Integration of graphene with other materials by direct growth, i.e., not using mechanical transfer procedures, is investigated on the example of metal/graphene/dielectric heterostructures. Such structures may become useful in spintronics applications using graphene as a spin-filter. Here, we systematically discuss the…
LyP-1 (CGNKRTRGC) is a nine amino acid peptide that shows high specificity for tumor lymphatics. The aim of this study was to develop lipid-based formulations containing the linear form of LyP-1 for lymphatic targeting. Self-microemulsifying drug delivery systems (SMEDDS) were designed for the delivery of linear LyP-1…
A facile approach was developed to prepare multi-walled carbon nanotubes/graphene nanoplatelets hybrid materials through covalent bond formation. First, poly(acryloyl chloride) was grafted onto oxidized multi-walled carbon nanotubes through the reaction between the acyl chloride groups of poly and the hydroxyl groups…
Nanotechnology is currently employed as a tool to fight more efficiently against human pathogens. Nanoparticles can be prepared from a variety of materials such as protein, biodegradable polymers and synthetic polymers. Tamarindus indica Linn. or tamarind is one of the most important biodegradable polymer. In the pres…
In this study, the Raman spectral characteristics of 1,4-phenylenediisocyanide (1,4-PDI) and 4-aminobenzenethiol (4-ABT) positioned at the nanogap formed by Au/Ag alloy nanoparticles and a flat Au substrate were examined, and three-dimensional finite-difference time-domain (3-D FDTD) calculations were carried out. A m…
Acid-responsive electrospun fibers are fabricated by introducing sodium bicarbonate into PLLA fibers using an emulsion method. This novel electrospun fibrous scaffold exhibits a rapid acid-responsive controlled drug release (early stage) and stable three-dimensional (3D) structure as a tissue engineering scaffold (lat…
NiO(8 %)/Ni,H-ZSM-5 + Al2O3 (1:1) catalysts differing in metal-support interactions, which influenced the metal-to-acid ratios, were examined. The interactions were changed by modifying the method of zeolite and aluminium hydroxide combining and the method of Ni incorporation. The catalysts were characterised by ICP,…
ABSTRACT The influence of injection molding parameters on electrical properties and morphology of PC/ABS‐MWCNT nanocomposites is presented in this article. Investigation is based on the masterbatch of 5.0 wt % carbon nanotubes obtained by melt‐mixing. Further processing includes dilution of this nanocomposite to desir…
Hybrid materials based on combination of polymers and inorganic nanoparticles (NP) attracted considerable attention in the last decade due to their advantageous electrical, optical, or mechanical properties. Recently, we reported a significant improvement of the photoresponse by doping azopolymers with ZnO NP. To stud…
A low cost, large scale fabrication method of easily achieving superhydrophobic surfaces with very low contact angle hysteresis was reported in this paper. Microstructures were fabricated by the aggregation of the copolymer of styrene and methyl methacrylate using the phase separation method. Nanostructures were also…
The weak ferromagnetic moment in Ni-doped CuB${}_{2}$O${}_{4}$ can be rotated by applying an electric field. While this implies spin-driven ferroelectricity, no direct evidence of electric polarization has been reported to date. Here we report the induction and control of polarization in the borate in the presence of…
Copolyesters based on poly(butylene terephthalate) (PBT) and a bio-based fatty acid dimer diol (FADD) were prepared by solid-state modification (SSM). The chemical incorporation of the FADD into the backbone of the PBT was proven using various techniques. It was clear that the incorporation rate was diffusion-limited…
A detailed microscopic structural study on two single crystalline dilute magnetic oxides, BaTi0.95Fe0.05O(3-δ) with and without perceptible δ, has been carried out. Although it has been reported earlier that varying δ significantly affects high temperature ferromagnetism, the real distribution/redistribution of vacanc…
Thermophysical properties of CO 2 –CH 4 mixtures at high temperatures are very attractive for materials processing. In comparison with argon, at the same temperature, such a mixture possesses much higher enthalpy and higher thermal conductivity. At high temperatures, CO 2 –CH 4 mixture has a complex composition with s…
Ultrathin Ag2Mo3O10·2H2O nanowires (NWs) were synthesized by soft chemistry under atmospheric pressure from a hybrid organic-inorganic polyoxometalate (CH3NH3)2[Mo7O22] and characterized by powder X-ray diffraction, DSC/TGA analyses, FT-IR and FT-Raman spectroscopies, scanning electron microscopy (SEM), and transmissi…
Synthetic biodegradable elastomers are a class of polymers that have demonstrated far-reaching utility as biomaterials for use in many medical applications. Biodegradable elastomers can be broadly classified into networks prepared by either step-growth or chain-growth polymerization. Each processing strategy affords d…
A series of cross-linked chitosan (XCs)-filled chitosan (Cs) matrix, with filler contents of 0 to 12 wt/v% were fabricated using a casting method. Thermal properties of the composites were examined using thermogravimetry (TG), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). Addition of X…
A strategy to replicate fingerprint patterns formed by the self-assembly of lamella-forming block copolymer (BCP) was investigated. To accomplish this, liquid conformal layers were placed between the surfaces of a “master” BCP film and a transparent “replica” substrate that solidified and covalently bonded to the BCP…
A set of parameters for the modified embedded atom method (MEAM) potential was developed to describe the perovskite silver tantalate (AgTaO 3 ). First, MEAM parameters for AgO and TaO were determined based on the structural and elastic properties of the materials in a B1 reference structure predicted by density-functi…
Open-chain pentapyrroles were isolated as side-products from the synthesis of triaryl-corroles and then converted to the corresponding sapphyrins by catalytic oxidation in acidic media. The investigated compounds were characterized by UV-vis and (1)H NMR spectroscopy, mass spectrometry, electrochemistry, and spectroel…
