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 their publication in Angewandte Chemie, the authors also emphasize its photodynamic potential to selectively kill cells upon irradiation.
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 of novel optoelectronic materials, such as organic electroluminescent displays and solar cells.
New research suggests that the life of lithium-ion batteries could be more than doubled by using graphene girders at the electrodes.
Researchers from the Chinese Harbin Institute of Technology have developed an intriguing material that combines a soft, self-healing polymer with a tough layer of graphene oxide and could one day form the basis of ultra-tough scratch resistant coatings.
Researchers at Chalmers University of Technology and the Beijing University of Technology have exploited graphene’s thermoelectric properties to create a new kind of radiation detector. Classified as a bolometer, the new device has a fast response time and, unlike most other bolometers, works over a wide range of temperatures. With a simple design and relatively low cost, this device could be scaled up, enabling a wide range of commercial applications.
