parameters for inhibiting xenon in are therefore an important scientific problem. Self-sintered nanopore-isotropic (~40 nm) (SSNG) derived from green pitch coke decrease Xe In this study, surface morphology microstructural evolution before after irradiation, as well...
Silicon germanium bipolar CMOS (SiGe BiCMOS) process technology is gaining increasing popularity for RF circuits in wireless applications due to high performance, low cost, yield and higher levels of integration with mixed signal digital circuits. Four test were designed fabricated Conexant's 0.18 /spl mu/m SiGe BiCMOS evaluate the performance benefits provided by this state art technology. The achieved clearly makes a choice future RFIC products.
The chemical corrosion aging of plutonium is a very important topic. It easy to be corroded and produces oxidation products various valence states because its 5f electron orbit between local non-local. On the one hand, phase diagram oxygen complex, so there still not enough research on typical structural phases. other most studies oxide focus PuO2 Pu2O3 with stoichiometric ratio, while understanding non-stoichiometric especially for Pu2O3-x, deep enough. Based this, using DFT + U theoretical...
Abstract As we know radon is harmful to people because of its radioactivity. Focusing on the technical requirements mitigation by adsorption, adsorption behavior carbon nanotube bundles was studied under different diameter tube and spacing using grand cononical ensemble Monte Carlo (GCMC) simulation method. The results show that (10:10) type nanotubes have strongest ability adsorb with a 1 nm, followed (7:7) nm. bundle (8:8) has worst capacity. Moreover, each an increased as increases.
Positron Emission Tomography (PET) using time-of-flight information, which can greatly improve the quality of reconstructed image, has recently become an exciting topic.
