Hollowing Out Nanofibers for Enhanced Visual Brightness and More Effective Solar Heating

Small, EarlyView.
A solar‐heating mat of hollow nanofibers can be brighter yet hotter than its paired solid counterpart at suitable fiber dimensions. The hollow nanofibers enhance visible backscattering and suppress heat dissipation. Indoor and outdoor side‐by‐side tests show higher solar‐heating temperatures for the hollow mat, demonstrating hollowing as a structural ...

Odd‐even effects in molecular junctions: A Solomonic resolution of conflicting reports on conductance trends, metal specificity, and microscopic origin

Smart Molecules, EarlyView.
By combining extensive transport data with the off‐resonant single‐level model and z‐score statistics, we demonstrate that the odd–even alternation is platform‐independent, of dual interface–bulk origin, and exhibits a conductance crossover at n = 12—reconciling contradictory literature and providing a Solomonic solution to debates on trends, metal ...

The relationship between VHF radar auroral backscatter amplitude and Doppler velocity: a statistical study

Annales Geophysicae
A statistical investigation of the relationship between VHF radar auroral backscatter intensity and Doppler velocity has been undertaken with data collected from 8 years operation of the Wick site of the Sweden And Britain Radar-auroral Experiment (SABRE)

Contact‐Free Mechanical Mapping of 3D Microprinted Hydrogels Using FLIM

Small Methods, EarlyView.
A fluorescence lifetime imaging microscopy (FLIM)‐based approach is presented that exploits the intrinsic autofluorescence of two‐photon 3D laser printed hydrogel microstructures for contact‐ and label‐free mechanical mapping. Autofluorescence lifetimes of 3D printed micropillars correlate with the degree of acrylate conversion and stiffness and are ...

Resolving Real‐Time Interfacial Dynamics on Garnet‐Based Solid‐State Electrolytes via Snapshot Operando XPS

Small Methods, EarlyView.
This work establishes snapshot operando x‐ray photoelectron spectroscopy (XPS) as a compelling laboratory‐based technique for real‐time probing of dynamic interfaces in solid‐state batteries. By combining second‐scale temporal resolution with complementary HAXPES depth profiling, the methodology enables direct observation of electrochemical processes ...

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...
