Electrochemical Doping for Absorption and Conductivity Tuning of P(NDI2OD‐T2) Films

open access: yesAdvanced Electronic Materials, EarlyView.
Electrochemical doping of P(NDI2OD‐T2) films allows for tuning the degree of doping both in liquid electrolytes as well as in the solid state. The nature of the doped species is elucidated by UV–vis spectroscopy and accompanying DFT calculations. Correlations between maximum conductivities and the presence of mixed valence states, (specifically neutral/

Solvated PbI2 Clusters Preceding the Crystallization of Lead Halide Perovskites–a UV/VIS In Situ Study

open access: yesAdvanced Electronic Materials, EarlyView.
This work focuses on the crystallization dynamics in lead iodide perovskite films: In situ UV absorption spectroscopy reveals a PbI2‐DMF solvated (PDS) phase before nucleation, influencing perovskite formation. PDS clusters act as nucleation seeds, linking precursor solution concentration to crystallization.

Conjugated Polymer Nanoparticles for Biophotonic Applications: Preparation, Characterization, and Simulation in Biohybrid Interfaces

open access: yesAdvanced Electronic Materials, EarlyView.
Conjugated polymer nanoparticles (CP‐NPs), namely P3HT‐, PCBM‐, and P3HT:PCBM‐NPs are explored, from preparation to biophotonic applications. The obtained CP‐NPs exhibit visible absorption, red/near infra‐red (NIR) emission, and light‐induced photocurrent generation in physiological media, stable optoelectronic behavior and size uniformity. Simulations

Weakly Solvating Electrolytes for Lithium and Post‐Lithium Rechargeable Batteries: Progress and Outlook

open access: yesAdvanced Energy Materials, EarlyView.
Weakly solvating electrolytes (WSEs) use anion‐dominated solvation to form stable interphase layers, overcoming energy density and lifespan limitations. This review clarifies their design, anion‐mediated interface regulation, and compatibility with lithium/post‐lithium systems, distinguishing them from conventional electrolytes, high concentration ...

Protective and Collision‐Sensitive Gel‐Skin: Visco‐Elastomeric Polyvinyl Chloride Gel Rapidly Detects Robot Collision by Breaking Electrical Charge Accumulation Stability

open access: yesAdvanced Intelligent Systems, EarlyView.
For safe human–robot collaboration (HRC), a protective and collision‐sensitive robot skin is proposed. The developed robot skin, named Gel‐Skin, is composed of polyvinyl chloride (PVC) gel, which is a functional material with impact absorption capability and tunable piezoresistive characteristics based on electrical charge‐accumulation.
