The wettability between Nd2Fe14B and Nd-rich phases has been investigated through the sessile drop method. The compositions of prepared Nd-rich ingots were Nd72.0Fe26.1B1.9 (ternary) and Nd72Fe22.4Cu3.7B1.9(Cu-added). Nd-rich ingots were cut and put on a polished Nd2Fe14B plate and heated in a furnace. Contact angles…
The photoluminesecence (PL) of porous ZnO films modified with Eu 3+ ions was studied. The samples were fabricated by electrodeposition using eosin Y (EY) dye molecules. Scanning electron microscopy images and X-ray diffraction patterns showed that the porous films have nanometer-scale networks and become finer with in…
During the course of our study on the photochemistry of 1-alkoxy-9,10-anthraquinones, we have developed a second generation of a caged 4-hydroxy-trans-2-nonenal (4-HNE). As we optimized the anthraquinonyl chromophore to achieve water solubility, we studied the photochemistry of various substituents to understand their…
Quality is a multicriteria phenomenon that requires the simultaneous satisfaction of several criteria. In this study, we objectively represented the global quality of knits using a global quality index to simulate the consumer satisfaction degree. Every transformation function for each property gives the equivalent of…
We have deposited diamond-like carbon (DLC) films by plasma-enhanced chemical vapor deposition using CH 4 and Ar gases, and have investigated the structure, chemical bonding, adhesion strength, and tribological properties of the deposited films. The film properties have been characterized by visible Raman spectroscopy…
We present briefly a theoretical model of viscous friction in foams and concentrated emulsions, subject to steady shear deformation. In this model we calculate (1) energy dissipated inside the planar films between two neighboring bubbles/drops, which slide along each other dragged by the flow, and (2) energy dissipate…
Polyurethanes (PU) are a group of versatile polymers finding a lot of engineering uses due to their favorable and tunable properties and processing advantages. Although considerable amount of work has been reported on the polyurethane-montmorilonite nanocomposite, there is not much literature available on the polyuret…
The magnetoelectric (ME) effect in ferrite-piezoelectric ceramic composites based on a nickel ferrite spinel and lead zirconate titanate (PZT) has been theoretically and experimentally studied. Using the method of effective medium, an expression for the ME coefficient is obtained and its frequency dependence is analyz…
It is well known that an iron oxide layer formed on a surface of work piece plays an important role of lubricating properties in hot rolling. However, a few papers fully reported the influence of the iron oxide layer on lubricating properties. Therefore, we investigated the influence of compositions and thickness of t…
Abstract The characteristics of CO and NO molecules at Cu 2+ and Cr 3+ ion sites on the CuCr 2 O 4 (100) surface have been studied by first principles calculations based on spin‐polarized density functional theory (DFT). The calculated results show that adsorption energies for X‐down(C, N) adsorption vary in the order…
Microreactors can be used for continuous operation and precise control of heating conditions in chemical synthesis. Therefore, microreactors are expected to offer a more efficient strategy for obtaining homogeneous nanocrystals and easier of size control than the general batch reaction system. CdSe nanocrystals can be…
This contribution introduces a thermodynamically consistent, fully electro-mechanically coupled micro-mechanical model for ferroelectric materials. Adopting a phase field concept, in which the spontaneous polarization is used as order parameter, a Ginzburg-Landau type theory is formulated for the evolution of the orde…
The characteristics of chloride removal from simulated cast iron artefacts by electrochemical methods were studied. The effects of current and potential on chloride removal were investigated in both galvanostatic and potentiostatic modes. The composition of the rusts before and after treatment were analysed by X-ray d…
Vanadium pentaoxide micro-nano structures are grown on , , molybdenum (Mo), and fused silica (FS) substrates using direct vapor phase technique and studied using scanning electron and atomic force microscopy. The shape and size of micro-nano structures depend on the substrate. Belt-shaped structures formed on the subs…
This research used pulse and direct current methods to perform surface anodizing treatment of Mg-9 mass%Li-1 mass%Zn alloy (LZ91). The anodic films were analyzed with electrochemical impedance spectroscopy (EIS) for corrosion resistance. The impedance measurements show that the resistance value of anodic films made by…
The demand for paper yarn has increased as a textile fabric because of its light weight and low static electricity. However, paper yarn wrinkles easily and its softness and stretching properties are low. So we attempted to improve the stretching property of paper yarn by the high-pressure steam method which could prov…
The corrosion behavior of both tin-plated carbon steel and aluminum (Al 1100) in NaCl solutions were studied using electrochemical impedance spectroscopy (EIS). The study objectives were to compare their corrosion behavior in concentrated brine solution, establish the equivalent electrical circuit diagrams of their co…
Bulk metallic glasses have interesting combination of physical, chemical, mechanical, and magnetic properties which make them attractive for a variety of applications. Consequently there has been a lot of interest in understanding the structure and properties of these materials. More varied applications can be sought…
The Al 0.016 Zn 0.984 O (AZO) and Al 0.016 In 0.003 Zn 0.981 O (AIZO) thin films were grown on Corning 1737 glass substrates by pulsed laser deposition and they were investigated for the structural, electrical, and optical properties as a function of deposition temperature. The crystallinity of the films increases wit…
