Joints permit efficient locomotion, especially among animals with a rigid skeleton. Joint morphologies vary in the body of individual animals, and the shapes of homologous joints often differ across species. The diverse locomotive behaviors of animals are based, in part, on the developmental and evolutionary history o…
Abstract The morphology, tensile, impact properties, and thermal expansion behavior of polycarbonate (PC)/acrylonitrile‐styrene‐butadiene (ABS)/talc composites with different compositions and mixing sequences were investigated. From the studies of morphology of the PC/ABS/talc composites, it was observed that some tal…
We report on the first synthesis and structural characterizations of a new Erbium (Er) compound, the erbium chloride silicate (ECS, Er3Cl(SiO4)2) single crystal in a Si-ECS core-shell nanowire form. The Er-concentration in ECS at 1.6x1022 cm−3 is three orders of magnitude higher than that of the Er-doped materials. Ph…
In the present study, fiber‐matrix compatibility in an all‐oxide ceramic composite is examined. Reaction‐bonding aluminum oxide is used as porous matrix to ensure weak interfaces with fibers. Matrix cracks have been deflected around the interface for sintering temperatures up to 1300°C, due to the effectiveness of por…
Abstract Some plant oil derived cyclohexane tricarboxylic acid triesters were synthesized and suggested as potential plasticizers based mainly on renewable feedstock. Methyl calendulate 1 and α‐eleostearate 2 obtained from calendula oil and tung oil, respectively, as well as methyl oleate 3 were used as starting mater…
We report an efficient triplet state self-quenching mechanism in crystals of eight benzophenones, which included the parent structure (1), six 4,4'-disubstituted compounds with NH(2) (2), NMe(2) (3), OH (4), OMe (5), COOH (6), and COOMe (7), and benzophenone-3,3',4,4'-tetracarboxylic dianhydride (8). Self-quenching ef…
Supercapacitors represent an attractive alternative for portable electronics and automotive applications due to their high specific power, and extended lifetime. The poly (3, 4-ethylenedioxythiophene) (PEDOT) and polythiophene (PTh) have attracted much attention because of their excellent environmental stability, opti…
A photoinduced spin-state change in the itinerant correlated electron system is studied. A photon introduced in the low-spin band insulator induces a bound state of the high-spin state and a photoexcited hole. This bound state brings a characteristic peak in the pump-probe optical absorption spectra which are complete…
Abstract The waterborne polyurethane (PU) prepolymer was first prepared based on isophorone diisocyanate, polyether polyol (NJ‐210), dimethylol propionic acid (DMPA), and hydroxyethyl methyl acrylate via in situ method. The crosslinked waterborne polyurethane‐acrylate (PUA) dispersions were prepared with the different…
Two Schiff bases were synthesized by reaction of 2-(4'-aminophenyl)benzoxazole derivatives with 4-N,N-diethylaminobenzaldehyde. UV-visible (UV-vis) and steady-state fluorescence in solution were applied in order to characterize its photophysical behavior. The Schiff bases present absorption in the UV region with fluor…
Our previous work has demonstrated that the cellulose solution dissolved in 7 wt % NaOH/12 wt % urea aqueous system precooled to -12 °C was metastable. It is worth noting that light scattering investigation on the cellulose solution at metastable state is difficult. In the present paper, the solution properties and dy…
A two-tiered Ag nanoparticle containing a cavity at the center of each nanoparticle is generated by two simple steps of nano-imprinting and metal vacuum deposition. It enables sub-zeptomole detection of organic molecules and five orders of the dynamic sensing range.
We investigate the effects of the $\sqrt{5}\ifmmode\times\else\texttimes\fi{}\sqrt{5}$ Fe vacancy ordering on the orbital and magnetic order in (K,Tl,Cs)${}_{y}$Fe${}_{2\ensuremath{-}x}$Se${}_{2}$ using a three-orbital (${t}_{2g}$) tight-binding Hamiltonian with generalized Hubbard interactions. We find that vacancy o…
RuCo films have been grown by plasma enhanced atomic layer deposition (PEALD) and investigated as a novel direct plate liner for advanced copper metallization. The RuCo films were characterized by transmission electron microscope (TEM) and found to form solid solutions, unlike other PEALD-grown mixed-phase direct plat…
Although knowledge about carbon hybrid films comprising both sp 2 and sp 3 bonding structures is of great importance for innovation applications of diamond-based nanostructures, little is known about the mixed hybridization forms in the same two-dimensional material. In this study, the structural properties of two-dim…
Binary water mixtures usually display a water relaxation (process II) which can be studied by broadband dielectric spectroscopy (BDS) at subzero temperatures. In a large collection of binary water mixtures, a slight increase of the relaxation strength is observed for low water concentration, whereas a faster increase…
Silicon-rich silicon nitride (SiNX) films have attracted enormous interests due to their promising luminescence properties and well compatibility with current CMOS technique. In this short review, the fabrication process of SiNX was addressed as well as their chemical composition and structure. The optical properties…
We propose a theoretical description of the phase diagram and physical properties in A(2)Fe(4)Se(5)-type (A=K, Tl) compounds based on a coexistent local moment and itinerant electron picture. Using neutron scattering and angle-resolved photoemission spectroscopy measurements to fix the general structure of the local m…
Abstract A novel macroporous poly(glycidyl methacrylate‐triallyl isocyanurate‐ethyleneglycol dimethacrylate) copolymer, hereinafter P GMA‐TAIC‐EGDMA , of controlled bead size was prepared via free radical suspension copolymerization. The effects of varying the concentration of crosslinking agents and porogenic diluent…
Polymeric bicontinuous microemulsions (BμE) are unique disordered morphologies found in well-designed ternary blends of two immiscible homopolymers and a diblock copolymer surfactant. By crystallization or vitrification of one component and selective extraction of another, polymeric BμEs are efficient precursors to na…
