3D Printed Optics with Nano Meter Scale Surface Roughness

“Stanford researchers successfully manufactured high quality optical components using commercially available 3D printing materials. Researchers print optical surface (mirrors, arrays, lens molds), and coat it with a gel. Following curing, the optically smooth surface can be vacuum coated with Al …

A colossal breakthrough for topological spintronics

“BiSb expands the potential of topological insulators for ultra-low-power electronic devices Scientists have developed the world’s best-performing pure spin current source1 made of bismuth–antimony (BiSb) alloys, which they report as the best candidate for the first industrial application …

A fault-tolerant system for stopping ‘leaks’ in quantum computers

“Yale researchers have designed a new system to keep tomorrow’s quantum computers from “leaking.” Large-scale quantum computers are still years away, but it is well known that they will need error correction. All of the components in a quantum …

Advance Could Yield Safer, Longer-Range Electric Car Batteries

“A team of researchers from the University of Maryland, the Army Research Laboratory and Argonne National Laboratory (U.S. Department of Energy) has published findings on a new advanced battery technology that among its many possible applications has the potential …

Arduino Based Oil Dispenser

“we all love food isn’t that right? of course yes, everyone has tried cooking once in their life, and already knows the struggle to get exact amount of oil for the perfect recipe, so here is a project which …

Arduino Tension Scale With 40 Kg Luggage Load Cell and HX711 Amplifier

“This Instructable describes how to make a tension scale using readily available off the shelf parts. Materials needed: 1. Arduino - this design uses a standard Arduino Uno, other Arduino versions or clones should work also 2. HX711 on breakout board …

Army’s new 3-D printed shape-shifting soft robots crawl, jump, grab

“New 3-D printed robotic structures can squeeze in tight spaces like a crack in the wall of a cave, jump over trip wire or crawl under a vehicle - all complex Army-relevant functions impossible for humans to perform safely. Investigators at …

Artificial intelligence can predict your personality… simply by tracking your eyes

“It’s often been said that the eyes are the window to the soul, revealing what we think and how we feel. Now, new research reveals that your eyes may also be an indicator of your personality type, simply by …

Automatic Humidifier Control Using ESP328266

“Today, I decided to show a project that I actually made for use in my own home. I have an air humidifier, which often leaves the room too dry. And sometimes, it leaves water on the floor around it. So …

Better way found to determine the integrity of metals

“Researchers at the University of Waterloo have found a better way to identify atomic structures, an essential step in improving materials selection in the aviation, construction and automotive industries. The findings of the study could result in greater confidence when …
