The presence of water in the solution is reportedly necessary; the electron rich amalgam will oxidize aluminium and generate hydrogen gas from water, creating aluminium hydroxide (Al(OH) 3) and free mercury. The electrons from the aluminium reduce mercuric Hg 2+ ion [clarification needed] to metallic mercury. The metallic mercury can then form ...
A 2005 position statement from the Canadian Dental Association (CDA) states "current scientific evidence on the use of dental amalgam supports that amalgam is an effective and safe filling material that provides a long-lasting solution for a broad range of clinical situations. The CDA has established its position based on the current consensus ...
Amalgam is a metallic filling material composed from a mixture of mercury (from 43% to 54%) and a powdered alloy made mostly of silver, tin, zinc and copper, commonly called the amalgam alloy. [16] Amalgam does not adhere to tooth structure without the aid of cements or use of techniques which lock in the filling, using the same principles as a ...
Aluminium amalgam may be prepared by either grinding aluminium pellets or wire in mercury, or by allowing aluminium wire or foil to react with a solution of mercuric chloride. This amalgam is used as a reagent to reduce compounds, such as the reduction of imines to amines. The aluminium is the ultimate electron donor, and the mercury serves to ...
The New England Children's Amalgam Trial (NECAT), a randomized controlled trial, yielded results "consistent with previous reports suggesting that the longevity of amalgam is higher than that of resin-based compomer in primary teeth, according to a 2007 review of the study, [22] with some similar claims in a 2003 paper, [30] and composites in ...
"The Alabama Solution" is one of the most powerful exposés of the inhumanity of the American prison system I’ve ever seen. Directed by Andrew Jarecki ("Capturing the Friedmans," "The Jinx") and ...
Aluminum amalgam (Al/Hg) may be used for the chemoselective reduction of α-sulfonylated carbonyl groups. Carboxylic acid derivatives, acetals, thioacetals, amines, alcohols, and isolated double bonds are all inert to Al/Hg. Selective desulfonylation may be carried out on β-hydroxy sulfones without reductive elimination. [16
