Advancing small‐angle X‐ray scattering for complex metallic systems: Ti2Cu precipitation in a martensitic near‐α Ti alloy

Journal of Applied Crystallography, Volume 58, Issue 6, Page 2006-2017, December 2025.
A novel small‐angle X‐ray scattering modelling approach is introduced for the analysis of precipitation behaviour in metallic systems exhibiting scattering signals with streaks originating from the embedding matrix. This approach enables in situ tracking of the microstructural evolution, such as the volume fraction and size of second phases, during ...

Space‐time wedges

Nanophotonics, Volume 14, Issue 23, Page 3939-3946, 02 November 2025.
Abstract Space‐time–modulated systems have attracted significant interest over the past decade due to their ability to manipulate electromagnetic waves in unprecedented ways. Here, we introduce a new type of space‐time–modulated structure, the space‐time wedge, consisting of two interfaces moving at different velocities, which results in either closing

Application of metasurface in future displays

Nanophotonics, Volume 14, Issue 22, Page 3527-3555, 01 November 2025.
Abstract Optical metasurfaces, as a booming research field, have provided new methods for modulating the amplitude, phase, and polarization of light through artificial birefringent structures or structural resonances. It has been used to design planar optical components such as ultra‐thin lenses, ultra‐wideband achromatic lenses, and orbital angular ...

The diel niche of brown bears: constraints on adaptive capacity in human‐modified landscapes

Ecography, Volume 2025, Issue 10, October 2025.
Diel activity rhythms, representing the behavioral pattern of the sleep–wake cycle, may be adjusted by wildlife in response to changes in environmental conditions. An increase in nocturnality is typically recognized as an adaptive strategy to segregate from humans and mitigate heat stress. Numerous studies have investigated spatial patterns and habitat

Energy flows in vibrated granular media

, 1998
We study vibrated granular media, investigating each of the three components of the energy flow: particle-particle dissipation, energy input at the vibrating wall, and particle-wall dissipation.

Mirror Descent and Convex Optimization Problems With Non-Smooth Inequality Constraints

, 2018
We consider the problem of minimization of a convex function on a simple set with convex non-smooth inequality constraint and describe first-order methods to solve such problems in different situations: smooth or non-smooth objective function; convex or ...

Model for small‐angle scattering analysis of membranes with protein‐like inclusions

Journal of Applied Crystallography, Volume 58, Issue 5, Page 1571-1581, October 2025.
A general mathematical construction is proposed to add protein‐like inclusions to any pre‐existing membrane model and calculate the resulting small‐angle scattering. The approach is suitable for both elastic and inelastic scattering data analysis.Proteins are ubiquitous in biological membranes and have a significant impact on their scattering ...

Intervention or Non-intervention, the Legalities of R2P and the Human Rights Agenda

Politikon, 2017
The threat of violence alongside the deep-rooted fear of falling into old patterns of animosity and violence have pushed the international community towards stringent controversial approaches regarding international conflicts. R2P initially started as a

Enantiopure Phosphine Oxides with Electron‐Rich Chiral Rhenium Stereocenters: Syntheses, Structures, and Brønsted Basicities

European Journal of Inorganic Chemistry, Volume 28, Issue 27, September 29, 2025.
The title complexes, prepared by oxidations of the corresponding enantiopure rhenium‐containing phosphines, exhibit Brønsted basicities much greater than those of the corresponding triorganophosphines, with ReP(O)R2 systems » than spacer‐containing ReCH2P(O)R2, and C5Me5 adducts » C5H5. The chiral racemic methyl complex (η5‐C5R5)Re(NO)(PPh3)(CH3) (2)

Synthesis of Diaryl‐ and Dialkynylphosphinates From Ubiquitous PV Sources via a Redox‐Neutral Approach

Advanced Science, Volume 12, Issue 36, September 25, 2025.
Classical strategies for P─C bond formation rely on precursors (e.g., PH3, H2PO2, PCl3) obtained from P4, which is produced via the energy‐intensive thermal process. Here, an alternative, redox‐neutral approach is explored. Primary phosphate sources are activated with triflic anhydride (Tf2O) and 4‐dimethylaminopyridine (DMAP) to a versatile PV ...
