Comparative Analysis of MPPT Control Techniques to Enhance Solar Energy Utilization and Convergence Time Under Varying Meteorological Conditions and Loads

open access: yesFrontiers in Energy Research, 2022
The electrical energy generated from solar energy photovoltaic (PV) technology is intermittent, varying, and irregular. With PV technology’s limited energy conversion efficiency, it is imperative to extract the maximum of converted energy.

Analysis of simultaneous time series of indoor, outdoor and soil air radon concentrations, meteorological and seismic data

open access: yesNukleonika, 2016
It is well known that the temporal dynamic of indoor and outdoor radon concentrations show complex patterns, which are partly not easy to interpret. Clearly, for physical reasons, they must be related to possibly variable conditions of radon generation ...

Water Losses During Technical Snow Production: Results From Field Experiments

open access: yesFrontiers in Earth Science, 2019
Alpine as well as Nordic skiing tourism strongly depend on the production of machine-made snow for the timely opening of the winter season. However, it is likely that sublimation, evaporation, wind drift, and the discharge of unfrozen water to the ground

Laser‐Welded Cellulose‐Carbon Nanotube Nanocomposites as a 3D Scaffold of Si Anodes for High‐Performance Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A Si anode comprising entangled networks of cellulose and SWCNT (C‐CNT) nanocomposites as an anode electrode for a high‐performance LIB is realized by fully utilizing the generated microstructure of a novel conductive 3D scaffold via a low‐temperature and eco‐friendly process. Additionally, localized heating via photo‐thermal conversion can be utilized
