Design and engineering of highly efficient emitting materials with assembly-induced luminescence,such as room-temperature phosphorescence (RTP) and aggregation-induced emission (AIE),have stimulated extensive efforts.Here,we propose a new strategy to obta
Synthesis of atomically dispersed catalysts with high metal loading and thermal stability is challenging but particularly valuable for industrial application in heterogeneous catalysis.Here,we report a facile synthesis of a thermally stable atomically dis
随着时代的进步,劳动及劳动教育实践的内涵不断拓展,不只局限于狭隘的体力劳动,新时代为劳动教育赋予了更多内涵.在学生成长过程中,教育应根据劳动形态的演化而与时俱进,在日常生活学习中,创设多样化情境让学生参加形式丰富的劳动实践,逐步树立生活与劳动相互孕育的理念及正确的劳动价值观,引导学生养成热爱劳动、热爱生活的习惯.文章通过举例论证了如何在生物教学中渗透劳动教育,帮助学生树立正确的劳动价值观,增强学生的科学劳动意识.
A set of red-light-excited,metal-free room-temperature phosphorescence(RTP)systems was constructed with brominated phenolsulfonephthaleine derivatives.The best metal-free RTP system has the reddest near-infrared(NIR)RTP emission(λp=819 nm)with the highest
为探索我国装配式建筑发展的制约因素,结合问卷调查,并借助结构方程模型搭建了我国装配式建筑产业制约因素的模型,分析了各因素之间的相互关系和作用原理.研究显示,市场因素对装配式建筑发展水平的影响最大,其他依次是认知因素、资金因素、政策因素和技术因素.最后,根据实证分析结果,提出了推进装配式建筑发展的相关对策建议.
The trade-off between efficiency and stability is a bit vague,and it can be tricky to precisely control the bulk morphology to simultaneously improve device efficiency and stability.Herein,three fused-ring conducted polymer acceptors containing furan,thio

The giant panda(Ailuropoda melanoleuca)is an iconic bear native to China,famous for eating almost exclusively bamboo.This unusual dietary behavior for a carnivore is enabled by several key adaptations including low physical activity,reduced organ sizes an
The glass transition is the most striking dynamic feature of glass-forming liquids and rigid glass,manifest in the follow-ing two scenarios [1].First,a viscous glass-forming liquid is transformed into a rigid glass state during cooling if the cooling rate
班会课是学生自我教育的平台,是师生情感沟通的桥梁,也是建立良好班风、进行品德教育的主阵地.传统班会费时费力,已不能满足当前班级管理的需求.随着经济、科技、信息技术的发展,教育理念的不断更新,受“微时代”的影响,“微班会”应运而生,及时、针对性地解决了班级管理中的一些问题,成为班级管理的新路径.文章在概述“微班会”概念及特点的基础上,结合当前小学班级管理中开展“微班会”的主要原则,浅谈利用“微班会”提升班级德育实效的策略.
