Double emulsions are valuable for the formation of multi-compartmental structures. A variety of pathways to prepare double emulsions have been developed, but high-throughput routes to droplets of controlled size and architecture remain scarce. A new single-step process is introduced for preparation of water-in-oil-in-…
Enhancing the device performance of single crystal organic field effect transistors (OFETs) requires both optimized engineering of efficient injection of the carriers through the contact and improvement of the dielectric interface for reduction of traps and scattering centers. Since the accumulation and flow of charge…
Corrosion performance of austenitic-ferritic (duplex) stainless steels UNS S32101, S32202, S32304, and S32205 and austenitic stainless steels UNS S30403 and S31603 was studied in the presence of chloride deposits simulating non-rinsing atmospheric conditions. The effect of temperature, relative humidity, concentration…
Correlation between thermal hysteresis width and broadening of metal–insulator transition in Cr- and Nb-doped VO2 films, Miyazaki, Kenichi, Shibuya, Keisuke, Suzuki, Megumi, Wado, Hiroyuki, Sawa, Akihito
Gordonia polyisoprenivorans strain VH2, a potent rubber-degrading actinomycete, harbors two latex clearing proteins (Lcps), which are known to be essential for the microbial degradation of rubber. However, biochemical information on the exact role of this protein in the degradation of polyisoprene was lacking. In this…
Fully biobased saturated and unsaturated aliphatic polyesters and oligoesters are successfully prepared by Candida antarctica lipase B (CALB)‐catalyzed polycondensations of succinate, itaconate, and 1,4‐butanediol. The effects of monomer substrates and polymerization methods on enzymatic polycondensation are investiga…
In this paper, procedures and parameters that enable identification of, or discrimination between, general and localized corrosion processes through electrochemical noise are critically discussed. Their relevant similarities, differences, and interdependences are indicated. In addition, the relation between different…
In this study, we present a method for determining the relative affinity of nanoparticles (NPs) for an ensemble of other particles in a complex, heterogeneous suspension. We evaluated this method for NPs heteroaggregating with suspended solids present in activated sludge. A relationship was derived between the heterog…
The bipolar fatigue behavior of (K,Na)NbO3 (KNN)-based lead-free piezoceramics was investigated. A comparative analysis demonstrated that CaZrO3-modified KNN ceramics exhibited highly enhanced bipolar fatigue resistance due to the reduced lattice distortion (c/a ratio) and coexistence of orthorhombic and tetragonal ph…
Here we report the magnetic properties of Fe doped TiO2 nanoparticles annealed in air and vacuum. Fe doped TiO2 nanoparticles display paramagnetism during air annealing and ferromagnetism when the samples are annealed under vacuum. Ferromagnetism in vacuum annealed pure TiO2 nanoparticles is because of the presence of…
In this work, photovoltachromic cells (PVCCs) are fabricated using a solvent-free polyethylene glycol (PEG)-titanium hybrid polymer electrolyte. With appropriate addition of 1,2-dimethyl-3-propylimidazolium iodide in the electrolyte, the range of tunable colored-state transmittance of the PVCC is enlarged due to an im…
Gas turbine engines (GTE) are widely applied in the ship propulsion complexes. Although GTE have many technical advantages, but for the wider application in shipbuilding it is necessary to carry out one of the most important requirements that nowadays is actual for all power-engineering objects — to increase efficienc…
Three-dimensional heterogeneously nanostructured thin-film electrodes were fabricated by using Ta2O5 nanotubes as a framework to support carbon-onion-coated Fe2O3 nanoparticles along the surface of the nanotubes. Carbon onion layers function as microelectrodes to separate the two different metal oxides and form a nano…
The precise placement and efficient deposition of semiconducting single-walled carbon nanotubes (sc-SWCNTs) on substrates are challenges for achieving printed high-performance SWCNT thin-film transistors (TFTs) with independent gates. It was found that the wettability of the substrate played a key role in the electric…
Density functional theory and its time-dependent extension (DFT, TDDFT) has been herein employed to elucidate the structural and electronic properties for a series of isoindole-boron dipyrromethene (isoindole-BODIPY) derivatives. The role played by both the nature and the positions of the substituents on intersystem s…
Water was used to replace the toxic organic solvent of formamide in preparation of the aqueous dispersions of layered double hydroxide/polyacrylamide (LDH/PAM) nanocomposites, which exhibited greatly enhanced rheological properties when compared to those of the neat PAM. First, the nanocomposite dispersions were prepa…
The new chiral Binap-based fluorinated dialcohol proteo-ligand {ONNO}H 2 has been prepared under its enantiomerically pure and racemic forms following reaction of ( R )- or ( rac )-1,1′-binaphthyl-2,2′-diamine with 5,5,5-trifluoro-4-hydroxy-4-(trifluoromethyl)pentan-2-one. The racemic proteo-ligand reacts with the tri…
In this article, we disclose a method to fabricate polymer-stabilised azo-dye photo alignment layers for liquid crystal. The idea includes the introduction of polymer network in the alignment layer, in optimal concentration, followed by two-step irradiation. The stabilised photo-alignment layer has been explored for d…
Semiconducting polymer dots (Pdots) represent a new class of fluorescent nanoparticles for biological applications. In this study, we investigated their size-dependent fluorescence and cellular labeling properties. We demonstrate that the polymer conformation in solution phase largely affects the polymer folding and p…
This study reports a smart controlled drug release system based on mesoporous silica nanoparticles (MSNs) for targeted drug delivery. The system was fabricated by employing heparin as an end-capping agent to seal the mesopores of MSNs via disulfide bonds as intermediate linkers for intracellular glutathione triggered…
