In this paper, a detached zero index metamaterial lens (ZIML) consisting of metal strips and modified split ring resonators (MSRRs) is proposed for antenna gain enhancement.The effective permittivity and permeability of the detached ZIML are designed to synchronously approach zero, which leads the ZIML to having an ef…
Density functional theory (DFT) calculations have been employed to investigate the interaction between ZnO-(101[combining macron]0) and (12[combining macron]10) surfaces and organic functional groups. We analyze the influence of the surface coverage on the geometries and binding energies under a dry environment. Our c…
Two new coordination polymers have been synthesized with Mn(2+) and Dy(3+) ions using a new bent ether-bridged tricarboxylic acid ligand, o-cpiaH(3) (5-(2-carboxy-phenoxy)-isophthalic acid). The ligand readily reacts with a Mn(2+) salt in presence of pyridine (py) under hydrothermal condition to afford a 3D coordinati…
The present research introduces the concept of developing a novel nanohybrid system based on fluorescent quantum dots coupled to polymer–protein bioconjugates for the detection of potential biological hazards. The organic–inorganic hybrids were constructed by the chemical conjugation of carboxylic functionalized poly(…
Indium tin oxide (ITO) films with high visible transmittance were fabricated on polymethyl methacrylate (PMMA) flexible substrate at room temperature by radio frequency (RF) magnetron sputtering. The deposition rate, microstructure, surface roughness, electrical and optical properties of these films have been investig…
With the decrease in pH value, the 'nano-flower' exhibited a half-open state to expose the target ligands on the surface under tumor acidic conditions and fully bloomed to release Dox under endosomal acidic conditions.
Low temperature solid oxide fuel cells (LT-SOFCs) were operated with a JP5 model reformate. SOFC performance with the reformate showed only a 15% decrease compared to H2 below 600 °C and was stable at 550 °C up to 500 h without observable coking of the anode, indicating feasibility of LT-SOFCs on liquid hydrocarbons f…
Two tetranuclear manganese(II) complexes {K(+)[Mn(4)(ThiaSO(2))(2)(OH)](-)} (1) and {K(+)[Mn(4)(ThiaSO(2))(2)(F)](-)} (2) have been synthesized under solvothermal conditions in methanol with p-tert-butylsulfonylcalix[4]arene (ThiaSO(2)). For both complexes, the structure has been established from single-crystal X-ray…
Well‐aligned and uniform side‐by‐side bicomponent fibers have been produced via dual‐opposite‐spinneret electrospinning. Side‐by‐side TiO 2 /SnO 2 nanofibers were obtained after calcining as‐spun fibers. The thermal degradation of the electrospun fibers was evaluated using combined thermogravimetry and differential th…
Bacterial flagella are naturally-occurring self-assembling protein nanofibers protruding from the bacterial surface to assist the swimming of bacteria. They are rigid and exhibit diverse morphologies depending on the ionic strength, the pH values, temperature, and subunit sequences. Here, the silica nanotubes (SNTs) w…
We present measurements of the polarized extinction of gold nanorod suspensions exposed to an external electric field. By employing an amplitude modulated field in combination with lock-in detection we resolve changes in the optical density as low as 10(-6) in an integration time of 10 s. This sensitivity allows us to…
Hollow Glass Microspheres are high-strength, low-density additives made from water resistant and chemically-stable soda-lime-borosilicate glass. These hollow glass microspheres offer a variety of advantages over conventional irregularly-shaped mineral fillers or glass fiber. Their spherical shape helps reduce resin co…
Based on first principles electronic structure calculations using the Coherent Potential Approximation (CPA) in the Blackman–Esterling–Berk (BEB) multiscattering formalism and the variable range hopping (VRH) model proposed by Mott, we evaluate the low temperature dc conductivity and its temperature dependence for n-d…
Reaction of imidazole aldehydes with dihydrazino derivatives of 2-phenylpyrimidine provides a family of bis(acylhydrazone) ligands which form [2 × 2] metallogrid complexes with transition metal ions including Fe(II), Co(II), Cu(II) and Zn(II). The free ligands show H-bonding interactions, both donor and acceptor, larg…
We synthesized polymethacrylate with a diphenyl-diacetylene moiety in the side chain. It formed a nematic LC, which appears in the wide temperature region and vitrified at room temperature. The polymer exhibited a high-birefringence of ∼0.3 at 550 nm at room temperature.
Modification of bone implant materials with biofunctional surfaces that facilitate osteoblast adhesion and promote matrix mineralization is an attractive strategy to improve osseointegration. This manuscript discusses the preparation and properties of RGD peptide modified poly(2-hydroxyethyl methacrylate-co-2-(methacr…
SERS substrates fabricated from chemically synthesized nanoparticles (NPs) offer a distinct advantage of localizing and enhancing the electromagnetic fields by facile tuning of NP size, shape and interparticle distances. In this report, two-dimensional arrays of micrometre-sized clusters of gold nanoparticles protecte…
This communication describes a one-step strategy for the facile synthesis of polymer-Au patchy particles (PPs) and Au nanocups using the interfacial reactions.
We experimentally demonstrate that gain materials properly encapsulated into the shell surrounding metal nanoparticles (NPs) are responsible for the modification of the overall plasmon response of engineered nanostructures. A comparison between designed systems based on functionalized core–shell NPs having different e…
In this article, a multiple-responsive polymer micelles system was constructed by using an ionic bond as the link to connect the hydrophobic tetraphenylthiophene (TP) fluorophores having aggregation-induced emission enhancement (AIEE), and the hydrophilic poly(N-isopropyl acrylamide) (PNIPAM). The susceptibility of th…
