Uncovering the Origin of Efficiency Roll‐Off in TADF OLEDs

Advanced Functional Materials, EarlyView.
OLEDs based on thermally activated delayed fluorescent (TADF) materials often suffer from a severe drop in efficiency at high brightness levels. This work presents a technique to uncover the source of this efficiency drop, and quantifies the exciton‐exciton and exciton‐polaron annihilation processes responsible for efficiency losses in our TADF OLEDs ...

Critical roles of short‐range‐order minerals in shaping soil water retention curves in volcanic regions

Vadose Zone Journal
Predicting water retention is difficult for highly aggregated volcanic soils (Andisols) with heterogeneous pore size distribution. This paper aimed to examine how andic materials influence soil water retention based on soil composition.

Effects of land-use change on morphological, physicochemical, and mineralogical properties of volcanic soils in southern Chile

Geoderma
Chilean volcanic soils, such as Andisols and Ultisols, cover much of the country’s arable land and are valued for their unique mineralogical characteristics.

Halide‐Dependent Photoluminescence and Heavy‐Atom Effects in Low‐Melting Organic–Inorganic Manganese Halides

Advanced Functional Materials, EarlyView.
Two pyridinium‐based ionic liquid templated hybrid manganese halides, (C4Py)2[MnCl4] and (C4Py)2[MnBr4], display similar bulk structures but show significantly different photoluminescence behaviors due to the bromine heavy‐atom effect. Their stable local Mn environments remain intact even in the molten state, allowing applications such as luminescence ...

Andic soils and catastrophic mudflows in Italy: morphological and hydropedological evidences [PDF]

, 2010
In Italy rapid landslides are the most frequently occurring natural disasters and, after earthquakes, cause the highest number of victims. In this contribution we attempt to prove that there exist a tight connection between the presence of a specific ...

Relationships between land use, fertility and andisol behaviour : examples from volcanic islands [PDF]

, 1999
Soils developed on voIcanic parent materials have many intrinsic qualities favourable to cropping. Howerer, fertility decreases dramatically when they are badly managed.

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

Advanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

Propagation of High Frequency Waves in the Quiet Solar Atmosphere

, 2008
High-frequency waves (5 mHz to 20mHz) have previously been suggested as a source of energy accounting partial heating of the quiet solar atmosphere. The dynamics of previously detected high-frequency waves is analysed here.

ETV2 Mediated Differentiation of Human Pluripotent Stem Cells Results in Functional Endothelial Cells for Engineering Advanced Vascularized Microphysiological Models

Advanced Healthcare Materials, EarlyView.
A robust method to generate functional human iPSC‐derived endothelial cells using inducible ETV2 expression. These cells self‐organize into stable, lumenized microvascular networks within microfluidic chips, surpassing conventional differentiation methods.

Preliminary results of a network of trials related to sugarcane nutrition in Reunion Island [PDF]

, 2010
IN REUNION ISLAND, sugarcane is grown under highly contrasting climatic conditions, from the sea level to the highlands (up to 1000 m altitude), with very different soil types.
