CHAMPAIGN, Ill. — Millions of years of evolution have enabled some marine animals to grow complex protective shells composed of multiple layers that work together to dissipate physical stress. In a new study, engineers have found a way to mimic the behavior of this type of layered material, such as seashell nacre, by programming individual layers of synthetic material to work collaboratively under stress. The new material design is poised to enhance energy-absorbing systems such as wearable bandages and car…
A Penn State engineering student refined a century-old math problem into a simpler, more elegant form, making it easier to use and explore. Divya Tyagi’s work expands research in aerodynamics, unlocking new possibilities in wind turbine design that Hermann Glauert, a British aerodynamicist and the original author, did not consider. Tyagi, a graduate student pursuing her master’s degree in aerospace engineering, completed this work as a Penn State undergraduate for her Schreyer Honors College thesis. Her research was published in Wind Energy Science….
Scientists at Penn State have harnessed a unique property called incipient ferroelectricity to create a new type of computer memory that could revolutionize how electronic devices work, such as using much less energy and operating in extreme environments like outer space. They published their work, which focuses on multifunctional two-dimensional field-effect transistors (FETs), in Nature Communications. FETs are advanced electronic devices that use ultra-thin layers of materials to control electrical signals, offering multiple functions like switching, sensing or memory in a…
Curtin University researchers have developed a new technique to make glass water-repellent, a feature that could improve safety in vehicles, reduce cleaning costs for buildings and enhance filtration systems. The research, published in the prestigious journal Advanced Functional Materials, shows how an innovative and non-toxic process using ultrasonic sound waves can alter the surface of glass, making it either hydrophobic (water resistant) or electrically charged. Lead researcher Associate Professor Nadim Darwish, an ARC Future Fellow at Curtin’s School of Molecular…
The ancient peoples of the Philippines and of Island Southeast Asia (ISEA) may have built sophisticated boats and mastered seafaring tens of thousands of years ago—millennia before Magellan, Zheng He, and even the Polynesians. In a new paper coming out in the April 2025 issue of the Journal of Archaeological Science: Reports, Ateneo de Manila University researchers Riczar Fuentes and Alfred Pawlik challenge the widely-held contention that technological progress during the Paleolithic only emerged in Europe and Africa. They point…
Electricity generated using natural underground heat could become cost competitive with power from the grid by 2027 using enhanced geothermal systems, although care is still needed to address earthquake risks, researchers found Historically, access to geothermal energy has hinged on real estate’s famously three most important factors: location, location, and location. Because conventional geothermal power plants require hot, permeable rocks and plenty of underground fluid, use of the technology has been limited mostly to places with recent volcanism, such as Japan,…
Design to withstand hurricanes isn’t enough to protect tall buildings and facade systems against the climate crisis Houston, we have a problem. The ‘Space City’ boasts 50 buildings over 150 meters tall. These were designed to withstand hurricanes, to which Texas is prone. But on May 16th, 2024, a derecho – a wide, long-lived windstorm associated with rapidly moving showers or thunderstorms – managed to cause unexpected damage to many of the tall buildings downtown. The socio-economic impact was significant, due…
All humans need clean water to live. However, purifying water can be energy-intensive, so there is great interest in improving this process. Researchers at Tohoku University have reported a strategy using data-driven predictions coupled with precise synthesis to accelerate the development of single-atom catalysts (SACs) for more robust and efficient water purification. SACs are one of the most crucial catalysts. They play a pivotal role in enhancing efficiency in diverse applications including chemical industries, energy conversion, and environmental processes. For…
As solar energy plays an increasing role in the global power supply, ensuring accurate forecasts of photovoltaic (PV) power generation is critical for balancing energy demand and supply. A new study published in Advances in Atmospheric Sciences explores how machine learning and statistical techniques can refine these forecasts by correcting errors in weather models. Weather forecasts are a key input for PV power prediction models, yet they often contain systematic errors that impact accuracy. Researchers from the Institute of Statistics…
The research reported findings that indicate electric vehicles generally produce less non-exhaust emissions No exhaust means no emissions, right? Not quite. It is commonly known that while electric vehicles do not produce tailpipe greenhouse gas emissions while driving, they do create debris from tire and brake abrasion. However, the degree to which they do and how that compares to internal combustion engine vehicles was largely unknown until the Virginia Tech Transportation Institute’s Hesham Rakha investigated it. In an article published…
Researchers from SANKEN (The Institute of Scientific and Industrial Research), at Osaka University discover that temperature-controlled conductive networks in vanadium dioxide enhance the sensitivity of silicon device to terahertz light Osaka, Japan – High-speed electronic devices that do not use much power are useful for wireless communication. High-speed operation has traditionally been achieved by making devices smaller, but as devices become smaller, fabrication becomes increasingly difficult. Have we reached a dead end? Not yet! A research team at Osaka University…
The new method optimises the technical design with regard to classic objectives such as costs, efficiency and package space requirements and also takes greenhouse gas emissions along the entire supply chain into account The development of vehicle components is a lengthy and therefore very costly process. Researchers at Graz University of Technology (TU Graz) have developed a method that can shorten the development phase of the powertrain of battery electric vehicles by several months. A team led by Martin Hofstetter…

Long gone are the days where all our data could fit on a two-megabyte floppy disk. In today’s information-based society, the increasing volume of information being handled demands that we switch to memory options with the lowest power consumption and highest capacity possible. Magnetoresistive Random Access Memory (MRAM) is part of the next generation of storage devices expected to meet these needs. Researchers at the Advanced Institute for Materials Research (WPI-AIMR) have investigated a cobalt-manganese-iron alloy thin film that demonstrates…
In the search for new materials that can enable more efficient electronics, scientists are exploring so-called 2-D materials. These are sheets of just one atom thick, that may have all kinds of interesting electronic properties. If two sheets are placed on top of each other at specific angles, this may lead to new properties such as superconductivity. University of Groningen materials scientist Antonija Grubišić-Čabo and her colleagues studied such a ‘twisted’ material and discovered that it defied theoretical predictions. Together…
8,000 open source models for sustainable mobility. Designing new cars is expensive and time consuming. As a result, manufacturers tend to make only minor changes from one model generation to the next. With DriverAerNet++, researchers at the Technical University of Munich (TUM) and the Massachusetts Institute of Technology (MIT) have now developed the largest open-source database for aerodynamic car design. More than 8000 models representing the most common vehicle types will make it possible to create more efficient designs with…
