Bioinspired Materials, Designs, and Manufacturing Strategies for Advanced Impact‐Resistant Helmets

open access: yesAdvanced Engineering Materials, EarlyView.
This review explores how bioinspired materials, structures, and manufacturing strategies transform helmet design to achieve enhanced impact resistance. Drawing inspiration from nacre, porcupine quills, beetle exoskeletons, and skull architectures, it highlights advances in auxetic lattices, nanocomposites, and functionally graded foams.

Encapsulating Laser‐Induced Graphene to Preserve its Electrical Properties and Enhance its Mechanical Robustness

open access: yesAdvanced Engineering Materials, EarlyView.
It is demonstrated that laser‐induced graphene (LIG) can be encapsulated while preserving its electrical conductivity and enhancing its mechanical properties. Unlike previous encapsulation attempts, the optimal conditions described here result in sheet resistance of ≈2 Ω sq−1, resistance increase of only 5% upon encapsulation, and vastly improved ...

The Possibility of a Green Revolution in Sub-Saharan Africa: Evidence from Kenya [PDF]

open access: yes
It is widely believed that a Green Revolution similar to the one achieved in Asia is impossible in Sub-Saharan Africa. Although grain yields have been stagnant in this region, there are some signs of the intensification of farming systems in the face of ...
