Several grams of caesium salt were recorded in about 11,600 gallons of mineral water. The caesium was found by using spectrum analysis which picked up bright blue lines. It was the first element to be discovered using this method. Cesium metal was first produced in 1882 using electrolysis. Ce...
Perhaps unsurprisingly, a variety of remedies can be found to treat sore feet. Robert Turner’s,Botanologia the Brittish physician, or, the nature and vertues of English plantsadvocated anointing feet with the herbs ‘ladies bedstraw or gallium’ before they undertook a journey. There was even...
Thallium, Tl, is the element with atomic number 81 and lies just below indium in the periodic table (same column as boron, aluminium, and gallium). It’s tasteless, colourless, and odourless and would be undetectable if sprinkled into food or a drink in a restaurant. Thallium ions have ...
The melting gallium under it would soak into the aluminum, disrupting its structure and causing it to become as soft and weak as wet paper. The burning sulfur would spill into thebromine. Bromine is liquid at roomtemperature, a property it shares with only one other element-mercury. It's ...
Doping is the process of adding impurities to an element in order to affect its electrical properties. Because silicon is abundant on the planet, it is fairly inexpensive. Chips are purpose-built devices that can be employed in a variety of industries, including aerospace, automotive,...
There's no rush,though,because most of these elements are so unstable that they can be created only in particle accelerators and don’t exist for more than a few minutes.If you had100,000atoms of Livermorium (element116),after a secondyou’d have oneleft-and a few hundred millisecondslate...
Substitution is an element of the politically much-discussed technology openness, which is a field of tension required by technology flexibility on the one hand, and strategic decisions, necessary in making a long-term investment commitment, and their consequences on the other hand. In this decision...
According to Jack Kilby, the man who created the integrated circuit, an integrated circuit is a semiconductor piece in which every element of an electronic circuit is completely integrated. An integrated circuit, in terms of technology, is an electronic circuit or device made by d...
P-type or n-type solar cells mix crystalline silicon, gallium, or boron to create silicon ingot. When phosphorus is added to the mix, the cells can conduct electricity. The silicon ingot is then cut into thin sheets and coated with an anti-reflective layer. Then, narrow slits are cut in...
