A Flower Sanctuary [PDF]

open access: yesNature, 1912
I BEG to thank Mr. Perrycoste for his letter in NATURE of September 19. The county of Somerset has for some time had a by-law similar to that of the county of Cornwall; but you will observe that the by-law does not justify the protection of any particular plant, and that the special flora of Cheddar might easily disappear without any violation of its ...

Digital Actuation Control of Soft Robotic Origami With Self‐Folding Liquid Crystal Elastomer Hinges

open access: yesAdvanced Functional Materials, EarlyView.
Self‐folding soft‐rigid hybrid robotic origami is enabled by liquid crystal elastomer actuators with embedded Joule heating and closed‐loop digital control. Digitally addressable hinges provide reversible and programmable transitions between distinct folded states while maintaining actuation performance at high cycle counts (over 1500).

Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

open access: yesAdvanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

open access: yesAdvanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

The Evolution of the FT/TFL1 Genes in Amaranthaceae and Their Expression Patterns in the Course of Vegetative Growth and Flowering in Chenopodium rubrum

open access: yesG3: Genes, Genomes, Genetics, 2016
The FT/TFL1 gene family controls important aspects of plant development: MFT-like genes affect germination, TFL1-like genes act as floral inhibitors, and FT-like genes are floral activators.

Mechanochromism of Glassy Polymers Enabled by a Loop‐Forming Supramolecular Mechanophore

open access: yesAdvanced Functional Materials, EarlyView.
The supramolecular mechanophore LOOP is covalently introduced into glassy polymers, capable of reporting force‐induced pre‐failure damage and local fracture events in polymer glasses. Under different mechanical deformation modes, including grinding, tensile stretching, and scratching, LOOP probes irreversible events in polymer glasses through a ...
