Portable Breathing Monitoring With Phase‐Resolved Airflow Dynamics Enabled by a Dual‐Response Flexible PZT Sensor

open access: yesAdvanced Healthcare Materials, EarlyView.
A portable respiratory monitoring device based on a flexible PZT sensor captures pressure‐ and temperature‐related airflow responses in a single waveform. Polarity‐opposed piezoelectric and pyroelectric components generate a narrow transient spike and a broad quasi‐steady peak during both inhalation and exhalation. This dual‐component structure enables

A simplification to the fast FIR-FFT filtering technique in the DSP interpolation process for band-limited signals

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2013
En ocasiones cuando se manipula una gran cantidad de datos muestreados, se requiere reducir dicha cantidad para conservar solo una representación de estos. Aquí dos aspectos son importantes; por un lado no se quiere que la cantidad de datos sea demasiado

Adaptable Covalent Organic Framework‐Hydrogel Microneedles for Glucose‐Responsive Isoliquiritigenin Delivery in Diabetic Wound Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
We develop a covalent organic framework‐loaded Traditional Chinese Medicine monomer nanodrug delivery system (ISL@bCOF) via boron‐oxygen bonds, a smart response to glucose for delivering AI‐driven isoliquiritigenin (ISL) targeting ZBP1. This dynamic release mechanism, combined with transdermal delivery technology via potent microneedles, can modulate ...

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

open access: yesAdvanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the
