A major breakthrough in liquid catalysis is transforming how essential products are made, making the chemical manufacturing process faster, safer and more sustainable than ever before.

Researchers from Monash University, the University of Sydney, and RMIT University have developed a liquid that could transform chemical production across a range of industries—from pharmaceuticals and sustainable products to advanced materials.

By dissolving palladium in liquid gallium the team, led by Associate Professor Md. Arifur Rahim from Monash University’s Department of Chemical and Biological Engineering, created a self-regenerating catalytic system with unprecedented efficiency.

Hydrogen is increasingly gaining attention as a promising energy source for a cleaner, more sustainable future. Using hydrogen to meet the energy demands for large-scale applications such as utility infrastructure will require transporting large volumes via existing pipelines designed for natural gas.

But there’s a catch. Hydrogen can weaken the that these pipelines are made of. When hydrogen atoms enter the steel, they diffuse into its microstructure and can cause the metal to become brittle, making it more susceptible to cracking. Hydrogen can be introduced into the steel during manufacturing, or while the pipeline is in service transporting oil and gas.

To better understand this problem, researcher Tonye Jack used the Canadian Light Source (CLS) at the University of Saskatchewan (USask) to capture a 3D view of the cracks formed in steels. Researchers have previously relied on two-dimensional imaging techniques, which don’t provide the same rich detail made possible with synchrotron radiation.

Chibueze Amanchukwu wants to fix batteries that haven’t been built yet. Demand for batteries is on the rise for EVs and the grid-level energy storage needed to transition Earth off fossil fuels. But more batteries will mean more of a dangerous suite of materials used to build them: PFAS, also known as “forever chemicals.”

“To address our needs as a society for electric vehicles and energy storage, we are coming up with more ,” said Amanchukwu, Neubauer Family Assistant Professor of Molecular Engineering in the UChicago Pritzker School of Molecular Engineering (UChicago PME). “You can see the dilemma.”

PFAS are a family of thousands of chemicals found in batteries but also everything from fast food wrappers and shampoo to firefighting foam and yoga pants. They keep scrambled eggs from sticking to pans and rain from soaking into jackets and paint, but the same water resistance that makes them useful also make them difficult to remove when they get into the water supply. This earned them the nickname “forever chemicals.”

Researchers at the Georgia Institute of Technology have developed a new technology to manufacture solar cells.

Solar energy is growing rapidly in the United States. In 2010, it accounted for 0.1% of electrical generation in the country and has increased to over 6% in 2024. By 2029, solar is slated to become the largest source of renewable energy.

Most commercial solar panels are made from silicon. Producing solar panels like this is energy-intensive and can be difficult to do within the United States. For solar to take off more in the United States, we need to find a less expensive, more available material.

The oceans hold an enormous amount of very diluted uranium that could potentially serve as a sustainable fuel source for nuclear power. But how can uranium be extracted quickly and efficiently from seawater?

Balancing high selectivity for ions with rapid transport of those ions has long been a major challenge in obtaining uranium from the sea. Now a groundbreaking study suggests a solution.

A research team led by Prof. Wen Liping from the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences has developed a biomimetic adsorbent that can attract and hold uranium ions. The inspiration for this adsorbent is the natural porous structure of the spiky, globular fruit of the Chinese sweetgum tree, Liquidambar formosana. The team’s findings were recently published in Matter.

Photovoltaic (PV) solutions, which are designed to convert sunlight into electrical energy, are becoming increasingly widespread worldwide. Over the past decades, engineers specialized in energy solutions have been trying to identify new solar cell designs and PV materials that could achieve even better power conversion efficiencies, while also retaining their stability and reliably operating for long periods of time.

The many emerging PV solutions that have proven to be particularly promising include tandem based on both perovskites (a class of materials with a characteristic crystal structure) and organic materials. Perovskite/organic tandem solar cells could be more affordable than existing silicon-based solar cells, while also yielding higher power conversion efficiencies.

These solar cells are manufactured using wide-bandgap perovskites, which have an electronic bandgap greater than 1.6 electronvolts (eV) and can thus absorb higher-energy photons. Despite their enhanced ability to absorb high-energy light particles, these materials have significant limitations, which typically adversely impact the stability of solar cells.

Last month, DARPA published a call for proposals on how to “grow” massive biological structures in space. It’s not as crazy as it sounds: The space race is heating up outside of the weird space biology sector. Some startups are building self-assembling space habitats, others are working on spaceports, and the ISS’s successor is in development. Let’s take a look.
