All‐Inorganic Cesium Zinc Halides as Ultra‐Stable Lead‐Free Perovskite Electrodes for Li‐Ion Batteries

open access: yesAdvanced Electronic Materials, EarlyView.
Here we explore the use of lead‐free metal halide perovskites in lithium ion batteries. Cesium zinc chloride and bromide both show reasonable discharge capacities and high stability compared to lead based perovskites. ABSTRACT Halide perovskites have recently gained attention for use as electrode materials in lithium‐ion batteries. However, lead halide

On daily interpolation of precipitation backed with secondary information [PDF]

open access: yes, 2010
This paper investigates the potential impact of secondary information on rainfall mapping applying Ordinary Kriging. Secondary information tested is a natural area indicator, which is a combination of topographic features and weather conditions.

Photoluminescence Turn‐On Method to Determine the Kinetics of Thermally Activated Delayed Fluorescence Materials

open access: yesAdvanced Physics Research, EarlyView.
Thermally Activated Delayed Fluorescence (TADF) is widely exploited to achieve high‐efficiency OLEDs. TADF Emitters are normally investigated with transient photoluminescence (PL), which requires the PL to be detected over multiple orders of magnitude in time and intensity.

Advancing Cave Survey Methods: High‐Precision Mapping in Drakotrypa Cave, Greece

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Cave floor mapping plays a vital role across various scientific disciplines by enabling the identification and interpretation of features shaped by both natural processes and human activity. In cave archaeology, floor mapping is crucial to decode and reconstruct human‐induced morphological features.

A trade‐off between efficiency and stability in a class of sky‐blue organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
OLED efficiency and stability are correlated with device structure using combined experimental and simulation approach. Efficient, but less stable devices suffer mainly from exciton‐exciton annihilation, while their opposites have excitons predominantly quenched by polarons.
