The use of Fluidized Bed Chemical Vapor Deposition to coat particles or fibers is inherently slow and capital intensive, as it requires constant modifications to the equipment to account for changes in the characteristics of the substrates to be coated.
Concrete floor slab flatness and levelness are parameters often specified in construction documents that contractors must meet to ensure a high quality of construction. However, the measurement of these parameters is cumbersome and time-consuming.
Multi-terminal DC (MTdc) systems based on high-voltage DC (HVDC) transmission technology is an upcoming concept. In such systems, either asymmetric monopole or bi-pole systems are generally employed. Such systems are not suitable for easy expansion.
Stability performance of interconnected power grids plays crucial roles on their secure operation to prevent cascading failure and blackout.
This invention proposes a Honeycomb-DD coupling structure that addresses the shortcomings of the conventional honeycomb coil array and gathering the advantage of DD and honeycomb designs advantages in a single design.
Free-standing, thin films were fabricated with a binder resulting in nearly an order of magnitude thickness decrease while increasing porosity and activation energy. These effects of such diminished significantly. Free-standing films could be fabricated with a binder.
Porous carbons are the primary and imperative active materials for commercial supercapacitors because of their power capability, long-term cycle stability, wide operating temperatures, and high Coulombic efficiencies.
Additively manufacturing of the windings with a conductor distributed in the cross-section according to the Hilbert curve provides many benefits as it allows for the reduction of the high-frequency losses due to the reduction of the effective winding conductor size.
A deposition tool was developed that enables rehabilitating lining application within live natural gas pipelines without requiring trenching and removal/replacement of the pipelines. This lining technology creates a fully renewed pipeline.
Wireless charging systems need to operate at high frequency, at or near resonance, to maximize power transfer distance and efficiency. High voltages appear across the inductors and capacitors. The use of discrete components reduces efficiency, increases system complexity.
