Recent Patents on Materials Science - Volume 8, Issue 1, 2015

In this review article, we are mainly focused on discussion and analysis of techniques reported in patents and studies in the field of CO2 capture and sequestration from atmospheric air and flue gases with the use of pure Ca(OH)2 dispersions and Ca(OH)2-comprising sorbents. The discussed CO2 capture techniques are classified in terms of the composition of Ca(OH)2-comprising sorbents. The physicochemical aspects of the Read More

Proton exchange membrane (PEM) fuel cell receives special attention as an alternative power device for various industrial applications because of its excellent energy conversion efficiency, high power density, low operating temperature, convenient fuel supply, longer life time and low emission. The prospective commercial applications of PEM fuel cell comprise laptop, computers, cellular phones, military back power packs, scoot Read More

In this contribution, patents and literature concerning the development and application of tool materials and coating materials are reviewed including patents relating to the selection and preparation of materials for recent lathe-type tools. To address the needs of machining in the future, new types of coating materials and patents dealing with coating methods such as PVD (Physical Vapor Deposition) and CVD (Chemical V Read More

Recently, many patents have been developed for developing the measuring methods of grinding temperature. Some of them could measure temperature of grinding zones more accurately, which enables to control thermal damage of work piece and wear of grinding wheel effectively. Among these patents, one is for a grinding temperature measurement based on inverse heat conduction problem. It inlays a piece of thi Read More

It is well known that a naturally matured loofah has some distinct inherent properties including extremely low density and high absorbability, due to its unique fibrous microstructure and macro-cellular architecture including the spatial configuration of voids and solids. In this paper, we focus on patents and literature related to the development of a three-dimensional (3D) lightweight metallic structure by means of a design bio-in Read More

In order to study excellent properties of the magnetorheological fluids (MRFs), some relevant patents and researches are studied. Experiment materials, experimental method and test methods are elaborated, and two types of carriers are used to prepare MRFs samples with different additives addition. The microstructures of both uncoated magnetic particles and coated magnetic particles are observed by scanning el Read More
