Decoding Hydrogel Porosity: Advancing the Structural Analysis of Hydrogels for Biomedical Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
Porosity governs transport mechanics in hydrogels, yet characterization in its native state remains challenging. This work harnesses particle tracking to uncover three‐dimensional pore geometric features in polyethylene glycol hydrogels. Measurements in the native state reveal pores characteristics are comparable to those obtained by cryogenic scanning

Animal‐Free Setup of a 3D Mature Adipocyte‐Macrophage Co‐Culture to Induce Inflammation In Vitro

open access: yesAdvanced Healthcare Materials, EarlyView.
A completely animal‐free 3D co‐culture is developed using human fat cells and immune cells. Animal‐based materials are replaced with gellan gum hydrogel and a serum‐free medium. Immune cells are effectively activated, producing specific inflammatory signals.

Progress of Immune‐Inducible Biomaterials for Post‐Ablation Cancers

open access: yesAdvanced Healthcare Materials, EarlyView.
The presence of residual tumors after ablative therapies poses a significant challenge, generally resulting in recurrence and metastases. This review offers a concise overview of immune‐inducible biomaterials from the perspective of the cancer‐immunity cycle, and how they enhance antitumor immunity through diverse mechanisms following ablative ...

Interstitial N‐Strengthened Copper‐Based Bioactive Conductive Dressings Combined with Electromagnetic Fields for Enhanced Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
This study developed a nitrogen‐strengthened copper‐iron‐zinc (N‐CuFeZn) alloy bioactive dressing integrated with electromagnetic stimulation. The coaxial dressing, made from 0.04 mm filaments with 1120 MPa tensile strength, showed that electromagnetic activation enhanced therapeutic outcomes by increasing VEGF expression, promoting angiogenesis (2.1 ...

Gain enhancement wideband CPW antenna based on artificial magnetic conductor

open access: yesScientific Reports
Unidirectional radiation and, hence, gain enhancement can be achieved by placing a primary radiator (simple antenna) at suitable height over a reflector to diminish back radiation and to enhance the forward radiation.

Printing and Rerouting of Elastic and Protease Responsive Shape Memory Hydrogel Filaments

open access: yesAdvanced Healthcare Materials, EarlyView.
A biofabrication strategy, Rerouting of Free‐Floating Suspended Hydrogel Filaments (REFRESH), is developed enabling the printing of highly elastic, reconfigurable protease‐responsive hydrogel filaments with shape memory properties. The filaments can be manually braided, knotted, and rerouted to create intricate cell‐laden 3D architectures, expanding ...

Measurement of High-Power Microwave Impulse Response Characteristics of Reflector Materials

open access: yesInternational Journal of Antennas and Propagation
High-power microwave (HPM) antenna, one of the key subsystems in the HPM system, is used for HPM radiation. Its performance is partly determined by the impulse responses of reflector materials under HPM.
