Sr2IrO4 was predicted to be a high temperature superconductor upon electron doping since it highly resembles the cuprates in crystal structure, electronic structure and magnetic coupling constants. Here we report scanning tunneling microscopy/spectroscopy (STM/STS) study of with surface by depositing potassium (K) atoms. At 0.5-0.7 monolayer (ML) K coverage, observed sharp, V-shaped gap about 95% loss density state (DOS) at EFand visible coherence peaks. The magnitude is 25-30 meV for...
The superconductivity discovered in iron pnictides is intimately related to a nematic ground state, where the ${C}_{4}$ rotational symmetry broken via structural and magnetic transitions. We here study nematicity NaFeAs with polarization-dependent angle-resolved photoemission spectroscopy. A uniaxial pressure was applied on sample overcome twinning effect low temperature ${C}_{2}$-symmetric state obtain much simpler electronic structure than that of twinned sample. found undergoes an...
Single-layer FeSe films with extremely expanded in-plane lattice constant of 3.99A are fabricated by epitaxially growing FeSe/Nb:SrTiO3/KTaO3 heterostructures, and studied in situ angle-resolved photoemission spectroscopy. Two elliptical electron pockets at the Brillion zone corner resolved negligible hybridization between them, indicating symmetry low energy electronic structure remains intact as a free-standing single-layer FeSe, although it is on substrate. The superconducting gap closes...
The diversities in crystal structures and ways of doping result extremely diversified phase diagrams for iron-based superconductors. With angle-resolved photoemission spectroscopy, we have systematically studied the effects chemical substitution on electronic structure various series Beyond Fermi-surface alteration that has been reported most often past, found two more extraordinary doping: (1) site band dependencies quasiparticle scattering and, importantly, (2) ubiquitous significant...
Diiron dithiolate complexes have received special attention because of their structural similarity to the active site [FeFe]-hydrogenases, which are most efficient and fastest catalysts for generation dihydrogen in nature. Recently, we established a novel way prepare phosphine-substituted diiron aza- oxadithiolate complexes. Reaction Fe2(μ-SCH2OH)2(CO)6 several phosphine ligands L (L = PPh3, PPh2(2-C5H4N), P(C6H4-4-CH3)3) affords intermediate Fe2(μ-SCH2OH)2(CO)5L, while situ reacts with...
Three new d<sup>10</sup> based MOFs using 5-[bis(3-carboxybenzyl)-amino]isophthalic acid were synthesized and their sensing behavior towards nitroaromatics was evaluated.
A high-performance variant of PLA depolymerase, RPA1511, designated R5, was engineered using combinatorial computational design tools to facilitate closed-loop recycling waste.
Increasing evidence indicates that the decreased expression of microRNA-133a (miR-133a) may be correlated with poor survival for cancer patients. Thus, we performed this meta-analysis to evaluate prognostic value miR-133a in solid cancers.Eligible studies were gathered by searching on PubMed, Web Science, and Embase. Using STATA 12.0 software, pooled hazard ratios (HRs) their corresponding 95% confidence intervals (CIs) total subgroup analyses calculated investigate possible correlation...
AIM:To investigate the microRNA (miRNA) expression profile in gastrointestinal stromal tumor (GIST) tissues that could serve as a novel diagnostic biomarker for GIST detection. METHODS:We performed quantitative real-time reverse transcriptase polymerase chain reaction assay to analyze of 1888 miRNAs sample set included 54 tissue samples. RESULTS:We found dysregulation several may be related malignant potential GISTs.Six these miRNAs, hsa-let-7c, miR-218, miR-488#, miR-4683, miR-34c-5p and...

A practical chemoenzymatic method for the asymmetric total synthesis of d-biotin (1) starting from commercially available cis-1,3-dibenzyl-2-imidazolidone-4,5-dicarboxylic acid (2) has been developed. The key step is highly enantioselective hydrolysis meso-dicarboxylic esters by a polymer-supported pig liver esterase and introduction formyl group at C-4 position in 4 via Grignard reaction. PLE can be recovered quantitatively reaction mixture simple filtration reused without significant loss activity.
We report an angle-resolved photoemission spectroscopy study of a ${\mathrm{ThCr}}_{2}{\mathrm{Si}}_{2}$-type superconductor ${\mathrm{YFe}}_{2}{\mathrm{Ge}}_{2}$ (${T}_{c}\ensuremath{\approx}1.8$ K) in the normal state. The resolved low-energy band structure mainly consists several flat Fe bands, while renormalization factors different bands range from 1.7 to 2.8. Around Fermi level, these contribute high density states, which may account for unusually Sommerfeld coefficient...
