Materials Horizons Outstanding Paper Awards 2018

11 Sep 2019

By Jane Chan, Editorial Assistant.

Outstanding paper – Materials Horizons

Bioinspired hierarchical composite design using machine learning: simulation, additive manufacturing, and experiment

Grace X. Gu, Chun-Teh Chen, Deon J. Richmond and Markus J. Buehler, Mater. Horiz., 2018, 5, 939–945, DOI: 10.1039/CiMH00653A

In this outstanding paper, the authors propose an innovative approach to design hierarchical materials using machine learning trained with a database of hundreds of thousands of structures from finite element analysis, together with a self-learning algorithm for discovering high-performing materials where inferior designs are phased out for superior candidates. They say that their new approach can aid in the discovery and fabrication of new material designs with an orders of magnitude increase in computational eﬃcacy over conventional methods.

Runner-up – Materials Horizons

Reverse gear makes metamaterial stand out

11 Apr 2019

By Kate Bandoo, Publishing Assistant.

Article written by Emma Lockyer

Engineers have made a metamaterial that can change its shape and properties, then fully return to its original configuration on demand.

Metamaterials have properties that do not occur in natural materials. However, these properties are typically fixed.

Now, Howen Lee from the State University of New Jersey, US, and his colleagues have used 3D printing to make a shape memory polymer lattice out of acrylic acid crosslinked with bisphenol A ethoxylate dimethacrylate that is both geometrically reconfigurable and mechanically tunable.

Lanthanide macrocycle complexes endow graphene electronics with unprecedented stability

18 Mar 2019

By Kate Bandoo, Publishing Assistant.

Article written by Amy Southall|

Scientists in India have made graphene field-effect transistors that work for over 10 months with some help from discrete inorganic structures. The approach has led them to produce a graphene logic inverter that is stable in ambient conditions.

Conventional electronics tend to be silicon based, due to the ease of doping silicon with either electrons or holes. These two forms of silicon, n- and p-type, are the building blocks of electronic devices. However, it isn’t possible to make silicon electronics on the nanoscale, so many researchers are turning to materials like graphene.

An essential component of digital electronics is a logic inverter – a device for switching between fixed voltage levels. Inverters combine n-type field effect transistors and p-type field effect transistors, so require both n-type and p-type graphene.

Electrochromic devices reinvented with hydrogel layer

11 Sep 2018

By Kate Bandoo, Publishing Assistant.

Scientists in China have made a rewritable electrochromic display using a hydrogel for the first time.

Typical electrochromic devices contain upwards of five layers, their complicated structures contributing to high production costs and hindered performance. Now, a team led by Hong Wang of Xi’an Jiaontong University has devised a much simpler structure.

A lithium chloride electrolyte endows the hydrogel electrode with high ionic conductivity

Their system contains a multifunctional hydrogel deposited directly on a tungsten oxide film on top of an F-doped SnO₂ (FTO) layer. To make this possible, the researchers embedded the hydrogel with aqueous lithium chloride, allowing it to simultaneously act as a transparent electrode, electrolyte and ion storage layer. By reducing the number of interfaces present in the device, the team were able to improve the performance of the device for display applications, compared to other electrochromic systems, while also reducing production costs.

Pressure washer method for making graphene

19 Jul 2018

By Hannah Kerr, Deputy Editor.

New process generates high quality 2D crystals in minutes

Liquid-phase exfoliation of layered crystals

For few- and single-layered materials like graphene to be industrially useful there needs to be a scalable, cheap and reproducible way to produce them. Now, scientists in Italy have come up with a new exfoliation process that meets all of these requirements.

Francesco Bonaccorso and co-workers from the Italian Institute of Technology propose what they call a high pressure wet-jet-milling process to, essentially, blast apart layers of materials like graphite. A hydraulic mechanism and piston generate up to 250MPa of pressure to push a mixture of the bulk material dispersed in solvent through five different disks. The disks are interconnected and perforated with tiny adjustable holes (0.3–0.1mm diameter), which generate colliding jet streams. A similar idea is already used in industry to pulverise drugs or paints.

The major advantage here is that it takes only minutes to produce high quality 2D crystals that would take hours to make by other methods: it takes less than 3 minutes to make 1g. The resulting dispersions of 2D crystals are shown to be usable for inkjet printing and in battery anodes without needing a purification step.
