Bond strength and etch patterns vary between tooth type and between teeth within a tooth type. An 'ideal' enamel etch pattern is not essential for high bond strength. Objectives: The aim of the study ...

A logarithmic spiral with a diameter of 500 μm, approximately half the diameter of a sewing needle. Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led ...

On Sunday, the Minneapolis Institute of Art hosted the last day of “Rembrandt in America,” an exhibition it proudly described as “the largest selection of Rembrandt paintings assembled in the United ...

This study examines the relationship between enamel acid etch pattern and bond strength. Bond strength and etch patterns vary between tooth type and between teeth within a tooth type. An 'ideal' ...

Copper’s resistivity depends on its crystal structure, void volume, grain boundaries and material interface mismatch, which becomes more significant at smaller scales. The formation of copper (Cu) ...

Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a ...
