PEDOT‐Based Eutectogel Electrode Arrays for Enhanced High‐Resolution Electrogastrography: Fabrication, Stability, and Wearable Performance

open access: yesAdvanced Functional Materials, EarlyView.
Here, we present a high‐density PEDOT eutectogel electrode array for enhanced body surface gastric mapping. Silver electrodes are blade‐coated onto flexible substrates, followed by electrogelation of PEDOT:PSS and the deposition of a PEDOT:LS eutectogel.

Teacher Quality and Educational Production in Secondary School [PDF]

open access: yes
This study uses administrative data linking students and teachers at the classroom level to evaluate teacher quality and joint production in secondary school. Teacher quality is measured by value-added to student test scores in math and reading. Although

A review of teacher evaluation beliefs [PDF]

open access: yes, 2012
Teacher evaluation beliefs have received a substantial amount of attention in the educational literature, but comparatively little attention from the belief research topics specially. As the driving force, evaluation resembles belief mention but lack the

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation

open access: yesAdvanced Functional Materials, EarlyView.
Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

Kinetic Regimes of Hydrogen Absorption in Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Knowledge of the hydrogen incorporation mechanisms in thin layers in relation to the amount absorbed is essential to design coatings and devices compatible with hydrogen‐based technologies. A combination of simultaneous in situ methods gives detailed insight into the hydrogenation of a prototypical hydrogen absorber layer in a time‐dependent manner ...

Evaluation of usage patterns for web-based educational systems using web mining [PDF]

open access: yes, 2001
Virtual courses often separate teacher and student physically from one another, resulting in less direct feedback. The evaluation of virtual courses and other computer-supported educational systems is therefore of major importance in order to monitor ...

Unlocking Photodetection Mode Switching from a Simple Lateral Design

open access: yesAdvanced Functional Materials, EarlyView.
A simple lateral 2D perovskite photodetector capable of switching among transient, continuous, and dual transient/continuous photoresponse modes is achieved by integrating photoconductive effects with capacitive coupling from the SiO2/Si substrate. Such light‐programmable photodetection mode switching enables triple‐channel information transmission and

Developing the scales on evaluation beliefs of student teachers [PDF]

open access: yes, 2009
The purpose of the study reported in this paper was to investigate the validity and the reliability of a newly developed questionnaire named ‘Teacher Evaluation Beliefs’ (TEB). The framework for developing items was provided by the two models.
