    I What are nanosystems and where can we find them in our daily lives?

    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...

    A Acceptable Atmosphere for CZ/Float-zone Refining

    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?

    A Silicon not heating with induction heater?

    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...

    Why is silicon not melting?

    I’m using a zvs 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, and becomes fully conductive after...

    Voltage on a quadrant photodiode used with an AFM

    Homework Statement An AFM uses a quadrant photo-diode to measure the deflection of the laser beam. Sketch the voltage in quadrants A, B, C and D as the tip travels on top of a single carbon nano-tube resting on a flat surface when the AFM is operating on tapping mode. Homework Equations Not...

    B What would happen if nothing was like it is

    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.

    A The spectral gap and it's decidability

    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.

    Studying Courses/Books Recommended for Metamaterial Research?

    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 (, in order to learn about microfabrication. I'd like to start conducting my own research soon; however, i don't know exactly what it...

    Making a Voltron out of DNA

    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...

    Engineering Relationship Mechanical Engineering and Nanotechnology

    I got a B.S. in Mechanical Engineering and I am now doing a PhD in Nanotechnology in which I am synthesizing a nanomaterial. Someone just told me that nanotechnology is more like mechanical engineering and materials engineering than any other thing. Based on my work I can see the relationship...

    Preparatory classes for nanotechnology

    I think having a career in nanotechnology might be the right choice. However, my school doesn't offer a concentration in nanotechnology unless you are in chemistry. I would like to know some undergraduate courses that would be helpful to me if I decided to go on to get a masters in nanotechnology.

    Superparamagents and superhot nanoparticle iron oxide

    I'm trying to understand superparamagentism. There is an experimental medical treatment that uses the superparamagnetism properties of nanoparticle-sized iron oxide particles. Injected into a cancer tumour, when the person is placed in a rapidly alternating magnetic field, the iron oxide...

    Surface plasmon dependence on surface area to volume ratio

    Hey everyone, I was recently reading a paper on surface enhanced Raman scattering, and it mentioned that plasmons (and for that matter surface plasmon polaritons-where my interest lies) are sensitive to the surface to volume ratio of the structure. I can begin to understand intuitively with...

    Cure for ebola?

    I was just wondering if some bacteria or nanotechnology could be genetically engineered to target the Ebola strains? Is this possible? If it is then why is no one coming up with a cure?

    Best route to go for Nano Technology (but still be able to get a job?)

    I want to go into nanotechnology but also keep my options open for employment purposes when I graduate. At the moment I'm Chemistry & Material Science double major and I thought that'd be a good combo however at the moment I'm thinking, would MatSci for a B.S be oddly too specific for a B.S...
