VIVoxyfluorides are of interest as frustrated magnets. The successful synthesis of two-dimensionally connected vanadium(IV) oxyfluoride structures generally requires the use of ionic liquids as solvents. During solvothermal synthesis experiments aimed at producing two- and three-dimensional vanadium(IV) selenites with triangular lattices, the title compound, diaquatetra-μ-fluorido-dioxidodivanadium(IV) monohydrate, V2O2F4(H2O)2·H2O, was discovered and features a new infinite V4+-containing two-dimensional layer comprised of fluorine-bridged corner- and edge-sharing VOF4(H2O) octahedral building units. The synthesis was carried out under solvothermal conditions. The V4+centre exhibits a typical off-centring, with a short V=O bond and an elongatedtrans-V—F bond. Hydrogen-bonded water molecules occur between the layers. The structure is related to previously reported vanadium oxyfluoride structures, in particular, the same layer topology is seen in VOF3.

Abstract In this paper, we investigate the design-evolution of an embedded pipe based on the constructal theory to obtain the best design that cools a square plate subjected to a constant heat flux boundary condition. The water, ionic liquids (ILs), and nano-enhanced ionic liquids (NEILs, i.e., [C4mim][NTf2] + Al2O3 and [C4mpyrr][NTf2] + Al2O3) have been used as the coolants. Several designs (Case 1 to Case 11) have been tested to quantify the non-dimensional temperature of the heated substrate by implementing the finite volume method of ansys fluent. The three-dimensional continuity, momentum, and energy equations have been solved iteratively in the fluid region by incorporating SIMPLE algorithm with appropriate boundary conditions; while the conduction equation is solved in the solid region. Among all the considered designs, it has been found that Case 3 provides a better cooling effect for the heated substrate. For all of the considered configurations/designs, it is also found that the non-dimensional temperature decreases with the length of the morphing pipe. NEILs exhibit a better cooling effect of the substrate when compared with the ILs and water. The present numerical methodology is also validated with the previous literature.

AbstractWe present an in silico characterization of the von Hippel-Lindau like protein (VLP), the only known human paralogue of the von Hippel-Lindau tumor suppressor protein (pVHL). Phylogenetic investigation showed VLP to be mostly conserved in upper mammals and specifically expressed in brain and testis. Structural analysis and molecular dynamics simulation show VLP to be very similar to pVHL three-dimensional organization and binding dynamics. In particular, conservation of elements at the protein interfaces suggests VLP to be a functional pVHL homolog potentially possessing multiple functions beyond HIF-1α-dependent binding activity. Our findings show that VLP may share at least seven interactors with pVHL, suggesting novel functional roles for this under-studied human protein. These may occur at precise hypoxia levels where functional overlap with pVHL may permit a finer modulation of pVHL functions.
