The preparation of self-supporting anion exchange membranes with enhanced mechanical strength and ultrathin thickness is still a challenge to improve the performance fuel cells.
Oedaleus decorus asiaticus (O. decorus) is a significant pest in the grasslands of Inner Mongolia, posing considerable challenges to development animal husbandry. To understand key factors influencing population distribution O. decorus, field surveys were conducted from 2018 2020, during which count, growth stage, and location information recorded. Daily soil moisture (SM) data daily land surface temperature (LST) obtained National Tibetan Plateau Data Center, Generalized Additive Model...
We report a novel high speed directly modulated dual wavelength 1.3 μm laser for THz communication applications. The has compact size and simple structure, which consists DFB section passive distributed Bragg reflector (DBR) section, leading to device fabrication procedure similar that of normal laser. an over 26 GHz modulation bandwidth in the working mode, facilitates data onto wave. NRZ modulations at up 50 Gb/s have been demonstrated successfully. bit error rate (BER) performances under...
Polarimetry plays an important role in the measurement of solar magnetic fields. We developed a high-sensitivity and high-accuracy polarimeter (HHP) based on nematic liquid crystal variable retarders (LCVRs), which has compact setup no mechanical moving parts. The system design calibration methods are discussed detail. azimuth error transmission axis polarizer as well fast axes two LCVRs quarter-wave plate were determined using dedicated procedures. Linearly circularly polarized light...
1.5 µm wavelength high power buried heterojunction (BH) semiconductor lasers having dilute waveguide structure have been fabricated. The optical field is dragged down toward the n side of device by layer, lowering confinement factor p doped material and active material, which helps to enlarge laser output light power. Compared with thick InGaAsP cladding easy be grown has higher thermal conductivity. slope efficiency obtained BH notably than that no waveguide. Our studies show promising for...
Oedaleus decorus asiaticus is one of the dominant harmful pests in central Inner Mongolia, China. Large-scale outbreaks this pest create many serious problems animal husbandry and agriculture. Therefore, understanding underlying mechanisms between plant losses Odecorus at different density levels growth stages can guide development monitoring prediction measures to reduce damage. In study, an unmanned aerial vehicle (UAV) carrying a camera was employed collect multi-spectral data. Further,...
The light reflected from planets is polarized mainly due to Rayleigh scattering, but starlight normally unpolarized. Thus it provides an approach enhance the imaging contrast by inducing polarimetry technique. In this paper, we propose a high-contrast polarimeter that optimized for direct of exoplanets, combined with our recently developed stepped-transmission filter based coronagraph. Here present design and calibration method system associated test its performance. system, two liquid...
HIAF (High Intensity heavy ion Accelerator Facility) is a new accelerator complex under construction at the Institute of Modern Physics. As main injector this project, high-charge-state ECR source needs to provide intense uranium beams, such as 700 eμA U35+. This requires performance metal ovens be further improved so that crucible can operate an ultrahigh temperature for long time without damage in high magnetic field (>3 T). In order meet these requirements, inductive oven with...
Abstract The portable adaptive optics (PAO) device is a low-cost and compact system, designed for 4- meter class telescopes that have no (AO) because of the physical space limitation at Nasmyth or Cassegrain focus historically high cost conventional AO. initial scientific observations PAO are focused on direct imaging exoplanets sub-stellar companions. This paper discusses concept associated high-contrast performance in our recent observational runs. deliver Strehl ratio better than 60% H...

Abstract Polarimeters play a key role in investigating solar magnetic fields. In this paper, High speed and high efficiency Imaging POlarimeter (HIPO) is proposed based on pair of ferroelectric liquid crystal retarders (FLCs), with the ultimate goal measuring fields prominences filaments from ground. A unique feature HIPO that it enables cadence polarization measurements covering wide field view (FOV); modulation frequency able to achieve ∼100 Hz, which greatly suppresses seeing-induced...
