|
| On the positive side, standard metal halide offers high lumens per watt,, and fairly long life, both of which are important to building operators. |
|
| All carbocations are strong alkylating agents with a high affinity for groups which donate or share their electrons, such as halide ions, hydroxyl anions and amines. |
|
| Black and white photographic emulsions are composed of layers of silver halide crystals, with additional small amounts of various sensitizing agents, suspended in gelatin. |
|
| Our HID products mainly include these types of electrical parts: sodium lamp, metal halide bulb, and mercury lamp. |
|
| When the shutter of your camera opens for that fraction of a second, photons of light stream in and strike the silver halide grains suspended in the gelatin emulsion. |
|
| With the use of metal-halide lamps an excellent colour rendering is ensured. Furthermore the light of a metal halide lamp contrasts strongly with that of approaching roads, resulting in improved visual awareness. |
|
| Lather, rinse, repeat, and we end up with a batwing distribution that makes all the metal halide fixtures green with envy. |
|
| At the same time, the silver anode is oxidized to form a silver halide. |
|
| When a hydrogen halide adds to the carbon-carbon triple bond of an alkyne, addition of the first molecule is faster than the second, and a vinylic halide can be isolated. |
|
| The data show that electrocarboxylation of benzyl chloride reacting with CO2 can occur, but butyl halide in the presence of CO2 cannot produce the electrocarboxylation product amylic acid. |
|
| Traditional photochromic eyeglasses are generally alkali boroaluminosilicates with 0.01 to 0.1 percent silver halide and a small amount of copper. |
|
| As an option, the Amaryllis is available with a dichroic glass reflector for metal halide lamps with ceramic arc tube or high-pressure sodium lamps. |
|
| Nucleophilic aromatic substitution of nitro-substituted aryl halides probably proceeds by attachment of the nucleophile to the aromatic ring in a step that precedes loss of the halide leaving group. |
|
|
|
| Despite the palaver, the silver halide communion is hugely satisfying. |
