A novel surface texturing technique is introduced based on the bombardment using custom shots originally known as shot peening process describe in article number 2201730 by Sara Bagherifard and co-worker. Different textures are achievable through having distinct superficial designs upon full coverage peening. The concept proved simulations experiments.

Abstract Polyetheretherketone (PEEK) is an aromatic, semi-crystalline thermoplastic polymer with good wear resistance, corrosion superior mechanical properties, chemical stability and biocompatibility. While the elastic modulus of PEEK highly similar to that cortical bone, based on many such excellent material properties PEEK, it determined often used in intervertebral fusion, artificial joint ...

In this paper, Fe 3 O 4 @SiO 2 core/shell magnetic nanostructure has been synthesized and modified by N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS). Fe 3 O 4 @SiO 2 was used as a novel adsorbent for separation of hexachloroplatinic acid.X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR technique were used to characterize morphologies and surface te...

Correspondence to: Mohammad Amani Tehran email: [email protected] ABSTRACT In this study, color coordinates variation of spundyed polyester filament yarns subjected to the false twist texturing process was investigated. Furthermore, the effect of different processing parameters including D/Y ratio, twist, heater temperature, texturing speed, overfeed, the draw ratio and intermingling process on t...

In this paper we examine the methods of rendering implicit surfaces with a per-pixel approach. Ray tracing the implicit model directly has several benefits as opposed to processing tessellated meshes, but also invokes new kinds of problems. The main challenge is efficiently finding the first ray-surface intersection point where the surface is not given in an explicit form. Our implementation us...

This paper focuses on anti-reflective coatings monocrystalline silicon solar cells and the impact of front surface texturing. The reference wavelength is =700 nm, with its optimum refractive index (n = 3.7838) a reflectivity 33%. calculations were made basis layer thickness values indices that allow phase amplitude conditions chosen to be respected, namely (MgF2) (SiOxNy), (SiOx), (SiNx:H). Num...

The external quantum efficiency of solar cells can be improved by using texturing pyramid- and honeycomb-like structures with minimum reflection. In this study, we investigated the reflection properties of texturing structures through rigorous coupled-wave analysis and the three-dimensional finite-difference time domains (FDTD) method to analyze close-packed texturing structures. We also demons...
