MOF thin films with bi-aromatic linkers grown by molecular layer deposition -

Thin films of metal–organic frameworks (MOFs) are promising for a wide range of applications including membranes for separations and sensor materials in microelectronics. Growth of such thin films using atomic/molecular layer deposition (ALD/MLD) has recently been demonstrated; however, the range of examples is still narrow. Here, we expand the repertory of gas-phase MOF thin film […]

Morphological and mechanical characterization of composite bone cement containing polymethylmethacrylate matrix functionalized with trimethoxysilyl and bioactive glass -

Abstract Medical polymers of biostable nature (e.g. polymethylmetacrylate, PMMA) are widely used in various clinical applications. In this study, novel PMMA-based composite bone cement was prepared. Bioactive glass (BAG) particulate filler (30 wt%) was added to enhance potentially the integration of bone to the cement. The polymer matrix was functionalized with trimethoxysilyl to achieve an interfacial […]

Surface structure of fiber-reinforced composite implant and its effect on the attachment of implant to simulating bone material -

Fiber-reinforced composite (FRC) made of polymethyl methacrylate (PMMA) and E-glass fibers has been developed for bone segment defect reconstructions. It has been shown that exposed glass fibers predispose intergration of implant to bone. The aim of this study was to investigate how fibers of the implant surface can be exposed by solvent treatment and how the exposed fibers with different orientations effect the attachment of the implant to a bone simulating material

Porosity and mould filling of titanium castings -

A vacuum/Ar pressure casting machine was used to study porosity and mould filling of cast bridges of Ti. Two series of experiments were carried out

Porosity in posterior composite resins -

The percent pore area and the mean pore size were measured in specimens made of nine brands of composite resin restorative materials. The overall percent porosity ranged from 0.01 to 4.5%
