Powering battery-free devices: Researchers develop flexible “rectennas” that convert Wi-Fi signals into electricity
For years, researchers have been developing “rectenna” that could turn Wi-Fi emissions into electrical energy so that electronic devices would be freed from the constraints of batteries and power cords. But the rectenna presented by an MIT-led team was the first example that could be flexed in any direction. Rectenna can turn any alternating current electromagnetic waves – including […]

An innovative new water filter uses bacteria to kill other bacteria
In a case of fighting fire with fire, Missouri-based researchers used a type of bacteria to produce the active material for making the membrane of a water filter. When exposed to light, the material released heat that killed harmful bacteria, thereby preventing the biological fouling of the filter. In response to the increasing strain on the […]

REALLY clean energy: Solar cells are now made from lead-free materials
Solar cells will soon become even cleaner and safer for humans without sacrificing cost and efficiency. The new perovskovite materials developed by Korean researchers do not have a single molecule of dangerous lead in them, making them safe for commercial use. Perovskovites are a class of materials with a crystalline structure similar to natural perovskite. They are […]

Finally a use for biosludge: Scientists recycle biosolids into construction-ready bricks
Recycling is all well and good. But there should be a logical limit as to which waste products should be reused and how they are going to be recycled. For example, turning biosolids into bricks sounds good on paper, but people may not be so eager about building their homes out of solidified sewage. “Biosolids” is the euphemistic term for the leftover sewage sludge of […]

Carbon emissions can now be upcycled into usable energy
South Korean researchers came up with a new clean energy generation system that could capture, use, and store carbon-based air pollutants. In addition to producing both electricity and hydrogen fuel, it also prevented the release of carbon dioxide into the atmosphere. Their hybrid sodium-carbon dioxide (Na-CO2) system used an aqueous solution to swiftly dissolve CO2 in […]

Antimony-carbon anode could pave the way for developing next-gen batteries
A newly developed antimony-carbon composite could solve the problems that beset potassium-ion battery (PIB) technology. An anode made from this material increased the amount of energy that could be stored inside the PIB unit. At the same time, it would degrade at a slower rate with every use, allowing it to last much longer. Potassium is […]

Researchers use 3D printers to make a state-of-the-art “artificial nose” that can detect toxic gases
There is almost no scent that could escape the gas sensor developed by Canadian researchers. Dubbed the “artificial nose” because it performed almost as well as the actual organ on humans, the new odor detector could analyze all kinds of scents, including dangerous gases that might cause harm to humans if inhaled. In their official statement, University […]

Japanese satellite will drop “meteors” over the city of Hiroshima
If you live in the Japanese region of Hiroshima, want a very special firework display, and have millions to splurge, you can contact a “space entertainment company” called ALE. Their newly launched satellite could create an artificial meteor shower in the skies above the city on demand. Called Sky Canvas, the Japanese microsatellite is the first of […]

Secret messages: Laser-based revolutionary technology allows researchers to send messages across noisy rooms using water vapor
Lasers can perform all kinds of roles depending on their power and frequency. Their newest application is transmitting audio signals to a person, who can hear the message clearly with no need for specialized receiver equipment. The laser-based communications technology is suitable for both mundane and critical situations. It could serve as a means of dialogue for two parties who […]

Researchers develop plant-like soft robot that can mimic tendrils
Italy now hosts the world’s very first soft robot that can move like the tendrils of a plant. Whereas other non-flying robots use mechanical limbs to scurry over surfaces, this one can curl around objects and climb surfaces like a vine. The movements of the slender robot is powered by the same hydraulic system that […]
