Graphjet Technology has announced it will begin trading on Nasdaq under the ticker symbol “GTI". Graphjet Technology, developer of patented technologies to produce graphite and graphene directly from agricultural waste, and Energem Corp. (Nasdaq: ENCP, ENCPW), have closed a business combination that "creates the only pure-play publicly traded direct biomass-to-graphite company.

Graphjet has raised $5.8 million through the transaction and anticipates that additional fundraising will be necessary to accelerate its growth strategy and expand its manufacturing capacity. These funds will enhance the Company’s financial flexibility as well as its ability to capitalize on organic and inorganic growth opportunities.

Archer Materials has designed a miniaturized version of its Biochip graphene field effect transistor ("gFET") chip for fabrication at a commercial foundry.

The Archer Biochip contains a sensing region of which the gFET is the core component. Each gFET chip contains multiple gFETs, each of which is a transistor, which acts as a sensor. Archer has miniaturized the total chip size by redesigning the layout of the circuits creating these gFET transistors. The new miniaturized design has been sent to a foundry partner for a whole-wafer fabrication of reduced size gFET chips, which Archer intends to integrate with other parts of the Biochip technology.

UK-based graphene developer Haydale announced its interim financial results the first half of fiscal year 2024, that ended on December 2023. The company's revenues grew by 38% to £2.47 million, and its net loss reduced to £1.61 million (from £1.89 million in H1 FY23).

Haydale plans to continue with its cost savings plan, to further hone its operations, and the company says it continues to boost its key customer commercial progress on the functionalization powder element of its business.

Graphene Manufacturing Group (GMG) has announced it will be implementing a strategic organizational restructuring to reduce operating costs, while maintaining focus on key business objectives including graphene production, energy-saving product revenue, next-generation battery development, and supply chain enhancement.

The organizational overhaul is expected to cut operating costs by A$4.5 million (almost USD$3 million) per annum, according to a statement by the company.

Versarien has announced that it has entered into an agreement with MCK Tech to sell the Group's plant and equipment in South Korea for a total consideration of £604,000, together with an exclusive license agreement with MCK Tech for the use of five patents, owned by the Group, for additional fees.

The Company continues to pursue its stated turnaround strategy, an integral part of which is to dispose of non-core businesses and assets. The plant and equipment acquired from Hanwha Aerospace in South Korea in 2020 were identified as non-core and marketed for sale. The Group's mature businesses, AAC Cyroma Limited and Total Carbide Limited, continue to be marketed for sale and the Company is progressing discussions with a number of interested parties, though the timing of any further asset sales and the quantum of the funds that may be received remains uncertain.

Researchers from China's Zhengzhou University, Ningbo University and Jilin University have used nanodiamonds as precursors to make centimeter-sized diamond/graphene composites under moderate pressure and temperature conditions (12 GPa and 1,300 to 1,500 °C). The composite is reportedly able to conduct electricity while maintaining its ultra-hardness.

This work could pave the way for realizing large-sized diamond-based materials with ultrahigh electrical conductivity and superior mechanical properties under moderate synthesis conditions, which will facilitate their large-scale applications in a variety of fields.

Solidion Technology, an advanced battery technology solutions developer, began trading on NASDAQ (ticker symbol “STI”) on February 5, 2024. Solidion is the merged entity between Honeycomb Battery Company (HBC, Dayton, Ohio) and Nubia Brand International Co., a special purpose acquisition company (SPAC), based in Dallas, Texas.

Some see electric vertical takeoff and landing (eVTOL) aircraft as the next urban transportation technology breakthrough. At the heart of an eVTOL aircraft is a heavy battery pack. The amount of energy that can be stored in a battery pack with a reduced mass must be significantly increased before the eVTOL industry can literally take off. It is estimated that eVTOL aircraft needs a battery system with a gravimetric energy density > 400 Wh/kg. For an air taxi to carry more passengers, a battery cell energy density higher than 450 or even 500 Wh/kg will be required.
