Strained materials make cooler superconductors

“University of Wisconsin-Madison engineers have added a new dimension to our understanding of why straining a particular group of materials, called Ruddlesden-Popper oxides, tampers with their superconducting properties. The findings, published in the journal Nature Communications, could help pave the …

Surface engineering gets the red light

“Perovskite particles could improve the performance of solar cells and light-emitting diodes via a simple process to stabilize the nanocrystal surface. A method for chemically stabilizing optical nanocrystals, without degrading their electrical properties, has been developed by scientists at KAUST …

Telegram Bot Esp8266-001(Arduino UNO or NodeMCU)

“Hello! In this tutorial i will show you how to control arduino with esp8266-001 and telegram. It opens great opportunities for Internet of Things (IoT).”

The K7TMG HF morse code temperature beacon

“This was a fun little project – and it gave me an idea for a future one. Sometimes, I find that the more complex undertakings, which require more planning, can get to the point that they “take me over” somewhat. At …

Tic Tac Toe on Arduino With AI (Minimax Algorithm)

“In this Instructable I am going to show you how to build a Tic Tac Toe game with an AI using an Arduino. You can either play against the Arduino or watch the Arduino play against itself. I am using …

Versatile Volt, Ampere, and Power Meter

“Multimeters are suitable for many purposes. But usually, they only measure one value at a time. If we deal with power measurements, we need two multimeters, one for voltage and the second for Ampere. And if we want to measure …

Yale plays quantum catch in new research

“Yale’s latest work expanding the reach of quantum information science is actually a game of quantum pitch and catch. In a new study published April 23 in the journal Nature Physics, Yale researchers “pitch” a qubit — a tiny bit …

3D Nanoprinting Facilitates Communication with Light

“At Karlsruhe Institute of Technology (KIT), researchers have developed a flexible and efficient concept to combine optical components in compact systems. They use a high-resolution 3D printing process to produce tiny beam-shaping elements directly on optical microchips or fibers and …

A powerful new source of high-energy protons

“Nearly 20 years ago, researchers conducting experiments on Lawrence Livermore National Laboratory’s (LLNL) Nova Petawatt laser system — the world’s first quadrillion-watt laser — discovered that when the system’s intense short-pulse laser beams struck a thin foil target, an …

A web configurable Xively logger, build on AVR ATmega328

“Xively (formerly Cosm and before that Pachube) is a platform devoted to simplifying the interconnection of devices and data with applications on the Internet of Things. It is an on-line database service allowing developers to connect sensor-derived data (e.g …
