Abstract Ultra-low-density BiFeO 3 nanoparticles have been prepared by pulsed laser deposition and their structure and magnetic properties have been studied. Annealing increases crystallinity and the size of the particles leading to an alteration of magnetic properties, observed from magnetic studies and evaluated usi…
The objective of this project was to evaluate the effects of increasing the initial in-place density of asphalt pavements on expected field performance and durability. This study was completed as part of the FHWA’s demonstration project on “Enhanced Durability through Increased In-Place Pavement Density.” Two approach…
Following the recent excitement in two-dimensional (2D) magnetism, we propose a yet-unexplored class of 2D ferromagnets derived out of Cr-based organic-inorganic layered compounds. Our density functional study in conjunction with model calculation establishes that assisted by the finite magnetocrystalline anisotropy,…
Herein, the filling of single‐walled carbon nanotubes (SWCNTs) with sulfur is performed, and the magnetic properties of the formed nanomaterials are studied. Encapsulation of sulfur species results in the appearance of a specific magnetic ordering in the system due to the formation of nanoscopic grains composed of sul…
Abstract Porous carbon microspheres (PCM) show bright application prospects in the fields of adsorption, supercapacitors, hydrogen storage, catalysis and sustained release. In this work, PCM were prepared by properly designed hydrothermal and activated processes using waste peanut shell as raw material. PCM maintained…
Organic single crystals of Benzilic Acid (BA) were grown by slow solvent evaporating method by using acetone as solvent. The unit cell parameter values and the crystal system are recognized by using single crystal XRD technique. The optical assessment of BA molecules is observed by with UV-Vis spectral analysis as the…
Flax fibres are of growing interest as a reinforcing fibre; however, they are susceptible to moisture and have demonstrated poor bond to conventional hydrophobic resins. Although there are multiple approaches to address these issues, research has heavily focused on their short-term performance. In this research progra…
Thermosensitive polymers enable externally controllable biomolecular interactions but hysteresis effects hamper the reversibility and repeated use of these materials. To quantify the temperature-dependent interactions and hysteresis effects, an optical adhesion assay based on poly(ethylene glycol) microgels (soft coll…
Effect of addition of cryogenic treatment to a standard heat treatment of aluminium alloy AW 7075 was tested in this work. Used heat treatment consisted of solution annealing at 470 °C for two hours and precipitation aging treatment at 130°C for 14 hours, 120 °C for 24 hours or natural aging at room temperature for 60…
Abstract The classical dipole model of partial discharge (PD) explains the relationship between the internal pulse charge and detected charge on the terminal, which is essential to assess the PD severity. However, the subsequent behavior (such as transport and dissipation) of the deposited charges generated during the…
Research study of volt-amperage properties (VAP) of [Formula: see text] crystals determined the mechanism of current flow though the studied samples and this mechanism is based on barrier Schottky emission and emission of Franklin–Paul. The dielectric constant of the material, height of the potential barrier on metal–…
Microbially influenced corrosion (MIC) is a common problem in biodiesel storage tanks. Here, thick microbial growths develop at and span aqueous/non-aqueous fluid interfaces. MIC in this setting was investigated in experiments using zero-resistance ammetry (ZRA) measurements. To mimic the water–fuel interface, one car…
In this study, light-responsive nano-assemblies with light-switchable size based on photoacids are presented. Anionic disulfonated napthol derivates and cationic dendrimer macroions are used as building blocks for electrostatic self-assembly. Nanoparticles are already formed under the exclusion of light as a result of…
Characterizing the morphology of polymeric foams is crucial for determining their practical applicability. The internal cellular structure of polymeric foams is typically analyzed by 2 D imaging techniques, such as Scanning Electron Microscopy (SEM) and optical microscopy. The problem with these techniques is that the…
Many parameters may influence the corrosion and the cathodic protection current demand in natural seawater. These are potential, temperature, dissolved oxygen content, biofilm and fouling activity, hydrostatic pressure, and calcareous deposit formation. In this study, the influence of the exposure depth on the corrosi…
In the past decades, the key roles of most microRNA in dermatosis and skin development have been explored one after another. Among them, microRNA-31 (miR-31) has a prominent role in the regulation of keratinocytes. Numerous studies show that miR-31 can positively regulate the proliferation, differentiation and cell ac…
The time-domain thermoreflectance (TDTR) technique has been widely used to measure thermal properties. The design and interpretation of the TDTR experiment rely on an in-depth understanding of the thermoreflectance signature for a given metal thermal transducer. Although the TDTR signals of several metal thermal trans…
The corrosion inhibition properties of methanol extract of Jatropha curcas (JC) were investigated for mild steel (MS) in acidic medium using weight loss and potentiodynamic methods. Corrosion inhibition of MS in 1MH2SO4 was studied in the absence and presence of various concentrations of the methanolic extract of Jatr…
Abstract The thermoluminescence (TL) mechanism for un-doped and europium (Eu 3+ ) doped barium aluminate (BaAl 2 O 4 ) were investigated and the location of energy levels for electrons/holes traps were determined in the aluminate for TL dosimetry applications. The solution combustion technique was used to synthesize t…
Abstract The surfactant properties of amphiphilic hyperbranched polyglycerols (HPGs) were investigated. The HPGs were prepared by ring-opening multibranching polymerization of glycidol using hydrophobic initiators of varying size and structure. The cloud points for all HPG surfactants were found to be >80 °C in deioni…
