Thermochronology and exhumation rates of granitic intrusions at Mesa Central, Mexico

open access: yesInternational Geology Review, 2019
The Mesa Central of Mexico (MC) is an elevated plateau located 2000 m above sea level in central Mexico, where intrusions outcrop that register the history of exhumation-erosion occurring during the Late Cretaceous-Paleogene. The tectonic history of the region records formation of the Late Cretaceous-Paleogene ‘Mexican orogen’; this was followed by ...

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Encoded Cell‐Material Interactions to Reroute Cytokine Signaling for Regenerative Medicine

open access: yesAdvanced Healthcare Materials, EarlyView.
We present native MATRIX (Material Activated To Regulate Inducible gene eXpression), a co‐engineered material‐cell platform. Surfaces functionalized with antibodies for endogenous soluble ligands (e.g., IL‐1β or IL‐6) capture and immobilize ligands for presentation to a cognate, engineered synthetic Notch receptor, releasing a transcription factor (TF)

Maskless Fabrication of PLA‐Based Neural Arrays for CNS Recording and Stimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Biodegradable neural interfaces enable bidirectional communication with the CNS. Through electrochemical characterization, ageing tests with impedance monitoring, and in vivo validation, we assess the performance of PLA‐based epicortical and spinal implants.

Grafted Low‐Leakage Si/AlN p‐n Diodes Enabled by Fluorinated AlN Interface

open access: yesAdvanced Materials Interfaces, EarlyView.
This work demonstrates a fluorination‐based interface engineering strategy that transforms oxygen‐terminated AlN surfaces into fluorine‐terminated interfaces for grafted p‐Si/n‐AlN diodes. By combining pseudo‐ALE oxide removal, XeF2 fluorination, and ultrathin SiNx stabilization, the engineered interface suppresses defect‐assisted reverse leakage by ...
