The X-ray diffractions of cobalt nanoparticles synthesized by a microfluidic reactor process at low temperature suggest glasslike phases with only one broad peak. An X-ray absorption fine-structure (XAFS) technique is used to investigate fine crystal phase transition or changes in atomic arrangement and interatom spac…
The phase transition characteristics and device performance of Si-doped Ge 2 Sb 2 Te 5 thin films were studied for PRAM application. Si-doped Ge 2 Sb 2 Te 5 thin films were deposited by the RF-magnetron cosputtering system and phase transition characteristics were analyzed by x-ray diffractometer (XRD), 4-point probe…
We demonstrate strong evidence of shape-dependent efficient resonance energy transfer between CdS quantum dots (QDs) and quantum rods (QRs) (donor) to Nile Red dye (acceptor). We also report a simple solution-based method for the preparation of high quality CdS QDs and CdS QRs at relatively low temperature. The observ…
Acoustic emission (AE) signals generated by transgranular stress corrosion cracking (TGSCC) and intergranular stress corrosion cracking (IGSCC) have been compared by means of slow strain rate tensile tests (SSRT) performed using both solubilised and sensitised type AISI 304 stainless steel in a 1 M NaCl + 1 M HCl solu…
The excellent structural and optical properties of pseudomorphic Mg x Zn 1- x O films (0≤ x ≤0.39) are reported in this work. The Mg x Zn 1- x O films were grown on Zn-polar ZnO substrates by plasma-assisted molecular beam epitaxy. Those Mg x Zn 1- x O films for which x ≤0.18 exhibited atomically flat surfaces, and th…
The hydrolytic stability and the effect of annealing on the improved aging properties of self-assembled monolayer (SAM) hydrophobic coatings have been investigated. Surfaces coated with hydrophobic SAM coatings give higher flow rate and are of wide interest to researchers in the area of microfluidics. Hydrophobic SAM…

One of the major challenges in the postgenomic era is the functional assignment of proteins using sequence- and structure-based predictive methods coupled with experimental validation. We have used these approaches to investigate the structure and function of the Escherichia coli K-12 protein YfaU, annotated as a puta…
A growth mechanism for single crystalline hollow spheres was proposed based on the study of the formation process of single crystalline Cu 2 O multishelled hollow spheres. On the basis of transmission electron microscopy, high resolution transmission electron microscopy, selected area electron diffraction analysis of…
A rapid chemical method has been developed for the synthesis of the Ag 2 Te nanorods with monoclinic crystalline phase. The method is based on the template-engaged synthesis in which the Te nanorods were used as template reagents. On the basis of a series of experiments and characterizations, the effect factors and th…
Niedriger Schmelzpunkt – hohe Lumineszenz: [C3mim][Eu(Tf2N)4] (1), [C4mim][Eu(Tf2N)4] und [C4mpyr]2[Eu(Tf2N)5] sind die ersten Ln-basierten ionischen Flüssigkeiten, die keine Stabilisierung durch neutrale Coliganden erfordern. Sie zeigen exzellente photophysikalische Eigenschaften, wie lange Lebensdauer der Lumineszen…
Bioreactors are widely used in tissue engineering as a way to distribute nutrients within porous materials and provide physical stimulus required by many tissues. However, the fluid dynamics within the large porous structure are not well understood. In this study, we explored the effect of reactor geometry by using re…
The l-rhamnonate dehydratase (RhamD) function was assigned to a previously uncharacterized family in the mechanistically diverse enolase superfamily that is encoded by the genome of Escherichia coli K-12. We screened a library of acid sugars to discover that the enzyme displays a promiscuous substrate specificity: l-r…
The experimental (100 K) and theoretical charge densities in the binuclear complexes [Cu2(ap)2(L)2] (ap = 3-aminopropanolate) 1 (L = nitrite), 2 (L = nitrate), and 3 (L = formate) have been examined. These complexes contain the same centrosymmetric alkoxy-bridged motif, where each strongly Jahn-Teller distorted Cu(II)…
By means of a plasma technique, the surfaces of monodisperse polystyrene (PS) colloids have been modified with hydroxyl groups. Using these surface-modified PS colloids as sacrificial templates, we have fabricated silica-coated PS colloids (PS@silica) and titania-coated PS colloids (PS@titania) composite microspheres…
Abstract In a follow‐up study of the cobalt(II) member 1 of a family of isostructural cubane clusters of type [C(NH 2 ) 3 ] 8 [M II 4 (cit) 4 ]·8H 2 O (cit = citrate, M = Mg, Mn, Fe, Co, Ni, Zn) by measuring AC magnetic susceptibilities, as a function of frequency, this compound clearly displays behaviour typical of m…
In this research wood-plastic composite (WPC) panels were produced from high density polyethylene, MDF, and particle-board waste at 60, 70, and 80 wt% fiber loadings using the dry blend/hot press method. Physical and mechanical properties of the panels were studied and compared with conventional MDF and particle-board…
Convection-enhanced delivery (CED) with various drug carrier systems has recently emerged as a novel chemotherapeutic method to overcome the problems of current chemotherapies against brain tumors. Polymeric micelle systems have exhibited dramatically higher in vivo antitumor activity in systemic administration. This…
This paper presents an aqueous route to size-controlled and doped CeO 2 nanoparticles using the Ce-oleate complex as a chemically modified precursor. In this synthesis, a hydrolytic condensation of Ce-oleate complex by aqueous ammonia solution at room temperature leads to 2.2 nm sized CeO 2 nanocrystals. These product…
The creation of Néel domain walls by electric fields in conventional and weak ferromagnets is discussed. In an inhomogeneous electric field the walls move with velocity proportional to the field gradient.
