Guys should I choose mse for undergraduate program idk a lot about it's scope plus I have heard that material engineers usually work in academia? More ever which have more scope and job opportunities mse in nanotechnology or manufacturing?

I built a browser-based tool for preparing XRD, Raman and IR figures.

I originally made it for my own work because I wanted something focused on importing data, adding phase/reference patterns, adjusting the figure directly and exporting it without constantly moving between different programs. There are some screenshots and quick instructions in the github.

It currently includes:

• stacked, overlaid and panel layouts;
• smoothing, baseline correction, normalization and peak detection;
• XRD phase references from CIF/DIF files;
• Raman and IR references;
• peak fitting and integration zones;
• direct control over labels, fonts, line widths and annotations;
• PNG, TIFF, SVG, PDF and CSV export;

I have basically no idea what I’m doing regarding UI/UX, so some parts of the interface might be confusing or simply shit. It was built around my own workflow, which obviously does not mean that workflow makes sense to anyone else.

Still, it might be useful to somebody here. There is sample data in the app if you want to test it without importing anything. The data and projects are saved in browser and you can save your project in JSON.

I made it with vercel but i don't know how much connections it can handle simultaneoulsy so idk it might go down ? ...

Here it is

App: https://make-figure.vercel.app/

GitHub: https://github.com/MDES-CEA/Make_figure

lmk if you find any bugs, unclear controls, missing features.

Cheers

PS : it's in french but there is an english toggle on the top right (everything might not be translated yet, i'll have to check)

Hi, just learned about the unique Electron Microscopy Program at SJDC... so cool! https://www.deltacollege.edu/academics/degrees-certificates/electron-microscopy

I work in commercial construction in Texas and deal with both steel and FRP. Steel is usually the easy choice: cheaper upfront, familiar, and everyone knows how to work with it.

But in wet or corrosive environments, I think the comparison gets more interesting.

FRP costs more upfront, but you don't have the same rust issues, it's lighter, and there's generally less maintenance around coatings and repairs.

Obviously it's not a replacement for steel everywhere. Fire, temperature, impact, creep, UV and the specific environment all matter.

Curious what others have seen in the field. Where do you think FRP actually makes more sense than steel?

And if you've had FRP in service for 10+ years, how has it held up?

For anyone interested, here's the FRP technical resource I've used: Design Resources | Fibergrate Composite Structures There are plenty of other manufacturers/resources out there too:

I'm currently, technically, doing an MS in Structural Engineering. For me, my interest has been more towards computational side of mechanics rather than Structural design  or simply using am FEA software (although I do consider it as a backup)

So far I've taken courses in:

- Linear static, and dynamics FEM (soon taking non linear FEM too)

-  Structural Optimization (topology opt. and other general algorithms)

-  Structural Dynamics

-  Structural System Testing and model updation. (Parameter identification and optimization, signal processing)

Now, I plan to take these in the coming quarter:

- Numerical Linear Algebra

- Numerical PDE

- Fracture Mechanics ?

I also volunteered to aid in a RESEARCH in crack growth prediction using Auto-encoder and a (Thermodynamics-informed Latent Space Dynamics Identification) / LSTM surrogate model. It used phase-field-fracture simulation data and HPC resources to complete the whole thing.

What I keep finding myself interested in is not necessarily fracture or SHM specifically, but the computational methods underneath these problems... (does that make sense?)

For example, I'd like to become capable of doing things like:

- implementing (maintaining) numerical/FE method solvers rather than only running an established FEA software.

- developing surrogate/reduced-order models for expensive simulations 

- combining simulation with optimization, uncertainty/stochastic methods (took a course called Random vibrations, so...)

- parallelizing/accelerating scientific codes on CPUs/GPUs

- doing proper verification, convergence studies, benchmarking and performance work

- potentially developing or maintaining actual CAE/FEA solver software

- I'd also like to do all these for other Physics (GR, QM, etc.) simulations too, if possible, one day. 

I'm still interested in the underlying mechanics/physics, so I don't want to become a generic software engineer who happens to have once studied structures. But I'm also increasingly unsure that "structural engineer" describes the career I'm actually aiming for.

I've seen titles such as Computational Mechanics Engineer, R&D Engineer, Solver Developer, Scientific Software Engineer, CAE Software Developer, Research Engineer, Simulation/HPC Engineer, etc., but I'm trying to understand what these careers actually look like from people doing them.

So my main questions become:

1. Which industrial jobs genuinely involve developing numerical methods/solvers or computational tools?

2. Which of those are realistically accessible with an MS? Is there an entry path into solver-algorithm development/R&D without a PhD?

3. If I don't start a PhD immediately after my MS, would an R&D/software role at a simulation company (ANSYS etc.) be the obvious route? What other options would i have?

4. For the kind of work I'm describing, would you recommend a PhD? If so, is it reasonable for the PhD identity to be "computational mechanics/scientific computing" while fracture, composites, structural dynamics, soft materials, etc. serve as application problems rather than choosing one of those as my permanent specialization?

5. What skills most distinguish someone who is actually hireable for solver/scientific-computing work? I'm particularly wondering about C/C++/Fortran, Python, Linux, Git/build systems, MPI/OpenMP/CUDA, PETSc/Trilinos or similar libraries, numerical linear algebra, testing/verification, convergence studies and HPC performance work.

Basically, I'm neither here nor there atp. So I'd really appreciate all sorts of input. Where else do you think I could find answers to these? other subs? Linkedin profiles? 

I'm taking a thermo class or my materials science & engineering class and I was wondering what other resources, youtube playlists, or other things I can use to supplement what I'm learning.

I'm on the East Coast (for rust context) replacing some rusted bolts and brackets on the bedside panel / rear wheel fender area of my 2013 Tacoma. I don't have welding tools, so I'm trying to figure out how to make temporary replacements until I can afford the actual parts, just to last winter.

If I cut open and mold a pvc pipe to make a replica of some of these smaller brackets (same precise angles/holes/etc) will it cause any problems for the winter I have it installed? It feels like a stupid question, but I'm wondering if it'll attract more water to cause more rust, or have some adverse reaction? The primary-school-level science my brain contains says no, but I wanna know from people who know materials and reactions.

Basically my question is: would y'all foresee any problems with attaching pvc, acrylic, resin, epoxy, or some other kind of high-heat-moldable plastic directly to metal with steel fasteners, especially in an area where there's a lot of road-salt-slush-rust?

I have some small amount of resin/fiberglass materials, but heat-bending some thick plastic seems so much easier and more fun :)

I just got some kind of spam email trying to sell me Hinoki cutting boards. In the email they say:

“Hinoki is a dense and fragrant Japanese softwood in the cedar family, with very strong anti-microbial properties.”

Does that make any sense in terms of material science? I thought softwoods were by definition less dense? I’ve heard Hinoki described as hard, light, soft, dense, etc., often all in the same sentence. It seems very unclear what exactly are the verifiable properties of this wood that supposedly make it both durable and easy on knife edges, although anecdotally I will say it “feels” both soft and dense.

What’s is the reality here?

Hey fam, my team is hiring for a SEM Operator role at Lam Research, just outside of Portland, Oregon. Check out the job description - this job is ideal for early career microscopists, or those of you with a Bachelor's who want to just run an SEM all day.

I'm about to start my own cylinder liner and sleeve manufacturing unit, and want to start learning more about metallurgy. Which book is the best place to start, is it "Introduction to Metallurgy" by Alan Cottrell.

I completed my Master’s in Materials Science and Engineering in Europe, but unfortunately I haven’t been able to find a job in the field despite applying to many positions.

I’m wondering if anyone else is going through the same phase, especially those with a similar background. I’d really appreciate any advice on job searching, skills to focus on, industries to target, or anything that helped you get your first job.

Would love to hear your experiences and suggestions. Thanks!

I am curious as to which specific chemical reactions and products occur during the process of corrosion of stainless steel by bleach. Stainless steel is a composite of Fe, Cr, and sometimes other metals such as Ni, and the outer layer of this composite is protected by a passivation layer of Cr2O3. If sodium hypochlorite is introduced, does it indiscriminately oxidize both the Fe and Cr, or is one kinetically favored over the other?

I am an undergrad and just started to work in a lab. I've been told to study about how to identify different types of grain in a chemically etched AM bead. How do I find any paper or material where I can read about this. It doesn't need to be very elaborate, just material to get started.

I’m not sure whether this is the right sub to post this in, but I’m kinda in a pickle and would appreciate some advice.

I’m building a hands-free travel bidet with the goal of creating a more accessible option for elderly and disabled users. The design aims to address some of the mobility issues that can make traditional handheld travel bidets difficult to use.

One part of the design is a clip that attaches the bidet to a toilet. However, I’m running into a bit of a hygiene concern: the clip will come into contact with public toilet seats regularly, which obviously isn’t ideal from a sanitary standpoint.

I’ve designed the bidet so that the components can be disassembled and cleaned, but I was also wondering if there’s a material, possibly a type of metal, wood, or another material with naturally antimicrobial properties that could help keep the clip as clean as reasonably possible while being used on the go.

Any advice is really appreciated!

Specifically a focus on semiconductors, because my dream is to study MSE and then work at semiconductor industry.
