Modelling and simulation of the degradation of perfluorinated ion-exchange membranes in PEM fuel cells [PDF]
A polymer-electrolyte membrane fuel cell model that incorporates chemical degradation in perlfluorinated sulfonic acid membranes is developed. The model is based on conservation principles and includes a detailed description of the transport phenomena. A

Rehydrogenation of Sodium Borates to Close the NaBH4-H2 Cycle: A Review
In 2007, the US Department of Energy recommended a no-go on NaBH4 hydrolysis for onboard applications; however, the concept of a NaBH4-H2-PEMFC system has the potential to become a primary source for on-demand power supply.

Retrocausality in Quantum Phenomena and Chemical Evolution [PDF]
The interplay between retrocausality and the time-reversal symmetry of the dynamical law of quantum mechanics underscores the significance of the measurement dynamics with the use of indivisible and discrete quantum particles to be mediated. One example of empirical evidence demonstrating the significance of retrocausality going along with time ...

Extraction of Bioactive Compounds from C. vulgaris Biomass Using Deep Eutectic Solvents
C. vulgaris microalgae biomass was employed for the extraction of valuable bioactive compounds with deep eutectic-based solvents (DESs). Particularly, the Choline Chloride (ChCl) based DESs, ChCl:1,2 butanediol (1:4), ChCl:ethylene glycol (1:2), and ChCl:
