Tiny bubbles on electrodes key to speeding up chemical processes
Formation of bubbles on electrodes, usually thought to be a hindrance, can be beneficial
14-Dec-2020
New Curtin University-led research has shown the formation of bubbles on electrodes, usually thought to be a hindrance, can be beneficial, with deliberately added bubbles, or oil droplets, able to accelerate processes such as the removal of pollutants such as hydrocarbons from contaminated water ...
New butterfly-inspired hydrogen sensor is powered by light
Light-activated sensor delivers precision results at room temperature: For medical applications and hydrogen economy
07-Dec-2020
Inspired by the surface of butterfly wings, researchers have developed a light-activated hydrogen sensor that produces ultra-precise results at room temperature. The technology can detect hydrogen leaks well before they pose safety risks and can measure tiny amounts of the gas on people's breath, ...
Making biodiesel from dirty old cooking oil just got way easier
New ultra-efficient catalyst can recycle old cooking oil into biodiesel and turn food scraps into high-value complex molecules
28-Oct-2020
Researchers have developed a powerful, low-cost method for recycling used cooking oil and agricultural waste into biodiesel, and turning food scraps and plastic rubbish into high-value products. The method harnesses a new type of ultra-efficient catalyst that can make low-carbon biodiesel and ...
Nano-microscope gives first direct observation of the magnetic properties of 2D materials
Discovery means new class of materials and technologies
22-Sep-2020
Australian researchers and their colleagues from Russia and China have shown that it is possible to study the magnetic properties of ultrathin materials directly, via a new microscopy technique that opens the door to the discovery of more two-dimensional (2D) magnetic materials, with all sorts of ...
Novel approach improves graphene-based supercapacitors
Meeting growing demand for increased storage capacity
06-Aug-2020
Demand for integrated energy storage devices is growing rapidly as people rely more and more on portable and wireless electronics, and the global need grows for clean energy sources such as solar and wind energies. This is creating an exponential need for advanced energy storage technologies - ...
Keep safe and cool in the pool
Novel chip sensor quickly and continuously does all the work of a chemistry laboratory
03-Aug-2020
A new microchip that enables continuous monitoring of pH and chlorine levels in swimming pools will vastly improve water safety and hygiene for more than 2.7 million Australians as new research shows it can deliver consistent and accurate pool chemistry for reliable pool management. Developed by ...
Serendipity broadens the scope for making graphite
New technique does not require the typical metal catalysts or special raw materials to turn carbon into crystalline graphite
28-Jul-2020
Curtin University researchers have unexpectedly discovered a new way to make crystalline graphite, an essential material used in the making of lithium ion batteries. Described in a research paper published in Nature's Communications Materials, the new technique does not require the typical metal ...
Engineers use electricity to clean up toxic water
Powerful electrochemical process destroys water contaminants, such as pesticides
10-Jul-2020
A team of engineers may be one step closer to cleaning up heavily contaminated industrial wastewater streams. Researchers from the School of Chemical and Biomolecular Engineering developed an electrochemical oxidation process with the aim of cleaning up complex wastewater that contained a toxic ...
Easy as playing with Lego: Neat way to turn waste carbon dioxide into useful industrial products
Making catalysts has been expensive and complicated – until now
16-Jun-2020
Chemical engineers from UNSW Sydney have developed new technology that helps convert harmful carbon dioxide emissions into chemical building blocks to make useful industrial products like fuel and plastics. And if adopted on a large scale, the process could give the world breathing space as it ...
Light from stretchable sheets of atoms for quantum technologies
Largest spectral, color-tuning range from an atomically thin quantum system demonstrated
20-Apr-2020
The researchers say their results, using an atomically thin material, hexagonal boron nitride, constitute a significant step forward in understanding light-matter interactions of quantum systems in 2D materials, and the journey towards scalable on-chip devices for quantum technologies. The study ...
