Photodegradable Hydrogels for On‐Demand Modeling of Age‐Related Spatiotemporal ECM Deformation

Small, EarlyView.
A light‐tunable PEG hydrogel enables on‐demand, spatiotemporal modeling of drusen‐like ECM bulges in the aging outer retina. By precisely controlling bulge size, the platform reveals how retinal pigment epithelium morphology adapts to topographical changes without disrupting actin cytoskeleton or polarity, effectively mimicking early ageing before ...

Reduction, Softening, and Melting Characteristics of Mill Scale‐Based Briquettes for Blast Furnace Ironmaking

steel research international, EarlyView.
The study evaluates mill scale‐based briquettes, which meet industrial standards for shatter strength and exhibit a low decrepitation index. Despite their limited reducibility in nonisothermal reduction experiments, softening and melting results indicate potential application as a substitute for conventional acidic iron‐bearing materials for use in ...

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

Structural Concrete, EarlyView.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Compact tape‐driven sample delivery system for serial femtosecond crystallography

Journal of Applied Crystallography, EarlyView.
A tape‐driven liquid sample droplet delivery system for serial femtosecond crystallography is described.We have developed a compact tape drive (CoT) with on‐demand sample delivery for time‐resolved serial femtosecond crystallography (SFX) experiments, which can deliver sample droplets and/or initiate reactions with a drop‐on‐drop strategy.

Drivers of phenological transitions in the seedling life stage

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional ecology research has primarily focused on juvenile and adult plants even though regeneration from seed can be the most consequential life‐history bottleneck with cascading influence on later stages of growth and reproduction.
