Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging ...
Graphene encapsulation provides unprecedented view of the diffusion and rotation of fullerene molecu
Carbon is one of the most versatile elements: it forms the basis for an enormous number of chemical compounds, it has several allotropes of different dimensionality, and it exhibits many different ...
In CdS nanocrystals, photoexcited holes rapidly become trapped at the particle surface. The dynamics of these trapped holes have profound consequences for the photophysics and photochemistry of these ...
(Phys.org)—As long as the temperature is above absolute zero, gas molecules are always in constant random motion. They may diffuse—or spread out—through three-dimensional space or, in a process called ...
Integrated circuits have become increasingly more reliable as the technology has progressed, but even a perfectly produced processor operated under the most rigorously maintained environment will fail ...
The basic principles of diffusion MRI (dMRI) were introduced in the mid-1980s. This method is deeply rooted in the concept that, during their diffusion-driven displacements, molecules probe tissue ...
