Effect of Fiber Modification on Pineapple Leaf Fiber's Mechanical Properties and Interfacial Adhesion
Authors : Haydar U. Zaman,Ruhul A. Khan,


Due to their key benefits, which include having a moderate strength and stiffness, being inexpensive, and being a material that is good for the environment, degradable, and renewable, natural fibers are seen as having potential application as reinforcing agents in polymer composite materials. Because of their natural hydrophilicity, they are prone to absorbing moisture, which can weaken or...

Changing of Transport of Charge Carriers in an Implanted-junction Heterorectifier under the influence of Mismatch-induced Stress
Authors : E.L. Pankratov,


In this paper we analyzed changing of charge carrier’s mobility in an implanted-junction heterorectifier under the influence of mismatch-induced stress. We introduce a model to describe the above changing of the mobility. Analysis of the above model leads to conditions (i) to change of the above mobility under influence of the considered stress; (ii) to change of mismatch- induced stress...

Applying Graph Theory and Multi-Variables G-Function to Solved the Problem Related to Cooling a Sphere
Authors : Gurusharan Kaur,Pinkey Sikarwar,Amrita Dwivedi,Laxmi Rathour,


We have observed that the separation of variables method and graph theory in mathematics can be applied to several types of problems on bounded three-dimensional domains. The problem must be linear and have homogeneous boundary-conditions. In this paper, we present the result of classical problem in three dimensions by applying modified integral form, of Newton's law of cooling for sphere, which...

A Review on Polymer Nanocomposites and Its Applications
Authors : Haydar U. Zaman,Ruhul A. Khan,


Multiple phases that have at least one, two, or three dimensions in the nanoscale range make up a nanocomposite material. Phase interfaces are produced when material dimensions are reduced to the nanoscale level, and they are crucial for improving the properties of the material. Understanding the relationship between structure and property is directly influenced by the surface area to volume...
