Personoriented Method inside Analyzing ChineseHungarian Character and Effective Dysfunction Information

Flexible metal-organic framework (MOF) materials have the ability to perform stimulated sudden volume contractions, and thus attract increasing attention for use in potential applications such as actuators or sensors. Here, the structural transition of MIL-53(Cr) loaded with a high concentration of CH3OH (CH3OH) guest molecules, which cause internal pressure due to guest-guest interactions, was investigated. The pressure triggering the structural transition can be enhanced by high guest molecule loadings (1 CH3OH per unit cell (UC) 5 MPa, empty 53 MPa, 7 CH3OH per UC 90 MPa, and 8 CH3OH per UC 280 MPa). The asymmetrical and small distortion of the organic-inorganic connections are the main microscopic characteristic of the structural transition of MIL-53(Cr) with a high CH3OH loading. The external pressure and the internal pressure, instead of the adsorption of the guest molecules, became dominant in the structural transition of MIL-53(Cr). Current studies showed that the high-pressure response of the flexible MOF structure may broaden the acceptable pressure range in future actuator or sensor applications.Owing to its important biological functions in many physiological and pathological processes, it is necessary to develop efficient and appropriate detection methods for monitoring the levels of Cys in biological systems. Based on this, a novel rhodol-isophorone derivative (RHI) was designed and synthesized as a reaction-based fluorescence probe for specific detection of Cys with high sensitivity and large Stokes shift (155 nm). This probe was composed of an acrylate moiety (recognition group) and a rhodol-isophorone derivative (fluorophore). Probe RHI could react with Cys rapidly (15 min) with a 100-fold fluorescence enhancement. read more The limit of detection value was calculated to be 0.168 μM. When Cys was added, the color of the probe RHI solution turned from yellow to blue, indicating that Cys could be monitored by the naked eye. In addition, probe RHI was successfully utilized for detecting Cys in environmental water and milk samples. More importantly, the probe could be applied to imaging Cys in living cells with low cytotoxicity and good biocompatibility.Temperature-dependent electrical and magneto-transport measurements have been performed on devices composed of few layer (4L) graphene grown directly on SiO2/Si substrates using the CVD method. An intrinsic energy band-gap of 4.6 meV in 4L graphene is observed, which primarily dictates the current transport at T 200 K. The coexistence of phonon mediated carrier mobility and defect induced weak localization effects in measuring devices suggests low disorder and impurity scattering.Although luminescent indium(III) based halide perovskites have been widely investigated, the study of emissive indium(III) halide hybrids is limited. Three indium(III) chloride hybrids based on a bpym ligand were synthesized, namely [EPy]2[InCl4(bpym)InCl4]·DMF (1), [EPy]2[InCl4(bpym)InCl4] (2), and [BPy]2[InCl4(bpym)InCl4] (3) (EPy = N-ethylpyridinium; BPy = N-butylpyridinium; bpym = 2,2'-bipyrimidine). They all exhibit a zero-dimensional structure, in which the ligand bpym interconnects two [InCl4]- to form a [InCl4(bpym)InCl4]2- anion that is further charge-compensated by the corresponding pyridinium cations. This is the first time using bpym to coordinate with an In atom. At 298 K, 1 exhibits a weak emission at 600 nm while 2 and 3 exhibit emissions peaking at 500 nm and 540 nm, respectively. Interestingly, the DMF solvent molecule in 1 can be removed by heating, thus resulting in the structural transformation of 1 into 2 together with a photoluminescence (PL) change. Density functional theory (DFT) calculations confirm that halogen-to-ligand charge-transfer (HLCT) occurs in the emission process. To the best of our knowledge, this is the first report on PL of ionic indium(III) halide hybrids incorporating organic ligands.The first phosphinoboronic ester bearing a fused bicyclic framework was synthesised by either deprotonation and hydride abstraction or Rh-catalysed dehydrogenation of a hydrophosphineboronic ester. The phosphinoboronic ester reacted as a Lewis acid with KF/18-crown-6, pyridine and DMAP to give the corresponding adducts. Furthermore, its crystal structure shows a remarkably short P-B bond in comparison with other P-B bonded derivatives in spite of the trigonal pyramidal geometry of the phosphorus. Consistent with the phosphorus pyramidality, the π-type donor-acceptor interaction of the P-B bond is small as revealed by the DFT calculations. The P-B bond shared within the fused six-membered rings has to shorten because of the geometrical requirement and high s-character of the boron.Exploring the simple yet well-controlled synthesis of atomically dispersed Pt catalysts is a crucial endeavour for harvesting clean hydrogen via the kinetics-favoured acidic electrochemical water splitting technique. Here we employed the use of defective carbon sheets by KOH etching as a substrate for the in situ surface reduction of Pt(IV) ions to prepare atomically dispersed Pt. Physical and electrochemical characterizations reveal a strong interaction between the carbon substrate and Pt species, providing the basis for the in situ surface reduction. The atomically dispersed Pt electrocatalyst exhibited high HER performance in a sulfuric acid electrolyte, with an overpotential as low as 55 mV at a current density of 100 mA cm-a, and better catalytic durability compared to the commercial Pt/C. The mechanism study revealed that the full utilization of atomically dispersed Pt and the optimized catalyst surface may enhance the recombination of adsorbed *H via the Volmer-Tafel mechanism to produce H2 at a high efficiency. In the light of high activity, durability, and low cost, the atomically dispersed Pt material is promising for acidic HER application.In line with the advances in high-throughput technologies, multiple omic datasets have accumulated to study biological systems and diseases coherently. No single omics data type is capable of fully representing cellular activity. The complexity of the biological processes arises from the interactions between omic entities such as genes, proteins, and metabolites. Therefore, multi-omic data integration is crucial but challenging. The impact of the molecular alterations in multi-omic data is not local in the neighborhood of the altered gene or protein; rather, the impact diffuses in the network and changes the functionality of multiple signaling pathways and regulation of the gene expression. Additionally, multi-omic data is high-dimensional and has background noise. Several integrative approaches have been developed to accurately interpret the multi-omic datasets, including machine learning, network-based methods, and their combination. In this review, we overview the most recent integrative approaches and tools with a focus on network-based methods. We then discuss these approaches according to their specific applications, from disease-network and biomarker identification to patient stratification, drug discovery, and repurposing.Herein, a new IR window material CdPbOCl2 is rationally designed and fabricated by a heavy-metal oxide and halide combined strategy. The millimeter-scale CdPbOCl2 single crystal exhibits a wide IR transparent region (1.4-18.0 μm) and excellent comprehensive properties. The results provide an insight into the exploration of broad-band IR window materials.It is proved that L-guanosine (L-G) as an enantiomer of D-guanosine (D-G) forms more stable gels than D-G, suggesting that alteration of chirality may be a new strategy for improving the lifetime stability of supramolecular hydrogels. Experiments for three-dimensional cell culture reveal that the L-G gel is a candidate for the extracellular matrix.Here, an Au-Cu dual-electrode tip was designed to monitor the effect of Cu2+ on the membrane permeability of a single living cell in situ using scanning electrochemical microscopy. The probe approach curves (PACs) were obtained using potassium ferricyanide as a redox mediator. Meanwhile, according to the simulation, theoretical PACs could be acquired. Thus, the cell membrane permeability coefficient (Pm) values were obtained by overlapping the experimental PACs with the theoretical values. Cu2+ was directly generated by electrolyzing the Cu electrode of the dual-electrode tip to investigate its effect on the cell membrane permeability in situ. This work has potential value to improve the understanding of the mechanism of acute heavy metal damage on the cell membrane and will also help clarify the role of heavy metal ions in physiological or pathological processes.The quality evaluation of hawthorn leaves in different geographical regions derived from the dried leaves of Crataegus pinnatifida Bge. Var. Major N.E.Br. or Crataegus pinnatifida Bge., a common blood-activating and stasis-eliminating traditional Chinese medicine, has hardly been reported. In this study, the chemical comparison of 40 batches of hawthorn leaf samples collected from Hebei, Liaoning, Shandong and Shanxi Provinces was performed using an ultra-high performance liquid chromatography with electrospray ionization-tandem mass spectrometry-based metabolic profile and pattern recognition analysis approach. A total of 233 compounds were determined. Among them, 40 compounds were selected as potential metabolites responsible for the differential clustering, and the differential metabolite-based evaluation model was applied to well distinguish the origin of seven batches of hawthorn leaves sold on the market. Further analysis of the KEGG pathway showed that five core metabolites containing flavonoids and lignins were mainly involved in flavonoid biosynthesis, flavone and flavonol biosynthesis, and stilbenoid, diarylheptanoid and gingerol biosynthesis. Taking the content of flavonoids, core markers, as the evaluation basis, it was found that the quality of hawthorn leaves in Hebei and Liaoning was better. The study provides a reference for the rational utilization of hawthorn leaves, and highlights that the metabolomics-driven analysis method is more suitable for the quality evaluation of traditional Chinese medicine.Studies of methylene blue-backboned polymers (MBPs) are hindered by the limited availability of polymerization methods. Herein, we developed an oxidative polymerization method to produce MBPs. The polymerization is performed in aqueous medium, and is organic solvent-free, heavy metal-free, time-efficient (on a timescale of minutes), and does not need pre-formed methylene blue chromophores. The effects of the alkyl chains of the MBPs on the photophysical properties and self-assembly behavior (e.g., vesicles and nanorings) are significant, which highlights the possibility of controlling the MBP properties via rationally tailoring the functionality of the MBP monomers prior to polymerization. Importantly, the self-assembly structures can be predicted using the dissipative particle dynamics (DPD) simulation method.This study reports the simultaneous colorimetric detection of urea, H2O2, and pH in milk samples using microfluidic paper-based analytical devices (μPADs) fabricated through a craft cutter printer. Paper-based devices were designed to contain three detection zones interconnected to a sampling zone by microfluidic channels. Colorimetric analysis was performed using images digitalized through an office scanner. The volumes of chromogenic and sample solutions were optimized, and the best colorimetric performance was achieved by adding 0.5 and 10 μL into detection and sampling zones, respectively. Simultaneous assays were then carried out, and the recorded responses revealed a linear behavior in the concentration ranges from 0-30.0 mmol L-1, 0-10.0 mmol L-1 and 6.0-9.0 for urea, H2O2 and pH, respectively. The limit of detection values obtained for urea and H2O2 were 2.4 mmol L-1 and 0.1 mmol L-1, respectively. For pH measurements, colorimetric assay allowed the monitoring of solution pH with a resolution of 0.25 units.
