Unveiling the impact of trivalent metal cation transmutation on Cs$_{2}$AgM(III)Cl$_{6}$ double perovskites using many-body perturbation theory
Lead-free halide double perovskites A$_{2}$M(I)M(III)X$_{6}$ have garnered significant attention in the past decade as promising alternatives to CsPbX$_{3}$ perovskites, addressing concerns related to lead toxicity and material instability. In this work, we employ a trivalent metal cation transmutation strategy to design a series of inorganic Pb-free halide double perovskites Cs$_{2}$AgM(III)Cl$_{6}$ and perform a comprehensive investigation into their potential for applications in optoelectron…

I sometimes wonder if somewhere around y2k I slipped through a cross-timeline rift, coming from a universe in which the Oasis bros killed each other before forming a band.
Seriously, this story included 4 clips from Oasis songs and I didn’t recognize ANY of them. I don’t recall ever hearing of them until recently. Not particularly impressed either, although there was a lot of drunken Brit crowd participation in the clips.

Oasis returns to Wembley Stadium
At the Oasis reunion in the U.K., we hear from fans and journalists about why the band's comeback has garnered so much attention.

I finally finished the blogpost including some new photos and a short video (!!) from my hike last Saturday.
To me it was a really really gorgeous day!

So, the maga-nazis go after universities because students question (as I do) the genocidal policies and acts of the government of Israel (as distinguished from the people of Israel) against Gaza.
Yet they fail to repudiate, or even question, those who clearly hate Jews and open espouse repressive measures.
And shame on Google/Alphabet/Youtube for feeding this troll who openly has profited from violations of Youtube's proclaimed (but apparently merely proclaimed but not enforc…

You know, “this” used to be a perfectly innocent word. Nothing special, but a solid citizen of the grammar ecosystem. Who could have predicted it would turn into a major clickbait villain, meaning “We’re not going to tell you what this article is about until you click on it.”
FWIW I think I’m not alone in consciously avoiding clicking on such links.

Hi friends!
I set my alarm to 5am and headed out for a nice walk. It was getting warm, so I started early. - and it was just so good to do so!
A nice 6h walk with lots of views, lots of photos and just enjoying being out. End the #summit just for me 😍
On the way up I noted all places where I could refuel later using my water filter. Seriously: why didn't I buy that waaays ear…

Body is a bit wrecked from yard work yesterday. Tylenol doing work, but I’m standing up in stages… more so than usual.
I’ve run out of mulch, which was expected. Whoever did the original landscaping surely hired it out because there is an unholy amount of mulch beds. I’ll probably look to cede some of that back to grass in the future.

Photonics in Flatland: Challenges and Opportunities for Nanophotonics with 2D Semiconductors
Two-dimensional (2D) semiconductors are emerging as a versatile platform for nanophotonics, offering unprecedented tunability in optical properties through exciton resonance engineering, van der Waals heterostructuring, and external field control. These materials enable active optical modulation, single-photon emission, quantum photonics, and valleytronic functionalities, paving the way for next-generation optoelectronic and quantum photonic devices. However, key challenges remain in achieving …
