This is no detriment to the properties of titanium during forging or fabrication of its alloys; the oxide scale is removed after fabrication. In the liquid state, however, titanium is very reactive and reduces all known refractories. Titanium is not attacked by mineral acids at room temperature ...
(e.g.,aluminum,magnesium,calcium,sodium, potassium, or iron) assilicates. The oxidized form, as silicon dioxide and particularly as silicates, is also common in Earth’s crust and is an important component of Earth’s mantle. Its compounds also occur in all natural waters, in the atmosphere...

erogenic genes (Figure 2) and activates their transcription.Binding sitesfornuclear transcription factor Y(NFY),specificity protein 1(SP1) andcAMPresponse-element-binding protein (CREB), all common transcriptional coactivators for a variety of genes, are usually found in the sequence adjacent to the...
P element transposase catalyzes the mobility of P element DNA transposons within the Drosophila genome. P element transposase exhibits several unique properties, including the requirement for a guanosine triphosphate cofactor and the generation of long s
The present invention relates to structural elements and particularly to all metal elements into which nails may be driven for the purpose of attaching wood or other nail penetrable members or for the purpose of attaching two of the metal elements together. Among the objects of the invention......
This change was accepted in America, but questioned in Britain because it did not conform to the -ium suffix precedent set by potassium, sodium, magnesium, calcium, and strontium (all discovered by Davy). Thus, the aluminium spelling became the most common in Britain. The United States ...

concentrated nitric acid or acids containing dichromate—passivate iron (i.e., cause it to lose its normal chemical activity), however, much as they dochromium. Air-freewaterand dilute air-free hydroxides have little effect on the metal, but it is attacked by hot concentratedsodium hydroxide. ...
The preparation of pure titanium is difficult because of its reactivity. Titanium cannot be obtained by the common method of reducing theoxidewithcarbonbecause a very stable carbide is readily produced, and, moreover, the metal is quite reactive toward oxygen andnitrogenat elevated temperatures.
