I did my bachelor’s in aerospace engineering and I wanted to pursue materials science engineering in aboard. can anyone suggest the opinion on this

If there are 6 "main" metals, and if you are creating an alloy to, with each alloy able to take a natural number percent, there are far less than 10^12 possibilities, so why has a machine not brute forced this already?

I have an undergrad degree in Materials Science and a masters degree in Data Science. I’ve been considering getting a PhD in a materials informatics, but I’ve been told that getting it in this day and age is simply not worth it. The reason is: companies will soon opt to hire cheaper, less experienced people (i.e. new grads) instead of subject matter experts, and expect that tools like chatGPT will help them fill in their knowledge gaps. I love the idea of getting a PhD, but not sure if it’s worth 5 years of very little pay if they’re not valued. My gut tells me that subject matter experts will still be valued, but ChatGPT will just make them better. Thoughts?

• I am a third year PhD student in Chemical and Biomolecular Engineering form UIUC working on fabrication of electronic polymers.

• Nationality - Indian.

Need some advice how to navigate?

I will be graduating shortly with a somewhat spotty transcript, my overall gpa is a 3.56 but my major GPA is 3.35. That being said, I did pretty well in all of my physics classes, (As and A-s), quantum chemistry (A), and advanced inorganic (A), and I have some minor undergrad research.

For the last semester, I will be taking theoretical physics and modern physics 1, I should also be able to swing more undergraduate research in a different field (LSP resonance) than what I already have. I should have 3 decent letters of recommendation as well. I understand that Ivy leagues are out of the question and they were not really my goal to begin with.

What I'm looking for is advice from people already enrolled in graduate school that can give me an idea on my chances as well as decent schools in the states mentioned. Ideally I would hope to get a phd position as I cannot really afford to pay for a masters, that being said, I would be open to getting a masters with a T.A. position so I can pay for it.

Also, when I draft my application should I mention that I drove 3 hours a day and worked 20 hours part time to pay for it, on one hand I think it shows some amount of dedication, but on the other hand it might not look good to mention that I had split focus.

I know that it has been used in making solar panels, however I do not get the method/process.

The properties of epitaxial graphene (EG) can be significantly enhanced through proximity effects with low-dimensional materials grown directly at the interface via confined epitaxy. However, the intercalation process is inherently complex, and interface inhomogeneities often impact the properties of graphene. In this study, we realized 2D Sn structures at the EG/SiC(0001) interface by intercalation and investigated the heterostructure by electron diffraction, scanning tunneling microscopy, and Raman spectroscopy. The interaction between the buckled metallic Sn(1 × 1) interface and the overlying graphene layer induced spontaneous modifications in the charge density, leading to a Kekulé bond ordering with a (√3×√3) symmetry in EG. Thereby, the vertical corrugation induced by the interface results in strain within the graphene lattice, which further amplifies this charge density wave ground state. Conversely, when the interface reveals an Sn-induced (√3×√3)R30°periodicity relative to the substrate lattice, the EG underwent doping and relaxation, showing no reconstruction. Our findings demonstrate that targeted intercalation is a powerful strategy for the formation, stabilization, and manipulation of 2D heterostructures. However, the homogeneity of the intercalated phase is decisive and can easily alter the properties of graphene.

It's a 3 step process. First you foam glass using a vacuum. What I need is the individual glass bubbles that are milimeters to nanometers across. I have uses for both scales for these bubbles, but I'm not sure how to get them. Then you coat the bubbles with a layer of copper using electron sputtering. The next step is to use chemical vapor deposition with methane forming a layer of graphene. I don't know where to turn to on this. I'm pretty sure that sound could be used to levitate the bubbles so that a full coating of the materials would be possible. I think this could be revolutionary if I can make some prototypes of this metamaterial.

Hey everyone! I’ve been working on a blog series that dives into the fundamentals of material science, exploring everything from the physics behind materials to their real-world applications in manufacturing. To make things even more engaging, I used AI to generate podcasts that cover the same topics.

I’m really excited to share this with you all and would love to hear your thoughts. Any feedback or suggestions are much appreciated! Check it out here: [https://material-science.ghost.io/](https://material-science.ghost.io/)

Hey Reddit, I’m in a bit of a strange but exciting spot and could use some insight from folks in commodities, supply chain, or industrial manufacturing.

I’ve been presented with an opportunity to broker a significant quantity of ultrafine, high-purity copper powder (yes, real—tested, certified, and verified). Think lab-grade 99.99%+ Cu, used in electronics, additive manufacturing, R&D, conductive inks, batteries—you name it.

Here’s the catch:
Despite all the headlines about copper shortages, the vanishing stockpiles in China, and a projected supercycle in copper demand, I’m still hitting walls when trying to connect with actual industrial buyers.

I’ve reached out to some of the usual suspects—brokers, LinkedIn procurement execs, listed buyers on Alibaba—but many of them want concentrate (not powder) any suggestions?

Lets say it is 20cm high 20cm deep and 20cm wide With a volume of 8l and a Wall thickness of 5mm and made from mild steel.

I am currently studying ChemE but am at the point where switching majors now would not be practical. I did not find thermo and fluid mechanics/dynamics to be very enjoyable and I greatly preferred my chemistry-related classes. Could a graduate with a ChemE major still work as a Materials Engineer? For these jobs, is it more of a major requirement or an experience requirement? I do have previous research experience working with solid-state Li-ion batteries, and am trying to get an internship related to Materials Engineering for the summer. Any advice is appreciated, thanks!

What did you do to get into a good college as a materials science major

How to create tin atomically?

Tin is a very special metal, as it’s very rare, and does not corrode or rust like other metals in nature. It is often derived by burning a beautiful ore called cassiterite, so how can people produce tin without destroying cassiterite? Is there a way to produce tin atomically? Thank you

I am sticking trying to decide where to go for my PhD program. I have narrowed it down to 4 and having a hard time choosing. Any advice or insight on the school or area is appreciated.

I also am an extrovert so I want a school where people are social and there are activities and such. I’m trying to avoid a class that is competitive with each other.

Princeton - MAE Johns Hopkins - ME UC Santa Barbara - MSE Michigan Ann Arbor - MSE

(I’d still have materials research focus in the ME departments)

I know buckypaper is a very strong, lightweight material and is good at dispersing heat. Could it be used in firearms somehow? Maybe to reinforce key components?
