Research ArticleOpen accessEvery word in the titleResearch in the Improvement of Wettability of Micro-Structure in Patterned ElectrodepositionLi Guangyang, Wang Hong, Yuan Yang et al.Problem statement: The high aspect-ratio electrodeposition was widely used in the manufacture of non-silicon MEMS devices. The wetting of high aspect-ratio micro-structure in electrolyte was important to the uniformity of micro-structure. Approach: In this study, to enhance the wettability of micro-structures in electrolyte, the effect of Sodium Dodecyl Sulfate (SDS) and O2 plasma surface modification were discussed. Contact Angles (CA) … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,275 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Complexing Agent on Electrochemical Micro Machining of Stainless SteelChen Hui, Wang Yu-Kui, Wang Zhen-Long, Zhao Wan-ShengProblem statement: Electrochemical Machining (ECM) is a prospective technique in micro machining. The productions of work piece in ECM are precipitation of hydroxide, which will block the machining gap. To prevent the formation of hydroxide, acids were often used. To machining work piece which is not acid-resistant, acids are not suitable. Approach: This study is conducted to find the effects … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,113 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Methodology for the Selection of Micro-Assembly TechniquesDario Antonelli, Gualtiero Fantoni, Marcello Porta, Marco SantochiProblem statement: The study addressed the problem of selecting the appropriate microassembly techniques according to the micro-part features. Actually, in the micro-domain, the choice of the correct assembly technique is highly dependent on the micro-part characteristics such as shape, geometry and material. Approach: Since there was an incomplete and unstructured knowledge about the micro-assembly, the study proposed a Decision Support … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,176 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleAn Assessment of Compressive Size Effect of Plane Concrete Using Combination of Micro-Plane Damage Based Model and 3D Finite Elements ApproachM. Labibzadeh, S. A. Sadrnejad, M. NaisipourIn recent years, the material behavior dependence of laboratory concrete specimens built with the same concrete mixture under the same load conditions to their geometrical sizes is well established. This phenomenon which is observed not only in concrete but also in most quasi-brittle materials such as rock, ceramic or composite materials is now called as size effect. Many of the … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,005 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCrack Analysis of Concrete Arch Dams Using Micro-Planes Damage Based Constitutive RelationsM. Labibzadeh, S.A. SadrnejadAmong the various numerical simulating models of plane concrete, the micro-planes models have an excellent position.
