New graphene-based catalyst for hydrogen production could be a step toward clean fuel

Researchers at UC Santa Cruz South and the China University of Technology have developed a graphene-based nanostructured composite material that shows impressive performance as a catalyst for the electrochemical splitting of water to produce hydrogen. An efficient, low-cost catalyst is essential for realizing the promise of hydrogen as a clean, environmentally friendly fuel.

The team has been investigating the use of carbon-based nanostructured materials as catalysts for the reaction that generates hydrogen from water. In a recent study, they obtained good results by incorporating ruthenium ions into a sheet-like nanostructure composed of carbon nitride. Performance was further improved by combining the ruthenium-doped carbon nitride with graphene, to form a layered composite.

Dotz Nano enter MOU with Recochem and eyes the Australia and NZ markets

Dotz Nano is now planning to sell its graphene quantum dots into Australia and New Zealand after entering an exclusive distribution agreement with Australia-based Recochem. The agreement between the companies allows for a five-month evaluation period where the companies can explore each other’s performance in the regions’ markets, with a comprehensive agreement to be finalized by June.

Under the initial MoU, Dotz Nano will provide Recochem with samples of its graphene quantum dots for numerous applications, with sales terms to be agreed on a customer-by-customer basis.

Haydale and Talga sign a commercial supply and development agreement

Haydale logoTalga Resources logo 2017UK-based advanced materials group Haydale Graphene Industries has entered into a commercial supply and development agreement with Australian-listed Talga Resources. The agreement will see the two companies work together on the production, sales and marketing of jointly developed graphene-based transparent conductive ink products for industrial applications in Asia.

The two companies have been working together for a few years, and will now look to enhance the properties of Haydale’s graphene-based, transparent conductive ink by using Talga’s highly conductive graphitic materials. Initial tests showed that Talga’s material can enhance electrical conductivity of Haydale's transparent inks by 15% or more above that of synthetic graphite.

Graphene and hBN join to create unique ‘petri-dish’

Researchers at The University of Manchester and the NGI have shown how graphene and boron nitride can be used for observing nanomaterials in liquids, by creating a ‘petri-dish’ of sorts.

Scanning / transmission electron microscopy (S/TEM) is one of only few techniques that allows imaging and analysis of individual atoms. However, the S/TEM instrument requires a high vacuum to protect the electron source and to prevent electron scattering from molecular interactions. Several studies have previously revealed that the structure of functional materials at room temperature in a vacuum can significantly different from that in their normal liquid environment. So, it is important to be able to study the structure at the required state.

New graphene product targets audio interconnects

The audio field has been experiencing a major graphene boom recently. In addition to various existing headphones and earbuds, a graphene contact enhancer is now on the market. A new-Zealand based company called Mad Scientist Audio is selling its Graphene Contact Enhancer (GCE) that can be used on any metal-to-metal contacts, such as RCA plugs and sockets, loudspeaker leads, fuses, and so on.

The product is said to 'fill in the gaps' and give a profound improvement in system performance when applied to the important contacts in a system (e.g interconnects, speaker leads, power cords, fuses, tube pins, etc). It reportedly does not suffer from the problems that silver-based products do, namely oxidation and ability to cause short circuits.
