Consistent control of drying rates of solution thin films on wafer-sized substrates by dynamic air-knife drying with optimal trajectories
This work tackles the problem of achieving consistent drying rates of a solution film deposited on a $20\,\rm{cm}$-wide substrate ($\approx $ silicon-wafer size) that is driven under a narrow air flow ejected by a slot nozzle (or "air knife"). The main prerequisite of the work is that the drying rate of the solution film is highly decisive for a certain performance indicator of the deposited film at a particular, critical concentration $c_{\rm crit.}$. Empirically, this concentration can be ass…

I tried vibecoding again. Gave Opus 4.5 what I thought was a fairly hard assignment: generate a TypeScript compiler transform, using ts-patch, to let me mark functions with a magic decorator to make the compiler inline all calls to them.
It one-shot a basic implementation.
Getting to a higher-quality implementation required guidance from me – at times it had bad instincts – but when I gave guidance, it was competent at following it.
Overall, I'm spooked.

What if dinner was public infrastructure - again?
"food charity Nourish Scotland are pushing for the reintroduction of public diners to Scotland: diners subsidised by the state to provide affordable, nutritious, and filling meals that are accessible to everyone regardless of their financial status.
“There's an element of universality, dignity, and quality that comes with something being a public institution or a part of public infrastructure,” said Anna Chworow"

What if dinner was public infrastructure?
A Scottish charity wants to reintroduce state-subsidised diners for all—a potentially a big ask in the current political climate.

And no, apparently this is not a joke.

Three-fold Superstructured Superlattice HfN/HfAlN Thin Films for Enhanced Toughness
To simultaneously achieve high hardness and high toughness in protective coatings remains a fundamental challenge. Here, we harness the superlattice architecture to combine Koehler hardening while the coherent interfaces reduce the crack driving force and improve toughness, enabling coatings that are both hard and damage tolerant. We design and fabricate epitaxial HfN$_{1.33}$/Hf$_{0.76}$Al$_{0.24}$N$_{1.15}$ superlattices, deposited on MgO(001) substrates using low-energy, high-flux ion-assist…

I’ve fallen in love with the Japanese literary form, zuihitsu.
Zuihitsu, meaning “following the brush,” flow as the mind flows. They are fragmentary—mixing moments of observation, opinion, anecdote, asides, and humor. From the contemporary point of view zuihitsu refuse categorization, vibrating in the live space between prose and poetry.

Ways of Seeing: Following the Brush - Zuihitsu as Attention
Zuihitsu, a Japanese literary genre between prose and poetry, is a unique form of attention. Sei Shonagōn and Kimiko Hahn inspire exercises in looking.

Non-Hermitian Skin Effect and Electronic Nonlocal Transport
Open quantum systems governed by non-Hermitian effective Hamiltonians exhibit unique phenomena, such as the non-Hermitian skin effect, where eigenstates localize at system boundaries. We investigate this effect in a Rashba nanowire coupled to a ferromagnetic lead and demonstrate that it can be detected via non-local transport spectroscopy: while local conductance remains symmetric, the non-local conductance becomes non-reciprocal. We account for this behavior using both conventional transport a…
