Synthetic polymers composed of metabolites endogenous to the mammalian organism are designed. The design is based on the monomer xylitol, which possesses a wide range of physical properties that are biologically relevant. Xylitol-based hydrogels and elastomers are biocompatible in vitro and in vivo, compared to the pr…
If you need a book that relates the core principles of quantum mechanics to modern applications in engineering, physics, and nanotechnology, this is it. Students will appreciate the book's applied emphasis, which illustrates theoretical concepts with examples of nanostructured materials, optics, and semiconductor devi…
Homogeneous alloy nanoparticles as excellent catalysts. Spherical polyelectrolyte brushes can be used to generate Au-Pt alloy nanoparticles (see figure) that exhibit properties widely differing from the properties of the respective bulk alloys. The alloy nanoparticles are shown to be homogeneous solid solutions. Moreo…
Anions included: A series of meso-tetraaryl calix[4]pyrrole receptors have been used as a model system to quantify chloride–π interactions in solution (see picture; green balls are chloride ions). The free energy values are generally indicative of a repulsive interaction; their magnitude depends on the substituent on…
Silicon nanowires (SiNWs) arrays prepared by electroless etching show excellent optical antireflectivity over a wide spectral bandwidth from 300to1000nm and surface defect-induced electrical conductivity. Both characteristics make the SiNWs a promising material for photovoltaic cell applications. Photoelectrochemical…
Tissue-engineered skin has been in clinical use for 25 years and has developed greatly during this time. This review looks at the role biomaterials need to play in providing for epidermal cover, dermal replacement, and epidermal/dermal replacement, and describes the major problems that remain. The majority of biomater…
We investigate the application of embedded atom method (EAM) interatomic potentials in the study of crystallization kinetics from deeply undercooled melts, focusing on the fcc metals Al and Cu. For this application, it is important that the EAM potential accurately reproduces melting properties and liquid structure, i…
Abstract A peak fitting procedure has been implemented for calculating crystallinity in granular starches. This methodology, widely used for synthetic polymers, is proposed to better reflect the crystalline content of starches than the method normally used, in which it is assumed that relatively perfect crystalline do…
Materials that enhance bone regeneration have a wealth of potential clinical applications from the treatment of nonunion fractures to spinal fusion. The use of porous material scaffolds from bioceramic and polymer components to support bone cell and tissue growth is a longstanding area of interest. Current challenges…
Konzertierte Effekte: Triblockpeptidcopolymere, organische mehrzähnige Liganden und Zn2+-Ionen assoziieren in wässriger Lösung bei mittleren pH-Werten spontan zu Nanobändern. Die Nanostrukturen werden durch eine außergewöhnliche Kombination nichtkovalenter Wechselwirkungen stabilisiert: Metall-Ligand-Komplexierung, Wa…
Goldene Ringe: Eine Selbstorganisation, die bindende AuI-AuI-Wechselwirkungen nutzt, führt zu einem riesigen, kronenförmigen Au36-Ringaggregat, das durch durchgängige Metall-Metall-Kontakte gekennzeichnet ist (siehe Bild).
Local electrochemical probes, the Scanning Vibrating Electrode Technique, the electrochemical capillary cell and a pH sensor have been used to study the corrosion behavior of zinc coated low alloy carbon steel cut-edges immersed in 0.03 M NaCl solution. Experimental results show an inhibition of cathodic reactions on…
The surfactants assisted colloidal processing of 1˙0 wt-% carbon nanotube (CNT)–SiO2 composites using acid treated CNTs and colloidal silica has been investigated. By using different combinations of anionic and cationic surfactants five systems were developed with the aim of coating the CNTs with silica particles and…
The effects of partial or complete replacement of two commercial fillers, carbon black (CB) and silica on cure characteristics, tensile properties, fatigue life, morphological properties, and rubber—filler interaction of paper sludge (PS) filled natural rubber composites were elucidated. Compounding was carried out on…
Surface functionalization and modification scheme of cubic boron nitride (cBN) films deposited by chemical vapor deposition was demonstrated. A homogeneous layer of amino groups was bonded covalently on the B and/or N atoms of cBN surface via a photochemical reaction with allylamine. X-ray photoelectron spectroscopy w…
Abstract The network structure, mechanical properties, and thermal gravimetric of epoxy resin filled with plasticized carbon black (CB) have been studied. The effect of CB concentration on composite morphology as well as cross linking density (n), volume fraction of resin (Vr), degree of crystallinity (Xc), mean gap a…
Here, we demonstrate bulk silicon light emitting diodes operating over the 1.2–1.35μm range. This is achieved by the implantation of the rare earth thulium, incorporated in the trivalent Tm3+ state, into silicon p-n junctions. Light emitting diodes operating under forward bias have been obtained by codoping of boron t…
The dissolution of metal clusters in metal island films by the simultaneous application of electric field and temperature is reported. The consequent fading of surface plasmon resonance greatly modifies the optical properties of the samples. The dissolution process is verified in island films of different metals, obta…
In this paper, a detailed model of a solid oxide fuel cell (SOFC) tube is presented. The SOFC tube is discretized along its longitudinal axis. Detailed models of the kinetics of the shift and reforming reactions are introduced in order to evaluate their rates along the SOFC axis. Energy, moles, and mass balances are p…
Abstract The structure of the PA6/mEPDM/EPDMgMA/organoclay ternary hybrids was characterized and related to its properties. The nanoblends were prepared through four different blending sequences based on one‐ or two‐step processes: (1) The PA6/organoclay nanocomposite was prepared and then mixed with the mEPDM+ EPDMgM…
