For your prepared Cu nanoparticles in DI water, my suggestion is that you first get sure that they are in the mettalic form. As Cu nanoparticles are very much prone to oxidation giving copper oxide.
Second, you can go for lyophilization,…"
"it may be the process you adopted for the synthesis giving you the morphology what you probably seeing in TEM. Did you did SEM?
If you have doubt using ethanol use DI water then but it will take a bit long to dry so place the grid between two glass…"
"Hi the problem is not with the solvent.
1. disperse your samples in ethanol
2. Sonicate for few seconds
3. let big particles settle down for few seconds
4. Hold the grid using a twizer in air
5. pick a drop from the upper portion of the solvent…"
your diagram design for nanouniversity and nanocity present idea for the relation between nanouniversity and nanocity and the nanouniversity as the centre of important elements of nanocity
the project acceptable for discussion
The invertion of 10G optical transceiver has greatly increase the networking speed, for the science behind the transceiver, please check website and learn about CWDM SFP transceiver, www.fiberoptictransceiver.net
The XFP (10 Gigabit Small Form Factor Pluggable) is a standard for transceivers for high-speed computer network and telecommunication links that use optical fiber.please visit www.xfptransceiver.com for more info
