Memristive devices can mimic brain's capability to change synaptic connectivity

Scientists have demonstrated that memristive devices are excellent candidates to emulate synaptic plasticity, the capability of synapses to enhance or diminish their connectivity between neurons.

Blood-brain barrier on a chip sheds new light on 'silent killer'

An interdisciplinary team of researchers report that they have developed a microfluidic device that overcomes the limitations of previous models of this key system and have used it to study brain inflammation, dubbed the 'silent killer' because it doesn't cause pain but contributes to neurodegenerative conditions such as Alzheimer's and Parkinson's diseases.

New material could lead to erasable and rewriteable optical chips

Engineers have developed a nanomaterial that could lead to optical chips and circuits. The researchers believe they are the first to rewrite a waveguide, which is a crucial photonic component and a building block for integrated circuits, using an all-optical technique.

Improving the resolution of flow lithography produced nanostructures

The technique uses a Digital Light Processing (DLP) projector, similar to those used in projection TVs, to generate lithographic patterns. By overlapping low-resolution frames of the DLP projector a much higher-resolution frame can be produced.

Anomalously large charge transfer in an atomic layer cake of transition metal oxides

This work shows a path toward the development of electronics devices that are substantially more versatile and multifunctional than traditional semiconductors using various materials that could easily transition between a variety of electronic, magnetic, and spin states to achieve a wide range of functionalities in a single device.

Biodegradable polymers made by chemical vapor deposition

Biomolecules or drugs can be attached by means of special side groups. This introduces new possibilities for applications like the coating of biodegradable implants.

New method allows to study individual defects in transistors

All computer chips, which are each made up of huge numbers of transistors, contain millions of minor flaws. Researchers now have developed a method for studying individual defects in transistors.

Contact lens technology leads to supercapacity breakthrough

Major scientific breakthrough research has discovered new materials offering an alternative to battery power and proven to be between 1,000-10,000 times more powerful than the existing battery alternative - a supercapacitor.
