Engineering Aging: Approaches to Model and Deconstruct Biological Complexity

open access: yesAdvanced Materials, EarlyView.
The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.

Neuroimmune Microenvironment Reprogramming via Immuno‐piezoelectric Transducers for Synergistic Stem Cell Therapy in Traumatic Brain Injury

open access: yesAdvanced Materials, EarlyView.
A novel immuno‐piezoelectric transducer is innovatively developed. This device promotes neural stem cell (NSC) differentiation and maturation via ultrasound‐induced electrical stimulation and it amplifies the therapeutic efficacy of NSC in traumatic brain injury (TBI) by modulating the immune microenvironment. This piezoelectric transducer with “immune‐

Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Solvent‐Free Phase Separation of Polystyrene‐block‐poly(2‐hydroxyethyl methacrylate) Forming Freestanding Photonic Films

open access: yesAdvanced Materials Interfaces, EarlyView.
This work presents a scalable, eco‐friendly approach to forming microstructured block copolymer (BCP) films within 15 min through hot pressing. This process enables phase separation even for high‐molecular‐weight BCPs, which are often trapped in spherical structures using time‐consuming solvent processes.

Nanoscale Friction of Manganite Superlattice Films Controlled by Layer Thickness and Fluorine Content

open access: yesAdvanced Materials Interfaces, EarlyView.
Nanoscale friction in manganite superlattice films is probed by lateral force microscopy, revealing systematic effects of fluorine doping and top‐layer thickness. Friction coefficients are tuned through viscoelastic dissipation extending several nanometers below the surface.

Ultraflat Honeycomb Stanene Nanoribbons on Au(111)

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel striped phase of Sn on Au(111) is investigated using STM, LEED, and XPS. This structure consists of alternating, ultraflat honeycomb stanene nanoribbons and square‐like Sn stripes. Sn coverage, controlled by temperature‐driven desorption, governs the structural evolution.
