Researchers have developed a human airway muscle-on-a-chip that could be used to test new drugs because it accurately mimics the way smooth muscle contracts in the human airway, under normal circumstances and when exposed to asthma triggers.
Scientists have developed a new technique that expands the benefit of super-resolution microscopy to study biological questions. This method contributes to understand on how cells renew, distribute and transport their molecular and subcellular components.
Engineers discovered a way to create a special material - a metal layer on top of a silicon semiconductor - that could lead to cost-effective, superfast computers that perform lightning-fast calculations but don't overheat.
Researchers have developed molybdenum di-sulphide (MoS2), a similar material to graphene that shares many of its properties, including extraordinary electronic conduction and mechanical strength, but made from a metal (in this case molybdenum combined with sulphur).
In experiments using graphene, researchers have been able to demonstrate a phenomenon predicted by a Russian physicist more than 50 years ago. They analysed a layer structure that experts believe may hold unimagined promise.
Researchers have discovered a way to create a highly sensitive chemical sensor based on the crystalline flaws in graphene sheets. The imperfections have unique electronic properties that the researchers were able to exploit to increase sensitivity to absorbed gas molecules by 300 times.
Scientists have determined that bulk coherent acoustic vibrations are heavily damped by scattering from radially aligned nanosized pores within hypersonic crystals of closely packed colloidal silica. Surface acoustic modes are much less influenced, suggesting new ways to manipulate thermal transport via phonon propagation control.
