Oxyfluoride glasses obtained through incorporation of CaF2${\rm CaF}_2$ into photovoltaic cover glass melts

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The glass industry has limited options to mitigate its environmental footprint, and the demand for cover glass to produce photovoltaic panels continues to increase. Currently, the majority of this special type of glass is not being recycled; therefore, this work proposes to reuse it as raw material to obtain oxyfluoride glasses.

Analysis and Design Considerations of a Simplified LLC Three‐Port Resonant Converter

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
The growing demand for photovoltaic (PV) systems with integrated energy storage poses challenges for power conditioning, often requiring multiple converters that increase cost, complexity, and losses. Multiport resonant converters have emerged as an efficient alternative by integrating PV modules, energy storage systems (ESSs), and a DC bus within a ...

Spatial dispersion in Casimir forces: A brief review [PDF]

, 2005
We present the basic principles of non-local optics in connection with the calculation of the Casimir force between half-spaces and thin films. At currently accessible distances $L$, non-local corrections amount to about half a percent, but they ...

Active Power Regulation Through Dual Active Bridge Converter in Microgrids Employing MCPT‐Based Adaptive Dual Phase Shift Controller: Comparative Analysis

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
In this work, an adaptive dual phase shift (DPS) controller based on minimum current point tracking (MCPT) is introduced. The dual active bridge (DAB) converter is employed for regulating the active power in the microgrid whereas the propounded controller facilitates the same with enhanced efficiency through the perturb and observe (P&O) lagging ...
