Abstract With the development of modern industry, water pollution is getting severer which causes huge environmental problems. In this work, novel photocatalytic polyelectrolyte composite hydrogels based on crosslinked poly(2-acrylamido-2-methylpropane sulfonic acid) equipped with graphite carbon nitride (g-C 3 N 4 ) were exploited via a facile preparation route, exhibited extremely high removal ratio 95 % and 94.5 to Rhodamine B tetracycline, respectively, through synergistic effect...
Abstract The controlled release and enhanced penetration of drugs to deep‐seated tumors is highly desirable but faces many challenges. Herein, supramolecular biomimetic nanoaggregates (HFCu NAs) are constructed with fluorinated histidine copper ions via multivalent interactions (metal coordination aromatic packing), affording tumor microenvironment responsive “turn‐on” 19 F magnetic resonance imaging （ MRI） guided drug delivery specific therapy. By virtue ligand engineering pH‐triggered...
Abstract The technology of through-silicon via (TSV) is extensively employed for achieving dense 3D integration. TSV facilitates the electrical interconnection various layers integrated circuits in a vertical orientation, thereby allowing creation sophisticated and space-efficient systems that incorporate diverse functionalities. This work reports fabrication with dual annealing-CMP processes to explore influence annealing CMP on evolution TSV-Cu microstructures protrusions. results show...
Abstract Two‐armed chiral calix[4]arenes ( 3a – c ) functionalized at the lower ring with L ‐tryptophan units have been prepared and structures of these receptors characterized by IR, MS, 1 H, 13 C NMR spectroscopy elemental analysis. The enantioselective recognition has studied fluorescence titration H spectroscopy. exhibited different abilities towards some enantiomers materials formed 1:1 complexes between host guest. Receptor exhibits excellent fluorescent ability N ‐Boc‐protected...
Abstract Calix[4]arene‐based two‐armed chiral anion receptors 3a and 3b have been synthesized examined for their anion‐binding abilities by UV/Vis absorption 1 H NMR spectroscopy. The results of nonlinear curve fitting indicate that form 1:1 stoichiometric complexes with the L ‐ or D ‐α‐phenylglycine multiple hydrogen‐bonding interactions exhibit good enantioselective recognition enantiomers α‐phenylglycine anions ( : K ass(L) / ass(D) = 4.76; 2.84). marked colour changes observed...
The success of online retail platforms with hybrid reselling and agency selling has been well documented. Recently, manufacturers are expanding channels in competitive (such as JingDong Tmall) on the basis reselling. Considering two asymmetric platforms, we investigate incentive for channel expansion under various strategies: incumbent platform, selling, or competing platform. Our analysis shows that manufacturer's strategies depend market potential ratio, competition intensity, costs....
Abstract Two multi‐armed neutral fluorescent anion receptors ( 1 , 2 ) bearing multiple amide and thiourea binding sites were synthesized. Study of their UV/Vis fluorescence spectra indicates that both form 1:1 complexes with dicarboxylate anions, the sensitivity for recognition is related to chain lengths these anions. Upon addition intensities host solutions changed significantly. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
Abstract Four linear thiourea anion receptors ( 1 – 3 ) derived from simple amino acid have been synthesized and their bonding properties with various chiral N‐protected anions were examined by using UV–vis fluorescence titration experiments. Receptors 1a , 2, exhibit excellent enantioselective recognition abilities towards N ‐Boc‐protected alanine in the spectra, obvious difference color of solution indicate that enantiomers ‐Boc‐alanine could be distinguished naked eye directly. Receptor...

Their binding abilities halide anions, AcO−, [Formula: See Text] studied by UV-Vis spectroscopy in DMSO. The sensors showed a notable selective color response to F− anion from colorless green-yellow recognition. structures of the their behaviors are discussed. association constants calculated nonlinear fittings 1:1, 1:2 or 1:1 1:2.
Abstract A series of chiral ferrocene‐containing thiourea derivatives have been synthesized, and their enantioselective recognition properties were investigated by UV/Vis titration. Receptors 5a 6a exhibit excellent abilities towards N ‐acetylaspartate. The differences in solution colour can be observed directly the naked eye. minimum energy structures also obtained theoretical DFT calculations. (© Wiley‐VCH Verlag GmbH & Co.
