pearlitic steelThe pronounced mechanical property of pearlitic steels highly correlates with the ferrite (bcc-Fe)/cementite (Fe3C) boundaries inside. Unraveling the interface structure at an atomic level is essential for interpreting the material's property. In the present study, using aberration-...
These cations then pass through a (variable) electric or magnetic field that deflects each cation’s path to an extent that depends on both its mass and charge (similar to how the path of a large steel ball bearing rolling past a magnet is deflected to a lesser extent that that of a ...
Objectives Describe the experiments of Thomson, Millikan, Rutherford, Chadwick and Bohr and explain how they contributed to our present understanding of atomic structure. Describe the mass and charge differences among electrons, protons and neutrons. Define atomic number, mass number and isotopes in ter...
Atomic structure of the nanowire for various transition-metal dichalcogenides: (a) atomic structural model of the nanowire, where dashed red triangles indicate the orientation of each layer in the nanowire, and (b) experimental (left) and simulated (right) STEM Z-contrast images of individual MoSe...

Through the eyepieces a lighted screen revealed both external and internal structure of the tiny insect—only it wasn’t an insect. Gaynor felt a curious, unbelieving numbness. Clearly visible in the screen was the tiny solar motor and an incredibly complicated drive mechanism for the wings. ...
Controlling the precise growth of atoms is necessary to achieve manipulation of atomic composition and atomic position, regulation of electronic structure, and an understanding of reactions at the atomic level. Herein, we report a facile method for order
Fig. 1.21 shows cracks in a steel component operating in hydrogen atmosphere. The hydrogen breaks up the crystallites at the grain boundaries into micrometer scale particles. Hydrogen molecules had entered the crystalline structure of the metal crystals and allowed cracks to run through the normally...

As a result, the nucleated twin structure penetrates quickly through the cross section of nanocrystals, enabling fast twin growth via facile migration of twin boundaries leading to large uniform plastic deformation. The present work reveals a size-dependent transition in the nucleation- and growth-...
