Graphene is a unique 2D system of confined electrons with an unusual electronic structure of two inverted Dirac cones touching at a single point, with high electron mobility and promising microelectronics applications. The clean system has been studied extensively, but metal adsorption studies in controlled experiment…
The authors report the growth of nanowires by heating the GaN/sapphire template. It was found that density, average length, and average diameter of the nanowires all increased as we increased the grown temperature. It was also found that β-Ga2O3nanowires with good crystal quality could be achieved only at high tempera…
Ein aktiver Beitrag: Die spezifische Kapazität kohlenstoffbasierter Superkondensatoren lässt sich durch Zugabe einer elektrochemisch aktiven Verbindung (Hydrochinon) zum Leitsalz deutlich erhöhen (siehe Bild; Molekülstrukturen: grau C, weiß H, rot O). Der starke Beitrag des redoxaktiven Elektrolyten zur Pseudokapazitä…
The heterolytic dissociation of water with the previously unknown four-coordinated syn-linear (μ-oxo)divanadium core to form the five-coordinated bis(μ-hydroxo)divanadium core was confirmed by a crystal-to-crystal transformation.
Polyhedral oligomeric silsesquioxane (POSS)-polyimide (PI) hybrid nanocomposites were prepared from ether linked cyclohexyl diamine (ELCD)-modified polyamic acid with POSS derivative of octaaminophenylsilsesquioxane (OAPS). Polyamic acid (PAA) was prepared by reacting ELCD with pryomelletic dianhydride (PMDA) in 1-met…
This work is devoted to the fundamental understanding of the interaction between acoustic vibrations and surface plasmons in metallic nano-objects. The acoustoplasmonic properties of coupled spherical gold nanoparticles and nanodisk trimers are investigated experimentally by optical transmission measurements and reson…
Conductive diamond whiskers were fabricated by maskless oxygen plasma etching on highly boron-doped diamond substrates. The effects of the etching conditions and the boron concentration in diamond on the whisker morphology and overall substrate coverage were investigated. High boron-doping levels (greater than 8.4 × 1…
The orientation of cylinder-forming poly(styrene-block-methyl methacrylate) [P(S-b-MMA)] was investigated on two sets of polymeric surface treatments: 10 para-substituted polystyrene derivatives with <10 mol % poly(4-vinylbenzyl azide) and a series of poly(styrene-random-4-vinylbenzyl azide) [P(S-r-VBzAz)] copolymers…
The classical pathway of complement is an essential component of the human innate immune system involved in the defense against pathogens as well as in the clearance of altered self-components. Activation of this pathway is triggered by C1, a multimolecular complex comprising a recognition protein C1q associated with…
Electrospinning is a widely established polymer-processing technology that allows generation of fibers (in nanometer to micrometer size) that can be collected to form nonwoven structures. By choosing suitable process parameters and appropriate solvent systems, fiber size can be controlled. Since the technology allows…
Mineralized biological materials such as shells, skeleton, and teeth experience biomineralization. Biomimetic materials exploit the biomineralization process to form functional organic-inorganic hybrid nanostructures. In this work, we mimicked the biomineralization process by the de novo design of an amyloid-like pept…
Intended as a textbook for courses involving preparative solid-state chemistry, this book offers clear and detailed descriptions on how to prepare a selection of inorganic materials that exhibit important optical, magnetic and electrical properties, on a laboratory scale. The text covers a wide range of preparative me…
We present a general theory of phononic heat transfer between two solids (or a solid and a fluid) in contact at a flat interface. We present simple analytical results which can be used to estimate the heat transfer coefficient (the inverse of which is usually called the 'thermal boundary resistance' or 'Kapitza resist…
Abstract Struvite‐K is the natural potassium equivalent to Struvite. Struvite‐K crystals were grown by single diffusion gel growth technique in silica hydro gel medium. Struvite‐K crystals with different morphologies having transparent to translucent diaphaneity were grown with different growth parameters. The phenome…
Traditional single-fiber pull-out type experiments were conducted on individual multiwalled carbon nanotubes (MWNT) embedded in an epoxy matrix using a novel technique. Remarkably, the results are qualitatively consistent with the predictions of continuum fracture mechanics models. Unstable interface crack propagation…
The variation of photon attenuation coefficient on the chemical media has been investigated. For this purposes the linear attenuations of barite concrete have been measured at 662, 1773 and 1332 keV before leaving the chemical media and following a 6 month period. The linear attenuation coefficients have been measured…
Single-needle systems have been used in electrospinning experimental research; however, the low fluid throughput in fiber production has industrial limitations. To meet a high liquid-throughput requirement, several multijet schemes have recently been tested. The main drawback of these schemes is the deterioration of t…
We present an electron-cyclotron-resonance plasma source with a biased sample holder that is well suited for the implantation of deuterium ions into tungsten. Achievable energies range from several electronvolts up to 200 eV per deuteron. The deuterium ion fluxes from this plasma source were thoroughly quantified with…
The layer-by-layer assembly of sequentially adsorbed, alternating polyelectrolytes has become increasingly important over the past two decades. The ease and versatility in assembling polyelectrolyte multilayers (PEMs) has resulted in numerous wide ranging applications of these materials. More recently, PEMs are being…
