Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

open access: yesAdvanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

PREDICTABILITY AND COMPLEXITY IN MACROECONOMICS. THE CASE OF GROSS FIXED CAPITAL FORMATION IN THE ROMANIAN ECONOMY [PDF]

open access: yes
There is a relationship between predictability and complexity. The problem of evaluating the complexity of the macroeconomic phenomenon can be reduced to decomposition into its principal components (which may have, in their turn, a certain degree of ...

International Institutions in Hard Times: How Complexity Increases Resilience

open access: yes, 2020
This paper asks how institutional complexity affects the resilience of global governance. By drawing on sociological differentiation theory, it interprets growing levels of institutional complexity as a process of institutional differentiation which ...

Growing through knowledge: examining the knowledge–complexity relationship in Africa

open access: yesDevelopment Studies Research
The limited diversification and sophistication of productive structures across African countries are often cited as fundamental reasons the continent remains in a ‘poverty trap.’ Our study examines the extent to which African countries can leverage the ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

open access: yesAdvanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...
