Electrochemistry-controlled metal ion release is achieved using nanoparticle mixtures embedded into a silicone matrix. Synergistic metal ion release from silicone matrix filled with silver and copper nanoparticles as well as silver and gold nanoparticles embedded into silicone is investigated in terms of qualitative a…
To achieve a targeted drug delivery system for chemotherapy, we synthesized a ligand-mediated nanoparticulate drug carrier composed of folate-conjugated heparin-based copolymers. The use of a heparin-based drug delivery system is of special interest due to the attractive anticancer properties of heparin. Heparin–poly(…
Phase-pure porous nanospheres, both In(OH)3 and InOOH, have been prepared through a facile hydrothermal method using different organic acids as the assistant agents. The organic acids play an important role in the phase change, and the phase composition of the precursors could be deliberately controlled by adjusting t…
We study the formation of topological defects in nematic liquid crystals confined in open bicontinuous networks produced in glass by femtosecond laser micromachining. We obtain a careful classification of the number and localisation of the defects as a function of the topological properties of the network. Our finding…
Preparation of supramolecular polymer gels based on simple molecular design was demonstrated by blending carboxyl-terminated telechelic polymers and poly(ethyleneimine), where balance of an attractive force due to hydrogen bonding and a repulsive force induced by phase separation between polymers has been found as a k…
Superparamagnetic iron oxide nanoparticles (SPIONs) designed to interact with tumor cells have received increasing interest in the past few years, due to their potential for applications such as magnetic resonance imaging (MRI) contrast enhancement, drug delivery, and hyperthermia. However, the stability of these nano…
The assembly of a tetradeca-manganese magnetic cluster [Mn(14)W(48)O(192)H(20)](26-), containing two high spin Mn(7) cores and supported exclusively by isopolytungstate ligands, demonstrates the promising perspective of using "defect" isopolyanions as ligands/synthons to construct large aggregated structures and model…
The existence of Mg(B12H12) as an intermediate compound during the dehydrogenation process of Mg(BH4)2 has been verified. To elucidate the formation process of Mg(B12H12), the dehydrogenation products of Mg(BH4)2 at different temperatures were characterized via X-ray diffraction and 11B magic angle spinning NMR measur…
Single-walled carbon nanotubes (SWCNTs) have attracted great interest in the last two decades because of their unique electrical, optical, thermal, mechanical properties, etc. One major research field of SWCNTs is the controlled growth of them from the patterned catalysts on substrates, since the integration of SWCNTs…
INTRODUCTION: In this work, the use of β-cyclodextrine (β-CD)-modified dendrimers as a nanocapsule with a biocompatible shell have studied. β-CD-modifieddendrimers have designed and synthesized to enhance the loading capacity of the final dendrimers with encapsulation properties. METHODS: To achieve β-CD-modified dend…
This letter presents a compact zeroth-order resonance (ZOR) antenna based on a new type of composite right/left-handed (CRLH) transmission-line unit-cells structure. It has a coplanar waveguide (CPW)-fed input port with modified common ground plane. The unit cell of the proposed antenna consists of a series metal-insu…
We report on a flexible quantum dot-sensitized solar cell (QDSSC) based on ZnO nanorods with a length of 2 μm. Due to the good coverage of CdSe QDs on ZnO by the electrophoretic deposition method, a maximum power conversion efficiency of ∼1% is achieved for the flexible QDSSC.

We present a new strategy to disassemble amyloid fibrils consisting of a supramolecular attachment along the fibrils’ contour length of end-terminated counter charged hydrophilic polymers. We chose as a model system to work with positively charged β-lactoglobulin fibrils (pH 2), to which sulfonic acid terminated poly(…
Rose-like NiO structures were fabricated by calcining the solvothermally formed α-Ni(OH)2 structure with similar morphology. The product was characterized by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, high-resolution transmission electron microscopy, Fourier transform infrared s…
Physical methods of wastewater treatment are useful in water purification and recycling. We have proposed the role of nanoparticle in combination with ultrasound. Ultrasound (US), nanoparticle (NP) or in combination (US + NP) may offer an attractive proposition in the area of water purification. Ultrasound irradiation…
We have been developing host–guest methodology for the separation of single-walled carbon nanotubes (SWNTs) according to handedness and diameter with gable-type chiral diporphyrins. The diporphyrins, designated as porphyrin nanotweezers, consist of two porphyrins and rigid spacer in between. As an extension of our str…
A conventional convex lens is compressed into a flat one based on a so-called discrete coordinate transformation technique. While maintaining a good performance of the original lens, such a transformed flat lens only requires a few blocks of isotropic dielectrics. Physical realization via multiple transmission lines i…
The crystal structures and magnetic properties of two novel polyclusters {[Cu(3)(tci)(2)(H(2)O)(2)]·12H(2)O}(n) (1) and {[Cu(3)(tci)(2)(H(2)O)(2)]·6H(2)O}(n) (2) (tci = tris(2-carboxyethyl) isocyanurate) are investigated. The X-ray crystallographic analysis reveals that they contain interesting infinite alternating ch…
It is very important to know the morphology and chemical properties of subscales of oxide layers on surface for controlling and understanding high temperature oxidation in electrical steel. In present work, the oxide layers were investigated by various methods of transmission electron microscopy (TEM) such as scanning…
