The measured thermodynamic phase diagram of the quasi-two-dimensional magnet $[\text{Cu}({\text{HF}}_{2}){(\text{pyz})}_{2}]{\text{BF}}_{4}(\text{pyz}=\text{pyrazine}={\text{N}}_{2}{\text{C}}_{4}{\text{H}}_{4})$ exhibits an unusual nonmonotonic dependence of the N\'eel temperature ${T}_{N}$ as a function of magnetic f…
Kinetics of spreading of aqueous trisiloxane surfactant T(n) (with n = 4, 6, and 8 ethoxy groups) solutions and conventional aqueous surfactant solutions (Tween 20, C12E4, SDS) over silicon wafers coated with PTFE AF is experimentally investigated. It has been found that trisiloxane solutions spread on highly hydropho…
Abstract We have demonstrated a general template synthesis halloysite‐based composite nanotube. Starting from a parent halloysite nanotube, polymer composite nanotubes were synthesized by atom transfer radical polymerization (ATRP). The shell thickness and the cavity size of the polymer composite nanotubes were tunabl…
We investigate the effects of particle size and shape on the quadrupolar (Saturn-ring-like) defect structures formed by a nematic liquid crystal around nm-sized and mum -sized particles with spherical and spherocylindrical shapes. We also report results for the potentials of mean force in our systems, calculated using…
Stable ZnO nanoparticles suitable for further surface functionalization were synthesized in the liquid phase from homogeneous ethanolic solutions of the precursors lithium hydroxide and zinc acetate. It was found that the growth of the particles was governed by temperature as well as the presence of the reaction bypro…
The Rayleigh–Taylor instability of two immiscible fluids in the limit of small Atwood numbers is studied by means of a phase-field description. In this method, the sharp fluid interface is replaced by a thin, yet finite, transition layer where the interfacial forces vary smoothly. This is achieved by introducing an or…
An effective and facile approach to prepare gold-nanoparticle-encapsulated alginic acid-poly[2-(diethylamino)ethyl methacrylate] monodisperse hybrid nanospheres (ALG-PDEA-Au) is developed by using monodisperse ALG-PDEA nanospheres as a precursor nanoparticulate reaction system. This approach utilizes particle-interior…
Experimental studies of the surface morphology and electronic structure of bulk single crystals of the transparent and wide gap semiconductor gallium oxide (β-Ga2O3) have been conducted using scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), and angle-resolved photoemission spectroscopy (ARP…
In this study, the association ("electrostatic self-assembly") of cationic generation 4 poly(amidoamine) dendrimer with a set of oppositely charged aromatic and aliphatic organic sulfonate counterions was investigated. Aggregate size and shape depend on the counterion structure. Formation of defined assemblies was pos…
Abstract Network (sponge) and cellular structures are often seen in various types of materials. Materials with such structures are generally characterized by light weight and high mechanical strength. The usefulness of such materials is highlighted, for example, by the remarkable material properties of bone tissue, wh…
To overcome shortcomings of current small-diameter vascular prostheses, we developed a novel allogenic vascular graft from a decellularized scaffold modified through heparin immobilization and vascular endothelial growth factor (VEGF) coating. The VEGF coating and release profiles were assayed by enzyme-linked immunos…
A generalized approach to attain spinnability in polymer solutions in electrospinning using emulsions is described. By using emulsions, low-molecular weight (MW) polymer solutions that tend to electrospray can be spun into nanofibers. Additionally, control over fiber properties independent of polymer solution viscosit…
The catalytic activities of ruthenium-based catalysts (5 wt% Ru) supported on alumina, ceria and ceria/alumina with different proportions of ceria ( n Ce10Al, n = 1, 3, 5; n = atomic ratio) were studied for the methane reforming reaction with CO 2 (CH 4 /CO 2 = 1) in the temperature range of 400–800 °C. Evaluation of…
We report on investigations on the atomic dynamics and the static structure factors of binary ${\text{Ni}}_{36}{\text{Zr}}_{64}$ alloy melts. In order to undercool the melts deeply below the melting temperature and to avoid reactions with crucible materials, the liquids are containerlessly processed by the application…
Room temperature spontaneous magnetization and dielectric anomaly at Néel temperature are observed in 15% Eu doped bismuth ferrite indicating the multiferroic nature of the sample. With 15% Eu doping structural transformation from rhombohedral to triclinic is observed. Fe3+ and Eu3+ oxidation states are observed from…
We introduce a new dynamic light scattering method, termed photon correlation imaging, which enables us to resolve the dynamics of soft matter in space and time. We demonstrate photon correlation imaging by investigating the slow dynamics of a quasi-two-dimensional coarsening foam made of highly packed, deformable bub…
Abstract Polycrystalline ceramic/single‐walled carbon nanotube (SWNT) composites possess unique grain boundaries, containing 1D tortuous SWNTs bundles that form 2D tangled embedded nets. This unprecedented grain‐boundary structure allows tailoring of multifunctional ceramic/SWNTs composites with unique combinations of…
LiBH 4 exhibits lithium superionic conduction accompanied by structural transition at around 390 K. Addition of LiCl to LiBH4 drastically affects both the transition and electrical conductivity: Transition from low-temperature (LT) to high-temperature (HT) phases in LiBH4 is observed at 370 K upon heating and the HT p…
An infinite-layer-structure epitaxial thin film of LaNiO2 was prepared by low-temperature reduction with CaH2 from a LaNiO3 epitaxial thin film grown on a SrTiO3(100) substrate. The oxygen content changed reversibly from the perovskite LaNiO3 to the infinite-layer LaNiO2 without losing the structural framework and the…
We have measured the infrared properties of optically transparent and electrically conductive single walled carbon nanotube thin films. We found that nanotube films with sheet resistance values of 200 Ω/sq show outstanding transmittance in the infrared range up to at least 22 μm, with an average transmittance greater…
