A new pyrene based fluorescence probe has been synthesized for fluorogenic detection of Cu(2+) in acetonitrile-aqueous media (7 : 3 CH3CN-HEPES buffer, v/v, at pH 7.5) with bioimaging in both prokaryotic (Candida albicans cells) and eukaryotic (Tecoma stans pollen cells) living cells. The anion recognition properties…
A facile and economical MoSe2/Mo structure was in situ prepared to replace the currently preferred expensive Pt and FTO counter electrode (CE) in dye-sensitized solar cells. A power conversion efficiency of 8.13% was achieved, which is comparable to that with Pt-sputtered FTO electrode (8.06%).
CS–PWA–Nafion composite membranes were successfully synthesized via a layer-by-layer self-assembly technique. They exhibited low vanadium ion permeability and improved comprehensive performance in VRFBs.
Development of stable and recyclable solid acid catalysts in the efficient valorisation of hemicellulose to yield C5 sugars and furfural is vital to boost the prospects of using lignocelluloses for chemicals synthesis. Using an silicoaluminophosphate, namely SAPO-44, as a catalyst, an environmentally benign process of…
Photothermal therapy (PTT) is limited by unsuitable photothermal agents and near-infrared (NIR) light. Herein, self-assembled PEGylated WO3-x hierarchical nanostructures, which could serve as excellent laser-cavity mirrors, were successfully prepared via a simple one-pot solvothermal route. The as-prepared WO3-x hiera…
A method for achieving complete pore-filling in solid-state dye-sensitized solar cells termed melt-infiltration is presented: after the customary solution-processed deposition of spiro-OMeTAD, the device is heated above the glass transition temperature of spiro-OMeTAD to soften the material and allow capillary action…
Despite numerous analytical studies, the exact nature of the mineral component of bone is not yet totally defined, even though it is recognized as a type of carbonated hydroxylapatite. The present study addresses the hydration state of bone mineral through Raman spectroscopic and thermogravimetric analysis of 56 sampl…
Silica-coated magnetite (Fe 3 O 4 @SiO 2 ) nanoparticles functionalized with amino, imino and sulfonic groups (Fe 3 O 4 @SiO 2 –mPD/SP) were successfully synthesized via a facile chemical oxidative polymerization of m -phenylenediamine (mPD) and m -sulfophenylenediamine-4-sulfonic acid (SP) monomers, and utilized for…
It is a worldwide challenge to efficiently separate surfactant-stabilized oil–water emulsions.
This work reports the use of 9,9′-spirobifluorene and 4-phenyl-9,9′-spirobifluorene, pure hydrocarbon small molecules, as hosts for efficient green and blue phosphorescent OLEDs.
Zero-dimensional Fe2O3 nanoparticles were successfully decorated on three-dimensional WO3 architectures to constitute a photocatalyst of Fe2O3@WO3 heterojunction. The obtained samples were characterized in detail by X-ray diffraction, scanning electron microscopy, elemental mapping, X-ray photoelectron spectroscopy an…
Synthesis of novel furan-containing tetrafunctional fluorene-based benzoxazine monomer and its high performance thermoset.
At present, designing novel ligands for efficient actinide extraction in spent nuclear fuel reprocessing is extremely challenging due to the complicated chemical behaviors of actinides, the similar chemical properties of minor actinides (MA) and lanthanides, and the vulnerability of organic ligands in acidic radioacti…
The results of an experimental investigation on the mechanical properties of molybdenum disulphide (MOS2, also called molydisulphide) powders reinforced in aluminium alloy (Al-2024) composite samples are reported in this paper. MOS2 powders of approximately 40 μm particle size were reinforced in an aluminium alloy mat…
A new family of fluorescent synthetic molecular probes for nitric oxide sensing based on ortho-hydroxyamino-triarylpyrylium salts is presented.
The present report describes the syntheses, characterizations, crystal structures and study of the phenoxazinone synthase activity of two peroxo-bridged dicobalt(III) complexes, [Co2(L(1))2(μ-O2)](ClO4)4·2CH3CN (1) and [Co2(L(2))2(μ-O2)](ClO4)4 (2), and three mononuclear cobalt(II) complexes, [Co(L(3))(CH3CN)](ClO4)2…
Analysis of the strengths and directionality of intermolecular interactions in the crystals containing only one type of supramolecular synthon allows the suggestion of a general classification of molecular crystals depending on type of their basic structural motifs. All crystals may be divided on four classes namely (…
The tendency for an interaction to occur in crystal structures is not a simple function of its calculated energy in vacuo .
Neutron reflectometry analysis methods for under-determined, multi-layered structures are developed and used to determine the composition depth profile in cases where the structure is not known a priori. These methods, including statistical methods, sophisticated fitting routines, and coupling multiple data sets, are…
We compared conventional microscope-based methods for quantifying biomass and community composition of stream benthic algae with output obtained for these parameters from a new instrument (the BenthoTorch), which measures fluorescence of algal pigments in situ. Benthic algae were studied in 24 subarctic oligotrophic (…
