Hey Everyone, I'm currently in a MSE grad program and would like to know if there are any potential careers that combine MSE and toxicology. I have noticed some professors from our interdepartmental program research drug delivery and MSE, and am curious if toxicology may also be included. I do plan on asking those professors about their specific research, but would also like to know the options of this community.

Thank you for your time!

Hello,

I am struggling to find commercially available material to EPU by carbon3D, their material is proprietary

EPU materials: https://www.carbon3d.com/materials/epu-40

I'm trying to create a inexpensive plastic bladder to seal a consumer product. The film for the bladder must be water resistant, durable (puncture prooof) and be easy to seal (prefer impulse sealing over adhesives or RF welders. I've tried 3.5 mil off-the-shelf Polyethelyne (LDPE), but it is not durable enough. Unfortunately the LDPE easily punctures in those areas that are folded/stressed due to "normal" handling of the material.

I think I've got my choices narrowed down to PTU and HDPE as both of these materials are more durable and are easily sealed with impulse sealers.

1. Anybody have any suggestions for other commercially available films?

2. Are there formulations of LDPE that may be more durable?

3. Anybody have suggestions for where I can obtain samples of PTU and HDPE? (I need approximately 20" x 20" of each type AND I don't mind paying for the samples. I'm trying to avoid buying a large roll and the associated shipping cost.)

I am DIYing an outdoor portion of a Cafe and have a choice of two materials in my area.

1. Polycarbonate (PC) 0.8mm
2. Polyethyleneteraphtalate (PET) 1.1mm

Both choices are optically clear, but we absolutely need Ultraviolet (UV a, b, c?) blocking/protection for customers and furniture/equipment.

Infrared (IR) radiation blocking would be a good bonus to reduce heat.

Any advice would be greatly appreciated, thanks in advance!

I am looking to build a perimeter that will encase a 15x45 solar panel. Basically imagine a photo frame with no backing so it is just secured around the perimeter of this panel. This will either be made as multiple pieces that fit together or two pieces: 3 sides together forming a U shape (|____|) and the top piece that joins separately so I can slide the U piece and then secure the top piece.

This will be used outside, where it will deal with the elements. I need a material that will not deteriorate in UV and is not porous, so no water getting through. I also need it to be rigid and stiff while not being brittle. I want to 3D print it, I have access to a Stratasys Fortus 450 mc, an industrial 3D printer. I am fine with putting on some kind of coating for water-proofing, UV resistance. Once its one the panel, it will only deal with static forces besides rare weather phenomena like hail.

The frame is not very thick so I didn't want somehting that would flex too much because it may make putting it on the panel difficult. So would petg or abs be the best material for this?

I am pursuing an undergraduate program in metallurgy and materials engineering in India. I am in my first semester, Hence I am in the process of finding my career path for the next 4 years as an undergrad and then postgrad as well. I am interested in pursuing material science research related to space exploration and the space sector. I have a plan to pursue a master's in Material science, But I am confused as to how to approach it

I would want advice on the following:

1. Which specific research areas/domains of material science would be about my career goal

2. What extracurriculars would be suggested to be done with academics and how to manage both academics and extracurriculars

3. How to approach professors for research opportunities and research programmes after I've decided what I am interested in

Any Other Advice which I missed asking here, But which is very important for my career will also be very helpful to me.

The school I am in offers a materials science degree but they dont give it solely and I have to take it with either applied phys or chem. I like both fields (which is half the reason why I want to get into materials anyway) but I'm still in a dilemma on which one to choose that 1.) would probably help me more in studying MSE (such as similarity of topics covered), and 2.) a more feasible? practical? degree to get as a fallback in case i fuck up in mse or something lol.

some other things

• i've heard feedback from ap/chem mse upperclassmen and most said to pick chem mse instead, since apparently it's "easier" for mse
• i'm considering chem mse now (by like 5%) mostly because of the above but i feel like that reasoning's kinda stupid since nothing in chem or physics would be easy lol
• however... i like physics (theoretical) more than chem, BUT i enjoy the "hands-on"ness of chem more (labs)

obv i wont let a reddit post decide for my future but i kinda need other perspective in this since it's been bothering me A LOT. like genuinely idk what to decide on and it's frustrating lol

suppose zinc powder is prepared in a centrifugal atomizer. can the zinc powder then be heated in a furnace to convert such zinc powder into zinc oxide powder.

an Apple laptop weighs 1.2kg. another Dell laptop weights less than a kg. technologically, they are like million times more advanced than a so-called "TV technology".

yet a 50'' TV weights 15-20kg. why can't it be made with some light weight alloy and post-assembly be under 5kg? given the weight of 55'' OLED panel (its major component) is approximately 2.3 kg..

Hi guys,

I am currently working on an heated enclosure. I am heating it using a silicone heating pad (max 180 degrees c) . I plan to keep my enclosure within 20-100 degrees c.

Is it safe to put the silicon heating mat between 2 pieces of polycarbonate sheets with some insulation inbetween?

The silicon heating mat will heat up one of the pc sheet’s directly.

Thanks!

Hi, I'm an API and National Board Commissioned inspector with an NDE background and I would like to grow my knowledge of Materials Engineering and eventually work as a consultant doing things like performing Damage Mechanism Reviews, but I need to know a lot more. Can anyone suggest an online degree in MSE? If not, I typically take 1 - 2 industry recognized courses per year so I am open to alternate suggestions.

I've been using hot glue to glue small LED's together, then putting them in mineral oil. But the mineral oil dissolves the hot glue/causes it to not stick anymore. Any ideas for easy to use non-conductive liquid, readily available like mineral oil? I'm using the liquid as ballast, so heavier is better. Thank you.

I recently discovered Nitinol, a Shape Memory Alloy, This thing memorizes its shape, If you fold it or bend it in some way and expose it to heat, it comes back to its original shape. You can see what it looks like in this video: https://youtube.com/shorts/Z11Pl5hGX3c?si=72ovSrpho5i-KDiW, So what I was thinking was, I want to create a surface, which can't crack. My idea is, we embed Nitinol in some into the surface, and whenever it changes shape (i.e. Cracks or bend or smth), we can just bring it back to normal by heating it.

I have an offer to go to Manchester for chemistry but idk if I should do materials science, doing so would require a gap year btw

Absolutely love everything about chem (phys,inorg, org, practicals in all phases from the broad to the detailed). Love maths.

I kind of like solid state things (not too deeply but think they’re kind of interesting) quite like continuum mechanics (stresses strains, elasticity) and appreciate engineering principles.

Job prospects wise: I am into nuclear energy (chem is useful for this), and general materials maybe semiconductors (MSE is useful for this), I’d only do pharmaceuticals if I was employed by a high paying company

Given what MSE is like and the extent of my interests (ie how much I like chem and to what extent MSE would fit my desires) and job prospects that I’m after what is the right decision for me? Is MSE suitable for an all round chem enthusiast?

What is the difference between ASM handbook volume 1 and 1A? Does 1A have anything that 1 doesn't have? Do I need to buy all 43 books in the ASM handbook set? Or just buy 24 main books?
