Major funding milestone for world-first prototype fusion plant

The government has announced a record £2.5 billion investment in fusion energy, which includes support for a prototype fusion energy plant in Nottinghamshire.

The new prototype plant, known as STEP (Spherical Tokamak for Energy Production) will be built at the site of the former West Burton A coal power station near Retford and Gainsborough. The site was chosen by the government in 2022 as the location for the project, with the project’s delivery expected to create over 10,000 jobs ranging from construction to operations. The announcement shows the government’s firm commitment to becoming a “clean energy superpower” by turbocharging innovation in an area that’s produced conventional power for generations.

The record funding for fusion research announced this week shows the UK government’s firm commitment to clean, sustainable energy.

Optimal design could unlock the potential of bladeless wind turbines

Insights from a new study could help unlock the full potential of a developing form of smaller-scale wind power generation, researchers say.

Engineers from the University of Glasgow have used sophisticated computer simulations of bladeless wind turbines (BWTs) to identify for the first time how future generations of the technology could be built for .

The team’s paper, titled “Performance analysis and geometric optimisation of bladeless wind turbines using wake oscillator model,” is published in Renewable Energy.

Novel crystal strategy yields brighter, longer-lasting all-inorganic perovskite LEDs

Perovskite has broad application prospects in solar cells, light-emitting diodes (LEDs), and detectors due to its high luminescent efficiency and low cost. However, electrons and holes in traditional perovskite materials often struggle to effectively recombine and emit light. As a result, the strongly space-confined method is commonly employed to improve luminescence efficiency. Furthermore, how to enhance the brightness of LEDs and extend their lifespan has become a top research priority in this field.

In a study published in Nature, Prof. Xiao Zhengguo’s team from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has proposed a novel strategy based on weakly space-confined, large-grain crystals of all-inorganic perovskite to prepare with larger crystalline grains and higher temperature resistance. Researchers increased the brightness of perovskite LEDs (PeLEDs) to over 1.16 million nits and extended their lifespan to more than 180,000 hours.

Researchers developed the strategy based on the weakly space-confined technique. They first added specific compounds—hypophosphorous acid and ammonium chloride—to the perovskite material. Then, they prepared a new type of perovskite thin film with larger crystalline grains and fewer defects using a high-temperature annealing process.

Turning trash into treasure: How microwaves are revolutionizing e-waste recycling

You may not have heard of tantalum, but chances are you’re holding some right now. It’s an essential component in our cell phones and laptops, and currently, there’s no effective substitute. Even if you plan to recycle your devices after they die, the tantalum inside is likely to end up in a landfill or shipped overseas, being lost forever.

As a researcher focused on critical materials recovery, I’ve spent years digging through , not seeing it as garbage, but as an urban mine filled with valuable materials like .

Hurricanes stir deep ocean layers, bringing nutrients and low-oxygen zones to surface, study finds

With careful planning and a little luck, researchers found a surprising upside to hurricanes after a Category 4 storm disrupted their expedition off the coast of Mexico.

The team was able to sample the ocean right after the storm passed and found that the storms churn the ocean so powerfully and deeply—up to thousands of meters—that nutrient-rich, is brought to the surface.

The resulting phytoplankton blooms—visible in taken from space—are a feast for bacteria, zooplankton, small fish, and filter-feeding animals such as shellfish and baleen whales.

New bio-based hot glue made from industrial leftovers outperforms commercial adhesives

A new bio-based hot glue derived from a byproduct of the wood pulp industry beats traditional epoxy resins and commercial hot-melt glues in terms of adhesive performance.

Researchers from Beijing Forestry University developed a hot-melt adhesive derived from xylan—a complex sugar found in plant cell walls—that can be applied in a molten state and reused over 10 times without any loss of its original strength.

The synthesis strategy was reported in Nature Sustainability.
