As technology moves forward, traditional electronics face limits. For instance, Boltzmann's law and short-channel effects pose issues for metal-oxide-semiconductor field-effect transistors (MOSFETs). But there's a new kid on the block: nanoscale air channel transistors (NACTs), which use a vacuum-li
Scientists have long known that nickel-iron catalysts are great at producing oxygen from water, especially in alkaline conditions. But how they do it so well was a mystery—until now. A recent study looked at a special catalyst, nickel-iron phosphide (NiFeP), which is super active and stable. It only
Ever heard of gold nanoclusters? They're tiny gold particles, wrapped in protective layers called ligands. These clusters are made up of smaller gold units, often triangular or tetrahedral in shape. Think of them as miniature building blocks. Scientists have been trying to figure out how these block
Ambrosia beetles, known for their penchant for farming fungus while munching on wood, are a threat to trees. These crafty critters have a unique talent: spotting stressed plants that emit ethanol. To keep them away from valuable crops, scientists have suggested using ethanol-injected trees as decoy
Scientists are always on the hunt for better ways to split water into hydrogen and oxygen. This time, they've designed special Ru-B-Cr parts within RuO₂ nanofibers to make the Ru sites more active. This overcomes the hurdles of RuO₂ catalysts, which usually aren't very good at producing hydrogen and
Scientists have been trialing a new signal-processing image analysis technology in hospitals to check out suspicious colored moles that were sent for biopsies. This technology, called Moletest, was tested on an iPadPro11 by using four different versions of its analysis software. The main goal was to
Have you ever thought about how tiny particles could help fight cancer? Meet gold-infused copper nanodots, also known as Au-doped Cu1. 92S nanodots. These tiny powerhouses have a unique ability to absorb laser light and convert it into heat, which can kill cancer cells. But that's not all! They also
Plant diseases can be a real problem for farmers. Traditional chemicals often don't work well and can harm the environment. Scientists have been looking for better ways to protect plants. One interesting solution is using tiny light-absorbing structures called photosensitizers. These little helpers
You know those creepy-crawly bugs that hang out in nests and shelters? Some of them even make palm trees their home. But a few of these bugs, known as triatomines, can be a real pain for humans. They're the ones that carry a nasty disease called Chagas. Recently, scientists found one of these bugs
You've probably heard of skin cancer, but do you know about the worst type called melanoma? It's scary stuff, because it can spread fast and can be deadly. Regularly checking your moles can help, but not many folks in Pakistan know about it. A study done at Lahore General Hospital in 2022 found that
