[en] Full text:The copolymerization reaction of ρ-(substituted) cyclopropyl styrene's with styrene has been studied. An influence of substituent's on reactivity of ρ-(substituted) cyclopropyl styrene's has been investigated. The copolymerization constant values and Q-e parameters of Alfrey-Praice scheme have been calculated. The parameters of microstructure of copolymers have been determined

[en] Methods for estimating the parameters of relief – phase diffraction microstructures (local and integral Q-factors) are extended to the case of multilayer double-relief sawtooth microstructures, which makes it possible to select the best combinations of optical materials for multilayer microstructures at a very low computational burden. An approach to the study of multilayer microstructures is proposed, based on the combined use of Q-factors and the method of rigorous analysis of coupled waves, which allows one to estimate the limiting spectral and angular characteristics of multilayer microstructures of various types.

[en] The purpose of the current work is to analyse the effect of tilt angle and tool hardness on mechanical and microstructural characteristics of FSWed Al-Mg4.2 joints. The joints were fabricated varying the tilt angle and tool hardness at six different levels each, keeping other FSW parameters constant. Microstructure, macrostructure, strength and hardness characteristic of the welds has been sifted in order to understand the sensitivity of studied input variables on the joints quality. The outcome of the present investigation clearly indicates that the tilt angle and tool hardness notably affects the performance parameters of the FSWed joints. The paper suggests that 1°−3° tilt angle and 40–50 HRC tool hardness produces sound quality joints. The present work dredges a novel look on FSWed Al-Mg4.2 joints by dint of relating the macrostructure, microstructure and fractographs with the plasticized material movement in the process. (paper)

[en] In combining biomechanical investigations with microanatomical studies, the authors have found new evidence suggesting a mechanobiological link between the altered microstructural response of degenerate cartilage to load, and the way in which structural changes develop in the early osteoarthritic joint. This paper presents the data and background for a new hypothesis exploring the initiation and progression of mechanically-driven osteoarthritic processes.

[en] In this work we examine a Faraday magnetometer built for microstructure analysis. We single out sources of error and quantitatively evaluate their effect on the measurement process. From this we derive a generalised estimation concerning temporal, spatial and amplitude resolution. We point out where the examined setup can be improved, but also where the limits of feasibility of a Faraday magnetometer as a means of measuring magnetic microstructures lie. (paper)

[en] We summarize recent advances in modeling of solidification microstructures using computational methods that bridge atomistic to continuum scales. We first discuss progress in atomistic modeling of equilibrium and non-equilibrium solid-liquid interface properties influencing microstructure formation, as well as interface coalescence phenomena influencing the late stages of solidification. The latter is relevant in the context of hot tearing reviewed in the article by M. Rappaz in this issue. We then discuss progress to model microstructures on a continuum scale using phase-field methods. We focus on selected examples in which modeling of 3D cellular and dendritic microstructures has been directly linked to experimental observations. Finally, we discuss a recently introduced coarse-grained dendritic needle network approach to simulate the formation of well-developed dendritic microstructures. The approach reliably bridges the well-separated scales traditionally simulated by phase-field and grain structure models, hence opening new avenues for quantitative modeling of complex intra- and inter-grain dynamical interactions on a grain scale
