New Material Breaks World Record Turning Heat Into Electricity
The new material is so effective that it could be used to provide energy for sensors or even small computer processors. Instead of connecting small electrical devices to cables, they could generate their own electricity from temperature differences.
Bioprinting: Living cells in a 3D printer
With a new process living cells can be integrated into fine structures created in a 3D printer - extremely fast and with very high resolution.
Artificial intelligence: Parking a car with only 12 neurons
A naturally grown brain works quite differently than an ordinary computer program. It does not use code consisting of clear logical instructions, it is a network of cells that communicate with each other. Simulating such networks on a computer can help to solve problems which are difficult to break down into logical operations.
Amazingly 'green' synthesis method for high-tech dyes
Dyes that are also of great interest for organic electronics have recently been prepared and crystallised. All that is required is just water, albeit under highly unusual conditions.
A new kind of quantum bits in two dimensions
Combining two ultra-thin material layers yields new possibilities for quantum electronics. A research team presents strongly tunable quantum systems in Printed Electronics World.
Graphene able to transport huge currents on the nano scale
New experiments have shown that it is possible for extremely high currents to pass through graphene, a form of carbon. This allows imbalances in electric charge to be rapidly rectified.
3D printing nano structures made of pure gold
Researchers have discovered a novel way to fabricate pure gold nanostructures using an additive direct-write lithography technique. An electron beam is used to turn an auriferous organic compound into pure gold.
For the first time, magnets can be made with a 3D printer
For the first time ever, permanent magnets can be produced using a 3D printer. This allows magnets to be produced in complex forms and precisely customised magnetic fields, required, for example, in magnetic sensors.
Graphene: A quantum of current
An international team of researchers has now explained the peculiar behaviour of electrons moving through narrow constrictions in a graphene layer.
Photo-electrochemical cell can store the energy of ultraviolet light
By combining highly specialised new materials scientists have managed to combine high temperature photovoltaics with an electrochemical cell.
