Electric Field‐Dependent Conductivity as Probe for Charge Carrier Delocalization and Morphology in Organic Semiconductors

open access: yesAdvanced Functional Materials, EarlyView.
Applying a high electric field to a doped organic semiconductor heats up the charge carrier distribution beyond the lattice temperature, enhancing conductivity. It is shown that the associated effective temperature can be used to extract the effective localization length, which is a characteristic length scale of charge transport and provides ...

A Regional Investigation of Inverse Distance Weighting Particulate Matter Prediction within Kirkuk City, Iraq

open access: yesInternational Journal of Economic and Environment Geology
It is well known that air polluted with particulate matter (PM) has a negative impact on human health. It is important to monitor and evaluate air quality by revealing the nature of the air and identifying the areas affected by particles. The methods and

Organometallic Precursor‐Induced Gradient Architecture on Multilayer Nanoporous Graphene Membranes for Precise Organic Solvent Nanofiltration

open access: yesAdvanced Functional Materials, EarlyView.
Alumina growth narrows surface pores and seals non‐selective defects, enhancing selectivity while preserving the nanoporous graphene architecture. Additionally, the deposition enables gradient‐controlled structural modification, with intergrown alumina acting as a physical cross‐linker that stabilizes the laminar structure.

Geostatistical Analysis of the Permeability Coefficient in Different Soil Textures

open access: yesContemporary Agriculture, 2018
Estimating soil hydraulic properties are so important for hydrological modeling, designing irrigation-drainage systems and soil transmission of soluble salts and pollutants, although measurements of such parameters have been found costly and time ...

Overcoming Debye Length Limitations in Electrolyte‐Gated Transistor Biosensors Using Nanoscale‐Grooved Oxide Semiconductors Fabricated by Thermal Nanoimprint Lithography

open access: yesAdvanced Functional Materials, EarlyView.
Nanoscale‐grooved indium gallium oxide (IGO) semiconductors, patterned via thermal nanoimprint lithography (NIL) using CD/DVD templates, are integrated into electrolyte‐gated transistor biosensors to overcome Debye length limitations. Precisely engineered concave–convex nanostructures modulate local electrostatic potentials, extend the effective Debye ...

Banks in Space: Does Distance Really Affect Cross-Border Banking? [PDF]

open access: yes
During the last years, gravity equations have leapt from the trade literature over into the literature on financial markets. Martin and Rey (2004) were the first to provide a theoretical model for cross-border asset trade, yielding a structural gravity ...

Kernel Interpolation for Scalable Structured Gaussian Processes (KISS-GP) [PDF]

open access: yes, 2015
We introduce a new structured kernel interpolation (SKI) framework, which generalises and unifies inducing point methods for scalable Gaussian processes (GPs).

Two‐Way Shape Memory Alloy and Polymer Composite Hybrid Smart Actuator With High Speed, Accuracy, and Reversible Deformation

open access: yesAdvanced Functional Materials, EarlyView.
Tailored thermo‐mechanical properties of shape memory polymer composites enable large reversible deformation as well as high actuation speed. Moreover, a structural design with curvature in the transverse direction achieves sub‐second actuation on heating and a larger recovery ratio on cooling. Finally, these newly developed smart two‐way actuators can

s‐Orbital Mediated Metavalent Bonding Enables State‐Of‐The‐Art n‐Type AgBiSe2 Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
Metavalent bonding (MVB) underpins the exceptional property portfolio of chalcogenides. Typical MVB solids are mainly found in p‐bonded systems. This work reveals that MVB can also be formed with s‐p orbital interactions upon forming a single‐electron σ‐bond, as exemplified in AgBiSe2.

Specification tests of asset pricing models using excess returns [PDF]

open access: yes
We discuss the impact of different formulations of asset pricing models on the outcome of specification tests that are performed using excess returns. It is generally believed that when only excess returns are used for testing asset pricing models, the ...
