Grab a coffee and your car is fully charged—this is how many people envision the future of mobility. But today’s batteries still fall short of this ideal. While modern lithium–ion batteries can charge from 20% to 80% in about 20 to 30 minutes, a full charge takes considerably longer—and fast charging puts significant stress on the cells.

A new international review study published in the journal Advanced Energy Materials now shows how lithium–sulfur batteries (LSBs) could overcome these limitations.

University of Sydney researchers have harnessed human-made lightning to develop a more efficient method of generating ammonia—one of the world’s most important chemicals. Ammonia is also the main ingredient of fertilizers that account for almost half of all global food production.

The research was published in Angewandte Chemie International edition.

The team have successfully developed a more straightforward method to produce ammonia (NH3) in gas form. Previous efforts by other laboratories produced ammonia in a solution (ammonium, NH4+), which requires more energy and processes to transform it into the final gas product.

The current method to generate ammonia, the Hab...

This triple-layer sunlight catalyst supercharges green hydrogen by 800%

The material can effectively capture the sunlight so that the energy therein can be used for hydrogen production through the photochemical water splitting reaction.Photographer:Olov Planthaber

Researchers in Sweden have developed a powerful new material that dramatically boosts the ability to create hydrogen fuel from water using sunlight, making the process eight times more effective than before. This breakthrough could be key to fueling heavy transport like ships and planes with clean, renewable energy.

The chemical reaction to produce hydrogen from water is several times more effective when using a combination of new materials in three layers, according to researchers at Linköping University in Sweden...

Light-as-a-feather nanomaterial extracts drinking water from air

An international scientific collaboration has developed a novel nanomaterial to efficiently harvest clean drinking water from water vapor in the air. The nanomaterial can hold more than three times its weight in water and can achieve this far quicker than existing commercial technologies, features that enable its potential in direct applications for producing potable water from the air.

The collaboration is led by the Australian Research Council Center of Excellence for Carbon Science and Innovation (ARC COE-CSI) UNSW Associate Professor Rakesh Joshi and Nobel Laureate Professor Sir Kostya Novoselov. Prof Joshi is based at the School of Materials Science and Engineering, University of New South Wales (UNSW). Prof Novoselov is based at the National University of Singapore.
