The Gamma-ray Transient Monitor(GTM) is an all-sky monitor onboard the Distant Retrograde Orbit-A(DRO-A) satellite with the scientific objective of detecting gamma-ray transients ranging from 20 ke V to 1 MeV. The GTM was equipped with five Gamma-ray Transient Probe(GTP) detector modules utilizing a nai(Tl) scintillator coupled with a SiPM array. To reduce the SiPM noise, GTP uses a dedicated dual-channel coincident readout design. In this work, we first studied the impact of different coincidence times on the detection efficiency and ultimately selected a 0.5 μs time coincidence window for offline data processing. To test the performance of the GTPs and validate the Monte-Carlo-simulated energy response, we conducted comprehensive ground calibration tests using the Hard X-ray Calibration Facility(HXCF) and radioactive sources, including the energy response, detection efficiency, spatial response, bias-voltage response, and temperature dependence. We extensively present the ground calibration results and validate the design and mass model of the GTP detector, thus providing the foundation for in-flight observations and scientific data analysis.

Polysaccharide from traditional Chinese herb, Saposhnikovia divaricata(Turcz.) Schischk.(SD) was extracted, fractionated and characterized in this work. Four fractions were prepared. Their molecular weight, monosaccharide compositions, linkage modes and structural properties were characterized with SEC-MALS-RI, HPAEC-PAD, GC-MS and NMR. SDP1 was assigned as a 1, 4-α-glucan with small amount of O-6 linked branches. SDP2 contained a big amount of the 1, 4-α-glucan and a small amount of arabinogalactan, while SDP3 possessed relatively lower amount of the 1, 4-α-glucan and a big amount of the arabinogalactan. SDP4 was defined as a pectic arabinogalactan. Four fractions showed antioxidant activities in both molecular and cellular levels and their activity was ranked as SDP4 ≈ SDP3>SDP2>SDP1. The 1, 4-α-glucan in SDP1 had the weakest, while SDP3 and SDP4 showed similar and the highest antioxidant activity. The arabinogalactan was the major component of both SDP3 and SDP4, which significantly contributed to the antioxidant activity of SDP.

2,3,7,8-四氯二苯并对二噁英(2,3,7,8-TCDD)是二噁英家族中危害人类和环境最显著的一种.设计一种高效,灵敏的吸附剂来检测和去除2,3,7,8-TCDD对人类和环境的影响是亟需解决的问题.本研究利用基于密度泛函理论(DFT)的计算模拟方法探索了本征磷烯对2,3,7,8-TCDD的吸附机理,并详细考察了掺杂Ti,Fe,Ca,Al金属原子后磷烯对2,3,7,8-TCDD吸附的影响.研究结果表明2,3,7,8-TCDD初始构型会影响磷烯对其吸附,当平躺于磷烯表面时有较大的吸附.而且掺杂金属原子的磷烯对2,3,7,8-TCDD的吸附也存在较大的影响,掺杂金属原子均增大了磷烯对2,3,7,8-TCDD的吸附,其中Ca掺杂磷烯>Fe掺杂磷烯>Ti掺杂磷烯>Al掺杂磷烯.研究结论对于2,3,7,8-TCDD的处理带来了新的思考方向,有望为二噁英的检测和去除提供有用的理论指导.

Stable thin films made from polyionic complex 2.12N+PVS- with incorporated Hb on PG electrodes were characterized by electrochemistry. The electron transfer between Hb and PG electrodes was greatly facilitated in microenvironment of 2.12N+PVS- films. The Hb-2.12N+PVS-films could be used to catalytically reduce trichloroacetic acid.
