For more than two millennia, paper has been a staple of human civilization. But these days, the use of paper is not limited to writing. It is also playing a pivotal role in ushering in a greener future.

Lightweight and thin paper-based devices help reduce dependence on metal or plastic materials, while at the same time being easier to dispose of...

Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.

An international team of researchers from the University of Nottingham’s School of Chemistry, University of Birmingham, University of Queensland, and University of Ulm have designed a material made up of copper anchored on nanocrystalline carbon nitride.

The copper atoms are nested within the nanocrystalline structure, which allows electrons to move from carbon nitride to CO2, an essential step in the production of methanol from CO2 under the influence of solar irradiation...

The 2023 Nobel Prize in Chemistry was focused on quantum dots – objects so tiny, they’re controlled by the strange and complex rules of quantum physics. Many quantum dots used in electronics are made from toxic substances, but their nontoxic counterparts are now being developed and explored for uses in medicine and in the environment. One team of researchers is focusing on carbon- and sulfur-based quantum dots, using them to create safer invisible inks and to help decontaminate water supplies.

The researchers will present their results today at the spring meeting of the American Chemical Society (ACS).

Quantum dots are synthetic nanometer-scale semiconduc...

Scientists have developed a sustainable method to make high-performance plastics from agricultural leftovers, turning them into valuable materials.

In our rapidly industrialized world, the quest for sustainable materials has never been more urgent. Plastics, ubiquitous in daily life, pose significant environmental challenges, primarily due to their fossil fuel origins and problematic disposal.

Now, a study led by Jeremy Luterbacher’s team at EPFL unveils a pioneering approach to producing high-performance plastics from renewable resources.

The research, published in Nature Sustainability, introduces a novel method for creating...
