Extensive study on multilayered coating systems has been carried out to understand the scratch-induced damage mechanisms. The experimental results show that increase in soft base layer thickness improves the scratch resistance. The numerical analysis of the stress and strain field explains the mechanics behind the improvement in scratch resistance in the multilayered coating systems. Usefulness...

The present study emphasizes in situ transformation of soybean oil to self-assembled supramolecular multilayered biopolymer material. The said polymer material was characterized and the entrapment efficacy of both hydrophilic and hydrophobic moieties was studied. In brief, soybean oil at varying concentration was mixed with mineral medium and incubated under agitation (200 rpm) at 37 degrees C ...

A denoising unit based on wavelet multiresolution analysis is added ahead of the multilayered perceptron. The cost function used in neural network learning is also applied as the denoising criterion and hence denoising itself is treated as a part of the integrated model. By introducing continuously derivable generalized soft thresholding function and infinite thresholds, a gradient based learni...

This paper presents the input impedance measurement of a human body communication electrode by using newly developed multilayered phantom. Based on the comparison between analysis and measurement values, it was found that the multilayered phantom can be used for accurate evaluation.

The construction of multilayered films with tunable properties could offer new routes to produce biomaterials as a platform for 3D cell cultivation. In this study, multilayered films produced with five bilayers of chitosan and alginate (CHT/ALG) were built using water-soluble modified mesyl and tosyl–CHT via layer-by-layer (LbL) self-assembly. NMR results demonstrated the presences of mesyl (2....

A detailed in situ infrared spectroscopy analysis of single layer and multilayered graphene oxide (GO) thin films reveals that the normalized infrared absorption in the carbonyl region is substantially higher in multilayered GO upon mild annealing. These results highlight the fact that the reduction chemistry of multilayered GO is dramatically different from the single layer GO due to the prese...

Computed Tomography is a technique that can be performed using a set of X-ray images to re-create a three dimensional dataset which contains information about internal structure. Analysis of multilayered Printed Circuit Boards with their components using this technique allows for the non destructive evaluation of internal layers of failed boards. This report presents the results of computerised...

introduction: essential oils are used as flavoring agents in various foods. layer-by-layer (lbl) technique is a method in which the material is dipped into a series of different solutions containing oppositely charged polyelectrolytes. the aim of this study is to investigate the effectiveness of a multilayered edible coating with an antimicrobial compound (lemon and peppermint) in enhancing the...

Hybrid finite element (FE) boundary integral (BI) analysis of infinite periodic arrays is extended to include planar multilayered Green’s functions. In this manner, a portion of the volumetric dielectric region ci~n be modeled via the finite element method whereas uniform multilayered regions can be modeled using a multilayered Green’s function. As such, thick uniform substrates can be modeled ...
