Selected carbon-rich refinery residues ('binders') mixed with mineral particles can form composite materials ('bituminous concrete') with bulk mechanical properties comparable to those of cement concrete. The microstructural mechanism underlying the remarkable composite properties has been related to the appearance of a rigid percolating network consisting of asphaltenes and mineral particles [...

Catalysts based on functionalised carbon nanofibers (FCNF) coated with Ni-decorated MoS2 nanosheets were obtained by direct decomposition of ammonium thiomolybdate and nickel nitrate impregnated on the FCNF under controlled temperature conditions in inert atmosphere. The catalysts were characterised by X-ray Diffraction (XRD), N2 adsorption, Raman spectroscopy, temperature programmed reduction ...

The boundaries of liquid and vapor coexistence fields at pressures 101.3 0.133 kPa were calculated based on the partial pressure values components in Al-Al2Se3 Al2Se3-Se systems. more volatile aluminum selenide selenium above systems determined by isothermal version boiling-point method. fewer numerical integration Gibbs–Duhem equation. integral thermodynamic functions formation evaporation sol...

Pathogenic bacteria secrete pore-forming toxins (PFTs) to attack target cells. PFTs are expressed as water-soluble monomeric proteins, which oligomerize into nonlytic prepore intermediates on the target cell membrane before forming membrane-spanning pores. Despite a wealth of biochemical data, the lack of high-resolution prepore structural information has hampered understanding of the β-barrel ...

Laminins regulate diverse cellular functions through interaction with integrins. Two regions of laminins—three laminin globular domains of the a chain (LG1–3) and the carboxyl-terminal tail of the g chain (g-tail)—are required for integrin binding, but it remains unclear how the g-tail contributes to the binding. We determined the crystal structure of the integrin binding fragment of laminin-51...

Laminins regulate diverse cellular functions through interaction with integrins. Two regions of laminins-three laminin globular domains of the α chain (LG1-3) and the carboxyl-terminal tail of the γ chain (γ-tail)-are required for integrin binding, but it remains unclear how the γ-tail contributes to the binding. We determined the crystal structure of the integrin binding fragment of laminin-51...

The WD-repeat domain is a highly conserved recognition module in eukaryotes involved in diverse cellular processes. It is still not well understood how the bottom of a WD-repeat domain recognizes its binding partners. The WD-repeat-containing protein EED is one component of the PRC2 complex that possesses histone methyltransferase activity required for gene repression. Here we report the crysta...

We calculate the 0 order in opacity number distribution of massive photons (gluons) for heavy quark production radiation including interference from the away-side jet. While consistent with the soft photon (gluon) approximation, we find that taking 1−x ≈ 1, as done in previous calculations, strongly affects the magnitude of energy loss. Restoring gauge invariance by including the radiation asso...

Two-dimensional surface structures formed by organic self-assembly offer an efficient route to bottom-up assembly of tailored nanostructures. Organic building blocks are especially interesting because of the wide variety of structures and properties that can be "built-in" at the synthesis stage. Well-controlled studies of these systems under ultrahigh vacuum conditions allow a careful look at t...

Hydrogenated nanocrystalline silicon obtained by Hot-Wire Chemical Vapour Deposition has been incorporated as the active layer in bottom-gate thin-film transistors. These devices were electrically characterised by measuring in vacuum the output and transfer characteristics for different temperatures. The field-effect mobility showed a thermally activated behaviour which could be attributed to p...
