木质素是地球上最丰富的可再生酚类生物聚合物,很可能取代石油基芳烃聚合物。木质素的稳定可以实现经济可持续发展。木质素纳米颗粒(LNPs)是一种自组装的木质素胶体,具有生物可降解性和生物相容性的优点,近年来...
阅读全文3D打印技术又被称为增材制造,3D打印技术和刺激响应材料的结合又被称为4D打印技术。不同于3D打印的静态结构,4D打印技术制备的材料是一种可以在外界刺激下随时间变形的结构。在刺激响应材料中,形状记忆聚合物是...
阅读全文Schematic illustration of the design and mechanism of the IR780 loaded polymeric PD-1 blockade nanoparticles (aNP@IR780). (a) The nanoparticles were prepared by self-assembly of PEG-PLGA in the presen...
阅读全文进入5G时代与物联网社会,可穿戴电子产品飞速发展。然而,轻便耐用的可穿戴设备需要自身供电能力的支持。在此背景下,UCLA陈俊教授、澳大利亚伍伦贡大学李维杰研究员、北航宫勇吉教授合作对柔性锌离子电池体系进...
阅读全文全聚合物太阳电池(all-PSCs)是以聚合物给体和受体作为活性层的光电转换能源器件。相较于其他类型的有机太阳电池,all-PSCs在稳定性方面具有明显的优势,引起了业内的广泛关注。高性能聚合化小分子受体(PSMAs)...
阅读全文图1 基于喹啉螺旋的人工质子跨膜通道示意图 日前,杭州师范大学材料与化学化工学院刘俊秋教授团队在Nano Letters上发表题为“Unimolecular Helix-Based Transmembrane Nanochannel with a Smallest Luminal Cav...
阅读全文The new concept for seeing where the tweezers are reaching is to analyze the defocused laser-scattered light on a fast camera behind the object, which serves as a feedback signal. The more asymmetrica...
阅读全文"It is well known that the carrier density in graphene is highly sensitive to external perturbations. Such change in carrier density is reflected in the drain current. Although there was some attempt ...
阅读全文Professor Dr Dieter Willbold, Director of the HHU Institute of Physical Biology and the FZJ Institute for Structural Biochemistry, adds: “The study is yet another example of how basic research in str...
阅读全文Peter Bøggild emphasises that these three problems have not been solved with the new method alone: “We have taken a very significant step. We have converted a laminating machine into a so-called rol...
阅读全文Ge thin films can be grown using the solid-phase crystallization technique. These thin films are polycrystalline, meaning they are made up of many Ge crystals. In general, larger crystals lead to grea...
阅读全文The technique enables a strong modulation of the electron beam, with only a few milli-Watts from a continuous wave laser – a power level generated by a common laser pointer. The approach constitutes ...
阅读全文‘Ferrofluids have drawn the attention of scientists, engineers and artists since their discovery in 1960s. Now, we have found a truly facile approach to control their magnetic properties on-the-fly j...
阅读全文As proof of concept, the team integrated ultra-thin organic photovoltaic and LED-light modules that were printed on separate films and connected by five additional polymer films. The devices withstood...
阅读全文“The present discovery, although not practical for a mass-production of tiny transistors, shows a novel fabrication principle and opens up a new horizon of using thermomechanical treatments of nanotu...
