The Nanotech Reddit

Nanotechnology (sometimes shortened to "nanotech") - the manipulation of matter on an atomic and molecular scale. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size.

Nanotechnology as defined by size is naturally very broad, including fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc. The associated research and applications are equally diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale.

Scientists currently debate the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted.

need help for assignment

hello, it is near the end of the semester and our teacher gave us a "fun" ( still counts for marks) presentation assignment where we have to choose a item/thing from a movie, my and partner chose nanobots from the Avengers and we have having a bit of trouble. So, i came here to ask you guys. How would our society be impacted if nanorobots as advanced as Tony starks existed impact / revolutionize the world?

Internship in physical engineering


I am a 3rd-year bachelor's degree student in Physical Engineering, and I have chosen to do an internship in the last semester of my bachelor's. Here in Turin, we have the National Metrological Institute that offers the possibility to work for them.

Now, the problem is that there are several different topics that they study, and I can be interested in.

  1. Quantum Photonic: Quantum Key distribution, Quantum Zeno effect, and quantum sensing with diamond nitrogen-vacancy.
  2. Spintronics and nano-magnetism
  3. Quantum Electronic: Quantum Hall-effect and Superconductivity.

I don't know what to choose because I don't know what I will do in the future, and I just want to learn. I would like to hear your opinion about it.

What degree should I pursue?

Anyone working in biotech or nanotech, please help!!

I'm quite drawn to the health, pharmaceutical, food, ecological or even material production industries. I liked the idea of participating in the scientific process that are involved in each of those. More specifically, in applying biotechnology or nanotechnology in any of the industries I mentioned, after having finished a degree and specializing on either of those two.

What degree might be suitable for what I have in mind?

Or anyone who works in biotechnology or nanotechnology, what did you study to get there?

A Speculative Proposal For Atmospheric Carbon Capture

If feasible, the scientific and engineering communities should undertake an effort to create an environmentally friendly, self-sustaining, low cost means of atmospheric carbon capture. We propose the creation of a self-replicating atmospheric carbon capture device (RACC) - either an engineered bacteria or an analogue derived from available synthetic biology toolkits. The RACC should:

  • Be free floating in the atmosphere
  • Use common elements found within the atmosphere for self-replication
  • Utilize available solar and/or chemical energy
  • Capture atmospheric carbon and bond it into small flakes heavy enough to precipitate back to the Earth's surface

Deployment of the RACC can be carried out either via balloon or airplane.

Such a proposal raises substantial environmental and safety concerns that warrant careful consideration. To that end we propose the following design requirements -

  • Rigorous controls should be implemented to govern the self-replication phases of the RACC, mitigating the risk of unrestrained proliferation.
  • The RACC's operation should be confined between altitudes of 600 and 13,500 meters
  • All RACC devices should deactivate and safely break down once atmospheric carbon levels fall below 350 ppm
  • The resulting precipitate flakes should be too large for humans and animals to inhale
  • The RACC should become inert and break down safely if ingested by any plant or animal

This speculative proposal, while technically ambitious, could significantly mitigate climate change effects. This undertaking should be approached with great care, adhering to the highest standards of environmental safety and scientific responsibility. If a RACC under 10 microns can be engineered to meet these design requirements, it should be done as quickly and as safely possible.

Career in Nanotech

Can a degree in Mechanical engineering with a minor in biochemistry get my foot in the door of a nanotech company?

02:36 UTC




I am currently a student of Biotechnology in my local university (UACJ, in Ciudad Juarez Mexico).

I am seriously thinking about studying another career when finishing this one, I am thinking of studying bachelor in nanotechnology.

How much opportunities would I get having:

-Bachelor in Biotechnology.

-Bachelor in Nanotechnology.

And also a Masters degree in a nanotech related field.

Apart from being passionate about those two areas, would having those two degrees give me an advantage above people with just Bachelor in Biotech?

/r/nanotech will go dark on June 12th in protest of Reddit's API changes that will kill 3rd party apps

Adapted from: r/Save3rdPartyApps post here.

What's going on?

A recent Reddit policy change threatens to kill many beloved third-party mobile apps, making a great many quality-of-life features and accessibility functions not seen in the official mobile app permanently inaccessible to users.

On May 31, 2023, Reddit announced they were raising the price to make calls to their API from being free to a level that will kill every third party app on Reddit, from Apollo to Reddit is Fun to Narwhal to BaconReader.

Even if you're not a mobile user and don't use any of those apps, this is a step toward killing other ways of customizing Reddit, such as Reddit Enhancement Suite or the use of the old.reddit.com desktop interface.

This isn't only a problem on the user level: many subreddit moderators depend on tools only available outside the official app to keep their communities on-topic and spam-free.

What's the plan?

On June 12th, many subreddits will be going dark to protest this policy. Some will return after 48 hours: others will go away permanently unless the issue is adequately addressed, since many moderators aren't able to put in the work they do with the poor tools available through the official app. This isn't something any of us do lightly: we do what we do because we love Reddit, and we truly believe this change will make it impossible to keep doing what we love.

The two-day blackout isn't the goal, and it isn't the end. Should things reach the 14th with no sign of Reddit choosing to fix what they've broken, we'll use the community and buzz we've built between then and now as a tool for further action.

What can you do?

  1. Complain. Message the mods of r/reddit.com, who are the admins of the site: message /u/reddit: submit a support request: comment in relevant threads on r/reddit, such as this one, leave a negative review on their official iOS or Android app- and sign your username in support to this post.
  2. Spread the word. Rabble-rouse on related subreddits. Meme it up, make it spicy. Bitch about it to your cat. Suggest anyone you know who moderates a subreddit join us at our sister sub at r/ModCoord - but please don't pester mods you don't know by simply spamming their modmail.
  3. Boycott and spread the word...to Reddit's competition! Stay off Reddit entirely on June 12th through the 13th- instead, take to your favorite non-Reddit platform of choice and make some noise in support!
  4. Don't be a jerk. As upsetting this may be, threats, profanity and vandalism will be worse than useless in getting people on our side. Please make every effort to be as restrained, polite, reasonable and law-abiding as possible. This includes not harassing moderators of subreddits who have chosen not to take part: no one likes a missionary, a used-car salesman, or a flame warrior.
