In several research fields, the properties at the interphase between two materials in contact can be quantified by the degree of adhesion. Previous research indicated that a rigorous prediction of the quality of cooperation between biomaterial substrate and human component (cells/tissue) can be achieved though analytical models. In the present investigation, an established theory related to the interphase adhesion in composite materials has been used to redefine the adhesion process of human tissue to a substrate and furthermore, to analyze the type of cooperation between them. Through the present investigation it is shown that modeling-based design of biomaterials can enable the optimum feedback of the human component. Thus, the aim of the present study is to interconnect elements of material science, mechanics and biology in a common theory on the analytical modeling at the interphase between inert materials and human cells/ tissues and further on, to develop a strategy of programmed biomaterial design based on modeling output and property prediction. It has been concluded that phenomena at the interphase decide for the implant integration in the host body.In several research fields, the properties at the interphase between two materials in contact can be quantified by the degree of adhesion.

This paper reports on the synthesis and physical properties of conducting composites based on polyaniline and polystyrene. Polyaniline composite powders are synthesized by oxidative polymerization in an acidic medium. Thermal properties are characterized by thermo gravimetric analysis and differential scanning calorimetry. UV-Visible absorption spectroscopy is also used to study the optical properties of the deposited films. The optical gap decreases from 4.6 eV to 2.7 eV with increasing polyaniline content from 0.5 to 5 wt. % confirming the improvement of the semi-conductive properties. Due to the absorption properties in near infrared of the thin composite layers they can be promising materials for optoelectronic and photovoltaic applications.This paper reports on the synthesis and physical properties of conducting composites based on polyaniline and polystyrene.

In this communication, a methodological approach based on the combination of the state space method and the differential quadrature method (SS-DQM) is used to analyze the static and dynamic behavior of magneto-electro-elastic rectangular plates with viscoelastic interfaces based on a Winkler-Pasternak elastic support and with different boundary conditions. The state space method is used to estimate the solution in the thickness direction with an arbitrary number and different types of layers, whereas the DQM method is used to take into account all the boundary conditions. Afterward, to convert the obtain solutions from Laplace domain to temporary one we use the inverse Laplace transform.In this communication, a methodological approach based on the combination of the state space method and the differential quadrature method (SS-DQM) is used to analyze the static and dynamic behavior of magneto-electro-elastic rectangular plates with viscoelastic interfaces based on a Winkler-Pasternak elastic support and with different boundary conditions.

The aim of this work was to establish the effect of environmental factors (moisture and temperature) on some mechanical, electrical and thermal properties of epoxy-based composites filled with carbon nanofillers: nanotubes (CNT), nanofibers (CNF) and hybrid nanofiller (nanotubes/nanofibers in the ratio 1:1) and to reveal the most environmentally stable NC. First, the nanocomposites (NC) containing different nanofiller contents were prepared to evaluate electrical percolation threshold and to choose NC at certain electrical conductivity for further characterization of the physical properties in initial state and during/after environmental ageing. The environmental ageing consisted of water absorption at 70 °C until equilibrium moisture content reached all samples in 4 weeks and 2) heating at 70 °C for the same time, and 3) freezing at -20 °C for 8 weeks. Two concurrent factors, temperature and moisture, led to post-curing of all materials studied without significant plastization. Some positive nanofiller effects were found for sorption, mechanical and thermophysical characteristics of RTM6 epoxy resin. Based on experimental results, the most environmentally stable NC was epoxy filled with 0.1 wt. % of CNT/CNF hybrid, which had the lowest effect of temperature and moisture on thermal and electrical conductivities, along with the lowest equilibrium water content and diffusivity.The aim of this work was to establish the effect of environmental factors (moisture and temperature) on some mechanical, electrical and thermal properties of epoxy-based composites filled with carbon nanofillers: nanotubes (CNT), nanofibers (CNF) and hybrid nanofiller (nanotubes/nanofibers in the ratio 1:1) and to reveal the most environmentally stable NC.
