Researchers from Pakistan have reported a green approach to the synthesis of graphene oxide/silver nanoparticle nanocomposite.

Metallic nanoparticles (NPs) have various benefits in the field of electrochemistry. Because of their small size, nanoparticles may enhance the contact area of the electrode in use. Furthermore, metallic nanoparticles may boost the rate of mass transfer and provide quick electron transference, increasing the sensitivities of the used electrodes. Silver nanoparticles (AgNPs) are relatively low cost and have distinct physical and chemical characteristics that make them helpful in several optical, chemical, and catalytic functions. Nanoscale composites of metallic nanoparticles and graphene oxide have promising applications in energy storage, supercapacitors, and electronics.

GamGraPhic, a Cambridge University spin out developing graphene-based photonics technology, announced a raise of £813,475 (over USD$981,000) from Wealth Club clients through the Enterprise Investment Scheme (EIS). Proceeds from the funding will be used to complete fabrication and testing of the demonstration devices.

This takes its total amount raised to £1.26 million, which has been raised through an equity funding round from existing and new investors led by Frontier IP and Wealth Club. A previous funding round, in September 2021, raised £1.6 million, valuing the company at £7.2 million.

Directa Plus has signed an extension to the commercial supply agreement with Alfredo Grassi to include Graphene Plus Thermal Planar Circuit for the workwear market in Italy and France.

The supply agreement will grant Grassi use of Directa's print textile technology for the workwear market in both countries for two years. The agreement is expected to give a significant boost to company's workwear income in 2022.

The Malaysian Rubber Council (MRC) has high hopes for its new aerospace balloon, made of a combination of graphene extract and natural rubber. The MRC's CEO, Nor Hizwan Ahmad, said the research and collaboration carried out by Meditech Gloves Sdn Bhd and Cranfield University in the United Kingdom has shown huge potential through the application of this product and findings.

The MRC CEO said the evolution from plantation to the aerospace industry is a great achievement for Malaysia’s rubber industry. He also said the aerospace balloon made of graphene extract and infused into natural rubber is new in the market and patented by Levidian Nanosystems.

LG Electronics USA has announced its 2022 lineup of TONE Free true wireless earbuds, to be rolled out in the US starting September 2022.

The flagship model, TONE Free T90, is said to deliver impressive sound thanks to several upgrades, including the use of graphene to reduce vibration. The use of graphene helps reduce vibration, while Dolby Head Tracking support keeps the feel of music around the users, even when they move.
