Sugar coating opens a path to low cost lithium sulfur batteries

Offering the potential to:

  • Drive an electric vehicle from Melbourne to Sydney on a single charge
  • Create lightweight batteries for drones and submarines
  • Unlock new avenues in aviation and maritime industries
  • Produce batteries in Australia with Australian lithium, without using cobalt and rare earth minerals.

Simply by adding sugar, researchers from the Monash Energy Institute have created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries that are essential for aviation, electric vehicles and submarines.

The Monash team, assisted by CSIRO, report in today’s edition of Nature Communications that using a glucose-based additive on the positive electrode they have managed to stabilise lithium-sulfur battery technology, long touted as the basis for the next generation of batteries.

“In less than a decade, this technology could lead to vehicles including electric buses and trucks that can travel from Melbourne to Sydney without recharging. It could also enable innovation in delivery and agricultural drones where light weight is paramount,” says lead author Professor Mainak Majumder, from the Department of Mechanical and Aerospace Engineering and Associate Director of the Monash Energy Institute.

Galaxies pump out contaminated exhausts

Research reveals how star-making pollutes the cosmos

Animation available, astronomers available in Australia and UK for interview

Galaxies pollute the environment they exist in, researchers have found.

A team of astronomers led by Alex Cameron and Deanne Fisher from the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) used a new imaging system on at the WM Keck Observatory in Hawaii to confirm that what flows into a galaxy is a lot cleaner than what flows out.

The research is published today in The Astrophysical Journal.

Can you find the owls in the night? Researchers recruiting Hoot Detectives

Nationwide project aims to map Australia’s favourite predator birds

“I heard the owl scream and the crickets cry.” Macbeth, William Shakespeare.

Is that an owl hooting? Or a car?

Researchers are after volunteers to help map five native Australian owl species, by listening to short recordings made in the bush. 

The results will provide important information about the range and numbers of these beloved birds of prey. They will also help researchers develop artificial intelligence (AI) systems to use in a new field of science, known as “eco-acoustics”.

The project is called Hoot Detective, and is produced by ABC Science in collaboration with the Australian Acoustic Observatory (A2O) for National Science Week. It will commence online on Monday 9 August at www.hootdetective.net.au and run until the end of August.

New type of massive explosion explains mystery star

‘Magneto-rotational hypernova’ soon after the Big Bang fuelled high levels of uranium, zinc in ancient stellar oddity

A massive explosion from a previously unknown source – 10 times more energetic than a supernova – could be the answer to a 13-billion-year-old Milky Way mystery.

Astronomers led by David Yong, Gary Da Costa and Chiaki Kobayashi from Australia’s ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) based at the Australian National University (ANU) have potentially discovered the first evidence of the destruction of a collapsed rapidly spinning star – a phenomenon they describe as a “magneto-rotational hypernova”.

Where does it hurt, Rover?

Adelaide invention revolutionises veterinary x-rays

Your best friend can’t tell you where it hurts but now, thanks to an invention by Adelaide company Micro-X, vets have a better tool to diagnose your pet’s health problems.

The Micro-X Rover, a mobile x-ray machine was first designed for the Australian military as an ultra-mobile battlefield-ready x-ray machine delivering the full spectrum of imaging solutions.

It has now been adapted to be used by vets, using custom software tailored for small animal exams by Micro-X’s US partner Varex Imaging Corporation.

Bend it like Einstein: Astronomers turn galaxies into magnifiers

New technique helps NASA’s James Webb Space Telescope

Astronomers have turned a cluster of galaxies into a gargantuan magnifying lens, using it to study another galaxy, 10.7 billion light years away, in unprecedented detail.

Taking advantage of a phenomenon known as “gravitational lensing”, the team of scientists, led by NASA Goddard Space Flight Centre scientist Dr Soniya Sharma, identified star forming regions in the distant and ancient galaxy.

The research was funded by Australia’s ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D), and will be of direct benefit to NASA’s next orbiting observer.

Without the use of the massive magnifying effect, the galaxy, dubbed cswa128, would be a tiny blur to even the most powerful telescopes on Earth. With it, the astronomers can see stars being formed just three billion years after the Big Bang.

Milky Way not unusual, astronomers find

Detailed cross-section of another galaxy reveals surprising similarities to our home

The first detailed cross-section of a galaxy broadly similar to the Milky Way, published today, reveals that our galaxy evolved gradually, instead of being the result of a violent mash-up. The finding throws the origin story of our home into doubt.

The galaxy, dubbed UGC 10738, turns out to have distinct ‘thick’ and ‘thin’ discs similar to those of the Milky Way. This suggests, contrary to previous theories, that such structures are not the result of a rare long-ago collision with a smaller galaxy. They appear to be the product of more peaceful change.

And that is a game-changer. It means that our spiral galaxy home isn’t the product of a freak accident. Instead, it is typical.

Stronger materials for bigger turbines

The Danish wind turbine company Vestas is teaming up with Australian scientists to develop stronger carbon fibre composite materials to be used in reinforcing turbine blades.

Updated for Europe Day, 7 June 2021

Vestas has funded two years of research at Deakin University’s Carbon Nexus facility in Geelong into strengthening carbon fibre.

The investment is part of a project to build two wind farms in Victoria that together will deliver more than 500 megawatts, enough to power 350,000 homes.
