Graphene applications: what is graphene used for? - Page 25

Earlier this month, Hememics Biotechnologies, developer of a rapid handheld bio testing platform based on unique graphene-based sensors, raised a $2 million seed round to help build its “lab in a hand” tech. Now, Hememics Biotechnologies also entered into a strategic partnership with General Graphene Corporation, the culmination of a four-year collaborative effort to develop a scalable, non-clean-room process for the manufacturing of the company’s 32-plex, graphene biosensor chips. 

Combined with Hememics’ expertise in long-shelf-life detection biology, this partnership aims to revolutionize point-of-care diagnostics tools for pathogens and environmental toxins.

GrapheneDX, General Graphene Corporation and Sapphiros have announce a strategic partnership to industrialize graphene-based biosensors for medical devices used to diagnose a variety of diseases at the point-of-care and in consumer settings.

GrapheneDx is an in vitro diagnostics company focused on improving diagnostic capability at the point-of-care and in consumer settings. The company is an expert in functionalizing graphene to create graphene field effect transistors (GFETs), which are biosensors that can be used to detect disease in biological samples. GrapheneDx's medical devices are designed to provide lab-quality accuracy, deliver results in less than 5 minutes and be simple enough to be performed both at the point of care and by patients without the supervision of a medical professional. The company's GFET platform is versatile, demonstrating performance across a variety of disease states (sexually transmitted infections, respiratory disease, cardiac disease, concussion and others) and sample types (stool, urine, swabs, blood, etc.), with little or no sample preparation. Additionally, the platform is capable of multiplexing numerous analytes concurrently with a single patient sample. GrapheneDx's first tests will be for the diagnosis of sexually transmitted infections, including Chlamydia and Gonorrhea, using a noninvasive, easy to collect urine sample.

Researchers from Sichuan University, Chinese Academy of Sciences and Georgia Institute of Technology have developed a graphene-based wearable textile that can convert body movement into useable electricity and even store that energy. The fabric can potentially be used in a wide range of applications, from medical monitoring to assisting athletes and their coaches in tracking their performance, as well as smart displays on clothing.

The accuracy of current wearable electronic devices and various available health monitors remains limited due to the handful of locations on or near the body on which they can be placed, and restricted to a small selection of applications. In the future, if advanced fabrics can be developed, wearable electronic devices integrated into shirts, pants, underwear and hats will be able to track indicators of frailty to assess risk of age-related disease, monitor cortisol levels to track stress levels, or even detect pathogens as part of a global pandemic monitoring network. To take wearable electronics to this next level, monitors will have to be integrated into textiles in a way that is lightweight, unobtrusive and less cumbersome.

Asus has unveiled the Asus ROG Swift OLED PG49WCD, a gaming monitor that uses graphene for thermal management.

Earlier this year, Tohoku University researchers created a technique that could micro/nanofabricate silicon nitride thin devices with thicknesses ranging from 5 to 50 nanometers. The method employed a femtosecond laser, which emitted extremely short, rapid pulses of light. It turned out to be capable of quickly and conveniently processing thin materials without a vacuum environment.

By applying this method to an ultra-thin atomic layer of graphene, the same group has now succeeded in performing a multi-point hole drilling without damaging the graphene film. 

The Centre for Advanced 2D Materials (CA2DM) at the National University of Singapore (NUS), focused on the research of graphene and other 2-dimensional (2D) materials, and CBMM, a leader in niobium products and technology, have developed new niobium-graphene batteries.

The batteries are currently being tested at the new CBMM-CA2DM Advanced Battery Laboratory which was recently launched by NUS and CBMM (established with a joint investment of USD$3.8 million) over three years, supported by the National Research Foundation, Singapore.

Graphene Square Electronics has launched a crowdfunding campaign on Kickstarter to raise funds for what the Company calls "the first graphene powered appliance - Kitchen Styler".

According to Graphene Square Electronics, it is the "first and only appliance to use graphene as its sole source of heat". It is said to use CVD graphene in its design. 

Graphene Manufacturing Group (GMG) has announced the signing of a binding Joint Development Agreement ("JDA") with Rio Tinto, with the goal of accelerating the development and application of GMG's Graphene Aluminium-Ion batteries in the mining and minerals industry. Rio Tinto will contribute technical and operational performance criteria and A$6 million (over USD$3,900,000), in exchange for preferential access rights.

The JDA seeks to support the accelerated development of GMG's Graphene Aluminium-Ion Batteries for use in heavy mobile equipment and grid energy storage applications in the mining and mineral industry. The JDA builds on the existing collaboration for Rio Tinto to explore the use of GMG's Energy Saving and Energy Storage solutions (announced May 2022). This JDA is effective immediately and is expected to last 2 years with payments spread over the term of the agreement. The JDA aims to co-develop GMG's Graphene Aluminium-Ion battery pouch cell into an initial battery pack/module proof of concept.

Versarien has shared that trials of a precast concrete containing its Cementene water-based graphene mixture were shown to maintain its strength with 20% of the cement removed.

The initial results, carried out in tests at the accredited laboratory of Ireland-based Banagher Precast Concrete, “demonstrate the significant potential to reduce CO₂ emissions without impacting the performance of the concrete”, the AIM-listed company said. This is because producing 1kg of ordinary Portland cement emits around 0.8-0.9kg of CO₂ and roughly 500kg of cement is used per cubic metre of Banagher's precast concrete. Producing 1kg of Cementene is estimated to generate a higher level of CO₂ emissions, at 1.44 kg, but Versarien said because only around 5kg of Cementene is used per cubic metre of concrete and allows the removal of 20% of cement in the precast concrete mix, this would equate to a net saving of almost 73kg of CO₂ emissions per cubic metre of concrete poured.
