Thin-film transistors get wavy

flexible_electronicsFor enhanced visualization experience, high resolution display technology with fast frame rate to suppress the motion blur at that resolution is essential. In modern display technologies, which are mostly active matrix display system, there are planar thin film transistors (TFTs) which enable both high resolution and fast imaging. Scaled TFTs can provide high resolution. Fast switching can be facilitated by the scaling as well as high mobility channel material. In new work, researchers have shown that both high resolution and fast frame rate display technology is possible, irrespective of the active channel material.

Atomic tuning of electrocatalysts

Efficient electrocatalysts lie at the heart of a series of significant energy conversion and storage technologies, and atomically precise understanding of the influences of component dopants is crucial for looking into the reaction mechanism and controlled synthesis of the desired electrocatalysts. Graphitic carbon nitride is a promising electrocatalytic material owing to its intrinsically high N content and abundant edge sites. This material has been researched towards some of the most significant electrocatalytic reactions including oxygen reduction/evolution reaction and hydro evolution reaction. New work has comprehensively explored the influences of component elements within graphitic carbon nitride motiety for electrocatalytic reactions.

Nanotechnology materials inspired by nature

The remarkable properties of some natural materials have motivated many researchers to synthesize biomimetic nanocomposites and other nanostructured materials that attempt to reproduce Nature's achievements. Recent research has indicated that the amplification of natural materials' mechanical properties far beyond those of the components that comprise them originates mainly from: 1) a hierarchical micro-/nanoscale architecture and 2) abundant effective interface interactions. A new progress report provides insight into the development of bio-inspired structural materials.

CNT/MOF nanocomposites enhance the performance of humidity sensors

nanocompositeMetal-organic frameworks (MOFs) are well-ordered, lattice-like crystals. The nodes of the lattices are metals, which are connected by organic molecules. Their size-controllable nanopores, special structure and large surface area make MOFs very attractive materials for next-generation, highly sensitive gas sensors. In new work, researchers demonstrate a process that can be used for developing low-cost and highly sensitive gas sensors. By increasing the sensitivity, the amount of gas sensitive material and device size can be reduced which in turn would reduce the overall cost of the device and energy consumption.

Virtual cell model predicts cell response to substrate topography (w/video)

virtual_cell_modelThe crucial roles of the physicochemical properties of cell culture substrates on function and behavior of a wide range of the cells are becoming well-studied in the current literature, using experimental approaches. However, development of in silico approaches for prediction of cell responses to the physicochemical properties of substrates is still in its infancy. In new work, an international team of researchers has developed a unifying computational framework to create a multi-component virtual cell model to probe cell function/behavior in silico.

Reversibly controlling the learning properties of memristors via optical means

memristorMemristors present an opportunity to make new types of computers that are different from existing von Neumann architectures, which traditional computers are based upon. In new work, researchers have demonstrated the ability to reversibly control the learning properties of memristors via optical means. They show that light can be used in a reversible manner to change the connection strength (or conductivity) of artificial memristor synapses and as well control their ability to forget i.e. we can dynamically change device to have short-term or long-term memory. The reversibility is achieved by changing the polarization of light.

Ultra-thin graphene-based encapsulation for OLEDs

OLEDResearchers have reported on improved performance of graphene-based moisture barrier layers. By combining catalytic CVD and ALD they created in scalable fashion nanolaminates of few-layer graphene and aluminium oxid. Unlike previous reports, this new approach exploits the synergy between different materials and growth techniques. These nanolaminates also are a potential material to be included in standard multi-stacked barrier layers to enhance the performance of existing ALD aluminium oxide and produce next generation moisture barriers.
