Induced‐Fit Recognition by a Calixarene–Pyrene Conjugate for Single‐ and Dual‐Wavelength Fluorescence Sensing in Water

Chemistry – A European Journal, EarlyView.
A sulfonatocalix[4]arene–pyrene conjugate functions as a fluorescence chemosensor for the optical detection of biorelevant analytes in water. Its photoinduced electron transfer (PET) response is triggered by an induced‐fit recognition mechanism. Noncovalent assembly with an additional dye affords dual‐color ratiometric signaling via competitive PET ...

Dual‐State Photophysical Modulation via Bifurcated Hydrogen Bonding in a U‐Shaped Dipyridophenazine‐Cored Donor‐π‐Acceptor‐π‐Donor Fluorophore

Chemistry – A European Journal, EarlyView.
A donor–π–acceptor–π–donor (D–π–A–π–D) fluorophore bearing a U‐shaped dipyridophenazine core forms bifurcated hydrogen bonds with neutral donors such as sulfonamides or water. This interaction modulates both ground and excited states, enabling red‐shifted emission and enhanced photoluminescence in solution and solid state.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

Contributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

Deep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Twenty‐Minute Microwave‐Enabled Dual‐Anion Nickel Sulfoselenide Anodes for High‐Capacity Sodium/Potassium‐Ion Batteries and Durable Pouch Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐anion‐assisted strategy is proposed for designing bi‐functional high‐performance anodes. The preparation of NiSSe/N‐C within 20 min demonstrates rapid Na+/K+ reaction kinetics, exceptional rate capability, and remarkable cycling stability. Nickel‐based materials are promising anode candidates for sodium‐ion batteries and potassium‐ion batteries ...
