Interaction between plasma sprayed YBaCuO and nimonic substrates

Superconducting and structural properties of plasma sprayed Y-Ba-Cu-O layers deposited on metallic substrates*

The properties of plasma sprayed Y-Ba-Cu-O coatings deposited on metallic substrates are studied. Stainless steel, nickel steels and pure nickel are used as substrate. Y-Ba-Cu-O deposited on stainless steel and nickel steel reacts with the substrate. This interaction can be suppressed by using an yttria-stabilized zirconia (YsZ) diffusion barrier. However, after heat treatment the Y-Ba-Cu-O lay...

Interaction between myosin and its substrates.

LOK concentrations of p-chloromercuribenzoate (PCMB), Zn++, or Cd++ increase the ATPase and CTPase activities of myosin B but inhibit ITPase and GTPase activities. Higher concentrations of these modifiers inhibit the activit,ics of all the IIIIcleoside triphosphat,es (NTP). Dialysis against cysteine ethyl ester (CEE) increases t,he ATPase and CTPase activit,ies of myosin but decreases the ITPas...

Interaction between intra-grain currents and transport current in bulk YBaCuO*

The hysteric magnetization curves of transport and grain currents are measured for a ring shaped sample by applying an a.c. magnetic field and using pickup coils. The dependence of the magnetization curves on the amplitude of the applied a.c. magnetic field can be explained by a simple model. This model takes into account the time dependence of the transport and the intra-grain current. We will...

Plasma-sprayed carbon nanotube reinforced hydroxyapatite coatings and their interaction with human osteoblasts in vitro.

Carbon nanotubes (CNT) possess excellent mechanical properties to play the role as reinforcement for imparting strength and toughness to brittle hydroxyapatite (HA) bioceramic coating. However, lack of processing technique to uniformly distribute multiwalled CNTs in HA coating and limited studies and sparse knowledge evincing toxicity of CNTs has kept researchers in dispute for long. In the cur...
