   • 1978, American Laboratory - Volume 10, page 20:

     A greater number of elements may be detected by means of a thin pyrographite or glassy carbon microsupport (cross section 0.1-0.5 mm2), which is introduced into a high-temperature flame such as acetylene/nitrous oxide.

   • 1980, Anthony Delyannis, E Delyannis, Proceedings of the 7th International Symposium on Fresh Water from the Sea.:

     This structure is in contrast to asymmetric membranes in which thin salt barrier is formed during gelation and consist of the same material as the underlying microsupport.

   • 1998, Dieter Radaj, Cetin Morris Sonsino, Fatigue Assessment of Welded Joints by Local Approaches, →ISBN, page 122:

     A salient feature of the approach is the assessment of the microsupport effect at the mostly sharp toe and root notches of the welded joints according to the Neuber microstructural support hypothesis.

   • 2013, R. E. Spier, J. B. Griffiths, W. Berthold, Animal Cell Technology: Products of Today, Prospects for Tomorrow, →ISBN:

     The data reported here show that Dielectric spectroscopy can detect the uptake of serum proteins by the microsupport following the latter exposure to complete growth medium.

3. (mathematics) A closed involutive cone in the cotangent bundle of codirections in which the cohomology of the object does not propagate.
   • 2015, Vivek Shende, David Treumann, Harold Williams, Eric Zaslow, “Cluster varieties from Legendrian knots”, in arXiv‎^[1]:

     We show that many interesting spaces -- including all positroid strata and wild character varieties -- are moduli of constructible sheaves on a surface with microsupport in a Legendrian link.
