Blood clotting is a precise cascade engineered to form a clot with temporal and spatial control. Current control of blood clotting is achieved predominantly by anticoagulants and thus inherently one-sided. Here we use a pair of nanorods (NRs) to provide a two-way switch for the blood clotting cascade by utilizing thei…
This work shows a method to synthesize and encapsulate magnetic nickel nanocrystals into polymeric colloidal particles through miniemulsion polymerization. The nickel nanoparticles are produced by a thermal decomposition method in the presence of oleylamine and triphenylphosphine, which results in a hydrophobic surfac…
Aqueous dispersions of lanthanum strontium manganite ( LSM ) and yttria‐stabilized zirconia ( YSZ ) particles were controllably freeze‐cast and then partially sintered resulting in anisotropic, hierarchically porous ceramics for Solid Oxide Fuel Cell ( SOFC ) cathodes. The resulting microstructures have aligned pores…
Transmission lines located in the desert are subjected to desert climate, one of whose features is sandstorms. With long accumulation of sand and with the advent of moisture from rain, ambient humidity and dew, a conductive layer forms and the subsequent leakage current may lead to surface discharge, which may shorten…
The ability to use chalcogenide glass thin films as photoresists for one-step maskless grayscale lithographic patterning is demonstrated. It is shown that the chalcogenide photoresists can be used to fabricate grayscale patterns with smooth and continuous profiles such as arrays of cylindrical and spherical microlense…
Abstract Background Archaeological metallic artefacts buried in soils deteriorate by means of various environmental as well as internal factors and mechanisms over time such as change in composition and microstructure of metal and corrosive factors due to long-term burial environment. Corrosion in metals occurs in dif…
An evolution is currently underway in the textile industry and Textile for Industrial Applications is the guidebook for its growth. This industry can be classified into three categories-clothing, home textile, and industrial textile. Industrial textiles, also known as technical textiles, are a part of the industry tha…
A versatile one-pot strategy for the preparation of reversibly cross-linked polymer-coated mesoporous silica nanoparticles (MSNs) via surface reversible addition-fragmentation chain transfer (RAFT) polymerization is presented for the first time in this paper. The less reactive monomer oligo(ethylene glycol) acrylate (…
High Resolution Image Download MS PowerPoint Slide The anhydrate and the stoichiometric tetarto-hydrate of pyrogallol (0.25 mol water per mol pyrogallol) are both storage stable at ambient conditions, provided that they are phase pure, with the system being at equilibrium at a w (water activity) = 0.15 at 25 °C. Struc…
ABSTRACT The drawbacks of peroxide vulcanization can largely be overcome by introducing suitable co-curing agents (coagents) in the formulation. The role of various coagents, such as zinc diacrylate (ZDA), trimethylolpropane trimethacrylate (TMPTMA), and triallyl cyanurate (TAC) in the peroxide vulcanization of natura…
Abstract Polyurethane sind die einzige Polymerklasse, die abhängig von chemischem und morphologischem Aufbau thermoplastisches, elastomeres oder duromeres Materialverhalten zeigt. Außer den kompakten sind speziell auch die geschäumten Polyurethane weit verbreitet und erzielen die gewünschten Eigenschaften bei niedrigs…
Divalent europium doped barium orthosilicate is a very important phosphor for the production of light emitting diodes (LEDs), generally associated to the green emission color of micron-sized crystals synthesized by means of solid-state reactions. This work presents the combustion synthesis as an energy and time-saving…
An unusual and unique conformation of a paddle wheel type binuclear copper(II) complex containing acetate and acetamido ligands, {Cu2(μ2-O2CCH3)4}(OCNH2CH3) (1), was obtained by solvothermal synthesis. The structural characterization of this compound shows that the apical (acetamido) ligands are disposed at a 62° dihe…
Spiky nanoparticles exhibit higher overall plasmonic excitation cross sections than their nonspiky peers. In this work, we demonstrate a two-step seed-mediated growth method to synthesize a new class of spiky Ag–Au octahedral nanoparticles with the aid of a high molecular weight poly(vinylpyrrolidone) polymer. The len…
Recent advances in both nano-fabrication and nano- materials open up rich new avenues in the optical sensing area. Using nano-grid electrodes, nanometer-scale photo-alignment layers and deformed helix ferro-electric liquid crystals with a sub-wavelength helix pitch of 150 nm, we have realised a fully integrated polari…
Many studies have sought to rationalize property/structure relationships in rare-earth (RE) bearing aluminosilicate oxide or oxynitride glasses. In a set of 48 RE2O3–Al2O3–SiO2 (RE = La, Y, Lu, Sc) glasses of widely spanning compositions and RE3 + cation field-strengths (CFS), we observe strong correlations between th…
An electrical biosensor exploiting a nanostructured semiconductor is a promising technology for the highly sensitive, label-free detection of biomolecules via a straightforward electronic signal. The facile and scalable production of a nanopatterned electrical silicon biosensor by block copolymer (BCP) nano-lithograph…
The surface plasmon resonance has been theoretically investigated in gold nanowires by means of time-dependent density functional theory. Linear chains of Au atoms and nanowires with the structure of the fcc bulk gold grown along the ⟨110⟩ and ⟨111⟩ directions have been considered. The effects of changing the length a…
The objective of this study is to investigate the performance of bamboo fabric–poly(lactic acid) composites manufactured by compression moulding. The effects of compression moulding parameters on the mechanical properties of the bamboo fabric–poly(lactic acid) composite sheets were evaluated. Optimum compression mould…
In this study, ferrimagnetic (SrFe12O19, SrFe12O19/NiFe2O4, and NiFe2O4) nanostructure particles were synthesized by the co-precipitation of chloride salts using the sodium hydroxide solution. The resulting precursors were heat-treated at 1100 °C for 4 h. After cooling in the furnace, the ferrite powders were pressed…
