Alcohol soluble titanium chelate TIPD (titanium (diisopropoxide) bis(2,4-pentanedionate)) was used as electron transporting layer to form an ohmic contact with the negative electrode, aiming to enhance the charge extraction and suppress the charge recombination for high performance CH3NH3PbI3/PCBM-based PHJ perovskite…
Research of the protective diamond-like carbon coatings by means of IR-spectral ellipsometry method and Raman spectroscopy method were carried out. Diamond-like carbon coefficients, optical constants, specific electric resistances and thicknesses of diamond-like carbon coatings were determined. Research of the mass lo…
The formation of martensite is characterized by its athermal transformation kinetics, crystallographic features, and development of fine structure. This chapter describes the diffusionless, shear-type transformation of austenite to martensite and how it affects the morphology and microstructure of heat-treatable carbo…
Zementgebundene Hochleistungsfaserverbundwerkstoffe (engl. High Performance Fiber Reinforced Cement Composites, HPFRCC) stellen eine Klasse von Zementkompositen dar, die dehnungsverfestigend sind, eine hohe Bruchdehnung aufweisen und vor Erreichen der Höchstlast zahlreiche Risse zeigen. Neben dieser mechanischen Defin…
This perspective examines the institutional and technical obstacles to the commercialization of advanced nuclear reactors for electrical power generation in the United States, evaluation of non--light-water reactor nuclear plants, and investing the time and resources needed to establish the operational and safety char…
Combining functions of multidrug co-delivery and multistep release in biocompatible membranes is an oncoming requirement for improving therapeutic process. In this paper, a kind of polymer micelle-embedded core/shell nanofibrous membranes was prepared by a simple and effective technology of coaxial electrospinning. Th…
This chapter describes the ferritic microstructures that form in carbon steels under continuous cooling conditions. It begins with a review of the Dubé classification system for crystal morphologies. It then explains how cooling-rate-induced changes involving carbon atom diffusion and the associated rearrangement of i…

Organic thin film solar cells are potential ‘next generation ’ solar cells. Many p-type semiconductors have been used in organic solar cells, but there have been far fewer reports involving n-type organic semiconductors. Developing new n-type organic semiconductors is therefore desirable. Decaphenylpentasilane (DPPS)…
ABSTRACTMagnesium silicide is a promising eco-friendly thermoelectric material. Its constituent elements are non-toxic and exist in abundance on the earth. To improve thermoelectric performance of the material, reduction of thermal conductivity is required. In this study, we attempted to lower the thermal conductivity…
The aim of this study is to investigate the effect of work material variations on machinability. Improved knowledge in this respect supports the development of sustainable production both from resource and economical points of view.The properties of work materials vary greatly depending on how they were manufactured.…
Two-step aging behavior of an Al–10%Si–0.3%Mg alloy cast into permanent mold, rolled up to 68% and solution-treated was investigated by micro-vickers hardness measurement and transmission electron microscopy (TEM). In the case that final-aging temperature is relatively lower and the holding time in iced water is longe…
An analytic technique based on spectral plane wave representation of fields (SPRF) for the scattering of a plane wave from a perfectly electric conductor (PEC) cylinder coated with double positive (DPS) or double negative(DNG) materials buried beneath a slightly rough surface is formulated. Small Perturbation Method i…
A one-dimensional finite difference method allowing for anisotropic deformation is used in conjunction with a nonlinear thermoelastic-viscoplastic material model to compute the shock response of various microstructural instantiations of pure aluminum at peak stresses exceeding the Hugoniot Elastic Limit (HEL). Single…
In modern steelmaking, carburizing steels are often used for production of automotive components with elevated levels of toughness and fatigue strength. This study is focused on the link between the characteristics of non-metallic inclusions in the steel and the machinability of the given steel grades. For this purpos…
An optical spike is sometimes observed prior to the main flash in high-velocity impact experiments. The spikes are particularly noticeable in the case of Nylon66 projectiles. In this study, we conducted experiments in which Nylon66 spheres impacted the flat surfaces of Nylon66 blocks perpendicularly at 7 km s-1. We ob…
Production of extremely efficient flame retardants is ideal because, in many instances, the amount of flame retardants that are added to pre-production to the mixture are so large that they can have an effect on the physical properties of the material. In addition, these types of polymers, when added during production…
Fish collagen is known to have good moisturising property and antioxidant ability, which has been increasingly added into cosmetics, foods and drinks as thicker agent and to increase dietary supply of collagen. Fish collagen peptide (FCP) is a white or pale yellow powder, obtained by extracting collagen from sources i…
This paper describes a series of tests conducted at VTT Technical Research Centre (Finland) in order to assess the influence of pre-stressing on perforation capacity of concrete slabs under hard missile impact (impact with negligible missile deformations).The paper presents three tests along with their results having…
