Synthesis of different CuO nanostructures from Cu(OH) 2 nanorods through changing drying medium for lithium-ion battery anodes
Schematic illustration of synthesis processes of different CuO nanostructures by changing the drying medium.
Orange red emitting naphthalene diimide derivative containing dendritic wedges: aggregation induced emission (AIE) and detection of picric acid (PA)
Herein we report the synthesis, characterization and photophysical properties of novel naphthalene diimide (NDI) derivatives containing naphthalene units which are covalently attached to either end of the NDI.
Fabrication of high-performance composite electrodes composed of multiwalled carbon nanotubes and glycerol-doped poly(3,4-ethylenedioxythiophene):polystyrene sulfonate for use in organic devices
The organic doping facilitates the high performance of MWCNT/PEDOT:PSS composite electrode in organic devices.
Biological Niches within Human Calcified Aortic Valves: Towards Understanding of the Pathological Biomineralization Process
Despite recent advances, mineralization site, its microarchitecture, and composition in calcific heart valve remain poorly understood. A multiscale investigation, using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive X-ray spectrometry (EDS), from micrometre up to nano…
QM/MM studies reveal pathways leading to the quenching of the formation of thymine dimer photoproduct by flanking bases
It is known that the formation of the photochemical product of thymine-thymine cyclobutane pyrimidine dimer (TT-CPD) formed upon UV excitation in DNA is significantly affected by the nature of the flanking bases, and that the oxidation potential of the flanking base correlates with the quenching of TT-CPD formation. H…
Single-molecule magnet involving strong exchange coupling in terbium( iii ) complex with 2,2′-bipyridin-6-yl tert-butyl nitroxide
Intramolecular antiferromagnetic interaction in <bold>Tb-6bpyNO</bold> was confirmed by comparison with the magnetic properties of <bold>Tb-6bpyCO</bold> and <bold>Y-6bpyNO</bold> . <bold>Tb-6bpyNO</bold> showed a hysteresis loop below 1.6 K, but <bold>Tb-6bpyCO</bold> did not behave as a single-molecule magnet.
Chain entanglement and molecular dynamics of solution-cast PMMA/SMA blend films affected by hydrogen bonding between casting solvents and polymer chains
The effects of intermolecular interaction between casting solvents and polymer chains on molecular entanglement and dynamics in solution-cast PMMA/SMA films were probed by rheological, dielectric and modulated DSC methods.
Novel organic–inorganic hybrids based on T 8 and T 10 silsesquioxanes: synthesis, cage-rearrangement and properties
A simple approach for the synthesis of well-defined macromolecules based on isolated amino- and amido-functionalized octa T <sub>8</sub> and deca T <sub>10</sub> silsesquioxanes is presented. Here we show how the reorganization of the siloxane cage-like core (cage rearrangement) can be performed.
Photoresponsive and wetting performances of sheet-like nanostructures of tungsten trioxide thin films grown on wood surfaces
Tungsten trioxide films with sheet-like nanostructures coated on wood substrates possessed photoresponsive behavior and superhydrophobic performance after OTS treatment.
Quantum dot-layer-encapsulated and phenyl-functionalized silica spheres for highly luminous, colour rendering, and stable white light-emitting diodes
Although the quantum efficiencies of quantum dots (QDs) are approaching unity through advances in the synthesis of QD materials, their luminescence efficiencies after mixing with resin and thermal curing for white light-emitting diodes (LEDs) are seriously lowered because of aggregation and oxidation of QDs and poor a…
In vivo evaluation of small-molecule thermoresponsive anticancer drugs potentiated by hyperthermia
Hyperthermia used as an adjuvant with chemotherapy is highly promising in the treatment of certain cancers. Currently, the small molecule drugs used in combination with hyperthermia were not designed for this application. Herein, we report the evaluation of a chlorambucil and a ruthenium compound modified with a long…
A facile approach to synthesize an oxo-functionalized graphene/polymer composite for low-voltage operating memory devices
Polystyrene-derivative wrapped oxo-functionalized graphene, prepared by controlled chemistry, can be used as a floating gate in memory devices operating at 3 V.
Multilayered silicene: the bottom-up approach for a weakly relaxed Si(111) with Dirac surface states
Combining first principles investigations and scanning tunneling microscopy, we identify that the presumable van der Waals packed multilayered silicene sheets spontaneously transform into a diamond-structure bulk Si film due to strong interlayer couplings. In contrast to drastic surface reconstruction on conventional…
Luminescence properties of a new green afterglow phosphor NaBaScSi 2 O 7 :Eu 2+
A novel green afterglow phosphor NaBaScSi2O7:Eu(2+) was prepared by a solid state reaction under a reductive atmosphere. The NaBaScSi2O7:Eu(2+) phosphor shows two emission bands centered at about 424 (weak) and 502 nm (strong) due to the substitution of Eu(2+) in both Ba(+) and Na(2+) sites, and energy transfer from E…
Engineering of Sn–porphyrin networks on the silica surface: sensing of nitrophenols in water
Sn-porphyrin networks were engineered on the surface of a thin layer chromatography (TLC) plate via Sonogashira coupling of the Sn-porphyrin building block and 1,4-diiodobenzene. The Sn-porphyrin film showed a strong Soret band absorption at 422 nm, emission at 600-630 nm, and excellent sensing performance toward nitr…
Mechanical control of magnetism in oxygen deficient perovskite SrTiO 3
Mechanical control of magnetism in perovskite oxides is an important and promising approach in spintronics. Based on the first-principles calculations, we demonstrate that a negative pressure leads to a great enhancement of magnetic moment in deficient SrTiO3 with oxygen vacancies, whereas a positive pressure results…
