ABOUT US

 

NanoMEGAS 

was created in 2004 by a team of scientists and experts in the field of electron crystallography and catalysis. Electron  crystallography has been  initially  developed in Russia  from the early 1950 (Vainstein and  Zvyagin et al), J.Cowley (Arizona State Univ USA) and later in 1990s by D.Dorset (Buffalo USA), J.Gjonnes (Oslo Norway) among  others using TEM microscopy.


Inspired by this  early  work  and  also contemporal work developed  with  precession   electron diffraction by Vincent and Midgley in Bristol UK(1994), our team developed and was the first to commercialize in 2004 a universal  precession device (« spinning star ») for TEM.


Being  an important  part /contribution of this scientific  «success  strory»  (and  being proud of it)  almost  10  years later  precession  diffraction / electron crystallography   applications  are present  in  almost  every major electron microscopy /X-Ray crystallography  scientific  congress, with  more than 180 publications (2004-2013) from various laboratories worldwide  and  dedicated issues  of major  scientfic microscopy  journals.


Our precession diffraction  related instrumentation is actually present in more than 75 laboratories all over the world. Our novel digital  DigiSTAR precession unit in combination with electron diffractometer Pleiades can be adapted to your commercial  TEM (100-400 kV old as well as brand  new)  and combine with  3d diffraction tomography to solve  nanocrystals structures, otherwise difficult  to solve by conventional  X-Ray diffraction  techniques.


Beam precession into the ASTAR device provides orientation and phase maps  at 1-3 nm  resolution (FEG-TEM)  for a variety of  materials  (metals, semiconductors, oxides etc..) without  any  need of  particular  specimen  preparation. Precession diffraction  can  be also very useful  to obtain STRAIN maps  at  2-4 nm resolution with  FEG-TEM (sensitivity < 2 x 10-4) , providing extremely important information for materials  scientists.  Precession  diffraction is also  useful  to enhance /optimize EELS / EDS spectra and allow to have better data. The  recently developed with our Partner  AppFive  TOPSPIN  platform  allows  the user to perform  advanced  analytical precession  diffraction experiments with  the TEM.


NanoMEGAS participates as an SME Partner to the largest EU project (ESTEEM-2) on transmission  electron microscopy  with  mission  to supply   with  expertise  on  electron  diffraction applications. We are active Partners of IUCr  (International Union of Crystallography/Electron Crystallography Comission). NanoMEGAS has collaborations  with  CNRS /INP  Grenoble/France, Univ of  Mainz /Germany , Univ  of Barcelona /Spain , IIT Pisa /Italy , CNR Bari, Univ of Leiden -Netherands  to develop new exciting   electron  crystallography  applications.
