Morphological adaptations of cervical vertebrae in plunge‐diving sulids

The Anatomical Record, EarlyView.
Abstract Foraging strategy frequently drives morphological diversification in birds. The plunge‐diving behavior of certain species makes the functional and ecological trade‐offs of variation in cervical vertebrae an especially intriguing question. This study compares cervical vertebrae across five plunge‐diving species and two non‐plunge‐diving species,

Restoring joint homeostasis: A dynamically adaptive meniscal scaffold prevents osteoarthritis by replicating native biomechanics

BMEMat, EarlyView.
This work establishes a paradigm shift from static structural mimicry to dynamic functional replication. By restoring the native “compression‐to‐tension” mechanism, the scaffold ensures robust mechanical stability and superior chondroprotection.

Initiating Market Formation Through Local Policy Innovation: Plot Handover as a Driver for Circular Construction

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition to circular construction suffers from uncertainties related to costs, market realities, supply, regulations and expertise using secondary materials in building projects. Uncertainties are large, and resolving them needs policy interventions.

Dynamic buckling of marine structures

, 2014
In this report the buckling resistance of marine structures when dynamic effects is important is investigated. A review of the governing theory is presented for both beam and plates. A sample of the different ways of solving the bucking problem is presented, and what kind of assumptions that are made.

Bolapolyphiles With Bulky Carbosilane‐Based Lateral Groups—Reticular Design of Liquid Crystalline Pentagonal Honeycombs

Chemistry – A European Journal, EarlyView.
T‐shaped bolapolyphiles with highly branched carbosilane‐based side‐groups self‐assemble into liquid crystalline honeycombs composed of type‐2 pentagonal prismatic cells and p2gg plane group symmetry. ABSTRACT Periodic pentagon tessellations are rarely observed in self‐assembled molecular systems.

Modular Assembly of a Biocatalytic Material for Stereoselective C─Si Bond Formation

Chemistry – A European Journal, EarlyView.
A modular, carrier‐free enzyme foam derived from Rhodothermus marinus cytochrome c combines structural stability with catalytic efficiency for stereoselective C─Si bond formation. Streptavidin (STV)‐mediated protein crosslinking creates a robust, self‐supporting materials platform for next‐generation biocatalysis.
