GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

An improved implantable temporary pacemaker electrode

The Journal of Thoracic and Cardiovascular Surgery, 1974
A new temporary pacemaker electrode, which leaves no exposed areas of wire when implanted, has been designed for use in postoperative cardiac surgical patients. The device, tested in 28 patients who underwent open-heart surgery, has significantly reduced the increase in myocardial threshold to pacing that occurs with the commonly used electrode ...
