Reddit for Materials Science and Engineering topics
Materials science - an interdisciplinary field applying the properties of matter to various areas of science and engineering. This scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates elements of applied physics and chemistry. With significant media attention focused on nanoscience and nanotechnology in recent years, materials science has been propelled to the forefront at many universities. It is also an important part of forensic engineering and failure analysis. Materials science also deals with fundamental properties and characteristics of materials.

I have graduated from textile engineering (majoring in wet process). But I am interested in research particularly in composite materials. That is why I need some suggestions regarding what minimum basic things I should know e.g. programming or simulations. Also is there any schools which is less competitive in particular as I think not from MSE background could effect my chances. Thank you.
Hi, I'm a first year PhD- trying to finalize my advisor selection. I'm highly interested in the wide bandgap semiconductor space for power and RF applications, maybe slightly biased towards RF.
My goal for the PhD is to become "well-recognized" in the field- and I'm in a situation where I can work with arguably the best people in the world for these semiconductors. But I have to choose one.
My understanding is that GaN is more saturated, while Ga2O3 is kinda new. But I'm not sure if it's going to see the same success as GaN.
I want to be highly cited, and recognition matters a lot to me.
Can anyone with experience help me make a decision?
I am currently a phd student and i need help in finding the pdf for this one article. My university does not subscribe to the journal and even sci-hub doesnt have access. i have already request full access on research gate and still no reply(?). This article might be one of most important article for my phd research to find novelty. pweeaaasseee help. doi: 10.1039/D2NR04047F
I have a ceramic engineering degree and I make 80k my first year at an aerospace company in rural ny. What is the expected salary progession for a materials/ceramic engineer and how should I make sure I'm always making more money? I got an "exceed expectations" but that only netted me a 4 percent raise and my boss said a promotion is a few years down the line.
Is a imaginary promotion down the line in a few years enough or should I start applying to jobs once I have 2 years if experience to make more money in a field like semiconductor? I really didn't like the way he worded there are a limited amount of people that could be promoted every year and only top performers get promoted. I'm the only materials engineer in my plant and I have to deal with all the ceramics and glass issues from 4 years of no ceramics engineer support.
The idea of working in failure analysis seems very appealing to me. I was wondering what actually working in it was like and if it’s an enjoyable and rewarding career. Thanks!
Let me know if I am in the wrong sub
For the purpose of making a packaging for a perfume bottle design, I want to use concrete, that I would pour into a mould etc, however I think the end result will be too heavy, so I am looking for a different material that has the same finish. anybody could suggest another material or a different kind of concrete used for these things, product design etc, Thank you guys
Hey material friends!
How much physics and chemistry fundamentals does a materials scientist/engineer need? This clearly differs heavily from field to field but I am mainly interested in research on new alloys, composites, and materials that can be used in energy/automotive/aerospace engineering. I could formally enroll in an MSc program in Materials Science at my university but I believe I don't know enough physics and chemistry to really understand the stuff. There are some short introductory quantum mechanics and chemistry courses in the master's program but I can't imagine understanding mechanical and thermal materials properties with my very sparse knowledge of mechanics/thermodynamics.
What study "roadmap" (topics, textbooks, video series, etc.) would you recommend for someone who would have only physics and chemistry knowledge at high-school level (but all the necessary mathematical background), to follow advanced materials science courses on graduate level?
I would refresh my knowledge with the Feynman Lectures books and fill some gaps in my basic physics knowledge. Then I would refresh/advance my quantum mechanics knowledge with Griffiths' Introduction to Quantum Mechanics, and then I would go into Kittel's Introduction to Solid State Physics.
What about classical mechanics, thermodynamics, and statistical mechanics? Should I learn these topics from theoretical physics textbooks like Landau/Lifshitz or similar? Or from more applied/engineering textbooks?
In terms of chemistry, I have no clue where to start.
Best regards and thanks!
Its used with heat tool to melt it and connect hair to make hair extensions for women its like jelly ant yet silicon but when it melts its kinda watery.
Hi I’m applying to schools right now and I want to do Materials Engineering, specifically I think I would like to work in industry either after my bachelors or after a masters. However only two schools let me do Materials Engineering in my state (that aren’t 2 hours away) for my bachelors, NJIT and Rutgers New Brunswick, NJIT’s Materials engineering program isnt ABET accredited (but most their other programs are) but Rutgers does have an ABET accredited program for Materials Engineering. I am leaning towards NJIT as I would either need to commute about an hour to new brunswick for Rutgers or dorm (which i cannot afford), but it being not ABET accredited makes me hesitate. So how much does it matter for a Materials Engineering program to be ABET accredited (I would also like an explanation for how it really works and what purpose it serves, I just hear to not do engineering without it). Thanks !
edit: ALSO, NJIT’s ChemE program is accredited, so if I do that and minor in materials would that be good for a materials engineering career ? Would doing MechE or EE with a materials minor work too? If it helps I would like to work with semi-conductors
See title
X-axis -> TemperatureY-axis -> Energy output due to relaxation process (delta power)
So A is an metal while B and C are alloys and from I understand alloys recrystallization temperature values are larger than metals because impurities cause create accumulation of dislocations.
But I don't understand why B and C's y-axis lower than A's?
Any good YT channels or other resources for learning material science? I'm a chemical engineering major but I need to study some material science.

Looking for sound advice and guidance
Hi everyone. I am an international student who just graduated from Purdue with a professional masters in MSE. However finding jobs has been extremely hard due with all the lucrative ones requiring security clearance and most other ones being citizenship based. My work experience < 2 years(virtue of undergrad internships and grad research) Even though I have a modest 3.4GPA in undergrad (chem engg) , I only managed a disastrous 2.8 in grad school. I am considering going back to school again next Fall with for a second masters(with a focus area) hoping to do exceptional this time. And so whilst I continue to look for work I am also looking for materials/manufacturing engg schools that are within reach/mid-tier that are offer decent courses or research in Batteries/semiconductors/additive manufacturing and industry opportunities upon graduation. I recently took some certification courses on FEA, FMEA and 3D printing and really loved them all! So Im open to Mechanical/Industrial programs too. Since my parents have borne all of my tuition, I can’t afford to ask them to pay anymore. Hence I need genuine recommendations on Universities that either offer grad funded scholarships or tuition waivers through assistantships all across NA or even Europe (preferably just the US). Please be nice!

I'm looking for a non-toxic water-soluble grease that would be of vaseline-like consistency in its pure form, not as a solid in water solution, which could dry out and lose the greasy property. I haven't gotten my hands on heavier PEGS or anything else, but reading about these I get the impression they get doughy rather than greasy as the MW increases. Maybe Van Der Waal's forces make this impossible. BTW, this isn't for a personal lubricant use, but rather as a carrier for a water soluble solid. The amount of solid dissolved would be very small, and would not play a role in the consistency, unlike personal lubricants that use various polymer solids mixed with glycerol. The initial mixing would likely start with the polar solid dissolved in water or another suitable solvent, and then mixed with the greasy component. After this the solvent evaporating would simply leave the solid well-distributed in the grease. The solid would be an insecticide.
Thanks
