An international team of researchers reports the development of a graphene-based optical modulator that proves outstanding performances in modulation efficiency, stability and high speed.
Scientists have suggested using innovative thin films to considerably reduce friction and thus increase the durability of surfaces in mechanisms. This discovery can be important for many fields, from medicine to space technologies.
A research team has developed a transparent amorphous silicon that transmits visible light - which permits us to distinguish the colors of objects - enabling the development of paper-thin lenses usable in head-mounted displays that show virtual and augmented reality images in real time.
Scientists looked into the latest research to find the most exciting potential applications of graphene in point-of-care tests. This includes diagnostic tests for SARS-CoV-2, the virus responsible for COVID-19, but also detecting other viruses, bacteria and even cancerous tumours.
In January 2021, Nanosurf acquired Scuba Probe Technologies, a startup company that develops atomic force microscopy probes for electrical measurements in liquid.
By creating kinks in the structure of graphene, researchers have made the nanomaterial behave like a transistor, and have shown that when a strip of graphene is crinkled in this way, it can behave like a microchip, which is around 100 times smaller than conventional microchips.
A major challenge in the development of implantable and ingestible biomedical electronic devices is the limited lifetime of their power sources. The energy requirements of these devices are highly dependent on their application and the complexity of the required electrical systems. The power unit, which is composed of one or more energy sources - batteries, energy-harvesting, and energy transfer - as well as power management circuits, supplies electrical energy to the whole system.
Researchers have demonstrated that nanoengineered biodegradable microcapsules can guide the development of hippocampal neurons in an in vitro experiment. The microcapsules deliver nerve growth factor, a peptide necessary for neuron growth.
Researchers detail how they developed a nano-barrier and custom-built deposition system that bonds to the surface of polymer or composite materials, protecting them from erosion in low-Earth orbit.
Injecting patients with a gel that would dissolve over several months could replace the need to administer daily or weekly shots. But to make this possible, researchers first had to create a Jello-like substance that could defy one of the fundamental laws of nature.
The 'sloshing' of a quantum fluid comprised of light and matter reveals superfluid properties. A team of physicists have successfully created sloshing quantum liquids in a 'bucket' formed by containment lasers.
