Electroless Deposition of Composite Nickel-Phosphorous Coatings with Diamond Dispersoid

“…H. Petrov [17] has found that the rate of the deposition process at Т = 60-90 о С may reach up to 20-30 µm/h, which corresponds to the rate of electrochemical nickel plating. That is why in the present experiments for deposition of composite coatings with 5 g/l D 14/20 μm we have studied the influence of the temperature within the range 50 о С -85 о С.…”

“…According to H. Petrov [17], the hydrodynamic regime exerts significant influence on the thickness of chemically deposited composite coatings. In this connection, solutions with 5.0 g/l D 14/20 µm have been studied in the following deposition regimes: regime "а" -continuous air flow agitation; regime "b" -1 min air flow agitation, 1 min rest; regime "с" -2 min air flow agitation, 1 min rest; regime "d" -2 min air flow agitation, 2 min rest; regime "е" -2 min air flow agitation, 5 min rest; regime "f" -2 min air flow agitation, 10 min rest.…”

P3.5 - Impact of Dopants on the Characteristics of Thin-Film Humidity Sensor Elements

“…All of the procedures for preparation of products via the sol-gel method are based on the same sequence, represented by equations (1) and (2). In practice, there is a variety factors that predetermine the quality of the corresponding products [5]. As S E N S O R + T E S T C o n f e r e n c e s 2 0 1 1 S E N S O R P r o c e e d i n g s 7 3 8 with all other chemical technologies, the conditions for synthesis entirely predetermine the structure, and consequently, the properties of the respective product.…”

The place of health care in social services for people with disabilities

“…On the other hand, long-term healthcare services are regulated by the Law of Healthcare and the Hospitals Act (LHHA) and provided in different kinds of specialized medical institutions such as hospitals for further and continuous treatment, rehabilitation hospitals, long-term treatment and rehabilitation, state psychiatric hospitals and centers for mental health and hospices. medicine, healthcare and many other factors, favorable conditions are set up for the increase of not only the individual, but also the average life expectancy in all developed countries (3).…”

“…Different natural and social factors and conditions -material and cultural wealth, rational way of life, ecological environment, scientific advances of medical science and practical healthcare and others may have significant influence on the prolongation of human life, respectively on slowing the aging process (3).…”
