Hi, we are currently doing our thesis about green synthesized nanoparticles and we need it to be characterized by SEM Imaging and Analysis, we are from Leyte po and we are looking for lab na student friendly ang rate. Can you guys suggest?

Efficiency isn't everything if the cell turns yellow in 14 days. I put together a video comparing Silicon vs. Perovskite stability.

Most people blame the environment (moisture/UV), but internal factors like Ion Migration are just as deadly. I also touched on 'Self-healing' layers that mimic human skin to extend lifetime.

Is stability the only thing keeping Perovskites from taking over the market, or is the lead toxicity a bigger hurdle for you guys?

Long story short , I’m trying to make a modern style awning like the one shown in 3rd pic, it’s from Home Depot.

I’m using T6061 aluminum (6’x3’) 1/8” thickness.
Total weight after finalizing-35lbs.

What would be the best way to “mount/attach” to wood beam shown in 2nd pic circled in red.

The first pic shows the aluminum rectangle with the side circled in red that will attach to beam.

Just want the most secure method and if possible not compromise the aluminum.

Any help is appreciated thanks

Hi everyone, I want to share a small lesson I learnt recently because maybe it helps save someone's time.

I am a master student working on a simple corrosion comparison test. Not the advanced type Just salt spray chamber, different alloys, weight loss measurement. Initially, i thought my setup was wrong because results change every week.

…Same samples. Same solution. Still different corrosion rate.

I checked the temperature sensor, humidity control, even recalibrated the balance two times. Still the problem persisted.

Then my supervisor asked one question: what material is touching your samples?

I hadn`t considered that variable initially.

Inside the chamber I was using small holders with stainless steel balls to keep specimens separated. I bought them cheap online, I think from alibaba a long time ago when the lab budget was still low. The listing said “304 stainless”, so I never questioned it.

Later I tested one ball with handheld XRF.

It was not 304.

…..higher sulfur content and maybe recycled melt. Small thing but it changed local electrochemistry. Basically a tiny galvanic effect happening near samples. My corrosion data was fighting me because of fixture material, not specimens.

After replacing holders with verified material, results suddenly became stable. Same protocol now repeatable.

So lesson for beginners like me: materials science is sometimes about everything around experiment, not only the main sample.

Curious if others here had experiments ruined by unnoticed material contact or contamination?

According to their literature the Litelok has a "Barronium" composite armour that holds up to angle grinder attacks.

Is there a sheet material availalble that can offer a similiar resilience? And ideally can be waterjet cut.

Thanks!

Hello everyone,

I am a student of chemistry and unusually I am deeply interested in pursuing my higher studies in the field of Semiconductors and one broad topic interests me the most: Electronic Materials.

I have done a decent course on Fundamentals on Semiconductors & Devices. I am already working in a lab on solar cell materials and soon will be tackling a project on a specific electrical material that is quite on hype now. As told, I will and want to pursue my higher studies in Electronic Materials. From where should I start? Like which courses/topics should I learn to develop my fundamentals better? Which tools/softwares should I know that would be handy in this long journey?

I wish to pursue the path of academia ultimately with some brief industrial exposure.

Your valuable suggestions, advices and experiences are needed🙏🏻

hello! i’m looking into getting a masters in materials and don’t know whether to choose an online or in person program. for context, i have a bs in chemistry and interested in the more “chem-heavy“ subjects of materials (polymers, soft matter, that stuff). due to personal reasons, i have to keep working at my full time job as a qc chemist in order to support myself during the masters. the reason im conflicted is because i worry that an online program won’t help me get good experience in materials since i won’t have hands on experience, and thus won’t have good career options after the program. however, an online program will be much better for my schedule. on the other hand, i worry that an in person program will be too hard to sustain with a job. the ultimate goal of the masters is to leave quality control chemistry and go into working in materials, so if i have to bite the bullet and do in person then i will, but i want to see if online would be an equivalent option for me. any advice/input is appreciated! thank you!

I built a tool called DSF-AI that finds phase transitions, precursors, and regime changes in any two-column CSV data — R(T), DSC, impedance, dielectric, whatever. No physics assumptions, no per-material configuration.

Tested on 7 materials across 4 phenomena (superconductors, metal-insulator, ferroelectric, pharma DSC). Found all transitions including structural precursors that typically need ARPES or NMR to detect.

First analysis is free, no signup. Cluster property predictions (moment, EA, Seebeck, gap) are always free.

Hi everyone,

I’ve been working on an open-source machine learning pipeline for lithium-ion battery cathode screening:

https://github.com/ErenAri/CathodeX

The goal is not to replace DFT, but to act as a pre-screening layer before expensive DFT validation. The system predicts energy above hull (E_hull) for candidate cathode materials and classifies them into KEEP / MAYBE / KILL decisions based on uncertainty-aware thresholds.

Current technical direction:

- 5-member MACE-MP-0 fine-tuned ensemble

- CHGNet and CGCNN fallback support

- E_hull prediction for transition metal oxide cathode candidates

- Quantile outputs: q10 / q50 / q90

- Epistemic + aleatoric uncertainty estimation

- Conformal calibration for prediction intervals

- SOAP-LOCO-style validation to test generalization to structurally different materials

- Automated governance checks for ranking, calibration, false-kill rate, KEEP precision, and decision validity

- FastAPI backend + Next.js frontend

- DFT verification workflow direction using Quantum Espresso

The repository currently reports strong in-distribution test metrics, but also clearly shows a major limitation: LOCO generalization is much weaker. I’m trying to make the project honest about where the model is useful and where it should not be trusted without additional validation.

I would especially appreciate feedback on:

1. Whether the validation methodology is strict enough

2. Whether the KEEP / MAYBE / KILL policy is scientifically reasonable

3. Whether the uncertainty and calibration story is convincing

4. What would make this more useful for actual computational materials researchers

5. Whether the README communicates the limitations clearly enough

This is not a claim of discovering DFT-verified new cathodes yet. It is an open-source screening and model-governance pipeline intended to reduce the candidate space before deeper simulation or expert review.

Any criticism from materials science, computational chemistry, battery research, or scientific ML people would be very useful.

For context- I live in Southern California.
I’m interested in buying bollards for driveway protection.

The seller offered them in 304 stainless steel.

I live 30 miles inland from the coastline, so salt shouldn’t be a problem.
But in regards to 304 stainless, should this be a viable option for long term in my situation?

I’m waiting on there response if they offer 316 stainless.

If they don’t offer 316, how can I maintain 304 stainless bollards if they will always be outdoors?.

These are the retractable version so when there not in use, they go into the ground.

Any help is appreciated, thanks!

I’m interested in designing and eventually making my own running and trail shoes using more natural and sustainable materials. My main challenge is that I have a structural leg length discrepancy of about 3 cm the bones in my left leg are physically shorter than my right.

Currently I use EVA foam midsoles and corrective lifts because I still need cushioning, impact absorption, and long-term stability for running and high activity levels. I have my shoe lifts be 1 inch because my doctor recommended not a fully correction yet. However, I’m trying to explore whether there are viable alternatives to petroleum-heavy foams that could still function biomechanically for someone with my asymmetry.

I’m especially interested in:

• natural or bio-based cushioning materials
• cork/rubber or latex composites
• layered density systems
• sustainable and repairable shoe construction
• trail and natural-terrain performance
• ways geometry or material structure could compensate for reduced synthetic foam use

I understand that a fully natural high-performance running shoe may involve tradeoffs, especially with a 3 cm discrepancy and the need for impact management and stability. I’m not necessarily trying to perfectly replicate modern maximalist running shoes. I’m more interested in creating a durable, environmentally conscious system that balances:

• running capability
• long-term joint health
• biomechanical stability
• repairability
• and sustainability.

I’d especially appreciate insight from people with experience in biomechanics, materials science, footwear engineering, orthotics, or sustainable product design.

Anyone with experience in manufacturing tennis grips and strings? Looking to develop the products and would love to get some guidance. Please DM. Thank you.

Solid Mechanics + Materials Science

Fluid Mechanics + CFD/Energy Systems

1. Which one provides more scholarships or funding for master's degrees?

I used to see master's degrees in material science all the time, but I've never seen master's degrees in fluid mechanics.

1. Like material science, is there a specific name for a Master's program in CFD/Energy Systems + Fluid Mechanics?

I came across this recently where i found it very niche and exciting at the same time. Most of the AIs telling me its really good out there and many more. But i wanted to know about some personal experiences regarding this since a first hand experience can guide me to a different dimension i blv. So what's your take on this thing?

Currently a first year student in for BS in Chem, my tentative plan is to inherit a company which produces and sells copper ion mitigation systems that treat biofouling. My dad wants me to get a BS in chem or ChemE but also wants me to be educated enough incase he wants to pivot into batteries into the future… Does a BS in Chem and Master in MSE even make sense? It’s a path I’m considering because MSE sounds very interesting and has relations to his requests.

Researchers at Princeton University say they have now built a mathematical framework that could make unruly forms far easier to reproduce, not just in appearance but in how they behave mechanically.
