Graphene Manufacturing Group (GMG) has reported that due to higher demand, its previously announced marketed offering has been increased from AUD$2 million (around USD$1,295,000) to AUD$3.024 million (about USD$1,960,000).

The proceeds of the offering will be used to strengthen GMG’s financial position and provide liquidity to its ongoing operations, including expenses related to its research and development objectives.

Black Swan Graphene has announced the commercialization of a new product, the GraphCore family of graphene nanoplatelets products. These products, now in full production volume, are tailored to meet a diverse range of needs within the polymer industry, offering various forms including powders and polymer-ready masterbatches.

According the the Company, in addition to double-digit tensile property improvements with less than 1.0% loading, performance enhancements seen at global customer industrial trials include:

* 25% weight reduction with 1.5% loading in TPU;
* More than 20% impact resistance improvement in PP at 0.2% loading; and
* More than 40% improvement in barrier properties in PLA at 1.0% loading.

Advanced Graphene Development (AMD) has announced two significant contract extensions with its US Government customers. 

Its Radar mitigation project with the US Army continues under a new funding award whilst its novel laser blocking technology work, under contract with the Irregular Warfare Technology Support Directorate (IWTSD) is also extended. Both projects will continue throughout 2024.

Researchers from Pohang University of Science and Technology (POSTECH), Korea Institute of Industrial Technology and Konkuk University have reported the development of a small-scale energy storage device capable of stretching, twisting, folding, and wrinkling.

Micro supercapacitors (MSCs) have emerged as a promising candidate for deformable energy storage, due to high-power density, rapid charging, and long cycle life. However, the fabrication of interdigitated electrode patterns capable of maintaining the energy storage performance under repeated stretching and twisting has remained a great challenge, because brittle materials like gold (Au) have been commonly used as an electrode.

An international team of researchers, led by the University of Manchester, has achieved robust superconductivity in high magnetic fields using a newly created one-dimensional system. Achieving superconductivity in the quantum Hall regime has been a longstanding challenge, which this recent work aimed to address. 

The team followed the conventional route where counterpropagating edge states were brought into close proximity to each other. However, this approach was found to be limited. “Our initial experiments were primarily motivated by the strong persistent interest in proximity superconductivity induced along quantum Hall edge states,” explained University of Mnchester's Dr. Barrier, the paper’s lead author. “This possibility has led to numerous theoretical predictions regarding the emergence of new particles known as non-abelian anyons.”

Premier Graphene, a global advanced materials company with a focus on research, production and marketing of eco-friendly graphene, has announced achievements in the integration of graphene with construction materials.  

According to the Company, recent in-house studies have showcased the high quality of graphene-enhanced hydraulic concrete. The findings reportedly point to an unparalleled improvement in the cement’s performance, leading to products of superior quality concrete. This graphene-infused cement exhibits enhanced resistance and strength, alongside quicker drying times, which collectively contribute to considerable cost savings on large-scale construction projects.

Researchers from the University of Göttingen, Japan's National Institute for Materials Science and Massachusetts Institute of Technology (MIT) have demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be "switched" on and off, which has potential for developing tiny, energy-efficient transistors. 

Among its many unusual properties, graphene is known for its extraordinarily high electrical conductivity due to the high and constant velocity of electrons travelling through this material. This unique feature has made scientists try to use graphene for faster and more energy-efficient transistors. The challenge has been that to make a transistor, the material needs to be controlled to have a highly insulating state in addition to its highly conductive state. In graphene, however, such a "switch" in the speed of the carrier cannot be easily achieved. In fact, graphene usually has no insulating state, which has limited graphene's potential a transistor.
