Formulas may be patented. [4] An example is a mixture of 2-(4-alkoxyphenyl)-5-alkylpyrimidine with cyanobiphenyl, patented by Merck and Sharp Corporation. The patent that covered that specific mixture expired. [5] Most color LCD systems use the same technique, with color filters used to generate red, green, and blue subpixels.

The substance, IUPAC name (29H,31H-phthalocyaninato(2−)-N29,N30,N31,N32)copper(II), is known by many names [2] such as monastral blue, phthalo blue, helio blue, [3] thalo blue, Winsor blue, [4] phthalocyanine blue, C.I. Pigment Blue 15:2, [5] [6] copper phthalocyanine blue, [7] copper tetrabenzoporphyrazine, [8] Cu-phthaloblue, [9] P.B.15.2, [10] [11] [12] C.I. 74160, [13] [14] [15] and ...

In the 1830s, analog encoding methods, such as Morse code, were developed, allowing for transmitting information over long distances using electrical signals. [2] Electronic modulation was developed between 1832 and 1927 and was a crucial development in the history of telecommunications.
The color pattern consists of a pale tan to pinkish-tan ground color that becomes darker towards the foreline, overlaid with a series of 10–18 (13.4) crossbands. Characteristically, both the ground color and crossband pattern are pale in A. c. contortrix. These crossbands are light tan to pinkish-tan to pale brown in the center, but darker ...
2 Cu + O 2 → 2 CuO. For laboratory uses, copper(II) oxide is conveniently prepared by pyrolysis of copper(II) nitrate or basic copper(II) carbonate: [4] 2 Cu(NO 3) 2 → 2 CuO + 4 NO 2 + O 2 (180°C) Cu 2 (OH) 2 CO 3 → 2 CuO + CO 2 + H 2 O. Dehydration of cupric hydroxide has also been demonstrated: Cu(OH) 2 → CuO + H 2 O
The modern technique (abbreviation of modern technique of the pistol) is a method for using a handgun for self-defense, originated by firearms expert Jeff Cooper. [1] The modern technique uses a two-handed grip on the pistol and brings the weapon to eye level so that the sights may be used to aim at the target.
