Cytotoxicity of cadmium-containing silica nanoparticles Cd-SiO2NPs (0.05-100 µg/mL) versus SiO2NPs and CdCl2 was evaluated by an in vitro test battery in A549 by assessing (i) mitochondrial function, (ii) membrane integrity/cell morphology, (iii) cell growth/proliferation, (iv) apoptotic pathway, (v) oxidative stress,…
This paper demonstrated fluorescence behaviour of two novel coumarin-containing dendrigraft polybutadienes (PB-Cou) with linear-comb (LC-PB-Cou) and star-comb (SC-PB-Cou) architectures. LC-PB-Cou and SC-PB-Cou with 12–13 mol% coumarin content were synthesized via the combination of anionic polymerization and “click” c…
Bis-functionalized ferrocenyl units have been attached to organo-functionalized [(R(F)Sn)4S6] double-decker clusters as criss-cross-type intramolecular straps. Two different ways of linking result in different crystal structures and different electrochemical stabilities of the resulting compounds.
In this paper we apply topology optimization to micro-structured superhydrophobic surfaces for the first time. It has been experimentally observed that a droplet suspended on a brush of micrometric posts shows a high static contact angle and low roll-off angle. To keep the fluid from penetrating the space between the…
The composites based on carbon nanotubes (CNTs) and conducting polymers (CPs) are promising materials for supercapacitor devices due to their unique nanostructure that combines the large pseudocapacitance of the CPs with the fast charging/discharging double‐layer capacitance and excellent mechanical properties of the…
We demonstrate a simple and effective approach to control the diameter of ultrathin ZnO nanowires with high aspect ratios and high densities over large areas. Diblock copolymer-based nanoparticle arrays exhibiting a high degree of hexagonal order and offering easy control of particle size (typically 1-10 nm) and inter…
In this work, we demonstrated the purification of amoxicillin trihydrate (AMCT) by the formation of 4-hydroxyphenylglycine (4HPG)-coformer complex in solution. Without advanced knowledge of cocrystal formation of 4HPG, a workflow was established to choose the optimal coformer and the amount of coformer to add for a sp…
Electrical heating of the graphite die and punch assembly is a unique feature of the spark plasma sintering (SPS) process. The high currents needed to heat the die, despite its low resistance, can produce an electric field across the ceramic specimens that may be enough to induce field assisted sintering. Despite the…
We report on the preparation and characterization of magnetically oriented single-walled carbon nanotube arrangements as novel nanoprobes to enhance anisotropically water relaxation as detected by magnetic resonance imaging methods. SWCNT suspensions immobilized in agarose gels showed evident magnetic anisotropy with…
Ca and Mn co-doped BiFeO3 ultrafine nanofibres were prepared with the purpose of improving magnetic and photocatalytic performances of the one-dimensional multiferroic material. Impurity phase introduced by both Bi fluctuation and Mn substitution can be suppressed by Ca doping and a space group transition from R3c to…
We synthesized an amphiphilic fluorescent compound (PyAzEG) having a pyrene fluorophore directly attached to twisted ortho-alkylated azobenzene (i) to suppress pyrene excimer formation and (ii) to facilitate pyrene monomer fluorescence switching. PyAzEG molecules in a dilute solution underwent azobenzene-based trans ↔…
A new computational technique is presented for the investigation of multicomponent polymer phase behavior based on a Gibbs ensemble formulation of self-consistent field theory. Calculations in the Gibbs ensemble allow the simulation of two or more coexisting phases in the absence of an interface by enabling the exchan…
Human recombinant collagen can be cross-linked with a variety of chemical cross-linking agents. Cross-linking methods can be tuned to confer collagen-based scaffolds with specific physical properties, improved antigenicity and thermal stability without impeding the ability of the material to integrate into the surroun…

The ω-phase transformation and β-phase stability in Ti–xNb (28 ≤ x ≤ 40 at%) single crystals were investigated using electrical resistivity measurements, transmission electron microscopy (TEM) observations, and specific heat measurements. The crystal for x = 28 exhibits distinct anomalous negative temperature dependen…
Dielectric properties, polarization and x-ray diffraction are studied for (1-x)Na1/2Bi1/2TiO3-xBaTiO3 solid solutions in a concentration range above the morphotropic phase boundary. It is showed that all the studied compositions have tetragonal structure with maximal tetragonality slightly above the morphotropic phase…
Abstract The heterogeneous photocatalytic partial oxidation of cyclohexane in gas-phase as an alternative green process for fine chemicals synthesis was successfully achieved on Au/TiO
Bismuth ferrite, BiFeO3, is the most investigated multiferroic material in which ferroelectricity coexists with an antiferromagnetic order at room temperature. The crystalline structure of BiFeO3 is well recognized for monocrystals as well as for polycrystalline materials or thin films. BiFeO3 is reported to have a rh…
Ionically crosslinked chitosan membranes were prepared and their density was determined using modified pycnometer method. High‑molecular compound: sodium alginate (NaAlg) and low‑molecular compounds: pentasodium tripolyphosphate (TPP) and trisodium citrate (CIT) were used as ionic crosslinkers of chitosan. As a refere…
