目前,艾草制绒后的剩余物没有被深度利用而造成了中药材资源的浪费,而且艾草粉体学性质的研究鲜见文献报道,在一定程度上阻碍了艾草产业的可持续发展。为粉体的分级、分散、包装以及制粒等处理工艺及相关加工机械提供参考依据,有必要分析其粉体学特性。以石磨制取艾绒后的艾草剩余物为试验材料,通过剪切粉碎法制备多尺度粉体,采用BT-1000粉体综合特性测试仪测定休止角、崩溃角、松装密度、振实密度、分散度等粉体学参数,分析粒度和含水率对流动性、压缩性及喷流性的影响规律。试验分析表明:粒度和含水率对艾叶制绒后剩余物的粉体综合特性影响明显。随粒度增大,流动性呈现先降后升的趋势,而压缩性和喷流性则表现出先增后减的特征;随含水率增加,流动性和喷流性逐渐降低,而压缩性逐渐增大。根据休止角θr<45°、崩溃角θf<40°、差角θd<15°、压缩度Cp<20%、分散度Da<20%,再结合Carr流动性和喷流性指数评价表,分析认为粉体的流动性、压缩性和喷流性均较弱。以试验结论为参考,通过粒度或含水率控制某些粉体学特性,使其满足特定处理工艺要求,也可为粉体加工机械的结构优化提供设计依据,促进中药材加工剩余物的再利用。

Highly sensitive photodetectors operating at mid-infrared(MIR) wavelengths are urgently required for the applications of astronomy, optical communication, security monitoring, and so forth. However,further promoting the sensitivity in conventional MIR devices for a higher detectivity is challenging. Among the potential strategies, integrating localized surface plasmon resonance with MIR semiconductors is a promising approach to developing high-performance optoelectronics. Here we demonstrate a high-sensitivity boron(B)-doped silicon quantum dot(Si-QD)/HgCdTe(MCT) MIR photodetector. Because of plasmon-induced hot-hole tunneling and enhanced light absorption, the hybrid photodetector exhibits a high specific detectivity of ～1.6×109cm·Hz1/2·W-1(Jones) and a high-speed response(～224 ns for the rise time and ～580 ns for the fall time) at room temperature. Furthermore, the device achieves high-performance spectral blackbody detection with a peak detectivity of up to 1.6×1011Jones at ～5.8 μm under a cryogenic environment of 77 K, higher than that of bare MCT. This prominent enhancement can be attributed to the further suppression of hot-hole cooling due to a reduced phonon population at low temperatures, which facilitates more efficient hot-carrier extraction and contributes to ultrahigh sensitivity. The plasmonic material-integrated MCT architecture can pave the way for developing high-performance MIR photodetection.

Hexamethylenediamine(HMDA) is an important reagent for the synthesis of Nylon-6,6, and it is usually produced by the hydrogenation of adiponitrile using a toxic reagent of hydrocyanic acid. Herein, we developed an environmental friendly route to produce HMDA via catalytic reductive amination of 1,6-hexanediol(HDO) in the presence of hydrogen. The activities of several heterogeneous metal catalysts such as supported Ni, Co, Ru, Pt, Pd catalysts were screened for the present reaction in supercritical ammonia without any additives. Among the catalysts examined, Ru/Al_2O_3 presented a high catalytic activity and highest selectivity for the desired product of HMDA. The high performance of Ru/Al_2O_3 was discussed based on the Ru dispersion and the surface properties like the acid-basicity. In addition, the reaction parameters such as reaction temperature,time, H_2 and NH_3 pressure were examined, and the reaction processes were discussed in detail.
