This paper describes the synthesis, crystal structure, and photophysical properties of a new compound Rb2CdBr2I2. It crystallizes in noncentrosymmetric space group Ama2. In crystal, all distorted tetrahedron [CdBr2I2]2– groups are arranged way such that Cd–I bonds located same side Cd atoms resulting net polarization. Rb2CdBr2I2 showed powder second harmonic generation (SHG) response 4 times KH2PO4 (KDP). The preliminary measurement indicated it exhibits large laser-induced damage threshold...
Abstract A family of nonlinear optical materials that contain the halide, oxide, and oxyhalide polar units simultaneously in a single structure, namely ABi 2 (IO 3 ) F 5 (A=K ( 1 ), Rb Cs )), have been designed synthesized. They crystallize same space group P with two‐dimensional double‐layered framework constructed by [BiF ] 2− [BiO 4 5− connected to each other four atoms, which two [IO − groups are linked unit on side. hanging Bi−F bond is located side via ionic interaction layer‐inserted...
Abstract Tacrolimus has a narrow therapeutic window and considerable variability in clinical use. Our goal was to compare the performance of multiple linear regression (MLR) eight machine learning techniques pharmacogenetic algorithm-based prediction tacrolimus stable dose (TSD) large Chinese cohort. A total 1,045 renal transplant patients were recruited, 80% which randomly selected as “derivation cohort” develop dose-prediction algorithm, while remaining 20% constituted “validation test...
Laser damage threshold (LDT) has been considered as a key index, apart from the nonlinear optical (NLO) effect, to characterize performance of mid-infrared NLO material. This paper reports and compares properties RbIO3 RbIO2F2 potential materials be used in mid-IR region. is known compound, its powder SHG (second harmonic generation) effect carefully measured this work for first time strong 20 times that KDP, powders show high 125 MW/cm2. In order investigate influence on by partially...
A general approach to the design and synthesis of a new series geminal-substituted tetraarylethene (g-TAE) chromophores with aggregation-induced emission (AIE) properties has been developed via Corey–Fuchs reaction subsequent Suzuki/Stille coupling reactions. To demonstrate synthetic simplicity versatility this approach, fluorophores diverse electronic characteristics have synthesized. The validation geminal structure bulky steric effect on bond lengths dihedral angles is further confirmed...
Self-inhibition has been observed widely in hierarchical biochemical processes but yet to be demonstrated pure molecular physical rather than chemical or biological processes. Herein, we report an unprecedented example of self-inhibition during the supramolecular chirality induction, memory, erasure, and inversion pillar[5]arene (P[5]) derivatives. The addition chiral alanine ethyl ester bulky substituent-modified P[5]s led time-dependent induction due shift equilibrium SP RP conformers...

Clear cell renal carcinoma (ccRCC) is the most common malignancy in adults, incidence of which continues to increase. The lipid droplet protein perilipin 2 (PLIN2), was originally considered an RNA transcript, markedly expressed during adipocyte differentiation. In addition, it has been observed be elevated numerous types cancer, including ccRCC; however, its essential function remains unclear ccRCC. present study examined expression PLIN2 ccRCC, and aimed determine association between...
The GNSS Occultation Sounder instrument onboard the Chinese meteorological satellite Fengyun-3C (FY-3C) tracks both GPS and BDS signals for orbit determination. One month’s worth of dual-frequency data during March 2015 from FY-3C is analyzed in this study. measurement quality evaluated terms quantity as well code multipath error.
