Seeking Advice: Switching from Nano Engineering to Computer Science?

Hi fellow Nano Engineers,

I'm currently about to start my second year in Nano Engineering at Chulalongkorn University. I love the idea of Nano Engineering and am really interested in Neuralink, but I'm facing a few challenges and could use some advice:

  1. Struggling with Physics: No matter how hard I study, I just can't seem to get good at physics. It might be because I'm an ISTJ, and Nano Engineering requires a lot of physics? Has anyone else faced this issue, and how did you overcome it?
  2. Interest in Computer Science: Computer Science seems more practical with many open-source tools and online courses available. I like the idea of being able to build projects from scratch at home. Has anyone made a similar switch, and how did it work out for you?
  3. Lab Work in Nano Engineering: I've heard that the curriculum for Nano Engineering focuses on training students to work in the lab. Besides taking lab courses, I have no real experience. Should I contact professors to get some hands-on experience?

I'm contemplating changing my major to Computer Science, which I initially wanted to pursue. I think the CS curriculum and developer lifestyle suit me better. However, I'm also willing to sacrifice my undergrad years if it gives me a richer path in the future.

I'd really appreciate any advice or experiences you can share!

Thank you!

Currently e-ink is the most common technology that utilizes physical force on the micro level. Some parts of that could be used for finely controlled actuator array? Basically for mechanical tentacle for medical use

Electric fields pull and push colored charged particles up and down the e-ink screen thickness. One could imagine that magnetic particles in magnetic fields might also work. If some kind of actuator / electric motor is derived from that, it might be even simpler because no need for particles.

By the way, there is lots of room for improvement with e-ink and it could work with many different types of mechanisms. Also, if the parts are small enough they can affect color by using the wave property of light (related: Lippman plates, iridescence).

Chain of tiny electric actuators that are individually addressable by software to enable device's shape changes can have medical use

Firstly, if sensors are tiny and advanced enough, a whole array of such chains can be used in surgery, especially cancer surgery. The array could connect to usb port so that it is controlled with a laptop semi-automatically. Energy and data flows along wires during the surgery.

Secondly, if there is also a way to transmit energy wirelessly or a way to extract / generate electric power from blood's chemical energy, every actuator chain could separate from the controller device after receiving it's configuration file in binary form and continue to inside body autonomously. After that, some directions and/or navigation signals can be transmitted with magnetic field pulses or ultrasound. The insertion may be done in local anesthetic or maybe the device(s) can be injected to a vein upstream from the tumor or from something else that needs treatment.

It would be a tiny device that has even tinier integrated circuit in it, or is itself a tiny integrated circuit that is something other than a chip ( when looking at the definition of IC very carefully ).

It might use a drilling mechanism similar to this to first gain access to the tumor and then shred it:

(time code link)

It would probably be a MEMS device:

Range of possible sizes and lengths is large. Many very different sizes for different uses.

How to use spin coater for deposition of CdS and CdTe on ITO coated glass?

I am making a CdS/CdTe heterojunction photovoltaic, so CdS first and then CdTe. Has it been done before? If yes, can I get some references?
I have only seen papers using it for deposition of TiO2 and we aren't doing that. All the papers just ised CBD and only before that spin coating for TiO2. Also what binders to be used for it? Is PVA recommendable for it?

How to land a job in nanofabrication?

I'm a second-year electrical engineering student: I really love physics and I've enjoyed all my digital design classes. Secured an RF hardware engineering internship at a satellite company this summer.

I'm really interested in ASIC fabrication (and nanofabrication in general). Not too sure how to land a role in this space (or if it's even possible with just a bachelors, though I suspect it would be difficult). I'm assuming most of the jobs in this space would be at companies that actually do the fabrication (TSMC etc). What knowledge/skills/projects/activities should I be looking at doing/developing to set myself up for success in this space?

Also, this next part is only tangentially related but how often (if at all) in the ASIC design flow do designers take into consideration quantum and semiconductor physics and if so where in the design flow would those considerations occur?

Don't have much experience/knowledge in this space so I'd love some insight. Thanks in advance?

TLDR: How to land a job in nanofabrication?

AFM(Atomic Force Microscopy)??

Hi , If anyone here knows about AFM and would tell me the significance of steps for data analysing in AFM , I would really appreciate. I am a student and have been assigned a project based on AFM. Now when I do the tests , I am asked to do calibration of tip and rest of the stuff . I am also asked to check Pull of curves for adhesion etc . I just get average friction and set point from the device and am to convert them to friction forces in N. I Dont understand the significant of knowing various spring constants . Why do we calibrate lateral forces and why do we need pull off tests. What do these actually mean .

Any help would be helpful.

How do experimentalists obtain theoretical data?

I am interested in hearing how experimentalists in the field get theoretical data to support their experimental work? And what struggles do you experience in the process?

Lg 50nano75uqa slow loading data after power on

Lg channels take minimum 1 minutes to load? Also changing channels is slow , 5-20sec! Even toggling one channel up or down. Or previous channel toggling. Video quality and refresh is great once channel loads. This happens after several software, firmware updates. This happens when wired or wireless network connections. All other network are working properly speed. Not a local network issue.

[Open-Source] NanoRender: An Open-Source Python Package for 3D Modeling of Atomic Systems!

Hello there,

I've launched my first open-source project, NanoRender! 🌟 NanoRender is a Python package for generating 3D models of atomic systems (molecules, materials etc). The code generates a HTML file that showcases the model, which can be used independently or added to a website.

The code is literally in its infancy, barely a hundred lines long, but I am excited to see how it will grow as an open-source project.

Collaborations, contributions and comments are all welcome! Join me as we revolutionize scientific visualization with Nanorender. 🌍💻🔬

searching for good books

Hi, I am a freshman at The University of Warsaw, studying nanoengineering. I am very intrested in the subject and am seeking book recommendations to learn more about the subject, outside of my courses in Uni. Can anyone here recommend some? Thanks in advance!

I can't figure out the difference between nisome and liposome.

I am making a review about liposomes and I found out some papers about niosomes. Can I just ignore the different names and go ahead?
