Colour-changing sensor raises a pink flag to hydrogen leaks

Posted by in categories: electronics, energy

A simple colour change could indicate the presence of potentially hazardous hydrogen gas thanks to a new sensor developed by researchers in Germany. The micron-scale device, which uses so-called “supraparticles” that turn from purple to pink in the presence of hydrogen, could help prevent explosions by making it easier to detect and localize leaks at fuel stations, generators and pipelines.

The Real Minesweepers Are Changing Lives and Saving Limbs

Posted by in categories: electronics, materials

And it could mean signs of the war will remain for a long time. Reports are in that Russian forces are laying “smart” landmines in Ukraine that are only able to target soldiers. Called the POM-3 “Medallion” landmine, these anti-personal weapons are activated, allegedly, specialist seismic target sensors.


Once the conflict ends, it is important to begin the process of “demining.” The goal is to clear the land of any explosive devices that pose a risk to the population. Currently, there are an estimated 110 million landmines scattered across dozens of war-torn countries, and approximately 26,000 people per year (or roughly 70 people per day) die due to these devices.

Many die while trying to collect parts of the metal mines for scrap, or by accidentally triggering the mines. Here’s a look at a few different technologies, both old and new, that are working to clear affected areas of these destructive weapons.

This portable lantern hosts a customizable OLED screen that transforms into a projection screen

Posted by in categories: biotech/medical, electronics

Rén is a customizable lantern with an integrated OLED screen for users to project whatever moving images or videos they’d like.

Over the past few years, we’ve learned to prioritize what is most important to us. From going to the virtual family reunion to getting creative in the arts, we’re keeping the stuff that matters most to us extra close. Since the pandemic has transformed many of those experiences into digital ones, designers shave been getting creative in making them as large as real life, and sometimes even larger.

St Louis’s new fleet of 18 New Flyer electric buses powered by ABB chargers

Posted by in categories: electronics, sustainability

The city of St. Louis, Missouri fleet plans to deploy 18 electric buses on the city’s busiest routes. Charging infrastructure for the 60-seat New Flyer buses will be provided by Swiss/Swedish electronics giant ABB.

St. Louis transit agency Metro Transit says it expects the e-buses to reduce carbon emissions by 100 to 160 tons per year, and to deliver up to $125,000 in maintenance savings and $400,000 in fuel savings over their 12-year lifespan.

ABB will provide 23 Buy America-compliant chargers, with a total of over 4.35 MW of charging capacity. ABB’s sequential charging system consists of 20 plug-in depot chargers, each with 150 kW of power, and three additional pantograph chargers. St. Louis’s buses can be fully charged in one hour. ABB says its fast-charging system easily integrates with existing transit schedules, so cities can switch to zero-emission buses without disrupting existing routes.

Team at Borexino shows it is possible to have directional and energy sensitivity when studying solar neutrinos

Posted by in categories: electronics, particle physics

A group of researchers working with data from the Borexino detector at the Laboratori Nazionali del Gran Sasso in Italy, has shown that it is possible to measure solar neutrinos with both directional and energy sensitivity. Two teams within the group have written papers describing the work by the group—one of them has published their work in Physical Review D, the other in Physical Review Letters.

The Borexino detector was first proposed back in 1986 and its structure was completed in 2004. In May of 2007, it began providing researchers with data. Its purpose has been to measure neutrino fluxes in proton-proton chains. The detector, which is currently being dismantled, was made using 280 metric tons of radio-pure liquid scintillator which was shielded by a layer of water. Detections were made as scattered off electrons in the scintillator—the light that was emitted was picked up by sensors lining the tank.

For most of its existence, data from the Borexino detector was an excellent source of high-resolution sensitivity data down to low energy thresholds, but it offered little in the way of directional trajectories. In this new effort, the researchers found a way to use the data from the detector with data from another detector to provide trajectory information.
