Scientists have managed to build a fully functional neuron by using organic bioelectronics. This artificial neuron contain no 'living' parts, but is capable of mimicking the function of a human nerve cell and communicate in the same way as our own neurons do.
The patch - a thin square no bigger than a penny - is covered with more than one hundred tiny needles, each about the size of an eyelash. These microneedles are packed with microscopic storage units for insulin and glucose-sensing enzymes that rapidly release their cargo when blood sugar levels get too high.
A new technique which enables researchers to visualise the activity of individual ions inside battery-like devices called supercapacitors, could enable greater control over their properties and improve their performance in high-power applications.
Scientists have invented a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas 24 hours a day, seven days a week. The device could provide a renewable source of clean-burning hydrogen fuel for transportation and industry.
Using a simple structure comprising a mirror and an absorbing layer to take advantage of the wave properties of light, researchers have developed a display technology that harnesses natural ambient light to produce an unprecedented range of colors and superior viewing experience.
One completed a series of theoretical calculations to predict its properties with the help of a massive computing center. The other grew it in bulk before waxing its atom-thin whiskers with the assistance of adhesive tape.
In the future, a little bend in your smartphone might be considered a feature rather than a defect. An important component of future electronics that can be rolled up, folded or embedded in flexible objects is the stretchable conductor, which would make up components like wires and electrodes.
Scientists have unveiled a breakthrough approach in two publications for growing and integrating nano-sized III-V semiconductor devices on silicon. Both papers offer the microelectronics industry a possible answer to the long term challenge of creating a new powerful and energy efficient, yet smaller transistor to pave path for technology scaling for advanced CMOS nodes.
