Anion-immobilized solid composite electrolytes(SCEs)are important to restrain the propagation of lithium dendrites for all solid-state lithium metal batteries(ASSLMBs).Herein,a novel SCEs based on metal-organic frameworks(MOFs,UiO-66-NH2)and su
Wide-bandgap copolymer donors with fused-ring accept-or units(FAUs)present excellent performance in non-fullerene organic solar cells due to their complementary light-absorption with nonfullerene acceptors,deep the highest occupied molecular orbital(HOMO)
White light emitting diodes from a single emitter is of sig-nificance in application of illumination and image display be-cause of avoiding the color instability in devices with mul-tiple emitters[1,2].Recently,as a single emitter,low-dimension-al halide
As containing earth-abundant elements,kesterite(Cu2Zn-Sn(S,Se)4,CZTSSe)semiconductors have great potential to be low-cost and environmental-friendly inorganic absorbers.However,the record power conversion efficiency(PCE)for CZTSSe so
Since Geim et al.firstly separated graphene from graph-ite by mechanical exfoliation method in 2004,the research of two-dimensional(2D)van der Waals(vdW)layered materials has begun[1].Compared with three-dimensional materials,2D vdW layered materials expo
Donor-acceptor(D-A)conjugated copolymers contain-ing fused-ring acceptor units demonstrate outstanding per-formance in organic solar cells(OSCs)[1−13].We have in-vented highly efficient D-A copolymer donors D18 and D18-Cl by using a fused-ring acceptor un
Flexible batteries are key component of wearable electronic devices.Based on the requirements of medical and primary safety of wearable energy storage devices,rechargeable aqueous zinc ion batteries(ZIBs)are promising portable candidates in virtue of its
【摘 要】游戏是幼儿最喜爱的活动，是幼儿自主性、创造性的成长的一种方式。游戏与发现问题、解决问题是自然地融为一体的，它为幼儿提供了自由探索大胆想象的机会，幼儿在实现游戏意图的过程中会不断碰到这样或那样的问题，他们需要面对不同的问题，进行思考，探索解决问题的各种方法，体会其中乐趣，使游戏得以继续下去，愿意得以最终实现。 【关键词】自我发展；动手能力；感情；智力；社会性；感受力 古往今来，无论哪个
【摘 要】在放宽生育，允许生育二胎的政策之下，许多家庭迎来自己的第二胎子女，由此也出现了许多问题。儿童因为对第二胎的到来不适应，同时家庭地位的变化和受到的教育比较少，导致第一胎子女心理产生了偏差，这种扭曲的心理作用有时还会促使这些儿童做出一些偏激的行为，对家庭关系和健康产生不良影响。这个现象应该引起重视，需要一步步走进儿童的心理，读懂这个形势之下孩子的内心需要。也需要适时地更新儿童教育，可以从家庭
【摘 要】随着当代社会高科技的不断发展，对新一代的综合素质要求越来越高，在全面实施素质教育的今天， 教育研究者和教育工作者越来越深刻地认识到教育不光是学校、老师的责任， 更是家庭和社会的共同责任。作为社会细胞的家庭， 是孩子身心和谐发展的最重要的场所， 家庭教育对孩子学习习惯的形成和发展的影响是长远而深刻的。 【关键词】家庭教育；学习习惯；培养 影响家庭教育是一个亘古常新的话题，而早期家庭教育
