First Graphene, Breedon Group, Morgan Sindall Construction and the University of Manchester develop graphene-enhanced cement

First Graphene will work with the Breedon Group, Morgan Sindall Construction & Infrastructure and the University of Manchester to develop a new reduced-CO2 graphene-enhanced cement. The consortium is currently formulating the cement using varying doses of First Graphene’s PureGRAPH graphene-enhanced grinding aid. The project received a research grant from the UK government earlier in 2022.

First Graphene says that the study involves one of the largest commercial trials of its kind to date globally.

Researchers show that hydrodynamic electrons flow through materials without electrical resistance

Scientists from Israel's Weizmann Institute of Science, in collaboration with teams at Manchester University and UC Irvine,  have shown that an electronic fluid can flow through materials without any electrical resistance, thereby perfectly eliminating a fundamental source of resistance that forms the ultimate limit for ballistic electrons. This result could open the door to improved electronic devices that do not heat up as much as existing technologies.

When electrons flow in electrical wires, they lose part of their energy, which is wasted as heat. This heating is a major problem in everyday electronics. The heating occurs because electrical conductors are never perfect and have a resistance for the flow of electrical currents. Typically, this resistance originates from the scattering of the flowing electrons by imperfections in the host material. But it stands to reason that a perfect conductor, devoid of any imperfections, would have zero resistance. However, even if the conductor is perfectly clean and free from imperfections, the resistance does not vanish. Instead, a new source of resistance emerges, known as the Landauer-Sharvin resistance. In an electrical conductor, electrons flow in quantum channels, much like cars in highway lanes. Similar to highway lanes, each electronic channel has a finite capacity to conduct electrons, limited by the quantum of conductance. For a given conductor, the number of quantum channels is finite and determined by its physical width. Thus, even a perfect electronic device, devoid of any imperfections, will never have infinite conductance. It will always have resistance. In the absence of interactions between electrons, this Landauer-Sharvin resistance is unavoidable, putting a fundamental lower bound on the heating of computer chips, which becomes even more severe as transistors become smaller.

Graphene enables highly efficient and selective extraction of gold

Scientists from The University of Manchester, Tsinghua University in China and the Chinese Academy of Sciences (CAS) recently reported that graphene can facilitate gold extraction from waste containing only trace amounts of gold (down to billionth of a percent).

This surprising application of graphene was described to work quite straightforwardly: add graphene into a solution containing traces of gold and, after a few minutes, pure gold appears on graphene sheets, with no other chemicals or energy input involved. After this you can extract your pure gold by simply burning the graphene off. The research shows that 1 gram of graphene can be sufficient for extracting nearly 2 grams of gold.

Researchers capture images of atoms ‘swimming’ in liquid

Graphene scientists from The University of Manchester have created a novel ‘nano petri dish’ using two-dimensional (2D) materials to create a new method of observing how atoms move in liquid. The team, led by researchers based at the National Graphene Institute (NGI), used stacks of 2D materials including graphene to trap liquid in order to further understand how the presence of liquid changes the behavior of the solid.

Graphene scientists capture first images of atoms ‘swimming’ in liquid image

The researchers were able to capture images of single atoms ‘swimming’ in liquid for the first time. The findings could have widespread impact on the future development of green technologies such as hydrogen production.

Researchers design graphene nanocomposite temperature alarm sensor

Researchers from The University of Manchester and Hubei University have integrated the electrical conductivity of graphene and the insulation of nitrocellulose to prepare a fire alarm sensor.

Researchers design graphene/nitrocellulose composite alarm image

The graphene/nitrocellulose membrane remains electrically insulated in normal condition, but instantly turns conductive at high temperatures: Upon encountering flames, nitrocellulose decomposes rapidly as a reaction to the high temperature and induces a distinct transition in its electrical resistance, causing the transformation process of the alarm sensor from being electrically insulated to an electron conductive state.
