How Can one cary out Electrolytic Nickel depositin on platinum?

I need to image mesoporous silica nanoparticles that are in ~100 nm size and do high resolution TEM to look at mesopores. what grids should I use?

Need to image mesoporous silica nanoparticles using the TEM. Also, need high resolution TEM images to see the mesoporous structure. Kindly suggest what kind of grids to use. Thanks, Shatadru

What is the state of the drug inside solid lipid nanoparticles (SLNs)?

I am a little confuse with the mechanism of solid lipid nanoparticles (SLNs). The main point of encapsulating drugs into SLNs is because some drugs have low solubility in water. Therefore, SLNs...

Which reagent is best among 'Dimethylglyoxime" and "Dithiothreitol" for spectroscopic determination of Nickel ?

What I think is Dithiothreitol. As it is water-soluble and does not form a precipitate. But, the thing is it contains sulphur which is quite hazardous to aquatic animals.

Dear Kirima Vacel

Read the following article, it may help you.

Zhao, Yue, et al. "A new route for the electrodeposition of platinum–nickel alloy nanoparticles on multi-walled carbon nanotubes." Electrochimica acta 52.19 (2007): 5873-5878.

Dear Kirima Vacel ,

I suggest using the so-called Watts-Bath:

300 g/L NiSO4*6H2O

45 g/L NiCl2*6H2O

45 g/L H3BO3

which has pH=4.5.

I have taken it from Navas, IEEE Trans. Magn. 42, 3057 (2006),

doi: 10.1109/TMAG.2006.880144 They deposited Ni onto a Au electrode at 35 ºC for 10 min with a current density of 1 mA/cm2, and they obtained a film with thickness about 200 nm.

Good luck!

watts bath is perfect and easy to coat, if you have bipolar rectifier then it will be fantastic. It will give you perfect coating with high bonding strength. You can vary the parameters to achieve good characteristics of the deposit
