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.

Working on something right now and am trying to pick between two platings on a steel part. Will be exposed to temperatures likely somewhere around 500F. Does anybody have any insight on which of these two options will either maintain their properties best at this temperature, or maybe which one will absorb less heat?
I have created an idea for a road that can prevent damage from taking place due to thermal cracking. Now, I want to make a model with all the properties of my road and make it go through the test of thermal heat transfer and stuff like that because I don't have the capabilities to create the model irl and test it irl.
I tried it. I am no good at coding and computers. I used to dream even of a PhD but now I do not. Every research seems computational.
I suffer from allergies to epoxy resin, nickel and carbamix (Diphenylguanidine, Zincdibutyldithiocarbamate, and Zincdiethyldithiocarbamate.).
I’ve been trying to identify problem products and am finding it hard to learn what is used and where. For example, I am allergic to my PS5 controller which seems to use an ABS plastic shell. Similarly, I’m starting to wonder if my PBT keyboard is causing me issues.
The problem is I lack the knowledge to know if any of these ingredients are used in ABS or PBT in general. I email companies and ask but many can’t help me or they will provide a list of ingredients that I can’t even confirm if they are safe.
Are any of my listed allergies typical used in ABS or PBT? Especially in a way that I may touch that part, as one company told me Epoxy can be used in bonding PBT but not in the PBT itself. I didn’t fully understand how that would effect me.
Hello,
I am working on a project to develop a phase change material (PCM) with a melting point around 5,10,15°C and a latent heat of fusion exceeding 200 J/g to produce cold packs
I would appreciate guidance on the following:
1. What additives can improve the stability and thermal conductivity ?
2. What encapsulation techniques are suitable for preventing leakage during phase transitions?
3. Are there recommended suppliers for base Material and additives like fumed silica or graphite powder?
Any suggestions, references, or insights based on your experience would be highly valuable.
Thank you
Buildings are responsible for 39% of global greenhouse gas emissions, with 11% stemming from the materials and processes used in construction. Addressing these emissions requires informed material choices to minimize environmental impact.
Key discussions in sustainable construction focus on decarbonizing building services through smarter energy management, as emphasized by Schneider Electric, and scaling low-carbon infrastructure, a priority for organizations like Arcadis, which explores strategies to enable large-scale reductions in embodied carbon. Designing for sustainability is also critical, with firms like Gensler highlighting the importance of material transparency and carbon considerations to ensure future-ready buildings. Practical approaches to enhance material reuse and recycling are being demonstrated by tools developed by the Hilti Group, which assess products based on multi-attribute sustainability.
These efforts align with broader initiatives such as embodied carbon reduction goals and fostering a circular economy in the built environment. Learn more about reducing construction emissions through resources like environmental product declarations and life-cycle assessment guidelines.
What are your thoughts on practical steps for reducing embodied carbon in construction?
not sure if this is a good sub for this, but im doing a CAD diagram for a bin, material on website says durapol. seems to be something the company (glasdon) make themselves, so isnt on fusion's database of material. does anyone know what material i should choose (from the fusion library) which is most similar? it is described as "polymer formulated to withstand extremes of temperature" but i dont know much about materials to understand what type of plastic that makes it. sorry if this is a dumb question im a first year in uni idk about materials yet :,) thanks

Hi? I'm working on creating a material or device that can visually indicate the presence/concentration of oxygen without requiring complex instruments. I considered using copper, but it seems it might only work for a single-use application. Does anyone have suggestions for materials or methods that could achieve this in a reusable way? I’d appreciate any leads or insights! Ideally, I’m looking for something akin to a 'mood ring,' but for oxygen detection.
So everyone knows osmium is the densest element. And thus the densest material stable under standard conditions would be the heaviest stable isotope of osmium.
But is making an interstitial alloy of osmium plus some small atom possible, that will be denser than pure osmium?
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
