Effect of Pore Size and Porosity on the Biomechanical

2015/6/5Five types of porous Nickel-Titanium (NiTi) alloy samples of different porosities and pore sizes were fabricated. According to compressive and fracture strengths, three groups of porous NiTi alloy samples underwent further cytocompatibility experiments. Porous NiTi alloys exhibited a lower Young's modulus (2.0 GPa ~ 0.8 GPa). Both compressive strength (108.8 MPa ~ 56.2 MPa) and fracture

Effect of Nanostructured and Open

A nanostructured, porous NCM cathode material is investigated regarding its behavior during electrode processing and electrochemical performance. The results are related to the densely packed NCM original material from which the nanostructure has been derived. Chemical composition and structural parameters are not affected by the nanostructuring process; changes are limited to the particle

Role of the Oxide Support on the Structural and Chemical

1 In this contribution, the particle size effect on CO2 hydrogenation to hydrocarbons over iron-based catalysts was deconvoluted into the effects on primary and secondary reactions. With a particle size range of 2.5-12.9 nm, the overall selectivity of C2+ hydrocarbons increases continuously, while that of CO decreases with the increasing size.

Wet chemical synthesis of nanocrystalline hydroxyapatite

2018/8/15An increase in pH and sintering temperature resulted in the growth and coalescence of crystals resulting in a porous capsular morphology. The FTIR analysis confirmed the reduction of carbonate stretching modes with an increase in pH and H-O-H antisymmetric stretching mode is eliminated for powders sintered at 900C confirming the formation of stable and porous HAp powders.

Effects of Surface Morphology of Ceramic Materials on

Ceramic scaffolds are widely studied in the tissue engineering field due to their potential in medical applications as bone substitutes or as bone-filling materials. The purpose of this study was to investigate the effect of surface morphology of nanostructure thin films of ZnAlsub2/subOsub4/sub prepared by spray pyrolysis and bulk pellets of polycrystalline ZnAlsub2/subOsub4

The effect of cure cycle on microstructure and mechanical

Carbon fibre reinforced thermoset composites make for lighter and stronger structures and are widely used for secondary and primary structures of commercial airplanes. The cure cycle is important to achieve a high quality of composite components. Cure path dependency for thermoset composites has received increasing interest from automotive and aerospace researchers as fast cure cycles are

Structure, morphology and surface properties of

The crystallites are non-porous and exhibit a rough surface incorporating a high concentration of low-coordinated surface sites. In agreement with the small particle size, the powder has a high specific surface area (200 m 2 g –1 ), which surmounts that of commercially available materials by a factor 3.

Additional evidence that the SiNWs were fully porous will be given below by considering the effect of different chemical treatments on their structure and morphology. Short SiNWs on p + Si formed at shorter etching times are also porous; however, no porous layer at the interface of the nanowires with the Si substrate is discerned.

Superhydrophobic Coating Fabrication for Metal Protection

2021/4/30Both the duty cycle and the coating morphology were the same base on the effect of pulse-on time. As the pulse-on time was extensive, sharper cones covered with shapeless secondary nuclei were seen. These components discussed above effectiveness on coating's morphology affected the cathodic overpotential and ion mass transfer system.
