Batteries forever .. Will the Russian invention lead to dispensing with batteries
Russian specialists in physics and radio equipment presented their new invention in the field of electronics.
In the future, the project will be applied in all major industries. The developers believe that the power sources created using their technology will replace conventional batteries in the future.
New technology features
This is a technique for improving the electronic components of microcircuits. A technology to create more durable hydrogen batteries that are integrated into printed circuit boards and the electronic parts themselves. This technology involves creating a silicone film directly on the board, which allows several times to improve its functional properties.
For this purpose, the porous silicon structure is also covered with a layer of graphene.
This material helps reduce surface resistance and increases the resistance of the board to alkaline liquids and oxidizing agents. Older PCBs had a layer of expensive platinum instead of graphene.
The uniqueness of this technique lies in the fact that the chemical effect of alcohol vapors is used to deposit the graphene layer on porous silicon.
During the reaction, a sudden decrease in pressure occurs inside the working chamber, due to which graphene is deposited with the greatest possible density on the silicon membrane, completely covering the pores.
As a result of the chemical interaction of the elements, a unique nanocomposite material is created, from which printed circuit boards for microelectronics can be made. These products will have high electrical conductivity and increased resistance to destruction and overheating.
No batteries needed
There is no need to produce electrodes for today's efficient micro-fuel cells. Electricity sources of this type will be able to provide a longer power supply to devices and equipment. In the future, this technology will extend to other industries.
Printed circuit boards made according to this technology will be used in the construction of aircraft, the production of drones, as well as in the development of electronic communications.
fruit energy
A group of researchers is looking at new ways to power mobile devices while tackling the problem of food waste. Vincent Gomez, a chemical engineer at the University of Sydney, and his team turn foul-smelling durian waste,
and jackfruit, the world's largest, into supercapacitors capable of charging mobile phones, tablets and laptops in minutes. Ultra-capacitive capacitors are an alternative way to store energy.
Supercapacitors are usually made of expensive materials such as graphene, but Gomez's team turns leftover durian and jackfruit into carbonaceous aerogels - a porous, ultra-lightweight solid - that has exceptional natural energy storage properties.
The team heats up the inedible squishy core of the fruit, freeze-dries it and then puts it in an oven at temperatures above 1,500 degrees Celsius. The team then molds the light, porous black product into the electrodes of low-cost supercapacitors.
Supercapacitors can be charged in just 30 seconds and may be used to provide power for several devices, such as cell phones. The team hopes these supercapacitors will be used to store electricity from renewable sources to power vehicles and homes.
Durian, famous for its foul odor, may be used to manufacture a new generation of super thickeners
Before discovering these new uses for durian fruit, the foul-smelling fruit made headlines, as more than 70 percent of durian fruit was thrown into waste. The repulsive odor of its trash disrupted a plane's take-off in Indonesia and the evacuation of a library at the University of Canberra last year.
Mikhail Astakhov, a physical chemist at the National University of Science and Technology in Moscow, has conducted research to convert pigtail, a herb that contains toxic sap that can cause burns and blisters on human skin, into a raw material for the manufacture of supercapacitors capable of charging a phone.
