New building system aims to make Kiwi homes safe as houses in a quake – India Education | Latest Education News | Global Educational News

Ottawa invests over $2M to support fashion and clothing SMEs A prototype base isolation system for residential houses has been developed by Professor of Structural Engineering Tim Sullivan and his team and is currently being put through its paces on a ‘shake table’ in UC’s Structural Engineering Laboratory. A room has been specially built for the trial with timber framing and Gib-lined walls on a concrete slab foundation. The structure is positioned on top of the newly developed, steel base isolation units. Underneath this, a shake table – one of the largest in New Zealand – is being used to recreate ground movements recorded at various locations during the damaging Canterbury earthquakes, as well as other strong historical earthquakes and a simulated Alpine Fault quake.

华中科技大学学者制造出一种分级结构的超材料织物,穿上它可降温近5 ℃

7 月 11 日,记者从华中科技大学获悉,该校陶光明团队与多个科研单位交叉学科创新,突破性地研发了一种具有形态分级结构、可大批量制备的光学超材料织物(简称超材料织物),相较于白色棉织物,该织物对人体体表降温近 5 ℃,具有优异的可穿戴性,并与整个纺织行业相兼容,适合大规模推广制备和产业化应用。 访问: 超材料织物示意图 基于辐射制冷的原理和形态分级的设计理念,团队提出了一种形态分级结构的超材料织物,根据织物空间结构、纤维结构、以及纤维内部纳米结构,在不同空间、不同尺度上进行分级,形成了一种宏观有序、微观随机的形态学分级体系。根据该结构设计,将从太阳辐射波段到中红外波段 (0.3-25 μ m) 的光谱分为三段,交由超材料织物中的不同级次响应,最终实现紫外、可见-近红外及中红外波段的宽光
