Developing ultrasensitive Raman nanoprobes is one of the emerging interests in the field of biosensing and bioimaging. Herein, we constructed a new type of surface-enhanced resonance Raman scattering nanoprobe composed of an Ag nanoshell as a surface-enhanced Raman scattering-active nanostructure, which was encapsulat…
The ordered hexagonal mesoporous silica (SBA-15) encapsulated ammonium molybdophosphate (AMP) was successfully synthesized using low-grade natural clay from Qaidam Basin as silica and aluminum source, through a one-pot synthesis method.
In this study, branched poly(ethyleneimine), BPEI, was synthesized from carboxylic acid terminated multi-walled carbon nanotubes (c-MWNTs) and characterized using FTIR, TEM and TGA. The BPEI was then chemically grafted onto MWNTs to enhance the interfacial adhesion with the epoxy matrix. The epoxy composites with c-MW…
An approach for the transformation of formyl groups into areneimidazoles at a porphyrin substrate is developed, allowing straightforward design of new polytopic porphyrinoid compounds.
We report a new, surfactant-free method to produce Co <sub>3</sub> O <sub>4</sub> nanocrystals with controlled sizes and high dispersity by caging templation of nanoporous networks.
With a purpose of solidifying fluorous solvents, a novel series of perfluorinated gelators based on 1,2-diaminocyclohexane (denoted as <bold>CFn</bold> : <italic>n</italic> = the number of carbon chain in perfluoroalkanoyl moiety) were developed.
Manganese(III) complexes of tetradentate diphenolate-diamino (NNOO(2-)) ligands were prepared from aerobic reaction of MnCl2 with the respective ligands in basic methanolic solution. Methoxide complexes (NNOO)Mn(OMe)(MeOH)0-1 were obtained for three ligands, while others only provided the respective chloride complexes…
Hyperbranched poly(triazole) bearing oligo(ethylene glycol) terminal groups is dual stimuli-responsive to thermal conditions and metal ions and is capable for the selective absorption of Ag <sup>+</sup> ion on tuning temperature.
There has been huge research interest in the energy gap problem of monolayer and bilayer graphene due to their great potential in practical applications. Herein, based on first-principles calculations, we report a promising way to open a large band gap in bilayer graphene (BLG) by sandwiching it between two substrates…
A novel thermo and pH dual-controlled charge reversal PSMA <sub>89</sub> - <italic>g</italic> -P(DMA <sub>16</sub> - <italic>co</italic> -SD <sub>56</sub> ) graft copolymer micelle was developed with effectively enhanced cellular uptake for overcoming multi-drug resistance in cancer cells.
A methanol solution of a series of simple esters exhibited a response to different alkali bases, which formed solutions, organogels and crystals, respectively, when LiOH, NaOH and KOH were separately introduced.
Jeremy Baumberg opened a general discussion of the Introductory Lecture by Mark Brongersma: Can you see the dynamics of the forming process of these Ag nanowires in real time using EELS? Mark Brongersma answered: This is a great question. We have not yet been able to see the form
Rattle-type NiCo <sub>2</sub> O <sub>4</sub> –carbon composite microspheres with a self-assembled shell were synthesized by a template method, which exhibited superior capacitive performances.
The synthesis of a range of rhodium(iii) and iridium(iii) half sandwich complexes with aryl dithiolato ligands of varying geometry and flexibility are reported. These include dinuclear [Cp*M(S-R-S)]2 complexes 3b and 4b, M = Rh, Ir; S-R-S = naphthalene-1,8-dithiolate (b) and four dinuclear complexes bearing bridging d…
Renewable based poly(urethane–urea) coatings with high thermal stability ( <italic>T</italic> <sub>g</sub> – 124.9) were prepared from hyperbranched polyester polyol with the degree of branching almost equal to 66%.
Based on Brownian Dynamics computer simulations in two dimensions we investigate aggregation scenarios of colloidal particles with directional interactions induced by multiple external fields. To this end we propose a model which allows continuous change in the particle interactions from point-dipole-like to patchy-li…
In Finsler geometry, each point of a base manifold can be endowed with coordinates describing its position as well as a set of one or more vectors describing directions, for example. The associated metric tensor may generally depend on direction as well as position, and a number of connections emerge associated with v…
A novel nano-bio composite of chitosan and a layered double hydroxide elegantly synthesized by a co-precipitation method had effectively and selectively catalysed the jasminaldehyde synthesis.
In this work, we show that grafted metal oxide can be a highly cost-effective and active anode for solid oxide fuel cells for sour methane conversion.
Oligopeptide-based derivatives are important synthons for bio-based functional materials. In this article, a Gly-(L-Val)-Gly-(L-Val)-coumarin (GVGV-Cou) conjugate was synthesized, which forms 3D networks in ethanol. The gel nanostructures were characterized by UV-vis spectroscopy, FT-IR spectroscopy, X-ray diffraction…
