摘要:
Novel imidazolium salts of formula (I) are described in which R is a C 1 -C 14 alkyl group, optionally substituted by one or more fluorine atoms, or a C 2 -C 18 alkoxyalkyl group, R' is an alkyl group containing at least 8 carbon atoms, at least 6 of which are partially or entirely fluorinated, R" is hydrogen or C 1 -C 3 alkyl, Z is an organic or inorganic anion, and Q is further defined. The compounds of formula (I) are liquid crystals over a wide temperature range, and are characterised by high conductivity, hydrophobicity and stability. These properties made them ideally suitable for use in devices based on electrochemical reactions, such as solar cells, fuel cells, electrochemical sensors, lithium batteries and capacitors, etc.
摘要:
The invention describes a composition for sealing agent, generally in the form of glass frit, lead-free, comprising by weight over the total weight of the composition: 30-80% Bi2O3; 2- 10% ZnO; 2- 10% B2O3; 0-5% Na2O; 1- 10% SiO2; 1-8% A12O3; 0-7% BaO; and 0-8% MgO. The composition for sealing agent as defined above can be added with a filler in a quantity up to 20% by weight over the total weight of the resulting mixture. It also describes a sealing paste containing the composition for sealing agent, the possible filler, an organic binder and optionally an organic solvent. It also describes methods for producing the composition for sealing agent and the sealing paste.
摘要:
New electrolyte gels based on quaternised and non-cross-linked linear copolymers according to formula (I), having high efficiency and stability. Further described are the method of production of the said gels, their use in the preparation of photoelectrochemical devices and the devices manufactured therewith.
摘要:
The present invention relates to a process for the preparation of materials with nanometric dimensions and controlled shape, based on titanium dioxide. The invention also relates to a process for the preparation of titanium dioxide nanorods and nanocubes with anatase phase composition, which are highly suitable for photocatalytic use, in particular for applications involving photovoltaic cells, for example Dye Sensitized Solar Cells (DSSC), photoelectrolysis cells and tandem cells for the conversion of solar energy and the production of hydrogen.
