Silicon(Si)is widely considered to be the most attractive candidate anode material for use in next-generation high-energy-density lithium(Li)-ion batteries(LIBs)because it has a high theoretical gravimetric Li storage capacity,relatively low lithiation vo
Flexible energy devices are the building blocks for next-generation wearable electronics.Flexible energy devices are expected to have multiple functions,such as energy conversion from light to electricity and vice versa,energy generation from triboelectri
【摘 要】《幼儿园教育指导纲要》明确指出:“幼儿的空间、设施、活动材料和常规要求等应有利于引发、支持幼儿的游戏和各种探索活动,有利于引发、支持幼儿与周围环境之间积极的相互作用。” 我们的幼儿园地处农村,有着丰富的自然资源,是全国有名的花木之镇,我们最优越的环境就是花草树木、大自然,因此,因地制宜,发挥农村特色,充分利用农村自然环境资源,将幼儿关注的、感兴趣的身边素材运用到幼儿园的活动中,提高幼儿的

Polymer semiconductors have aroused interests from both academic and industry due to their wide applications in electronic devices,such as organic thin-film transistors(OT-FTs)[1],polymer solar cells(PSCs)[2−6],organic thermoelectrics(OTEs)[7−11],and pero
p-Benzoquinone(BQ)is a promising candidate for next-generation sodium-ion batteries(SIBs)because of its high theoretical specific capacity,good reaction reversibility,and high resource availability.However,practical application of BQ faces many challenges
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
