A typical plain carbon eutectoid steel (without addition of any significant alloying element) is developed possessing notably high strength (UTS = 2016 MPa) and reasonable ductility (%Elongation = 11) with an application of typical cyclic heat treatment that involves a combination of reconstructive and displacive tran…
Thermally sprayed WC-Co-VC coatings are widely used based on their resistance to abrasive wear. This chapter shows the fabrication procedure of bimodal WC-Co-VC coatings applied by a high-velocity oxy-fuel (HVOF) thermal spray process. We analyzed the effects of the mixture content of the nanostructure and microstruct…
Surface texturing as a means for controlling tribological properties of mechanical components is well known for many years. Various technologies have been developed for surface texturing. Among them, ultrashort pulsed laser surface texturing is one of the most promising ways to achieve micromachining in the field of t…
Abstract The equilibrium form of carbon in iron and steel is graphite. In higher carbon cast irons graphite is normally formed from the liquid state. In lower carbon steels, carbon invariably exists in the form of metastable cementite, due to slow graphitization kinetics in the solid, but in fact, graphite formation i…
Abstract Results of numerical calculations of heat exchange in a nuclear heating detector for nuclear reactors are presented in this paper. The gamma radiation is generated in nuclear reactor during fission and radiative capture reactions as well as radioactive decay of its products. A single-cell calorimeter has been…

During normal ITER operation, Electron Cyclotron (EC) heating and current-drive system will generate stray microwave radiations. Three cases have been identified with their associated load localisation and power. The effect on first-wall diagnostics, mineral insulated cables and vacuum windows are described. The most…
Femtosecond two-pulse correlation spectroscopy, temperature program desorption spectroscopy, and density functional theory calculations are used to elucidate the mechanisms and the ultrafast dynamics of carbon monoxide (CO) oxidation reaction on palladium nanoparticle (Pd NP) surfaces. Two different time scales for th…
Abstract Some aspects of the evolution of structural chemistry are described from the personal perspective of a student of Jack Dunitz who started working for a Ph.D. in crystal chemistry in the mid‐1960s. The importance and the change of emphasis of X‐ray crystal structure determination through the decades is sketche…
Over the past years, there has been significant interest in the study of nanoparticles for clinical applications, particularly quantum dots (QDs). However, previous studies have also shown that QDs can reach the embryo through the placenta, a natural barrier for a large variety of organic substances with diverse molec…
By the chemical cross-linking of rigid molecules, liquid crystal polymer (LCP) has been envisaged as a novel heterogeneous material due to the fact that various optical and geometric states of the liquid crystalline (LC) phases are projected onto the polymeric constituents. The phase behavior, which refers to the macr…
A 100-nm wide, vertically formed graphene stripe (GS) is demonstrated for three-dimensional (3D) electronic applications. The GS forms along the sidewall of a thin nickel film. It is possible to further scale down the GS width by engineering the deposited thickness of the atomic layer deposition (ALD) Ni film. Unlike…
Insufficient angiogenesis in severe wounds delays wound repair because of a lack of blood supply to the wound site. Therefore, pro-angiogenic therapeutics may enhance wound repair. Many studies have investigated various physical and biochemical cues to improve angiogenesis, such as biocompatible materials, surface mod…
ABSTRACT Molecular imprinting process was proposed for the sulfur removal from fuels. The novel network‐structured molecularly imprinted polymers (MIPs) were fabricated by arranging 4‐vinyl pyridine functional monomers around dibenzothiophene template compounds, and fixing them with ethylene glycol dimethacrylate as c…
Transmitting power by extra-high voltage and ultra-high voltage systems becomes obligatory with the rapid increase in power demand by industrialization and urbanization. Insulators in the transmission system play a significant role in maintaining the reliability of the network by providing the required mechanical supp…
The Influence of plasma sprayed NiCr–Cr2O3 and Al2O3–40% TiO2 (A40T) coatings on Inconel 617 are investigated at 900 and 1000 °C under mixed salt environment for gas turbine applications. The results revealed that the plasma coated alloy exhibits lower mass change than bare alloy in the Na2SO4 and NaCl salt mixture wi…
The effect of different sample structures of an iron-tungsten model system (as a surrogate for reduced activation ferritic martensitic steels like EUROFER) on the development of surface morphologies, tungsten surface enrichment and sputter yields under low-energy monoenergetic perpendicular 200 eV deuterium bombardmen…
Herein, the formation of hollow microballoons derived from superparamagnetic iron oxide nanoparticles with silica patches is reported. Depending on the experimental conditions, single- or multishelled superparamagnetic microballoons as well as multivesicular structures were obtained. We show how such structural change…
A widely used method for hot forming steels and alloys, especially heavy forging, is the process of multistage forging with pauses between stages. The well-known effect which accompanies multistage hot forging is metal plasticity recovery in comparison with monotonic deformation. A method which takes into consideratio…
This focused review provides an overview and a framework for understanding local structure in metallic plutonium (especially the metastable fcc -phase alloyed with Ga) as it relates to self-irradiation damage. Of particular concern is the challenge of understanding self-irradiation damage in plutonium-bearing material…
