Graphene Concrete 30% Stronger in Commercial Project

In May, 2021, UK construction company Nationwide Engineering laid the world’s first graphene-enhanced concrete slab engineered for sustainability in a commercial setting. The new Southern Quarter gym in Amesbury’s Solstice Park opened in summer 2021. This is a joint venture between Nationwide Engineering and The University of Manchester. The addition of tiny amounts of graphene …

Circuit Design Claimed to Harvest Tiny But Infinite Power From Brownian Motion

At room temperature, micron-sized sheets of freestanding graphene are in constant motion, even in the presence of an applied bias voltage. University of Arkansas researchers collecting the displacement current using a nearby small-area metal electrode and present an Ito-Langevin model for the motion coupled to a circuit containing diodes. Numerical simulations show that the system …

Buckling Magnetic Graphene Will Make Many Gadgets and Nanorobots

Buckling in graphene mimics the effect of colossally large magnetic fields that are unattainable with today’s magnet technologies. Graphene buckles when cooled while attached to a flat surface. Buckling, magnetic graphene can be a platform for stretchable electronics with many important applications, including eye-like digital cameras, energy harvesting, skin sensors, health monitoring devices like tiny …

Light-induced Propulsion of Graphene-on-grid Sails in Microgravity

ESA-backed researchers demonstrate the laser-propulsion of graphene sails in microgravity. In an article recently published in Acta Astronautica, they report a scalable design that minimizes the overall sail mass and hence increases their thrust upon light irradiation. In addition, they prove the new sail concept by accelerating prototypes in a free-fall facility with 1W-lasers, reaching …

Graphene Terahertz Telescopes Will be Thousands of Times Better Than Current Thz Telescopes

Currently superconductors are used for Terahertz telescope detects but new graphene terahertz detectors will use less than 0.1% of the power. Instead of microwatts, the graphene detectors could use 0.1 nanowatts. If a superconducting detector could produce a single pixel then new graphene detectors could have 1000 to 10000 pixels. Above – ​The image depicts …

Graphene Chip Reaches the Level of a 1979 Zilog Z8000

Max Shulaker and a group of researchers he leads has developed a working 16-bit microprocessor built from over 14,000 carbon nanotube transistors that is the most complex ever demonstrated. The techniques they have come up with can be implemented with equipment used for making conventional silicon chips, which means chipmakers won’t have to invest in …

Graphene-lined Clothing Could Prevent Mosquito Bites

Graphene sheets can block the signals mosquitos use to identify a blood meal, potentially enabling a new chemical-free approach to mosquito bite prevention. Researchers showed that multilayer graphene can provide a two-fold defense against mosquito bites. The ultra-thin yet strong material acts as a barrier that mosquitoes are unable to bite through. At the same …

Graphene Still Difficult to Use and Path to Major Commercialization is Uncertain

Graphene has a lot of potential because it can be the strongest material and has many other exceptional characteristics. There has been a lot of research around the material since 2004, when Professor Sir Andre Geim and Professor Sir Kostya Novoselov of the University of Manchester discovered and isolated a single atomic layer of carbon …

Tuning Graphene Superconductivity

A Columbia University-led team has developed a new method to finely tune adjacent layers of graphene—lacy, honeycomb-like sheets of carbon atoms—to induce superconductivity. Above – Applying pressure to twisted bilayer graphene transforms the material from a metal to a superconductor. Image: Ella Maru Studio “Our work demonstrates new ways to induce superconductivity in twisted bilayer …
