Nippon Steel’s $14.9bn acquisition of US Steel closed on Wednesday,
confirming an unusual degree of power for the Trump administration after the Japanese company’s 18-month struggle to close the purchase.
Under the deal terms, Nippon bought 100% of US Steel shares at $55 a share, as it first laid out in its December 2023 offer for the well-known and struggling steelmaker.
A press release on the filing also discloses details of a national security agreement inked with the Tr…

Calamus 28 When I peruse the conquered fame of heroes
My surface reading is this is a celebration of the common man, perhaps soldiers, over the more famous generals and presidents. But this commentary encourages me to dig deeper.
First, to highlight the gay text...
the brotherhood of lovers ... Through youth, and through middle and old age, how unfaltering, how affectionate and faithful they were
Very homoromantic language! Male lovers who stay together through their whole lives, affectionate.
The last fillip here is Whitman's own stance: "pensive... filled with the bitterest envy". Whitman admires these lovers and envies them. That's a striking feeling to disclose!

Investigating MAXI J1752$-$457 with NuSTAR in the aftermath of a superburst
We present two NuSTAR observations of the X-ray transient, MAXI J1752$-$457, following a superburst which was observed by MAXI/GSC in November, 2024. NuSTAR follow-up confirmed that MAXI J1752$-$457 is coincident with the previously observed Einstein Probe source, EP240809a. We performed a spectral analysis of the source during both NuSTAR observations, and we confirm that the hard X-ray spectra are consistent with the inclusion of a spherical blackbody component. At about 79 hours after the on…

I just read the story about the Italian kidnapped by a New York couple and tortured to disclose the credentials for his crypto assets - and the first thing that came to mind was XKCD 538 "Security" about the five dollar wrench.
Am I a bad person?

Direct laser ablation of 2D material films for fabricating multi-functional flexible and transparent devices
We present a scalable method for direct patterning of graphite and transition metal dichalcogenide (TMD) films on polycarbonate (PC) and other transparent substrates using fiber laser ablation. This process facilitates the fabrication of various functional devices, including strain gauges, supercapacitors, and photodetector arrays, without the need for photolithography or solvents, thereby simplifying device production and enhancing environmental sustainability. Utilizing roll-to-roll mechanica…

Impact of border defects on the magnetic flux penetration in superconducting films
Defects in superconducting systems are ubiquitous and nearly unavoidable. They can vary in nature, geometry, and size, ranging from microscopic-size defects such as dislocations, grain boundaries, twin planes, and oxygen vacancies, to macroscopic-size defects such as segregations, indentations, contamination, cracks, or voids. Irrespective of their type, defects perturb the otherwise laminar flow of electric current, forcing it to deviate from its path. In the best-case scenario, the associated…

Selenization of V2O5/WO3 Bilayers for Tuned Optoelectronic Response of WSe2 Films
Scalable and controlled doping of two-dimensional transition metal dichalcogenides is essential for tuning their electronic and optoelectronic properties. In this work, we demonstrate a robust approach for substitution of vanadium in tungsten diselenide (WSe$_2$) via the selenization of pre-deposited V$_2$O$_5$/WO$_3$ thin films. By adjusting the thickness of the vanadium oxide layer, the V concentration in W$_{1-x}$V$_x$Se$_2$ is systematically varied. Electrical measurements on field-effect t…
