Two different composite scaffolds, solid-freeform-fabricated PCL/β-TCP supplemented with and without collagen nanofibers are fabricated. These scaffolds are evaluated whether a combination of collagen nanofibers with PCL/β-TCP can promote osteogenesis in a mastoid obliteration. To assess the effects of the cellular ac…
Forme Dir Deinen Cluster: Zwei supramolekulare Cluster aus Lanthanoidhelicaten wurden synthetisiert. Die Clusterstruktur hängt von der Wahl des Anions ab: tetraedrisches ClO4− ergibt größere ringförmige Helicate, während trigonal-planares NO3− zu einem kompakten viersträngigen Helicat führt (siehe Bild).
The propagation characteristics of magnetostatic volume waves (MSVWs), namely, magnetostatic forward volume waves (MSFVWs) and magnetostatic backward volume waves (MSBVWs), in two-dimensional (2-D) magnonic crystals (MCs) with periodic thickness variation of square lattice in YIG layer are reported. The theoretical ap…
The effects of aluminum nanoparticles (AlNs) on the thermal decomposition of ammonia perchlorate (AP) were investigated by DSC, TG-DSC and DSC-TG-MS-FTIR. Addition of AlNs resulted in an increase in the temperature of the first exothermic peak of AP and a decrease in the second. The processing of non-isothermal data a…
Molecules constructed from a combination of zero-dimensional ([60]fullerene (C60)) and two-dimensional (porphyrin (Por)) nanobuilding blocks represent an intriguing category of sphere-square "shape amphiphiles". These sphere-square shape amphiphiles possess interesting optoelectronic properties. To efficiently synthes…
BACKGROUND: Two species of wild silkworms, the Chinese oak silkworm (Antheraea pernyi) and the castor silkworm Philosamia cynthia ricini, can acquire a serious disease caused by Nucleopolyhedrin Viruses (NPVs) (known as AnpeNPV and PhcyNPV, respectively). The two viruses have similar polyhedral morphologies and their…
In order to determine an accurate equilibrium structure for 1,3,4-oxadiazole, microwave transitions and ground-state rotational constants are reported for the parent species and for the (18)O isotopologue measured in natural abundance. These rotational constants along with those of the (13)C, (15)N, and D1 species wer…
A new ditopic pyrimidine-hydrazone ligand, 6-hydroxymethylacryloyl-2-pyridinecarboxaldehyde, 2,2'-[2,2'-(2-methyl-4,6-pyrimidinediyl)bis(1-methylhydrazone)] (L2), was synthesized with terminal acryloyl functional groups to allow incorporation into copolymer gel actuators. NMR spectroscopy was used to show that L2 adop…
Abstract Recent attention has been given to the realization of angular deficits and surpluses in the local ground-state geometry of thin sheets of nematic solids as out-of-plane deformations. Such systems exhibit conical or anti-conical curvature sites, or possibly arrays of such polyhedral corners, in order to satisf…

The electronic structure and magnetic properties of atomic sulfur and oxygen adsorbed on the iron (001) surface are examined using density functional theory (DFT). The sulfur/oxygen coverage is considered from a quarter of one monolayer (ML) to a full monolayer. The work function change, magnetic properties, and densi…
The competing spin orders and fractional magnetization plateaus of the classical Heisenberg model with long-range interactions on a Shastry-Sutherland lattice are investigated using Monte Carlo simulations, in order to understand the fascinating spin ordering sequence observed in TmB4 and other rare-earth tetraborides…
A range of novel octahedral iron(IV)-nitrido complexes with the TMC ligand (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) in the equatorial plane and one axial ligand trans to the nitrido have been designed theoretically, and a systematic comparative study of their geometries, electronic properties, an…
The interaction of ligands and drug molecules with protein is of major interest in drug pharmacokinetics and pharmacodynamics. In this study, we synthesized a novel thiosemicarbazone-based amphiphilic molecule for selective binding and detection of human serum albumin (HSA) with significant increase in fluorescence in…
The energetics and dynamics of the various phases of decanethiolate self-assembled monolayers on Au(111) surfaces were studied with scanning tunneling microscopy. We have observed five different phases of the decanethiolate monolayer on Au(111): four ordered phases (β, δ, χ*, and φ) and one disordered phase (ε). We ha…
We report the electronic and magnetic phase diagram of Ca${}_{3}$(Ru${}_{1\ensuremath{-}x}$Ti${}_{x}$)${}_{2}$O${}_{7}$. With Ti doping, the system evolves from a quasi-two-dimensional metal with ferromagnetic (FM) bilayers coupled antiferromagnetically along the $c$ axis (AFM-b) for $x=0$, to a weakly localized state…
Herein, we describe the first report on a new class of disk-shaped and quite monodisperse water-soluble nanomaterials that we named glyconanosomes (GNS). GNSs were obtained by sliding out the cylindrical structures formed upon self-organization and photopolymerization of glycolipid 1 on single-walled carbon nanotube (…
Catching the sunlight: The disordered Co1.28Mn1.71O4 was synthesized by a facile reduction method in the presence of amorphous MnO2 precursors and Co(2+). It exhibits relatively high hydrogen-production activity under visible-light irradiation (see figure). The larger number of active sites in the bulk catalyst endow…
We have investigated the (001) surface structure of lithium titanate (Li 2 TiO 3 ) using auger electron spectroscopy (AES), low-energy electron diffraction (LEED), and scanning tunneling microscopy (STM). Li 2 TiO 3 is a potential fusion reactor blanket material. After annealing at 1200 K, LEED demonstrated that the L…
Catalytic propane dehydrogenation has been tested on different reactor configurations employing Pt–Sn/MgAl 2 O 4 as a catalyst. Hollow fiber palladium membranes coupled to the two-zone fluidized bed reactor (TZFBR) combine the possibility of improving propane conversion by hydrogen removal from the reaction bed throug…
