Spatiotemporal Drug Delivery via a Neonatal Spinal Cord ECM Hydrogel for Biomimetic Microenvironment Remodeling After Spinal Cord Injury

open access: yesAdvanced Functional Materials, EarlyView.
A biomimetic hydrogel derived from neonatal spinal cord ECM (DNSCM) delivers LAMB2 protein and ISP peptide to remodel the inhibitory injury microenvironment. The system sustains drug release, upregulates pro‐regenerative LAMB2, downregulates inhibitory CSPG, and promotes axonal regeneration.

A ballast box to study the effect of sand fouling on ballast, track stiffness, track deformation, and predicting maintenance time

open access: yes
Zarembski, Allan M.Railroad track crossings through sandy areas, like deserts, face the unique challenge of sand infiltrating into the ballast, leading to ballast fouling.

Ballast stiffness estimation based on measurements during dynamic track stabilization [PDF]

open access: yes
Ballast compaction with the Dynamic Track Stabilizer (DTS) is known to improve the lateral track resistance by increasing the stiffness of the ballast. This paper presents two approaches for estimating the strain dependent ballast shear modulus G based ...

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

open access: yesAdvanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

A model for the stochastic prediction of track support stiffness

open access: yes, 2020
As well as guiding the train, one of the key aims of a railway track system is to provide support to the train at the wheel–rail interface that is of near-uniform compliance. Of the various components that make up this compliance, the contribution of the

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...
