Multispectral Mid‐Infrared Imaging With Incoherent Light via Adiabatic Upconversion

Laser &Photonics Reviews, EarlyView.
We demonstrate room‐temperature broadband MIR imaging based on adiabatic frequency upconversion, driven by a Q‐switched pump laser and incoherent illumination. The small‐foot‐print system upconverts the spectral range to the visible domain, without scanning, thermal control and with spatial resolution below 20μm$20\mathrm{\mu}\mathrm{m}$.

Relevance of the Magnetic Nanoparticles for Second Harmonic Ultrasound Generation: A New Approach for Magneto‐Acoustic Theranostic

Small, EarlyView.
Pulsed electromagnetic fields induce second harmonic ultrasound generation in magnetic nanoparticles under isothermal conditions without heating. Non‐aligned and magnetically pre‐aligned nanoparticle clusters significantly enhance acoustic emission amplitude.

Making Water Investible: Development Banking, Regulatory Governance, and the Institutional Production of Sanitation Infrastructure in Brazil

Regulation &Governance, EarlyView.
ABSTRACT Why did long‐horizon private investment in Brazilian water and sanitation expand after 2016 despite fragmented authority and persistent political contestation? This article places the Brazilian Development Bank (BNDES) inside, rather than outside, the credible‐commitment framework. It argues that the bank operated as a credibility intermediary:

Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Computation‐Guided Control of Excited‐State Deactivation Through Modulation of Conical‐Intersection Accessibility by Donor–Acceptor Asymmetry in Bridged Stilbene AIE Luminogens

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Donor–acceptor asymmetry modulates conical‐intersection accessibility and topology in bridged stilbenes, providing mechanistic insight into excited‐state deactivation and aggregation‐induced emission (AIE). ABSTRACT A computation‐guided investigation of asymmetric donor–acceptor bridged stilbenes reveals structure–property relationships governing ...
