They can be doped with various types of compounds depending on their uses. The manufacturing technology also includes a method of polishing the preforms, thereby reducing the loss of signal in the fiber.

A process for preparing polymer composites containing the modified carbon nanotubes, the composite comprising a polymer-modified carbon nanotubes and its aplication

The object of invention relates to polymer composites containing the modified carbon nanotubes, the composite comprising a polymer-modified carbon nanotubes and its application used in the production of flexible heating mats.

The invention allows the manufacture of low-voltage heating mats resistant to mechanical and chemical damage, safe for the user. The resulting composite is very flexible and it is possible to roll it in the range from 0° to 360° and cut it freely, which makes it attractive in applications in floor heating, heating of car seats, operating tables, and clothing.

Microporous material and its preparation method

The object of invention is a microporous material and its method of preparation. The invention is applicable in many fields of technology, where materials with a very well developed free inner surface are used. The material, according to the invention, demonstrates morphological structure not yet described in the known publications. The inner core layer of fibers comprises of free spindle spaces with the size comparable to micrometer. These spaces are connected together in a continuous way with nano-channels. The outer layer of the fiber has the smooth form, without micropores, while ensuring the contact of micropores with the environment by the presence of the nano-channels. The fibers were obtained in an innovative way resulting in a very strong development of the free inner surface. Modification of the fibers causes a 25x increase in hydrophilicity, sorption properties in relation, for example, to metal ions of two or more valencies.

Properties of fibers obtained from their unique micro- and nano-porous structure enable them to be used in all types of filters in the household, as absorbents of metals in home water filters, heat insulating material in the disposable articles, etc. The fibers can be used in health care, especially of forestry workers and staff working in the field towards repellent securing of their clothing against ticks. It is possible to weld the fibres obtained in order to obtain electroconductive properties. The invention also allows to produce breathable films, providing directional transport of moisture.

A method for preparing a MnO2/carbon nanofibers composite for the preparation of the oxide electrodes and asymmetric electrochemical capacitor built based thereon.

The object of the invention is the method for preparing a MnO2/carbon nanofibers composite for the preparation of the oxide electrodes and asymmetric electrochemical capacitor built based thereon. The invention is applicable in the design of electrochemical capacitors.

An advantage of the composite, according to the present invention, is to improve the operating parameters of the electrochemical capacitor operating in a neutral electrolyte. The solution allows to work with a broader potential window (2.3 V) and to increase the capacitance, its power and energy while maintaining stability during cycling operation. The theoretical capacity of the MnO2 is very high (1370 F/g) and is associated with the use of loads originating from the chemical reaction of change and the degree of oxidation of manganese (pseudo-capacitance), but the disadvantage is a high electrical resistance. The solution to this problem was to design the composite, according to the invention, consisting of MnO 2 and carbon material having high electrical conductivity. This combination ensures high capacity and good conductivity of the material at relatively low costs.

The solution relates to a MnO2/carbon nanofibers composite having the characteristics of a pseudo-capacitance, which can be used as a positive electrode material in an asymmetric electrochemical capacitor operating in an aqueous medium. The key characteristic distinguishing discussed sollusion from the prior ones is the creation of a composite material using oxidized nanofibers. The distinguishing feature of the discussed invention is the use of carbon fiber with modified surface. Surface modification is very important for several reasons:

– Oxidized carbon nanofibers exhibit improved characteristics of the capacitance as compared to non-oxidized ones due to the pseudo-capacitance effect associated with the redox reactions of oxygenated groups.

– oxidation of nanofibers causes the change in the nature of the material from hydrophobic to hydrophilic, which facilitates the unraveling in aqueous solution;

– oxidation of the fibers leads to improved adhesion of the MnO2particles to the surface of carbon nanofibers, which allows better distribution of the manganese oxide in electrode material;

A method of high resolution fluorescence imaging and the use nanoluminophores doped with lanthanide ions for high resolution fluorescence imaging

The object of invention relates to a new high resolution fluorescence imaging and the use nanoluminophores doped with lanthanide ions for high resolution fluorescence STED (Stimulated Emission Depletion) imaging.

The most important innovation of present invention is to use the appropriate and not yet used combination of beams of light excting the fluorescent markers and the use of unique luminescent markers. These markers are in the form of nanoluminophores doped with rare earth ions, which absorb radiation from near-infrared range and have long lifetimes of excited levels, eliminating undesirable autofluorescence of the studied biological objects. Due to well-known and developed technology of lasers on solid-state object and semiconductor lasers and detectors in the field of visible and NIR radiation, it is possible to significantly simplify the measuring system and to use relatively cheap components. Using for excitation a 808 or 980nm near-infrared it is possible to image thick biological samples by a much smaller NIR light scattering which improves the signal to noise ratio, thereby increasing the sensitivity of the method. The fluorescent markers have a long lifetime, in the range of 10e-6 – 10e-3s, so it is possible to use the much simpler and cheaper semiconductor sources of continuous light (rather than extremely complex and tunable femtosecond pulsed lasers). These markers are further characterized by the absence of photobleaching, which allows for long-term observation, including study of the kinetics of biological processes. Moreover, the gap wavelength (i.e. Stokes shift) between exciting laser beam, quenching laser beam and the emission of light from the luminescent markers is more than 30nm, which can significantly simplify the detection system to the imaging system and increase its sensitivity.

A process for preparing the modified oxide varistors

The object of invention relates to creation of oxide varistors for protecting against overvoltage or an overload of electronic systems and power plants. According to the invention, the method assumes bismuth oxide to be replaced by lanthanide-barium-Bismuth oxide with reduced antimony and bismuth oxide. Such doping allows multiple reduction of the amount of heavy metals additives harmful to the environment. These additives also sublime during sintering destroying furnace lining and poisoning the atmosphere. The present invention increases the service life of furnaces for varistor making and a reduction of added components. The invention improves the performance characteristics of the varistor, the addition of a lanthanide oxide increases varistor’s energy consumption. An advantage of the invention is to accelerate the sintering process, which entails saving of electricity. The invention will also improve the microstructure of the varistor. Due to homogenization of microstructure, electrically inactive areas are being eliminated. Furthermore, this method of doping allows to skip additional stabilization heat improving the energy properties of the varistor which is reflected in an increase in energy consumption of up to 100 J/cm 3

Superluminescent diode based on AlInGaN

The object of invention is a superluminescent diode based on AlInGaN applicable in optoelectronics, photonics and fiber systems, and in particular as a source of 5 visible radiation.

The resulting spectrum has a higher spectral width and a smaller depth of spectrum modulation. It is also possible to apply 10 additional dielectric layers with a high coefficient of reflection (Bragg reflector). By increasing the reflectance of the rear window of the output waveguide what is achieved is reduction of the power emitted from the window, and at the same time increase of the power emitted from the front window.

Cascaded converter of ionizing radiation and imaging diagnostic device in real time

The invention relates to a cascade converter of ionizing radiation and imaging diagnostic device applicable to medical diagnostic devices and X-ray scanners for airport baggage control.

Cascade converter of ionizing radiation, according to the invention, and apparatus for diagnostic imaging using a cascade converter of ionizing radiation characterized by a simple structure, limiting the number of used components. Inventions enable imaging in real time and reading the result with the naked eye in transmission and reflectance mode. They are transparent to visible light, and through the use of indirect conversion, the thickness of the layers of first and second degree conversion was reduced. It favourably influences the sensitivity of detection of ionizing radiation and reduces the amount of ionizing radiation energy required for effective imaging, helping to reduce the negative impact of said radiation at the patient.

The method of treatment of phosphogypsum waste

The present invention relates to a process for treatment of phosphogypsum waste, in particular waste defaulting on landfill, applicable as raw material for cement production.

The invention allows to reduce the content of soluble phosphate and humidity of conditioned phosphogypsum to the level required by the cement producers. Moreover, it also requires the use of energy intensive technological machines and restricts the use of relatively expensive limestone powder, which in turn results in lower costs of producing of full value final product while reducing environmental pollution.
