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' ...

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 ...

Researchers have a new low-cost method to carve delicate features onto semiconductor wafers using light -- and watch as it happens. The technique can monitor a semiconductor's surface as it is etched, ...

SERVI 1 showed complex spirals on the basal plane of cleaved zinc crystals after etching, and spiral terraced etch pits have been obtained on zinc crystals 2 grown from vapour using ‘Superoxol’ etch.

London-based designers Fabio Hendry and Martijn Rigters have used burnt human hair to create patterns on aluminium stools, which they are presenting at this year's IMM Cologne furniture fair. Hendry ...
