The possible mechanisms of the surface topography formation and their features are discussed.Glycosylation is an important part of cell signalling that is implicated in many disease states in which glycans play an essential role. Therefore rapid and sensitive differentiation of glycans on proteins is highly desirable. Current technologies for glycan structural analysis normally involve the isolation of glycans from proteins, or enrichment of glycopeptides, and detection by mass spectrometry, which requires relatively large amounts of sample and is not able to be used by non-specialist laboratories. Herein we present a simple and new strategy for targeting the glycans on a protein (with IgG as a model glycoprotein) using surface-enhanced Raman scattering (SERS) coupled to glycan-binding WGA (wheat germ agglutinin) lectin, in a lectin-SERS assay. With one drop (1 μL) of glycoprotein solution, our lectin-SERS assay can detect as low as 10 ng IgG within two hours with high glycan specificity. We extend our technique to examine the surface glycan profiles on two human colorectal cancer cell lines, which show different and unique glycan signatures specific to the target cell lines. Thus, we believe that this method could be potentially used for the real-time and in situ monitoring of glycans on the surface of cells or tissue or in body fluids, and is thus a powerful tool for glycomics research.Interfacial properties of binary fluid mixtures were studied using both molecular dynamics (MD) simulations and density gradient theory (DGT). The focus of the study is on the relation of the interfacial properties to the phase diagram of the mixture. Two binary Lennard-Jones mixtures were investigated in a wide range of states a highly asymmetric mixture (type III), which exhibits vapour-liquid equilibria (VL1E and VL2E), liquid-liquid equilibria (L1L2E), a three-phase equilibrium (VL1L2E), and supercritical fluid-fluid equilibria (F1F2E), and, as a reference, an ideal mixture (type I). The studied interfacial properties are the surface tension, the relative adsorption, the width of the interfacial region, and the enrichment of the low-boiling component, on which we set a focus. Enrichment was observed at VL1 interfaces; and, to a small extent, also at L1L2 interfaces; but not at the supercritical F1F2 interfaces. The large enrichment found at VL1 interfaces of the type III mixture can be interpreted as a wetting transition approaching the VL1L2E three-phase line from the VL1 side, the enrichment gets stronger and can be interpreted as precursor of the second liquid phase L2. However, the actual existence of a three-phase line in the phase diagram is no prerequisite for an enrichment. The enrichment is found to be highly temperature-dependent and increases with decreasing temperature.Five 3D network Ln3+ metal-organic frameworks (Ln-MOFs) formulated as [[Ln(μ6-H2cpboda)(μ2-OH2)2]·xH2O]n [Ln3+ = La3+ (1), Nd3+ (2), Sm3+ (3), Eu3+ (4), Tb3+ (5), H2cpboda = 5,5'-((5-carboxy-1,3-phenylene)bis(oxy))diisophthalic acid] were synthesized via a hydrothermal method. They were established by single-crystal X-ray and powder diffraction analyses, elemental analysis (EA) and thermogravimetric analyses (TGAs). All the compounds are isostructural with three-dimensional structures with the point symbol of (413·62)(48·66·8) in terms of topology, and they crystallize in the monoclinic space group P21/n. Interestingly, the solid-state luminescence of complexes 4 and 5 shows intense red and green emission, respectively. Besides, the Tb-MOF (5) is a good luminescent sensor, able not only to detect aspartic acid and Fe(iii) ions with good stability, high efficiency and reversibility, but also to exhibit a rapid response and high selectivity to DMSO. To our knowledge, it is the first Ln-MOF that can act as a luminescent probe for the efficient sensing of DMSO, while the lone pair of electrons in the O of DMSO attacked the positive charge at the protonation carboxylic acid of H5cpboda. Consequently, Tb-MOF (5) is a rare and versatile fluorescent probe for aspartic acid, Fe3+ cations and DMSO, simultaneously.C-H activation is of great significance in the chemical industry while an effective solvent-free catalyst is highly desired. This work shows that a gold nanoisland which was inert in the bulk is effective for C-H activation reactions. Liothyronine in vitro We investigated the C-H activation of toluene on an Au nanoisland (58 atoms) using relativistic density functional theory (DFT). We found that (i) the bonds between under-coordinated gold atoms (corner site) shrink spontaneously and become stronger; (ii) the valence charges of corner atoms are polarized to the upper edge of the valence band (near the Fermi level), indicating the electron donation ability in the catalytic process; (iii) during C-H oxidation, the indirect path (O2 dissociation and O-H bonding) and direct path (O2-H bonding) were considered. The Au-O2 complex is active enough to abstract a hydrogen atom directly from toluene, with a barrier that is 6.8 kcal mol-1 lower than that of the indirect path; and (iv) a transfer of up to ∼0.8 electrons from gold to O2 occurs. Moreover, hybridization between delocalized gold orbitals and oxygen p-orbitals leads to the stabilization of the singlet spin state of Au58O. Our results suggest that undercoordination-charge-polarization are key factors for the C-H oxidation catalyzed by an Au nanoisland.The different polymorphic phases of transition metal dichalcogenides (TMDs) have attracted enormous interest in the last decade. The metastable metallic and small band gap phases of group VI TMDs displayed leading performance for electrocatalytic hydrogen evolution, high volumetric capacitance and some of them exhibit large gap quantum spin Hall (QSH) insulating behaviour. Metastable 1T(1T') phases require higher formation energy, as compared to the thermodynamically stable 2H phase, thus in standard chemical vapour deposition and vapour transport processes the materials normally grow in the 2H phases. Only destabilization of their 2H phase via external means, such as charge transfer or high electric field, allows the conversion of the crystal structure into the 1T(1T') phase. Bottom-up synthesis of materials in the 1T(1T') phases in measurable quantities would broaden their prospective applications and practical utilization. There is an emerging evidence that some of these 1T(1T') phases can be directly synthesized via bottom-up vapour- and liquid-phase methods.
