What if your refrigerator were better, silent and highly technological? A team of scientists believes it is possible – and has taken the first steps. Technology can open doors for innovation in various fields.
A Revolution in Cooling and Capturing Technologies: All thanks to the Hierarchically Controlled Super-Rede Fine Films), built by a Johns Hopkins APL team, which almost double the efficiency of refrigeration.
One of this year published in Nature It shows that there is an alternative to current, highly bulky cooling systems, consumers of a lot of energy and chemical dependents that can damage the environment.
Thermoelectric refrigeration, explains A, transfers heat using electrons in specialized semiconductor materialseliminating the need for moving parts or chemical fluids.
“This practical refrigeration demonstration using new thermoelectric materials shows the Capabilities of Fine films Chess built through nanoengineering ”. said Rama Venkatasubramanian, lead researcher of the joint project and chief technologist in thermoelectrics in APL.
“Marks a significant leap in cooling technology and paves the way to translate advances into thermoelectric materials into practical, large -scale and energetically efficient refrigeration applications,” says the scientist.
Using Chess materials, the APL team has achieved an improvement of almost 100% in efficiency.
“Let’s use Chemical Metal-Organic Vapor Deposition (MOCVD) To produce Chess materials, a method known for their scalability, cost and ability to support large volume production ”, explained the engineer Jon Pierce.
And it’s not just for domestic refrigerators that innovation opens doors. Jeff Maranchi, APL exploration programs manager, summarizes possible future applications.
“In addition to improve tactile systems next generation, prostheses and interfaces man-machine, this opens the doors to scalable energy capture technologies for applications that go from computers to spaceships – Capabilities that were not viable with ancient and bulky thermoelectric devices, ”he says.
