Single‐Step Electrochemical Battery Recycling

Advanced Functional Materials, EarlyView.
This work demonstrates the use of single‐step recovery, an electrochemical process combining electrodeposition and electro‐dissolution, to recover lithiated transition metal oxides (LTMOs). The batteries produced through this recycling method perform similarly to batteries made from pristine materials.

EFFECTIVE TEMPERATURE AND RADIAL VELOCITY OF THE SMALL AMPLITUDE CEPHEID POLARIS (alpha UMi) IN 2015

Odessa Astronomical Publications, 2016
We present the results of an analysis of 21 spectra of alpha UMi (Polaris) obtained in September – December 2015. Frequency analysis shows an increase of the pulsation period up to 8.6 min in comparison to the 2007 observational set.

Revisiting the theoretical DBV (V777 Her) instability strip: The MLT theory of convection [PDF]

, 2008
We reexamine the theoretical instability domain of pulsating DB white dwarfs (DBV or V777 Her variables). We performed an extensive g-mode nonadiabatic pulsation analysis of DB evolutionary models considering a wide range of stellar masses, for which the

Sensing of Chloride Ions in Sweat by Means of Printed Extended‐Gate Organic Electrochemical Transistors

Advanced Functional Materials, EarlyView.
In this work, a platform based on an Extended‐Gate OECT is successfully developed and tailored for the detection of physiologically relevant chloride ion concentrations in artificial eccrine sweat. Leveraging the extended‐gate architecture, a high‐performance OECT based on inkjet‐printed pg2T‐TT is coupled with an inkjet‐printed Ag/AgCl electrode ...

Hydroxylated Ionic Liquids as Functional Additives for Stable Aqueous Zn Batteries

Advanced Functional Materials, EarlyView.
A hydroxyl‐functionalized ionic liquid additive (HO‐EMImTfO) regulates Zn2+ solvation and electrodeposition by forming a stable ion‐diversion dam at the Zn interface. This design mitigates Zn pulverization, suppresses dendrite growth, and reduces side reactions, enabling Zn||Cu and Zn||V2O5 cells to achieve exceptional cycling stability and efficiency.

Side Reaction Pathway Modulation for Hydrogen Evolution‐Free Aqueous Zn‐Ion Batteries

Advanced Functional Materials, EarlyView.
A ZnO–TeO2–Te ternary composite layer with a unique rice grain‐like morphology is spontaneously formed on the Zn anode via telluric acid additive. This functional interphase effectively suppresses side reactions such as zinc hydroxide sulfate formation, hydrogen evolution, and Zn corrosion, enabling highly reversible and stable Zn metal cycling in ...
