Effects of Total Harmonic Distortion on Power System Equipment [PDF]

, 2015
Total harmonic distortion, or THD, is the summation of all harmonic components of the voltage or current t waveform compared against the fundamental component of the voltage or current wave: Harmonic is a sinusoidal component of a periodic wave or ...

Ultra‐Thin Tow‐Based Discontinuous Composites—Material Overview and Aspirations

Advanced Functional Materials, EarlyView.
Tow‐based discontinuous composites made from ultra‐thin tapes offer outstanding in‐plane mechanical properties. This material, inspired by Nacre, has high volume fraction of tapes exceeding 90 % and allows for quasi‐isotropic material plates less than 100 micrometer in thickness.

Bone Organoids Across the Development‐to‐Remodeling Continuum: From Tissue Formation to Functional Competence and Translation

Advanced Healthcare Materials, EarlyView.
Mineralization alone does not establish a mature bone organoid. This Review integrates biological foundations, materials design, adaptive remodeling, and translational validation through the development‐to‐remodeling continuum (DRC). By separating biological functions from the evidence supporting them, the framework exposes critical gaps in current ...
