What's your favorite metal (pure elemental as well as alloy)?

Terribly sorry, this got lost in my drafts and has been sitting there for months! Oops!

Great question, though, thanks!

I have a fondness for titanium and titanium alloys (Ti-6Al-4V), simply because that's what I have the most experience with, I know the microstructures it can form, processing methods, phase transformations, etc. So titanium is at the top of my list.

But, honorable mentions:

Cobalt. I really like cobalt blue. And cobalt is a cool element by itself.

I also really like tungsten. Not sure if it's the name/symbol combination, or if it's just the heaviest element I'm probably ever going to hold (I mean, there's gold, but, eh. Gold's more impressive for its non-reactivity.) in a decent size, or if it's all of tungsten's many "awards" (highest melting and boiling points). Or maybe I just think refractories are neat.

Gallium. Melts at/near room temperature. Liquid metals are cool.

Tin. Its near room temperature phase transition is really neat. Love to see it in person some day.

High entropy alloys. Also very neat.

But I'm going to cut this list off here before I start talking about reasons to love every possible metal/alloy.

(...do metallic glasses count as alloys? 😁)

Obviously it's not out yet - but is this something the MSE community here on tumblr would be interested in?

Another idea: Communities on Tumblr

For a while now folks have asked us for better ways to connect with other people who share similar interests. We’re listening, and at Labs we’ve been looking into fulfilling that need, Tumblr style.

Introducing Communities, a new place to connect with others on Tumblr:

Here in Labs, we’re working on big ideas that could transform how Tumblr is used, while keeping that Tumblr vibe alive. You can see one of those ideas above. We’re calling it “Communities”, a new dedicated space on Tumblr for people to share and discuss all the content they love. Communities can cover topics like your favorite show, artist, movie, video game, your school, your board game group, friend group, big or small, whatever you want.

Each Community has their own semi-private safer space away from the regular dashboard where you can interact with other Tumblr users who share the same interests and passions as you. There are moderators and members (you!), rules, and privacy settings. Each community has its own feed of posts from members, separate from your Following and For You feeds. Interactions within community spaces stay there and replies will work more like a traditional comment section. Folks will be able to reblog posts into a community, but not out — at least not yet.

We’re very excited for you to try it, and help define the best path forward. What we have is a prototype to help us validate the idea, but there’s still plenty of questions that need answering. Over the next couple of weeks, we’ll be reaching out to people across Tumblr, and the internet at large, to try our prototype. Based on the feedback we get, we’ll iterate on the idea to see what resonates best with all of you on Tumblr.

If this sounds interesting, please like, reblog, or reply to this post, and we’ll invite you to beta test this feature when we roll it out to a wider Tumblr audience, as a little perk for following the Labs blog.

Stay tuned for more!

This is REALLY COOL! Unless I’m missing something obvious, this looks to be an incredibly green, easy to use process. Maybe we’ll start seeing wooden skyscrapers one day! @agendermetalbender and @materialsscienceandengineering might enjoy this article!

[camerapits]

@materialsscienceandengineering - Turns out there is a How It’s Made episode describing a very similar process to what I did in research and LANL to make MoS2 transistors. This would’ve come in handy to help illustrate my work…

@materialsscienceandengineering is this your field in a way?

A company making wooden wind turbine blades has successfully tested a 50-meter-long prototype that’s set to debut soon in the Indian and European markets.

Last year, the German firm Voodin successfully demonstrated that their laminated-veneer timber blades could be fabricated, adapted, and installed at a lower cost than existing blades, while maintaining performance.

Now, Voodin has announced a partnership with the Indian wind company Senvion to supply its 4.2-megawatt turbines with these wooden blades for another trial run.

Wind power has accumulated more than a few demerit points for several shortfalls in the overall industry of this fossil-fuel alternative.

Some of these, such as the impact on bird life, are justified, but none more so than the fact that the turbine blades are impossible or nearly impossible to recycle, and that they need to be changed every 25 years.

Wind turbine blades are made from a mixture of glass and carbon fiber heated together with sticky epoxy resin, and these materials can’t be separated once combined, which means they go into landfills or are incinerated when they become too battered to safely operate.

GNN has reported that folks will occasionally find second-life value in these giant panels, for example in Denmark where they are turned into bike shelters. In another instance, they’re being used as pedestrian bridges.

But there are way more wind turbine blades being made every year than pedestrian bridges and bike shelters, making the overall environmental impact of wind power not all green.

“At the end of their lifecycle, most blades are buried in the ground or incinerated. This means that—at this pace—we will end up with 50 million tonnes of blade material waste by 2050,” Voodin Blade Technology’s CEO. Mr. Siekmann said recently. “With our solution, we want to help green energy truly become as green as possible.”

The last 15 years have seen rapid growth in another industry called mass timber. This state-of-the-art manufacturing technique sees panels of lumber heat-pressed, cross-laminated, and glued into a finished product that’s being used to make skyscrapers, airports, and more.

At the end of the day though, mass timber products are still wood, and can be recycled in a variety of ways.

“The blades are not only an innovative technological advancement but a significant leap toward sustainable wind production,” said Siekmann, adding that this isn’t a case of pay more to waste less; the blades cost around 20% less than carbon fiber.

Additionally, the added flexibility of wooden blades should allow for taller towers and longer blades, potentially boosting the output of turbine by accessing higher wind speeds.

Now partnered with Voodin, Senvion will begin feasibility analysis in the next few months, before official testing begins around 2027.

2025 Monthly Topic Poll

As mentioned previously, 2024 is rapidly coming to an end - and that means the end of the 2024 daily posts! Next year, every three months (March, June, Sept, and Dec) I’ll be posting about an MSE topic at least every other day - and it's time to vote on topics! Top four topics will win, unless it's ambiguous, in which case I'll run another poll (or if there's no interest in any of them!)

More explanation for each topic is under the cut:

Acoustics and sound: All about acoustics in materials science, and also the materials science of acoustics, anything from ultrasonic testing to the science of musical instruments.

Atoms: The science of things at the atomic level; electron energy levels, protons, neutrons, isotopes, etc.

*Careers: This one would require input from followers, but would include posting on what kind of careers exist that involve materials science, however directly.

Color: The sources of color in the world around us. Incandescence, color centers, structural color, etc.

Computational materials science: Different techniques and methods of computational materials science

Data: Presenting data, managing data, collecting data, etc.

Elemental groupings: What are the halogens? The refractory elements? Noble metals?

Energy sources: Where are we drawing energy from? What types of solar power exist? What's the status of tidal energy generation?

Integrated circuit (IC) failure analysis: Exactly what it says on the tin, failure analysis of integrated circuits.

Materials maturity levels: Also manufacturing readiness levels; how do we go from testing a new material in the lab to mass production?

Property prefixes and suffixes: Is piezoelectricity the only piezo- property there is? What is the prefix tribo-? How many types of magnetism are there?

Transmission electron microscopy: All about the ins and outs of how transmission electron microscopy works and the different varieties and forms of it.

Anyone interested in trying out a tumblr community for materials science and engineering?

[materialsscienceandengineering]

Polymers, amirite?

(I am a biotechnologist that would very much like to make us better at recycling plastics by making microbes eat them and spit out their component bits so we can reassemble them as needed)

Polymers for sure! 💜 (I say as someone who took one organic chemistry class and immediately locked in on the metals/ceramics track at my undergrad institution...)

No, but seriously, polymers are cool! Polysiloxane anyone? I also have an irrational fondness of polyurethane because it's fun to say. And who's not a fan of rubber?

(I think we would all like to get better at recycling plastics for sure, but I think there's good progress going on on that front!)

The end of 2024...

Hello everyone! 2024 is rapidly coming to an end - and that means the end of the 2024 daily posts! I've got an idea for next year, which is every three months (I'm thinking March, June, Sept, and Dec) I'll pick an MSE topic and post about it at least every other day (so, at minimum, ~15 posts a month, likely more if the topic has enough to generate that many posts). I have ideas for topics, but I don't want to post things that you may not be interested in.

Please let me know your thoughts! Whereas the 2024 daily posts were short snippets, these would be longer, more in depth posts on whatever the topic is, and the topics would be fairly specific (like, transmission electron microscopy specifically, instead of materials characterization overall) (i.e., "metals" is too broad a topic). That's why I'm not committing to another 365 posts!

And if you have ideas already, feel free to send a message, an ask, or just reply here!

[materialsscienceandengineering]

Merry March everyone! Based on a poll I ran back at the end of 2024, expect plenty of sound and acoustics themed posts this month. Not every post will be on these topics - there will be regular posts interspersed - but it'll be the general theme for March.

I'll be using the tags #March25Reblog to reblog old news articles from this blog that are relevant, the tag #March25Posts for new posts I write (which will also have the usual #MyMSEPost tag), and feel free to check out the #Sound and #Acoustics tags as well!

[materialsscienceandengineering]

With the start of 2025 comes the end of the 2024Daily posts. Hope you enjoyed the themes this past year!

Safety Sunday

Measurement Monday

Transformation Tuesday

Waste Wednesday

Thermodynamic Thursday

Failure Friday

Scientist Saturday

hey i just want you to know that even if i don't reblog or like a lot from you i still love your blog. it's incredibly reassuring to see so much innovation and inventions when the rest of the world is mostly occupied with the negative aspects of humanity. thank you for running this blog.

Thank you so much! Absolutely no worries here - I'm well aware this is a science blog on 2024 tumblr. Most people that like to follow science blogs (myself included!) just like to absorb the information without reblogging posts onto their non-sciency blogs, which is a perfectly fine way to engage with this blog. There's no right or wrong way to follow me - but thanks for the kind words and checking in!
