On the way to cell-type materials
On the way to cell-type materials
Molecular machines control a sizeable number of fundamental processes in nature. Embedded in a cellular environment, these processes play a central role in the intracellular and intercellular transportation of molecules, as well as in muscle contraction in humans and animals. In order for the entire organism to function, a well-defined orientation and arrangement of the molecular machines is essential.

Fresh hope for new flystrike control method
Fresh hope for new flystrike control method
Tiny nanoparticles less than a thousandth of a millimetre in size are providing a promising new method to protect sheep against deadly flystrike, according to University of Queensland research. Senior Research Fellow Dr Peter James from UQ's Centre for Animal Science said nanotechnology could be part of the solution to a problem that costs the Australian sheep industry $173 million a year.

'Hot' graphene reveals migration of carbon atoms
’Hot’ graphene reveals migration of carbon atoms
The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the material is heated on a microscopic hot plate.

New research partnership to address corrosion under insulation
PETRONAS Research Sdn Bhd (PRSB) and Curtin University have entered into a research partnership to jointly address one of the costliest forms of corrosion in the oil, gas and petrochemical industries. In line with both parties' sustainability goals, the collaboration strives to discover innovative solutions for corrosion mitigation to reduce carbon footprint and operational expenditure.

Levitating objects with sound could revolutionise virtual reality and 3D printing
Using sound to levitate something when there are other objects in the way has been shown for the first time by UCL researchers and could lead to advances in the manufacturing and entertainment sectors. The findings open up possibilities for more advanced interactive entertainment through virtual reality and mixed reality at theme parks, arcades and museums.

Stimulate light emission and measure temperature with ultrasound
Stimulate light emission and measure temperature with ultrasound
If mechanoluminescent materials are subjected to mechanical stress from outside, they emit visible or invisible light. Such excitation can occur, for example, through buckling or gentle pressure, but also completely contact-free via ultrasound. In this way, the effect can be triggered remotely and light can be brought to places that normally tend to be in the dark - for example, in the human body.

World's first ultra-fast photonic computing processor using polarisation
World’s first ultra-fast photonic computing processor using polarisation
New research uses multiple polarisation channels to carry out parallel processing - enhancing computing density by several orders over conventional electronic chips. In a paper published in Science Advances , researchers at the University of Oxford have developed a method using the polarisation of light to maximise information storage density and computing performance using nanowires.

Graphene dust not harmful
Graphene dust not harmful
Graphene-based particles released from polymer composites after abrasion induce negligible health effects. Under the leadership of Empa, an international research team of the Graphene Flagship project conducted a study on the health risks of graphene-containing nanoparticles and recently published the results in Journal of Hazardous Materials.

Embracing recycled textile and sustainable washing
Yearly we produce 110 million tons of textile waste, that is 13 kg per person globally. How can we motivate consumers to buy recycled goods and pay a higher price for these? But next to waste, we should look at how we wash our textile goods. Washing textiles is a major route for microplastics entering the environment.

A biological super glue from mistletoe berries?
A biological super glue from mistletoe berries?
Each mistletoe berry can produce up to two metres of a gluey thread called viscin. It allows the seeds of this parasitic plant to stick to and infect host plants. Since ancient times, mistletoe berries have been explored as treatments for everything from infertility and epilepsy to cancer. But, until now, no one has fully investigated the potential medical or technical uses of the glue itself.

Researchers envision wood-derived, self-powered biosensors for wireless devices
Researchers envision wood-derived, self-powered biosensors for wireless devices
Wood-derived materials can be used to harvest electrical energy from everyday movements such as walking, according to University of Toronto and University of Waterloo researchers. In a new study recently published in Nano Energy , the team demonstrated the use of lignocellulosic nanofibrils - derived from tree bark - in a prototype self-powered device capable of sending a wireless signal to a smartphone via bluetooth.

On the road to the super-battery
On the road to the super-battery
A research team led by the Technical University of Munich (TUM) has taken an in-depth look at the internal workings of batteries during charging and discharging. Their findings may help optimize charging processes. When an electric car is being charged, the charge indicator moves quickly at first, be then much more slowly at the end.

'Fruitcake' structure observed in organic polymers
’Fruitcake’ structure observed in organic polymers
Researchers have analysed the properties of an organic polymer with potential applications in flexible electronics and uncovered variations in hardness at the nanoscale, the first time such a fine structure has been observed in this type of material. The field of organic electronics has benefited from the discovery of new semiconducting polymers with molecular backbones that are resilient to twists and bends, meaning they can transport charge even if they are flexed into different shapes.

Avatar against food waste
Avatar against food waste
Around one third of all food worldwide ends up in the trash bin instead of on our plate. With the help of digital twins, researchers at Empa and Stellenbosch University are now aiming to reduce food waste, for example in the case of citrus fruits, along the production and supply chains. The hygrothermal measurement data needed to improve the shelf life of oranges and the like would actually be available.

Low-cost battery-like device absorbs CO2 emissions while it charges
Low-cost battery-like device absorbs CO2 emissions while it charges
Researchers have developed a low-cost device that can selectively capture carbon dioxide gas while it charges. Then, when it discharges, the CO2 can be released in a controlled way and collected to be reused or disposed of responsibly. We found that that by slowly alternating the current between the plates we can capture double the amount of CO2 than before Alexander Forse The supercapacitor device, which is similar to a rechargeable battery, is the size of a two-pence coin, and is made in part from sustainable materials including coconut shells and seawater.
