There is an urgent need to address climate change, making the development of sustainable energy alternatives more important than ever. While proton-exchange membrane fuel cells (PEMFCs) have shown great promise for energy production, particularly in the transportation industry, there is a long-standing problem with their durability and cost.
A Western research team has addressed the issue with a new cobalt-modified nanomaterial making PEMFCs more robust, readily sourced and environmentally sustainable demonstrating just a two percent loss in efficiency rate following 20,000 cycles in a durability test.
The new nanomaterial is used to enhance oxygen reduction reaction (ORR), the process that forms water in the fuel cell allowing a higher current for more efficient power generation. The cobalt-modified nanomaterial also reduces the reliance on platinum to construct these fuel cells. A costly precious metal, and mined primarily in South Africa, only a few hundred tons of platinum are produced annually.
Ultracapacitors have significant advantages over batteries, after all, they are much lighter, faster to charge, safer, and non-toxic. However, there are some areas where batteries wipe the floor with them, at least for now.
With recent acquisitions of ultracapacitor manufacturers by the likes of Tesla, ultracapacitors could be on the verge of ousting batteries as the go-to power source for electric cars.
Innovation thrives when we pause to observe, question, and reimagine the world around us, turning challenges into opportunities for progress. Nature, in particular, serves as a rich source of inspiration. By observing it, studying its daily challenges, and contemplating its processes, we can discover valuable insights that inspire innovative solutions.
One of these current challenges is the production of concrete, an ancient and extremely popular material that is now accountable for a significant portion of global CO₂ emissions, due to the energy-intensive process of cement production and the chemical reactions involved. It is estimated to be responsible for approximately 8% of the world’s… More.

Artificial photosynthesis, the next-generation technology, has now come this far! It is a technology that mimics plant photosynthesis to produce energy from resources found on earth such as sunlight and carbon dioxide. This is a promising new solution to energy and environmental problems as it can efficiently produce hydrogen and other substances. Japan was one of the first countries to recognize this technology and had launched a national project that involved the collaboration among industry, academia, and government. In 2021, they successfully produced large amounts of hydrogen, taking the world by surprise. Also in this episode, take a look at a system that can power homes using carbon dioxide. Find out the latest in artificial photosynthesis with reporter Michelle YAMAMOTO.
Researchers at Tokyo Tech have demonstrated that in-cell engineering is an effective method for creating functional protein crystals with promising catalytic properties. By harnessing genetically altered bacteria as a green synthesis platform, the researchers produced hybrid solid catalysts for artificial photosynthesis.
Photosynthesis is how plants and some microorganisms use sunlight to synthesize carbohydrates from carbon dioxide and water.
Core inflation remains elevated in advanced economies, with economists calling for tighter monetary policies in order to improve price and financial stability for sustained economic growth. With inflation only slowly moving towards sustainable targets, investors can leverage insights into teen spending patterns, behaviors, and advancements in technology to identify broader economic and market trends.
In a recent Piper Sandler Taking Stock With Teens survey that analyzed discretionary spending patterns, fashion trends, technology, and brand and media preferences, inflation was determined to be the number two social concern among teens, pointing to initial signs of a slowdown in teen spending.
“Inflation reached its highest mindshare in terms of political and social issues, right behind the environment,” said Edward Yruma, senior research analyst.

Global warming has severely impacted the supply of fresh water in many parts of the world. Coastal communities have resorted to salination plants while those in the far interior have no option but to extract water from the air. Most of these techniques are energy-intensive or only work under certain conditions. Now, a new technology developed by researchers at ETH Zurich can help humanity access fresh water 24 hours a day and without spending any energy.
The technology might not look so sophisticated at first, and one might just say that it’s just another regular glass pane. But only the researchers who developed it will tell you that this glass pane is coated with special polymers and silver layers that give the glass properties to reflect solar radiation and also emit heat directly into outer space.
New research conducted by the not-for-profit organisation, Material Focus, has found that half a billion small, cheap electrical everyday items, such as headphones or handheld fans, found their way into landfill in the UK last year.
Consumers discard or possess disused electronic goods containing raw materials critical for the green energy transition and worth almost $10 billion every year, the United Nations said on Thursday.
Toys, cables, electronic cigarettes, tools, electric toothbrushes, shavers, headphones and other domestic gadgets contain metals like lithium, gold, silver and copper.
Demand is expected to soar for these materials due to their crucial role in rapidly growing green industries such as electric vehicle battery production.
