现今全球在能源生产和利用方面正面临着一个关于热能的突出悖论。全球总能源消耗中,有50%的能源用来产生热[1]。而在全球能源的转换利用过程中约有72%的能源主要以热能的形式耗散,造成能源利用效率低下以及废热耗散问题[2]。本文着手于解决余热收集再利用,提高能源利用率等问题,基于硫氰酸铵(NH4SCN)的逆庞压卡效应,首次提出"压卡热电池"(barocaloric thermal batteries)概念,即通过加压吸热,热量运输转移以及卸压放热三个过程实现热能在时间和空间上的转移利用。NH4SCN随着温度上升在364 K存在一个有序-无序的结构相变,相变熵变为128.7 J kg K。此相变过程为负热膨胀,且极易由压力驱动,在压力为20 MPa时可实现115 J kg K的等温熵变,并在压力为80 MPa时达到饱和。为表征"压卡热电池"实际应用性能,对NH4SCN卸载300MPa的压力,实现最大绝热温变为12 K的温升数值。经中子衍射,准弹性中子散射以及分子动力学模拟结果显示NHSCN相变熵变的主要来源:低温相的氢键在相变后被削弱,导致NH从氢键束缚的有序态转变成转动无序态,并造成5%左右的晶格体积变化。

At the China Spallation Neutron Source(CSNS), we have developed a custom gas-filling station, a glassblowing workshop, and a spin-exchange optical pumping(SEOP) system for producing high-quality ^(3)He-based neutron spin filter(NSF) cells. The gas-filling station is capable of routinely filling ^(3)He cells made from GE180 glass of various dimensions, to be used as neutron polarizers and analyzers on beamlines at the CSNS. Performance tests on cells fabricated at our gas-filling station are conducted via neutron transmission and nuclear-magneticresonance measurements, revealing nominal filling pressures, and a saturated ~3He polarization in the region of 80%, with a lifetime of approximately 240 hours. These results demonstrate our ability to produce competitive NSF cells to meet the ever-increasing research needs of the polarized neutron research community.
