Magneto‐Spectroscopy of Interlayer Excitons in Transition‐Metal Dichalcogenide Heterostructures

open access: yesphysica status solidi (b), Volume 262, Issue 3, March 2025.
Combining two different transition‐metal dichalcogenide monolayers can lead to a type‐II band alignment and formation of interlayer excitons (ILE). In diselenide heterobilayers, bright ILE are observable if the interlayer twist angle is close to 0° or 60°.

Formulation of perfect‐crystal diffraction from Takagi–Taupin equations: numerical implementation in the crystalpy library

open access: yesJournal of Synchrotron Radiation, Volume 31, Issue 6, Page 1469-1480, November 2024.
The Takagi–Taupin equations are solved in their simplest form (zero deformation) and equations of the diffracted and transmitted amplitudes are obtained using a matrix model. The theory presented is coded in the open‐source software package crystalpy.The Takagi–Taupin equations are solved in their simplest form (zero deformation) to obtain the Bragg ...

New opportunities for time‐resolved imaging using diffraction‐limited storage rings

open access: yesJournal of Synchrotron Radiation, Volume 31, Issue 5, Page 1299-1307, September 2024.
The opportunities for time‐resolved X‐ray imaging at diffraction‐limited storage rings are demonstrated by benchmarking time‐resolved 2D and 3D imaging at ForMAX, MAX IV. The enhanced flux density provided by the MAX IV storage ring allows micrometer‐resolution time‐resolved imaging at 2 kHz and 1.1 MHz acquisition rates in 3D and 2D, respectively.The ...

Estrogen‐dependent gene regulation: Molecular basis of TIMP‐1 as a sex‐specific biomarker for acute lung injury

open access: yesPhysiological Reports, Volume 12, Issue 17, September 2024.
Abstract Increased circulating tissue inhibitor of metalloproteinases‐1 (TIMP‐1) levels have been observed in patients with acute lung injury (ALI). However, the sex‐specific regulation of TIMP‐1 and the underlying molecular mechanisms have not been well elucidated. In this study, we found that plasma TIMP‐1 levels were significantly higher in COVID‐19

Some topological properties of residually Černikov groups [PDF]

open access: yesGlasgow Mathematical Journal, 1982
In this paper we shall indicate how to generalise the concept of a cofinite group (see [7]). We recall that any residually finite group can be made into a topological group by taking as a basis of neighbourhoods of the identity precisely the normal subgroups of finite index.
