　　【化工仪器网科技前沿】近几十年来，科技的飞速发展为我们的生活带来了巨大改变，而曾经的科学幻想也在不断成熟的技术帮助下，逐渐成为了现实。但与此同时，社会的发展也让一些原本不明显或者没有的问题出现在了我们的面前，如何解决这些问题，似乎成为了科研寻求发展的方向。而在这之中，材料学的发展，无疑是为科研发展提供了一个重要基础。

　　让光热转化更高效一种来自于玫瑰、玉米秸秆的新材料

　　太阳能作为一种绿色清洁的能源，不但可以用于发电，同时还能用于生产“绿氢”这种颇受关注的新型燃料。也正因为如此，太阳能被认为是有利于解决淡水资源缺乏和能源危机等迫切问题的关键之一。

　　而提到太阳能的运用，光热转化材料始终是一个不能避免的话题，而就在前些时间，《纳米能源》期刊发表了一项关于新型复合材料的研究报告，而这种材料便有着优异的吸收性和更高光热转换效率，一定程度上能满足太阳能运用的发展需求。

　　据悉，该材料由云南大学材料与能源学院副教授万艳芬、杨鹏团队(以下简称：团队)研制而成，其不俗的性能是材料的组分和结构共同作用的结果。对于光热材料来说，成分是影响其热转化效率的重要因素，而团队通过对等离子体贵金属、半导体和碳基材料进行复合研究，发现了一套特殊的成分方案，通过将金纳米锥和碳点加入到材料中，使材料的金-钼酸铋-碳点形成一种特殊的平衡关系，避免了电子在材料上移动时可能存在的损耗，从而增强了材料的光热性能。

　　而在结构上，团队则是参考了玫瑰、玉米秸秆等自然界中一些组织结构特别的植物，并通过碳化前后这些植物三维扫描图像的变化寻找到了一种能对光产生更好吸收的结构方案，并将这种特殊的结构融入到材料中提升其光热的转化效率。

　　目前，这种材料正在不断的完善并尝试应用，并且，团队还发现这种材料在智能穿戴等领域也有很好的前景，或许在不远的将来能为我们生活的改变提供重要的助力。

　　特殊铺面材料让城市地面会呼吸

　　交通是一个城市的经济命脉，它承载着居民的出行、货物的运输等多个环节，而与交通直接挂钩的要素便是路面。如今城市路面在牢固性和耐用性上都有了明显的突破，但是硬质铺面不透水的问题却依旧影响着道路的使用寿命。

　　一方面，不透水的铺面破坏了天然土壤对于降水入渗、储蓄和净化功能；另一方面，路面积水不但会影响路面寿命，还会引起城市内涝、加重城市热岛效应、造成环境污染。而就在前些日子，扬州大学建筑科学与工程学院康爱红教授团联合多家公司研发除了多种渗蓄净水型铺面新材料，这种材料能够一定程度上起到“渗水蓄水”“净水洁水”“降洪防涝”的功能。而目前，这种材料正在进行试用与推广。

　　事实上，材料学的发展有时候看起来似乎和我们的生活遥不可及，但更多时候是从我们的生活需求出发，用新材料、新技术来解决我们生活上的问题，在潜移默化中，为我们的生活带去改变。
