By Gary M. Verigin, DDS, CTN As more people become aware of the health risks of mercury amalgam fillings, you see more dental practices marketing themselves as “metal-free.” Sounds great, no? It’s also inaccurate – and not just because these dentists often do place metal restorations such as gold crowns. As dental materials expert Jess Clifford has noted, “There is no such…

Early in my career I worked for a dealership that sold production boats, every one of which was equipped with painted aluminum arches. Invariably, the paint would blister, in some cases before the vessels were offloaded from delivery trailers, and warranty claims were dutifully submitted, which the builder, to its credit, promptly paid. In an effort to stem the cash flow, the…

We use the term oxidative phosphorylation to describe how 2 molecules of FADH2 and NADH (produced in the Citric Acid cycle) are used to make ATP. We use the term “oxidative” because oxygen accepts an electron while the gradient made by the movement of electrons powers the creation ATP. But why do we even need oxygen? Can’t the electrons just float around the cell? Well they…

Antimony() oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions only with hydrolysis. Antimony() oxide is an amphoteric oxide, it dissolves in aqueous sodium hydroxide solution to give…

Oxygen is -2 therefore there are 3 oxygen s so -2 x 3 = -6. Overall molecule there is no charge so for it to be neutral iron must have an oxidation state of +3 as there are two iron atoms. You have 3 atoms of Oxygen in the molecule which gives you the total of oxidation states 3 * -2= -6 To balance it off you have two atoms of Fe with oxidation state 3 which gives you 2*3=6…

Extraction of Aluminium - Hall (Electrolytic) Cell. The steel container is coated with carbon (graphite) and this is the negative electrode (cathode). Electrolysis of the alumina/cryolite solution gives aluminium at the cathode and oxygen at the anode. Al3+ + 3e- Al (aluminium metal at the (-)cathode) 2O2- - 4e- O2 (oxygen gas at the (+)anode) Aluminium is more dense than the…

Although aluminum oxide is certainly abrasive, it is also a skin irritant with a very questionably safety record. In any case, it is unquestionably unpleasant. If it gets into your eyes, it can scratch your cornea. If it gets into your ears, it can cause earaches. If it gets into your mouth, you will experience the unpleasant sensation of tooth enamel grinding away until it’s…

This final installment of the Abrasive Blasting Media series will discuss the merits of using both Steel Shot and Steel Grit for blasting. Both of these media types are produced from scrap steel which is melted, modified and then solidified into a generally round shape (Shot) or angular particles (Grit). Steel Shot produces a very smooth finish on the surface of metals. The…

Other hardness measurement numbers are found, such as, Brinell, Rockwell and Knoops. The Vickers hardness is up to about HV 500 about 1.04 times the Brinell hardness but most of the time hardness of the anodic oxide layer is measure by Vickers. Knoops hardness is almost identical with Vickers hardness except for the form of the diamond. In this testing method the diamond has…

Chemistry is used in everyday life, from making food to breathing air. Chemical reactions are what creates life, makes food into energy, and even what causes food to rot. When… you balance equations, you are learning the amount of elements used in the reactants, or found in the products. If you do not balance the equation, you will only know what you started with, and not the…
