Researchers develop a method for photo-mechanochemical synthesis of nanographenes in the solid-state

Professor Lars Borchardt’s team at Ruhr University Bochum, Germany, has succeeded in carrying out light-driven chemical reactions in the solid-state without resorting heavily to solvents. The team stated that this provides a sustainable alternative to established synthesis methods.

Light is considered the ideal driving force of chemical reactions as it’s cheap, available in abundance and produces no waste. This is why light-driven, i.e. photochemical reactions are highly attractive for the production of chemical compounds. However, they are usually carried out in huge amounts of solvents that are often toxic and generate hazardous waste in enormous quantities. Solid-state photochemical reactions without solvents could present an alternative. However, they have hardly been feasible so far, as they could only be mixed insufficiently and so it was possible to scale them up to relevant quantities.

Researchers develop graphene/MoS2 micro-electrochemical capacitors for ultra-high charge storage

Researchers from the Indian Institute of Science have developed ultramicro-electrochemical capacitors with two-dimensional (2D) molybdenum disulphide (MoS2) and graphene-based electrodes. The development has great potential for wearables and implantable electronics as well as for sensors and miniature “smart” technology. 

The miniature energy storage device uses graphene Flakes and MoS2 alternately in each electrode - the cathode and anode. Gel was used as the electrolyte, which makes it possible to integrate micro-supercapacitors into chips. This would be difficult if not impossible with a water-soluble electrolyte. The capacitor showed a capacitance of 1.8 mF/cm2 for a single-layer structure (graphene-MoS2). The multilayer electrode structure, consisting of multiple alternating layers of graphene and molybdenum disulfide, gained 30 times greater capacitance, or 54 μF/cm2.

Researchers develop a graphene-based intelligent, wearable artificial throat that is sensitive to human speech and vocalization-related motions

A team of researchers at China's Tsinghua University and Shanghai Jiao Tong University have developed a graphene-based intelligent, wearable artificial throat (AT) that is sensitive to human speech and vocalization-related motions. It is a wafer-like tool one centimeter square that can allow barely audible sounds, or even whispers, to be converted into speech at normal volume.

The device is about the width of plastic cling wrap. The 25-micrometer deep device may be applied to one's throat with a simple adhesive. Tiny wires connect to a microcontroller powered by a coin-sized battery.

HydroGraph signs LOI for a graphene-batteries project with CGT and LOLC

HydroGraph Clean Power, manufacturer of graphene and other nanomaterials, has announced a letter of intent (LOI) to form a partnership with Ceylon Graphene Technologies (CGT) via LOLC Advanced Technologies (LOLC AT), which owns a majority share of CGT through a joint venture with Sri Lanka Institute of Nanotechnology (SLINTEC).

The partnership will center around a novel composite graphene blend that is said to improve the charge acceptance of lead acid batteries by 47%. HydroGraph and LOLC AT agreed to commercialize this product and pursue the lead acid battery market, projected to be worth more than $47 billion by 2030, driven in part by electric vehicle dependency on the product.

Researchers develop method for optimizing both the growth and the transfer process of graphene

A team of researchers from the University of Cambridge, RWTH Aachen University and the National Institute for Materials Science in Japan has developed a methodology for simultaneously optimizing the growth and the transfer process of graphene, showing that it is possible to dry-transfer graphene with high-yield, if the crystallographic orientation of the growth surface is chosen appropriately.

Graphene often needs to be transferred from the growth substrate (typically copper) to a final substrate where components can be built. However, current transfer approaches either lead to a substantial degradation of the crystal quality or are not compatible with high-volume manufacturing. Moreover, while graphene has great potential for next generation electronics, the gap between the performance of “hero devices” realized in research labs and what can be reproducibly fabricated with scalable approaches remains large. This is why high-end electronic devices enabled by graphene are still not on the market – and why scalability is such a challenge in terms of making the most of this nanomaterial.

Researchers combine pMINFLUX, graphene energy transfer and DNA-PAINT for a super-resolution microscopy method for rapid differentiation of molecular structures in 3D

A team of researchers, led by Ludwig-Maximilians-University (LMU) chemist Prof. Philip Tinnefeld, has combined 2D MINFLUX microscopy with a new method for axial resolution. This combination, which exploits the special properties of graphene, enables an axial precision of less than 3 angstroms.

It was only a few years ago that a resolution limit in optical microscopy which seemed fundamental was broken, when researchers overcame the resolution limit of around 250 nanometers (winning the 2014 Nobel Prize in Chemistry for their efforts). Since then, the methods of microscopy have progressed rapidly.

Researchers' examination of surface oxygen in graphene materials may yield graphene-based products with better antibacterial activity

The amount of surface oxygen in graphene materials is a key factor in how effective they could be in killing bacteria – a discovery which may help to design safer and more effective products to combat antimicrobial resistance.

Researchers from the UK's University of Birmingham, China's Shandong University of Technology, Chinese Academy of Sciences and National Center for Nanoscience and Technology of China, NovaMechanics in Cyprus, Austria's Medical University of Innsbruck, University of Eastern Finland and Leiden University in the Netherlands have found that it is graphene oxide’s different interaction modes that lead to distinct antibacterial activity – with a ‘switch’ occurring when surface oxygen levels reach a certain threshold.
