this paper describes the effects of induced magnetic field and partial slip on the peristaltic flow of a couple stress fluids in an asymmetric channel. the two dimensional equation of couple stress fluid are simplified by making the assumptions of long wave length and low reynolds number. the exact solutions of reduced momentum equation and magnetic force function have been computed in wave fra...

This paper presents a proof-of-concept prototype of a micro force sensing mobile microrobot. The design consists of a planar, elastic mechanism serving as computer vision-based force sensor module, while the microrobot body is made from a magnetic layer driven by a magnetic field. From observing the deformation of the elastic mechanism, manipulation forces can be determined. The deformation is ...

Several species of Magnetotactic bacteria have been discovered recently. These bacteria synthesize intracellular magnetic nanoparticles in specific sizes and shapes and arrange them in chains. These particles called magnetosomes and can be used for drug-delivery, cell-targeting and hyperthermia. Magnetotactic bacteria navigate along the magnetic field; this process is known as ‘magnetotaxis’ wh...

Background: Curcuma longa generally known as turmeric includes curcuminoids and sesquiterpenoids as components, which are known to have antioxidative, anticarcinogenic, and anti-inflammatory activities. Iron, magnetite, and hematite as a micronutrient play an important role in physiological and chemical processes. Chitosan is a natural polymer derived from chitin and is recognized as versatile ...

Magnetic abrasive finishing can be classified as a non-traditional super finishing method for finishing surfaces with different shapes and working materials like flat plates, shafts, bearings parts, screws, tubes and many other mechanical parts that need good surface finishing properties. MAF is effective in polishing, cleaning, deburring and burnishing metal parts. The most important parameter...

Since the invention of the scanning tunneling microscope (STM) in 1981 and the atomic force microscope (AFM) in 1986, over 5,000 publications have cited the article “Atomic Force Microscope” by G. Binnig, C.F. Quate, and C. Gerber (published in Physical Review Letters, 1986). This article presents a short review on the operating principle and possible applications of AFM with special attention ...

Magnetism-based microsystems, as those dedicated to immunoaffinity separations or (bio)chemical reactions, take benefit of the large surface area-to-volume ratio provided by the immobilized magnetic beads, thus increasing the sensitivity of the analysis. As the sensitivity is directly linked to the efficiency of the magnetic bead capture, this paper presents a simple method to enhance the captu...
