Solutions containing the components Au+, dppe (dppe is bis(diphenylphosphino)ethane), and Br– in a 1:1:1 ratio can produce three different types of crystals: type A, orange luminescent solvates dimer Au2(dppe)2Br2 (Au2(μ-dppe)2Br2·2(OSMe2), Au2(μ-dppe)2Br2·2(OCMe2), Au2(μ-dppe)2Br2·2(CH2Cl2), Au2(μ-dppe)2Br2·2(HC(O)NMe2)); B, green same (Au2(μ-dppe)2Br2·(NCMe) Au2(μ-dppe)2Br2·0.5(C4H10O)); C, polymer ({Au(μ-dppe)Br}n·0.5(C4H10O) {Au(μ-dppe)Br}n·(CH2Cl2)).

The solid state interconversions of four different crystalline compounds containing the Au2(dppe)2I2 unit (dppe is bis-(diphenylphosphino)ethane) have been observed and characterized through X-ray diffraction emission spectroscopy. Treatment AuI in acetone with dppe yields polymorphs: α-Au2(μ-dppe)2I2·2OCMe2 (1) orange β-Au2(μ-dppe)2I2·2OCMe2 (2) green emission. Both polymorphs contain dimeric molecules three-coordinate gold(I) centers that are further apart emitting (Au⋯Au distance,...
Environmental damage from serious nuclear accidents should be urgently restored, which needs the removal of radioactive species. Radioactive iodine isotopes are particularly problematic for human health because they released in large amounts and retain radioactivity a substantial time. Herein, we prepare platinum-coated iron nanoparticles (Fe@Pt) as highly selective reusable adsorbent species, i.e., iodide (I-), (I2), methyl (CH3I). Fe@Pt selectively separates species seawater groundwater...
To efficiently degrade organic pollutants, photocatalysts must be effective under both ultraviolet (UV) radiation and sunlight. We synthesized a series of new metal–organic frameworks by using mild hydrothermal conditions. These incorporate three distinct bipyridyl ligands: pyrazine (pyr), 4,4′-bipyridine (bpy), 1,2-bis(4-pyridyl)ethane (bpe). The resulting compounds are denoted as [Cu(pyz)(H2O)2MF6], [Cu(bpy)2(H2O)2]·MF6, [Cu(bpe)2(H2O)2]·MF6·H2O [M = Zr (1, 3, 5) Hf (2, 4, 6)]. All six...
91 Background: When COVID-19 pandemic started in 2020 the US, Centers for Medicare and Medicaid Services (CMS) recommended that all non-urgent procedures, including screening colonoscopies, be delayed until stabilization. This was done to prevent spread of virus via colonoscopy since presence fecal samples has been reported infected patients. Little is known impact on number colorectal cancer (CRC) performed US. Methods: We utilized & Database which provides claims data 2013-2022....
Treasure chests: The Group 11 metals CuI, AgI, and AuI form tetrahedral supramolecular clusters with a rigid threefold-symmetric phosphine ligand. These clusters, which assemble by metal–phosphine interactions, are the first to across an entire group of periodic table. Cu+ green, Ag+ pale blue, Au+ I− red, P purple. Detailed facts importance specialist readers published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted...
Tracheal bronchus (TB) is an aberrant, accessary or ectopic arising almost exclusively from the right side of tracheal wall above carina. In our center, 673 bronchoscopic examinations were performed 2009 to 2011 in patients undergoing one lung ventilation (OLV) and 3 TB found. The incidence a at bronchoscopy was 0.45% research, which consistent with reported range 0.1-5%. clinician should consider possibility anomalous upper lobe perform prior bronchial blocker insertion, when left-sided OLV...
An array of coordination-driven supramolecular metal–ligand clusters has been synthesized using polytopic phosphine ligands and coinage metals (Cu+, Ag+, Au+).

Four crystalline dimers of the type, Au(I)(2)(μ-PnP)(2)I(2), where PnP is PPh(2)(CH(2))(n)PPh(2) with n = 3, 4, 5, and 6 have been prepared characterized by single-crystal X-ray diffraction (31)P NMR infrared spectroscopy. Au(I)(2)(μ-P3P)(2)I(2) Au(I)(2)(μ-P6P)(2)I(2) are centrosymmetric planar Au(I)P(2)I units oriented in antiparallel fashion. Remarkably, noncentrosymmetric Au(I)(2)(μ-P5P)(2)I(2) has its parallel manner. Au(I)(2)(μ-P4P)(2)(μ-I)(2) unique, since it contains four-coordinate...
The mono- and di-chloroform solvates of [Au2 (μ-1,2-bis(diphenylarsino)ethane)2 ](AsF6 )2 undergo single-crystal-to-single-crystal transformations that result in gain (over 12 hours) or slow loss five years) only one chloroform molecule. change solvation results changes the structure luminescence digold cation. cation consists a pair slightly bent As-Au-As units are connected through two bridging dpae ligands by aurophilic interactions with Au⋅⋅⋅Au contacts 3.05152(15) Å disolvate 2.9570(5)...
Isotopic analyses of plutonium and low-enriched uranium mixtures with particle sizes 0.6–3.3 μm were performed using thermal ionization mass spectrometry a continuous heating method to verify its effectiveness for the accurate analysis minor isotopes without sample pretreatment. The mixed particles used in this study prepared from solution (SRM 947) (U010, 235U 1% enriched) reference materials. isotope ratios individual particles, including 238Pu/239Pu, 241Pu/239Pu as well 240Pu/239Pu,...
To avoid deep hypothermia-related side effects, moderate hypothermic circulatory arrest (HCA) is commonly employed during aortic arch repair, thereby jeopardizing end-organ protection. We sought to analyse the effect of intermittent lower body perfusion (ILBP) on function repair acute DeBakey type I dissection (AIAD). Between May 2008 and 2011, 107 patients underwent surgical for AIAD. All operations were performed with selective cerebral (SCP) under either HCA only (n = 57) or ILBP 50)....

Methods There were 114 patients enrolled into who underwent general anesthesia randomly allocated one 2 groups; LMA group (n = 57) or SLIPA 57). After insertion, insertion success rate, time, and hemodynamic responses accessed. surgery, postoperative morbidity (sore throat, dysphonia, dysphagia) evaluated.

Solutions containing the components Au(+), dpae (dpae is 1,2 bis-(diphenylarsino)ethane), and X(-) (X Cl, Br, or I) can produce two different types of crystals with composition Au(2)(μ-dpae)X(2): colorless blocks needles. Crystallographic studies these show that they are polymorphs structural motifs. In α-polymorphs, which isostructural, individual molecules Au(2)(μ-dpae)X(2) form discrete dimers through identical Au···Au contacts. β-polymorphs, each have unique crystallographic parameters,...
