Novel pulse amplifying circuits by different characteristic impedance transmission lines
, 2006 Two novel circuits used to amplify electric pulses by the coupling of transmission lines of different characteristic impedance are described. The circuits are intended for doubling voltage pulses and for doubling current pulses. The former is composed by

Advanced Healthcare Materials, EarlyView.A multivalent DNA nanostructure‐enabled lateral flow assay was developed for rapid, ultrasensitive detection of porcine epidemic diarrhea virus (PEDV) nucleocapsid protein. Designer net‐shaped DNA nanostructures (DNA‐Net) presenting PEDV‐specific aptamers achieved ~1000‐fold enhanced binding, enabling detection of viral copies with Ct ≤ 37.42 within 10

Photothermal‐Activated Antibacterial Amyloid‐Polyphenol‐Iron Hydrogels for Synergistic Wound Healing
Advanced Healthcare Materials, EarlyView.We report a thermally triggered supramolecular hydrogel (LTFe) formed by Fe3+ and tannic acid on lysozyme amyloid fibrils. Fe3+ enables rapid gelation and photothermal transduction with an efficiency of 88.56%. The LTFe hydrogel exhibits excellent biocompatibility, potent antibacterial activity against E. coli and S.

Advanced 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

Portable low profile antenna at X-band
, 2011 An antenna which has been conceived as a portable system for satellite communications based on the recommendations ITU-R S.580-6 and ITU-R S.465-5 for small antennas, i.e., with a diameter lower than 50 wavelengths, is introduced.
