Biography:

Dr von Gratowski has her expertise in research in nanotechnology, nano-manipulation, nano-assembling, shape memory alloys. She has had invented and suggested frontier mechanical bottom up nano-assembling, nano-manufacturing and nano-fabrication of single nanodevices based on individual nano-objects using the smallest and the fastest shape memory alloy nanogripper. This technology opens up perspective of the creation of single nano/micro and macro devices from individual nanotubes, nanowires and other nano-objects. Mechanical bottom up nano assembling is going to overcome the presently existing barrier of the integration of variety of nanoobjects and nanodevices with each other and with convectional integrated circuits. Moreover, the novel technology will provide products not only with the next level high quality, but also extremely low cost. This breakthrough nanotechnology will be affordable for small groups with small modest budget in science, education and SME.

 

Abstract:

Nowadays many different types of nano-sized materials, like nanoparticles and nanostructures, especially 1D-nanotubes, nanowires (NWs), 2D-nanomaterials such as graphene etc. have been discovered and intensively studied. Nanomaterials as the bulk materials and also as single nanoobjects demonstrate the unique functional properties. Functional properties of single nanoobjects allowing to design many individual nanodevices based on single nanoobjects. Recently, many investigations have led to a wide range of proofs of the concept of individual nanoscale devices designed using single nanoobjects. Those individual nanodevices include NWs- and CNTs-based nano-sensors, FET, nanolasers, etc. Such single nanodevices represent attractive building blocks for a hierarchical assembly of micro/macrodevices. The bottleneck of the design of such nano/micro/macrodevices is missing of the technology for the creating and such single nanodevices and a hierarchical assembly of micro/macrodevices from those individual nanodevices.

 The report suggests frontier nanotechnology for the hierarchical assembling of           nano/micro/macroscopic functional devices using individual nanoscale building blocks.     There are 5 main steps in this “bottom-up” approach for the production of nanodevices:   1)  to tailor nanomaterials; 2) to worked out the surface of the nanomaterial; 3) cut   nanomaterials into individual components; 4) to organize these  components into   nanodevices; 5) to interconnect and unite single nanodevices together in micro/macro   World. The last 4th and 5th steps are still challenge in modern nanotechnology. In the   present report the prospective applications of the new 3D nanomanipulation system based   on the smallest and fastest in the World shape memory nanogrippers is discussed. This   design system is experimentally proved to provide 3D manipulation of the real nano-     objects like NW, grafene etc. In the report it is shown that this type of nanomanipulation   can be used for nanomanufacturing of nano/microdevices, using alternative “bottom-up”  mechanical nano-assembly. This breakthrough technology pretends in many cases to compete the manufacturing approaches based on expensive currently available “topdown” nanolithography
