Construct Validation of Self-Determination Theory in Second Language Scale: The Bifactor Exploratory Structural Equation Modeling Approach

Frontiers in Psychology, 2021
The present study aimed to assess the construct validity of the Self-Determination Theory in Second Language Scale (SDT-L2; Alamer, 2021). The study involved 266 undergraduate students learning English as a second language (L2) in Saudi Arabia.

Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

Advanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

High‐Power Rapid Laser‐Induced Synthesis of Multi‐functional Cobalt Metal‐Organic Framework With an Unprecedented Synthesis Efficiency

Advanced Materials Technologies, EarlyView.
Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

Piezoresistivity Enhancement by Graphite Flake Alignment in Thin Composite Films for Dielectric Elastomer Switches

Advanced Robotics Research, EarlyView.
This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.

Mechanical Flexibility Enables DNA Origami to Overcome Steric Confinement in Mucus

Advanced Science, EarlyView.
Mechanical flexibility is introduced as a design parameter to enhance nanocarrier transport in mucus. Using DNA origami, flexibility is decoupled from size, shap and surface chemistry, revealing improved passage through confined hydrogel networks. While surface passivation reduces aggregation, flexibility further boosts transport, offering a general ...

Microstructural Characters of Lyctinae and Dinoderinae (Coleoptera: Bostrichidae)

Psyche: A Journal of Entomology, 2010
Thirty-three species belonging to the bostrichid subfamilies Lyctinae and Dinoderinae were examined by low vacuum ESEM without sputtering. Eight types of microsculpture, five types of hair insertion, and 14 types of hair were found on the elytral disc ...

Voltage‐Reconfigurable Magneto‐Ionic Nanolayers in Dot Arrays for Probabilistic, Materials‐Engineered Security Primitives

Advanced Science, EarlyView.
A magneto‐ionic security‐by‐materials‐design strategy exploits voltage‐driven N3– migration in selectively contacted FeCoN dots, creating reconfigurable sub‐15 nm ferromagnetic sublayers with deterministic and/or probabilistic (single‐domain↔vortex) states, voltage‐tunable probabilities and fully stochastic orientation/chirality.

Investigating the Applicability of Alignment—A Monte Carlo Simulation Study

Frontiers in Psychology, 2022
Traditional multiple-group confirmatory factor analysis (multiple-group CFA) is usually criticized for having too restrictive model assumption, namely the scalar measurement invariance.

In Situ Generation of a Robust Gel Polymer Electrolyte From a Poly(Ethylene Carbonate)‐Hydrogenated Nitrile Butadiene Rubber Containing Thermoplastic Vulcanizate Electrolyte

Journal of Applied Polymer Science, EarlyView.
A gel polymer electrolyte thermoplastic vulcanizate (GPE–TPV) was prepared by blending HNBR and PEC by melt extrusion then thermally decomposing PEC to yield liquid EC. EC is absorbed into the crosslinked HNBR, yielding an electrolyte that is mechanically and electrochemically stable enough to permit cycling in a LiFePO4–Li half‐cell.
