ABSTRACT: In this paper, thermo optical properties of homologous series of hydrogen bonded liquid crystals: p-n alkyl benzoic acid (nBA): heptyl p hydroxybenzoate (7HB) (where n=5 to 10) have been investigated by means of applying Image analysis technique in conjunction with Polarizing Optical Microscope. Textures of liquid crystal complexes are captured. The changes in textural features as a f...

Thermo-mechanical densification modifies wood to produce a more dense and resistant lignocellulosic material may degrade extractives that contribute the increased susceptibility of attack by xylophagous organisms. This study evaluated efficiency tannin extracts Acacia mearnsii in treatment thermo-mechanical densified pine relation physical, mechanical, biological resistance (Cryptotermes brevis...

This note deals with concrete applications of the general treatment of anisotropic thermo-elasticity developed in the first part [M. Reissig, J. Wirth, Anisotropic thermo-elasticity in 2D A unified treatment, Asympt. Anal. ?? (????) ??–??]. We give dispersive decay rates for solutions to the type-1 system of thermo-elasticity for certain types of anisotropic media. 1. Elastic operators and ther...

Gelatin films were prepared by casting. Tensile strength (TS) and elongation at break (Eb) of the gelatin films were found to be 46 MPa and 3.5%, respectively. Effect of gamma radiation (Co-60) on the thermo-mechanical properties of the gelatin films was studied. 2-hydroxyethyl methacrylate (HEMA) was added to the gelatin during casting varying (10% 30% by weight) and found to increase the TS s...

Nanowires (NWs) exhibit thermo-mechanical properties that are distinct from their bulk properties, and their understanding is critical for the reliability, manufacturability, and optimization of a wide range of devices consisting of NWs. Here, molecular-dynamics simulation reveals a rich size-temperature “phase diagram” for the mechanical response of a zinc-oxide NW under tension. For smaller d...

Currently, the mass parts production all over the world becomes more and more individual. It is required to be able to manufacture personalized complex shape parts with necessary microstructural, mechanical, thermo-physical, chemical and other properties in a quicker and a cheaper way. Selective Laser Sintering /Melting, a process of Additive manufacturing technologies, is applied to answer on ...

Steady, continuum, laminar plasma flow over spheroidal particles has been numerically investigated in this paper using a finite volume method. To body-fit the non-spherical particle surface, an adaptive orthogonal grid is generated. The flow field and the temperature distribution are calculated for oblate and prolate particle shapes. A number of particle surface temperatures and far field tempe...

There are many techniques available to study physical properties to interpret the molecular interaction in liquids, liquid mixtures and solutions. The study of ultrasonic waves through solution is found to be quite interesting. The study of ultrasonic waves through solution is used for knowing the nature and strength of intermolecular forces and their interaction in liquids, liquid mixtures and...

In this study, we demonstrate an effective approach based on a simple processing method to improve the thermomechanical properties of graphene polymer composites (GPCs). Edge-selectively functionalized graphene (EFG) was successfully obtained through simple ball milling of natural graphite in the presence of dry ice, which acted as the source of carboxyl functional groups that were attached to ...

The microstructural and mechanical properties of Laser Based Additive Manufacturing (LBAM) are still inconsistent and unreliable, which is a major barrier that prevents Additive Manufacturing (AM) from entering main stream production. The key challenge is the lack of understanding for the underlying process-properties relationship. We monitor Laser Engineered Net Shaped (LENS) process using a s...
