We study the effects of bifunctional linker on the photovoltaic properties of P3HT/CdSe quantum dot-linker-ZnO nanocolumn heterostructure. The CdSe quantum dots are bound on the surface of ZnO nanocolumns through either aliphatic linker of 3-aminopropyl trimethoxysilane(APS) or aromatic linker of p-aminophenyl trimeth…
We show that the angular dependence of x-ray magnetic circular dichroism (XMCD) is strongly sensitive to strain-induced electronic structure changes in magnetic transition metal oxides. We observe a pronounced dependence of the XMCD spectral shape on the experimental geometry as well as nonvanishing XMCD with distinct…
OBJECTIVES: The development of nephrogenic systemic fibrosis (NSF) following MRI contrast examination has been associated with gadolinium (Gd) toxicity. Animal models should show the key features of NSF in man where, the only immutable epidemiological feature is renal impairment. A rat model of chronic renal insuffici…
This work brings together dynamical and structural information at a molecular level for cellulose acetate being an original contribution to the general description of polysaccharide properties. In particular, it allowed reinterpreting the secondary relaxation mechanisms that are still controversial in the literature;…
Rare nanostructures having shapes of animals are discussed in detail. Nanoforms, such as nanolarvae, nanoworms, nanosquamae, and nanourchins, of mainly inorganic compounds are examined. These nanostructures possess numerous useful properties (such as magnetic, semiconducting, and field-emitting properties) and applica…
The photoluminescence (PL) quantum yield (QY) is a significant parameter for evaluating the optical properties of fluorescent nanocrystals (NCs). Over the past two decades, different experimental conditions were used for the QY measurement of fluorescent NCs. It makes the reported QY value incomparable in different re…
Abstract In this paper, the effect of organo‐modified montmorillonite (OMMT) on a novel intumescent flame retardant (IFR) system was studied in poly(1,4‐butylene terephthalate) (PBT) composites containing microencapsulated ammonium polyphosphate (MAPP) and melamine cyanurate (MC). Nanocomposite morphology was characte…
Recently, a series of chiral mesoporous silicas with various pore sizes and nanostructures (including chiral MCM-41, chiral SBA-15, and chiral SBA-16) have been successfully synthesized in our group by using achiral templates and a chiral cobalt complex as cotemplate. Enantioselective discrimination ability of these c…
The formation of well-ordered monolayers of hexagonal boron nitride on the surface of a Rh/YSZ/Si(111) multilayer substrate via a three-step boration-oxidation-nitration process was investigated by x-ray photoelectron spectroscopy (XPS), x-ray photoelectron diffraction (XPD) and low-energy electron diffraction (LEED).…
Nanocomposite films of Poly(3,4-ethylenedioxythiophene)-Au−CdSe have been fabricated for the first time by first growing a porous PEDOT layer in the ionic liquid 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide and then introducing the film to a mixed colloid of Au nanoparticles (NPs) and CdSe quantum d…
In this study, a patterned ZnO nanorod array was formed on the ITO layer of GaN-based light-emitting diodes (LEDs), to increase the light extraction efficiency of the LED. The bi-layer imprinted resin pattern was used for selective growth of the ZnO nanorod array on the ITO layer. Compared to conventional LEDs grown o…
Shaping up selectivity: Developments in the synthesis of catalytic particles of targeted size and shape might create opportunities for the design of catalysts for the selective heterogeneous production of low-volume, high-value commodity chemicals. Although these advances are encouraging, scale-up issues in the synthe…
Titanium that is covered with a native oxide layer is widely used as an implant material; however, it is only passively incorporated in the human bone. To increase the implant-bone interaction, one can graft multifunctional phosphonic compounds onto the implant material. Phosphonate groups show excellent adhesion prop…
The unique properties of silk fibroin were combined with keratin to develop new wound-dressing materials. Silk fibroin/keratin (SF/K) films were prepared to reduce high levels of elastase found on chronic wounds. This improved biological function was achieved by the incorporation of a small peptide synthesized based o…
We introduce ultra-fast tunable nanoswitches based on the transition between states of nanoparticle meta-molecules. These molecules are formed (activated) when hybrid systems consisting of metallic nanoparticles and semiconductor quantum dots interact with coherent light sources (laser fields). The switching process o…
The performance of discrete multilayer and continuously graded antireflection coatings for omnidirectional broadband applications are compared. It is shown that in practical cases where refractive index choices are constrained, discrete antireflection coatings can surpass the performance of continuously graded coating…
This review describes the use of polymer micelle nanotechnology based chemotherapies for ovarian cancer. While various chemotherapeutic agents can be utilized to improve the survival rate of patients with ovarian cancer, their distribution throughout the entire body results in high normal organ toxicity. Polymer micel…
Polimide-block-polydimethylsiloxane (PI-b-PDMS) block copolymers have been synthesized from commercially available amino-terminated polysiloxanes with different molecular weights, for use as polymeric materials resistant to the low earth orbit (LEO) space environment. A structural optimization with respect to maximum…
The electronic structure of complex oxides is important for the understanding of their functional properties. In this paper, the electronic structures of the multiferroic perovskite bismuth ferrite $({\text{BiFeO}}_{3})$ and the related isostructural compounds ${\text{Bi}}_{0.9}{\text{La}}_{0.1}{\text{FeO}}_{3}$ and $…
In this study, drug carrier properties through skin and penetration enhancement effects of carbon nanotubes (CNTs) are presented. Multi-walled and double-walled carbon nanotubes were used. Penetration enhancement into the skin following passive diffusion and iontophoresis were determined. Possible solubility enhanceme…
