(Ca,Sr)CO <sub>3</sub> :Eu <sup>3+</sup> vaterite, calcite and aragonite phases were obtained and exhibit various luminescent properties.
Heptamolybdate is used as a “molecular adaptor” to modulate the metal–organic coordination building units in the hydrothermal environment, with new polyoxometalate-induced hybrid assemblies isolated demonstrating good photocatalytic activity.
Detailed synchrotron simultaneous SAXS/WAXS investigation on crystallization induced layer-to-layer transitions of PEO- <italic>b</italic> -PLLA.
In this work, caraway or oregano essential oils were added to the cast chitosan film in an attempt to design a natural, biodegradable, bioactive (antioxidant and antimicrobial) packaging film. When the structure of the tested films was analyzed with Fourier transform infrared spectroscopy, no significant differences w…
The Förster resonance energy transfer between CdSe quantum dots with two different sizes has been studied in an organic solvent upon the formation of close-packed aggregates of quantum dots, with the aggregation being both spontaneous and induced by a precipitating solvent. The addition of a precipitant has been estab…
H 2 is considered to be a clean, efficiently and renewable energy because H 2 O is the only product when H 2 combines with O 2 . The splitting of water into H 2 and O 2 by sunlight is viewed as one of the most promising ways to produce clean and sustainable energy that is expected to meet the future need as environmen…
Dual-scale structures showing superhydrophobic characteristics have been fabricated using sublimable smectic liquid crystals.
Electropolymerization of aniline at the graphite electrodes was achieved by potentiodynamic method. Electrodeposition of Pd (C‐PANI‐Pd) and Ni (C‐PANI‐Ni) and codeposition of Pd‐Ni (C‐PANI‐Pd‐Ni) microparticles into the polyaniline (PANI) film coated graphite (C‐PANI) were carried out under galvanostatic control. The…
A novel tetraphenylethene–carbazole type compound containing the dimesitylboron moiety with aggregation-induced emission enhancement properties was synthesized and utilised as a blue light-emitting material in OLED devices.
Perovskite-type manganites, such as Pr1-xCaxMnO3, La1-xCaxMnO3 and La1-xSrxMnO3 solid solutions, are set forth as a case study of ferroelectricity formation mechanisms associated with the appearance of site- and bond-centered orbital ordering which breaks structural inversion symmetry. Even though the observation of m…
A facile synthesis of homogeneous Ag nanostructures on modified polypyrrole (PPy) films through direct chemical deposition has been demonstrated. The as-prepared Ag nanostructures are highly sensitive and reproducible in the SERS detection of the target analyte, methylene blue (MB).
Development of biodegradable polymers-based scaffolds for tissue engineering is a promising trend in bioengineering. The electrospun scaffolds from poly(3-hydroxybutyrate) (PHB) were produced using different additives that changed the physical and chemical characteristics of the products. As a result, the construct co…
Many DNA scaffolds efficiently encapsulate highly emissive silver nanoclusters (AgNCs). The secondary structures and the arrangement of sequences of DNA scaffolds are important factors by which the specific features of AgNCs emitters can be determined. By introducing DNA-RNA chimera scaffolds, we here explore another…
The effect of Zn on side-chain alkylation of toluene with methanol over KX zeolite was investigated. It was found that the addition of Zn with a low content over KX could enhance toluene conversion significantly. In addition, the results showed that the conversion of toluene over ZnKX (0.8 wt. %) catalyst was almost t…
A broad size range of cuprous oxide (Cu2O) nanocubes from 36 nm to 450 nm are obtained by an in situ seed-mediated approach that simply requires two additions of deionized water. The as-prepared Cu2O nanocubes are found to have strong antibacterial activity towards both Gram-negative and Gram-positive bacteria.
Free of external disturbance, Ca <sup>2+</sup> ions stack in the (0001) faces in the mode of (a), corresponding to thermodynamically least stable vaterite phase. To maximally reduce coulomb repulsion under external agitation, one Ca <sup>2+</sup> ion moves up and the other moves down for one third of interplanar cryst…
Mesoporous colloidal spheres consisting of LaF <sub>3</sub> :Yb,Er/Tm nanoplates are developed, showing tunable upconversion emissions under NIR excitation through dye loading.
Seven gelator molecules giving supramolecular gels produced Au-nanoparticles and fluorescent, small Au-nanoclusters. Such Au-nanoparticle containing gels catalyzed the reduction of <italic>p</italic> -nitrophenol to <italic>p</italic> -aminophenol without NaBH <sub>4</sub> . The fluorescent Au-nanoclusters acted as a…
The effect of a deep cryogenic treatment on the microstructure of a super-bainitic steel was investigated. It was shown that quenching the super-bainitc steel in –196°C liquid nitrogen resulted in the transformation of retained austenite to two phases: ~20 nm thick martensite films and some nano carbides with a ~25 nm…
The regeneration pathway of sodium alanate has been studied by <italic>in situ</italic> synchrotron powder X-ray diffraction and powder neutron diffraction.
