Integrated SPM probes with NEMS technology
Abstract
Two kinds of integrated scanning probe microscope (SPM) probes are developed. The first kind is AFM probes realized with a novel masked“maskless combined etching process. Both the nano-tips for scanning and the bending cantilevers are simultaneously formed with the masked“maskless combined anisotropic etching technique. The simultaneous formation method effectively avoids damage to the previously ....etc

CANTILEVER TECHNIQUE IN NANOTECHNOLOGY
What is a cantilever ??
A cantilever is a beam supported on only one end. The beam carries the load to the support where it is resisted by moment and shear stress
Cantilevered beams are the most ubiquitous structures in the field of micro electromechanical systems (MEMS
The MEMS cantilevers are commonly made as unimorphs or bimorphs:
 UNIMORPH: A unimorph is a cantilever that consists of one activ ....etc

ABSTRACT
Given the rapidly increasing data volumes that are downloaded onto mobile devices such as cell phones and PDAs, there is a growing demand for suitable storage media with more and more capacity. At CeBIT, IBM for the first time shows the prototype of the MEMS- Micro Electrical Mechanical System- assembly of a nanomechanical storage system known internally as the millipede project. Using revolutionary nanotechnology, scientists at the IBM Zurich Research Laboratory, Switzerland, have made it to the millionths o ....etc

Abstract:
The atomic force microscope (AFM) or scanning force microscope (SFM) is a very high-resolution type of scanning probe microscopy, with demonstrated resolution of fractions of ananometer, more than 1000 times better than the optical diffraction limit. The precursor to the AFM, the scanning tunneling microscope, was developed by Gerd Binnig and Heinrich Rohrer in the early 1980s, a development that earned them the Nobel Prize for Physics in 1986. Binnig,Quate and Gerber invented the first AFM in 1986. The AFM is one of the forem ....etc

1. ABSTRACT
Cracks present in machine parts affect their vibrational behaviour like the fundamental frequency and the resonance. This case is usual in machine parts subjected to fatigue type of loading. In this paper, the resonance response of a cracked cantilever beam has been studied based on fracture mechanics quantities like strain energy release rate, stress intensity factor and compliance. The vibration behaviour of a cantilever beam with cracks at fixed end and at the mid span has been analyzed ....etc

ABSTRACT
In the future, the current method of magnetically storing data may reach its limit of maximum achievable density. Hence we need a data storage technology which has high storage capacity and is small in size. The solution is Thermomechanical data storage. Thermomechanical Data Storage is a data storage scheme in which nanometer sized pits on a plastic disc represent digital data. This data storage concept combines ultrahigh density, terabit capacity, small form factor and high data rates. By using this concept, we w ....etc

All microscopes which provide images of atoms on or in the surface of any body is called atomic force microscope or the AFM, while all those microscopes which uses the principle of the atomic force microscopes are called as scanning probe microscope or the SPMâ„¢S.
These scanning probe microscopes work by measuring a local property such as height ,optical absorbtion magnetism etc ,by scanning over the sample by measuring the above property and providing the image on the television,with the probe or ....etc

1 .INTRODUCTION

In the 21st century, the nanometer will very likely play a role similar to the one played by the micrometer in the 20th century The nanometer scale will presumably pervade the field of data storage. In magnetic storage today, there is no clear-cut way to achieve the nanometer scale in all three dimensions. The basis for storage in the 21st century might still be magnetism. Within a few years, however, magnetic storage technology will arrive at a stage of its exciting and successful evolution at which fund ....etc

Introduction
The millipede high-density data storage system is based on micromechanical (MEMS*) components borrowed from atomic force microscopy (AFM). Tiny depressions created with an AFM tip in a polymer medium represent stored data bits that can then be read back by the same tip. Data written in this way can also be erased using the same tip, and the polymer medium can be reused thousands of times. This thermomechanical storage technique is capable of achieving data densities exceeding 1 Tb/in², well beyond the expected limits o ....etc

Human-Structure Interaction in Cantilever Grandstands
There is a risk that excessive vibration in long span cantilever grandstands can betriggered by the spectators synchronising their jumps to the music played. If thejumping frequeny excites a resonance of the grandstand, large force could begenerated. This thesis studies human-structure interaction in cantilever grandstands,with emphasis on modelling the passive and jumping crowds, and analysing theresponse of a single degree-of-freedom (SDOF) structural ....etc
