AI Thread Summary
Nanoshells are nanoparticles composed of a dielectric core, typically silica, surrounded by a metallic shell, usually gold. Their unique optical properties allow them to be tuned to absorb or scatter specific wavelengths of light by adjusting the core's diameter and the shell's thickness. For research on nanoshell construction, it's suggested to utilize scientific search engines like Scirus or access Chemical Abstracts for comprehensive historical data. General online searches may yield limited results, emphasizing the importance of specialized resources for in-depth information on nanoshells and their applications in medical science.

I can't seem to find much information on the construction of nanoshells. If anyone can post a link or briefly explain how nanoshells are generally created in a lab today, I would be very thankful.

I'm supposed to write a paper on nanoshells and their impact on medical science. So any further help will be appreciated.

Nanoshell

Hello,

I have found the following at this website:

Nanoshells are nanoparticles with a unique property — they can be optically tuned to either absorb or scatter particular wavelengths of light. Nanoshells are created from a dielectric core (like silica) and an outer shell of gold or another metal. By varying the diameter of the core and the thickness of the metal shell, Nanoshells can be crafted to reflect or absorb different wavelengths.

Hope this helps, remember that googling with the word "nanoshell" gives useful info.
 
I googled for 3 hours before posting this thread :)

Thanks for the link and advice anyway, though the link didn't provide much information regarding the construction of nanoshells.
 
Hey! extremely interesting subject! Congratulations

I can´t help you, but I encourage you to continue working on it. Good Luck
 
You are right about not finding many useful links on google, Xenorelic. Maybe switching to more scientific search engines like Scirus or using the powerful connection options of your local library's scientific subcriptions, more tempting results are likely to be achieved. I strongly suggest that you search Chemical Abstracts for at least 2004-1998 period, available on CD-ROMs in many instutions. It contains information maybe never obtained elsewhere but a little abstract.
Regards
 
Scirus is great. Thanks.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
