Tunable full-color dual-state (solution and solid) emission of push-pull molecules containing the 1-pyrindane moiety.

A facile method for the synthesis of arylidene derivatives of pyrindane - ()-7-arylmethylene-2-chloro-6,7-dihydro-5-cyclopenta[]pyridine-3,4-dicarbonitriles - was developed. Tunable full-color emission was achieved for the synthesized push-pull molecules, solely by changing donor groups while keeping both the conjugated system and acceptor part of the molecule unchanged. This represents a rare approach for the design of such fluorophores.

Synthesis of the first 4-oxobutane-1,1,2,2-tetracarbonitriles containing a phenol fragment and their transformation into cyano-substituted pyrrol-2-ones showing three-position molecular switching.

The first example of the synthesis of 4-oxobutane-1,1,2,2-tetracarbonitriles (OTCs) containing a phenolic moiety has been described. The synthesis is based on the reaction between tetracyanoethylene and 4-hydroxyphenyl-substituted ketones under mild conditions. Due to the presence of a phenolic hydroxyl group, these compounds are more functionalized derivatives of the well-known OTC substrates used for diversity-oriented synthesis (DOS).

Tunable full-color emission of stilbazoles containing a 2-halo-3,4-dicyanopyridine acceptor.

Synthesis of a series of novel push-pull stilbazole-based chromophores containing a strong 2-halocinchomeronic dinitrile acceptor is reported. The photophysical properties of the compounds are described. Strong positive solvatofluorochromism typical of intramolecular charge transfer (ICT) dyes is observed for the synthesized stilbazoles.

Effect of a Substituent in the Fourth Position on the Optical Properties of 2-Oxonicotinonitriles.

Based on six representatives of 2-oxonicotinonitriles, the effect of the nature of the substituent in the fourth position of the pyridine system on the photophysical characteristics was studied. The role of the donor/acceptor nature of the substituent and the solvent nature in the absorbing and fluorescent properties of the compounds was shown.

Popularization of Carbon Capture and Storage Technology in Society: Principles and Methods.

The problem of global warming is a key challenge. One means to prevent climate change is to reduce the concentration of carbon dioxide in the atmosphere. This can be achieved using CO capture and storage (CCS) technology.

Public perception of carbon capture and storage: A state-of-the-art overview.

Carbon capture and storage (CCS) is a technology enabling to use fossil fuels in a sustainable way. Therefore, it attracts much attention from the industrial sector, government authorities and scientific community. However, public awareness of the technology is extremely low, and the studies of the lay people's opinion have been launched only during the last decade.

Field dependence of the ferromagnetic/superconducting proximity effect in a YBCO/STO/LCMO multilayer.

The interaction between superconductivity and magnetism in spatially confined heterostructures of thin film multilayers is investigated in the ferromagnetic manganite La2/3Ca1/3MnO3 (LCMO) and the high-temperature superconductor YBa2Cu3O7-δ (YBCO) mediated by an intermediate insulating SrTiO3 (STO) layer. The STO layer is used to mediate and tune the range of interactions between the ferromagnet and superconductor. A magnetically depleted layer with zero-magnetisation within the LCMO layer is shown by polarised neutron reflectometry measurements.

Observation of Transient Overcritical Currents in YBCO Thin Films using High-Speed Magneto-Optical Imaging and Dynamic Current Mapping.

The dynamics of transient current distributions in superconducting YBaCuO thin films were investigated during and immediately following an external field ramp, using high-speed (real-time) Magneto-Optical Imaging and calculation of dynamic current profiles. A number of qualitatively unique and previously unobserved features are seen in this novel analysis of the evolution of supercurrent during penetration. As magnetic field ramps up from zero, the dynamic current profile is characterized by strong peaks, the magnitude of which exceed the conventional critical current density (as determined from static current profiles).

Analysis of low-field isotropic vortex glass containing vortex groups in YBa2Cu3O(7-x) thin films visualized by scanning SQUID microscopy.

The glass-like vortex distribution in pulsed laser deposited YBa2Cu3O(7-x) thin films is observed by scanning superconducting quantum interference device microscopy and analysed for ordering after cooling in magnetic fields significantly smaller than the Earth's field. Autocorrelation calculations on this distribution show a weak short-range positional order, while Delaunay triangulation shows a near-complete lack of orientational order. The distribution of these vortices is finally characterised as an isotropic vortex glass.

Large, controllable spikes of magnetoresistance in La(2/3)Ca(1/3)MnO3/SrTiO3 superlattices.

We have investigated superlattices consisting of up to 30 epitaxial nanomultilayers (3-7 nm thick) of ferromagnetic La(2/3)Ca(1/3)MnO(3) (LCMO) and insulating SrTiO(3) (STO) hybrids. The superlattices demonstrate dramatic shifts of Curie temperature, indicating the possibility of its tunability. The metal-insulator transition (MIT) has been observed around 140 K.

[Analysis of hospital mortality related to alcoholic intoxication and alcoholism for 1991-1993 (according to autopsy results)].

The conclusion is made about the permanent growth of the percentage of lethal cases connected with alcoholism, particularly in 1993. Among persons dying from alcoholism the percentage of young people and women is increased. Several unusual cases are described.

[Case of metastatic uterine leiomyoma in a 74-year-old woman].

The uterus with appendages was removed 28 years ago because of ordinary leiomyomatosis, but large metastatic nodes in both lungs were persistent for more than 30 years until the patient death. This variant of secondary pulmonary pathology should be distinguished from pulmonary lymphangioleiomyomatosis--a primary pathological process having its own clinicomorphological features.

[A case of intravenous leiomyomatosis of the uterus in pregnancy].

A description of one case: 32-year-old woman with undiagnosed pregnancy (2-3 months) was operated on for uterine intravenous leiomyomatosis falsely diagnosed by gynecologists as sarcoma. This benign tumor is a rare condition with a characteristic morphology and must be distinguished from another relative tumour of the uterus--so-called metastasizing benign leiomyoma.
