Hi All!

Anyone need help with materials science topic, I can help you. I am Materials Science PhD, currently working in industry research. I am interested getting in teaching/tutoring again and love some opportunities to tutor who needs help.

Title?

I'm a second-year Metallurgy and Materials Engineering student. If you were in my position today, what would you focus on over the next two years to maximize your chances of getting a good internship or placement?

Hey reddit nerds,

Proud to say this is my first time posting on reddit. But seems this is the best place to turn for what I'm looking for... I am the founder of an early-stage computational materials and molecular design venture, and I’m looking for serious scientific talent to join my inner circle. I am not going to wave hands about generic "AI discovery." I have a functioning platform, and if you are the right fit, I will show you our pipeline, terminal transcripts, and data in our first call so you can see exactly what we've built.

What we have right now:

Active Physical Validation: We have a signed, funded Sponsored Research Agreement (SRA) with a top-tier academic biophysics/materials lab to ground our predictive engine in analog reality.

The Locked Panel: A 30-well experimental design plate of our deterministically engineered synthetic variants is undergoing various stress tests in a physical lab.

Complete Data Integrity: The entire pipeline runs on an immutable, content-addressed data provenance ledger mapped to strict data-integrity standards

We are transforming soft-matter engineering from an empirical guessing game into a Materials Design Automation (MDA) engine. We design custom, sequence-defined polymers and macromolecular architectures engineered to handle extreme environmental, thermodynamic, and non-equilibrium state transitions. We aren't blindly guessing molecular structures and praying. We built a Thermodynamic Constraint-Satisfaction Network that routes structural engineering based on specific target payload or system failure mechanics:

The "Matrix" Loop: For macromolecular systems vulnerable to structural dissociation under stress, our engine optimizes for precise charge asymmetry constraints ($\kappa > 0.40$) and specific Sequence Charge Decoration (SCD) topologies to form rigid, system-spanning physical networks that lock components in place

The "Shield" Loop: For components that fail via bimolecular aggregation or localized misfolding, the engine forces alternating topologies ($\kappa < 0.25$) to create highly repulsive, fluid steric spacers that maintain spatial stability.

This engine is already university backed and we have high aspirations for the impact it'll have on world health ( Will explain when we connect)

.

Who I need: I have the operational chassis and the physics engine moving. I need an elite team of scientists and engineers to help scale, refine, and push the circumference of this grid out. If you have deep, hands-on experience in:

• Inverse statistical mechanics & polymer/soft-matter physics
• Coarse-grained Molecular Dynamics (CG-MD) or enhanced sampling simulation
• Generative biomolecular/polymer design codebases (Diffusion models, ESM-family, structural inference networks, etc.)
• Physical chemistry, glassy state dynamics, or ionic transport (with an eye for broad materials engineering, from macromolecular stabilizers to solid polymer electrolytes)

Who I'll Take: honestly, if you are highly fluent in claude code, the science is just a plus. I need hustlers who are fluent in claude code. We can teach you the science (tbh many tasks you don't need to even get it).

This venture took off much sooner than i anticipated and i have a mandate to assemble a 15 person team within the next 3 weeks. If you want to be on that team, dm me here with a brief bio and/or CV and include the # of hours per week you can dedicate to this. Comp can be paid in all forms, though most of our recent hires are taking option packages so we can use all fundraising proceeds for compute and commercialization.

thanks!

Hi there! Quick background: I did a bachelor's in chemistry (north america) and I'm starting my MSc in Materials Science and Engineering (2 years duration - europe) this fall. Everything I've done so far has been academic research (2 projects- not related to materials), no actual industry experience in materials. I'm based in Europe (French nationality) but my end goal is working in the North American market eventually.

I'm trying to land a materials-related internship for next summer (and eventually a job after graduation) and I'm not sure how to compete with people who already have industry internships under their belt. My CV has experiences that shows clear communication and people skills, but nothing that reads as real technical or industry experience in materials. I'm worried a hiring manager sees no industry exposure and assumes I won't function well in a company, even if though I would say my science skills are pretty solid.

my questions are: how do I actually show my worth on a CV and in interviews when I don't have that experience to point to? What can I do beyond just saying I'm motivated, is there something concrete that actually lands with a hiring manager? Does research experience count if framed right, or do recruiters just discount it? Also, is it worth applying to big companies or should i focus on smaller ones?

Thanks for your help and would be happy to receive any advice :)

Hey r/Semiconductors,

Over the past few years, I’ve noticed a gap in structured, practical resources detailing the complex world of etching gases C4F6，CF4，HCl, Cryogenic etch...and their specific behaviors in RIE/ICP systems.

To bridge this gap, I’ve compiled my industry experience into a book that is now officially available on Amazon. It covers:

• Detailed chemical properties and reaction mechanisms of core etching gases.
• Process optimization strategies for different substrates (Silicon, Dioxide, Nitride).
• Crucial safety protocols, abatement methods, and gas delivery system design.

Whether you are a process engineer, a student entering the fab, or working in facility safety, this guide is built to be a practical reference.

Check it out on Amazon if you're interested! (Search for [Etching Gases in Semiconductor)

Would love to hear any feedback or answer any questions here.

Hi Everyone, we manufacture printed metal cans (for paints, thinners, general cans, etc.).

We are currently filling out a REACH / SVHC compliance declaration form for a customer. Our liquid formulations—specifically a White Base Coating and a Clear Varnish—contain Butyl Carbitol (CAS 112-34-5, around 5-20%) and Toluene (CAS 108-88-3, around 1-10%) as carrier solvents.

According to REACH Annex XVII, Butyl Carbitol is heavily restricted specifically for spray paints/aerosols. Our product is a standard liquid industrial coating applied via rollers, and the solvents are supposed to evaporate 100% during the thermal oven curing/drying process. Technically, the final finished good (the dried, cured metal sheet) should contain 0% active liquid solvent.

To satisfy our customer's auditors and prove that these solvents have completely volatilized, we want to send the fully cured/dried metal sheet samples to a 3rd party commercial lab for a quantitative test. Our goal is to get a "Not Detected" (ND) report.

However, local commercial labs are turning us down because this specific service isn't in their standard routine catalog. One international lab asked us to provide the specific standard testing method/protocol so their method validation team can check if their GC-MS setup can handle it.

My questions for the analytical/coating chemists here:

1. What is the standard international test method (ASTM, ISO, EPA, etc.) for analyzing residual volatile organic solvents trapped inside a fully cured/dry paint film?
2. How is the sample preparation usually done for this kind of matrix? Should it be a solvent extraction after scraping the dry film, or is there a better headspace/pyrolysis GC-MS setup commonly used for this?

Any insights, documentation references, or advice from anyone who has dealt with REACH compliance for cured coatings would be highly appreciated!

Title. For undergrad. I feel like there would be more opportunities at Northwestern since it’s much smaller? I’m deciding on which college to ED to!

My boyfriend has been applying for the scientific editor role in renowned journals such as Elsevier, Wiley, Springer. Despite being from a similar background as mentioned in the job requirements he has not received any response till date. He has no idea whether he has been rejected or accepted on what basis. He wants to start his career in a scientific editor role and has done a PhD from Europe in optoelectronics. He has applied multiple times. On tracking on the Springer website it has been showing under review for almost a month now. As he is new in the job market and I being from a completely different background we are unable to understand where and what goes wrong in his application. If anyone has any idea or is into such roles then please let me know how he should tailor his CV so that the prospects of interview call increases. I'll convey the same to him. It feels so sad that he puts in a lot of effort for a single role with no update.

Want to know if the job market in this field is good , like is it easier or difficult to get a job in this compared to IT, ELECTRICAL etc

I am applying for material science undergrad this year. I would like to know whether learning python is still worth the time and effort given that we are coming to learn of increasingly intelligent vibecoding platforms. Additionally, I feel like it is fairly easy to get to know the basics of coding but it takes a lot of time to get properly fluent in python. Lmk your thoughts

I am a male and currently work in a lab as a lab technician at 21 years old. I work in an epoxy formulations lab and the stuff here that we do looks pretty cool to me. I’m looking into different fields to get into and materials science is one mainly because I like the work and study that goes into it.

I’m asking for opinions and experiences in this field to see if i should pursue a career in this field. I wanna know what tuition looks like, the process of learning, what goes into it, the stress, the workload, Everything I really want to know everything. There’s some schools here in colorado that offer materials science classes so I’m really interested. Chemistry is also there in the back of my mind. So please if you have any ideas, comments or suggestions on this please say so.

Hey,

I am getting the above mentioned branch in uoh through csab. And i had some doubts about it.

1)How is the college environment( I've heard it's pretty good)

2. How are the hostels and mess( also let me know their fees)

3. I am actually thinking of partially dropping. So how hard is it to leave college after the first year(ie is there any problems that i may have to face or do you know smn who did the same?)

4. What is the scope in this branch? What roles and packages can i expect?

5. How lenient are the professors and overall academics? Will i get free time?

It would be really helpful if one of the seniors could answer this. Thank You🙏🏼

I am planning to do material science from iit and then do ms in foreign ( europe or north america ) , just want to know how are the jobs is it easy to get , if possible I want to know about salary and is the job market tighter than IT and is it worth it to go in this path , like I just want to settle in foreign and I heard that the IT market is tight right now

Sorry if this isn’t the correct group, but does anyone know if there is a standard gold thickness for components that have NiPdAu finishes? I am having a debate with a coworker on when gold embrittlement is a concern with gold thickness, and when gold washing is required for SMT parts per industry standards for aerospace product. I found a TI forum that suggested anything over .70 micro inches of gold should have tinning required but my coworker disagrees and said it has to do with the gold to palladium ratio. Note, I only barely understand the basics of this application as I’m about 2 months into the job, but I can find very little online about this

I am applying to colleges soon and would like to major in Material Science engineering but it seems that most schools I look up only offer a Masters or PHD in this field. Could anyone list or recommend some programs?

I have been looking out at Pls and research groups who work in the above fields. Till now UC Santa Barbara & Berkeley seems to be the best with many profs working in the field. Any idea which other unis to look out for? Please suggest.
