The internal Mg diffusion (IMD) process produces a high-density MgB 2 layer with high critical current properties, which makes it an attractive and promising method for fabricating MgB 2 wires. We have obtained high critical current properties in our previous research. However, IMD-processed MgB 2 wires can have unrea…
BACKGROUND: Collagen-rich tendons and ligaments are important for joint stability and force transmission, but the capacity to form new tendon is poorly understood. In the present study, we investigated mechanical strength, fibril size, and structure during development of tendon-like tissue from adult human tenocytes (…
We examine the possibility of using negative refraction stemming from the phonon polariton response in an anisotropic crystal to create a simple slab lens with plane parallel sides, and show that imaging from such a lens should be possible at room temperature despite the effects of absorption that are inevitably prese…
Abstract Supported ionic liquid phase (SILP) catalysts consist of a homogeneous catalyst that is dissolved in an ionic liquid and dispersed on a porous support material. This immobilization technique yields solid catalysts that can be applied in continuous gas phase processes. Recently, several successful applications…
Cationic iridium complexes incorporated 4,5-diaza-9,9'-spirobifluorene as N(∧)N ancillary ligands, in which one (2) or two (3) phenyl groups were introduced onto 4,5-diazafluorene to afford intraligand π-π interactions. The X-ray crystal structures of complexes 2 and 3 show that the pendant phenyl ring forms strong in…
Abstract It is demonstrated that a significant drag reduction for pressure-driven flows can be realized by applying spatially distributed heating. The heating creates separation bubbles that separate the stream from the bounding walls and, at the same time, alter the distribution of the Reynolds stress, thereby provid…
A CdS/TiO2 photocatalyst modified with a Pd co-catalyst was applied to a photocatalytic system for the selective dehydrogenation of benzyl alcohol to benzaldehyde with high selectivity (>99%) accompanied by the formation of H2 in aqueous solution under visible-light irradiation.
A new planar conjugated polymer, poly{benzo(1,2-b:3,4-b′:5,6-d′′)trithiophene-alt-4,4′-dihexyl-2,2′-bithiazole} (BTT-BTz), with a broad band gap and higher Voc based on benzotrithiophene and bithiazole units, was designed and synthesized. This copolymer possesses a deeper HOMO (−5.65 eV), and after 1,8-diiodoctane tre…
By means of nuclear spin-lattice relaxation rate ${T}_{1}^{\ensuremath{-}1}$, we follow the spin dynamics as a function of the applied magnetic field in two gapped quasi-one-dimensional quantum antiferromagnets: the anisotropic spin-chain system ${\mathrm{NiCl}}_{2}\mathrm{\text{\ensuremath{-}}}4\mathrm{SC}({\mathrm{N…
Abstract The fabrication of large area binary magnetic nanostructures made from one or two ferromagnetic materials (Ni and Ni80Fe20) is reported using self‐aligned shadow deposition technique. The static and dynamic properties are characterized using magneto‐optical Kerr effects (MOKE) and broadband ferromagnetic reso…
The synthesis and characterization of a series of chiral zinc complexes ( L 1a – m )ZnN(SiMe 3 ) 2 ( 2a – m ) with C 1 - symmetric amido-oxazolinate ligands ( HL 1a – m = 2-(2′-R 1 NH)phenyl-4-R 2 -oxazoline) have been described. Single-crystal X-ray crystallographic studies confirm that 2a (R 1 = 2,6-dimethylphenyl,…
A novel pathway is presented to transfer and embed functional patterned magnetic nanostructures into flexible and stretchable polymeric membranes. The geometrical and magnetic properties are maintained through the process, realized even directly inside a microfluidic channel. These results pave the way to the realizat…
Abstract Based on an equilibrium fluid model, built from the commercial Fluent software previously validated for thermal plasma characterizations on several geometries, a non-equilibrium two-temperature model was developed. This kind of model needs the use of two energy equations: one for the electrons, and the other…
We propose a model for the intrinsic quantum criticality of $\ensuremath{\beta}\mathrm{\text{\ensuremath{-}}}{\mathrm{YbAlB}}_{4}$, in which a vortex in momentum space gives rise to a new type of Fermi surface singularity. The unquenched angular momentum of the $|J=7/2,{m}_{J}=\ifmmode\pm\else\textpm\fi{}5/2⟩$ Yb $4f$…
Membrane nanotubes can facilitate direct intercellular communication between cells and provide a unique channel for intercellular transfer of cellular contents. However, the transport mechanisms of membrane nanotubes remain poorly understood between cancer cells. Also largely unknown is the transport pattern mediated…
In this study, we present a new route to synthesize an intelligent polymer nanocapsule with an ultrathin membrane based on surface-initiated reversible addition-fragmentation chain-transfer polymerization. The key concept of our report is to use pH-responsive polydiethylaminoethylmethacrylate as a main membrane-genera…
Monocentric lenses have recently changed from primarily a historic curiosity to a potential solution for panoramic high-resolution imagers, where the spherical image surface is directly detected by curved image sensors or optically transferred onto multiple conventional flat focal planes. We compare imaging and wavegu…
Abstract Window‐ or building‐integrated semi‐transparent solar cells are particularly interesting applications for organic photovoltaic devices. In this work, we present an easy‐to‐process inverted device architecture comprising fully solution processable poly(3,4‐ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PS…
Sustainable alternatives for high-performance and functional materials based on renewable resources are intensely needed as future alternatives for present-day, fossil-based materials. Nanochitin represents an emerging class of highly crystalline bionanoparticles with high intrinsic mechanical properties and the abili…
Synthesis of polyesters bearing pendant amine groups with controlled molecular weights and narrow molecular weight distributions was achieved through ring-opening polymerization of 5-(4-(prop-2-yn-1-yloxy)benzyl)-1,3-dioxolane-2,4-dione, an O-carboxyanhydride derived from tyrosine, followed by thiol-yne "click" photoc…
