Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

The Elasticity-Based Approach to Enterprise Innovation

open access: yesInternational Journal of Management and Economics, 2016
The goal of this paper is to present a formal model of firm innovation that simultaneously analyzes innovation factors characteristic to the Schumpeterian strand of industrial organization literature and the know-how strand.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

open access: yesAdvanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Functional categories in the L2 acquisition of English Morpho-syntax: a longitudinal study of two Farsi-speaking children [PDF]

open access: yes, 2007
This is a longitudinal case study of two Farsi-speaking children learning English: 'Bernard' and 'Melissa', who were 7;4 and 8;4 at the start of data collection.

Processing empty categories in a second language: When naturalistic exposure fills the (intermediate) gap [PDF]

open access: yes, 2013
An ongoing debate on second language (L2) processing revolves around whether or not L2 learners process syntactic information similarly to monolinguals (L1), and what factors lead to a native-like processing. According to the Shallow Structure Hypothesis

Tailoring Symmetry Breaking in Engineered van der Waals Superlattices

open access: yesAdvanced Materials, EarlyView.
We pioneer a scheme to tailor superpotentials in graphene based on intrinsic substrate electronic orders rather than twist angle. The resulting superpotential folds graphene's Dirac cones to either Γ$\Gamma$ or K‐points, leading to distinct symmetry behaviors.

Side‐Chain‐Induced Interlayer Slipping in Metalloporphyrin COFs Enables Microenvironment and Spin‐State Regulation for Photocatalytic CO2 Reduction

open access: yesAdvanced Materials, EarlyView.
Alkoxy chain length drives a continuous transition from eclipsed AA to a serrated, slipped AA* configuration over Co‐porphyrin COFs. A moderate slip both contracts the pore channel to enrich CO2 and suppress hydrogen evolution, and enhances collective high‐spin of Co sites, which delivers a record CO production rate with high selectivity.

The L2 acquisition of agreement: comparing the inter language of Dutch, English, French and Swedish-speaking learners of Spanish [PDF]

open access: yes, 2007
Much of current generative research into non-native language (L2) acquisition of morphosyntax has focused on L1 transfer and access to Universal Grammar.

Bifunctional Catalysis Drives Efficient and Ethanol‐Producing Aqueous Zn‐CO2 Batteries

open access: yesAdvanced Materials, EarlyView.
A unified bifunctional catalyst breaks the trade‐off between CO2 reduction and O2 evolution, delivering high efficiency, ethanol production, and long‐term stability in Zn‐CO2 batteries while revealing degradation pathways for next‐generation bifunctional electrocatalysts.

The Acquisition of Case in Spanish Pronominal Object Clitics in English-Speaking College-Level L2 Learners [PDF]

open access: yes, 2013
The Second language acquisition (SLA) of Spanish pronominal object clitics (POCs) has been a topic of research with regards to clitic placement (Houston, 1997; Lee, 1987; LoCoco, 1987; VanPatten, 1984; and VanPatten & Houston 1998), acquiring specific ...
