Color‐Tunable Glass for Adaptable Thermal Management Based on Silver Phase Change

open access: yesAdvanced Science, EarlyView.
This article presents an Ag particle‐based thermal management device achieving both selective visible reflection and effective heat flux control. Morphological changes of silver during annealing enable tunable color and thermal regulation via a simple fabrication process.

Thermal Control of Vortex Motion in Nanoscale Superconductors

open access: yesAdvanced Electronic Materials, EarlyView.
Vortices in superconducting film can be thermally steered by a local heating from a tip. The work shows that the vortex is attracted by the hot spot by a force that emulates an electric field resulting in a fictious Lorentz‐force on the vortex. Abstract Thermally induced motion of vortices in nanoscale superconductors (SCs) is investigated.

Alternative Solid‐State Synthesis Route for Highly Fluorinated Disordered Rock‐Salt Cathode Materials for High‐Energy Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work presents a tailored solid‐state route to enhance DRX fluorination and electrochemical performance. Using unconventional precursors, Li6MnO4, MnF2, and TiO2, prevents Mn‐based intermediates, which do not accommodate fluorines, enabling the formation of highly fluorinated DRX with a composition of Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34 ...

A Novel Quantification Method for High Voltage Structural Evolution in Sodium and Lithium Layered Oxides

open access: yesAdvanced Energy Materials, EarlyView.
High‐voltage cycling of layered alkali transition metal oxides in Li‐ and Na‐ion cells increases energy density but diminishes lifetime. A novel XRD‐analysis method, centered on the stacking factor “z”, is developed to quantify the stacking fractions in the OP hybrid structure.

Nanoarchitectonics of N‐ and S‐Doped Nanoporous Biocarbons with High Specific Surface Area from Casein and Dithiooxamide for Supercapacitor Applications

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
N, S codoped nanoporous biocarbons are synthesized using casein and dithiooxamide via a low‐cost chemical activation approach. Reasonable high surface areas and concentrations of codopants were observed. This leads to a good capacitance of 178 F g−1 along with good cycling stability of 93.2% retention after 300 cycles, which demonstrates the ...

Fluoride Enhances Alcohol Binding Within a Trigonal‐Prismatic Metal‐Organic Capsule

open access: yesAngewandte Chemie, EarlyView.
Steric hindrance from methyl groups orients rectangular ligands “landscape”‐wise, forming a trigonal prismatic capsule with a large cavity. Endohedral functionalization of this capsule via fluoride binding tunes its guest affinity, enhancing the binding of alcohols over ketones and enabling selective perrhenate encapsulation and release, offering an ...
