Rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] through lutetium [Lu]). The elements cerium through lutetium are called the lanthanides, but many scientists also, though incorrectly, call those

Method of Gold Extraction using Borax

In Benguet province, a group of miners have been using the mercury-free gravity-borax method (GBM) for gold extraction for decades. This method basically requires the same equipment as the amalgamation methods. However, after the rod milling, an ore concentrate holding the heavy minerals is produced by using a launder (gold sluice) and a gold washing pan.

18-1-2016P-cadherin induces CCM. Because P-cadherin is up-regulated in aggressive tumors and associated with cell invasiveness, we investigated its role in cell migration by monitoring mouse C2C12 cells that express P-cadherin (C2C12 Pcad; Fig. 1 a) after removal of a physical barrier to provide free space into which confluent cells could migrate.. As a control, C2C12 cells expressing only empty

Gold Extraction Using Nitric Acid

Gold rings, chains and necklaces are often alloys of gold mixed with a percentage of silver, rather than being gold alone. While various procedures can purify gold, using substances like saltpeter or concrete, today nitric acid combined with hydrochloric adid can produce aqua regia to make the procedure as easy as possible.

Cellular traction forces: a useful parameter in cancer

Traction force microscopy consists of embedding fluorescent particles in a thin (tens of microns) gel layer and calculating the traction forces of cells cultured on the gel from the displacement of the particles. 11,12 This method is easy to implement experimentally and has recently been demonstrated to be amenable to high spatial resolution force tracking. 13 However, the calculation of the

Whey Protein: Top 10 Best Whey Protein

Whey protein is one of the two proteins, other than casein, found in milk. In natural form, it can be used either by extracting casein from milk or as a by-product of cheese making. The whey protein is rich in amino acids and low in lactose content which makes it a complete protein. It contains nine essential amino acids.

How to Refine Gold With Nitric Acid

Once the two acids have been applied to the gold, the dissolving process has begun. The mixture of gold and aqua regia will become extremely hot as the gold begins to dissolve. Leave it undisturbed overnight, allowing time for the gold to be fully dissolved. The next day, strain the acid through a Buchner filter funnel to remove particles of undesired material. Repeat the process until the

Liquid–liquid extraction

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.
