L'viv Polytechnica State University (LPSU), which was founded in 1844, has 1,650 teachers and 18,320 students. The university has 61 specialties for postgraduate education among 18 different faculties. It has about 100 different research laboratories, which are supported by 100 doctors of science (senior scientists) and nearly 2,000 junior scientists with Ph.D.s. It has collaborative relations with a number of universities, institutes, and businesses in foreign countries.
The WTEC team's visit to LPSU was only a few hours long, and consisted of a colloquium in which faculty presented brief discussions of research directions in their departments which they felt pertained to advanced display technology. The colloquium was followed by a tour of an extensive museum that showed hundreds of industrial products that had been developed through the original or advanced designs of LPSU scientists and engineers. The products showed a tendency for excellence in chemistry and chemical engineering, with lesser representation from other engineering disciplines. Tables Poly.1, Poly.2, Poly.3 and Poly.4 (re-typed from translations provided by the hosts) describe ongoing activities at the University.
The following research was reported by research department heads in a brief colloquium:
LPSU's laser research has several themes and goals. One effort is to get higher energy lasers, of shorter wave length, of better construction, in one-half the current requirements for physical size. A goal of creating a semiconductor laser was mentioned. Research of the mathematical design of interaction for laser radiation with materials was ongoing. Use of lasers to synthesize new materials, as well as laser etching and deposition of materials, were being explored.
Research in this area involved solid solutions of Hg:CdTe; this was mentioned briefly in the materials.
There was extensive interest in the Organic Chemistry Laboratory in
two technologies for liquid crystal displays. Research in hydrogen
peroxide groups enabled the generation of free radicals and the
deposition of definite monomers on a substrate. In addition, a
production capability for microspheres with different optical
characteristics for use in certain types of LCDs had been demonstrated.
The laboratory chief reported that the laboratory's process could
produce batches of spheres in solution much more cheaply than the
methods presently used in the United States. Table

Interfacial Surface-Active Macroinitiators for
Advanced new technologies for liquid crystals based on the hysteresis properties of cholesteric nematic transition were proposed.
Other work in organic chemistry involved synthesis of substances with polyreaction abilities for modifying surfaces or grafting different polymers to surfaces. The compatibility of chemical bonds with surfaces, such as for protective coating of optical fiber, is being investigated. Other work includes creation of components for a nematic colloidal system, water dispersion for films of special properties, special magnetic films for floppy disks, and dispersal methods for magnetic materials in magnetic information storage devices.
New Surface Active Substances for Generation of
Radical Processes on Interphase Boundary
New patentable technologies in monomers and adhesion problems for polymers led to contracts for patents and collaboration with several U.S.-based corporations, including Sherwin-Williams, Johnson and Johnson, and DuPont. The technologies involve new processes that are ecologically clean for the construction of films, composites, and lattices with interesting thermal and electronic properties.
Theoretical work was reported on the technology of semiconductor materials for sensing different physical parameters. The physical properties of polysilicons were being investigated relative to the employment of these materials as sensing elements. Other research involved the theoretical investigation of crystals for electronics. A new method in kinetic theory, which had potential for overcoming the problems of Boltzman's kinetic equation, was proposed to enable the prediction of the kinetic properties of crystals.
Materials of Special Purpose Based on the
Activated Polymeric Colloidal Systems (PCS)
The Radiotechnical Devices Department was doing work on improving the technology of the CRT. Work on super high resolution CRTs had developed an electron beam scanning spot of only 10-20 şm in diameter for use in the direct photorecording of information from the CRT. Various other technical improvements, both inside and outside the tube, were being worked on, that is, deflection coil improvement and use of amorphous metals and special composite dielectrics for reduction in distortion.
L'viv Polytechnica State University has achieved excellence in several areas that are of interest to the advancement of both LCDs and CRTs. The researchers have been successful in contracting patents and collaborating with U.S. corporations, such as DuPont, Johnson and Johnson, and Sherwin-Williams. Representatives of LPSU make offers for specific research collaboration in (1) Design and fabrication of ecologically clean polymeric compositional materials display technologies and semi- conductor materials; (2) Modelling and diagnosis of VSLI fabrication; and (3) Hybrid design of low-frequency circuits.
