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.

I need help with my Nanotechnology VR multiplayer

Hello 😊 ,
My name is Mahran Abid, a final year master’s student in the DEDI program at the Higher Institute of Computer Science and Multimedia in Sfax. As part of my final year project, I am developing a Virtual Reality (VR) training application specifically tailored for nanotechnology.
This application aims to provide an immersive, interactive, and multiplayer training experience in the field of nanotechnology. In order to make this application as beneficial and user-friendly as possible, we have designed a survey to gather your valuable insights.
📄 We are interested in understanding your prior experience with VR and nanotechnology, your expectations from a VR training application in nanotechnology, and the specific features you would find most beneficial.
Your feedback will play a crucial role in shaping the features and functionalities of this application. Please note that all responses are anonymous and will be used exclusively for the development and improvement of this VR nanotechnology training application.
We greatly appreciate your time and valuable input. Thank you for helping us create a better VR training experience in the field of nanotechnology!
Looking forward to your responses.

Graphene at lower cost and higher quality.

I work for a company that sells graphene. Our process creates graphene directly from coal and not from graphite dependent on Chinese mines. That means our graphene is higher quality and far cheaper. Graphene adds 20% to 50% strength in most materials. If anyone has an interest, let me know.

Internship in physical engineering

Hi,

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?

Measurement of Ultra Low Currents in Nanotech

Hey,

I have a device where i can measure Ultra Low Currents accurately with a 6% error margin in the dynamic range of -6fA to 20uA. The issue is finding applicable technology where the measurement of these currents are essential. Any ideas?

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 ADVICE PLEASE

Hi!

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?
