This paper described the synthesis of copolymer emulsions of fluorine and siloxane‐containing acrylates for water‐repellent cotton fabrics coatings. Chemical composition, morphology structure, and properties of the latex copolymers were investigated by Fourier transform infrared (FTIR), dynamic light scattering (DLS),…
Graphene can be synthesized from polyacrylonitrile (PAN) polymer through pyrolysis. A metal catalyst such as nickel (Ni) is required for the conversion of the polymer to graphene. The metal catalysts can be placed either atop or underneath the polymer precursor. We observed that spatially non-uniform and disconnected…
Highly ordered and vertically aligned ZnO nanorods using an inverted self-assembled monolayer (SAM) template was fabricated via the hydrothermal process, and few-layer graphene was transferred on the surface of the ZnO nanorod arrays with 20 nm Au nanospheres coverage on the graphene surface. The band edge emission of…
Point-contact Andreev-reflection spectroscopy in Fe(Te,Se) films: multiband superconductivity and electron-boson coupling, Daghero, D, Pecchio, P, Ummarino, G A, Nabeshima, F, Imai, Y, Maeda, A, Tsukada, I, Komiya, S, Gonnelli, R S
Here in this work, we report the fabrication of a (metal) ion selective surface enhanced Raman scattering (SERS) optrode, the counterpart of an ion selective electrode, for the detection of metal ions in solution. Following our previous work, a layer-by-layer self-assembly strategy was used to fabricate the SERS optro…
The antioxidant quercetin was incorporated into high density polyethylene (HDPE) and ethylene-vinyl acetate copolymer (EVA) films by flat compression. The mass ratio of HDPE : EVA was 65 : 35, and the amount of quercetin in the films was 0.74% (wt%) and 1.23%, respectively. The method of manufacturing the films achiev…
The production of titanium dioxide nanoparticles (TiO(2) NPs) for commercial applications has greatly increased over the last years and consequently the potential risk for human health. There is a growing awareness of the need to understand the behavior and influence these nanoparticles exert on the environment. Bioac…
Electrospun scaffolds mimic the microstructure of structural collagenous tissues and have been widely used in tissue engineering applications. Both brittle cracking and ductile failure have been observed in scaffolds with similarly random fibrous morphology. Finite element analysis can be used to qualitatively examine…
We describe the use of cadmium telluride quantum dots (CdTe QDs) as antennas for the photosensitization of nitric oxide release from a ruthenium nitrosyl complex with visible light excitation. The CdTe QDs were capped with mercaptopropionic acid to make them water-soluble, and the ruthenium nitrosyl complex was cis-[R…
We present a new, simple, quick and ecologically friendly method of exfoliating graphite to produce graphene. The method is based on the intercalation of a permanganate M2MnO4 (M=K, Na, Li), which is formed by the reaction of a manganate MMnO4 with an alkali metal hydroxide MOH. The quality of exfoliation and the morp…
The coordination of cyclic β-D-glucose (CDG) to both [Al(OH)(aq)](2+) and [Al(OH)2(aq)](1+) ions has been theoretically investigated, using quantum chemical calculations at the PBE0/6-311++G(d,p), aug-cc-pvtz level under polarizable continuum model IEF-PCM, and molecular dynamics simulations. [Al(OH)(aq)](2+) ion pref…
Recent work [Mahynski et al., Nat. Commun., 2014, 5, 4472] has demonstrated that the addition of long linear homopolymers thermodynamically biases crystallizing hard-sphere colloids to produce the hexagonal close-packed (HCP) polymorph over the closely related face-centered cubic (FCC) structure when the polymers and…
ABSTRACT A three‐phase water‐soluble nanocomposite of single wall carbon nanotube/silver nanoparticle hybrid fibers embedded in sulfonated polyaniline has been synthesized by a simple chemical solution mixing process. The nanocomposite has been characterized by high resolution electron microscopy, X‐ray diffractometry…
ABSTRACT A series of poly(propylene carbonate) (PPC)/aluminum flake (ALF) composite films with different ALF contents were prepared via a melt‐blending method. Their cross‐section morphologies, thermal properties, tensile strength (TS), and gas barrier properties were investigated as a function of ALF contents. SEM im…
Aluminium (Al) nanoparticles (NPs) over a 1.2‐cm 2 ‐size area are fabricated using nanoporous anodic aluminium oxide as shadow masks. With this technique, plasmon response of Al NP arrays with different out‐of‐plane height is investigated. The dipolar‐localized surface plasmon resonances (LSPRs) peak of Al NP arrays i…
In order to accurately assess the potential environmental risk posed by silver nanoparticles (Ag-NPs), their transformation and fate must be investigated in natural systems. This has proven to be very challenging due to the difficulties encountered in retrieving/analyzing NPs dispersed in complex and heterogeneous env…
In this study, the ability of methotrexate (MTX)-loaded stimuli-responsive novel silica nanocomposites (MSNs) (with mean diameter of ± 60 nm) in the induction of apoptosis, and change in the Bax/Bcl-2 mRNA levels, were investigated. MTT assay and RT -PCR analysis were performed on MDA-MB-231 breast cancer cells, to ev…
Using the experimentally measured temperature- and doping-dependent structural parameters on Ru-doped BaFe 2 As 2 , orbital-dependent reconstruction of the electronic structure across the magnetostructural transition is found, through first principles simulations. Below structural transition there exist two distinct F…
Poly(carbonate‐urethane‐urea)s (PCUU) based on oligocarbonate diols (M n ≈ 2000) with different length of the hydrocarbon chain as soft segments were synthesized and investigated. Carbonate oligomerols were obtained in a two‐step method from dimethyl carbonate (DMC) and linear α,ω‐diols (1,4‐butanediol, 1,5‐pentanedio…
The effect of the surface topography on the protein adsorption process is of great significance for designing biomaterial surfaces and the biocompatibility for specific biomedical applications. In this work, we have systematically investigated the mono‐protein adsorption kinetics of bovine serum albumin (BSA) and fibr…
