Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications.

Dr. Edwin L. Thomas, professor in the Department of Materials Science and Engineering, and a team of researchers from Texas A&M University and Yonsei University recently discovered a helicoidal-shaped ...

Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

As logic and memory semiconductor devices approach the limits of Moore’s Law, the requirements for accuracy in layer transfer become increasingly stringent. One leading silicon wafer manufacturer ...

Drexel researchers have shown that a recently discovered deformation phenomenon, called ripplocation, occurs in bulk materials when constrained during compression. Every material can bend and break.

(Nanowerk News) Nanocrystals as protective coatings for advanced gas turbine and jet engines are receiving a lot of attention for their many advantageous mechanical properties, including their ...

Epitaxial growth is a fundamental process in semiconductor manufacturing. It refers to depositing a thin, crystal layer on a crystal substrate, with a specific orientation. This layer closely ...

Researchers recently discovered a helicoidal-shaped defect in layered polymers, uncovering how solvents can diffuse through layers and produce color changes. Dr. Edwin L. Thomas, professor in the ...
