The thermal boundary resistance between an individual carbon nanotube and a Au surface was measured using a microfabricated hot-film sensor. We used both closed and open-ended multi-walled carbon nanotubes and obtained thermal boundary resistance values of 0.947-1.22 × 10(7) K W(-1) and 1.43-1.76 × 10(7) K W(-1), resp…
Poly(1,4-naphthalenevinylene), prepared from a water-soluble precursor, was used to fabricate hybrid solar cells by blending with water-soluble CdTe nanocrystals (NCs) to act as the photoactive layer. In composites with CdTe NCs as the electron acceptors in a bulk heterojunction configuration, the devices exhibited a…
Electrospinning using synthetic and natural polymers is a promising technique for the fabrication of scaffolds for tissue engineering. Numerous synthetic polymers are available to maximize durability and mechanical properties (polyurethane) versus degradability and cell adhesion (polycaprolactone). In this study, we e…
N,N-bis(2-hydroxybenzyl)alkylamines, benzoxazine dimers, are the major product produced from benzoxazine monomers on mono-functional phenol by the one step ring opening reaction. Due to the metal responsive property of benzoxazine dimers, in this present work, N,N-bis(5-methyl-2-hydroxybenzyl)methylamine (MMD), N,N-bi…
The Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) allows the efficient and complete functionalization of dendrimers with preformed Gd chelates (prelabeling) to give monodisperse macromolecular contrast agents (CAs) for magnetic resonance imaging (MRI). This monodispersity contrasts with the typical distribution o…
A series of aromatic polyester polyols (APP) were synthesized by transesterification of industrial poly(ethylene terephthalate) (PET) waste using di(ethylene glycol) in the presence or absence of glycerol, adipic acid, poly(propylene glycol), or hexanediol as functional additives. PET-waste-derived modified APP was us…
We demonstrate electrical control of the single-photon emission spectrum from chromium-based colour centres implanted in monolithic diamond. Under an external electric field, the tunability range is typically three orders of magnitude larger than the radiative linewidth and at least one order of magnitude larger than…
Various chemicals are being explored for catalyzing efficient lignocellulose deconstruction. In particular, when liquid ammonia is used to convert the naturally occurring cellulose crystalline phase I(β), to cellulose III(I), the rearrangement of the hydrogen bond network in cellulose III(I) results in enhanced hydrol…
Three-dimensional (3D) assemblies of metal nanoparticles are promising materials for plasmonic materials. Metal nanoparticles have unique surface plasmon resonances, ranging from ultraviolet to visible light wavelengths, depending on their metal species, size, and shape. The arrangements and spacing of the nanoparticl…
pH-sensitive photoluminescence (PL) is an important property of aqueous nanocrystals (NCs) towards NCs-based intelligent applications. Previous works mainly focused on the effect of pH during NC growth process on PL of the aqueous NCs. The effect of pH during application process on PL of as-prepared NCs is still not f…
Abstract The film growth and the properties of plasma polymers are determined by gas phase and surface reactions. In order to gain more insights and to optimize plasma polymerization processes, some assumptions can be made that allow a macroscopic approach. Therefore, a concept was developed based on the energy input…
We study the single file diffusion of a cyclic chain of particles that cannot cross each other, in a thermal bath, with long-ranged interactions and arbitrary damping. We present simulations that exhibit new behaviors specifically associated with systems of small numbers of particles and with small damping. In order t…
Planar anisotropy Y 2 Fe 17 powders were fabricated by rapid quenching and ball-milling techniques. The frequency dependence of complex permeability and permittivity of paraffin composites with 35 vol% Y 2 Fe 17 powders have been investigated in the frequency range 0.1–10 GHz. The oriented composite shows a dramatic i…
To obtain depth profiles of surface-enhanced Raman scattering (SERS) information in living systems, a SERS-active needle was structured by acupuncture needles, gold nanoshells (GNSs), and polystyrene, which were used as carriers, SERS-active elements to be absorbed on the carriers, and coatings to protect the absorbed…
Abstract The effect of CO 2 ‐induced crystallization on the mechanical properties, in particular the yield and the ultimate stresses, of polyolefins is studied. PP and SEBS copolymer blends are used as examples and foamed after sorption of CO 2 at temperatures below T m . CO 2 sorption thickens the crystalline lamella…
Veredelte Nanoröhren: Das erste nanoröhrenbasierte katalytische System für die Silan-Oxidation wird beschrieben (siehe Schema). Das wiederverwendbare Gold-Nanoröhren-Hybrid oxidiert unter milden Bedingungen sowohl Alkyl- als auch Arylsilane in hohen Ausbeuten und ist hinsichtlich Gesamteffizienz und Umsatzgrad anderen…
This work describes the synthesis of novel functional silica materials with difunctional thiol-amide substructures and featuring regular architectures on a mesoscopic level. The functional materials were synthesised by both one-pot co-condensation and post-grafting approaches. The thiol groups confined in the matrix w…
In order to enhance the radiation energy of reversed Cherenkov radiation (RCR), on the basis of the single charged particle model, we developed a theoretical method using a charged particle beam bunch to enhance RCR in a circular waveguide partially filled with anisotropic double-negative metamaterials (DNMs). In this…
The coupled dynamics of electrons and optical phonons in graphene is investigated. For this purpose, a kinetic model based on space-dependent Boltzmann transport equations for electrons and optical phonons is established. This system is solved by deterministic methods that provide efficiently accurate results by dynam…
Continuum solvation methods are frequently used to increase the efficiency of computational methods to estimate free energies. In this paper, we have evaluated how well such methods estimate the nonpolar solvation free-energy change when a ligand binds to a protein. Three different continuum methods at various levels…
