	Abstract:The structures and stabilities of XSin-1- and X2Sin-2 (X = P, As) clusters have been investigated at the B3LYP level of theory, incorporating the 6-311+G* basis set. The results indicated that the ground state structures of PSin-1-/AsSin-1-/As2Sin-2 (isolobal to Sin2- and BnHn2-) could be obtained by the wade’s (2n+2) rule. Based on our computation study, the applicability of the design principle, wade’s (2n+2) rule, was further confirmed by exploring the lower-energy isomers of small P2Sin-2 (n = 5-9) clusters. The Wade’s (2n+2) rule should be very promising for predicting and rationalizing the stable structures of heteroatom-doped silicon clusters.

	Abstract:In this paper, we have introduced a simple strategy to prepare ZrO2 nanobamboos through an electrospinning method by using polyvinylpyrrolidone (PVP) as template and Zr(NO3)4 as precursor. Such ZrO2 nanobamboos could be used as the matrices for analysis of small molecules by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), because of their good capability to transfer ultraviolet energy to targeted molecules.

	Abstract:With the capability to inhibit the formation of amyloid-β peptides (Aβ) fibril, dopamine (DA) and other catechol derivatives have been considered for the potential treatment of Alzheimer's disease (AD). Such treatment, however, remains debatable because of the diverse functions of Aβ and DA in AD pathology. Moreover, the complicated oxidation accompanying DA has caused the majority of the previous research to focus on the binding of DA oxides onto Aβ. The molecular mechanism by which Aβ interacts with the reduction state of DA, which is correlative with the brain function, should be urgently explored. By controlling rigorous anaerobic experimental conditions, this work investigated the molecular mechanism of the Aβ/DA interaction, and two binding sites were revealed. For the binding of DA, Tyrosine (Tyr10) was identified as the strong binding site (Kd: 0.30 μmoloL-1), and SNK(26-28) segment was the weak binding segment (Kd: 2.92 μmoloL-1). Furthermore, THT fluorescence confirmed DA's positive function of inhibiting Aβ aggregation through its weakly binding with SNK(26-28) segment. Meanwhile, 7-OHCCA fluorescence exhibited DA's negative function of enhancing oOH generation through inhibiting the Aβ/Cu2+ coordination. The viability tests of the neuroblastoma SH-SY5Y cells displayed that the coexistence of DA, Cu2+, and Aβ induced lower cell viability than free Cu2+, indicating the significant negative effect of excessive DA on AD progression. This research revealed the potential DA-induced damage in AD brain, which is significant for understanding the function of DA in AD neuropathology and for designing a DA-related therapeutic strategy for AD.

	Abstract:In this present work, a simple regenerable electrochemical aptasensor for the parallel and continuous detection of protein biomarkers was reported. Mucin 1 protein (MUC1) and cinoembryonic antigen (CEA) were employed as the models of protein biomarkers. The sensing interface was modified by MUC1 aptamer and methylene blue (MB)-modified CEA aptamer via hybridization with a linker DNA. Herein, MB served as a signal transducer, MUC1 and CEA were parallel measured, and the detection limits of MUC1 and CEA were 0.13 nM and 2.75 ng mL-1, respectively. More significantly, the present biosensing interface can also be employed for the continuous detection of biomarkers. After the detection of MUC1, the resulted biosensing interface can be continuously used to measured CEA, and the detection limit was obtained as 0.5 ng mL-1, which was obviously lower than that based on the parallel analysis of CEA. Meanwhile, the aptasensor can be regenerated by rehybridization of DNA2 or DNA3-MB after the parallel detection targets, or by introducing MUC1 and CEA and then rehybridizing the MUC1 aptamer and CEA aptamer with linker DNA1 on the gold electrode. Therefore, it can be elucidated that this present strategy provides different protocols (parallel and continuous detection) to meet the requirements of analytical applications. This present method is also cost-effective and operating-simple comparing with the instrument-based methods for the multiplexed detection of markers. And the accuracy, simplicity and reproducibility of this biosensor was excellent. It will give a potential guidance for the multiplexed detection of biomarkers or other small molecules.

	Abstract:A diastereo- and enantioselective aldol reaction of tert-butyl isocyanoacetate with aldehydes was realized under metal-free phase-transfer catalytic conditions. Key to success was the use of a free 9-OH-containing cinchona alkaloid-based quaternary ammonium salt bearing bulky and electron-withdrawing aryl groups on the N-benzyl moiety. This process tolerates both aromatic and aliphatic aldehydes, affording the corresponding chiral oxazoline products in diastereoselectivities up to 20:1 and enantioselectivities up to 78% ee.

	Abstract:A series of Ni/Al2O3 catalysts were prepared using NiAl-CO3-layered double hydroxides (NiAl-LDHs) with different Ni/Al molar ratio (2:1~4:1) as precursors and studied in the hydrogenation of anthraquinone. The catalytic results show that Ni/Al2O3-2:1 catalyst exhibits highest hydrogenation activity due to the highest surface area. Moreover, different amount of lanthanum modified Ni/Al2O3-2:1 catalysts show higher hydrogenation activity. When the La loading reaches 2 %, the hydrogenation activity increases by 20.7 % and shows preferable selectivity compared with Ni/Al2O3-2:1 catalyst. Superior hydrogenation activity can be ascribed to the smaller Ni particle size and higher Ni dispersion. Preferable selectivity can be ascribed to the electronic effect of lanthanum, resulting in electron-rich Ni and weakening the adsorption of anthraquinone hydrogenation products. In addition, a new type of pores is generated during the calcination process, which is advantageous for the generated anthraquinone molecules to spread out to prevent overhydrogenation.

	Abstract:In this paper, the corrosion behavior of copper in HCl solution was investigated by surface analysis, weight loss and electrochemical measurements. Results show that corrosion products changed from 0.001 to 1 M HCl solution. The primary corrosion product is Cu2O in 0.001-0.01 M HCl solution, however, Cu2+ and a small amount of CuCl in 0.1-1 M HCl solution. It indicates that the corrosion mechanism of copper in different concentration of HCl is different. Domperidone was tested as a corrosion inhibitor for copper in different concentration of HCl solution using weight loss test, open circuit potentials (OCP), potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The experimental results revealed that corrosion rate of copper increased with the increment of HCl concentration from 0.001 to 1 M whether domperidone was added or not, and domperidone was a cathodic inhibitor in HCl solution, with a maximum achievable inhibition efficiency of 98.5% in 0.01 M HCl tested by EIS.

	Abstract:Biomass-derived porous carbons are widely regarded as one of the most promising electrode materials for supercapacitors owing to their natural abundance and low-cost. Herein, we present a facile approach to synthesize promising porous carbons via a two-step fabrication process using lotus seedpods (LS) as the biomass precursor. Firstly, the LS is hydrothermally treated in a KOH aqueous solution. After filtration and drying, the hydrothermal product is directly subjected to simultaneous pyrolysis and activation, giving LS-derived porous carbon materials. The morphology, structure and textural properties of the carbon materials are investigated by scanning electron microscopy, transmission electron microscopy, and N2 sorption isotherms. The porous carbon prepared under optimal conditions exhibits a relatively high BET surface area of 1813 m2 g-1 and an average pore size of 3.30 nm. Such porous carbon shows outstanding capacitive performance (402 F g-1 at 0.5 A g-1), good rate capability and excellent cycling stability (95.4% of capacitance retention after 10,000 cycles) in 6 M KOH electrolyte. More importantly, the as-assembled symmetric supercapacitor delivers a high energy density of 12.5 Wh kg-1 at power density of 260 W kg-1.

	Abstract: A signal-on photoelectrochemical sensing methodology for concanavalin A monitoring by coupling graphene-supported quasi-octahedral TiO2 mesocrystal with an efficient enzyme-free labeling strategy. Graphene with prominent conductivity enhancing the photocurrent response, NiCo2O4 labeling was proposed here accept the photo-induced electrons from conduction band of TiO2 mesocrystal, leading to the decrease of the photocurrent intensity. A signal-on non-enzymatic photoelectrochemical sensor was constructed based on immobilized concanavalin A competing with isolated concanavalin A of various concentrations for reaction with the NiCo2O4 labeled glucose conjugates, which opened a novel method for concanavalin A determination.
