Why can't the Novosiolov and Geim's method of getting graphe (with an adhesive tape) be upscaled to manufacturing?
It is said "because this method is based on the handwork", but aren't we really able to do this, for example, with robotics as an iterative process?
I guess, there is a problem with...
I'm a final year (4th year) applied physics student studying in Ireland, and I've spoken with one of my professors about a possible PhD study. The study he offered me was to do with nanorods and their ability to kill/wave off bacteria, taking inspiration from the Lotus leaf. I've attached what...
Is there a problem of converting DC to AC in micro- or nano- scaled electric circuits? Is designing a new device that would perform such function in demand in micro- or nano- electronics?
I mean you could buy a mirror or silicon wafer but they give say 0.5 nm or 5nm 'roughness' which I suspect is the mean average roughness but this doesn't rule out a high "bump" way above the mean average such that for example 1 million bumps of 1 nm and just one of 5 will result in...
I know graphene particles are small but how do I work with them separately? If you tell me easy-to-accomplish way for handling a single grain of graphene at home...OK. I was thinking about something like a very thin sheet of graphene, but in quantum measurements they are huge: micrometers and I...
Hey everyone!
I'm really interested in nanosystems and currently collecting information on the topic. I've read quite a few publications and been on some webistes such as nanoplus (they explained what they do really well!) but I would also like to see what my think-alikes on here have to say...
Both the cz (Czochralski Process), and Float-zone refining of silicon require an inert atmosphere, usually argon. How pure does the argon atmosphere have to be? How high of a vacuum has to be pulled before releasing argon into the tank?
I’m using an inductive heater to try to melt some 99.85% polycrystalline silicon, as would occur in the Czochralski process, but the silicon workpiece is not melting let alone even getting hot. The silicon workpiece is about the size of a playing dice. It becomes conductive at 200 F and becomes...
Have a look at the article here.

Hi
My question is not long, but it is very broad; Is nanotechnology simpy just a rebranding of material science?
Is there anything else to it? I have not really seen it used outside chemistry and material science. Do simple nanomachinery exist?
I guess on a more speculative level it exists...
HI guys!
I was thinking...
What would happen if the atom were considered the smallest thing of the universe, or just that electrons, protons e neutrons were that?
That would impact in semiconductors technologies? Or plasma? Or nanotech? How?
Thanks in advance.
I am interested in pursuing a career in nanotechnology however i would like to know if i should do a B.TECH. Nanotechnology degree or something more specific like an undergraduate degree in electrical engineering, materials science, etc.
Please let me know which will be beneficial for my future...

i'm interested in studying nanotechnology at La trobe University and i want to know whether this is a good degree and whether i can do an engineering degree for my masters ?
The article on undecidability of presence of spectral gap by describing its microscopic structure seems to contradict the fact that we can decide whether a CNT is metallic or semi -conducting by checking its diameter and its twist.
I'm a first year student in college and I've started shadowing under a grad student, who's in a nano-optics research group (http://www.nanoscience.ucf.edu/chanda/), in order to learn about microfabrication. I'd like to start conducting my own research soon; however, i don't know exactly what it...
I do not know what to write here, so I just going to say hi! I am Aura a senior 2016 and in this point of my life the time has come to make in my opinion "the most decisive" decision of my life.
A figure in a recent paper from Science made me smile, so I thought I'd share it with you guys. The paper describes a new way of joining nanoscale building blocks together using DNA origami. It's based on the principle that if you have two DNA double helices with a gap in between (see the blue...
