Bringing plasmonic color to solid materials Researchers at the University of California, Riverside, used silver nanoparticles (AgNPs) to produce plasmonic color-switchable films for solid materials. This effect was previously achieved only in liquids. Rapid and reversible tuning of plasmonic color in solid films, a challenge until now, holds great promise for a number of applications,” sa... » read more

Textiles for energy storage Scientists at RMIT University developed a way to laser print waterproof textiles with graphene supercapacitors for embedded energy storage. The process takes three minutes to create a 10x10cm patch. The electronic textile is based on nylon coated with PDMS on one side for waterproofing. The other side was paint coated with graphene oxide and a binder to form thin... » read more

Everything’s faster in Texas The Frontera supercomputing system was formally unveiled last week at the Texas Advanced Computing Center. The system was deployed in June on the University of Texas at Austin campus. It is the fifth-fastest supercomputer in the world at present and the world's fastest academic supercomputer. Dell EMC and Intel collaborated on fitting out Frontera. Work beg... » read more

A ring of 18 carbon atoms Scientists at IBM Research – Zurich and Oxford University write about allotropes of carbon – the many versions of atomic carbon formations, such as diamonds and graphite. “Carbon, one of the most abundant elements in the universe, can exist in different forms - called allotropes - giving it completely different properties from color to shape to hardness. For... » read more

July’19 Startup Funding
By Jeff Dorsch - 07 Aug, 2019 - Comments: 0

During the month of July, 21 technology startups took in mega-rounds of $100 million or more. Those companies together received more than $7.5 billion. On the other end of the financing spectrum, dozens of startups got seed funding or a Series A round. The dollar amounts were much smaller. Still, they are the beating heart of entrepreneurship around the world. It also was a month when som... » read more

Superconductivity seen in trilayer graphene Stanford University and University of California at Berkeley researchers discovered signs of superconductivity in stacking three-layer sheets of graphene, they report. “It’s definitely an exciting development,” says Cory Dean, a physicist at Columbia University. Dean notes that bilayer graphene superconducts only when the atomic lattices of ... » read more

Creating 2D Compounds
By Katherine Derbyshire - 18 Jul, 2019 - Comments: 1

A 2D material, by definition, has no surface dangling bonds. A bulk material with plate-like structure, such as graphite, is composed of thin layers with a weakly bonded cleavage plane between. What this means is a monolayer of graphite will seek to satisfy its exposed dangling bonds by absorbing other materials. A monolayer of graphene, in contrast, is energetically complete without a secon... » read more

Wearable heart monitoring Researchers at the University of Texas at Austin developed a lightweight, stretchy heart monitoring patch that can be worn externally. Along with being easy to wear, the graphene-based 'e-tattoo' is more accurate than existing electrocardiograph machines, according to the team. The e-tattoo measures cardiac health using both electrocardiograph and seismocardiograph... » read more

2D straintronics Researchers at the University of Rochester and Xi’an Jiaotong University dug into how 2D materials behave when stretched to push the boundaries of what they can do. "We're opening up a new direction of study," says Stephen Wu, assistant professor of electrical and computer engineering and physics at Rochester. "There's a huge number of 2D materials with different properti... » read more
