Miocene to Quaternary Tectonostratigraphic Evolution of the Northern Section of the Burdur‐Fethiye Shear Zone, South‐Western Türkiye

Geological Journal, EarlyView.
New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

Journal of Quaternary Science, EarlyView.
ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate change.

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

Laser &Photonics Reviews, EarlyView.
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...

Impact of Monomer Purity on the Acid‐Catalyzed ROP of Sarcosine N‐Carboxyanhydrides: A Comparative Study of Phosgene‐Free Synthetic Routes toward High‐Molecular‐Weight Polysarcosine

Macromolecular Rapid Communications, EarlyView.
A robust, phosgene‐free oxalyl chloride/silyl‐mediated route yields high‐purity sarcosine N‐carboxyanhydride (Sar‐NCA) by eliminating residual impurities that compromise polymerization control. This strategy enables well‐defined, acid‐catalyzed ring‐opening polymerization under ambient conditions, producing polysarcosine with Mn up to 186 kDa and ...

Serum elemental profile‐based machine learning models for Alzheimer's disease identification and cognitive score prediction

Neuroprotection, EarlyView.
Serum elemental profiling combined with machine learning supports exploratory Alzheimer's disease (AD) identification and cognitive score prediction. In this retrospective cross‐sectional study, 874 participants from the BANC‐PUMC, including cognitively normal controls and patients with AD, were analyzed.

Suitability of slightly saline irrigation for alleviating drought stress in taro and yam in Tonga: Implications for climate‐resilient Pacific cropping systems

PLANTS, PEOPLE, PLANET, EarlyView.
There is an increasing risk of drought and salinisation of soil and groundwater globally, including in Pacific Island countries such as Tonga. Irrigating crops with slightly saline water, such as that produced by emerging desalination technologies, could help to alleviate droughts.

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Tumor microenvironment responsive and nanozyme‐catalyzed photodynamic therapy via lysosome‐localized copper‐doped carbon dots

Responsive Materials, EarlyView.
The lysosome‐localized copper‐doped carbon dots (Cu‐MLCDs) leverage the high expression of glutathione (GSH)/H2O2 in the tumor microenvironment to achieve fluorescence reactivation enhancement. Through its multi‐nanozyme activities (glutathione peroxidase, peroxidase, and catalase), this nanoplatform relieves hypoxia, depletes GSH, and synergistically ...

Silver‐Modulated Copper Dynamics Under Pulsed Tandem Electrochemical CO2 Reduction

Small, EarlyView.
Under pulsed CO2 reduction, Ag does more than provide CO for tandem catalysis. It redirects how Cu dissolves, redeposits, and remains catalytically relevant, generating an Ag‐rich yet Cu‐active working state. Correlative surface and solution analysis reveal that tandem performance emerges from dynamic material redistribution rather than from a static ...

Tailoring Zn2+ Solvation for Dendrite‐Free and High‐Efficiency Aqueous Zinc Batteries

Small, EarlyView.
A ternary water–methanol–dimethyl sulfoxide hybrid electrolyte reconstructs the Zn2+ solvation sheath by reducing free water activity and promoting coordinated solvent interactions. The regulated interfacial chemistry suppresses parasitic reactions and enables dense, uniform zinc deposition, resulting in enhanced reversibility and long‐term cycling ...
