With the recent advances in nanoscience and nanotechnology, more and more nanoparticle catalysts featuring high accessibility of active sites and high surface area have been explored for their use in various chemical transformations, and their rise in popularity among the catalysis community has been unprecedented. Th…
Sulfate-reducing bacteria (SRB) are known as potential promoters for microbiologically influenced corrosion (MIC). Many researchers have studied the SRB-induced corrosion in the presence of organic nutrients. However, SRB-metabolizable organics are not constantly present in corroding environments. In this study, pitti…
The combination of two or more seemingly distinct properties into a unique composite is an exciting direction for the fabrication of novel multifunctional materials. A vacuum-filtration method was used to fabricate strong and multifunctional heparin/layered double hydroxide (HEP/LDH) films mimicking nacre. The experim…
This article describes the physico-geometrical mechanism and overall kinetics for the carbonation of lithium hydroxide monohydrate (LHMH). The constituent reactions of thermal dehydration of LHMH and carbonation of as-produced anhydrous lithium hydroxide (LH) were investigated using thermogravimetry and morphological…
Spin polarization induced by an external electric field in graphene is considered theoretically in the linear-response regime. The graphene is assumed to be deposited on a substrate which leads to the spin-orbit interaction of Rashba type. The induced spin polarization is shown to be in the graphene plane and perpendi…
Self-assembly of small peptide derivatives affords supramolecular nanofibrils that possess characteristic features of amyloid oligomers. Acting as de novo amyloid oligomers, the nanofibrils effectively inhibit the tumor progression both in vitro and in vivo, which demonstrates a new type of anticancer approach and may…
We present a three-dimensional constitutive model for NiTi polycrystalline shape memory alloys exhibiting transformations between three solid phases (austenite, R-phase, martensite). The ‘full modelling sequence’ comprised of formulation of modelling assumptions, construction of the model, mathematical analysis and nu…
Two new barium borate fluorides LiBa12(BO3)7F4 and NaBa12(BO3)7F4 are obtained by spontaneous crystallization from high-temperature flux. The two compounds are isostructural and crystallized into the tetragonal system, I4/mcm space group, with unit cell parameters of a = 13.5709(6) Å, c = 14.9908(13) Å for LiBa12(BO3)…
Peripheral nerve regeneration can be enhanced by chemical and mechanical cues for neurite growth. Aligned and randomly oriented electrospun nanofibers of poly(ε-caprolactone) (PCL) or a blend of PCL and elastin were fabricated to test their potential to provide contact guidance to embryonic chick dorsal root ganglia f…
Delivery systems designed to have triggered release after passively targeting the tumor may improve small molecule chemotherapeutic delivery. Particle replication in nonwetting templates was used to prepare nanoparticles to passively target solid tumors in an A549 subcutaneous xenograft model. An acid labile prodrug w…
Production of Anti-Corrosion Coatings on Light Alloys (Al, Mg, Ti) by Plasma-Electrolytic Oxidation (PEO)
ABSTRACT The super hydrophobic, self‐cleaning properties of natural species derive from the fine hierarchical topography evolved on their surfaces. Hierarchical architectures which are function‐mimetic of the lotus leaf are here described and created from multi‐scale hierarchical assembled templates. The first level o…
Abstract With the goal to obtain a molecularly defined iridium(I) heterogeneous CH functionalization catalyst, a periodic mesoporous organosilica (PMO) containing bipyridylene moieties in a matrix of biphenylene units as ligand platform was designed and fully characterized. The material exhibits a high surface area w…
Zinc phosphide may have potential for photovoltaic applications due to its high absorptivity of visible light and the earth abundance of its constituent elements. Two different solution-phase synthetic strategies for phase-pure and crystalline Zn 3 P 2 nanoparticles (∼3–15 nm) are described here using dimethylzinc and…
Corrosion behavior of zinc exposed to a tropical marine atmosphere for 4 years was investigated. The results showed an obvious decrease in the corrosion rate, which was attributed to the development of the protective corrosion product layer with one element of this structure being simonkolleite (Zn5Cl2[OH]8·H2O). Corr…
We report structural and magnetic properties of rare earth doped Bi0.95R0.05 FeO3 (R = Y, Ho, and Er) submicron particles. Rare earth doping enhances the magnetization and the magnetization shows an increasing trend with decreasing dopant ionic radii. In contrast to the x-ray diffraction pattern, we have seen a strong…
Dendron brushes are molecular structures built up of treelike macromolecules, with multiple generations of branches, grafted with a root segment to a surface (particle) or to a backbone chain (dendronized polymer) with a sufficiently high grafting density so that the dendrons interact laterally. Recent advances in the…
A biomaterial inhibits the host immune response by displaying an endo-genously expressed immunomodulatory molecule, CD200. Immobilization of CD200 onto biomaterial surfaces effectively suppresses macrophage activation and reduces inflammatory response to subcutaneously implanted materials.
As part of a factory acceptance test program for high-voltage (HV) motors, end users sometimes specify a black-out test. This is a traditional offline inspection where the stator is placed in complete darkness, each phase is energized to 115% of rated line-to-neutral voltage, and both ends of the stator are observed t…
Magnetite nanoparticles were prepared by co-precipitation method and then silica was coated onto the surface of <TEX>$Fe_3O_4$</TEX> by hydrolysis of TEOS. The silica coated magnetite nanoparticles were characterized for its structural, microstructural, optical, vibrational and magnetic properties by X-ray diffraction…
