Efficient and Tunable Narrowband Second‐Harmonic Generation by a Large‐Area Etchless Lithium Niobate Metasurface

open access: yesLaser &Photonics Reviews, EarlyView.
An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

Novel Sulfur‐Rich Polymers from Inverse Vulcanization as Functional Building Blocks for Photonics

open access: yesMacromolecular Rapid Communications, EarlyView.
Isopropenyl aromatic comonomers, in particular novel 2,7‐diisopropenylfluorene and 2,8‐diisopropenyldibenzothiophene, synthesized by sustainable, facile, single‐step SMCCR from available brominated substrates are exploited in the Inverse Vulcanization process to obtain functional Sulfur‐rich macromolecular materials.

Rapid and quantitative phage susceptibility test by ramanome

open access: yesmLife, EarlyView.
Abstract Antimicrobial resistance poses an escalating global threat, renewing interest in bacteriophage therapy as a precision alternative to antibiotics. However, clinical translation remains hindered by the lack of rapid and quantitative phage susceptibility testing (PST) platforms capable of evaluating host range, infection potency, and effective ...

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

open access: yesNordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

open access: yesOikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...

Trapped in the web: network architectures spread coevolution and shape adaptation

open access: yesOikos, EarlyView.
Adaptation is critical for biodiversity to persist under global change. Within ecological communities, species often face tradeoffs between adapting to shifting abiotic conditions and navigating the complex selective pressures imposed by interaction networks.
