Copper-Gold Nanoparticles to Help Transform CO2 into Methane

Mihai Sandru — Thu, 12 Apr 2012 18:39:26 +0000

Here’s a good question for all you ecologists out there: what do we do with the carbon dioxide emissions after capturing them? As it frequently happens, MIT took up the challenge and came with a “golden”eff idea: a hybrid-copper-gold nanoparticle to transform CO2 into methane (CH4). Now why is that important – coming up with [...]

Corals Deeply Affected by Increasing Atmospheric CO2, Scientists Say

Ovidiu Sandru — Thu, 12 Apr 2012 18:36:41 +0000

The increasing CO2 concentration in air is having a profound impact on corals in the most unforeseen ways. It had been previously thought that CO2 would affect the calcium structure of the coral skeleton, but an international team of researchers proved something that’s deeper: CO2 affects the very core of the corals: their genes. “Every [...]

Copper-Graphene Alloy Cools Electronics Better, Improves Efficiency

Ovidiu Sandru — Thu, 12 Apr 2012 17:41:57 +0000

A new copper-graphene composite has been found to be the best solution so far for cooling electronic devices. It’s known that, once they pass a temperature threshold, electronics don’t behave efficiently, and that is the #1 reason for them eating more power than they should. The material developed at North Carolina State University (NCSU) is [...]

The same technique had been used before in the energy storage industry by pumping compressed air inside Earth’s crust, but the high number of [...]

Airport Grasslands Could Become Great Biofuel Source

Mihai Sandru — Fri, 06 Apr 2012 19:20:17 +0000

Airports… those large, desolating places, with lots of high-potential agricultural areas around the landing runways. Why wouldn’t they be used for something? If we are to trust a new report from the U.S. Department of Agriculture, these sites could very well grow biomass for biofuels and still not come in the way of planes or [...]

New Supermarket Scanner Scans Objects Instead of Barcodes, Saves Paper, Time and Energy

Ovidiu Sandru — Tue, 03 Apr 2012 18:59:51 +0000

Now here’s something that some may consider has nothing to do with the green purpose of our website, but I think it actually has a lot. It’s Toshiba’s new scanner that recognizes objects (fruits and vegetables, in this example) and instead of using paper-wasting barcodes, knows which is which and puts them on your supermarket [...]

New Cerium Oxide CO2-Adsorbing Material Created by Hitachi 13 Times More Efficient

Ovidiu Sandru — Tue, 03 Apr 2012 18:33:30 +0000

A new CO2-adsorbing material based on cerium oxide has been created by Hitachi. It has been designed to capture the CO2 produced by coal-fired plants and the company says it’s 13 times more efficient than old zeolitic solid adsorbents. Because old materials adsorb moisture existing in the gas, they’re not very good at separating CO2 [...]

When you look at it, you know it’s a refueling station, but not a classic one: where are the wires, the tanks and…well, everything else? That’s precisely it: the Honda Hydrogen Station at Saitama Prefectural Office in Japan is not your average gas station. In fact, it’s not even a gas station at all: it’s [...]

Chinese Scientists Find Alternative to Lead-Containing Mainstream Piezoelectric Material

Ovidiu Sandru — Mon, 02 Apr 2012 17:57:43 +0000

You probably learned in high school what the piezoelectric effect is: a phenomenon where an electromotive force is generated by applying mechanical stress to a material. So far, piezoelectric devices used a material called lead zirconate titanate (PZT). However, PZT is expensive and contains lead, which is bad for the environment. Progress does happen, though, [...]
