“Perovskite materials are low-cost, solution-processable semiconductors that can absorb and convert solar energy with extraordinarily high efficiencies, making them promising material for use in applications such as photovoltaic solar cells – if the material can be made stable and efficient. In …
“It’s quite rare these days to find someone carrying a pocket calculator but school students who are don’t allowed to carry phones may use it, or why don’t they create their own pocket calculator. In this Instructable …
“This is PlottyBot, a pen plotter you can build. It’s based on a Raspberry Pi Zero W which means it’s loaded with software to make it easy to use. It also comes with novel features.”
“Researchers discover a new hydrogen compound crystal structure as a likely candidate for achieving superconductivity at high temperatures The low temperatures required to maintain superconductivity have led to the development of hydrogen-containing compounds (metal hydrides) that can achieve superconductivity at …
“Rare earth elements are hard to get and hard to recycle, but a flash of intuition led Rice University scientists toward a possible solution. The Rice lab of chemist James Tour reports it has successfully extracted valuable rare earth elements …
“In this post I want to talk about the new Raspberry Pi 4 (RPI4) and one of its new features: Multiple (up to 6) accessible SPIs! While the older RPIs all had SPI0, SPI1 and SPI2, only SPI0 and SPI1 …
“Relay Shield can be used to be control devices wirelessly with your smartphone from anywhere. Every household has electronic devices which are a major part of our everyday life like dishwashers, washing machines, boilers (water heaters), kettles. All of the …
“Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing. Whether for use in cybersecurity, gaming or scientific simulation, the world needs true random numbers, but generating …
“Researchers have developed a 46-inch woven display with smart sensors, energy harvesting and storage integrated directly into the fabric. An international team of scientists have produced a fully woven smart textile display that integrates active electronic, sensing, energy and photonic …
“Thermal span in a layered compound promises applications in next-generation electrical switches and nonvolatile memory. When temperature changes, many materials undergo a phase transition, such as liquid water to ice, or a metal to a superconductor. Sometimes, a so-called hysteresis …
