Haydale Graphene Industries has announced the conclusion of the auction process for its subsidiary, Haydale Ceramic Technologies LLC, which was placed into Chapter 11 bankruptcy to stop cash flow drain and maximize shareholder value. Despite initial interest, geopolitical tensions and trade issues affected the auction, resulting in a sale to Greenleaf Corporation for approximately $680,000. The outcome aligns with Haydale’s strategy to reduce overhead costs and improve profitability, ensuring the protection of its core business.

Researchers from Fudan University in China have used graphene to create the world’s fastest flash memory, which performs about 25 billion operations per second.The device, called "PoX", takes 400 picoseconds (0.0000000004 sec) to store one bit of information. Usually, traditional static and dynamic RAM (SRAM, DRAM) records data at a speed of 1 to 10 nanoseconds, but does not retain information in the event of a sudden power outage. Flash drives don’t need a power source to store data, but they take micro and milliseconds to store, which is too slow for modern artificial intelligence accelerators that send terabytes of data in real time.

A research team develops high-power, high-energy-density anode using nano-sized tin particles and hard carbon.

Zentek has announced the completion of the Innovative Solutions Canada - Testing Stream contract for ZenARMOR™ nano-pigment in military grade, chromate-free corrosion protection aerospace paint systems, and a new collaboration with Jazeera Paints Company for continued product development and testing.ZenARMOR™ was evaluated in commercial non-chromate aviation paint systems developed by PPG and Akzo Nobel. Three rounds of corrosion testing were completed from September 2023 to July 2024 and testing followed ASTM B117 (salt spray) and ASTM D5894 (cyclical corrosion) standards. The tests were reportedly successful in demonstrating the effectiveness of ZenARMOR™ nano-pigments in inhibiting corrosion of the aluminum alloy AA2024-T3.

United Utilities has joined forces with climate tech company Levidian to demonstrate the potential of using biogas produced from wastewater to create hydrogen and graphene at its wastewater treatment works.The trial is taking place at Manchester Bioresources Centre, part of Davyhulme Wastewater Treatment Works, where modern-day sewage treatment processes were initially developed back in 1914. Levidian’s LOOP device uses electromagnetic waves to split methane gas into hydrogen and carbon, capturing the carbon in solid form as graphene. The lower carbon blend gas is then fed into United Utilities’ onsite generator where it is burned to help power the site.

Researchers from France's LPICM and Université Paris-Saclay have designed new graphene-based OLED emitters that outperform previous graphene emitters.The researchers designed green emitters based on rod-shaped nanographene materials containing C60-tBu8 materials, and incorporated these into a benchmark OLED device. The OLED devices containing the C60-tBu8 exhibited current and power efficiencies (CE and PE) of 2.27 cd·A–1, 0.28 lm·W–1 and luminance of 164 cd·m–2.

Directa Plus recently stated that its subsidiary had secured an extension to its original framework agreement with OMV Petrom, which has been going on for several years and has generated over €1.0 million in revenues to date.The AIM-listed company said the scope of the new agreement includes the treatment of up to 40,000m³ of sludge/emulsion, and up to 25,000m³ of water, as well as the supply of adsorbent barriers and pillows for containment and absorption.

Zentek has announced the signing of a collaboration agreement (effective April 11, 2025) with Filtration Solutions Industrial Co. (“FSCO”), a leading Saudi-based manufacturer and distributor of air filtration products, to manufacture and distribute ZenGUARD™ Enhanced Air Filters across the Gulf Cooperation Council (“GCC”) region.Under the terms of the agreement, Zentek will supply FSCO with HVAC filter media coated with its proprietary graphene-silver-based ZenGUARD™ technology — known for its ability to significantly increase viral filtration efficiency. FSCO will produce ZenGUARD™ Enhanced Air Filters that will be marketed and distributed under Zentek’s branding throughout the GCC, including Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Bahrain, and Oman, with the net revenue generated from sales of the products shared between Zentek and FSCO. The term of the agreement is for three years, with additional renewal options.

Researchers from Korea's Kyungpook National University and Dongguk University recently addressed common challenges presented by current lithium-ion batteries, by engineering materials at the nanoscale. Their work focuses on a novel hybrid material designed to maximize the synergistic effects of its components.  Image credit: Chemical Engineering Journal The composite is a hierarchical heterostructure that combines reduced graphene oxide (rGO) with nickel-iron layered double hydroxides (NiFe-LDH). This unique composite leverages the properties of its components: rGO provides a conductive network for electron transport, and the nickel-iron-oxide components enable fast charge storage through a pseudocapacitive mechanism. The key to this innovative design is the abundance of grain boundaries, which facilitate efficient charge storage.

A team of researchers at École Polytechnique Fédérale de Lausanne (EPFL) recently developed a scalable technique to create porous graphene membranes that selectively filter CO₂ from gas mixtures. Their approach is said to reduce production costs while improving membrane quality and performance, paving the way for real-world applications in carbon capture and beyond. Image from: Nature Chemical EngineeringGraphene membranes are excellent at separating gases because they can be engineered with pores just the right size to let CO₂ through while blocking larger molecules like nitrogen. This makes them ideal for capturing CO₂ emissions from power plants and industrial processes. But there’s a catch: manufacturing these membranes at a meaningful scale has been difficult and costly.

Researchers from Monash University and The Pennsylvania State University, In collaboration with NematiQ, a wholly owned subsidiary of Clean TeQ Water, have developed a novel water filtration membrane that effectively removes small PFAS molecules (a group of man-made chemicals known for their persistence and resistance to breakdown), overcoming a significant challenge faced by conventional water filters. PFAS cycle. Image credit: Clean TeQ WaterThe team designed a beta-cyclodextrin (βCD) modified graphene oxide (GO-βCD) membrane with nanoscale channels that selectively retain PFAS while allowing water to pass through.

Scientists have developed a scalable method to produce porous graphene membranes that efficiently separate carbon dioxide. The breakthrough could significantly reduce the cost and footprint of carbon capture technology.

In the quest to design the next generation of materials for modern devices -- ones that are lightweight, flexible and excellent at dissipating heat -- a team of researchers made a discovery: imperfection has its upsides.

Researchers have developed an innovative solution to a pressing environmental challenge: removing and destroying per- and polyfluoroalkyl substances (PFAS), commonly called 'forever chemicals.' A new study unveils a method that not only eliminates PFAS from water systems but also transforms waste into high-value graphene, offering a cost-effective and sustainable approach to environmental remediation.
