The Medium-Chain Dehydrogenase/Reductase Engineering Database (MDRED, http://www.mdred.uni-stuttgart.de) has been established to serve as an analysis tool for a systematic investigation of sequence-structure-function relationships. It includes sequence and structure information of 2684 and 42 medium-chain dehydrogenas…
This book is an update and major revision to Radiological Assessment: A Textbook on Environmental Dose Analysis published by the U.S. Nuclear Regulatory Commission in 1983. It focuses on risk to the public because decision makers typically use that endpoint to allocate resources and resolve issues. Chapters in the boo…
Abstract The long‐term thermal‐oxidative aging behavior of polyamide 6 (PA6) was studied by comparison with the stabilized sample in this work. The variation of mechanical properties of the pure and the stabilized samples of PA6 with aging time at 110°C, 130°C, and 150°C were investigated, respectively. The aging mech…
We report on how to tune the density of zinc oxide (ZnO) nanowire arrays in a wide range (more than 5 orders of magnitude) in a low temperature (80 °C) solution-phase growth process. A model based on the coexistence of nanowire growth and etching of the ultrathin (<3.5 nm) ZnO seed-layer was proposed to explain the ef…
Self-assembled monolayer-protected nanoparticles are promising candidates for applications, such as sensing and drug delivery, in which the molecular ligands' interactions with the surrounding environment play a crucial role. We recently showed that, when gold nanoparticles are coated with a binary mixture of immiscib…
Abstract Calcium alginate yarn (30 fibers) and calcium alginate nanocomposite yarn (30 fibers) containing 0.05–2.00% w/w chitin whiskers were both prepared by wet spinning process. The whiskers were prepared by acid hydrolysis of chitin from shrimp shells. The average length and width of the whiskers were 343 and 46 n…
Abstract For the miniaturization of microelectronics, carbon nanotubes (CNTs) are regarded as ideal candidates for the next generation of nanoelectronics because of their excellent properties. To realize CNT‐based electronics, intramolecular junctions are required components, which can not only connect different CNTs…
A phase-field approach for quantitative simulations of grain growth in anisotropic systems is introduced, together with a new methodology to derive appropriate model parameters that reproduce given misorientation and inclination dependent grain boundary energy and mobility in the simulations. The proposed model formul…
Two novel distyryl-boradiazaindacene dyes with dimethylaminostyryl and pyridylethenyl substituents display opposite spectral shifts on protonation with TFA in organic solvents. This bidirectional switching of the dyes can be shown to be directly related to ICT donor and acceptor characteristics of the substituents att…
We use first-principles methods to investigate the adsorption of Cu, Pb, Ag, and Mg onto a H-terminated Si surface. We show that Cu and Pb can adsorb strongly while Ag and Mg are fairly inert. In addition, two types of adsorption states are seen to exist for Pb. We also study the clustering energetics of Cu and Pb on…
Thin film growth of ferroelectric or multiferroic materials on SrTiO3(111) with a buffer electrode has been hampered by the difficulty of growing flat electrodes on this polar orientation. We report on the growth and characterization of SrRuO3 thin films deposited by pulsed laser deposition on SrTiO3(111). We show tha…
The phenomenological theory of ferroelectricity in spiral magnets presented in [M. Mostovoy, Phys. Rev. Lett. 96, 067601 (2006)] is generalized to describe consistently states with both uniform and modulated-in-space ferroelectric polarizations. A key point in this description is the symmetric part of the magnetoelect…
Responsive polymer microgels can be employed for the preparation of stimuli-sensitive emulsions. The microgels used in this study are based on cross-linked copolymers including N-isopropylacrylamide and methacrylic acid. We conducted the synthesis under acidic and basic conditions to investigate the effect of changes…
The materials used in rewritable CDs and DVDs also show promise as electronic memories systems.
Abstract Fiber length and distribution play important roles in the processing and mechanical performance of fiber‐based products such as paper and fiberboard. In the case of wood–plastic composites (WPC), the production of WPC with long fibers has been neglected, because they are difficult to handle with current produ…
Silicon carbide nanocrystals are water-soluble, chemically inert, and highly fluorescent, and they may be idealas biological labels. After the uptake of3C–SiC nanocrystals, human fetal osteoblast (hFOB) cells exhibit brightgreen–yellow fluorescence (see image).The nanoparticles show high resistanceagainst photobleachi…
We propose a simple and effective way to reduce the losses in left-handed metamaterials by manipulating the values of the effective parameters R, L, and C. We investigate the role of losses of the short-wire pairs and the fishnet structures. Increasing the effective inductance to capacitance ratio, L/C, reduces the lo…
This work is devoted to the analysis of the orbital ordering patterns and associated interatomic magnetic interactions in the centrosymmetric monoclinic structures of BiMnO 3 , which have been recently determined experimentally. First, we set up an effective lattice fermion model for the manganese 3d bands and derive…
The weakly interacting S=1/2 dimers system Sr3Cr2O8 has been investigated by powder neutron diffraction and inelastic neutron scattering. Our data reveal a structural phase transition below room temperature corresponding to an antiferro-orbital ordering with nearly 90 degrees arrangement of the occupied 3z^2-r^2 d-orb…
We report evidence for the first global-minimum structure having a planar pentacoordinate carbon. High-level ab initio computations and quantum molecular dynamics simulations at 300 and 400 K reveal that the most stable CAl5(+) isomer has D5h symmetry and is approximately 3.80 kcal/mol lower in energy than the second…
