Laser &Photonics Reviews, EarlyView.Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.

Impact response of aluminum corrugated core sandwich panels
International Journal of Impact Engineering, 2013 AbstractThe mechanisms of projectile penetration of extruded 6061T6 aluminum alloy sandwich panels with empty and alumina filled, triangular corrugated cores have been experimentally investigated using zero obliquity, 12.7 mm diameter hard steel projectiles whose diameter was about a half that of the core's unit cell width.

Electron density distribution and screening in rippled graphene sheets [PDF]
, 2010 Single-layer graphene sheets are typically characterized by long-wavelength corrugations (ripples) which can be shown to be at the origin of rather strong potentials with both scalar and vector components. We present an extensive microscopic study, based

The Hidden Costs of Coffee Production in the Eastern African Value Chains
Sustainable Development, EarlyView.ABSTRACT There is increasing recognition that significant hidden costs associated with agrifood systems are not reflected in market prices. Coffee is among the three most traded agricultural commodities in the world and supports the livelihoods of more than 30 million smallholder households.

Leveraging Life Cycle Assessment for Informing Packaging Eco‐Design and Eco‐Modulation
Sustainable Development, EarlyView.ABSTRACT Eco‐modulation is designed to promote the adoption of eco‐design. However, in practice, its application is mostly concentrated on end‐of‐life (EoL) optimization. This study addresses the gap by proposing a framework to assess product–packaging systems as integrated units throughout the full life cycle.

Highly Dynamic Soft Electrohydraulic Origami Actuators for Agile and Multimodal Robotic Locomotion
SmartBot, EarlyView.Most current soft robots still lag far behind their natural counterparts in both agility and speed, mainly attributed to the limited morphing modes and performance of soft actuators. Here, the authors report a new methodology of electrohydraulic origami (EHO) for creating powerful and multimodal soft actuators with large strain, high speed, lightweight,
