When a hurricane strikes, the most vulnerable are not always able to get out in time. UT Austin scientists are using supercomputers at the Texas Advanced Computing (TACC) to study how shared autonomous vehicles (SAVs) can get people who do not have their own car into shelters out of harm's way.

Proper power grounding systems are necessary for maintaining the safety and reliability of critical electrical subsystem infrastructure, such as substations. Power grounding systems provide a low-resistance path for electrical fault currents to flow into the earth, preventing electrical shocks, fires, and damage to vital equipment. Investigation of soil resistivity is crucial for designing power grounding systems.

A research team led by Prof. Ye Hong from the University of Science and Technology of China has developed an alumina ceramic bionic wick with finger-like pores inspired by the stomatal array of natural leaves. Their research is published in Langmuir.

As the demand for energy storage diversifies, the limitations of lithium supplies drive a shift toward alternative technologies. Sodium, potassium, magnesium, and zinc-ion batteries emerge as promising contenders, yet face challenges in capacity, charge-discharge rate, and stability. This backdrop underscores the need for innovative approaches like carrier pre-intercalation to elevate the electrochemical performance of electrode materials.

New research published in Business Strategy and the Environment based on information from G7 countries demonstrates that green finance—loans, investments, and incentives that support environmentally-friendly projects and activities—can reduce carbon dioxide emissions. Also, data indicate that investments in green projects are profitable.

Researchers at the University of Waterloo have designed an energy-efficient device that produces drinking water from seawater using an evaporation process driven largely by the sun.

Researchers at Rolls-Royce University Technology Centre (UTC) in Manufacturing and On-Wing Technology at the University of Nottingham have developed ultra-thin soft robots, designed for exploring narrow spaces in challenging built environments. The research is published in the journal Nature Communications.

Researchers from the University of Hertfordshire have developed a new algorithm that will allow robots to function more intuitively—that is, make decisions using their environment for guidance.

Chronic low-frequency noise from vehicles, appliances, and industries takes a toll on mental health, causing stress and anxiety. Traditional acoustic silencers require bulky designs to achieve effective noise reduction at low frequencies.

It's no secret Australia has abundant and cheap renewable energy, especially wind and solar power. But yes, there are times when the sun doesn't shine and the wind doesn't blow. We need energy storage to get us through those still nights and dreary days.

憑藉其豐富的再生能源（太陽能和風能）以及綠氫生產計劃，南非有望成為全球能源轉型的主要參與者。

Humans generate a lot of plastic waste—more than 400 million metric tons a year.

Researchers at the Indian Institute of Science (IISc) have developed a brain-inspired analog computing platform capable of storing and processing data in an astonishing 16,500 conductance states within a molecular film. Published today in the journal Nature, this breakthrough represents a huge step forward over traditional digital computers in which data storage and processing are limited to just two states.

On a recent morning, a self-driving car navigated a curvy Chattanooga street by "listening" to the road's reflective lane markers. Oak Ridge National Laboratory and Western Michigan University researchers demonstrated the technology to officials with the City of Chattanooga and Hamilton County, Tennessee.

A joint research team from the School of Energy and Chemical Engineering and the Department of Chemistry at UNIST has addressed critical challenges in perovskite solar cell (PSC) production, significantly enhancing both their efficiency and stability, which is expected to further bolster their commercialization potential.

A study published in Engineering has shed light on the pivotal role of urban underground space (UUS) development in achieving carbon neutrality, with significant implications for sustainable urban development in China and beyond.

Solar energy is a promising way of reducing our dependence on fossil-fuel-based energy resources to opt for cleaner energy forms. Over the years, solar cells that can harness this renewable energy have undergone significant progress.

One of the drawbacks of fitness trackers and other wearable devices is that their batteries eventually run out of juice. But what if in the future, wearable technology could use body heat to power itself?

When cars, planes, ships or computers are built from a material that functions as both a battery and a load-bearing structure, the weight and energy consumption are radically reduced. A research group at Chalmers University of Technology in Sweden is now presenting a world-leading advance in so-called massless energy storage—a structural battery that could halve the weight of a laptop, make the mobile phone as thin as a credit card or increase the driving range of an electric car by up to 70% on a single charge.

Organic solar cells (OSCs)—promising alternatives to traditional inorganic solar cells—have many features that make them key players in a greener future. One of these features is tunable chemistry, which allows scientists to precisely adjust or modify the properties of chemical systems to achieve desired outcomes. Now, researchers from Japan have tuned them to increase power conversion efficiency.
