Superconducting MgB2 thick film has been prepared via hybrid physical-chemical vapor deposition method on Al2O3 (0001) substrate by using B2H6 and magnesium ingot as raw materials reacted from 730 to 830°C for 40 min under 20 to 30 kPa.
      
We fabricated several superconducting MgB2 thick films on stainless steel (SS) substrates by using hybrid physical-chemical vapor deposition (HPCVD) technique.
      
Thick MgB2 (magnesium diborate) films, ~10 μm, with Tc (onset) = 39.4 K and Tc (zero) = 39.2 K have been successfully grown on a stainless steel substrate using a technique called hybrid physical-chemical deposition (HPCVD).
      
A physical-and-mathematical model of the motion of a plasma cluster to a target is suggested.
      
A physical-and-mathematical formulation is given of the problem on the interaction between two opposing (incident and reflected) flows of plasma formed upon collision of a plasma cluster with a target.
      
Author's abstract of a dissertation in competition for the scientific degree of Doctor of Physical-Mathematical Sciences.
      
Statulyavichus, Doctor of Physical-Mathematical Sciences.
      
Author's abstract of the dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Physical-Mathematical Sciences.
      
Gnedenko, and Doctor of Physical-Mathematical Sciences Professor F.
      
Physical-Chemical Properties, Physiological Activity, and Usage of Alginates, the Polysaccharides of Brown Algae
      
Their raw sources, chemical structure, and physical-chemical properties are discussed briefly.
      
Relation of Physical-Mechanical Properties to the Structural Condition of Severely Deformed Patented Carbon Steels at Drawing
      
It is emphasized that the formation of the fresh groundwater natural resources within the hydrogeological massifs is governed not only by the physical-geographical conditions, but by the geological-structural factors as well.
      
The combination of these factors and the significance of each factor are not constant but considerably vary in space, depending on the physical-geographical, geological, and hydrogeological conditions.
      
Unlike other hydrogen-bonded crystals, the crystals of this class are characterized by delocalized hydrogen bonds producing considerable influence on their physical and physical-chemical properties.
      
A comparative analysis has been carried out of the physical-chemical state of the surface and bulk of single-crystal films of the iron garnet Y2.6Sm0.4Fe3.7Ga1.3O12 on substrates consisting of a gadolinium-gallium garnet single crystal.
      
Structure and physical-mechanical properties of nanostructured thin films
      
It is believed that materials based on ultrafine (nanoscale) diamond powders can possess high-level physical-mechanical and performance parameters characteristic of a nanocrystalline state.
      
Physical-mechanical properties of nanocrystalline materials based on ultrafine-dispersed diamonds
      
The physical-mechanical properties of polycrystals produced on the basis of ultrafine-dispersed diamonds (UDDs) at high static pressures with the use of thermal treatment in vacuum are investigated.
