Toughening β‐Ga2O3 via Mechanically Seeded Dislocations

open access: yesAdvanced Functional Materials, EarlyView.
β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

Study on Precision Grinding of Axisymmetrical Form. Mechanism of Form Generation.

open access: yesJournal of the Japan Society for Precision Engineering, 1996
In grinding of axisymmetrical surfaces, residual removal increases in peripheral region. Therefore, the surface profile becomes concave and the form accuracy deteriorates. In this paper, the mechanism of generating axisymmetrical form error is made clear by analyzing the change of grinding force. The following facts are revealed by experiments.

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus

open access: yesAdvanced Functional Materials, EarlyView.
The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...
