With the addition of various ingredients, the greenish liquid gradually becomes a brownish colloid. The color-viscous material developed by the University of Toronto in Canada may pave the way for a new, cheap way to store renewable energy.
The study found that after the material was spread onto a metal belt and energized, the rate of breaking water molecules was three times higher than that of commonly used materials, and the cost was much lower. Zhang Bo, a visiting researcher at the University of Toronto, said that the magical colloidal material it developed could act as a catalyst to decompose water into hydrogen and oxygen.
The key to the relevant hydrolysis process is the use of relatively inexpensive and abundant tungsten metal. Tungsten itself does not decompose water, but it can change the properties of other components under the action of a catalyst, especially iron-cobalt oxides, thereby making water decomposition easier. Moreover, this new material can be made at room temperature and can be made to be as easy to use as a sticker.
The researchers said that the new colloidal material can promote the development of industrial-scale hydrolysis technology. During this process, oxygen as a by-product is usually released into the atmosphere while hydrogen is stored. Later, in the fuel cell, these hydrogens can recombine with oxygen to generate energy.
Storage has always been a problem that has plagued the renewable energy field. Battery technology has not provided a cheap and long-term means of storing large quantities of electrical energy. The advantage of the new technology is that it can store electricity generated by intermittent renewable energy sources (such as solar and wind energy) for use indefinitely in the future.
The new colloidal material is the first concrete result of the Bionic Energy Project funded by Canada’s Advanced Projects Institute (CIFAR). The project was led by Edward Sargent, a prominent energy expert at the University of Toronto. The research results were published in the latest issue of the journal Science. (Reporter Feng Weidong)
Thiocyanate (also known as rhodanide) is the anion [SCN]−. It is the conjugate base of thiocyanic acid. Common derivatives include the colourless salts Potassium Thiocyanate and Sodium Thiocyanate. Organic compounds containing the functional group SCN are also called thiocyanates. Mercury(II) thiocyanate was formerly used in pyrotechnics.
Thiocyanate is analogous to the cyanate ion, [OCN]−, wherein oxygen is replaced by sulfur. [SCN]− is one of the pseudohalides, due to the similarity of its reactions to that of halide ions. Thiocyanate used to be known as rhodanide (from a Greek word for rose) because of the red colour of its complexes with iron. Thiocyanate is produced by the reaction of elemental sulfur or thiosulfate with cyanide
Thiocyanate[4] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase.[5][6][7] Thus the complete absence of thiocyanate[8] or reduced thiocyanate[9] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.[10][11]
Thiocyanate is a potent competitive inhibitor of the thyroid sodium-iodide symporter.[12] Iodine is an essential component of thyroxine. Since thiocyanates will decrease iodide transport into the thyroid follicular cell, they will decrease the amount of thyroxine produced by the thyroid gland. As such, foodstuffs containing thiocyanate are best avoided by Iodide deficient hypothyroid patients.[13]
In the early 20th century, thiocyanate was used in the treatment of hypertension, but it is no longer used because of associated toxicity.[14] Sodium nitroprusside, a metabolite of which is thiocyanate, is however still used for the treatment of a hypertensive emergency. Rhodanese catalyzes the reaction of sodium nitroprusside with thiosulfate to form the metabolite thiocyanate
Our main Thiocyanates are Sodium Thiocyanate, Potassium Thiocyanate, ammonium thiocyanate.
