Can pure water store electrical energy? A research team led by Dr. Vasily Artemov within the Cluster of Excellence "BlueMatβWater-Driven Materials" at Hamburg University of Technology has now shown that it can. By confining water within nanometer-sized channels in clay minerals, the researchers created a supercapacitor capable of efficiently storing and transporting electrical charge.
The critical minerals that power lithium-ion batteries are in high demand and short supply, especially for the U.S., which must rely on importing resources such as nickel and cobalt to manufacture the technology.
Consumers often assume that choosing more environmentally friendly products helps reduce environmental harm. New research suggests that reality may be more complicated. The findings are published in the journal Marketing Science.
Every day, billions of people trust computer chips to protect their most sensitive information, ranging from banking passwords to national security secrets. But what if those chips were secretly compromised before they even left the factory?
As concerns grow over global fuel supplies and the cost of flying, new research from the University of Adelaide shows the relationship between jet fuel prices and airfares is not as simple as passengers might think. The study found that different types of jet fuel price shocks have very different effects on Australian domestic airfares, with some shocks leading to higher ticket prices, some having little effect, and others pushing fares in different directions across fare classes.
Microbial fuel cells (MFCs), which use microorganisms to generate electricity from organic waste, are emerging as a tool in the transition to cleaner energy systems and for the treatment of wastewater, according to a review of recent research published in the International Journal of Environment and Waste Management.
Randomness forms a crucial backbone of modern society, where every encryption key, secure transaction and digital signature depends on random numbers that no adversary can predict. But every random number generator ever deployed, classical or quantum, has asked its users to take the hardware's honesty on faith.
The EU on Tuesday rejected Apple's blame for the delayed rollout of its AI-enhanced voice assistant, saying it was up to the U.S. giant to make products that follow the rules.
European Union regulators on Tuesday ordered Meta Platforms to restore access to WhatsApp for rival AI chatbot makers until an antitrust investigation is complete.
Humanoid robots struggling with tasks like grasping a cup have a new teacherβa person wearing an ultrasound wristband that captures the movement of muscles, tendons and ligaments beneath the skin.
Transistors, small devices that can amplify or switch electrical signals, are central components of all modern computer chips and digital devices. There are two main types of transistors, known as n-type and p-type transistors.
From personal health portals to AI assistants that draft emails, the digital age has simplified endless everyday tasks. But for many older New Zealanders, the rapid march of technology has helped build a wall rather than open doors. Navigating online forms, changing apps, disappearing face-to-face services, and the constant threat of scams can be daunting.
In a recently published article in the Harvard Business Review, UConn management professor Timothy B. Folta and two European colleagues discovered that in hypercompetitive business markets, a less-resourced but more spirited and focused company is likely to fight a rival to the bitter end.
Although self-driving cars and sophisticated robots use advanced cameras, computer algorithms and artificial intelligence to perceive their surroundings, these artificial eyes struggle to remain reliable in mixed lighting conditions. A team of researchers, co-led by an engineer from Penn State, has proposed a solution that mimics the mechanics of the human eye to adapt from bright to dark light in seconds.
OpenAI, maker of ChatGPT, on Monday took the first step toward going public, one week after rival Anthropic announced its own filing, as both companies look to raise the massive sums needed to expand.
