Advanced Materials Interfaces, EarlyView.Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

A sporting chance for women? Exploring gender imbalance on the sports desks of UK national newspapers [PDF]
, 2016 Sports journalism has traditionally been seen as a male domain, and a number of researchers suggest that this tradition has not changed (Strong, 2007) . Sports reporters in the United Kingdom remain predominantly male, and despite increasingly more women

Area-Preserving Surface Diffeomorphisms
, 2005 We prove some generic properties for $C^r$, $r=1, 2, ..., \infty$, area-preserving diffeomorphism on compact surfaces. The main result is that the union of the stable (or unstable) manifolds of hyperbolic periodic points are dense in the surface.

Tunable Applicator for Microneedle‐Based Medical Devices
Advanced Materials Technologies, EarlyView.This paper presents a simple, low‐cost tunable applicator (TAPP) for microneedle array patches that uses a material‐agnostic controlled‐fracture mechanism to ensure reliable skin penetration and uniform array engagement. The scalable, modular design is compatible with injection molding and 3D printing, can be integrated directly into patches, and is ...

Mechanistic Origin of Photodegradation and Impurity Effects in Donor–Acceptor Luminescent Radicals
Advanced Optical Materials, EarlyView.Purification‐dependent impurities distort the apparent optical and analytical data of TTM‐based radicals without altering their intrinsic photophysical properties. Carbazole attachment elevates the activation barrier of the photodegradation pathway, offering design principles for achieving more robust luminescent radical materials.

Area preserving group actions on surfaces
, 2003 Suppose G is an almost simple group containing a subgroup isomorphic to the three-dimensional integer Heisenberg group. For example any finite index subgroup of SL(3,Z) is such a group.

Advanced Photonics Research, EarlyView.This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

An elementary proof of Franks' lemma for geodesic flows [PDF]
, 2013 Given a Riemannian manifold $(M,g)$ and a geodesic $\gamma$, the perpendicular part of the derivative of the geodesic flow $\phi_g^t: SM \rightarrow SM$ along $\gamma$ is a linear symplectic map. We give an elementary proof of the following Franks' lemma,
