A family of lead clusters with precious metal cores

Metal Abundances in the Cool-Cores of Galaxy Clusters

We use XMM-Newton data to carry out a detailed study of the Si, Fe and Ni abundances in the cool cores of a representative sample of 26 local clusters. We have performed a careful evaluation of the systematic uncertainties related to the instruments, the plasma codes and the spectral modeling finding that the major source of uncertainty is in the plasma codes. Our Si, Fe, Ni, Si/Fe and Ni/Fe di...

A Comparative Evaluation of Shear Bond Strength of Creation Ceramic Veneer to Metal and Zirconia Cores

Abstract Background and Aim: High chipping rates of the veneering porcelain of zirconia ceramic restorations have been reported in clinical studies. Thus, the shear bond strength (SBS) between the zirconia core and veneering porcelain requires investigation. Materials and Methods: In this in-vitro study, at first, using a computer-aided design/computer-aided manufacturing (CAD/CAM) machine, 1...

Retrieval of Precious Metal from Waste Effluent at Precious Plate Inc. in Niagara Falls , NY

Precious Plate, Inc. is a local electroplating company that uses a variety of metals during its processes. Post-deposition, the aqueous phase used is designated for disposal, which poses problems regarding the metal content of the waste stream. First, EPA regulations mandate that metals be kept below specific levels. Even at levels capable of meeting EPA limits, the loss of metals within their ...

Gold nanoparticles: a revival in precious metal administration to patients.

Gold has been used as a therapeutic agent to treat a wide variety of rheumatic diseases including psoriatic arthritis, juvenile arthritis, and discoid lupus erythematosus. Although the use of gold has been largely superseded by newer drugs, gold nanoparticles are being used effectively in laboratory based clinical diagnostic methods while concurrently showing great promise in vivo either as a d...
