Abstract This paper reports on a web of superamphiphobic fluoro‐compound fibers that forms as a result of a typical electrospinning method without any additional treatment. An electrospun web of poly(2,2,2‐trifluoroethyl methacrylate) fibers exhibits superamphiphobicity when the water and hexadecane contact angles bot…
The adsorption of HSA onto CHI/ALG multilayer assemblies was assessed in situ using QCM-D. It was found that the behavior of HSA on biomaterials surface can be tuned by adjusting parameters of the polyelectrolyte system such as pH, layer number, crosslinker and polymer terminal layer. Our results confirmed the key rol…
New-phased metastable V(2) O(3) porous urchinlike micronanostructures were first fabricated on a large scale by a simple top-down strategy of pyrolyzing a vanadyl ethylene glycolated precursor in the absence of any templates or matrices. The pyrolysis mechanism was clearly revealed by synchrotron vacuum ultraviolet (V…
The giant electrocaloric (EC) effect is of great importance for application in cooling or heating devices of new generation, which would be friendlier for environment. Recent predictions of the existence of the giant EC effect in polymeric and inorganic ferroelectric relaxors are based solely on the indirect measureme…
Miscibility and crystallization behaviors of poly(ethylene succinate)/poly(p-dioxanone) (PES/PPDO) blends were investigated by differential scanning calorimetry (DSC), polarized optical microscopy (POM), and wide-angle X-ray diffraction (WAXD). PES/PPDO blends are completely miscible as proved by the single grass tran…
It is well known that ${\text{PbO-SiO}}_{2}$ exhibits a wide glass formation composition range, up to $90\text{ }\text{mol}\text{ }\mathrm{%}$ PbO. Earlier studies suggest that the existence of ${\text{PbO}}_{3}$ or ${\text{PbO}}_{4}$ structural units, which act like network formers, may be the reason for the wide gla…
The protein common interface database (ProtCID) is a database that contains clusters of similar homodimeric and heterodimeric interfaces observed in multiple crystal forms (CFs). Such interfaces, especially of homologous but non-identical proteins, have been associated with biologically relevant interactions. In ProtC…
During photoelectron spectroscopy experiments, the spectra of B(11)O(-) and B(10)Au(-) clusters are found to exhibit similar patterns except for a systematic spectral shift of ∼0.5 eV, hinting that they possess similar geometric structures. The electron affinities are measured to be 4.02 ± 0.04 eV for B(11)O and 3.55…
Spider silks exhibit remarkable properties, surpassing most natural and synthetic materials in both strength and toughness. Orb-web spider dragline silk is the focus of intense research by material scientists attempting to mimic these naturally produced fibres. However, biomechanical research on spider silks is often…
The synthesis and radical polymerization of an 18-e cobaltocenium vinyl monomer, 2-acryloyloxyethyl cobaltoceniumcarboxylate hexafluorophosphate (AECoPF 6 ), are reported. The side-chain cobaltocenium-containing polymer, poly(acryloyloxyethyl cobaltoceniumcarboxylate hexafluorophosphate) (PAECoPF 6 ), is a water-solub…
The first hyperpolarizability (β) dispersion curve is measured for the first time for an octupolar nonlinear optical (NLO) molecule (crystal violet, CV) and modeled theoretically, yielding an in-depth understanding of the electronic structure and vibronic and solvation effects on such octupolar conjugated systems. Tun…
A voltage-controlled resistive switching is predicted for ferromagnetic multilayers and spin valves mechanically coupled to a ferroelectric substrate. The switching between low- and high-resistance states results from the strain-driven magnetization reorientations by about 90°, which are shown to occur in ferromagneti…
Nanotechnology is currently undergoing an impressive expansion in material science research and development of systems that have novel properties due to their small size. Most of the research efforts have been focused on applications, while the implications efforts (i.e., environmental health and safety) have lagged b…
We have synthesized two different fullerene-subphthalocyanine-ferrocene conjugates. The molecules were designed so that the ferrocene unit is linked at the subphthalocyanine axial position through a phenoxy spacer while the C(60) is rigidly held close to the concave face of the macrocycle via a 3-fold C(3)-symmetrical…
Inorganic nanoparticles offer great opportunities in biomedicine, for example, serving as contrast agents for imaging, hyperthermia agents and drug delivery vehicles. A critical factor limiting the applications of nanoparticles for therapeutic and diagnostic purposes is their short circulation time in vivo due to clea…
Diffusion of a graphene flake on a graphene layer is analyzed and a diffusion mechanism is proposed for the system under consideration. According to this mechanism, rotational transition of the flake from commensurate to incommensurate states takes place with subsequent simultaneous rotation and translational motion u…
In this paper we highlight the accurate spectral detection of bovine serum albumin and ribonuclease-A using a surface-enhanced Raman scattering (SERS) substrate based on gold nanocylinders obtained by electron-beam lithography (EBL). The nanocylinders have diameters from 100 to 180 nm with a gap of 200 nm. We demonstr…
The functional properties of many technological surfaces in biotechnology, electronics, and mechanical engineering depend to a large degree on the individual features of their nanoscale surface texture, which in turn are a function of the surface manufacturing process. Among these features, the surface irregularities…
The dynamic structures of the cubic and tetragonal phase in BaTiO3 and its dielectric response above the cubic-to-tetragonal phase transition temperature (Tp) are studied by first-principles molecular dynamics (MD) simulation. It's shown that the phase transition is due to the condensation of one of the transverse cor…
We consider ferroelastic first-order phase transitions with $N_{OP}$ order-parameter strains entering Landau free energies as invariant polynomials, that have $N_V$ structural-variant Landau minima. The total free energy includes (seemingly innocuous) harmonic terms, in the $n = 6 -N_{OP}$ {\it non}-order-parameter st…
