Freeze casting—a guide to creating hierarchically structured materials
Freeze casting is an elegant, cost-effective manufacturing technique to produce highly porous materials with custom-designed hierarchical architectures, well-defined pore orientation, and multifunctional surface structures. Freeze-cast materials are suitable for many applications, from biomedicine to environmental engineering and energy technologies.
An article in Nature Reviews Methods Primers now provides a guide to freeze-casting methods that includes an overview on current and future applications and highlights characterization techniques with a focus on X-ray tomoscopy.
"We were delighted when the journal Nature offered us the opportunity to prepare a [Primer] with instructions and an overview of the process," says materials scientist Prof. Ulrike Wegst (Northeastern University, Boston, MA, U.S. and TU Berlin).

Possibly my favorite part of the dwarf commoner origin is that its the most triumphant from the bunch. For the first half of the origin youre playing gopher, its shown exactly how much the people in Orzammar look down on you, and how little mobility you have (Rica is more optimistic, but even she believes that its a long shot to change anything, even though she KNOWS her sibling is worth it! its the nobles who wont see). Youre under the Beraht's thumb, yes, but youre also under the city's shoe more generally. Half the people in Dust Town recognize you as Beraht's enforcer, half the dialogue in the Commons are people thinking you getting too close would get them "infected" or at least looked down upon—your very existance a taboo. And then you arrive at the Proving Grounds, Duncan greets you with blessings, something not afforded to the casteless, and then you walk into the tournament, beating everyone handily (and in one dialogue option rubbing this in their faces!)! And even when you are caught! when they try to get rid of you for stepping out of your place, you kill the man using you to his own ends! and and Rica is fine and safe and maybe happy! and Duncan is calling you couragous and saying a group that half of Orzammar admires would be blessed to have you! You WON!
And then you get to Ostagar, and you lose everything.
like. the epic highs and lows of highschool football have NOTHING on the commoner to ostagar route! maheriel and tabris and cousland and aeducan are playing bad things happen bingo! amell and surana are on the worlds worst graduation bender! but BROSCA! brosca my BELOVED. the bigger you are the harder you fall!

oswlld's monthly wrap up: april
note: i am trying something a bit different this year, so bear with me as i figure out how i want to format this. i wanted to spend more time sharing what i consume, beyond what i rb, and put my thoughts in one place. these posts are okay to rb
--
This Is How You Lose the Time War, Amal El-Mohtar & Max Gladstone [started 04/04, finished 04/09] *drags my hands down my face until the end of time* I want to meet you in every place I ever loved. I want to meet you in every place I ever loved. I want to meet you in every place I ever loved. I want to meet you in every place I ever loved. I want to meet you in every place I ever loved. I WANT TO MEET YOU!!!! IN EVERY PLACE I EVER LOVED!!!!!!!!!!!!! 4.75⭐️ in storygraph. — Hamnet, Maggie O’Farrell [started 04/12, in prog] I am about 100 pages in and still not sure if I want to keep going or DNF it. idk what isn’t sticking because the writing is beautiful and the pacing is great. And I do care about the characters, I really do. I love the way the author borrows from future grief, it’s what I am enjoying most about this read so far. Maybe I’ll give it 50 more pages and see if it finally sticks.
23.5 Degrees, GMMTV [started: 03/08, ongoing] As mentioned, I am caught up on eps 3-8. I’ll likely not be able to watch it live in may but I will be keeping up with the series til the end. It’s so lighthearted and charming! Not sure how they managed this, but I am constantly surprised by the character group dynamics. It’s def due to the great chemistry everyone has with literally everyone. I need NEED to discuss the score of this show because it’s IMMACULATE. The celestial themes, from the props all the way down to the music, is so rich. I’m so excited to see how this story unravels. — Devil’s Plan [started: 04/23, ongoing] This is a bestie pick, a show my best friend chose to have us watch on our facetime calls. We are 1.5 eps in and it’s a grower. The first game is hella complex and we’re slowly picking up on what’s happening. The people on this show are incredibly intelligent, so I feel like I have to work extra hard to keep up. It does feel rewarding, I’m hooked.
Oppenheimer, Peacock [watched on 04/05] I am a self-proclaimed Nolan girlie, I’ll admit it. I do enjoy his work and the many ways he translates time into film. When I wrote this, it had been a few days since I watched it and I still think abt the little moments that blew me away. Moments like the accentuated dust particles, how the coloring of the movie can be an unreliable narrator, and the utilization of a crowded hall stomping their feet to create tension. The last eight minutes still haunts me. I find more value in the technical side of film, but I will give credit when credit is due: every award Cillian Murphy got this season was so well earned. He carried all three hours of that film with such powerful quietude. And lastly, my heart now belongs to Jennifer Lame. Upon seeing her accept the award for Best Film Editing for Oppenheimer, I have come to learn that she also edited Tenet. HER MIND!!! She has such a bright future ahead of her, to be up there with the minds of Thelma Schoonmaker and Anne V Coates. — Yellow Door: ’90s Lo-Fi Film Club [watched on 04/14] This film needs to be studied in film school. It’s incredibly meta in some ways, having renown directors be the subjects, talking about their passion for film. The production being so stylized and the editing feels very reminiscent of Our Beloved Summer, with the way the found footage and the aspect ratios are intertwined with current day quality shots. This film will hit everyone right in the millennial. A true surprise for me is discovering that Bong Joon Ho and I are more alike that I had originally thought. The way he speaks in casual conversation and his story of setting strict rules for their film collection had me hollering because SAME. The most jessi thing he recounted was how all the VHS tapes were labelled. Yellow Door is somehow the opposite of the "doesn’t take itself too seriously" mentality; it’s actually so great that they made the film like that. By fully immersing us with gorgeous cinematography, cheeky editing sequences, and lush music to tug at your heartstrings, it bewitches you into loving film as much as they did. And still do.
Cowboy Carter, Beyoncé [relisten] I’ve given this several good cycles to confirm my first impressions: it’s def one of her most cohesive albums to date and still stands as a spectacular album. This passion project of hers takes such great care and attention to the voices she amplifies. I can feel the hunger, the innate need for her to make this album. If you haven’t heard how this album came to be, I insist you take the time to educate yourselves. It makes the listening experience so much more empowering. Good for her… GOOD. FOR. HER!! Current favs: Ameriican Requiem, 16 Carriages, Bodyguard, Jolene, Spaghettii, Ya Ya, Desert Eagle, II Hands II Heaven, and Sweet/Honey/Buckin’. — Older, Lizzy McAlpine [first time listening] Coming off the heels of my Five Seconds Flat hyperfixation last year, I haphazardly went into Older hoping its a natural progression in production value. I was shocked that it turned out to be a completely different sound. I soon learned that she actually didn’t really like how Five Seconds Flat was produced because it didn’t feel true to her as an artist. Tbh I was feeling a little lost after the first listen but after digesting this new info, I went back into it and appreciated it a lot more. In fact, the third listen was when I realized that it gave off the same energy as Laufey. I’m excited to listen to it again soon. — Stick Season: Forever, Noah Kahan [first time listening] Having stumbled on all the collabs on Alexa earlier this year, Forever was the only new song for me from his latest release. I’m OBSESSED with this song!!!! The way his voice carries the entire weight of every hurt inside me and just takes it away. Something healed in me. I play it in the car every time I leave the house. I cry in the car every time I leave the house. — The Tortured Poets Department, Taylor Swift [first time listening, standard vinyl ed.] I am going to get this out of the way and say that this album is great. Just great. I understand more than ever why she felt the need to make this album. Having only listened to the standard version a couple times and the anthology twice through, I sit here in this kind of… discomfort. And I’m kind of okay with that feeling. But… it pains me that I can’t share this album with some people in my life and it’s largely due to how she depicts her struggles with people with mental illness/addiction. It’s one, if not the biggest, strike I have against this album and by extension, her. Songs cycling in my head: Down Bad, So Long London, Guilty as Sin?, Who’s Afraid of Little Old Me?, loml, imgonnagetyouback, Chloe or Sam or Sophia or Marcus, How Did It End?, I Look in People’s Windows, The Prophecy, Peter, and The Manuscript.
EXPO Chicago [attended 04/13] Yes, I am doxxing myself a bit if you didn’t already know. During college, I used to attend EXPO yearly and occasionally went back long after I finished school. I haven’t attended in a long time, so I made it my goal to attend this year. And I had a blast! My mother tagged along and she’s not one to attend shows like this or art museums in general. It was a beautiful day trip to the city and it was nice to have her company. She mostly trailed behind and took pics of me as I floated around the exhibition hall. I have 50+ artists I tracked on my phone to actively research in my spare time. I sat in on one of the panel talks (ON COLOR), discussing color theory in today’s bipoc landscape. I took so much away from that conversation, it was very charged. I'm kinda obsessed with Alteronce Gumby, I need to do an artist deepdive on his work. — Coachella [watched from 04/12 to 04/14] I work for a big tech company and one of the biggest events to be on standby for is Coachella. I had to be on call for Friday and was backup support for Sunday lineups. Thus, Saturday was the only day I could sit back and relax while watching. My first time lineups included: Hatsune Miku, Peso Pluma, Late Night Drive Home, Jon Batiste, Ateez, le Sserafim, Purple Disco Machine, Bleachers, No Doubt, 88rising Futures, and Latin Mafia. Of all of the performances, I want to take a full deep dive into Ateez and Peso Pluma’s discography in the near future.
