Bricks that store energy
Scientists have developed a way to store energy in red bricks, which are commonly used in building construction. Researchers at Washington University in St. Louis, Missouri, have devised a method for transforming common building materials into "smart bricks" that store energy like a battery.
Although the study is still in its early stages, the scientists believe that walls composed of these bricks “may store a significant amount of energy” and “can be recharged hundreds of thousands of times within an hour.”A red brick gadget created by scientists at Washington University in St. Louis illuminates a green light-emitting diode D’Arcy laboratory/ Washington University in St. LouisThe researchers devised a technique for converting red bricks into a form of energy storage device known as a supercapacitor.
This entailed applying a conducting coating known as Pedot on brick samples, which subsequently seeped through the porous structure of the burnt bricks, transforming them into “energy-storing electrodes.”According to the researchers, iron oxide, which is the red pigment in the bricks, aided in the process.
Smart watches powered by sweat
Engineers at the University of Glasgow have created a new form of flexible super capacitor that stores energy by using sweat instead of the electrolytes used in traditional batteries.
It may be completely charged with as little as 20 micro litres of fluid and is strong enough to withstand 4,000 cycles of the various flexes and bends that it may face in usage. The gadget functions by covering polyester cellulose fabric in a thin layer of a polymer that serves as the supercapacitor’s electrode.

As the fabric absorbs the perspiration of its wearer, the positive and negative ions in the sweat contact with the surface of the polymer, causing an electrochemical process that creates energy.” Conventional batteries are cheaper and more available than ever before, but they are frequently manufactured using unsustainable materials that are hazardous to the environment,” Professor Ravinder Dahiya of the James Watt School of Engineering at the University of Glasgow agrees.
"As a result, they are difficult to dispose of properly and may be dangerous in wearable devices, where a damaged battery may spill poisonous substances on the skin." something new for the first time we're able to demonstrate that human sweat provides a real opportunity to totally remove those harmful substances while simultaneously delivering excellent charging and discharging performance.
‘Living concrete’ that heals itself
Bacteria developing and mineralizing in a sand-hydrogel framework CU Boulder/PAUsing sand, gel, and bacteria, scientists created what they term alive concrete. According to the researchers, this construction material has structural load-bearing capabilities, is self-healing, and is more ecologically friendly than concrete, which is the second most used resource on Earth after water. The University of Colorado Boulder team believes their research paves the path for future building constructions that can “repair their own fractures, suck up harmful chemicals from the air, or even light on command.”
Robots that are alive
Tiny hybrid robots generated from frog embryo stem cells might one day be used to swim around human bodies to particular places in need of treatment or to collect microplastic within the oceans.” These are innovative living robots,” said Joshua Bongard, a computer scientist and robotics expert at the University of Vermont who co-created the millimeter-wide xenobiotics. They are neither a typical robot nor a known animal species.”
A living, programmable organism is a new type of object.”
Everyone can use the internet.
We can’t seem to live without it (how else would you read sciencefocus.com? ), yet only around half of the world’s population is online. There are several reasons for this, including economic and societal factors, but for some, the internet is just inaccessible due to a lack of connectivity. Google is gradually attempting to fix the problem by employing helium balloons to beam internet connectivity to remote places, but Facebook has planned use of drones has been abandoned, allowing firms like Hiber to steal a march. They’ve chosen a different route, launching their own network of shoebox-sized microsatellites into low Earth orbit, which wakes up a modem linked into your computer or gadget as it passes overhead and transfers your data.
Their satellites orbit the Earth 16 times per day and are already utilized by organizations such as The British Antarctic Survey to deliver an internet connection to the most remote parts of our world.
The power of coffee
Every year, the coffee business in London generates almost 200,000 tons of garbage; what do we do with it? Arthur Kay’s great concept is to utilize his firm, bio-bean, to convert 85 percent of coffee waste into biofuels that can be used to heat buildings and power transportation. The firm, which is already the world’s largest recycler of coffee waste, gathers coffee grounds from huge chains and restaurants as well as smaller coffee shops and brings them to its Cambridge shire processing plant.
The grounds are dried and processed there before being utilized to make goods like pellets or logs for biofuel, bioplastics, or flavorings.
Forest fires will be drowned out by the music.
Drones those direct loud noises at the trees below might one day be used to combat forest fires. Because sound is made up of pressure waves, it may be used to disturb the air around a fire, thereby cutting off the fuel’s source of oxygen. The fire simply goes out at the correct frequency, as researchers at George Mason University in Virginia recently proved with their sonic extinguisher. Bass frequencies appear to be the most effective.
