超高压下的极端含能材料 Perspective

含有极高能量密度的单键聚合氮和单原子金属氢,常被称为极端含能材料。虽然它们需要几百吉帕的超高压才能合成,并且难以直接应用,但是研究它们的稳定性、亚稳定性和其他基本特性,仍然对另辟蹊径寻找极端含能材料甚有价值。在100~200 GPa,已经发现了多种结晶态和非晶态的聚合氮。立方偏转结构聚合氮和黑磷结构聚合氮是两种特别有意思的聚合氮,它们的滞后保存现象提供了进一步探索氮应用的前景。另外,虽然金属氢被预估具有最高的能量密度,但预测只能保存皮秒(ps)的寿命和只能合成皮克(pg)的质量,还不是一个有实用可能性的材料。因此金属氢应被定位为一个兴趣导向的基础科研课题,主要聚焦压力下分子氢的晶体构造和电子结构的奇妙演化过程,即从低密度超宽能带的绝缘体,到窄能带的半导体,再到高密度的分子金属和原子金属,最后到前所未有的崭新物理态。这些挑战驱动着超高压科学和技术的持续创新和突破。

NEW ZEALAND DAIRY FARM SYSTEMS AND KEY ENVIRONMENTAL EFFECTS
《农业科学与工程前沿(英文)》 2021年 第8卷 第1期
• NZ dairy farming systems are based on year-round grazing of perennial pasture (ryegrass/white clover).
• Milk production per hectare has increased by about 29% with increased use of externally-sourced feeds over the last two decades.
• Externally-sourced feeds with a low protein concentration can potentially reduce N2O emissions and N leaching per unit of production.
• Systems analysis is important for evaluating mitigations to minimize trade-offs between environmental impacts.
This paper provides an overview of the range of dairy pasture grazing systems used in New Zealand (NZ), the changes with increased inputs over time and associated key environmental effects including nitrogen (N) leaching and greenhouse gas (GHG) emissions. NZ dairy farming systems are based on year-round grazing and seasonal milk production on perennial ryegrass/clover pasture where cows are rotationally grazed in paddocks. There was an increase in stocking rate on NZ dairy farms from 2.62 cows ha−1 in 2000/2001 to 2.84 cows ha−1 in 2015/2016. During the same period annual milk solids production increased from 315 to 378 kg·yr−1 per cow. This performance has coincided with an increase in N fertilizer use (by ~ 30%) and a twofold increase in externally-sourced feeds. Externally-sourced feeds with a low protein concentration (e.g., maize silage) can increase the efficiency of N utilization and potentially reduce N losses per unit of production. Off-paddock facilities (such as standoff or feed pads) are often used to restrict grazing during very wet winter conditions. A systems analysis of contrasting dairy farms in Waikato (largest NZ dairying region) indicates that the increased input would result in an increase in per-cow milk production but little change in efficiency of milk production from a total land use perspective. This analysis also shows that the increased inputs caused an 11% decrease in N footprint (i.e., N emissions per unit of milk production) and a 2% increase in C footprint (i.e., greenhouse gas (GHG) emissions per unit of milk production).jiafa.luo@agresearch.co.nz
