An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale transistors.
Physicists have found a way to better understand the properties of manmade 'smart' materials. Their method reveals how stacked layers in such a material work together to bring the material to a higher level.
Silicon nanocones generate 200 times as much infrared luminescence as comparably sized nanocolumns when excited by visible light. Modelling and experimental results show that due to their geometry, cones are able to sustain what is referred to as whispering gallery modes at infrared wavelengths which can intensify the silicon luminescence. New applications are conceivable, including silicon-based nanolasers.
Scientists have discovered how to hide the reflective upper contact and funnel light directly to the semiconductor below. Their findings could lead to a new paradigm in the design and fabrication of solar cells.
A latticework of tiny tubes called microtubules gives your cells their shape and also acts like a railroad track that essential proteins travel on. But if there is a glitch in the connection between train and track, diseases can occur. Researchers reveal for the first time - atom by atom - the structure of one of these proteins bound to a microtubule.
Iron oxides occur in nature in many forms, often significantly different from each other in terms of structure and physical properties. However, a new variety of iron oxide surprised both physicists and engineers, as it revealed features previously unobserved in any other material.
Researchers have developed a first-of-its-kind self-healing gel that repairs and connects electronic circuits, creating opportunities to advance the development of flexible electronics, biosensors and batteries as energy storage devices.
Researchers successfully applied a new qualitative and quantitative method for the detection of a DNA sequence characteristic of Leishmania infantum kinetoplast, a frequent parasite in veterinary that affects humans too.
Researchers have examined the effect of ultrafast laser pulses on a low temperature superconducting material. Studying the way that light interacts with the superconductor at room temperature - and the effects of laser pulses on the material - gives insight into the change between metals and insulators.
In an important step toward creating a practical underwater glue, researchers have designed a synthetic material that combines the key functionalities of interfacial mussel foot proteins, creating a single, low-molecular-weight, one-component adhesive.
