二维材料是近年来材料科学和凝聚态物理学的前沿研究方向.在众多的二维材料中,黑磷(black phosphorus,BP)因其独特的带隙、优异的光学和电学性质、各向异性等特性而受到研究人员的广泛关注.如何可控制备二维薄层BP是该领域的难题之一.本工作系统研究了基底对BP生长的影响,结果表明金基底对BP的生长具有重要促进作用.在此基础上,使用镀有金薄膜的硅基底为生长衬底,通过设计限域生长空间和调控温度梯度,在全新的生长体系中实现了BP纳米片的直接生长,并探讨了其生长机理.本研究所报道的结果为实现二维薄层BP的制备提供了一条新思路.

对未来多年代际气候准确预测是气候变化研究的目标,也是当前气候领域的研究热点和极其困难的问题.截至目前,没有多年代际长期预测成功的实例报道,主要原因一是长期气候预测理论发展迟缓,二是足够长度的、精确的、高分辨率的、严格规范的气候代用指标十分缺乏.我们于2004年采用Caterpillar-SSA(毛毛虫-奇异谱分析法)方法对贺兰山地区树轮时间序列进行分解和趋势外推,预测了1998～2022年降水趋势.20多年后的今天,可以用气象观测数据对这个树轮预测结果进行客观评估,旨在探索更合适的年代际气候预测方法.评估
Thousands of resting state functional magnetic resonance imag-ing (RS-fMRI) articles have been published on brain disorders.For precise localization of abnormal brain activity,a voxel-level com-parison is needed.Because of the large number of voxels in th
To explore the rotational excitation of deformed halo nuclei,the angular momentum projection (AMP)has been implemented in the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc),in which both the mean field and collective wave functions a
The coronavirus epidemic may affect us far beyond the virus itself.Previously,there was a considerable body of evidence that maternal stress or other limitations caused by adverse events or emergencies,such as natural disasters,did indeed have long-term e
Ferroptosis is an iron-dependent form of cell death character-ized by an accumulation of lipid peroxides.A growing body of recent evidence supports the notion that ferroptosis plays an important role in mediating a wide variety of cellular processes in di
Diminishing petroleum reserves,together with emerging envi-ronmental concerns on the sustainability of the modern chemical industry,have triggered the research on diversifying raw materials,developing green processes,and producing value-added products.Thi
Arctic sea ice plays an essential role in regional and global cli-mate by dynamic processes and feedbacks associated with its high reflectivity,thermal insulation especially in presence of snow cover,and brine rejection [1].Both observations and model sim
Citation is the basis of many quantitative measures aimed at evaluating the achievements of different research bodies (e.g.,insti-tutions and scholars) [1].Many methods have been proposed recently for citation distribution analysis to find papers with mea
Recently,the hidden charm tetraquark states Zcs(3985) and Zcs(4000) with strangeness were observed by the BESⅢ and LHCb collaborations,respectively,which are great breakthroughs for exploring exotic quantum chromodynamics (QCD) structures.The first and fo
Metamaterials with higher-order topological band gaps that exhibit topological physics beyond the bulk-edge correspondence provide unique application values due to their ability of integrating topological boundary states at multiple dimensions in a single
