Determination of Barium in Uranium Compounds by Conductometric Titration

open access: yesCroatica Chemica Acta, 1964
A method for the determination of barium by conductometric titrn.tion in the precipitates of the system uranyl nitrate -potassium hydroxide - barium nitrate, is proposed. The precipitates were dissolved in concentrated nitric acid and uranium separated by means of continuous extraction with tetrahydropyrane. Barium could be determined from 0,.6 to 7 mg

A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans

open access: yesAdvanced Science, EarlyView.
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

open access: yesAdvanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...
