Nano Definition and 63 Threads

Researching the Casimir Effect and possibilities of incorporating this energy capture method into nano structures as part of any of diverse machines and systems, was linked here by an ai chat model. I wish to create entities. I am very interested in advancing our grids, states of the art...

How does one roughly predict the mean free path for electrical conduction in a nanostructure at different temperatures and under different electrical conditions such as different voltages and amperages based on the composition and dimensions of the structure? For instance in carbon single and...

Hi everyone, as a degree project to obtain a chemistry degree, i am developing the Synthesis of Fluorescent Gold Nanoclusters (AuNC). I have investigated the route to obtain nanoestructures of nanometric size less than five nanometers, reaction conditions, and so far i have managed to obtain a...

Can someone help me with the method for performing nano-coating on glass like substrate

Hi, this is my VERY FIRST post so if I've made a bundle of noob mistakes accept my pre-emptive mea culpa. I did read and like the rules. I have seen some stories in Phys.org about nano wires and I immediately thought of the nano wires in Larry Niven Known Space milieu which can cut right through...

Hi I am usually living off grid in simple huts in remote locations in Asia. A few months per year (rainy season) I don't have enough sun to produce solar power. I need very little electricity. My 20w solar panel produces enough electricity for my needs (lighting + charging a few small gadgets)...

I have a decent understanding of Nano and AMO physics, however when I started looking at colleges(applications started recently). I found out that the nano major is an interdisciplinary major or a specialization under either applied physics or electrical engineering. AMO is in some places its...

I'm needing to reflect additional solar into a greenhouse to increase plant beneficial PAR light (400-700nm) while restricting and minimizing excessive IR heat also building up inside, too. I'll be using 400 sq ft of flat plate reflectors (40'X10') at ground level horizontally positioned along...

I've been doing some work with my classes around the Yuri Milner Breakthrough Starshot project to send a tiny nano craft of mass around a few grams to alpha centauri. The starchip would travel at 20% of the speed of light. I've had them calculating various properties of the ship including...

2 types of nano spacecraft are planned to travel to Alpha Centauri , 4.2 light years away. One powered by an Earthbound laser, another self powered. I have loads of questions about this but here are a few - The report I read talked about an average speed of 25% of light speed. However, it is...

umm well that's about it

It's kind of strange to me that when reading topics like "components of cellphone screen", people often mention an outermost anti-reflecting coating which takes advantage of destructive interference. There're few mentions for using DLC-coating as a cellphone screen outermost coating but...

Hello, I would like to know that why carbon is used in nano technology to build nano tubes and other? Is there any other metal which is used to construct the devices of nano technology?

When experimenting with fusion, why do we always go so big and make extremely expensive reactors that take years to create and even construct facilities for? I've seen some failed attempts at making fusion happen in carbon nanotubes, failing in the sense that the carbon nanotubes are just...

Hello, In which way nano and solid state physics improve technology? where we use statistical physics more in nano physics or particle physics? where we use quantum mechanics more in nano physics or particle physics? which major is more enjoyable nano or particle physics? which major is more...

Hi! The other day, I read about Moore's Law. To me it seems a miracle how one could predict in 1965 that the number of transistors would double every two years. However, there has to be an end to this exponential growth due to limits of nano technology, fabrication of semiconductors...

We can find differential of alloy and composite. MMC is came from 2 differential of metal, one from it aren't melting same as producing alloy. but there are might produce new reaction. ex: C with Fe, the name is carbon steel. the nano-composite just too, but the particle aren't big, and the size...

Hello there, My name is Sara and I have an electrical engineering degree from an American university and a physics degree in the field of nanophysics from a United Kingdom university. I would like to move to the field of astronomy and astrophysics. I joined this forum to learn, share...

I am working on a project, however I am having trouble finding the right material for it to work. I am looking for a nano-material or any molecule that will emit a radio frequency when subjected to a voltage or a current at around 37 degrees Celsius. I would really appreciate it if someone could...

Hi there Is there anyone to help me about a definition of "DNA nano wire"?!

I am getting an opportunity to do PhD in semiconductor devices. The professor is quite active in the field and publishing good research. I have no background in solid state physics. How difficult it could be with a computer science background? Also where should I start once enrolled in a...

Dear all, I am preparing nano Cu particle by reaction of CuCl2 with NaBH4 in PVP solution. CuCl2 and PVP were mixed ultrasonically in pure water. Before dropping NaBH4 solution, the water was bubbled by N2 to remove O2. After dropping NaBH4, the solution turns into gold color. This means that...

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...

hello i need some help and am confuse about it now.. after calculating the math.. 1.67531519 x 10 power of negative 8.. if i change to nano it is 16nf? 1.515761363 x 10 power of negative 10, if i change to nano is 15nf? what about changing to miro? confuse with the 10 power of...

Hi everyone, long time lurker, first time poster. I've just begun a phd which involves nanoribbons (a small strip of a 2D material connected at either end to a larger 'bulk' section of the same 2D material). A question has occurred to me. These nanoribbons look a lot like a piece of string...

Hi every one . I am trying to make nanocomposite and I need to solve nano Tio2 in water many paper said that it will dissolve in water but I could not . I don not know what is the problem :cry:

I know what is lattice constant but it has been given that nano particles have reduced lattice constant due to huge fraction of atoms being in surface. How come the lattice constant of nano particles reduced due to high number of atoms present in surface? Why do the surface area, hardness...

Hi, I am preparing for a project based on nano physics, and I am just 'beginner'. While preparing I just could not make out the difference between nano physics and nanotechnology. Can somebody help me? Thank you very much.

Here is the abstract: http://pubs.acs.org/doi/abs/10.1021/nl304680w I would need to pay the $35 so I have not read the full text. Question: it says "...without Light, Heat, or Electricity." Where is the energy required to split the water molecules coming from? Jeff

Hey guys, I'm stuck in a rut. I'm currently in an engineering program--Nanotechnology, it's mostly focused on materials, chemistry, and electrical. In upper years there is an option to specialize in biology which is the original reason I wanted to attend this program. That specialization is...

I bought an ipod nano on ebay and the headphone jack is messed up. When I first got it, I was testing it, but it eventually wouldn't come back on, so I assumed it needed charging. I plugged it into the adapter on my computer that plugs into the ipod's headphone jack to charge it. I noticed it...

I'm interested in the theoretical minimum number, so like the extruded buckyball ball? I'm trying to work out if there are enough carbon atoms in a 'piece of paper' to reach the moon. :) Which brings me to the next question : how many carbon atoms are there in a piece of paper? Or...

Hi, I'm reading a paper (please find it here arXiv 1003.2193v1) on zigzag Graphene nanoribbon (ZGNR). It discusses the electron transmission through a p-n interface. The wave function matching method was employed to calculate the transmission. What I don't understand is as follows: In...

Nano-----, what means? What is a nanoblade? And a nanospring? I am not an expert about nanotechnology but I would like to understand something more. Thanks in advance.

what is nano? how to obtain nano material ?

I am a freshman at Wright State University in Ohio. I am trying to decide where to eventually place my focus at. I understand it is early but I am one of those people who puts in 20 hours of "fun" study time on the side while still doing my college work. To me Superconductors, Genetic...

is there any new technology use NANO engineering to create new generation of drugs ?

Fairly straightforward question: Why are nanoparticles generally made using metal, that too generally using gold, silver etc?

As I see it, there are two primary branches I can take to study and have a career in nanotechnology. There is the nanoengineering degree and the physics and mathematics degree. There are many merits on both sides namely: Nanoengineering: More employable without need of PhD Lack of of...

Not to long ago there was a lot of hubbub about nano plating and the low costs that comes with it. I was curious if anyone knows whether or not nano plating is commercially available yet or if its still in the research phase? I've got a lot of applications for gold and silver plating and would...

I have two questions: 1.) I am interested in nanoscience, specifically in the future development of nanobots and nanofactories. However, from what I've gathered from researching the field, this technology is apparently far off. Nanotechnology at the present seems to be focused on designing...

Is the only way to find a material's or compound's behavior at the nano scale through experiment or can we deduce its characteristics through some other way or theories?

Nano magnetite particles are found in the brain. They are associated with schizophrenia, parkinson's disease, aging and etc. Imagine that we are able to make a huge NMR machine and place a live human being in the bore to cause levitation. The diamagnetic particles will orient against the...

Hey guys, I'm researching single walled carbon nanotubes and I am trying to find out how much approx. Resistance there is in a pile of ~50nm long metallic SWCNT's piled on top of each other to form a line (think laying gunpowder for a fuse...). I'm perplexed because SWCNT's at the proper size...

Hi, I am doing a research project involving short single walled carbon nano tubes. Has research been done on the material properties of short SWCNT's that have been thermally bonded together? This is theoretically done by taking a few SWCNT's with each one overlapping the other (easiest...

Hi, I always had the idea that temperature is a thermodynamical property which means that the statical number of particles are important in measuring the relative temperature of the system. But, what happens when it comes to nano particles in which we have low numbers of atoms. How...

Apparently the nano laser is a key component necessary for practical application of optical computers. "Conventional lasers are limited in how small they can be made because this feedback component for photons, called an optical resonator, must be at least half the size of the wavelength of...

I slipped on ice and broke my wrist. Given our collective knowledge of the physics of slipping, isn't it possible that nano techology exists that allows us to add a non-slip substance to the soles of boots and shoes? Lev

Is it wise to go for an education in nano technology, or is it just a big hype? Nano technology is often divided into bio nanotechnology, nano electronics and nano material technology. Which one would you go for?
