hexagonal unit which form a unique 6c-4e o-bond to help stabilize the systems. The IR, Raman, UV-vis, and photoelectron spectra of the concerned species are computationally simulated to facilitate their experimental characterization.
A hybrid surfactant/polyoxometalate compound was synthesized by combining isopolytungstate anions with the cationic surfactant cetyltrimethylammonium bromide (CTA-Br) to produce a hierarchical compound that we identify as (CTA) <sub>7</sub> [H <sub>2</sub> W <sub>12</sub> O <sub>40</sub> ]Cl·2H <sub>2</sub> O.
The local structure around the mobile ions influences their dynamics.
Bent-core liquid crystals based on 1,2,4-oxadiazole as a central unit have been the first mesogens to exhibit a ferroelectric response in the nematic phase. This behavior has been widely recognized as due to the presence of smectic-like polar cybotactic clusters permeating the nematic phase. Unfortunately, these compo…
Multi-shape memory polymers were prepared by blending a series of styrene (St)-block-(styrene-random-meth acrylate (MA))-block-styrene triblock copolymer nano-latexes. These latexes synthesized using a reversible addition-fragmentation chain transfer (RAFT) emulsion polymerization method have a core-shell structure. T…
Gadolinium aluminate (GdAlO3) perovskite has been prepared from Gadolinium oxide and Aluminium nitrate by auto-igniting combustion process. Scanning electron micrographs also suggest polycrystalline microstructure with the grains of unequal size distributed throughout the pellet sample. Temperature and frequency depen…
Chemotherapy is a powerful cancer treatment but suffers from poor biocompatibility and a lack of tumor targeting. Here, we developed a CD44-targeted polymeric nanocomplex by encapsulating 10-hydroxycamptothecin (HCPT) into hyaluronic acid nanoparticles (HANP) for targeted cancer therapy. In vitro, the HANP/HCPT showed…
To systematically and comprehensively investigate the high voltage alternating electric field (HVAEF) thawing processing, we investigated the high-voltage electric field thawing characteristic of the frozen tofu at different voltages for alternating current (AC). The thawing time, thawing loss of frozen tofu, and spec…
The phase-change characteristics of Sn<sub>2</sub>Sb<sub>2</sub>Se<sub>5</sub>(SSS), a pseudo-binary chalcogenide material, were investigated for use in phase-change random access memory applications.
Non-isothermal magnetic studies can be used to estimate the activation energy of cooperative spin transition. Model-free isoconversional integral methods give reliable estimates of the activation barrier height for highly cooperative spin crossover systems with wide thermal hysteresis.
Warp-knitted spacer fabrics filled by rigid polyurethane foam within a reaction injection molding process offers a high potential for application as lightweight sandwich construction. For prediction of foam microstructure and finding appropriate process parameters the simulation of the propagation characteristics of P…
We report the synthesis of a new multifunctional nanomaterial based on silica-coated FePt/Fe 3 O 4 -CdSe heteronanostructures, combining luminescent and magnetic properties in a promising bifunctional sensor for biomedical applications. Spherical Fe 3 O 4 -coated FePt (FePt/Fe 3 O 4 ) superparamagnetic nanoparticles (…
Sr 0.7 R 0.3 CoO 3-δ (R = Tb and Er) tetragonal perovskites have been prepared and evaluated as mixed ionic-electronic cathodes for SOFC. Neutron powder diffraction (NPD) measurements evidenced that both compounds are oxygen hypo-stoichiometric with long-range order of oxygen vacancies that leads to a tetragonal perov…
Nanocomposites based on SBR with different content of manganous tungstate nanoparticles were prepared and characterized by FTIR, UV-visible spectroscopy, XRD, SEM, TGA, DSC and impedance analysis. The interaction between nanoparticles and the elastomer was clear from the shift in peaks of UV and FTIR. XRD and SEM anal…
As integrated circuits for high performance CMOS devices scale down to ≤ 10 nm dimension, further reductions in cap thickness to reduce capacitance are required for the Cu barrier while maintaining sufficient mechanical strength, low leakage, high dielectric breakdown, and fabrication integration robustness. This pape…
Synthesis and characterization of a liquid crystalline polymer with pendant copper phthalocyanine side chains ( <bold>PCuPc</bold> ).
A mixture of the bipyridine, phenyl and/or cyclohexanediamine-based building blocks 1, 2, and/or 3, having hydrazide, aldehyde or amine moieties, respectively, formed DMSO polymer gels by the hydrazone reaction under acidic conditions.
Microporous Co nanoparticles (NPs) with pore diameters of 0.38 nm have been prepared by dealloying Co–Al alloy NPs, which were subsequently annealed at different temperatures to synthesize microporous Co <sub>3</sub> O <sub>4</sub> –Co nanocomposites as electrode materials for pseudocapacitors.
A simple and controllable strategy to synthesize polymer ellipsoids <italic>via</italic> the viscosity-induced deformation of spherical particles is proposed.
Photo-induced processes in self-assembled coordination cages were studied by femtosecond infrared pump-probe spectroscopy. Densely packed, interpenetrated double cages were constructed from eight bis-monodentate redoxactive ligands bound to four Pd(ii) nodes. Two types of ligands consisting of electron rich phenothiaz…
