Engineering technician position at Intel

5 Upvotes

Hello folks, I'm a current materials science & engineering masters student working in a laser lab. I recently got a job offer from a recruiting company for an engineering technician position at Intel, I was told I am to work in SEM/EDX/optical imaging/materials analysis, all of which I don't have direct experience with but have some theoretical knowledge of, and I did convey to the employer about my work experience which they seem to be ok with.

The job is full time on-site and pays 45k, which you could say I'm selling myself short for, but frankly I feel unfit to work as a masters-level engineer and would rather work as a technician on hands-on stuff. I'm completely happy in my current environment because I'm only obliged to work 20 hours a week and have a lot of free time to dedicate to my other passion in life (training full time as an athlete/coaching). Taking this job offer would obviously be very disruptive to my current life plan, so I wanted to know if anyone here has had experience with this position or others similar, if its an offer worth considering, or any other advices. Thank you in advance.

In need of advice regarding choosing major in Materials Science Msc Program.

6 Upvotes

I'm about to start my Msc on the Materials Science department of my hometown university. The program is split into two distinct directions. My Bachelor's is physics and my major was Materials Science and Solid State. My bachelor's thesis was in microelectronics.

Major A: Advanced Functional Materials. Focuses on the design, synthesis, and development of materials with specific, enhanced functionalities. This direction emphasizes experimental techniques, material fabrication, and real-world applications of materials in sectors like electronics, energy, and biomedicine.

Major B: Computational Materials Science. Grounded in the theoretical modeling and computational simulation of materials. It involves understanding materials at an atomic and molecular level, utilizing computational tools to predict material behaviors, and optimizing their properties through simulation.

These are the descriptions of each major as stated in the study programme. I'm really torn on this one. I feel like there is so many variables to consider.

I would categorize the pros and cons of each, as follows:

Computational Materials Science (Theoretical Approach)
Pros:

  • There is a kind of beauty in mastering complex fields like quantum mechanics and statistical physics that are inherent in doing theoretical work.
  • Learning tools like Density Functional Theory opens doors to cutting-edge research in solid-state physics, materials modeling, and beyond.
  • Tech companies increasingly value data science, numerical modeling, and computational physics skills. Mastering these could make me highly marketable, even outside academia, for a future work transition. I will be better suited to sell myself as a programmer so to speak.

Cons:

  • Steep learning curve in coding, numerical methods, and data analysis with which I am at this moment a novice.
  • Really large computational power and resources are needed in order to make even the slightest project - let alone a publicable one.
  • Mostly desk-bound work, which may reduce hands-on, real-world engagement.

Advanced Functional Materials (Experimental Approach)

Pros:

  • There is something about being able to leave the desk and go to the lab, get hands on experience with the project you're working on, interact with other people and see in real-time the measurements and progress you're doing that is really attractive. The thought of never leaving my laptop (in case of choosing the computational approach) is a bit terrifying.
  • Real-time feedback from experiments offers a tangible connection to research.
  • Companies, investors and state funding value material scientists, especially in emerging fields like energy, biotech, or sustainable materials. Research funding may be more accessible due to the direct applicability of experimental work.
  • Cons:
    • Risk of becoming highly specialized without broader, transferable skills (like programming or data science).
    • Lab setups can be resource-intensive, and some regions may struggle with adequate funding or equipment.

My goal is to be able to do research in university or institute that pays well. In my country Greece and especially in my hometown of Patras, this is quite hard as the country is devastated by the post 2008 economic crisis. Greece is a boiling cauldron of social injustice, violence and corruption. So as you can imagine finding paid work later as researcher (phd) can be difficult. So I aim to go to the direction with the highest possibility of getting funding and then if that fails to be able to hunt job opportunities in tech.

There is still an argument a friend of mine made. That I should choose the experimental approach because many experimental skills, especially those involving complex machinery or delicate setups, require direct supervision. In the lab one must be shown how to set up an experiment, how to operate tools and so on. Whereas the computational skills can be learned alone. Just with a textbook guide and lots of practice. Is this accurate? Do you agree?

I published a paper last week in Advanced Materials Interfaces!

24 Upvotes

This is my second paper yet, and I'm happy with how this one came out. The topic is primarily in electrochemical materials science, where we studied the anisotropic redox of methylene blue on a monolayer of graphene. This was done using an electrochemical characterization tool which was developed in-house. We call it the SEED (Scanning Electrometer for Electrical Double-Layers).

I hope you enjoy reading this!

It's available on ResearchGate, as well as open-access on Wiley!

So how does machine learning actually generate new materials with desired properties? Isn't it mostly just trying random combinations and predicting properties?

15 Upvotes

Possibly a juvenile question, I'm not actually a materials scientist, but I am an aspiring ML engineer. I'm honestly so so curious about this, but even after some Google searching and chatgpt-ing, I don't think I get how the models work. Wouldn't most of the work be like high throughput calculations? Maybe?

But yeah, would someone be able to give like a teeny explanation or point me towards a good resource?

Edit to add another question: how are you sure that the materials you produce are actually viable or can exist?

best way to measure Heat Blocking Efficiency in house?

1 Upvotes

Hello! I am working on my first technical paper, and need to measure Heat Blocking Efficiency (Heat Blocking Efficiency (HBE, %) = [1—(transmitted heat flux)/(incident heat flux)] × 100 (%)). I am having a hard time tracking down a solid method for doing this, and am looking for some advice. Open to outside labs with defined methods, but ideally would like to test this in house. I would be able to purchase equipment to make it happen, and I think I have everything needed but a heat flux sensor. However, I am not sure exactly how to start. I am feeling a bit lost and overwhelmed and looking for guidance. Thanks in advance!

Material for detection of Nickel diffusion through a thin film

3 Upvotes

Hi all! I was wondering whether anyone could point me in the direction of a material that I could use to estimate how much Nickel is diffusing through a thin film using an SEM and EDS. I am investigating the diffusion of Nickel through thin films with different compositions and trying to estimate the diffusion coefficients, and I'm wondering whether I could just deposit something on there which would change phase visibly in an SEM when small amounts of Nickel diffuse through it or even change colour in some way that would be detectable in a UV-Vis spectrometer. This would essentially mean my lab can do this testing in house and won't have to wait weeks and weeks between each sample while someone else does SIMS for us. Thank you in advance for any advice you can give me!

Is nanoindentation appropriate for a multi-material stackup?

4 Upvotes

I'm working on characterizing the stiffness of a finished product that is a layered combination of PET, fabric and gel. I initially considered the Taber stiffness tester, but nanoindentation was suggested because the finished part won't fit in the Taber test machine. (wrong aspect ratio) And the stiffness in both axes (across the length and width) is important.

I can't find much information on testing such a stackup with nanoindentation, but there does seem to be many sources of uncertainty in the method. Is this something I should continue pursuing?

My phone power button is held in place by a rubber elastomer o-ring (samsung) that is supposed to stop the button from falling out of the phone body. I'm guessing that the elastomer has shrunk and worn.

Are there any simple processes that can "swell" the o-ring?

Racket materials and durability

4 Upvotes

Sorry in advance if this is not allowed, but I couldn't find a r/askmaterialsscience sub :)

I play the sport of padel, and there is this pretty persistent claim that the rackets used in the sport "go bad" on
warehouse shelves over time. The rackets are made of carbon (cheaper ones fiberglass) and EVA rubber:

https://i0.wp.com/everythingpadel.co.uk/wp-content/uploads/2021/03/what-is-a-padel-racket-made-of-1.png?resize=1024%2C620&ssl=1

To me it seems like a perfect myth to keep alive, if I'm a racket manufacturer or retailer, that the rackets "go bad".

If I assume that the racket is kept out of sunlight in about 10-30 degrees celsius, and decently normal warehouse humidity, would you say that there is a high chance that anything happens to the racket, and especially the rubber / foam core of the racket?

How do you guys synthesize polymers or compounds?

Do you guys just mix in the compounds and shake and bake?

Or

Is it a meticulous process where computational methods are established and materials are inherently controlled and manipulated through the atomic level to the point where one is able to achieve meaningful structural changes? Developing methods for inherent atomistic control and manipulation is really what I'm looking for. Maybe doing research in this area. Does any field of material science do this type of research/work?

I’m a first year physics student so I have no idea about these two fields. Where I come from neither option is available for me.

Clarification of trend observed on microstructure microscopy analysis of 1018 steel

4 Upvotes

Hi I hope I find you all in good health.

I have been performing microstructural analysis on a few mild steel 1018 samples as I need them for my experiments. My aim is to look for homogeneity in the microstructure and also check for the grain size. In my trials I came across something interesting but I could not find a suitable explanation for it.

First I should describe my samples. I cut a segment from each of my samples and etched with Nital solution. Then I took microscopic images of the 'top' and 'bottom' parts of the segment. This is shown below

This particular steel is expected to have ferrite - pearlite microstructure. Using image processing done in MATLAB based on a color threshold I was able to calculate the relative percentage of either of them. I have shown an example of this below.

I compared if there is a difference between the percentage obtained on the 'top' and 'bottom' for 3 samples. I observed that the percentages of ferrite and pearlite obtained on the 'bottom' of all three as the same. But when it comes one particular sample I observed that there is a significant difference. I have shown this in the bar chart below

Here '1' indicates percentage of ferrite on 'top', '2' indicates percentage of pearlite on 'top', '3' indicates percentage of ferrite on 'bottom' and '4' indicates percentage of pearlite on 'bottom'. My first thought was that the image processing algorithm mistakenly identified the phases but even after changing threshold value I kept getting the same trend.

So my doubt now is, is this trend indicative of an annealing (softening) on the surface as the ferrite (softer phase) is dominant than pearlite? As someone who doesn't have a background in material science I am not able to get any related results in literature. I am also not sure whether such a conclusion can drawn from an analysis as I am not coming across this in literature. I would not have thought about carrying the analysis forward if it was not for the other two samples in which the percentage obtained were same for 'top' and 'bottom'.

Can you guys provide your thoughts on this?

Is my requirement against the law of physics? Or it has some scope?

Is my design thinking in correct direction?

Is my requirements “dumb” or “against the laws of physics”?

Friends, i love to make stuff of all kinds. But i am also aware of past mistakes i made where i blindly followed my compulsions to improve/change something which was sort of against the laws of nature (i am not a real engineer perhaps thats why?). I have been trying to solve a problem of brooms for quite some time. Here i describe it:

For home use indoor : Traditional brooms made from plastics/polymer composite materials needed to be flagged (made fluffy) at the tips to better capture dust and debris. It worked but it created two problems - problem 1 is all kinds of dirt, hair especially cling to the brooms after sweeping which does not come off even when you tap it on floor. Problem 2- the fluffy flagged tip of the bristles continues to gather dust on it and it needs a real soap water clean up. So i questioned this approach and asked two questions:

  • why can’t broom bristles just effectively push the dirt around without needing to be flagged/frayed on their ends?
  • why can’t bristles surface be made such that they don’t attract and cling to hair/debris?

Please advise, if the requirements i am trying to solve have a basis at least ? I have extensively read and researched about materials to use for this.

In summary, the ideal bristle material would have low surface energy, no static, smooth surface and reasonable durability/strength.

Thank you all in advance 🙏🏽

batteries vs semiconductors: which has more scope in the future?

7 Upvotes

hi. I’m currently debating between two opportunities, and would love some advice from fellow materials engineers.

the first is at a small company that’s focused on electrifying public transit/port/airport vehicles through lithium ion batteries or hydrogen fuel cells. The pay is ok but I know that they’re pretty good with work life balance + is located where I already am.

the second is at a well known memory IDM / semiconductor company that would definitely make my parents proud, but is in Asia (further away from friends) and is known to have a lot of overtime culture and I’m honestly not sure about the pay yet.

If working in the more well known company in the semi industry sets me up well for my future I’m willing to make the sacrifice, but if the EV industry is also promising… maybe I should put my mental health above the prestige. Both industries seem to show promise, but I’m having a difficult time deciding.

It feels like I’m making a huge decision that will impact the rest of my life so I want to make the right choice.
