Tech Xplore / New framework designs scalable 3D transistors based on 2D semiconductors
Conventional electronics based on silicon are approaching their limits in terms of performance and scalability. In recent years, engineers have thus been trying to introduce alternative designs that could help reduce the ...
Tech Xplore / Researchers find the key to AI's learning power—an inbuilt, special kind of Occam's razor
A study from Oxford University has uncovered why the deep neural networks (DNNs) that power modern artificial intelligence are so effective at learning from data.
Tech Xplore / Silicon photonics advance paves the way for cost-effective, high-performance optical devices
Imec, a research and innovation hub in nanoelectronics and digital technologies, has announced a significant milestone in silicon photonics with the successful demonstration of electrically driven GaAs-based multi-quantum-well ...
Tech Xplore / Next-generation wearables: Compact cooling pump drops temperatures by 16°F
UCLA materials scientists have developed a compact cooling technology that can pump away heat continuously using layers of flexing thin films. The design is based on the electrocaloric effect, in which an electric field causes ...
Tech Xplore / Green hydrogen: Study shows big gaps between ambition and global implementation
In recent years, more than 60 countries have developed strategies to stimulate the market ramp-up of hydrogen, particularly in the industrial sector. However, in 2023, less than 10% of the originally announced green hydrogen ...
Tech Xplore / LlamaV-o1: Curriculum learning–based LLM shows benefits of step-by-step reasoning in AI systems
A team of AI researchers at Mohamed bin Zayed University of AI, in Abu Dhabi, working with a colleague from the University of Central Florida, has developed a curriculum learning–based LLM, called LlamaV-o1, that its makers ...
Tech Xplore / Self-adjusting shading system mimics pine cones for energy-autonomous weather response
Using pine cones as a model, researchers at the universities of Stuttgart and Freiburg have developed a new, energy-autonomous facade system that adapts passively to the weather. The journal Nature Communications has published ...
Tech Xplore / Nature-inspired design uses elastic pillars to eject freezing droplets, preventing ice buildup
Water droplets under freezing conditions do not spontaneously detach from surfaces as they do at room temperature due to stronger droplet-surface interaction and lack of an energy transformation pathway. Since accumulated ...
Tech Xplore / New electrical pulse method enhances carbon fiber recycling efficiency
The world is hurtling rapidly towards a developed future, and carbon fiber-reinforced polymers (CFRPs) play a key role in enabling technological and industrial progress. These composite materials are lightweight and highly ...
Tech Xplore / Amsterdam experiment shows how households can cut energy costs by about 50%
Many people around the globe are living in energy poverty, meaning they spend at least 8% of their annual household income on energy. Addressing this problem is not simple, but an experiment by MIT researchers shows that ...
Tech Xplore / Losing to lithium: Research shows sodium-ion batteries need breakthroughs to compete
Legions of battery engineers and their supporters have sought for years to build batteries cheaper than the dominant lithium-ion technology, hoping to capture some of lithium-ion's $50 billion-a-year and growing market. The ...
Tech Xplore / New training technique opens the door to neural networks that require much less energy
AI applications like ChatGPT are based on artificial neural networks that, in many respects, imitate the nerve cells in our brains. They are trained with vast quantities of data on high-performance computers, gobbling up ...
