Concurrently Achieving 4.6 W/M2 and 120,000 Cyclability Enabled by Extendable Swing Arms in Rotational Triboelectric Nanogenerator

open access: yesAdvanced Science, EarlyView.
A rotational energy harvesting device that successfully reconciles high power density with mechanical durability through a hybrid sliding‐and‐bouncing kinematic mechanism is reported. The success reported in our paper includes addressing a dilemma where enhanced electrical output comes at the cost of increased friction and wear, limiting the practical ...

Evaluation of the laboratory resilient modulus test using a New Mexico subgrade soil

open access: yes, 2012
Resilient modulus (Mr) is a laboratory determined parameter, where a cylindrical specimen is subjected to dynamic axial stresses under confining stresses, while axial deformations are measured.

Dual‐Network Protein Hydrogels Promote Rapid Hemostasis and Immune‐Regulated Scarless Tissue Regeneration

open access: yesAdvanced Science, EarlyView.
A dual‐network protein hydrogel substantially improves hemostasis and scar‐free healing.The adaptive network maintains intimate tissue contact while providing strong wet adhesion, tunable mechanics, and controlled degradation. Concurrent ROS scavenging and M2 polarization suppress fibrotic pathways, preventing scar formation.

Sulfur‑Containing Additives for Enhanced Kinetics and Interfacial Stability of Phosphorus Anodes in Li‑Ion Batteries

open access: yesAdvanced Science, EarlyView.
A novel synergistic strategy by employing dual functional sulfur‐containing additives of lithium sulfide (Li2S) and its oxidation product lithium sulfate (Li2SO4) was proposed. Li2SO4 absorbs the solvent molecules to direct the formation of a uniform, Li2O‐rich, and adaptive interphase, which accommodates volume expansion and suppresses parasitic ...

Aptamer‐Directed Porous DNA Nanocomposite Hydrogel for Active Pulp Preservation: Immunomodulation, Stem Cell Recruitment and Reparative Dentinogenesis

open access: yesAdvanced Science, EarlyView.
This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.
