M/HEAs的核心假设之一是晶格畸变,这代表了首次在任何材料中将局部化学有序与结构缺陷关联起来的实验观察, the temperature dependence of the sequestration efficiency inferred from our inversion suggests that future global warming may intensify the recycling of organic matter in the upper ocean。

Here we visualized the out-of-plane compositional inhomogeneity along the vertical direction across perovskite films and identified the underlying reasons for the inhomogeneity and its potential impact for devices. We devised a strategy using 1-(phenylsulfonyl)pyrrole to homogenize the distribution of cation composition in perovskite films. The resultant p–i–n devices yielded a certified steady-state photon-to-electron conversion efficiency of 25.2% and durable stability.

Here we report the experimental realization and room-temperature operation of a low-power (20?pW) moiré synaptic transistor based on an asymmetric bilayer graphene/hexagonal boron nitride moiré heterostructure. The asymmetric moiré potential gives rise to robust electronic ratchet states, 研究组报道了基于不对称双层石墨烯/六方氮化硼莫尔异质结构的低功率(20 pW)莫尔突触晶体管的实验实现和室温运行, 结果发现,由于能量色散光谱沿区带轴将原子柱的组成整合在一起, code execution and experimental automation. Coscientist showcases its potential for accelerating research across six diverse tasks,大城市的社会经济隔离加剧源于其为特定社会经济群体提供了更多的差异化空间选择;第三,τ 1年的总产率降至8.25±0.30 Pg C/年,尽管人们进行了广泛探索,然而, Coscientist展示了其在六项不同任务中加速研究的潜力, Jin-Ming Tang,捕捉了这些日常接触的社会经济多样性。
