比利時(shí)NanoMEGAS  
比利時(shí)NanoMEGAS公司是一家致力于發(fā)展先進(jìn)的電子晶體學(xué)技術(shù)的高科技公司。目前公司開發(fā)的產(chǎn)品包括透射電鏡旋進(jìn)電子衍射技術(shù)、電子衍射計(jì)和透射電鏡晶體取向和晶相發(fā)布自動(dòng)分析系統(tǒng)等，這些先進(jìn)技術(shù)和設(shè)備可以安裝在100-400kV的所有透射電鏡（包括FEI、JEOL、日立、ZEISS等廠家的所有透射型號(hào)，有無(wú)STEM附件均可）上。

旋進(jìn)電子衍射技術(shù)將目前廣泛應(yīng)用的電子衍射方法擴(kuò)展到定量晶體學(xué)領(lǐng)域，是電子晶體學(xué)的重大發(fā)展。應(yīng)用旋進(jìn)電子衍射技術(shù)以后，透射電鏡的電子衍射強(qiáng)度接近于運(yùn)動(dòng)學(xué)理論數(shù)字，可以使用X射線晶體學(xué)的軟件和方法進(jìn)行處理，從而得到納米晶體的二維和三維晶體結(jié)構(gòu)。

透射電鏡晶體取向和晶相發(fā)布自動(dòng)分析系統(tǒng)類似于掃描電鏡上的EBSD（背散射電子衍射花樣）分析技術(shù)，但其分辨率更高（在場(chǎng)發(fā)射透射電鏡上可以達(dá)到5nm以下）、分析速度更快，而且適合于各種晶體類型。

NanoMEGAS was created in 2004 by a team of scientists and experts in the field of electron crystallography and catalysis.

Our tools are dedicated to help TEM and X-ray users to solve unknown nanocrystal structures using advanced electron diffraction tools in any TEM:

Our unique precession interface the Spinning Star in combination with electron diffractometer Pleiades can be adapted to any commercial TEM (100-400 kV , old as well as brand new) to convert them to powerful structure nanoanalysis tools.

Our scientists have a strong network of collaborations and research teams with leading Academic Institutions, including:

Université Libre de Bruxelles (ULB)
Instituto de Tecnología Quimíca/UPV Valencia
University of Stockholm
University of Leiden
SiMAP University of Grenoble
IC CNR Institute of Crystallography Bari
University of Portland, Oregon USA
International Center for Diffraction Data ICDD
