New method enables materials that combine graphene and metals

Researchers from CNR-IOM, University of Milano-Bicocca, University of Trieste and University of Vienna have developed a method to create new materials that combine the extraordinary properties of single metal atoms with the robustness, flexibility, and versatility of graphene.

The method involves the controlled deposition of metal atoms, such as cobalt, during the formation of the graphene layer on a nickel surface. Some of these atoms are incorporated into the carbon network of graphene, creating a material with exceptional properties of robustness, reactivity, and stability even under critical conditions.

Art and science combine to create graphene-enhanced clay artwork

Researchers at the National University of Singapore (NUS), and Deliarts recently presented an interdisciplinary approach combining materials science, ultrasonication, artistic expression, and curatorial practice to develop graphene-enhanced ceramics, improving strength and aesthetics. The focus of the approach was incorporating graphene oxide (GO) into kaolin clay and exploring its effects on material properties.

In recent years, scientists have been adding GO to ceramic slurries — consisting of particles of kaolin clay or other materials dispersed in water — to make fired ceramics more durable and resistant to thermal shock. The team adapted this technique by using ultrasound to better mix the GO into kaolin slurries. They adjusted GO concentration and ultrasound exposure time to find the conditions that most enhanced the resulting ceramics’ strength and heat resistance. The team also collaborated with artist-in-residence Delia Prvački, who created works from the new ceramic material that are on display at the National University of Singapore Museum.

Graphene oxide and chitosan sponge for ultrafast and precise recovery of gold from electronic waste

Researchers at the National University of Singapore, working with colleagues from Manchester University and Guangdong University of Technology, have developed a sponge-like material made of graphene oxide and chitosan, that can be used to extract gold from electronic waste. In their recent study, the research team describes how they made their sponge and how well it worked during testing.

Previous research has shown that removing gold, silver and other metals from electronic equipment that is no longer useful, as a way to recycle such materials, is a difficult task that often results in low yields and the generation of a variety of toxic pollutants. In this new work, the team has found a way to remove the gold in a way that is cheaper and cleaner than conventional methods and much more efficient as well.

Memsift Innovations acquires graphene membrane technology from Singapore’s Ngee Ann Polytechnic

Singapore-based Memsift Innovations has entered into a technology transfer agreement with Singapore’s Ngee Ann Polytechnic on an innovative graphene membrane technology.

It was explained that the technology, featuring graphene oxide-based hollow fiber ultrafiltration and nanofiltration membranes, was developed based on over a decade of research and development. The ultrafiltration technology utilizes a graphene oxide-block copolymer composite renowned for its exceptional chemical and thermal stability, making it ideal for harsh industrial applications. Its unique surface chemistry forms a protective water layer that effectively prevents fouling. The nanofiltration technology employs a robust single-layer modified graphene oxide membrane with synthetic water channels, enhancing selectivity and permeability. This enables efficient molecular-level separation and differentiation between monovalent and multivalent ions.
