Some researchers are driven by the quest to improve a specific product, like a battery or a semiconductor. Others are motivated by tackling questions faced by a given industry. Rob Macfarlane, MIT’s P...
Gel-like materials that can be injected into the body hold great potential to heal injured tissues or manufacture entirely new tissues. Many researchers are working to develop these hydrogels for biom...
Pushing a shovel through snow, planting an umbrella on the beach, wading through a ball pit, and driving over gravel all have one thing in common: They all are exercises in intrusion, with an intrudin...
As a river cuts through a landscape, it can operate like a conveyer belt, moving truckloads of sediment over time. Knowing how quickly or slowly this sediment flows can help engineers plan for the dow...
Researchers at MIT have developed a technique for precisely controlling the arrangement and placement of nanoparticles on a material, like the silicon used for computer chips, in a way that does not d...
What if emergency medical personnel could treat a desperately ill patient in need of oxygen with a simple injection instead of having to rely on mechanical ventilation or rush to get them onto a heart...
There are currently few good treatment options for glioblastoma, an aggressive type of brain cancer with a high fatality rate. One reason that the disease is so difficult to treat is that most chemoth...
Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors....
New research published in Nature Physics details the relationship between a disordered material’s individual particle arrangement and how it reacts to external stressors. The study also found that the...
Ligands are much like nanosized barnacles, binding to many kinds of surfaces. This form of adsorption is crucial for a range of chemical processes, from purification and catalysis to the design of nan...
虽然颗粒分拣对于医学研究,以及确定岩石、化石和沉积物的年代至关重要,但现有技术无法对直径超过100微米的颗粒进行大规模分拣。为了克服这一障碍,研究人员开发了一种利用微射流产生的移动旋涡的新分拣方法。而且,该技术是通过荧光检测激活的。作为4月16日出版的《科学进展》封面故事的论文提到,研究人员用该方法对160微米的颗粒进行了分类,并以2.9千赫兹的频率从湖泊沉积物中纯化出花粉化石,进而获得了样本的放...
To assess the role of particle roughness in the rheological phenomena of concentrated colloidal suspensions we develop model colloids with varying surface roughness length scales up to 10% of the part...
据芬兰国家技术研究中心(VTT)近期发布的消息,该中心已经成功开发了一种用于纳米颗粒批量生产的高效合成反应器,可以制备各种纯金属颗粒、各类合金颗粒和碳涂布颗粒,日产量可以达到数百克甚至几公斤。
2005年9月15日,英国利兹大学化工系颗粒研究所高级讲师丁玉龙博士来天津大学访问,作了题为“纳米流体的现状与工业应用的挑战”学术报告,并与师生进行了交流。
