A recently published study led by Virginia Commonwealth University researchers sheds new light on how water interacts with the nanomaterial graphene, a single, thin layer of carbon atoms arranged in a hexagonal honeycomb lattice.

The researchers’ findings could hold implications for a variety of applications, including sensors, fuel cell membranes, water filtration, and graphene-based electrode materials in high-performance supercapacitors.

The study, “Solvent–Solvent Correlations across Graphene: The Effect of Image Charges,” was published in the American Chemica...

Researchers are pushing the boundaries of data speed with a brand new type of organic LED. An international research team, involving Newcastle University experts, developed a visible light communication (VLC) setup capable of a data rate of 2.2 Mb/s by employing a new type of organic light-emitting diodes (OLEDs).

To reach this speed, the scientists created new far-red/near-infrared, solution-processed OLEDs. And by extending the spectral range to 700-1000 nm, they successfully expanded the bandwidth and achieved the fastest-ever data speed for solution-based OLEDs.

Described in the journal Light Science & Applications, the new OLEDs create opportunities for new internet-of-things (IoT) connectivity, as well as wearable and implantable biosensors technol...

Mechanical control and modulation of light on a silicon chip could enhance lidar. Researchers have built a way that lidar could achieve higher-resolution detection of nearby fast-moving objects through mechanical control and modulation of light on a silicon chip.

A self-driving car has a hard time recognizing the difference between a toddler and a brown bag that suddenly appears into view because of limitations in how it senses objects using lidar.

The autonomous vehicle industry is exploring “frequency modulated continuous wave” (FMCW) lidar to solve this problem...

Scientists are a step closer to developing a fast and cost effective camera that utilises terahertz radiation, potentially opening the opportunity for them to be used in non-invasive security and medical screening.

A research team led by Professor Emma Pickwell-Macpherson from the University of Warwick Department of Physics and involving Rayko Ivanov Stantchev and scientists from the Department of Electronic Engineering at The Chinese University of Hong Kong has reached a crucial milestone towards developing single-pixel terahertz imaging technology for use in biomedical and industrial applications.

Their single-pixel terahertz camera reached 100 times faster acquisition than the previous state-of-the-art without a...
