Effects of Heat Treatment of ZnS Nanoparticles Prepared by Hydrothermal Synthesis on Microstructure and Optical Properties in Spark Plasma Sintering (SPS)

Hong Y.W., Yeo S.Y., Paik J.H., Cho J-H., Jeong Y.H., Yun J.S., Park W.I., Korea Institute of Ceramic Engineering & Technology, KR

Zinc sulfide (ZnS) is one of the most widely used infrared transmitting window and lens materials for systems operating in the long wave range (8~12 ㎛). ZnS nanoparticles have been intensively studied because of their [...]

Nano-layer and micro-structure technologies for energy efficiency and sustainability

Hebrink T.J., 3M Company, US

Multilayer optical film technologies made with hundreds of nanolayers and microstructured film technologies can be used to manage building energy while maintaining architectural aesthetics. For example, visibly transparent (invisible) infrared mirror films are useful for [...]

Properties and characterisation of an aluminum – silicon nitride fiber powder metal composite

Dougherty T., Xu Y., Nuenz Limited, NZ

There is an increasing demand for new light-weighting materials to improve fuel-efficiency in the automobile and aerospace industries. This has led to an increase in the use of aluminum over traditional metals, such as steel, [...]

Comparative HRTEM Examination of Carbon Black and Soot Structures

Spry J.M., Compton S.P., MVA Scientific Consultants, US

Soot is a major source of airborne particulate and typically contains primary particles which are less than one micrometer in diameter. Soot particles form as an undesired combustion by-product originating from a variety of different [...]

The preparation and characterization of the Graphene-Like YBO3:Ce3+

Wang Y., Wang Z.Z., Hu X.Y., Wang Y., Wang Z.Z., Zhan S.C., Sun Q., Sun X., Miao H., Sun Q., Sun X., Hao Y.Y., Northwest University, CN

In this study, a new material of Graphene-Like YBO3:Ce3+ phosphors was synthesized by solvothermal method and layered by liquid exfoliation treatment, and it is the material with layered structure. SEM image shows that the thickness [...]

Electropulsing induced nanophase decomposition and structural characteristics of film of alloy ZA27

Zhu Y., To S., Lee W.B., Hong Kong Polytechnic University, CN

Nanophases appear very stable and hardly decompose completely under conventional thermal aging, because of their strong preferred crystal orienttation. As one of the advanced processes, electropulsing has been recognized for its efficiency in reducing residual [...]

Microstructures and Electrochemical Properties of Rapidly-solidified Si-Mn-Cr alloys

Han H.W., Ahn D.K., Ahn H-J, Ahn D.K., Ahn H-J, Park W-W, Sohn K.Y., Inje University, KR

In this work, the microstructure and electrochemical properties of Si-Mn-Cr alloy specimens prepared by a rapid solidification process and a conventionally-solidified process have been investigated. Si70Mn15Cr15 alloy ribbons by atomic ratio were prepared by two [...]

Microstructure and tribological properties of CrTiAlN nanoscale composite coatings on 65Mn steels deposited by multi arc ion plating technology

Cai Z., Zhang P., Academy of Armored Force Engineering, CN

In order to improve the life of piston rings, a multicomponent CrTiAlN composite coatings with different chemical composition are deposited on the surface of 65Mn steels by multi-ion plating technology in a gas mixture of [...]

Construction and properties of zein-based cell supports and scaffolds

Padua G.W., Wang Q., Wang Y., Wang Q., Wang Y., University of Illinois Urbana-Champaign, US

Zein, a protein abundant in corn, is capable of self-assembly and may form a variety of structural morphologies (Wang et al 2004, Wang et al 2008a). Zein micro-fibers (Figure 1.), films, and sponges (Figure 2) [...]
