Effects of Scavenging System Configuration on In-Cylinder Air Flow Organization of an Opposed-Piston Two-Stroke Engine

open access: yes, 2015
In-cylinder air flow is very important from the point of view of mixture formation and combustion. In this direction, intake chamber structure and piston crown shape play a very crucial role for in-cylinder air pattern of opposed-piston two-stroke (OP2S)

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Embedded 3D‐Coaxial Bioprinting of Stenotic Brain Vessels with a Mechanically Enhanced Extracellular Matrix Bioink for Investigating Hemodynamic Force‐Induced Endothelial Responses

open access: yesAdvanced Functional Materials, EarlyView.
In this study, a physically enhanced vascular dECM bioink and used 3D‐coaxial bioprinting are developed to fabricate mature brain blood vessels for cerebral atherosclerosis research. This model demonstrates that vascular geometry‐induced hemodynamic changes trigger vascular inflammation, ensuring its potential for cerebrovascular research.

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.
