Precise Microstructural and Stoichiometric Control Advances Flexible Ag2Te Thin‐Film Thermoelectrics for Wearable Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Flexible Ag2Te thin films achieving a record‐high mobility of 4756 cm2 V−1 s−1 and a peak power factor of 18.5 µW cm−1 K−2 are developed via precise structural control. The assembled flexible devices demonstrate excellent mechanical stability and ultrafast voltage response, enabling precise thermal detection when integrated into a robotic gripper for ...

LA VOLEUSE D´ENFANTS D´ERCKMANN-CHSTRIAN: MONSTRE NARRATIF OU CONTE CRUEL?

open access: yesAnales de Filología Francesa, 2006
La Voleuse d’enfants, recogida en los Contes des Bords du Rhin, es una nouvelle muy curiosa. Se distingue de los otros relatos cortos de Erckmann- Chatrian por la crueldad de su tema y por el tratamiento narrativo. Difícil de encerrar en un único género,

Impact of Oxygen Plasma Pre‐Treatment on Thermal Oxidation and Reliability of SiO2 on 4H‐SiC

open access: yesAdvanced Materials Interfaces, EarlyView.
We investigate how oxygen plasma pre‐treatment affects the thermal oxidation of silicon carbide. While plasma modification increases growth rates by 84%, it reduces dielectric breakdown strength by 18%. Our findings reveal that although plasma improves the interface state density, it introduces structural damage, highlighting a critical trade‐off ...

Estableciendo diálogos entre diferentes marcos teóricos: de los procesos narrativos a la teoría antropológica de lo didáctico [PDF]

open access: yes, 2010
El punto de partida de este artículo es el fenómeno de la co-existencia de diferentes marcos teóricos en didáctica de las matemáticas. Proponemos reformular este fenómeno en términos de un problema científico: el problema del establecimiento de diálogos ...

Energy Band Alignment and Electro‐Optical Behavior of Nearly Unstrained Monolayer MoS2 Heterostructures With GaN

open access: yesAdvanced Materials Interfaces, EarlyView.
Large size (∼100 µm) monolayer MoS2 grown by LPI‐CVD on n‐GaN exhibit a high n‐type doping, very low strain, and a type‐I band alignment at MoS2/GaN interface. Photocurrent measurements under illumination with photon energies from ∼2 to ∼5 eV show superior electro‐optical performances of these MoS2/n‐GaN heterojunctions as compared to Ni/n‐GaN devices ...

A Simplified Calculation Method of Length Adjustment of Datum Strand for the Main Cable with Small Sag

open access: yesAdvances in Civil Engineering, 2019
In order to overcome the complicated iterative process of the cable length adjustment based on catenary theory and large error of length adjustment for cable with a small sag based on the parabola theory, this paper firstly develops a direct and simply ...

LFA: A Lattice Fourier Analyzer for Quantitative In Situ EC‐STM of Adsorbate–Substrate Superstructures

open access: yesAdvanced Materials Interfaces, EarlyView.
Although electrochemical scanning tunneling microscopy provides atomic‐scale access to electrified interfaces, quantitative in situ and operando investigations suffer from drift‐induced distortions. This work introduces the Lattice Fourier Analyzer (LFA), which employs substrate‐anchored affine drift correction in reciprocal space to recover precise ...

Deformación y reflexión de funciones con GeoGebra. El caso de las parábolas definidas por la expresión g(x)=a.x^2 [PDF]

open access: yes, 2015
En este trabajo describimos una secuencia para caracterizar las transformaciones “deformación” y “reflexión” en familias de parábolas definidas por g(x)=a.x^2,utilizando el GeoGebra.

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance

open access: yesAdvanced Materials Interfaces, EarlyView.
Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.

Anti‐Slip Material‐Based Strategies and Approaches

open access: yesAdvanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.
