Lasers, high-power light-emitting diodes, high-performance integrated circuits and microprocessors, optoelectronic devices and several biomedical instruments require stable thermal regimes and effective cooling. Thermoelectric microcooling systems are designed for these purposes. The working principle of thermoelectric modules is based on the Peltier effect — heating or cooling at an electrified junction of two different conductors. The closer the cooling element is to the heat source, the more effectively it works.
Scheme of the two-stage thermoelectric module
RMT Ltd. manufactures thermoelements using nanosized powder hot extrusion from bismuth telluride nanopowder, which allows for an additional 15-20 °C of cooling for one-stage coolers. These coolers will meet demand from manufacturers of optoelectronic devices such as night-vision equipment and orientation sensors. Notable features of the RMT project are the full automation of production and the development of a technology for thin-film heat transfer. The project will further miniaturize microcoolers by reducing the size of thermal elements to 0.2 mm as well as the density of the packaging and raising cooling performance by up to 40 watts/cm2.With their outstanding reliability, the micromodules developed in this project exceed the best devices available in the global market today.
The Visual Science Company has cooperated with the RUSNANO Group since 2008, creating a wide range of high quality graphic information materials. Various infographics have been designed to demonstrate the technologies developed and implemented by RUSNANO project companies. The aim of each project is to demonstrate the principle of technology, nanotechnological components of the project and the advantages of the chosen solution compared with analogues.
The work of Visual Science is carried out in a single sheet or slide format. The modular structure of the infographics makes it possible to use it both as a whole piece or as separate components, which is convenient for preparing website illustrations or project reports or publications. Thus one material helps to solve almost all the issues with illustrating the information about the project.
The target audience for these graphics includes professionals in relevant areas, and a wide range of specialists in different fields without a technical background. Scientific accuracy, combined with the optimum degree of generalization allow for communicating equally effectively with target audiences with different background.
All the graphics have been used by the RUSNANO Group for 5 years or more. As usual, the feature of the Visual Science workflow includes the entire spectrum of tasks ranging from analyzing the scientific literature of the project to the preparation of the final graphics on the company’s side that allows saving valuable time of our customers.
I would like to express my gratitude to Visual Science and all its employees who participated in the Second Nanotechnology International Forum organization. Thank you for your professionalism and the high quality product
