One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

open access: yesAdvanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...

A Novel Multidimensional Characteristic Modeling of Incompressible Convective Heat Transfer

open access: yesJournal of Applied Fluid Mechanics, 2016
A characteristic-based approach is developed for thermo-flow with finite volume methodology (FVM) in which multidimensional characteristic (MC) scheme is applied for convective fluxes.

Reconfiguring Hierarchical Porous Architecture of 2D Metal Nanosheets for Multifunctional Triboelectric Nanogenerators

open access: yesAdvanced Materials, EarlyView.
A hierarchically porous copper nanosheet‐based triboelectric nanogenerator (HPC‐TENG) delivers superior output, long‐term stability, and multifunctionality through scalable solution processing and structural reconfiguration. Beyond energy harvesting, the platform exhibits robust EMI shielding and efficient Joule heating.

Size‐Dependent Contact Angles of Microscopic Droplets on Ultra‐Smooth Silanized Surfaces Probed by Atomic Force Microscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Wetting is vital in many technologies, but remains hard to predict due to complex phase interactions. Young's law predicts macroscale wetting on ideal surfaces, while line tension theory is limited to nanoscale droplets. Here, using AFM, the scale gap is bridged by focusing on microscopic droplets and predicting their contact angle on real surfaces ...
