UCLA doctoral student Yilin Wong noticed that some tiny dots had appeared on one of her samples, which had been accidentally ...

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 ...

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' ...

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 ...
