This research focus on the characterization of banana and abaca reinforced composites obtained by rotational molding process. These composites were fully characterized by means of DSC and mechanical tests (tensile, flexural, impact and DMA), as well as by optical microscopy. Tests presented in this paper aim to the ob…
The corrosion environments of individual parts of members in a steel structure vary significantly. Therefore, efficient maintenance requires accurately evaluating these environments and predicting corrosion damage over time. This research focused on comprehensively evaluating the corrosive environment of each part of…
To improve the wear resistance of brass substrate while retaining the electrical conductivity, laser cladding was applied to Cu-WC-Ni composite coating on brass using High Power Diode Laser. Microstructures, phase constitution and wear properties are investigated by means of scanning electronic microscopy with energy…
Cross-sectional deformation of multiwalled carbon nanotubes under isotropic radial pressure is investigated in a realm of continuum elastic approximation. The nanotube we assumed is subjected to the embedment into an elastic medium and stiffener insertion into the core cavity. Combination of the two reinforcement mani…
Antiferromagnetic (AFM) order and a spatial order peculiar to Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states, previously indicated in the quasi-two-dimensional $d$-wave superconductors CeCoIn${}_{5}$ with strong paramagnetic pair breaking (PPB) in a magnetic field parallel to the basal plane, are considered in the fie…
In this article, the evaporation of niobium, ruthenium, and titanium using a conventional mini electron-beam evaporator (Tectraé-flux) is described. These metals require high temperatures for evaporation due to their high melting points, low vapor pressures, and large bond energies between atoms. Usually, a high-power…
Abstract AgGaTe2 layers were grown on a‐plane sapphire substrates by a closed space sublimation method. Various samples were prepared with varied source temperature, holding time and temperature differential. The variation of source temperature was used primarily to improve the stoichiometry of the film. Grown films w…
Interactions between the polyamidoamine (PAMAM) dendrimer and drug molecules are of interest for their potential biomedical applications. The goal of this work is to examine the interaction of PAMAM-C12 25% dendrimer with morin. The ultraviolet-visible, fluorescence spectroscopic methods as well as molecular modeling…
Abstract We study the electronic properties of hydrogenated carbon nanotubes under an electric field based on the density functional theory with effective screening medium method. We find that, screening against the external electric field strongly depends on local atomic arrangement due to the inhomogeneous charge di…
Volume is indexed by Thomson Reuters CPCI-S (WoS).The book covers a wide range of topics: Fracture Mechanics, Failure analysis, Composites, Multiscale Modelling, Micromechanics, Structural Health Monitoring, Damage Tolerance, Corrosion, Creep, Non-linear problems, Dynamic Fracture, Residual Stress, Environmental effec…
Freezing and thawing cycles in northern regions lead to serious deterioration in bridges and dictate the need for early repair or replacement. The use of polyvinyl alcohol (PVA) fibers in cementitious composites improves durability because of their ability to withstand large deformations due to its strain-hardening an…
Mechanical and viscoelastic behavior of cement crucially depends on the Calcium-Silicate-Hydrate (C-S-H) gels, the "glue" of cement, and on the slow evolution (aging) of its local composition and morphology. Hence, design of high performance and more environmentally friendly cement demands a deeper understanding of ph…
This work is focused on the chemo-mechanical characterization of cement-based materials. A novel approach is presented which combines the classical grid indentation technique with x-ray energy dispersive microanalysis method. Two oil-well cement systems with different combination of silicious filler are examined, both…
A synergism between methyl methacrylate and an amphiphilic ionic liquid acrylate 1-(11-acryloyloxyundecyl)-3-methyl imidazolium bromide (IL) not only increases the apparent thermal stability (kinetic retardation of thermal decomposition) of poly(MMA- co -IL) copolymers by 50 °C at relatively low doping levels of 0.5 m…
Ultrasonic Corrosion Fatigue Tests were Conducted for SUS329J3L in Air and 3%NaCl Aqueous Solution. Reduction of Giga-Cycle Corrosion Fatigue Strength was 12.5%. Corrosion Pit was Observed on Corrosion Fatigue Crack Initiation Area. Striation was Predominantly Observed on Crack Propagation Area both in Air and 3% Nacl…
We analyze the evolution of nanoscale order in amorphous GexSe1−x alloys using fluctuation electron microscopy. We identify two distinct structural signatures that behave independently as a function of composition. The strong signature of order at scattering vectors k ∼ 0.30 and 0.55 Å−1 in Ge-rich alloys (x > 0.40) d…
Analysis on the aspects of the energy dissipation in the case of quasi-brittle fracture is presented. Dissipation both via cohesive forces at the crack faces and the one taking place within the volume of the fracture process zone is considered. Tools from the field of soft computing techniques are employed. The analys…
Abstract The chemical composition and morphology of pulp fibers have a significant impact on the properties of fiber products. Pulp samples from a novel unique Eucalyptus triple hybrid [Eucalyptus grandis × (Eucalyptus urophylla × Eucalyptus globulus)] were obtained by various pulping processes – kraft, soda-anthraqui…
The paper presents the results of fatigue crack growth rate test of iron sinters. The samples were produced by means of the impact sintering. Applied production method allowed to obtain dense sinters with fine grain size resulted from large shear strains. Due to the limited size of the final products the mechanical te…
Abstract Augmentation of myocardial tissue regeneration processes in injured hearts represents a major challenge in cardiology as current therapeutic approaches do not regenerate the myocardial tissue. Herein, we describe three emerging biomaterial‐based strategies to treat heart injuries, as stand‐alone therapies or…
