What's the difference between copperplate and etched?
Copperplate
Definition:
(n.) A plate of polished copper on which a design or writing is engraved.
(n.) An impression on paper taken from such a plate.
Example Sentences:
(1) She composed her fiction in a copperplate hand, usually a single draft with very few corrections, in spiral-bound school notebooks from the Edinburgh stationer and bookseller James Thin.
(2) "He is capable of beautiful copperplate script, but can produce very different kinds of writing with very little resemblance to each other," Barker said.
(3) She has always hunted out old letters from antique markets, little scraps of billets-doux and deeds of sale, faint tracings of forgotten human hope in copperplate, the ink faded to brown and grey.
(4) A stylus with 45 degree angulation and an opposing copperplated lower arch of either human or Macaca fascicularis were used for approximation of the natural situation.
(5) Here you can get away.” On a wing dedicated to healthy, active living, motivational slogans have been painted in copperplate lettering above the cell doors reminding occupants: “Take care of your body; it’s the only place you have to live” or “Manners maketh the man”.
(6) Called the Jolly Roger, its walls were lined with real cutlasses and its leatherette-bound menus were decorated with compass points and written in an indecipherable copperplate script that made ordering an ice-cream float feel like a hunt for buried treasure.
(7) And they marvelled anew at her writing method: in copperplate handwriting, straight out in a single draft, into special spiral-bound notebooks imported from the Edinburgh stationers, James Thin.
Etched
Definition:
(imp. & p. p.) of Etch
Example Sentences:
(1) After permeabilization, with attendant partial extraction, the preparation can be fixed, then viewed by either deep-etch replication, or by high-resolution scanning electron microscopy, with structure of interest revealed in deep view.
(2) The freeze-etch technique was used to study the morphology of Treponema refringens (Nichols).
(3) A thorough dental prophylaxis before acid-etching of enamel is often recommended.
(4) The results of the rapid-freeze and deep-etch procedure showed that the ridges observed by the surface replica method consisted of linear arrangements of elliptical particles on the ES face of the plasma membrane.
(5) All the summer deals in graphical, Etch-a-sketch form .
(6) When either predictability or bond strength was considered independently, several bracket systems, coupled with a particular etch time, had either high predictability or high bond strength.
(7) This demineralization was similar to enamel acid etched with 50% phosphoric acid for 2 mn.
(8) This study evaluated the bond strength between glass ionomer cements and laser-etched dentin.
(9) Acid etching smooths and cleans the dentinal surface.
(10) Examination of apposed replicas and deep-etched specimens indicated that at least some of the IMPs extend through the T. pallidum outer membrane and are exposed on the surface of the organism.
(11) Isolated appressed chloroplast membranes, highly enriched in photosystem II (PSII) activity, were examined by freeze-etch electron microscopy.
(12) The technique of freeze-etching for electron microscopy applied to isolated islets of Langerhans has permitted a successful evaluation of emiocytotic events on the cell surface.
(13) The tensile bond strengths of the bonding resin to the etched enamel surfaces were not significantly different.
(14) The etched porcelain laminate veneer is a new conservative treatment that offers a solution to fractured, discolored, and worn anterior teeth.
(15) SEM and TEM examinations suggested that dentinal collagen exposed by the etching but not entangled and impregnated by poly (4-META-co-MMA) easily deteriorated by water during the longer immersion.
(16) The performance of a commercial double-propane-jet freezer (Balzers QFD 101) has been assessed, for rapid freezing of fresh tissues in freeze-etch work.
(17) The purpose of this in vitro study was to determine the tensile bond strengths (TBS) of several orthodontic bonding systems and orthodontic brackets to enamel surfaces exposed to different etching procedures.
(18) We find that freeze-drying is the most reliable and easy method for molecules that withstand distilled water; freeze-etching can be successfully applied to transmembrane proteins (even in the presence of detergents or salt); the glycerol-spray technique provides an excellent alternative to the cryotechniques in particular for studies of single linear molecules.
(19) After acid etching, filtration produced a 32-fold increase in permeation.
(20) On the corresponding PF face of the plasma membrane, linear arrangements of the intramembrane particles (IMPs) of about 8 nm in diameter were observed by both the deep-etch and freeze-fracture methods.
