Super-radiance reveals infinite-range dipole interactions through a nanofiber
Nature Communications, 2017 The confinement of electromagnetic field in one dimension is known to allow peculiar effects such as infinite-range coupling. Here, the authors report on the observation of light-mediated infinite-range interactions between spatially separated atomic ...

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,

A close-up view of coarse limestone from New Bern, North Carolina, set in the NIST stone wall
, 2017 The NIST stone wall was built using 2,352 stones from 47 US states and 320 from 16 foreign countries. The wall is approximately 12 m long, 4 m high, 0.6 m thick at the bottom, and 0.3 m at the top. The aim of the wall construction was to study the aging

Advanced Physics Research, EarlyView.This study explores the use of single‐walled carbon nanotubes (SWCNTs) for thermoelectric (TE) applications to convert waste heat into electricity. By examining two SWCNT types with varying purity, structure, and thickness, it assesses how different solvents used in buckypaper fabrication affect their TE properties.

Investigation of Electrolyte Salts in Non‐Flammable Triethyl Phosphate for Sodium‐Ion Batteries
Batteries &Supercaps, Volume 8, Issue 3, March 2025.This study evaluates five sodium electrolyte salts (NaBF₄, NaClO₄, NaDFOB, NaFSI, NaPF₆) in triethyl phosphate (TEP) for sodium‐ion full‐cells, focusing on their physicochemical properties, solvation structure, and electrochemical performance. The addition of 1 wt.% vinylene carbonate (VC) improves cycling performance, with NaFSI demonstrating 88 ...
