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.

Electrical Tuning of Ferrimagnetic Spin Alignment Angle and Compensation Temperature in Pt/IrMn3/CoGd Multilayers

open access: yesAdvanced Functional Materials, EarlyView.
Spin‐orbit torque controls the Néel vector of antiferromagnetic IrMn3, which selectively exchange‐couples with spins of Co only in the ferrimagnetic CoGd. This selective interfacial pinning induces the non‐collinear spiral spin configuration, leading to a non‐uniform distribution of local compensation temperature along the film thickness, and enabling ...

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Interpreting a Radical Prostatectomy Report

open access: yesJournal of Urological Surgery, 2019
Worldwide, clinically detected prostate cancer is the second most common malignancy, with an estimated 1.1 million new cases in 2012. Standard active treatments for prostate cancer include radiotherapy and/or radical prostatectomy (RP) (for clinically ...

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

open access: yesAdvanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Water‐Soluble, Enzyme‐Degradable, and Hydrolyzable STAR Particles for Enhanced Drug Delivery to Skin

open access: yesAdvanced Healthcare Materials, EarlyView.
Biodegradable polymer STAR particles fabricated from water‐soluble, enzyme‐degradable, and hydrolyzable materials significantly enhance intradermal drug delivery. By replacing conventional non‐biodegradable materials, these STAR particles address environmental and safety concerns while expanding the potential of skin‐based drug delivery technologies ...

Glycerination as an alternative technique for preserving Vertebrata (Osteichthyes and Reptilia): a proposal for teaching purposes

open access: yesActa Scientiarum: Biological Sciences
Biological specimens are essential for teaching, research, and extension, although they require effective preservation. The glycerination technique stands out for allowing specimens to be preserved dry, which saves costs and facilitates handling due to ...
