Green preparation of phase-change solar container polymer microcapsules
Herein, we fabricated photothermal PCM microcapsules with melamine-formaldehyde resin (MF) as shell using cellulose nanocrystal (CNC) and graphene oxide (GO) co-stabilized Pickering emulsion droplets as templates.. The performance of solar-thermal conversion systems can be improved by incorporation of encapsulated phase change materials. In this study, for the first time, Crodatherm TM 60 as a phase change material (PCM) was successfully encapsulated within polyurea as the shell supporting material. While. . In this study, a new multi-criteria phase change material (PCM) selection methodology is presented, which considers relevant factors from an application and material handling point of view, such as hygroscopicity, metal compatibility (corrosion), level hazard, cost, and. . In this study, a new.

Electrolyte composition in all-vanadium liquid flow solar container battery
The electrolytes are novel, in that they contain additives of ammonium phosphate dibasic and magnesium chloride, which act to stabilize and improve the all-sulfate solution.. The all-vanadium redox flow battery is currently one of the most advanced battery systems because of the symmetric design of its positive and negative electrolyte solution. However, the thermal and chemical instabilities of V (V) species as well as the permeation problem have caused incompatibility. . Evaluation of electrolytes for all-vanadium redox-flow battery: thermal and chemical stability. [1] Y. Song at el., J. of Power Sources, vol. 480, p. 229141, 2020, doi: 10.1016/j.jpowsour.2020.229141. [2] J. Marschewski et al., Energy Environ. Sci., vol. 10, no. 3, pp. 780–787, 2017, doi:. . Redox flow batteries, especially all-vanadium-based flow batteries, that provide electrical energy converted from chemical energy are well suited to energy storage. They can tolerate fluctuating power supplies, repetitive charge/discharge cycles at maximum rates, and overcharging and.
