Tech Xplore / Confined crystallization strategy improves spray-coated perovskite device performance
Metal halide perovskites are promising for next-generation high-efficiency photovoltaic and optoelectronic devices due to excellent tunable properties and solution processability. Recent fabrication techniques (such as spin ...
Tech Xplore / Electrochemical tuning of Ni-rich cathodes curbs c-collapse, enhancing lithium-ion battery durability
Lithium-ion batteries (LiBs) remain the most widely used rechargeable batteries worldwide, due to their light weight, high energy densities and their short charging times. Energy engineers have been trying to identify new ...
Tech Xplore / How cement 'breathes in' and stores millions of tons of CO₂ a year
The world's most common construction material has a secret. Cement, the "glue" that holds concrete together, gradually "breathes in" and stores millions of tons of carbon dioxide (CO2) from the air over the lifetimes of buildings ...
Tech Xplore / How AI helps solve problems it doesn't even understand
Researchers at TU Wien have discovered an unexpected connection between two very different areas of artificial intelligence: Large Language Models (LLMs) can help solve logical problems—without actually "understanding" ...
Tech Xplore / Researchers reveal bias in a widely used measure of algorithm performance
When scientists test algorithms that sort or classify data, they often turn to a trusted tool called Normalized Mutual Information (or NMI) to measure how well an algorithm's output matches reality. But according to new research, ...
Tech Xplore / Harry Potter-style 'moving invisibility cloak' technology developed
What do Harry Potter's invisibility cloak and stealth fighter jets that evade radar have in common? They both make objects invisible despite their physical presence. Building upon this concept, a research team has taken it ...
Tech Xplore / Engineers develop real-time membrane imaging for sustainable water filtration
CU Boulder researchers have introduced a solution to improving the performance of large-scale desalination plants: stimulated Raman scattering (SRS).
Tech Xplore / New 3D benchmark leaves AI in knots
Today's artificial intelligence models can't even tie their own shoes.
Tech Xplore / 'Robot, make me a chair': AI-driven system designs, builds multicomponent objects from user prompts
Computer-aided design (CAD) systems are tried-and-true tools used to design many of the physical objects we use each day. But CAD software requires extensive expertise to master, and many tools incorporate such a high level ...
Tech Xplore / Transparency in AI companies falls to new low
A new analysis finds that AI companies now average just 40 out of 100 on transparency, marking a significant decline from last year.
Tech Xplore / Assumptions about battery failure challenged: Single-crystal materials require different approach than expected
New research from Argonne National Laboratory and the UChicago Pritzker School of Molecular Engineering (UChicago PME) has solved a major battery mystery that has led to capacity degradation, shortened lifespan and, in some ...
Tech Xplore / Detecting distant vehicles for safer roads: A new camera-based technique sees farther
Road accidents often stem from failing to notice vehicles. A study published in the journal IEEE Open Journal of Intelligent Transportation Systems introduces a method for detecting distant vehicles with over twice the accuracy ...
