Where to find Glassy carbon?

Glassy carbon, also called vitreous carbon, is a non-graphitizing carbon which combines glassy and ceramic properties with those of graphite. The most important properties are high temperature resistance, hardness (7 Mohs), low density, low electrical resistance, low friction, low thermal resistance, extreme resistance to chemical attack and impermeability to gases and liquids. Glassy carbon is widely used as an electrode material in electrochemistry, as well as for high temperature crucibles and as a component of some prosthetic devices, and can be fabricated as different shapes, sizes and sections.
The structure of glassy carbon has long been a subject of debate. Early structural models assumed that both sp2- and sp3-bonded atoms were present, but it is now known that glassy carbon is 100% sp2. However, more recent research has suggested that glassy carbon has a fullerene-related structure.
Note that glassy carbon should not be confused with amorphous carbon. This from IUPAC: "Glass-like carbon cannot be described as amorphous carbon because it consists of two-dimensional structural elements and does not exhibit "dangling" bonds." It exhibits a conchoidal fracture.
Properties
Glassy carbon electrode (GCE) in aqueous solutions is considered to be an inert electrode for hydronium ion reduction.
The difference of 2.1 V is attributed to the properties of platinum which stabilizes a covalent Pt-H bond.

What is Magnesium powder used for?

Magnesium is a chemical element with the symbol Mg, atomic number 12, and common oxidation number +2. It is an alkaline earth metal and the eighth most abundant element in the Earth's crust and ninth in the known universe as a whole.
In human biology, magnesium is the eleventh most abundant element by mass in the human body; its ions are essential to all living cells, where they play a major role in manipulating important biological polyphosphate compounds like ATP, DNA, and RNA. Hundreds of enzymes thus require magnesium ions to function. Magnesium compounds are used medicinally as common laxatives, antacids, and in a number of situations where stabilization of abnormal nerve excitation and blood vessel spasm is required. Magnesium ions are sour to the taste, and in low concentrations they help to impart a natural tartness to fresh mineral waters.
Biological Applications
Magnesium is a vital component of a healthy human diet. Human magnesium deficiency (including conditions that show few overt symptoms) is relatively rare although only 32% of the United States meet the RDA-DRI; low levels of magnesium in the body has been associated with the development of a number of human illnesses such as asthma, diabetes, and osteoporosis.
Numerous magnesium dietary supplements are available. Magnesium oxide, one of the most common because it has high magnesium content per weight, has been reported to be the least bioavailable. Magnesium citrate has been reported as more bioavailable than oxide or amino-acid chelate (glycinate) forms.
Excess magnesium in the blood is freely filtered at the kidneys, and for this reason it is difficult to overdose on magnesium from dietary sources alone. With supplements, overdose is possible, however, particularly in people with poor renal function; occasionally, with use of high cathartic doses of magnesium salts, severe hypermagnesemia has been reported to occur even without renal dysfunction. Alcoholism can produce a magnesium deficiency, which is easily reversed by oral or parenteral administration, depending on the degree of deficiency.

Applications of Resorcinol

Resorcinol (or resorcin) is a dihydroxy benzene. It is the 1,3-isomer of benzenediol with the formula C6H4(OH)2.
Properties
Resorcinol crystallizes from benzene as colorless needles that are readily soluble in water, alcohol, and ether, but insoluble in chloroform and carbon disulfide. It reduces Fehling’s solution and ammoniacal silver solutions. It does not form a precipitate with lead acetate solution, as the isomeric pyrocatechol does. Iron(III) chloride colors its aqueous solution a dark-violet, and bromine water precipitates tribromoresorcin. These properties are what give it its use as a colouring agent for certain chromatography experiments. Sodium amalgam reduces it to dihydroresorcin, which when heated to 150 to 160 °C with concentrated barium hydroxide solution gives γ-acetylbutyric acid (D. Vorlgnder); when fused with potassium hydroxide, resorcinol yields phloroglucin, pyrocatechol, and diresorcin. It condenses with acids or acid chlorides, in the presence of dehydrating agents, to oxyketones, e.g. with zinc chloride and glacial acetic acid at 145 °C it yields resacetophenone (HO)2C6H3~CO.CH3. With the anhydrides of dibasic acids, it yields fluoresceins. When heated with calcium chloride—ammonia to 200 °C it yields meta-dioxydiphenylamine. With sodium nitrite it forms a water-soluble blue dye, which is turned red by acids, and is used as an indicator, under the name of lacmoid. It condenses readily with aldehydes, yielding with formaldehyde, on the addition of catalytic hydrochloric acid, methylene diresorcin [(HO)C6H3(O)]2•CH2. Reaction with chloral hydrate in the presence of potassium bisulfate yields the lactone of tetra-oxydiphenyl methane carboxylic acid. In alcoholic solution it condenses with sodium acetoacetate to form 4-methylumbelliferone.
Applications

Crown Ether is a macrocyclic polyether whose structure contains hydrogen, carbon and oxygen atoms. Each oxygen atoms are confined between two carbon atoms and exhibits a conformation with a hole (accordingly called "crown"). The common names of Crown Ethers have a prefix to designate the total number of atoms in the cycle and a suffix to designate the number of oxygen atoms in the cycle. For example, 15-crown-5 is composed of 15 atoms in the cycle, 5 of which are O and 10 of which are C.
As an ether, Dicyclohexano-18-crown 6-Ether is soluble in non-polar solvents. They are capable of strong solvency binding cations in their central cavity. The exterior of the ring is hydrophobic. The size of the interior central cavity, fused ring system, and side chains and functional groups determine the solvency capacity of the cation and the power of hydrophobic.

Functions of Laccaic Acid from Lacca

Description
Laccaic Acid from Lacca is a red colored natural dye produced by the insect Laccifer lacca or Coccus lacca. It is obtained in large amounts as a by-product of the shellac industry and has been considered for general use as a food coloring agent. Laccaic acid is found to have no mutagenic activity as assessed by two short-term assays: the Salmonella/microsome mutagenicity test, and the ØX fidelity assay. However, laccaic acid did inhibit metabolic cooperation in Chinese hamster V79 cells. These results suggest that laccaic acid should be tested in animals with particular emphasis on in vivo models for tumor promotion.
Function of Laccaic Acid from Lacca
With the function of natural food red color pigment, it is widely used in baked food, beverages of fruit vegetable juice (pulp), fruit flavoured beverages,soda pop, compound seasonings, jam, ice cream, ham, sausage,chocolate and candy products, it has good coloring effect
