Researchers recently identified the atomic structure of a group of perovskite-related materials with interesting 2-D conductive properties. These strontium niobate compounds show promise for developing advanced electronics because of their ‘quasi-1-D metallic conductivity.
A team of researchers has created an ultra-stretchable sensor for smart wearables. The sensor is made by infusing graphene nanoflakes into a rubber-like adhesive. The device went through more than 10,000 cycles of stretching and relaxing while maintaining its electrical stability.
Using their own specially designed form of graphene called ‘Graphair’, CSIRO scientists have supercharged water purification. The new filtering technique makes purification simpler, more effective, and quicker.
Scientists from 25 research institutions and industries in 12 different European countries have completed one of the first attempts to understand the risks nanomaterials carry throughout their life-cycle, starting from their fabrication and ending in being discarded or recycled.
Engineers from UCLA and other institutions have designed a super-efficient and long-lasting electrode for supercapacitors. The device’s design was inspired by the structure and function of leaves on tree branches, and it is more than 10 times more efficient than other designs.
Researchers from RMIT University in Melbourne Australia have developed an ultra-thin coating that responds to heat and cold, opening the door to smart windows. The self-modifying thin coating automatically letts in more heat when it’s cold and blocks the sun’s rays when it’s hot.
Researchers have developed a new way to improve lithium ion battery efficiency. Through the growth of a cubic crystal layer, the scientists have created a thin and dense connecting layer between the electrodes of the battery.
Researchers have found a new way to curb some of the potential dangers of lithium-ion batteries. Their plating technology could solve issues of repeated lithium deposition/dissolution during charge/discharge and eventually achieve a compact, high-capacity battery.
Researchers in Japan have developed a way to recover environmental heat with a type of thin-film thermoelectric cell, based on two different materials that show changes in their redox potential on cycling of temperature.
A new ultrathin, elastic display can show the moving waveform of an electrocardiogram recorded by a breathable, on-skin electrode sensor. Combined with a wireless communication module, this integrated biomedical sensor system can transmit biometric data to the cloud.
A team of researchers has recently introduced a new biosensing contact lens capable of detecting glucose levels in patients with diabetes. The innovative smart lens has built-in pliable, transparent electronics that can monitor glucose levels from tears in the eye.
University of Washington engineers have turned tissue paper into a new kind of wearable sensor that can detect a pulse, blink of an eye, and other human movement. The sensor is light, flexible, and inexpensive, with potential applications in health care and more.
A new injectable gel delivery system forms a non-inflammatory depot that can continuously release drug carriers for months at a time after a single administration. The gel itself re-assembles into the nanocarriers, so no residual material remains after the drug is delivered.
Material scientists have created a ‘durable and washable, concrete-like’ composite material made from antibacterial copper nanoparticles. They have also developed a way of binding the composite to wearable fabric materials.
Researchers report a pre-clinical study showing that they could potentially reduce pain and recovery time with the aid of specialized nanotechnology. The team developed liposomal nanoparticles containing collagenase that could make it easier to shift teeth with braces.
