We report results on the searches of weakly interacting massive particles (WIMPs) with sub-GeV masses (m_{χ}) via WIMP-nucleus spin-independent scattering Migdal effect incorporated. Analysis time-integrated (TI) and annual modulation (AM) effects CDEX-1B data are performed, 737.1 kg day exposure 160 eVee threshold for TI analysis, 1107.5 250 AM analysis. The sensitive windows in m_{χ} expanded by an order magnitude to lower DM New limits σ_{χN}^{SI} at 90% confidence level derived as...
We report the first results of a light weakly interacting massive particles (WIMPs) search from CDEX-10 experiment with 10 kg germanium detector array immersed in liquid nitrogen at China Jinping Underground Laboratory physics data size 102.8 day. At an analysis threshold 160 eVee, improved limits 8×10^{-42} and 3×10^{-36} cm^{2} 90% confidence level on spin-independent spin-dependent WIMP-nucleon cross sections, respectively, WIMP mass (m_{χ}) 5 GeV/c^{2} are achieved. The lower reach m_{χ}...
We present new constraints on light dark matter boosted by cosmic rays (CRDM) using the 205.4 kg day data of CDEX-10 experiment conducted at China Jinping Underground Laboratory. The Monte Carlo simulation package CJPL\_ESS was employed to evaluate Earth shielding effect. Several key factors have been introduced and discussed in our CRDM analysis, including contributions from heavier CR nuclei than proton helium, inhomogeneity distribution, impact form factor attenuation calculation. Our...
Low hardness and poor wear resistance are major limitations of Al alloys, which hinder their application in several fields, especially automotive moving parts. DLC can effectively improve but high residual stress adhesion limit the film thickness. Multilayer thick films (~10 μm) composed alternating Ti Ti-DLC layers were successfully deposited on alloys. The influence content microstructure, mechanical tribological properties was emphasized. As decreased from 10.42 to 1.35 at.%,...
Graphene oxide–titanium (GO-Ti) composite materials were fabricated using GO as a precursor and then anchoring nano titanium (Nano-Ti) particles on sheets with the help of silane coupling agent. Then, coating samples prepared by dispersing GO, Nano-Ti particles, GO-Ti in an epoxy resin at low weight fraction 1 wt %. The composites investigated X-ray photoelectron spectroscopy (XPS), diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), transmission (TEM)....
We demonstrated that in vivo brain glioma a mouse model using continuous-wave terahertz reflection imaging system, as well the ex fresh tissues model. The tumor regions of and can be distinguished by THz intensity at frequency 2.52THz. images with high sensitivity correlated magnetic resonance, visual hematoxylin eosin stained images. Furthermore, spectral difference between gliomas normal were obtained 0.6THz to 2.8THz range, where have higher refractive indices absorption coefficients,...
Dark matter direct detection experiments mostly operate at deep underground laboratories. It is necessary to consider shielding effect of the Earth, especially for dark particles interacting with a large cross section. We analyzed and simulated Earth China Jinping Underground Laboratory (CJPL) simulation package, CJPL Shielding Simulation code (CJPL_ESS), which applicable other locations. The further constraints on $\ensuremath{\chi}\text{\ensuremath{-}}\mathrm{N}$ section exclusion regions...
We present improved germanium-based constraints on sub-GeV dark matter via matter-electron (χ-e) scattering using the 205.4 kg·day dataset from CDEX-10 experiment. Using a novel calculation technique, we attain predicted χ-e spectra observable in high-purity germanium detectors. In heavy mediator scenario, our results achieve 3 orders of magnitude improvement for m_{χ} larger than 80 MeV/c^{2} compared to previous results. also most stringent cross-section limit date among experiments...
Multilayers of Ti doped diamond-like carbon (Ti-DLC) coatings were deposited on aluminum alloys by filtered cathodic vacuum arc (FCVA) technology using C₂H₂ as a reactive gas.
