High Young's Modulus With High Damping Capacity of Porous Alumina

In this paper, a method of producing high Young's modulus with high internal friction coefficient using porous ceramics is reported by clarifying the relationship between principal properties (Youngfs modulus and damping capacity) and sintering mechanisms.

Fabrication of Chemical Mechanical Polishing (CMP) Pad Dresser by Using Chemical Reaction Between Diamond Abrasive Grains and Titanium Matrix

CMP pad was fabricated by a pulsed electric current sintering method. The attachment of diamond grains after sintering was investigated to obtain a minimum requirement of TiC layer for a stronger anchoring effect.

Controlling Rheology by Changing the Size, Zeta Potential and Shape of Particles

Many materials in use today are disperse systems where one substance (often particulate) is dispersed in another phase. This “Ten Ways” guides you through some of the fundamental properties of the dispersed system and demonstrates how these affect the rheological properties.

Preparation of Stacked Polypyrrole-Coated Non-Woven Fabrics for an Electromagnetic Wave-Absorbing Sheet

New electromagnetic wave-absorbing sheets was formed by piling up ten pieces of polypyrrole nanoparticles-coated non-woven fabrics with specific resistivity. The piled conductive non -woven fabrics are promising radar-absorbent materials.

Effect of K+ Doping on the Phase Transformation of TiO2 Nanoparticles

In our work, using the sol-gel method, we prepared pure and K⁺ doped TiO₂ powders and characterized by means of XRD, TEM, SEM, EDS and UV-Vis
absorption.

Transparent Cr-Doped Al2O3 Made by Pulsed Electric Current Sintering Process

Pure corundum (Al₂O₃) is a rare mineral, perfectly colourless and transparent. Small amounts of metallic elements such as chromium, iron, titanium or vanadium can substitute for aluminium in the corundum crystal structure, giving rise to many colour variations.
