The ferrocene/Poly(vinyl pyrrolidone) (PVP) composite membranes have been successfully prepared by using electrospinning and polarization coating techniques, respectively. The composite membranes were characterized by means of SEM (scanning electron microscopy), UV-vis absorption spectra, FT-IR (Fourier transform infrared), XRD (X-ray diffraction) and a radio frequency (RF) impedance/capacitanc...

Cold spray coatings are considered promising for surface protection of light metal substrates but the mechanisms of bonding and coating build-up are still poorly understood and are the subject of continuing debate. A variety of coating/substrate combinations have been characterised in detail using electron microscopy to examine the nature of the interparticle and particle/substrate interfaces. ...

Coating and lamination are two functional processes which are used make a proper finishing to the textile material. The coating formulation with different textile grade polymer like PVC, PU, acrylic, PTFE are hugely used to make a textile product with multipurpose way likewaterproof protective clothing, tarpaulin, protective clothing, electrical insulation etc. on the other hand lamination proc...

Abstract— Non Destructive Evaluation (NDE) is the method of evaluating material or object without to damage or make worse. This method is used in process and quality controls and it is also used to evaluate of aircraft, power plants, turbines, nuclear reactor. Electro thermal model is used to find the defects in metals, semiconductor and composite materials etc. till now research has not been t...

Metallic coatings are primarily designed to enhance properties have been ascertained via indentation, this method can also serve as a non-destructive quality surface properties such as corrosion resistance, thermal protection, and tribological behaviour of a particular control test during production. In the present work experimental and computational studies of microand component in service. Ho...

!BSTRACT The presented paper demonstrates a method to embed a unique signature into a coating material used in a smart card or in the covering material of some other secure hardware device. The method bases on the impossibility of exactly reproducing a specific piece of plastic or other material used to cover the secure hardware. By using a very inhomogeneous materials or mixtures of conductors...

This study aims to validate, using finite element analysis (FEA), the design concept by comparing the fatigue behavior of hip implant stems coated with composite (carbon/PEEK) and polymeric (PEEK) coating materials corresponding to different human activities: standing up, normal walking and climbing stairs under dynamic loadings to find out which of all these models have a better performance in...

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...

To reduce critical dimension (CD) variation due to multiple interference effect, anti-reflective coatingl) and over coating processes2) have been proposed and investigated. In this paper, we discuss the problem of the over coating processes and report a new and simple process, called OCT (Optical-path Control Technique), for reducing the multiple interference effect that does not require new ma...
