Researchers of the ICN2 Nanobioelectronics and Biosensors Group led by Prof. Arben Merkoçi have devised a simple manufacturing method for versatile graphene oxide-based micromotors. Requiring no special equipment, it can be used to produce a range of micromotors that can be further tuned for different purposes. Luis Baptista-Pires explains the process in the paper published […]
Graphene photodetectors from Emberion Oy convert light to an electronic signal using graphene charge transducers combined with a nanocrystal light absorber. The photodetectors provide responsivity and low noise over a broad spectral range from VIS to NIR/SWIR wavelengths without cooling below room temperature. The full dynamic range is 160 dB, owing to the low noise and […]
Graphene is made commercially from graphite as multi layers of nanoplates. The highest quality graphene is monolayer however this is expensive to make. A new process has been developed that can make monolayer graphene with very high yield, all it takes is a drop of honey.
With the worsening of the oil-product pollution problem, oil–water separation has attracted increased attention in recent years. In this study, a porous three-dimensional (3D) carbon aerogel based on cellulose nanofibers
Graphene is a remarkable material: light, strong, transparent and electrically conductive. It can also convert heat to electricity. Researchers have recently exploited this thermoelectric property to create a new kind of radiation detector.
Graphene and its nano-sized little sibling, nanographene, are well known for their remarkable photoelectronic properties. However, biomedical applications are hampered by the insolubility of the materials, especially in water. A Japanese team of scientists has now introduced substituted “warped nanographene,” which is soluble in a broad range of solvents while maintaining its photophysical properties. In […]
Researchers in Japan have found a way to form two materials, each made of three layers of graphene. Each material’s graphene is stacked differently and has unique electrical properties. Their work has implications for the development of novel electronic devices, such as photo sensors that convert light into electrical energy.
A team of Chinese scientists has developed graphene-based high temperature-resistant memristors, which are leading candidates for future storage and neuromorphic computing, with potential to address existing challenges in the development of electronic devices.
Researchers at Washington State University are working on graphene-based sodium-ion batteries that might provide a less expensive, viable alternative to lithium-ion batteries.
Nanographenes are attracting wide interest from many researchers as a powerful candidate for the next generation of carbon materials due to their unique electric properties. Scientists at Nagoya University have now developed a fast way to form nanographenes in a controlled fashion. This simple and powerful method for nanographene synthesis could help generate a range […]
