21. Kirkaldy also developed methods for examining the microstructure of metals using optical microscopy. 22. Catalyst structure controls polymer microstructure , which ultimately determines macromolecular properties and applications. 23. They are using a finite element method that accounts for the known microstructure . 24. Pulp chemistry has a signififcant influence on nanocellulose microstructure . 25. The microstructure of the titanium disulfide greatly affects the intercalation and deintercalation kinetics. 26. Their tubes have two layers with different microstructure ( Vinn, 2008 ). 27. Researchers produced an artificial tooth whose microstructure mimicked that of a real tooth. 28. No two pearls have exactly the same microstructure . 29. The microstructure of materials reveals these defects, so that they can be studied. 30. These sequences have found consistent sex differences in human corpus callosal morphology and microstructure .
