1. Aluminum anodization
The history of electrochemical oxidation of aluminum dates back to the beginning of the last century. Anodic treatment of aluminum were intensively investigated to obtain protective and decorative films on its surface [1]. More recently, applications of porous alumina with a huge surface area and a relatively narrow pore size distribution have been exploited [2]. For example, several attempts t...
متن کاملSelf-ordered anodic aluminum oxide formed by H2SO4 hard anodization.
The self-ordering of nanoporous anodic aluminum oxide (AAO) in the course of the hard anodization (HA) of aluminum in sulfuric acid (H2SO4) solutions at anodization voltages ranging from 27 to 80 V was investigated. Direct H2SO4-HA yielded AAOs with hexagonal pore arrays having interpore distances D(int) ranging from 72 to 145 nm. However, the AAOs were mechanically unstable and cracks formed a...
متن کاملThe Anodization of Aluminum for Nanotechnology Applications
This article is an introduction to anodization of aluminum, which is a subject of electrochemistry. Anodization of aluminum under a controlled electrochemical condition yields ordered porous alumina with a close-packed hexagonal array of cylindrical nanochannels. The diameter, density, and aspect ratio of pores can be tightly controlled by varying the anodization condition, which makes the poro...

شبکه خود سازمانده پرکاربردترین شبکه عصبی برای انجام خوشه بندی و کوانتیزه نمودن برداری است. از زمان معرفی این شبکه تاکنون، از این روش در مسائل مختلف در حوزه های گوناگون استفاده و توسعه ها و بهبودهای متعددی برای آن ارائه شده است. شبکه خودسازمانده از تعدادی سلول برای تخمین تابع توزیع الگوهای ورودی در فضای چندبعدی استفاده می کند. احتمال وجود سلول مرده مشکلی اساسی در الگوریتم شبکه خودسازمانده به حسا...
Mems Built–in-self-test Using Mls Mems Built–in-self-test Using Mls
This paper presents a Built-In-Self-Test (BIST) implementation of pseudo-random testing for Micro ElectroMechanical Systems (MEMS). The technique is based on Impulse Response (IR) evaluation using Maximum–Length Sequences (MLS). We will demonstrate the use of this technique and move forward to find the signature that is defined as the necessary samples of the impulse response needed to carry ou...
