Nanoscale article in Chemistry World: Manipulating liquid metal marbles

22 May 2013

By Hannah Porter, Publishing Assistant.

Sequential snaptshots of a liquid metal marble in motion when a voltage is applied

Researchers in Australia and Germany have made highly controllable actuators in the form of liquid metal marbles. The marbles have a nanoparticle coating that can be electrochemically manipulated to control their movement.

Actuation involves converting an input signal into motion to drive a mechanism or system. Micro- and nano-scale actuators are crucial components in consumer electronics, amongst other things.

Now, Shi-Yang Tang, under the supervision of Kourosh Kalantar-Zadeh and Arnan Mitchell, at RMIT University, Melbourne, has demonstrated that liquid metal marbles can act as actuators in aqueous media when an electrical current is applied. The marbles consist of a galinstan (an alloy of gallium, indium and tin) core that has been coated with tungsten oxide nanoparticles. An applied current causes the nanoparticles to migrate along the surface of the galinstan, creating an asymmetry in the surface tension that makes the marbles move.

On-off temperature sensing with graphene oxide

16 May 2013

By Heather Montgomery, Deputy Editor.

Researchers in Korea have developed a new temperature sensing platform based on graphene oxide (GO). The sensor uses GO’s functionality as an efficient Förster resonance energy transfer (FRET) acceptor to deliver a fast optical on-off signal in response to temperature change.

The article describes how the scientists functionalised GO sheets with thermally-responsive triblock copolymers for the first time. The triblock copolymer brush was designed to contain a component for covalent grafting to GO, a thermally-responsive component and a fluorescent component. At elevated temperatures, the thermally-responsive component (poly(N-isopropylacrylamide) undergoes a conformational change that reduces the distance between the fluorophore and GO. This quenches the photoluminescence (PL) of the flurophore component.

The scientists tested a dispersion of the functionalised GO sensing platform in water. PL spectra showed a decrease in intensity as the temperature was increased. A marked decrease in PL intensity was evident at temperatures above 32 ^oC, demonstrating an on-off switching behaviour of the sensor. The functionalised graphene oxide composites demonstrated excellent stability in water, opening up the possibility for their use as optical indicators of temperature change in biologically and environmentally compatible sensing systems.

The expanding Universe of thiolated gold nanoclusters

10 May 2013

By Rowan Frame, Commissioning Editor.

“Thiolated gold nanoclusters form a universe of their own”, writes De-en Jiang in the first line of his recent feature article in this field. Jiang’s article provides a fascinating tour through this ever-expanding cosmos from the point of view of a computational chemist.

The expanding universe of thiolated gold nanoclusters and beyond

A great challenge for computational chemists is to predict the most stable structure for a thiolated gold nanocluster with a given composition. There are just a few experimentally resolved structures and these provide important hints for the structures of many identified compositions that have yet to be crystallised or structurally determined. Jiang describes computational approached to predict these structures, in particular the powerful “staple hypothesis”, which can help predict how the staple motifs are arranged on the core surface.

It is not fair to say that this article is simply an intergalactic tour. Jiang also further pushes the boundaries of the Universe in his article by presenting some new low-energy structures for the first time. He also discusses some imaginative ideas for future cosmic pioneering.

Nanoscale article in Chemistry World: Origami electronics

08 May 2013

By Hannah Porter, Publishing Assistant.

Lighting of an LED via folded paper printed with silver nanowire inks

We normally think of electronic components as being inflexible but researchers in Japan are challenging this concept by reinventing paper. And they’ve used their paper electronics to create origami-style lights.

Antennas transmit and receive information and although they have been put on paper before, none of these antennas have been foldable. This is because the conductive materials struggle to stay on the coarse and porous surface of the paper, resulting in deterioration of their electronic properties. Now, Masaya Nogi and co-workers at Osaka University, have combined smooth paper, made from mechanically nanofibrillated cellulose nanofibres, and silver nanowire inks to make foldable antennas. To demonstrate the effectiveness of the antennas the team folded the printed nanopaper into origami cranes and showed they could be used in the illumination of a light emitting diode.
