Designing Polymer Nanocomposites for X‐Ray Shielding: Mechanisms, Architectures, and Scalable Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This review highlights advances in lightweight, lead‐free polymer nanocomposites for diagnostic X‐ray shielding. By linking filler chemistry, dispersion, architecture, and photon interaction mechanisms, it establishes structure–performance relationships guiding material design.

A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

The growth of sun and shade leaves of Populus euramericana "robusta" in relation to age, light intensity and temperature

open access: yes, 1974
The growth and development of sun and shade leaves was investigated in Populus euramericana 'Robusta', growing under various light intensities and temperatures and on a substrate optimal for the roots.Strong correlations exist between the dimensions of ...

On the contribution of leaf surface wetness, leaf size and leaf longevity to variation in leaf water and carbon balance [PDF]

open access: yes, 2009
It is widely recognized that many aspects of plant form and function are coupled to variation in water availability. This is because plant persistence is ultimately dependent upon the process of carbon fixation and it is physically impossible for a ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Winter Leaf Yellowing in 'Hass' Avocado

open access: yes, 2007
The New Zealand avocado industry is worth $39.7 million in exports of 'Hass' avocados. Crop yields grew steadily from 1996 to 2001 to reach an average of 8.86 tonnes/ha. Since then however, crop yields have remained steady.
