From Geometry to Function: Programmable Mechanical Response in 3D‐Printed Adipose‐Inspired Soft Metamaterials

open access: yesAdvanced Functional Materials, EarlyView.
Geometry‐driven design of soft cellular metamaterials is systematically investigated by combining experiments, finite element modeling, and statistical prediction. The study quantifies how unit cell geometry and material properties govern stiffness, instability, densification, and energy absorption.

Bio‐Inspired Biopolymeric Implantable Platform for Localized and Sustained Drug Delivery in Solid Tumor Treatment

open access: yesAdvanced Functional Materials, EarlyView.
A bio‐inspired biopolymeric implantable drug delivery platform enables localized and sustained release of 7‐ethyl‐10‐hydroxycamptothecin (SN‐38) in solid tumor treatment. The three‐dimensional (3D) structured crosslinked‐chitosan implants are fabricated via 3D‐printed molds and provide drug release over 3 months, significantly inhibiting tumor growth ...

Charge Generation and Recombination Pathways in All‐Polymer Bulk Heterojunction Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Multimodal spectroscopy and device analysis reveal how field‐dependent charge generation, transport limitations, and non‐geminate recombination govern performance losses in all polymer solar cells. The results identify the key processes controlling charge extraction and recombination, providing insights for the design of more efficient all‐polymer ...

Flow around a circular cylinder set normal to a plane wake of an upstream circular cylinder

open access: yesJOURNAL OF THE FLOW VISUALIZATION SOCIETY OF JAPAN, 1987
In order to clarify flow around a circular cylinder set normal to a plane wake of an upstream circular cylinder of the same diameter, a windtunnel experiment and an open water-channel experiment have been performed at Reynolds-numbers ( based on the diameter of the cylinder and the main velocity ) of 2.9×104 and 680, respectively.

Two‐Photon Grayscale Lithography (2GL) of High Mechanical and Optical Quality 3D Silica Glass Microstructures

open access: yesAdvanced Functional Materials, EarlyView.
Two‐photon grayscale lithography (2GL) enables high‐speed and precise 3D printing of thermolyzed silica glass microstructures with optical‐grade surface quality, high quality factors, and mechanical strength utilizing a custom‐made pre‐glass resist based on polyhedral oligomeric silsesquioxane (POSS) modified with a high‐sensitivity Norrish type II ...

Effects of Regional Magnetic Field on Rotating MHD Flow Field of Unity Magnetic Prandtl Number

open access: yesJournal of Applied Mathematics, 2012
This work numerically studies the flow pattern of a magnetic fluid filled within an annulus whose inner cylinder is moving at a constant rotational speed, while the outer cylinder is stationary but under the influence of a nonuniform external magnetic ...

Development of Multifunctional Hierarchically Restructured Antibacterial Neural Interfacing Electrodes via Plasma‐Enhanced Atomic Layer Deposition of Zinc Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Next‐generation implantable neural‐interfacing devices are increasingly constrained by the coupled demands of electrode miniaturization, electrochemical performance, and implantation infection risk. Femtosecond laser–based hierarchical surface restructuring (HSR) technology has emerged as a scalable, manufacturing‐compatible platform for ...

Sound source localization of flow around circular cylinder by a virtual microphone array technique

open access: yesAIP Advances, 2018
Sound source localization technology is used to study the noise mechanism generated by flow around a circular cylinder. Detached-eddy simulation is performed to compute the flow field and the far-field noise is calculated with the Ffowcs Williams and ...
