THE DETERMINATION OF FLUORIDE IN PLUTONIUM FLUORIDES

open access: yes, 1957
The Willard-Winter distillation was adapted to the determination of fluoride in plutonium fiuorides. Fluoride was distilled from samples in 12M sulfuric acid, and the distillate was then titrated to a visual end point with a standard solution of thorium nitrate.

Microscale Tin–Bismuth Alloy Prepared via Cooling Rate Control as Anode Material for High‐Performance Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
To investigate the mechanisms about the enhanced buffering effect and morphological retention in fully lithiated Sn–Bi alloys, this study introduces a new bulk bimetallic Sn–Bi alloy with fine grains of uniformly distributed Sn and Bi alloys (≈50 nm) via cooling rate control. This design effectively relieves internal energy buildup and suppresses crack

Ultrastable Perovskite Encased in a Helical Cage for Tunable Full‐Color Mirror‐Image Circularly Polarized Luminescence

open access: yesAdvanced Functional Materials, EarlyView.
Develop full‐color colloidal perovskite nanocrystal (PNC) composites using a single organic halide precursor and enhance their stability and emission through zirconium hydrogen phosphate nanosheets (NSs). Achieve high photoluminescence efficiency and dual‐state circularly polarized luminescence (CPL) by embedding stabilized PNCs into a chiral polymer ...

Curved Nanographene–Graphite Hybrid Anodes with Sequential Li+ Insertion for Fast‐Charging and Long‐Life Li‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A hybrid anode composed of Cl‐functionalized curved nanographene and graphite enables ultra‐fast charging and long cycle life through an engineered morphology and sequential Li+ insertion. It delivers 100 mAh g−1 at 5 C with 70% capacity retention after 1000 cycles and maintains stable performance over 2000 cycles in pouch cells, providing a practical ...
