Capillary zone electrophoresis was used in the analysis of anions and cations in electroless plating bath samples. Examples described in this application note include the analysis of inorganic and organic anions in nickel-plating baths, cations in nickel-iron-cobalt-plating baths and metal-EDTA complexes in plating bath waste. Sample preparation was minimal, consisting merely of diluting the sa...

The first section of this chapter describes general pollution prevention techniques for plating solutions and covers housekeeping, monitoring, additives, equipment modification, and on-site recycling and recovery. The next section covers general issues in pollution prevention for cyanide-based plating. The next seven sections cover pollution prevention options for plating specific metals such a...

BACKGROUND Several strategies to reduce construct stiffness have been proposed to promote secondary bone healing following fracture fixation with locked bridge plating constructs. However, stiffness reduction is typically gained at the cost of construct strength. In the present study, we tested whether a novel strategy for stiffness reduction, termed far cortical locking, can significantly redu...

The Ni-B-P alloy coatings were made autocatalytically (electroless) using an alkaline plating bath with nickel chloride hexahydrate (NiCl2.6H2O) as the source of nickel ions, sodium borohydride (NaBH4) and sodium hypophosphite (NaH2PO2) as reducing agents and source of boron and phosphorous ions, respectively. The effects of bath concentrations on the plating rate, composition of coating, surfa...

In this study, we performed a network meta-analysis to compare the outcomes of seven most common surgical procedures to fix DRF, including bridging external fixation, non-bridging external fixation, K-wire fixation, plaster fixation, dorsal plating, volar plating, and dorsal and volar plating. Published studies were retrieved through PubMed, Embase and Cochrane Library databases. The database s...

As now constituted, the human tumor cloning assay performedin Petri dishes has several limitations including: (a) not all patients' tumors form colonies in the assay; (b) the plating efficiencies (number of colonies formed/numberof cells plated) are low; and (c) a large number of tumor cells are required to perform drug sensitivity testing. In this study the use of capillary tubes, as vessels i...

BACKGROUND Locking plates transmit load through fixed-angle locking screws instead of relying on plate-to-bone compression. Therefore, locking screws may induce higher stress at the screw-bone interface than that seen with conventional nonlocked plating. This study investigated whether locked plating in osteoporotic diaphyseal bone causes a greater periprosthetic fracture risk than conventional...

anatomically precontoured locking plates are intended to facilitate the fixation of articular fractures and particularly those associated with osteoporosis. fractures of the distal humerus are relatively uncommon injuries where operative intervention can be exceptionally challenging. the distal humeral trochlea provides a very narrow anatomical window through which to pass a fixed-angle locking...

High-throughput genomic approaches to gene function or target identification have led to the development and implementation of the 96-well format for many standard molecular biology manipulations. The apparatus described here, a Multichannel Plating Unit, is designed to plate out individual cultures efficientlyfrom standard 96-well culture blocks. Following transformation, aliquots of culture a...
