Emergence of two-dimensional (2D) materials with atomic-layer structures, such as graphene and MoS 2 , which have excellent physical properties, provides the opportunity of substituting silicon-based micro/nanoelectronics. An important issue before large-scale applications is the heat dissipation performance of these materials, especially when they are supported on a substrate, as in most scena...

in this study, isophthalic acid-zirconium(iv) nanocomposite has been prepared from zirconyl nitrate pentahydrate and potassium iodide, with isophthalic acid, (c8h6o4=benzene-1,3-dicarboxylic acid) as a ligand, via sonochemical method in ethylene glycol and methanol as solvents. the crystalline tetragonal zro2 has been produced by thermal decomposition of isophthalic acid-zirconium(iv) nanocompo...

The reliability of microelectronic devices is largely dependent on electronic packaging, which includes heat removal. The appropriate packaging design therefore necessitates precise knowledge of the relevant material properties, including thermal resistance and thermal conductivity. Thin materials and high conductivity layers make their thermal characterization challenging. A steady state measu...

The present work deals with the synthesis and characterization of CdS nanoparticles with good thermal stability and optical properties by a novel and simple synthetic route. The nanoparticles were synthesized via chemical precipitation method in a single reaction vessel under ambient conditions. The prepared CdS nanoparticles were compared with the bulk CdS. The Optical properties were determin...

in this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-fha, ca10(po4)6(oh)2−xfx) nanopowders. the advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. calcium nitrate tetrahydrate, phosphorous pentoxide and tetrabuthylammonium fluoride were used, respectively, as p, ca, and f p...

Rosin has a comprehensive application in adhesives, printing inks, protective coatings, rubbers and pharmaceutical. In this work, novel dual UV/thermal curable epoxy rosinate was synthesized by esterification reaction between epoxy resin and purified rosin. This product was evaluated by FT-IR spectroscopy techniques and acid number. UV curable resin was formulated for UV curing ability by benzo...

As semiconductor devices continuously get both smaller and faster, a profound analysis of the dynamic (time-dependent) thermal behaviour is becoming more and more important. In this article some basic concepts and numerical methods for thermal characterization in the frequency domain are explained. Two practical examples are given. First a simple model is presented for a small package mounted o...
