ISSF STAINLESS STEEL IN MICRO HYDRO TURBINES- 9 Stainless steels in micro hydro turbines For all parts in contact with water, and particularly moving parts, corrosion resistance is essential. High water impact speeds customary in impulse turbines and high flow rates of Kaplan and Francis turbines require a good cavitation erosion resistance.

Stainless steel screws and other internal fixation devices are used routinely to stabilize bacteria-contaminated bone fractures from multiple injury mechanisms. In this preliminary study, we hypothesize that a chitosan coating either unloaded or loaded with an antibiotic, gentamicin, could lessen or prevent these devices from becoming an initial nidus for infection.
In order to ameliorate the properties of corrosion resistance and achieve applications in anti-biofouling of 316L stainless steel (SS), a sulfated derivative of chitosan was deposited onto stainless steel surface by an electrochemical method. In detail, chitosan-catechol (CS-CT) was synthesised in the hydrochloric acid solution by the Mannich reaction and then electrodeposited on the surface ...

The power generated by a hydro turbine is given in the following formula: P = Q*H*g*R in which: P: Power (kW) Q: Flow (m³/s) H: Head (m) g: a constant 9.81 m/s² R: efficiency ratio: about 80% or 0.8. ISSF STAINLESS STEEL IN MICRO HYDRO TURBINES- 5. Technologies.
01-06-2016· The production of metal and glass MNs using a manual process is not time efficient and clearly not feasible for industrial purposes. Unlike assembly of stainless steel wires, or needles, Martanto et al. used an alternative method. An infrared laser was used to fabricate arrays of MN shafts from 75 μm thick stainless steel sheets .
01-01-2017· Chitosan microparticles are formed by chelation of chitosan and metal ion, Cu, by emulsion coalescence to achieve enhanced controlled drug release due to the metal ion. The size of chitosan microparticles formed by chelation and emulsion coalescence was in the range of 20–30 μm.

The deproteination step is followed by a deacetylation step to remove the acetyl group from N-acetylglucosamine (chitin) to form an amine group, yielding d-glucosamine (chitosan). Each step is followed by a washing step and the product is dried, preferably at a temperature not in excess of about 65° C. Known purification and grinding steps may also be used to produce the final chitosan product.
