Investigation of the mechanism of mercury removal from silver- amalgam alloy [PDF]

Journal of the Serbian Chemical Society, 2004
An investigation of silver dental amalgam decomposition and the mercury removal mechanism was performed. The decomposition process was analyzed during thermal treatment in the temperature interval from 400 °C to 850 °C and for times from 0.5 to 7.5 h ...

The steady-state creep behavior of dental amalgam

, 1968
The steady-state creep behavior of a dental amalgam subjected to tensile stresses of 500 to 4000 psi (3.4 X 10^6 to 2.8 X 10^7 N/m2) was investigated over the temperature range of 23 to 52 C (296 to 325 K).

Automated particle analysis of D.B. Cooper's tie

Journal of Forensic Sciences, EarlyView.
Abstract Automated particle analysis (APA) using scanning electron microscopy (SEM) and energy‐dispersive x‐ray spectrometry (EDS) is a well‐known method in forensics, especially as it is applied to gunshot residue analysis. Here we describe the analysis of particles lifted from D.B. Cooper's tie, which was left on the hijacked plane in 1971.

Model‐Based Cost‐Effectiveness of Direct Restorations: Amalgam Dominates

Community Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives A phase‐down of dental amalgam use has been mandated and the feasibility of its phase‐out in England by 2030 is being explored. Amalgam use in English National Health Service (NHS) care still predominates for posterior restorations, though access to this care is increasingly limited.
