Based on the above theoretical mineral physics approach, the team examined the mechanical behavior and thermodynamic properties of high-angle tilt grain boundaries in (Mg,Fe)O ferropericlase, the ...

Grain boundaries in polycrystalline graphene are an obstacle to electron transport. However, cunning refinements in growth techniques push the limits to obtain super-sized single-crystal domains.

Grain boundary mobility was found to vary significantly with pressure. Surprisingly, strong grain boundary weakening was observed with increasing depth, ...

"These grain boundaries have an enormous influence on the durability and overall performance of a material," says Dr. Vivek Devulapalli who has performed the microscopy work of the study.

Grain boundary dynamics driven by magnetically induced circulation at the void interface of 2D colloidal crystals. Science Advances , 2022; 8 (22) DOI: 10.1126/sciadv.abn5715 Cite This Page : ...

Similarly, a grain boundary migrates unidirectionally when subjected to oscillatory driving forces or temperature," said Qiu Caihao, a Ph.D. student in MSE and first author of the paper.

Grain boundaries play an important role in the electrical behaviour of some materials. Control of grain boundaries can influence how well a material performs. A method for measuring the structure of ...

Low-Angle Grain Boundaries (LAGBs): LAGBs have a misorientation angle less than 15° and are composed of an array of dislocations.They have a relatively low interfacial energy and maintain a coherent ...

However, understanding how grain boundaries affect heat flow in this material, is crucial to determining how good it might be for thermal management applications. “Until now, researchers have studied ...

On the other hand, grain boundaries might be exploited as plasmon reflectors and phase retarders – which are essential components for future graphene-based plasmonic circuits. Indeed, the team says ...

(Nanowerk News) Using state-of-the-art microscopy and simulation techniques, an international research team systematically observed how iron atoms alter the structure of grain boundaries in titanium.
