Towards Sustainability – from a By-product of the Biodiesel industry to a Valuable Chemical

Sustainable biodiesel and hydrogen energy cycles

One of the main waste by-products of the biodiesel industry, glycerol, can be used as a raw material for the generation of valuable dihydroxyacetone and hydrogen, the latter of which can be used as 100% clean fuel.

Scientists develop a cheap and efficient copper-based catalyst that can be used to convert glycerol, one of the main by-products of the biodiesel industry, into a valuable compound called dihydroxyacetone. In addition, this same process produces hydrogen molecules from water, and these could be used as a clean type of fuel, further highlighting the impact of this research in terms of energy sustainability.

Hydrogen (H2) is a very attractive candidate as a replacement of fossil fuels because it can be produced from water (H...

‘Superdiamond’ carbon-boron cages can trap and tap into different properties

The bipartite sodalite type clathrate structure, which consists of truncated octahedral “host” cages that trap strontium “guest” atoms, was synthesized under high-pressure and high-temperature conditions using a laser heating technique. Image is courtesy of Tim Strobel.

A long-sought-after class of “superdiamond” carbon-based materials with tunable mechanical and electronic properties was predicted and synthesized by Carnegie’s Li Zhu and Timothy Strobel. Their work is published by Science Advances.

Carbon is the fourth-most-abundant element in the universe and is fundamental to life as we know it. It is unrivaled in its ability to form stable structures, both alone and with other elements.

A material’s properties are determined by how its atoms are bonded and the structural ar...

Imagine having access to a battery, which has the potential to power your phone for five continuous days, or enable an electric vehicle to drive more than 1000km without needing to “refuel”.

Monash University researchers are on the brink of commercialising the world’s most efficient lithium-sulphur (Li-S) battery, which could outperform current market leaders by more than 4X, and power Australia and other global markets well into the future.

Lithium-ion batteries are notorious for developing internal electrical shorts that can ignite a battery’s liquid electrolytes, leading to explosions and fires. Engineers at the University of Illinois have developed a solid polymer-based electrolyte that can self-heal after damage – and the material can also be recycled without the use of harsh chemicals or high temperatures.

The new study, which could help manufacturers produce recyclable, self-healing commercial batteries, is published in the Journal of the American Chemical Society.

As lithium-ion batteries go throug...
