For 2006, the consumption is given as 28% for General Electric, 28% Rolls-Royce plc and 12% Pratt & Whitney, all for superalloys, whereas the use for catalysts only accounts for 14% and the remaining applications use 18%.[42] In 2006, 77% of the rhenium consumption in the United States was in alloys.[43] The rising demand for military jet engines and the constant supply made it necessary to develop superalloys with a lower rhenium content. For example, the newer CFM International CFM56 high-pressure turbine (HPT) blades will use Rene N515 with a rhenium content of 1.5% instead of Rene N5 with 3%.[50][51]. Rhenium improves the properties of tungsten. Tungsten-rhenium alloys are more ductile at low temperature, allowing them to be more easily machined. The high-temperature stability is also improved. The effect increases with the rhenium concentration, and therefore tungsten alloys are produced with up to 27% of Re, which is the solubility limit.[52] Tungsten-rhenium wire was originally created in ...

The syntheses of two chromophore-appended dipicolylamine-derived ligands and their reactivity with pentacarbonylchlororhenium have been studied. The resultant complexes each possess the fac-Re(CO)3 core. The ligands L1 1-[bis(pyridine-2-ylmethyl)amino]methylpyrene and L2 2-[bis(pyridine-2-ylmethyl)amino]methylquinoxaline were isolated via a one-pot reductive amination in moderate yield. The corresponding rhenium complexes were isolated in good yields and characterised by 1H NMR, MS, IR and UV-Vis studies. X-Ray crystallographic data were obtained for fac-{Re(CO)3( L1)}(BF4), C34H26BF4N4O3Re: monoclinic, P2(1)/c, a = 18.327(2) , = 90.00°, b = 14.1537(14) , = 96.263(6)°, c = 23.511(3) , = 90.00°, 6062.4(11) 3, Z = 8. The luminescence properties of the ligands and complexes were also investigated, with the emission attributed to the appended chromophore in each case.

Pressure powder metallurgy process for consolidating refractory or rhenium alloys using a reduced temperature and elevated pressure. Rhenium metal has high temperature strength and wear resistance but has a very high melting point as a pure metal and thus is difficult to use as a coating for many alloys having lower melting points. The reduced temperature and elevated pressure alloying process of the rhenium allows it to be used as a coating for other metal alloys, such as nickel and steel alloys, providing some high temperature and wear resistance due to the properties of the rhenium material in the coating.
The rates of reaction between flowing chlorine and rhodium, rhenium, and iridium were measured by the rates of mass change of samples of the reacting metal and correlated as functions of temperature and chlorine pressure. Attempts were made to correlate the reaction rates with the vapor pressures and decomposition pressures of the chloride products.

Organorhenium chemistry describes the compounds with Re-C bonds. Because rhenium is a rare element, relatively few applications exist, but the area has been a rich source of concepts and a few useful catalysts. Re exists in ten known oxidation states from −3 to +7 except −2, and all but Re(−3) are represented by organorhenium compounds. Most are prepared from salts of perrhenate and related binary oxides. The halides, e.g., ReCl5 are also useful precursors as are certain oxychlorides. A noteworthy feature of organorhenium chemistry is the coexistence of oxide and organic ligands in the same coordination sphere. Dirhenium decacarbonyl is a common entry point to other rhenium carbonyls. The general patterns are similar to the related manganese carbonyls. It is possible to reduce this dimer with sodium amalgam to Na[Re(CO)5] with rhenium in the formal oxidation state −1. Bromination of dirhenium decacarbonyl gives bromopentacarbonylrhenium(I), then reduced with zinc and acetic acid to ...
The complex Re2(CO)8[-2-C(H)=C(H)Bun](-H), 2.1 reacts with SbPh3 at 68 oC to yield the new σ-phenyl dirhenium complex Re2(CO)8(SbPh3)(Ph)(μ-SbPh2), 2.4 in 72% yield. Compound 2.4 contains two rhenium atoms held together by a bridging SbPh2 ligand. One rhenium atom contains a σ-phenyl group. The other rhenium atom contains a SbPh3 ligand. Compound 2.4 was also obtained in 34% yield from the reaction of Re2(CO)10 with SbPh3 in the presence of UV-vis irradiation together with some monorhenium products: HRe(CO)4SbPh3, 2.5, Re(Ph)(CO)4SbPh3, 2.6 and fac-Re(Ph)(CO)3(SbPh3)2, 2.7 in low yields. Complex 2.4 is split by reaction with an additional quantity of SbPh3 to yield the monorhenium SbPh3 complexes 2.6, 2.7 and mer-Re(Ph)(CO)3(SbPh3)2, 2.8 that contain a σ-phenyl ligand. When 2.4 was treated with hydrogen, the phenyl ligand was eliminated as benzene and the dirhenium complexes Re2(CO)8(μ-SbPh2)(μ-H), 2.10, and Re2(CO)7(SbPh3)(μ-SbPh2)(μ-H), 2.11, were formed that contain a bridging hydrido ligand.
Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic sulfur-free multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a rhenium component, a cobalt component, and a halogen component with a porous carrier material. The platinum group component, rhenium component, cobalt component, and halogen component are present in the multimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum group metal, about 0.01 to about 2 wt. % rhenium, about 0.1 to about 5 wt. % cobalt, and about 0.1 to about 3.5 wt. % halogen. Moreover, these metallic components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group component is present therein in the elemental metallic state, and
Global warming is expected to intensify the effects of coastal anoxia. Knowledge of the causes of geohistorical anoxic episodes may prove critical in developing strategies for the mitigation of or adaptation to the consequences of climate change upon the global aquatic environment. The geochemistry of Re provides the means to acquiring this knowledge. Within oxic waters, Re exists as geochemically-inert ReO4-. Under reducing conditions, Re is removed from the aqueous phase and deposited in sediments. Unfortunately, an incomplete understanding of Re geochemistry hampers exploitation of Re as a paleoredox indicator. Authors purport Re sequestration begins in suboxic environments; others produce evidence supporting removal under sulfidic conditions. Some suggest precipitation as ReS2; others hint at scavenging by pyrite. The proposed research will begin clarifying such issues by positing a plausible pathway to Re fixation. Reductively labile thioperrhenates initiate the pathway: ReVIIO4-(aq) + nH2S(aq) ⇌

Ida and her husband-to-be looked for the then still unknown elements 43 and 75 at the Physikalisch-Technische Reichsanstalt. In 1925, they published a paper (Zwei neue Elemente der Mangangruppe, Chemischer Teil) claiming to have done so, and called the new elements Rhenium (75) and Masurium (43). Only the discovery of rhenium was confirmed. They were unable to isolate element 43 and their results were not reproducible. Their choice of the term masurium was also considered unacceptably nationalistic and may have contributed to a poor reputation among scientists.[citation needed]. Artificially produced element 43 was definitively isolated in 1937 by Emilio Segrè and Carlo Perrier from a discarded piece of molybdenum foil from a cyclotron which had undergone beta decay. It was eventually named technetium due to its artificial source. No isotope of technetium has a half-life longer than 4.2 million years and was presumed to have disappeared on Earth as a naturally occurring element. In 1961 minute ...
The goal of this research is to cyclize octreotide analogues with ⁹⁹[supersript-m]Tc and ¹⁸⁶/¹⁸⁸Re radiometals to be used as diagnostic and therapeutic agents for neuroendocrine tumors, respectively. Several series of octreotide analogues that differ in their sequences, and/or coordination systems (S₂N₂ and S₃N) were developed. Their in vitro receptor binding affinity toward somatostatin receptors was measured via IC₅₀ studies. In vitro stability studies were carried out under physiological conditions on ⁹⁹[superscript-m]Tc-cyclized analogues in phosphate buffered saline, mouse serum, and under high cysteine concentration. The only analogue that expressed high receptor binding affinity was not stable at the tracer level; however, the other analogues were stable at the tracer level but at the expense of their receptor affinity. The effect of metal-cyclization on Tyr³-octreotates receptor binding site was determined via three-dimensional molecular structure ...

0191] The luminescence quantum yields of the Re(PPh3)(CO)3BiPy-BiPh-HMMs obtained in Examples 18 to 19 were measured. Such measurement was carried out using a sample prepared by dispersing 1 mg of each of the Re(PPh3)(CO)3BiPy-BiPh-HMM powders in 4 ml of acetonitrile, by passing an argon gas therethrough for 20 minutes, and then by hermetically sealing the resultant mixture in a container (quartz-made cell). The luminescence quantum yield of each Re (PPh3) (CO)3BiPy-BiPh-HMM was 0.03 when excited with the light having a wavelength of 265 nm. At this time, only the luminescence from the rhenium complex was observed. On the other hand, the luminescence quantum yield of each Re (PPh3) (CO)3BiPy -BiPh-HMM was 0.05 when excited with the light having a wavelength of 350 nm. At this time, only the luminescence from the rhenium complex was observed. It was understood from this result that, when the BiPh in the skeleton of the porous material was excited with the light having a wavelength of 265 nm, ...

This work presents a lab-made automated flow-batch system for headspace single-drop microextraction and on-drop conductometric sensing ammonium. Sample and NaOH answer are concurrently pumped right into a response chamber (RC), the place ammonium is transformed to ammonia by elevating pH. The transformed ammonia then diffuses into the headspace of the RC, and reacts with a 100 mM boric acid drop. The conductivity of the drop is measured by an on-drop conductivity probe, which is made by two stainless-steel contacting electrodes. The end result exhibits that the growing charge of conductivity has a linear relationship to the ammonium focus in pattern (R2 = 0.9945). This methodology has a linear vary as much as 400 μM, a restrict of detection 2.eight μM, a relative normal deviation of 3.0% (200 μM, n = 10) and carryover coefficient 0.028. Measurements of river waters, lake waters and wastewaters have been demonstrated. The recoveries have achieved from 99.Zero to 114%. This methodology avoids ...

The electronic excited states of some platinum(II), rhenium(I) and ruthenium(II) complexes with diimine ligands were studied with spectroscopic and computational tools. This type of complex can form charge-transfer (CT) excited states which are potentially useful for solar energy applications. fac-Re(CO)3(N^N)L] complexes are discussed first. The complexes form luminescent CT states where an excited electron is localized on the N^N ligand. Resonance Raman spectroscopy shows how the origin of this excited electron can change from ligand-based to metal-based depending on donating ligand L. Variations in the N^N ligand in Re(I) complexes are also studied. Time-resolved infrared spectroscopy shows how complexes with 2-pyridyl-1,2,3-triazole (pytri) ligands form excited states with a smaller degree of charge separation than is typically seen. [Ru(pytri)(bpy)2]2+ complexes are shown to form CT states which are comparable to those of [Ru(bpy)3]2+ where an excited electron is localized on a bpy ligand. ...

A bulky, optically active monoanionic scorpionate ligand, tris(4S-isopropyl-5,5-dimethyl-2-oxazolinyl)phenylborate (To P*), is synthesized from the naturally occurring amino acid l-valine as its lithium salt, Li[To P*] (1). That compound is readily converted to the thallium complex Tl[To P*] (2) and to the acid derivative H[To P*] (3). Group 7 tricarbonyl complexes To P*M(CO) 3 (M = Mn (4), Re (5)) are synthesized by the reaction of MBr(CO) 5 and Li[To P*] and are crystallographically characterized. The ν CO bands in their infrared spectra indicate that π back-donation in the rhenium compounds is greater with To P* than with non-methylated tris(4S-isopropyl-2-oxazolinyl)phenylborate (To P). The reaction of H[To P*] and ZnEt 2 gives To P*ZnEt (6), while To P*ZnCl (7) is synthesized from Li[To P*] and ZnCl 2. The reaction of To P*ZnCl and KOtBu followed by addition of PhSiH 3 provides the zinc hydride complex To P*ZnH (8). In this study, compound 8 is the first example of a crystallographically ...

Unlike other fuel cell types, the direct methanol fuel cell does not require a separate hydrogen generation system and therefore has greater commercial potential, particularly for powering portable appliances. However, the limiting factor for the cost-effective performance of such systems is the catalytic activity of the electrodes, in particular the anode. The single most active anode material is platinum, which is usually dispersed on a high surface area carbon support. It has been found that the addition of small amounts of metals such as lead, rhenium, ruthenium and tin to the platinum produces a significant increase in activity. The best of these bimetallic systems is based on a mixture of platinum and ruthenium. However, further worthwhile improvements in anode activity could result from a more fundamental understanding of the methanol decomposition reaction. In recognition of this, the Commission of the European Communities has initiated a research programme which involves collaboration between

Research in fluorescence microscopy presents new challenges, especially with respect to the development of new metal-based fluorophores. In this work, new fac-[Re(CO)3(bpy)L]PF6 (C3) and fac-[Re(CO)3(dmb)L]PF6 (C4) complexes, where L is an ancillary ligand, E-2-((3-amino-pyridin-4-ylimino)-methyl)-4,6-di-tert-butylphenol, both exhibiting an intramolecular hydrogen bond, have been synthesized for use as preliminary probes for fluorescence microscopy. The complexes were characterized using chemical techniques such as UV-vis, 1H-NMR, TOCSY, FT-IR, cyclic voltammetry, mass spectrometry (EI-MS 752.22 M+ for C3 and 780.26 M+ for C4) and DFT calculations including spin orbit effects. The electron withdrawing nature of the ancillary ligand L in C3 and C4 explains their electrochemical behavior, which shows the oxidation of ReI at 1.84 V for C3 and at 1.88 V for C4. The UV-vis absorption and emission properties have been studied at room temperature in acetonitrile solution. The complexes show luminescent ...

When I made my first spice rack with the magnets (version 1.0 and 1.1), I had made little labels for the jars. But I took this to the next level as well... I recently came across Martha Stewarts Avery line of products available at Staples and well fell in love... Heres how I re-labeled my spices. So pretty... You wont be able to see the labels when the jars are on the shelves, but in my organizing ways, I arranged them all alphabetically, so I have a idea based on that plus their colour/texture from the clear jar of what each jar contains. The label just confirms ...
