In 2015, scientists at James Cook University in Queensland, Australia, and collaborators from institutions in Australia, Singapore, Japan, and the US developed a technique for growing graphene from tea tree extract. Now, scientists from James Cook University developed a process to synthesize graphene from tangerine peel oil, which they then used to recover silver from waste PV material. To demonstrate the quality of the recovered silver and the synthesized graphene, they made a dopamine sensor that reportedly outperformed reference devices.

The team synthesized “freestanding” graphene using non-toxic and renewable tangerine peel oil that can reportedly be used for the recovery of silver from end-of-life organic PV devices. The researchers said that their process result in high-quality graphene and demonstrated a remarkable ability to selectively recover silver from photovoltaic waste. One of the most surprising findings, according to the team, was how selective the graphene was in targeting silver.

Chang Robotics, an engineering company, and Northwestern University’s INVO Lab have announced a joint venture aimed at reducing contamination from microplastics and poly-fluoroalkyl substances (PFAS) in the US food supply.  

This collaboration has led to the development of GOEco, an initiative that shows that very small amounts of graphene oxide can be infused into paper products or compostable packaging materials to replace plastic and PFAS. GOEco’s primary goal is to replace the widespread use of plastics in food packaging, such as paper plates and disposable utensils. The patent-pending technology helps enhance the environmental friendliness of disposable tableware without compromising functionality.

Researchers have used a specially crafted electric potential to manipulate the electronic band structure of graphene, laying the groundwork for on-demand electronic band design. 

Scientists have long been trying to tune the electronic band structures of materials so that those materials exhibit desired physical properties. In the past few years, researchers have shown they can manipulate the band structures of graphene and other 2D materials using electric-field configurations that produce simple periodic potentials. Now, Changgan Zeng at the University of Science and Technology of China and his colleagues have shown that they can achieve greater control over the band structure using an electric potential with a shape that resembles a basket-weaving pattern known as kagome.

Khalifa University of Science and Technology’s Research & Innovation Center for Graphene and 2D Materials (RIC2D), through its commercial arm spinoff company INTRATOMICS™, and LOLC Advanced Technologies Australia, a subsidiary of the Sri Lanka-based LOLC Group, have announced their collaboration following an agreement on the development of graphene-related products for precision applications.

The joint production of graphene in commercial quantities and development of advanced materials manufacturing marks this phase of the partnership as INTRATOMICS™ and LOLC Advanced Technologies Australia consolidate their roles in this agreement following the earlier MoU signed in August 2023.

Premier Graphene has announced that "one of the world’s largest materials handling company" invited Premier Graphene to permit them to test and separately confirm HGI's proprietary hemp-based graphene formulation in concrete with respect to which it has a distribution license in the United States.

Impressed with the 32% improvements to the tensile strength of Premier’s and HGI’s initial engineering report, performed by Baja California Test S.A. de R.L. de C.V. This major materials handling, production and manufacturing company is performing independent tests to confirm the previous results.

Graphene Manufacturing Group (GMG) has provided a progress update on its Graphene Aluminium-Ion Battery technology ("G+AI Battery") being developed by GMG and the University of Queensland ("UQ").

The Company is currently optimizing the G+AI Battery pouch cell electrochemistry. The challenges that the G+AI Battery are showing through this phase of its maturation are very similar to other battery chemistries that have been developed into mass production - including Lithium-Ion batteries. The performance of the pouch cells will be communicated upon successfully producing a repeatable and 3^rd party tested 1000 mAh+ battery pouch cell. 

GraphEnergyTech, developer of a process to integrate graphene electrodes into solar cells to replace silver, has announced a £1 million (over USD$1.2 million) equity raise to accelerate development and scale up of its advanced high-conductivity graphene electrodes.

The fundraising was led by Aramco Ventures, the corporate venturing arm of Aramco, a leading integrated energy and chemicals company.

A group of civil engineering technology students who worked on a research project at the Southern Alberta Institute of Technology (SAIT) in Calgary has found that adding a certain amount of graphene to concrete can make the material more impermeable to water and increase the strength of the mix.

The students tested the concrete by pouring slabs for a sidewalk and, after conducting a number of freeze-thaw and compressive assessments, found the strength of the material was significantly increased.
