Abstract ：
Calcite is a promising material choice for adsorbing phosphates because of its abundance and environmentally benign nature. However, the slow adsorption kinetics and hence low adsorption capacity within a short time frame hinders its practical application. In this work, we solve these problems by presenting a low Mg2+-doped calcite adsorbent, Mg-10. With a 3.75 wt% of Mg2+ doping, Mg-10 exhibits a remarkable adsorption capacity of 157.7 mg P/g. It also demonstrates a substantial boost in the adsorption kinetics, achieving a sixfold increase in adsorption capacity within 24 h compared to the undoped calcite. Meanwhile, Mg-10 not only offers improved adsorption selectivity but also maintains a stable effluent pH, underscoring its environmental compatibility. By conducting soil column experiments, we find that Mg-10 quickly captures the excess phosphates during the mimicking fertilization process, and slowly releases the nutrient afterwards, which can increase the feralization efficiency. These results provide alternative strategies for managing phosphate pollution originated from fertilization, and underscores the potential of Mg-10 in sustainable agriculture and environmental remediation.

Abstract ：
An eight-sided prism sample, obtained from a hot-rolled AZ31 magnesium alloy sheet, was compressed at room temperature along the transverse direction to investigate the influence of local strain on twinning behavior using electron backscatter diffraction (EBSD) measurements, hardness distribution, and metallographic observations. The octagonal surface of the sample was divided into distinct regions based on hardness distribution and metallographic observations. Combined analysis of the Schmid factor (SF) and the strain compatibility factor (m') was employed to study twin variant selection. Basal on SF ratio distribution, the Schmid factor criterion, can predict over 75% of observed twin variants in regions A and D (normal stress samples). In contrast, 64% of twin variant selection behavior in region C (shear stress sample) can be effectively explained using a pure shear model. Twin variants with high strain compatibility factors may prefer activation to reduce stress concentration. The strain compatibility factor is more appropriate than the Schmid factor for analyzing the effect of local strain on the selection behavior of twin variants.

Abstract ：
Self-assembly is an important strategy to construct supramolecular frameworks. Small change in the assembling units often leads to significant variations in the self-assembly structures. In the work, we obtain two supramolecular frameworks assembled by different [EuL2]3+ units (L = tris((5,6-dimethyl-1H-benzo[d]imidazol-2-yl) methyl) amine). One meso compound {[EuIIIL2]& sdot;(H2O)6 & sdot;Cl3} (Meso-EuL2) is assembled by an achiral meso[EuL2]3+ unit, forming a supramolecular three-dimensional framework through six-fold intermolecular pi-pi interactions. The other is a racemic compound {[EuIIIL2]& sdot;(CH3OH)5 & sdot;Cl3} (Rac-EuL2), assembled by two chiral rac[EuL2]3+ units predominantly via hydrogen bonding, leading to a layered supramolecular framework. The luminescent properties are different between Meso-EuL2 and Rac-EuL2, with Meso-EuL2 exhibiting more excimerlike emissions, which is likely caused by its stronger pi-pi interactions in the structure.

Abstract ：
To determine multiple microRNAs (miRNAs) from cells simultaneously is essential for understanding biological functions. Capillary electrophoresis (CE) can simultaneously determine multiple miRNAs by separation. Nevertheless, similar lengths and low concentrations in cells make miRNAs hard to separate and detect. In this study, CE with laser-induced fluorescence detection was combined with catalytic hairpin assembly (CHA) to determine three miRNAs, miR-21, miR-31, and miR-122. The amplification products of CHA, which were DNA duplexes, were designed to have different lengths for different miRNAs. This allowed for easy separation of the duplexes of different miRNAs by CE. The indirect determination of miRNAs was then achieved by separating and detecting these duplexes. A magnetic field was first applied on the capillary sieving electrophoresis to assist in the separation of the duplexes. Under the optimal conditions, the three duplexes could be completely separated within 2.5 min with the detection limits of miRNAs in the range 1.12-4.05 x 10-15 M. MiR-21 and miR-31 were successfully determined from Hela cells, while miR-122 was determined from chicken livers by this method. The recoveries ranged from 97.5% to 118%. The developed method was sensitive and reliable for miRNA determination.

Abstract ：
Developing light-harvesting materials with broad spectral response is of fundamental importance in full-spectrum solar energy conversion. We found that, when a series of earth-abundant metal (Cu, Co, Ni and Fe) salts are dissolved in coordinating solvents uniformly dispersed nanodots (NDs) are formed rather than fully dissolving as molecular species. The previously unrecognized formation of this condensed state is ascribed to spontaneous aggregation of molecular transition-metal-complexes (TMCs) via weak intermolecular interactions, which results in redshifted and broadened absorption into the NIR region (200-1100 nm). Typical photoredox reactions, such as carbonylation and oxidative dehydrogenation, well demonstrate the feasibility of efficient utilization of NIR light (lambda>780 nm) by TMCs NDs. Our finding provides a conceptually new strategy for extending the absorption towards low energy photons in solar energy harvesting and conversion via photoredox transformations.

Abstract ：
MicroRNAs (miRNAs) play important roles in physiological and pathological processes of cells. To develop a fast, simple and sensitive method to determine miRNAs is significant for miRNA studies. In this work, determination of microRNA-122 (miR-122) was achieved by laser-induced fluorescence (LIF) detection. A vial-LIF interface was first applied for sample analysis. A two-step amplification of the fluorescence signal for miR-122 was designed and realized by applying duplex-specific nuclease in the cleaving of two sensing probes. Under optimized conditions, the analysis of a miR-122 sample could be completed in less than 50 min. Only 10 mu L sample was required for each test and the detection limit for the method was 0.60 pM equal to 1.2 amol of miR-122 in 10 mu L solution. Lastly, the developed method was successfully applied to determine miR-122 in chicken and duck liver. The developed method was fast, selective, sensitive and sample-saving for the determination of miRNAs.

Abstract ：
For laser-induced fluorescence (LIF), the SNR and related concentration detectability was severely limited by background signal (noise). Herein, an axial-excitation LIF based on pinhole metal-capillary (PMC) and direct laser-diode excitation was proposed. An overall similar to 480 fold improvement on SNR was realized, because the lasersidewall interaction (LSI) and related background signal (noise) can be effectively suppressed in PMC by avoidance of laser leakage and laser contact with capillary sidewall. For rhodamine B detection without sample enrichment, a detection limit of concentration (DLC) of 0.4 pM was obtained, which is 2.5 fold lower than the DLC (1 pM) of commercial LIFs equipped with bulky and expensive Ar+ laser. For selective detection of Cu2+, a DLC of 5 pM was realized, which is more than 40 fold lower than that of previous fluorimetry detection with similar quantum-dot probe. The PMC-LIF features compact (16 x 4 x 4 cm(3)), low-cost and high concentration detectability.

Abstract ：
In this work, high-speed micellar electrokinetic chromatography with LIF detection was applied to study the antagonism between three intestinal bacteria, Escherichia coli (E. coli), Bacillus licheniformis (B. licheniformis) and Bacillus subtilis (B. subtilis). The fluorescent derivatization for the bacteria was performed by labeling the bacteria with FITC. In a high-speed capillary electrophoresis (HSCE) device, the three bacteria could be completely separated within 4 min under the separation mode MEKC. The BGE was 1 x TBE containing 30 mM SDS and 1.5 x 10(-5) g/mL polyethylene oxide. The limits of detection for E. coli, B. licheniformis and B. subtilis were 2.80 x 10(6) CFU/mL, 1.60 x 10(6) CFU/mL and 1.90 x 10(6) CFU/mL respectively. Lastly, the method was applied to investigate the antagonism between the three bacteria. The bacteria were mixed and cultured for 7 days. The samples were separated and determined every day to study the interaction between bacteria. The results showed that B. licheniformis and B. subtilis could not inhibit each other, but they could effectively inhibit the reproduction of E. coli. The method developed in this work was quick, sensitive and convenient, and it had great potential in the application of antagonism study for bacteria.

Abstract ：
As a common plasma protein, alpha-fetoprotein (AFP) is widely applied as the tumor biomarker for the diagnosis of many cancers. To develop a low cost, high sensitive and high-throughput method for the determination of AFP is significant for the disease diagnosis. In this work, an immunoassay with sandwich-type structures was performed on a paper-based chip for the analysis of AFP. AFP could be captured by the primary antibodies which were immobilized on the paper by chitosan. On the secondary antibodies, the modified initiator DNAs could trigger the hybridization chain reaction to amplify the fluorescence signals for AFP. A laser-induced fluorescence detector coupled with an interface was applied to detect the targets on the paper-based chip. Under the optimized conditions, the detection limit for AFP was 1.0 pg/mL. For every test, the sample solution consumption only was 10 mu L. Finally, the method was applied to determine the AFP in serum of normal person and hepatopaths with hepatic malignant tumor, chronic hepatitis B and other suspected liver diseases. The AFP could be found from all of the samples and the results were similar to that obtained by chemiluminescence immunoassay. The recoveries for AFP ranged from 93.8% to 106%, which indicated the method was reliable. The method based on paper chip had great potential in the application of AFP determination.

Abstract ：
MicroRNAs (miRNAs) are considered as the potential biomarkers for many cancers. To determine miRNAs in cancer cells is significant for realizing these diseases. In this work, a microfluidic paper-based laser-induced fluorescence sensor based on duplex-specific nuclease (DSN) amplification was developed and applied to selectively and sensitively determine miRNAs in cancer cells. An interface for laser-induced fluorescence detection was firstly applied to perform the sample detection on the paper-based chip. Under the optimal conditions, DSN (3 mu L 0.10 U) and Taqman probes (2 mu L 2.5 x 10(-7) M) were preserved on the circles (Diameter 4 mm) of the folded paper chip. When miRNA solution was added, the mixed solution could trigger fluorescence signal amplification by cyclically digesting hybrids of miRNAs and Taqman probes by DSN. The whole determination, including sample heating process, could be accomplished within 40 min. The detection limits for miRNA-21 and miRNA-31 were 0.20 and 0.50 fM respectively, corresponding to only 1.0 and 1.5 zmol consumption of miRNAs. The testing of mismatched miRNAs showed that the method had good specificity. Finally, the method was applied to determine miRNA-21 and miRNA-31 in lysates of cancer cells of A549 and HeLa, and hepatocyte LO2. MiRNA-21 and miRNA-31 could be successfully found from the two cancer cells. The concentrations for miRNA-21 and miRNA-31 were 1.74 x 10(-13) M and 6.29 x 10(-14) M in HeLa cell lysate (3.75 x 10(4) cells/mL), 3.07 x 10(-15) M and 3.28 x 10(-15) M in A549 cell lysate (8.33 x 10(6) cells/mL) respectively. The recoveries ranged from 87.30% to 111.83%, indicating the results were reliable. The developed method was effective, selective and sensitive in the determination of miRNAs in cancer cells.
