Programmable Guest‐Induced 5‐Phase‐Transition Topological Reconstructions of Cobalt Formate Metal–Organic Frameworks

open access: yesAdvanced Science, EarlyView.
A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.

An Injectable, Self‐Expanding Hemostatic Foam for Field‐Compatible Postpartum Hemorrhage Management

open access: yesAdvanced Science, EarlyView.
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...

A low‐profile tri‐band shared‐aperture antenna for Sub‐6G wide‐beam and millimetre‐wave high‐gain applications

open access: yesIET Microwaves, Antennas & Propagation
To achieve multi‐function integration and independent performance regulation of microwave and millimetre‐wave (mm‐Wave) shared‐aperture antennas, a design method based on embedded structure fusion is proposed.

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

open access: yesAdvanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Printing‐Assisted Integration of Thermal, Fluidic and Electrical Components in Implants for Focal Brain Cooling

open access: yesAdvanced Science, EarlyView.
Extrusion‐based 3D printing of silicones and discrete electronic components are combined to create cortical implants for rodents that integrate thermal neuromodulation and electrical recording. Linked to an autonomous auxiliary driver unit, the system enables rapid, stable and localized hypothermia alongside ECoG recording.

A Robust Bio‐Supportive Hydrogel Patch for Full‐Thickness Repair of Gastroesophageal Defects

open access: yesAdvanced Science, EarlyView.
Gastroesophageal defect repair remains a formidable clinical challenge plagued by high leakage and life‐threatening complications. We develop a double‐disc, highly crystalline PVA‐based RBS hydrogel patch featuring suture‐free sealing, robust acid/enzyme resistance and mechanical durability.

Cavity‐Compatible Light Extraction in Top‐Emitting Microcavity OLEDs via a Gentle Internal Corrugation Layer and Resonance‐Matched Narrowband Emission

open access: yesAdvanced Science, EarlyView.
A gentle internal corrugation layer conformally reshapes the microcavity OLED stack, redistributing confined optical power toward extractable channels while preserving cavity‐controlled emission. Combined with optical clear resin and a resonance‐matched narrowband pTSF emissive system, this cavity‐compatible architecture delivers an external quantum ...

Nonlinear Ion‐Specific Control of Underwater Adhesion by Bottlebrush Polymer Interfaces

open access: yesAdvanced Science, EarlyView.
The efficiency of underwater adhesion is modulated by ion‐specific effects. Strongly hydrated Na+ remains separated from the mica surface by its hydration shell, preserving access to binding sites, whereas weakly hydrated K+ can partially dehydrate and occupy ditrigonal cavities.
