To make a kilo of rice, we need 2,450 liters of water. - The We Are Water...
LONDON, March 13, 2012 /PRNewswire/ -- Strategic Minerals Plc (AIM: SML), the magnetite focused iron ore producer and exploration company, is delighted to announce that it has entered into a commercial contract ("Contract") with a subsidiary of Glencore International PLC (LSE:GLEN), for the sale of iron ore concentrate from its Cobre Project in New Mexico, to Glencore AG. Under the terms of the Contract, the total quantity of magnetite to be made available to Glencore...
An international team of physicists has developed a method for taking ultrafast “sonograms” that can track the structural changes that take place within solid materials in trillionth-of-a-second intervals as they go through an important physical process called a phase transition. Common phase transitions include the melting of candle wax before it burns and dissolving sugar in water. They are purely structural changes that produce dramatic changes in a material’s physical properties...
Researchers from North Carolina State University have developed the first functional oxide thin films that can be used efficiently in electronics, opening the door to an array of new high-power devices and smart sensors. This is the first time that researchers have been able to produce positively charged (p-type) conduction and negatively charged (n-type) conduction in a single oxide material, launching a new era in oxide electronics. To make functional electronic devices, you need...
Clouds have a profound effect on the climate, but we know surprisingly little about how they form. Erika Sundén, researcher at the University of Gothenburg, Sweden, has studied how extremely small cloud particles can dispose of excess energy. This knowledge is necessary to understand processes in the atmosphere that affect global climate change. The models that have been built to describe climate change contain a major source of uncertainty, namely the effects of clouds. The UN...
WILMINGTON, Del., March 5, 2012 /PRNewswire/ -- Effective April 1, 2012, DuPont Titanium Technologies announces a price increase of 20 cents per pound (USD), or as permitted by contract, for all DuPont(TM) Ti?Pure® titanium dioxide (TiO2) sold in North America (United States and Canada) into coatings, plastics, laminates and specialty applications. This increase is in addition to any previously announced increases for North America. Price increases for DuPont(TM) RPS Vantage(TM)...
WILMINGTON, Del., March 1, 2012 /PRNewswire/ -- Effective April 1, 2012, DuPont Titanium Technologies announces a net price increase of 150 Euros per metric tonne, or as permitted by contract, for all DuPont(TM) Ti?Pure® titanium dioxide (TiO2) grades for all countries in which invoicing is in Euro, namely the countries of Western and Central Europe and the North African region. In addition, effective April 1, 2012, DuPont Titanium Technologies announces a net price increase of $200...
SINGAPORE, Feb. 29, 2012 /PRNewswire/ -- Effective April 1, 2012, DuPont Titanium Technologies announces a net price increase of $200 (USD) per metric ton for all DuPont(TM) Ti-Pure® titanium dioxide grades (TiO2) sold in Asia Pacific. DuPont Titanium Technologies is the world's largest manufacturer of titanium dioxide, serving customers globally in the coatings, paper and plastics industries. The company operates plants at DeLisle, Miss.; New Johnsonville, Tenn.; Edge Moor,...
The frigid McMurdo Dry Valleys in Antarctica are a cold, polar desert, yet the sandy soils there are frequently dotted with moist patches in the spring despite a lack of snowmelt and no possibility of rain. A new study, led by an Oregon State University geologist, has found that that the salty soils in the region actually suck moisture out of the atmosphere, raising the possibility that such a process could take place on Mars or on other planets. The study, which was supported by the...
Researchers at the universities of Granada and Barcelona have described for the first time the diffusion of liquid water through nanochannels in molecular terms; nanochannels are extremely tiny channels with a diameter of 1-100 nanometers that scientists use to study the behavior of molecules (nm. a unit of length in the metric system equal to one billionth of a meter that is used in the field of nanotechnology). This study might have an important impact on water desalinization and...

Indium is a chemical element in the periodic table that has the symbol In and atomic number 49. This rare, soft, malleable and easily fusible poor metal, is chemically similar to aluminium or gallium but looks more like zinc (zinc ores are also the primary source of this metal). Its current primary application is to form transparent electrodes from Indium tin oxide in liquid crystal displays. It is also widely used in thin-films to form lubricated layers (during World War II it was widely...
There are a number of iron oxides: Iron oxides Iron(II) oxide or ferrous oxide (FeO) The black-coloured powder in particular can cause explosions as it readily ignites. Iron(III) oxide or ferric oxide (Fe2O3) known in its natural state as hematite or haematite, but also purified for use as a coating in magnetic audio and computer media, where it is known as ferric oxide. Also known as rouge. Iron(II,III) oxide or ferrous ferric oxide (Fe3O4), better known as the black-coloured...
Limonite Limonite is a ferric hydrate of varying composition, the generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as Limonite often contains a varying amount of oxide compared to hydroxide. Together with hematite, it is mined as ore for the production of iron. Limonite is heavy and yellowish-brown. It is not a true mineral, however, but a mixture of similar hydrated iron oxide minerals, mostly Goethite. Limonite forms mostly in or near...
Magnetite is a magnetic mineral form of both iron(II) oxide and iron(III) oxide or (iron(II,III) oxide), with chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. Magnetite is the most magnetic of all the minerals on Earth, and these magnetic properties led to lodestone being used as an early form of magnetic compass. Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks as well as many sedimentary rocks. Magnetite is a...
