Wireless Microfluidic Sensor for Metal Ion Detection in
· In the present work a wireless microfluidic sensor based on low-temperature cofired ceramic (LTCC) technology for real-time detection of metal ions in water is proposed. The wireless sensor is composed of a planar spiral inductor and parallel plate capacitor (LC) resonant antenna which integrates with the microchannel in the LTCC substrate between the capacitor plates. Aqueous solutions of

· Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens naturally in mineral deposits or as part of a manufacturing process used with metals ceramics plastics and other materials.The atoms in the materials diffuse across the boundaries of the particles fusing the

Methods for Synthesis of Nanoparticles and Fabrication of
· Sol-gel is a method for producing solid materials from small molecules. In this chemical procedure the sol (or solution) gradually evolves toward the formation of a gel-like diphasic system containing both a liquid phase and a solid phase the morphologies of which range from discrete particles to continuous polymer networks ().Ultrafine and uniform ceramic powders can be formed by precipitation.

A critical review of high entropy alloys and related
· 1. Introduction. The first results on multi-component and high entropy crystalline alloys were published in 2004 about 12 years ago. The two major new concepts of this approach include opening a vast unexplored realm of alloy compositions and the potential to influence solid solution phase stability through control of configurational entropy.
