This paper describes the developments, role and contributions of the NMR spectroscopy groups in the Structural Proteomics In Europe (SPINE) consortium. Focusing on the development of high-throughput (HTP) pipelines for NMR structure determinations of proteins, all aspects from sample preparation, data acquisition, dat…
The present study aims at contributing to a complete understanding of the water-induced ionic charge transport in cellulose. The behavior of this transport in loosely compacted microcrystalline cellulose (MCC) powder was investigated as a function of density utilizing a new type of measurement setup, allowing for diel…
X-ray diffraction experiments were performed to study the effect of forced solution flow on protein-crystal quality. The tetragonal crystals of hen egg white lysozyme were grown under flow in the rate range of 0 (quiescent condition) to 1000 μm/s. The quality of the crystals grown under flow was superior to that of cr…
Composites of polyaniline with nanocrystalline maghemite capped with oleic acid were synthesized at various maghemite loadings and their electrical and magnetic properties were studied from 5 to 300 K. Chemisorption of oleic acid by the surface iron atoms provided excellent dispersion of maghemite in organic solvents…
In this paper, we demonstrate the potential of chemical vapour transport and condensation in tuning the architecture of a series of MgO nanostructures through adjusting experimental parameters. Different oxygen partial pressures lead to corresponding well-faceted nanostructures, such as nanowires, cubes, orthogonally…
Lattice Boltzmann method (LBM) simulations of phonon transport are performed in one-dimensional (1D) and 2D computational models of a silicon-on-insulator transistor, in order to investigate its transient thermal response under Joule heating conditions, which cause a nonequilibrium region of high temperature known as…
Laboratory-scale experiments were performed in which the corrosion protection of stainless steels in seawater was afforded by cathodic protection. The method was implemented for the first time using the potential difference at the marine sediment/seawater interface as the only source of electric power. Graphite electr…
The linear and nonlinear optical polarizabilities of donor-acceptor (D-pi-A) chromophores in confined geometries of calix[4]arenes are investigated through a model for interacting polar-polarizable molecules. Both the linear polarizability (alpha) and the first hyperpolarizability (beta) decrease with increasing the i…
A detailed study is reported of the influence of protons, metal cations, and media on the redox chemistry of lacunary anions [alpha-SiW11O39]8- and [alpha-PW11O39]7- of high formal negative charge. Each anion displayed a single chemically reversible one-electron reduction process in carefully dried aprotic CH3CN solut…
Abstract Supramolecular chirality has been optically induced in an achiral epoxy‐based polymer containing photoresponsive azobenzene groups. The origin of this effect is the long‐range helical arrangement of the azobenzenes, which extends through the entire thickness of the film. The helicity induced by the handedness…
A low energy theory for nonlinear transport in finite-size single-wall carbon nanotubes, based on a microscopic model for the interacting ${p}_{z}$ electrons and successive bosonization, is presented. Due to the multiple degeneracy of the energy spectrum diagonal as well as off-diagonal (coherences) elements of the re…
A biosynthetic pathway is proposed for creating 6-deoxy-5-ketofructose-1-phosphate (DKFP), a precursor sugar for aromatic amino acid biosynthesis in Methanocaldococcus jannaschii. First, two possible routes were investigated to determine if a modified, established biosynthetic pathway could be responsible for generati…
The electronic level structure of colloidal InAs quantum dots (QDs) in two-dimensional arrays, forming a QD-solid system, was probed using scanning tunneling spectroscopy. The band gap is found to reduce compared to that of the corresponding isolated QDs. Typically, the electron (conduction-band) ground state red shif…
This paper reviews the developments in high-throughput and nanolitre-scale protein crystallography technologies within the remit of workpackage 4 of the Structural Proteomics In Europe (SPINE) project since the project's inception in October 2002. By surveying the uptake, use and experience of new technologies by SPIN…
Summary Chemical scale inhibitors are commonly used to prevent or inhibit scale formation in production. The most economic treatment of scale inhibitor is normally through chemical squeeze. However, there is little agreement regarding the primary mechanism by which the threshold scale inhibitors are retained in produc…
[reaction: see text] A novel type of "superbiaryl", the first porphyrin dimers with an intrinsically chiral structure, has been prepared. The atropo-enantiomers were configurationally assigned by HPLC-CD combined with quantum chemical CD calculations.
A procedure for the fabrication of nano-structured micropatterns by direct UV photo-patterning of a monolayer of a self-assembled block copolymer/transition metal hybrid structure is described. The method exploits the selective photochemical modification of a self-assembled monolayer of hexagonally ordered block copol…
An automatic data-collection system has been implemented and installed on seven insertion-device beamlines and a bending-magnet beamline at the ESRF (European Synchrotron Radiation Facility) as part of the SPINE (Structural Proteomics In Europe) development of an automated structure-determination pipeline. The system…
BACKGROUND: Percentage Identity (PID) is frequently quoted in discussion of sequence alignments since it appears simple and easy to understand. However, although there are several different ways to calculate percentage identity and each may yield a different result for the same alignment, the method of calculation is…
Protein characterization plays a role in two key aspects of structural proteomics. The first is the quality assessment of the produced protein preparations. Obtaining well diffracting crystals is one of the major bottlenecks in the structure-determination pipeline. Often, this is caused by the poor quality of the prot…
