Semiconducting two-dimensional transition metal dichalcogenides are emerging as top candidates for post-silicon electronics. While most of them exhibit isotropic behaviour, lowering the lattice symmetry could induce anisotropic properties, which are both scientifically interesting and potentially useful. Here we present atomically thin rhenium disulfide (ReS2) flakes with unique distorted 1T st...

Massively parallel sequencing instruments enable rapid and inexpensive DNA sequence data production. Because these instruments are new, their data require characterization with respect to accuracy and utility. To address this, we sequenced a Caernohabditis elegans N2 Bristol strain isolate using the Solexa Sequence Analyzer, and compared the reads to the reference genome to characterize the dat...

Rhinophyma is a condition that can cause significant disfigurement as well as functional impairment of the nose. It results from hypertrophy and hyperplasia of the sebaceous glands and can be a manifestation of advanced staged rosacea. If left untreated, not only can it cause disfigurement, rhinophyma can also result in nasal airway obstruction by marked ptosis and collapse of the external nasa...

Molybdenite is the major source of Re in the Earth’s crust. Mineralogical data, chemical analyses and  scanning electron microscopy techniques have been used in this study to document Re behavior in molybdenite, affected by hypogene and near-surface processes. XRD study of  molybdenite samples indicate that the molybdenites are of the 2H polytype.The patterns of rhenium distribution in molybden...

The first synthesis of a CF3-substituted semisquarate was accomplished via nucleophilic trifluoromethylation using CF3SiMe3 and subsequent rhenium-catalyzed allylic alcohol rearrangement. The short-step skeletal-divergent synthesis of trifluoromethylated functional molecules was successfully achieved using the CF3-substituted semisquarate as the platform.

Theoretical studies on the hypoelectronic metalladicarbaboranes CpMC(2)B(n-3)H(n-1) (M = Mn, Re; n = 9, 10, 11) having 2n skeletal electrons indicate that true isocloso MC(2)B(n-3) deltahedra are highly energetically favored in which the metal atom occupies the single degree 6 vertex. This contrasts with the previously studied isoelectronic diferradicarbaboranes Cp(2)Fe(2)C(2)B(n-3)H(n-1) for w...

Rhenium complex []Cl with the coordinated [11]ane-P(2)C(NHC) macrocycle was obtained by a metal template controlled ring formation reaction; in this reaction a coordinated NH,NH-stabilised imidazolidin-2-ylidene ligand was connected via the nitrogen atoms to two phenyl substituents of a 2-fluorophenyl substituted diphosphine ligand.

To understand the aqueous species important for transport of rhenium under supercritical conditions, we conducted a series of solubility experiments on the Re–ReO2 buffer assemblage and ReS2. In these experiments, pH was buffered by the K–feldspar–muscovite–quartz assemblage; fO2 in sulfur-free systems was buffered by the Re–ReO2 assemblage; and fO2 and fS2 in sulfur-containing systems were buf...
