Strong Tough Hydrogel with Regional Programmable Mechanical Properties via Universal Physical Directional Anneal‐Casting Strategy for Bioengineering

Small Structures, EarlyView.
A new and universal directional anneal‐casting (DAC) strategy is presented to produce strong tough hydrogels with biomimetic hierarchical anisotropic structure by modulating water evaporation. Target hydrogels can be precisely and comprehensively controlled to mimic a broad range of mechanical properties and water contents characteristic of various ...

Structural behavior of deteriorated Gerber half‐joints in highway overpasses by nonlinear finite element analysis combined with a simplified uniform‐corrosion model

Structural Concrete, EarlyView.
Abstract Gerber half‐joints, broadly used in the last century as elements of concrete bridges, are prone to corrosion‐induced deterioration, which may lead to brittle shear collapse. It is of paramount importance to develop advanced numerical models for simulating the collapse behavior of Gerber half‐joints, taking material deterioration into account ...

‘It's like English is given more emphasis than the topic’: Designing materials in English language teacher education

TESOL Quarterly, EarlyView.
Abstract Despite decades of curricular change and the introduction of language pedagogies emphasising meaning and communication, teachers of English in Chilean schools still tend to favour traditional methods and focus largely on discrete language. Using data from stimulated recalls, interviews and observations with preservice teachers, interviews with
