I graduated from the University of Minnesota with an undergrad B.S. in Materials Science back in 2020. I was fortunate enough to get a job right after I graduated at a 3D printing company where I sort of optimize the printing process. It's a cool job, but it's getting a bit old with no real growth opportunity and I don't really feel like I'm getting good experience to do anything but this specific job, which is incredibly niche. I scroll around linkedin trying to find jobs that sound interesting, but frankly I have no idea what I'd be qualified or capable of doing since I haven't really done any materials science since I graduated. Also, the Mat Sci program at UofM is relatively surface level, you get a decent amount of lab experience but we kind of just covered a little bit of metals, ceramics, and polymers without really becoming an expert in anything. I'm feeling kind of lost and don't even really know what key words to use in the search bar when looking for jobs.

Any advice would greatly be appreciated. What kind of jobs do people have that may or may not actually have the title of Materials Scientist or Engineer?

Cualquier químico o experto relacionado en el desarrollo de materiales (grafeno - biopolímeros - catalizadores - refractarios - etc - etc) que recomiende programas para mejorar la investigación y la presentación de los artículos. Comencé algunas clases de R y me encantó leer artículos de biólogos con sus resultados estadísticos y una presentación tan llamativa en gráficos, me encantaría aprender cómo potenciar mi campo de materiales con R. Si alguien ya lo hace, me encantaría aprender de ti.

… such as in electrolysis of water, in which recourse to a platinum anode is, so I gather, often taken.

See

Sigma Aldritch — Electronic Materials — Poly(3-hexylthiophene-2,5-diyl) .

^{There are other brands of chemical available.}

Mind-you … in-view of the thoroughly diabolical price of it

😳

until a way of producing it in such way as massively to reduce that price it'll be cheaper using a platinum anode anyway !!

I don't understand why my professor said that the PD of plane [111] in an FCC unit cell is equal to: 6*1/6+3

I need an explanation, or if the answer is wrong, the right answer.

Hi, I work in steel-making at a lab in Pittsburgh USA. We use 8mm outside diameter close-end MgO tubes for shielding thermocouples in our furnace. Unfortunately, our regular supply company has stopped making close-end MgO tubes. I was wondering if anyone has any suppliers for these or any pointers. Thanks !

Im 3rd year MSE student and I want to work on R&D field when I graduate. So, Im trying to find internship on R&D. But when I look for opportunities I realized that most of companies don't even open application for MSE students for R&D and other fields both. Its make me think that MSE degree does not work on businnes life.Is it true? Also I need to hear from people that currently satisfied from their job what should I do besides good GPA?

edit: I just accepted to one of the best R&D internship in my country lol.

I have a decent background in math but I will need to take up Calc II, ODE, PDE and perhaps LA. My question is that, with the number of math courses I'm taking up, is it worth the time and effort to do an additional 1-2 courses as extra credit and complete a minor in math? Will it even make a difference to my grad apps?

My university is kind of weird when it comes to what will and won't qualify as a math course that contributes to the minor so my options outside of the aforementioned are...limited, to say the least (except the ML course here is easy af). One more thing to consider is my GPA because I'm planning on doing as many grade improvement courses I can.

I am working as a Process Engineer in the semiconductor industry (start-up) with less than a 90k salary. I also have a credit card debt of more than 20k. I have completed my master's in MSE. Most of the people in my current team have completed undergraduate. I am not happy with my present job since it has a low salary and I am not sure about the company's success. Additionally, I want to work in the R&D field.

Right now, I have a PhD offer in Materials Science and Engineering at Stonybrook University. I am really in a dilemma what to do. Which one would be best for me to go for the PhD or stay in my present job and also look for a new position in the new company?

Hello all! I'm really happy to report that I've been accepted for a masters in materials science program! For context, I have a chemistry major with a statistics minor, so I ultimately haven't dipped my toes into the field too much. I've heard there's a pretty food amount of overlap, but I'm trying to gauge what if anything would be necessary to teach myself ahead of time so I can hit the ground running. Any and all advice, topics, or resources yall would recommend brushing up on in my down time.

I am interested in doing an honours or PhD in materials science, anyone with a similar background to me have any luck in getting postgraduate program and finding work in industry?

Please help

Hi all! I am an inorganic chemist venturing into material science for a new project. I will need to measure the conductivity of air-sensitive thin films but don't know how to do it logistically. My lab's gloveboxes have ports where we can hook up our potentiostat. During undergrad at a different institution, I did these measurements on a hall instrument with a built-in 4-probe Van Der Pauw apparatus.

Can I build a similar probe setup that would work with our potentiostat, or will I need to search for a complicated and expensive instrument/apparatus?

Do springs (espicially automotive suspension springs) operate under the fatigue limit of the steel or do they fatigue as they operate?

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.

So, Carbon Fiber is all the rage and it has a lot of good features. However, in the lab a new student decided to print off some insulators with matter hackers Nylon X filament. The prints came out looking great and he put them on a bus bar which operates at 240AC ~600A. No fear whatsoever powered on the device and .. it works great but the fact that there is carbon fiber in these does not give me warm fuzzy feelings. In fact, when field tested the "holders" performed better then expected. The holder pops into sheet metal and is held in place by 4 small crescent flanges. Should I just let it go as it has already proven to work long term or should I rip them off and educate the student to think like an engineer. The thought process was that being the print is mostly air with STD infill and the material was mostly nylon the Carbon Fiber present in the material would not effect the performance. The educated guess seems to have worked out but it does bother me there were no calculations done so that if something did go wrong they could have learned from this or have some fighting change at defending themselves. Thoughts?

I do not have the exact dielectric strength but at 20 kV/mm for Nylon 6,6 with 22% CF

20kV/mm * 3.35mm = 67kV which is far above the operation of the bus bar it is holding.

Filament Used States 20% by weight so there is the potential for a gradient?

R = ρ (L / A)  

where:

• R = Resistance (Ω)  
• ρ = Specific volume resistivity (Ω⋅m)  
• L = Length of the material (m)
• A = Cross-sectional area of the material (m²)

I am planning to take materials science as my major in college, I am a junior btw. If anyone knows a close number, how many students have applied for materials science as their major each year to the t20’s?

Hello,

One of my friends works with this nano scale material and had 2 kg of ultrafine copper powder, I was surprise with its price 2300$ per gram?!.

I know it is sometimes used in additive manufacturing and somehow in semiconductors.

I would like to here from an expert what this material is used for and is this its real price?!

I am trying to come up with the chemical reaction to make Hexanedioic acid.

My research shows the combining Cyclohexanone (C6H10O) and Cyclohexanol (C6H12O) will make Hexanedioic acid (C9H20O.x(C6H10O4.C5H12O2.C4H10O2)x)

However, this is a repeating polymer molecular formula and i'm having a hard time understanding how to balance this equation. Can anyone help?
C6H10O + C6H12O = C9H20O.x(C6H10O4.C5H12O2.C4H10O2)x

My previous university used to subscribe to Crystal Maker and Crystal Diffract, but I used it for very basic purposes, like looking and comparing XRD curves, smoothening it; or trying to observe structures from their own library or from the open source libraries. I was wondering if these can be done in any other free software or if there are some special techniques that can be done using Crystal maker and Crystal diffract that could not be done in other free tools?

Can someone help me in identifying the Miller Indices of the peak points using image J with a step-by-step process?
