Spatiospectral Photoacoustic Microscopy With Gain‐Switched Ti:Sapphire Laser for High‐Accuracy Molecular Dynamics Imaging

Laser &Photonics Reviews, EarlyView.
Spatiospectral photoacoustic microscopy is enabled by stable, wavelength‐tunable dual‐pulse excitation from a gain‐switched Ti:sapphire laser. Intrinsically synchronized 532‐nm and NIR‐I pulses provide single‐scan, co‐registered mapping of oxygen saturation and indocyanine green dynamics in vivo.

Interaction With Surface Spins as a Contribution to Nuclear Magnetic Relaxation of Liquids Adsorbed in Mesoporous Materials

Magnetic Resonance in Chemistry, EarlyView.
Liquids at silica interfaces experience demixing as a consequence of their respective polarity. The distribution of liquids and their primary relaxation contributions are studied by surface modification with OD and radical moieties, respectively. ABSTRACT NMR relaxation of liquids in the presence of solid interfaces, such as silica gel or porous glass,

A novel n‐type dimer dopant for semiconducting polymers

Polymer International, EarlyView.
A novel molecular n‐type dopant (1) with superior capacity to dope conjugated polymers is introduced. After charge transfer the product (2) remains in the polymer. Abstract Efficient and stable doping of organic semiconductors is crucial for adjusting their electrical properties.

Upgrade des CMS‐Detektors für die Hochratenphase des LHC: Die Runderneuerung von CMS

Physik in unserer Zeit, EarlyView.
Ab 2030 wird der LHC in der Hochratenphase laufen. Die erheblich gesteigerte Proton‐Proton‐Kollisionsrate erfordert ein grundlegendes Update der beiden großen Detektoren ATLAS und CMS, dessen Runderneuerung hier vorgestellt wird. Zusammenfassung Ab 2030 soll der Large Hadron Collider (LHC) am CERN in der Hochratenphase (High Luminosity, High‐Lumi ...

Strukturaufklärung mittels Nanoplasmen: Wenn Nanocluster explodieren

Physik in unserer Zeit, EarlyView.
Lasererzeugte Nanoplasmen sind mikroskopische Labore für extreme Materiezustände. Der Zerfall dieses äußerst instabilen Zustands in einer Coulomb‐Explosion manifestiert sich in schnellen Elektronen, hochgeladenen Ionen und kurzwelliger Strahlung. Ihre Analyse offenbart Einblicke in die hochdynamischen Prozesse der Ionisation und Relaxation.

Reservoir‐Computer auf Basis von Magnonen: Maschinelles Lernen im reziproken Raum

Physik in unserer Zeit, EarlyView.
Künstliche Intelligenz droht, einer der größten Energieverbraucher der Menschheit zu werden. Der Grund liegt in der geringen Effizienz der herkömmlichen Halbleitertechnologie. Abhilfe versprechen radikal neue Konzepte. An einem solchen Konzept forschen wir: Ein sogenannter Reservoir‐Computer, der Magnonen, also Spinwellen, nutzt.

In Situ Atomic‐Scale Observation of Preferential Premelting at Oxide Crystal Defects

Small, EarlyView.
Under an external stimulus (e.g., an electron beam irradiation), premelting preferentially initiates at the planar defects in crystalline materials, thereby altering the local atomic and electronic structures. [Correction added on July 21, 2026, after first online publication: The graphical abstract figure has been updated.] ABSTRACT Under certain ...
