Characterization of functionalized calcium carbonate as a new pharmaceutical excipient [PDF]

, 2014
Excipients are indispensable functional components, which are used to develop innovative, robust, and reproducible formulations with good patient compliance due to optimized plasma concentrations and less side effects.

Fabrication and evaluation of the mechanical properties of reinforced biodegradable magnesium scaffolds using the space holder method [PDF]

Alexandria Dental Journal
Introduction: Magnesium metallic biomaterials have drawn attention as a promising bone substitute material because they can degrade spontaneously and have mechanical properties similar to those of bone.

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Effects of powder conditioning on the quality, microstructure and mechanical properties of sintered titanium alloys

, 2015
A small amount of internal lubricant (Stearic acid (SA) or Magnesium stearate (MgSt)) was added to Ti powder for the purpose of improving the compressibility and the green density homogeneity.

The Inhalation Characteristics of Patients When They Use Different Dry Powder Inhalers

, 2015
Background: The characteristics of each inhalation maneuver when patients use dry powder inhalers (DPIs) are important, because they control the quality of the emitted dose.

Production and Characterization of Pb-Carbon Composite for Manufacturing Metal Grids Applied in Lead-Acid Batteries

Materials Research
For decades, lead-acid batteries have been supplying power to electrical systems through redox reactions involving Pb and PbO2. However, the energy supply capacity is inherently constrained by low energy density and challenges associated with charge ...

Characterization of the Wetting and Dewetting Behavior of Powders

KONA Powder and Particle Journal, 2007
Experimental procedures for characterizing the wetting behavior of powders are reviewed. The fundamental processes involved in wetting–passage from one state of two-phase equilibrium (solid/gas and liquid/gas) through a three-phase condition (solid/liquid/gas) to a second two-phase condition (solid/liquid and liquid/gas)–are evaluated.

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines

Advanced Engineering Materials, EarlyView.
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.
