Tailoring Symmetry Breaking in Engineered van der Waals Superlattices

Advanced 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.

N-Drop and Determiners in Native and Non-Native Spanish: More on the Role of Morphology in the Acquisition of Syntactic Knowledge

Círculo de Lingüística Aplicada a la Comunicación, 2023
In order to investigate whether the acquisition of N-drop (null nouns) is related to the acquisition of the agreement system of Spanish determiners this paper analyzes L1 longitudinal Spanish data from two children and L2 longitudinal data from two ...

Ambient‐Spray Ni–Cu(–O)/Ag Nanowire Transparent Heaters for High‐Temperature Heating and Far‐/Near‐Field EMI Suppression

Advanced Materials Interfaces, EarlyView.
A vacuum‐free, ambient‐spray Ni–Cu(–O)/Ag nanowire transparent‐heater platform is realized via conformal junction‐shell engineering and silica–hybrid overcoating, enabling robust high‐temperature heating together with GHz‐band far‐field EMI shielding and near‐field magnetic‐noise attenuation.

Pronunciation learning environment: EFL students’ cognitions of in-class and out-of-class factors affecting pronunciation acquisition

Theory and Practice of Second Language Acquisition, 2018
The way a foreign language (L2) learner perceives his or her educational environment may affect their processes of L2 acquisition. The aim of the study presented in this paper is to explore English as a foreign language (EFL) students’ cognitions of ...

Cation‐π Interaction‐Based Biointerface for Low‐Cost PD‐1 Detection Toward NSCLC Immunotherapy Monitoring

Advanced Materials Interfaces, EarlyView.
A cation‐π interaction‐based biointerface is engineered on a CNT‐FET for label‐free detection of PD‐1. PD‐1 monoclonal antibodies are orientedly immobilized via cation‐π interactions between PCz‐wrapped semiconducting single‐walled carbon nanotubes and the Fc region of the monoclonal antibody.

Passive Directional Water Transport on Superhydrophobic Gradient Textures Fabricated by Direct Laser Interference Patterning

Advanced Materials Technologies, EarlyView.
Microstructures fabricated by two‐beam DLIP combining spatial‐period and roughness gradients are fabricated to enhance directional transport of water droplets. The coupled gradients increase transport distance by 160% and strongly suppress motion against the gradient, demonstrating an effective strategy for controlled droplet manipulation.

Two‐Dimensional Isotropic Spatial Differentiation Through Complete Polarization Control

Advanced Optical Materials, EarlyView.
This work enables two‐dimensional isotropic spatial differentiation at planar interfaces over a wide range of incident angles by extending the output polarization from linear to elliptical. The choice of incident angle can be used to balance broader spectral response at low angles and higher edge‐detection efficiency at larger angles.
