无金属卤化物钙钛矿(MFHaP)因其出色的光电性质、化学兼容性、轻量级特征和环保性能,受到了广泛关注.传统的MFHaPs材料主要是在A位采用DABCO^(2)+(1,4-二氮杂二环[2.2.2]辛烷)及其衍生物和B位采用铵根离子组成的,这种结构一般都有较低的硬度和高的离子迁移.为了克服这些难题,我们通过在A位引入了笼状有机阳离子六亚甲基四胺(hmta^(2+)),成功合成了具有较高机械硬度(1.5 GPa)的hmtaNH_(4)Br_(3)单晶.这主要得益于hmta-NH_(4)Br_(3)单晶中较短的氢键和更接近1的容忍因子.此外,hmta-NH_(4)Br_(3)单晶还表现出优异的结构稳定性和环境稳定性.采用低缺陷hmta-NH_(4)Br_(3)单晶构建的X射线探测器不仅大幅减少了离子迁移,还实现了150μC Gyair^(-1)cm^(-2)的高灵敏度,展现了其在高能辐射检测领域的巨大潜力.

Composting as a solution to the increasing generation of municipal solid waste (MSW), also contribute to GHGs emission when not controlled and could lack some basic nutrients, especially nitrogen. This study assessed the split-additions of nitrogen-rich substrate to composting materials and their effect on GHGs emissions as well as the quality of the composts. Nitrogen-rich substrates formulated from pig and goat manure were co-composted with MSW for a 12-weeks period by split adding at mesophilic (˚C) and thermophilic (>50˚C) stages in five different treatments. Representative samples from the compost were taken from each treatment for physicochemical, heavy metals and bacteriological analysis. In-situ CH4, CO2, N2O gas emissions were also analyzed weekly during composting. It was observed that all the treatments showed significant organic matter decomposition, reaching thermophilic temperatures in the first week of composting. The absence affects the suitable agronomic properties. All nitrogen-rich substrate applied at thermophilic stage (Treatment two) recorded the highest N, P and K concentrations of 1.34%, 0.97% and 2.45%, respectively with highest nitrogen retention. In terms of GHG emissions, CO2 was highest at the thermophilic stage when N-rich substrate was added in all treatment, while CH4 was highest in the mesophilic stage with N-rich substrate addition. N2O showed no specific trend in the treatments. Split addition of the N-rich substrate for co-composting of MSW produced compost which is stable, has less nutrient loss and low GHG emissions. Split addition of a nitrogen-rich substrate could be an option for increasing the fertilizer value of MSW compost.
