An interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Australia has developed a safer and more sustainable approach to extract and recover gold from ore and electronic waste.

Explained in the leading journal Nature Sustainability, the gold-extraction technique promises to reduce levels of toxic waste from mining and shows that high purity gold can be recovered from recycling valuable components in printed circuit boards in discarded computers.

In summary, this review provides a comprehensive picture of how low-dimensional perovskite materials could revolutionize memory devices and computing, which is expected to inspire new ideas and discussions in the near future.

How can we accelerate the energy transition in a socially responsible way? Empa researchers propose a publicly funded basic service in solar energy that would increase energy autonomy, create social justice and promote further investment in renewable energies. This requires – among other things – a third of all roofs in Switzerland and a total investment every 30 years that is roughly equivalent to the average gross monthly salary per Swiss citizen.

The researchers developed a green and simple method to synthesize a silica aerogel that integrates two contrasting functional groups including methyl and amine. The aerogel not only has high adsorption capacity for low-concentration CO₂ but also possesses excellent thermal insulation performance under humid and high-temperature conditions.

Researchers have developed a new flexible material that can attenuate radar signals using tree bark waste as core raw source. The innovative material combines silicone rubber with sustainable carbon derived from tree bark, resulting in an eco-friendly alternative to traditional, high-cost technologies. Despite being made from natural waste, the new material can perform just as well as expensive nanocarbons, offering a greener and more affordable option to attenuate electromagnetic signals.
