Brighter blobs are strontium atoms, weaker are titanium.
Just visible in the lower simulation are oxygen atoms. A see what we get transmission electron microscopy experiment has produced the world s highest-resolution image of a crystal structure, enabling researchers to see atomic details less than an angstrom in size. It s a doubly improved clarity over previous TEM images. Pennycook and Nellist are both native Englanders who have found East Tennessee to be very fruitful ground for science. In Pennycook and Nellist s images, atomic details only 0.78 angstrom apart can be discerned, which is an improvement over the conventional limit of 1.6 to 1.8 angstroms by a factor of two, says Pennycook.
