This tiny US flag — just a few nanometers wide and invisible to the naked eye — is arguably the world’s smallest image of Old Glory, according to its creators at the University of Texas at Dallas. In an experiment, the nanoflag pattern emerged unexpectedly as sheets of the “stripe” material — molybdenum ditelluride —

Picture of the high energy resolution electron source developed by Bocquet and co-workers. Due to the geometrical constraints induced by the use of a hemispherical electron analyzer, part of the electron source had to be redesigned to bridge the large distance between the sample and the high energy resolution electron source.

This knowledge can lead to a better understanding of the functions of biomolecules and to tailored medicines.

The work could overcome the problem of hydrogen alloy embrittlement that has led to catastrophic failures in major engineering and building projects.

Though chaos theory says it’s basically impossible to

Visual comparison of printed surface before smoothing (1), with smoothing by conventional methods (2) and by 3D-CMF (3). CMF result (a-3) is more uniform than polishing (a-2), and CMF (b-3) accurately preserves more desired surface detail than solvent vapor method (b-2).Credit: Waseda University Waseda University researchers have developed a process to dramatically improve the quality
