While moving robots find their way in their environment by GPS, researchers have now constructed one that navigates like a desert ant. Desert ants use the polarized pattern of skylight and combine this with an estimation of the distance traveled based on how many steps they took and to the rate at which the ground moves across the eye. The newly developed robot uses these principles successfully, as indicated by the mean homing error of only 0.67%. Thus, it seems possible to use the…

New hydrogel material works like human muscle

A new material made from a double-network of hydrogels has the ability to increase its strength in response to mechanical stress, similar to the human muscles. This ability allows the material to repair the damage induced by tensile forces. The material contains two intertwined networks of polymer strands, with one network rigid and the other one flexible. The rigid component breaks down when mechanical stress is applied, but this triggers a local polymerization process that creates new…

Thermoelectric paper produced by a sustainable and environmentally friendly process, Bacteria help scientists to grow thermoelectric paper. It could generate electricity from residual heat

Thermoelectric paper produced through sustainable and environmentally friendly process

Researchers announced the development of a new method to produce thermoelectric paper that is both sustainable and environmentally friendly. Thermoelectric paper is a material made of cellulose, containing small amounts of conductive nanomaterials that enable it to convert heat into electricity. The scientists used bacteria to produce the nanocellulose fibers that end up forming the device. The new material has high thermal stability (it can reach up to 250 Celsius degrees) and it doesn’t…

We all have played with bird feathers and watched with amazement how the feather unzips and zips effortlessly and pulls itself back together. In a major scientific discovery, researchers for the first time in two decades looked at the detailed structure of the feather and found that regardless of the species, the barbules (structures that connect feather barbs) are spaced 8-16 micrometre apart. This indicates that this spacing is important in flight since it is conserved across different…

Researchers have developed Fluoride-based batteries which could potentially last eight times longer effectively reducing the number of times you need to charge your devices. They have developed the first rechargeable fluoride batteries using liquid components that work at room temperatures. Batteries drive electric currents by shuttling ions between positive and negative electrodes. While, the current lithium-based batteries use positive lithium ions for this, the new fluoride-based…

A new technology with nanowires can potentially mimic the human brain Brain Science, Science News, B Rain, New Technology

Nanowires used to create artificial synapses

In a major breakthrough, scientists have produced a memristive element from nanowire which functions similar to a neuron. This element can both process and save information and also receive several signals in parallel. These elements are made of a single zinc oxide nanowire, which is approximately a thousand times thinner than a human hair. This nanowire is attached to silver and platinum metals which function as electrodes that can release ions at an appropriate current. This paves the way…

Scientists developed better electrochemical systems composed of organic materials and bacteria

Account Suspended

Electrochemical systems containing bacteria have been described before, but in practice, they are difficult to use because of their large size. To improve them, miniaturization is necessary. Now, scientists developed a new technique to create fine organic electrodes of up to 80 micrometers thick. The researchers used an electrically conducting polymer (PEDOT:PSS) and the electroactive bacterium Shewanella oneidensis to obtain the new electrodes. When the resulting system is used as the anode…

To remove mercury from contaminated water, mercury ions (light purple) are attracted to an electrode's surface where they get reduced to metallic mercury (dark purple) and form an alloy with platinum atoms (grey) Chalmers University, New Technology, Mercury, How To Remove, Cleaning, Water, Light Purple, Dark Purple, Plastic Recycling

New technique to remove toxic mercury from contaminated water

Researchers have established a new technique to remove the highly toxic mercury from contaminated water. The new method is based on electrochemistry. Mercury ions are attracted to a metal plate, an electrode of platinum, get reduced to metallic mercury and together, mercury and platinum form a stable alloy. Each platinum atom can bond four mercury atoms, and do not bond with other ions in the water. Mercury can then be safely removed from the electrode, which can thus be reused. Read the…

MIT engineers fly first-ever plane with no moving parts in propulsion system – MIT Electric Aircraft Initiative

Account Suspended

Every know aircraft today has some moving parts such as propellers and fans, however, researchers from MIT just announced building the first plane with no moving parts. And it flies, too! The new design doesn’t use fossil fuel. Instead, it is powered by ions generated by electrically charged electrodes and lithium-polymer batteries. These parts produce “ionic wind” that enable the plane to lift off. Moreover, it is completely silent while flying. The team flew the plane over a distance of 60…

Melting gold normally requires temperatures upwards of C F), but physics is never quite that simple. A team of researchers has now found a way to melt gold at room temperature using an electric field and an electron microscope.

Melting gold at room temperature

Researchers have, for the first time, managed to melt gold at room temperature. There’s no need to rush and put your jewelry in the fridge! An intense electrical field is needed for the melting to occur. The scientists placed a small piece of gold in an electron microscope and gradually exposed it to an increasingly stronger electrical field. The electric field excited the gold atoms which lost their ordered structure and released almost all their connections to each other. In other words…

Use of a polymer increases lithium battery life

Lithium batteries that run longer and charge faster can become a reality soon. Scientists have developed the next generation of such metal batteries by using a special polymer on the interface of the lithium metal. This material acts as a porous sponge that not only promotes ion transfer, but also stops deterioration of lithium, even when batteries are being charged fast. Scientists estimate that the life of lithium batteries can double this way, meaning less recharging of your mobile phone…
