A photo-healable rubber composite based on effective and fast thiol–alkyne click chemistry as a self-healing agent prestored in glass capillaries is reported. The click reaction and its effect on the mechanical properties of the composite are monitored in real time by dynamic mechanical analysis, showing that the succ…
Nitrogen-doped (N-doped) single-wall carbon nanotubes (SWCNTs) were synthesized by chemical vapor deposition using SiOx nanoparticles as a catalyst and ethylenediamine as the source of both carbon and nitrogen. The N-doped SWCNTs have a mean diameter of 1.1 nm and a narrow diameter range, with 92% of them having diame…
We synthesized Co(OH) <sub>2</sub> /graphene composites from graphite without a graphene oxide (GO) step. The Co(OH) <sub>2</sub> /graphene composite exhibited a specific capacitance of 960 F g <sup>−1</sup> at a current density of 10 A g <sup>−1</sup> .
A new family of (Z)-3-(quinolin-2-ylmethylene)-3,4-dihydroquinoxalin-2(1H)-one derivatives, which exhibit aggregation-induced emission (AIE) activity, is synthesized and characterized. The qualitative structure property analysis reveals that the emission behaviors of these compounds are closely related to the location…
A series of early transition metal corrole complexes has been prepared via salt metathesis with the corresponding lithium corrole. Their characterization by single crystal X-ray diffraction, NMR, and absorption spectroscopy is described. Organometallic derivatives of the titanium complex were obtained via treatment of…
In this paper, the chiral surfactants bearing two long alkyl chains with hydroxyl groups at their terminals were synthesized and employed to encapsulate a catalytically efficient polyoxometalate through electrostatic interaction. The obtained chiral surfactant-encapsulated polyoxometalate complexes, in which a defined…
Boehmite nanostructures with different morphologies were prepared through polymorphic transformation of bayerite in the dry-gel conversion process with acetic acid solutions as steam source. The evolution of the crystalline structures and morphologies of nanoparticles tightly relied on the composition of the steam sou…
Bioactive glass-introduced gelatin/chitosan nanofibrous dressings were developed <italic>via</italic> electrospinning to endow improved antibacterial activity, adjustable bioactivity and water uptake capacity for enhancing chronic wound healing.
By improving interfacial interaction and forming CNT network structure, the fracture resistance of immiscible PC/PLLA blend is significantly enhanced.
Design and synthesis of fourteen new bent shaped luminescent mesogens carrying a pyridine core with various polar substituents are reported.
Magneto-electric/dielectric and photoemission of BTZF composites depends upon shape, size, surface spin, distortion, epitaxial strain <italic>etc.</italic> of nanostructure
ZnO nanopinecone arrays exhibit much better photocatalytic properties for the photodegradation of phenol in sunlight.
The composition of Sr <sub>2</sub> Fe <sub>1.5</sub> Mo <sub>0.5</sub> O <sub>6−δ</sub> , a SOFC electrode material, is investigated by neutron diffraction in both highly oxidizing and reducing conditions, and correlated with measured physical properties.
The famous Kissinger's kinetic evaluation method (Anal. Chem. 1957) is examined with respect to the feasible impact of the individual quantities and assumptions involved, namely the model of reaction mechanism, f(a) (with the iso- and nonisothermal degrees of conversion, ? and ?) the rate constant, k(T) (and associate…
We develop a bulk silver tip for tip-enhanced Raman scattering (TERS) and obtain TERS spectra of epitaxial graphene on the carbon face of 4H-SiC(000-1) with a high signal-to-noise ratio. Thanks to the high quality of TERS spectra we firstly find that the G band in the TERS spectra exhibits position-by-position variati…
Self-assembling systems of colloidal spheres are widely used as templates for the structured deposition of metals and semiconductors. Multilayer samples of ordered polystyrene spheres are prepared by a flow induced process. The subsequent surface activation by a dielectric barrier discharge in oxygen is followed by th…
Porous MgO–CaO–SnOx nanocubes (crystalline SnOx and amorphous MgO/CaO) were synthesized to implant firmly and uniformly onto in situ formed carbon paper by a facile route including a template-free growth process and calcining treatment. Low-cost filter paper was used to realize the part implantation of cubes as well a…
This study deals with the preparation and characterization of elastomeric nanocomposites from renewable resources for vibration damping applications.
The conformations of a series of benziporphyrins, naphthiporphyrins, oxybenziporphyrins, and related structures were minimized using DFT-B3LYP/6-311++G(d,p). The relative stabilities of the tautomers for each series were calculated using M06-2X and B3LYP-D functionals, and bond lengths were obtained. The diatropic pro…
In the first step to obtain an efficient nano-antenna in a bottom-up approach, new hybrid materials were synthesized using a set of layered double hydroxides (LDHs) with basic properties and pure chlorophyll a (Chl a). The stability of the adsorbed monolayer of Chl a was shown to be dependent on the nature and the rat…
