Food Chemistry International, Volume 1, Issue 2, Page 167-182, June 2025.Product identification of flavonoids under weak base conditions and mechanism analysis of dimer formation by the oxidative assembly of quercetin and morin, respectively. ABSTRACT Flavonoids are susceptible to autoxidation in aqueous solutions, which is largely dependent on pH, generating various free radicals and oxidation products. Quercetin and morin

Exciton Diffusion in Two‐dimentional Chiral Perovskites
Advanced Optical Materials, Volume 13, Issue 11, April 14, 2025.Transport of light‐emitting excitons is demonstrated in 2D chiral perovskites via transient optical microscopy. The excitons are found to diffuse rapidly after the excitation followed by localization at longer time‐scales. Temperature‐dependent exciton propagation combined with photothermal deflection spectroscopy measurements reveal the role of ...

The Yenisei Makes the Weather: The Microclimate of the Krasnoyarsk Dam and Its Research, 1960s–1990s
The Russian Review, Volume 84, Issue 2, Page 249-266, April 2025.Abstract When Soviet authorities began building the Krasnoyarsk Dam in 1956, the Yenisei River had an ice‐free period of only 112 days a year. The thick and long‐lasting ice impeded dam building and navigation. However, as the dam rose, it produced an environmental anomaly; for more than 200 kilometers downstream, the Yenisei became ice‐free year‐round.

Magneto‐Spectroscopy of Interlayer Excitons in Transition‐Metal Dichalcogenide Heterostructures
physica 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°.

Locally finite groups containing a $2$-element with Chernikov centralizer [PDF]
, 2015 Suppose that a locally finite group $G$ has a $2$-element $g$ with Chernikov centralizer. It is proved that if the involution in $\langle g\rangle$ has nilpotent centralizer, then $G$ has a soluble subgroup of finite ...

Journal 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
Journal 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 ...

Physiological 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
