HydroGraph and EMP Shield to collaborate on graphene-based EMI shielding

HydroGraph Clean Power has announced its collaboration with Kansas-based EMP Shield Inc., a company focused on protecting devices from destructive electromagnetic interference. Under this collaboration, the HydroGraph and EMP Shield are developing advanced electromagnetic interference (EMI) shielding using HydroGraph’s high-purity graphene.

Electronic equipment can be protected from EMI by conductive or absorptive materials and coatings. HydroGraph and EMP Shield are working together to develop coatings and insulated barriers to protect electronic devices by blocking unwanted disruptions or transmission of electronic data.

Directa Plus secures big sludge treatment contract with Romanian steel producer

Directa Plus has announced that Setcar SA, its environmental services subsidiary, has signed a three-year contract with Liberty Galati, the largest integrated steel producer in Romania, to process oily mills sludge.

The contract will last for three years and has a total value of €5.5 million, with the potential for further expansion up to a total of €8.0 million. Under the terms of the agreement, Setcar will provide solutions for the treatment of oily mills scale produced in the manufacturing of steel.

Directa said the contract would enable Setcar to expand further its waste treatment and disposal services for industrial pollutants and broaden the range of applications for the group’s Grafysorber technology. By using Grafysorber, Setcar would allow Liberty Galati to recycle a considerable amount of oily sludge waste, transforming it into a raw material suitable for reuse in steel production.

Universal Matter receives support from NETL

Earlier this year, Universal Matter acquired Applied Graphene Materials' assets for $1.3 million and then AGM changed its company name to Universal Matter GBR. Now, Universal Matter received support from The National Energy Technology Laboratory (NETL) Carbon Ore Processing Program through a cooperative agreement. 

The company has demonstrated a novel graphene production technology called Flash Joule Heating (FJH), which can transform carbonaceous material feedstocks, including coal and coal-wastes, to high quality graphene.

Researchers develop 'golden rules' for controlling alignment of supermoiré lattices

Researchers from Singapore's National University of Singapore (NUS) and Japan's National Institute for Materials Science (NIMS) have formulated 'golden rules' for controlling the alignment of supermoiré lattices. 

Moiré patterns are formed when two identical periodic structures are overlaid with a relative twist angle between them or two different periodic structures but overlaid with or without twist angle. The twist angle is the angle between the crystallographic orientations of the two structures. For example, when graphene and hexagonal boron nitride (hBN) which are layered materials are overlaid on each other, the atoms in the two structures do not line up perfectly, creating a pattern of interference fringes, called a moiré pattern. This results in an electronic reconstruction. The moiré pattern in graphene and hBN has been used to create new structures with exotic properties, such as topological currents and Hofstadter butterfly states. When two moiré patterns are stacked together, a new structure called supermoiré lattice is created. Compared with the traditional single moiré materials, this supermoiré lattice expands the range of tunable material properties allowing for potential use in a much larger variety of applications.

First Graphene, Halocell and QUT secure funding for graphene-enhanced perovskite PV project

First Graphene has announced an R&D collaboration with Greatcell Energy, trading as Halocell Energy, and the Queensland University of Technology (QUT) to commercialize perovskite solar cell fabrication. The project has received a Cooperative Research Centers Project (CRC-P) grant worth over AUD$2 million (around $USD1,300,000).

The research and development project is intended to commercialize ultra-low-cost, flexible perovskite solar cell fabrication using Halocell’s roll-to-roll production process at the company’s Wagga Wagga plant, First Graphene said in an announcement. Through the project, First Graphene plans to develop cost-effective graphene-based electrode replacements for high-cost conductor materials, such as gold and silver, used in cell manufacturing.

NanoXplore and VoltaXplore announce an agreement for supply of battery cells to a "well-known commercial vehicle OEM"

NanoXplore and its wholly owned subsidiary, VoltaXplore, a silicon-graphene-enhanced Li-ion battery manufacturer for the Electric Vehicle and grid storage markets, have announced that VoltaXplore has agreed on commercial terms for the supply of Li-ion battery cells with a well-known commercial vehicle OEM. 

The batteries include graphene in the anode (graphene-silicon additives) and battery cells will reportedly be produced in VoltaXplore’s gigafactory starting from 2026. The agreement is for 1 GWh per year for a duration of 10 years following a pricing formula that passes through raw material cost to the customer.
