Arrhenius and non-Arrhenius conductivities in intercalated polymer electrolytes

open access: yesThe Journal of Chemical Physics, 1998
Intercalated polymer electrolytes (IPEs), Cd0.75PS3A0.5(PEO) [A=Li, Na, K, Cs], formed by the insertion of alkali metal ions solvated by polyethylene oxide (PEO) into the interlamellar space of the layered insulating cadmium thio-phosphate form an interesting class of materials.

Anti-Arrhenius Passage of Gaseous Molecules through 2D Membranes [PDF]

open access: yes, 2022
Chemical reactions and other physicochemical phenomena are known to follow the Arrhenius-like kinetics, i.e. they are accelerated upon heating and vice versa. There exist though stepwise processes which rates can decrease with temperature if, for example,

Reconsideration On The Role Of The Specific Heat Ratio In Arrhenius Law Applications [PDF]

open access: yes, 2008
Arrhenius law implicates that only those molecules which possess the internal energy greater than the activation energy E-a can react. However, the internal energy will not be proportional to the gas temperature if the specific heat ratio gamma and the ...

Estimation of strength degradation for engineering plastic (Under elevated temperature and humidity stress test)

open access: yesNihon Kikai Gakkai ronbunshu, 2019
A large quantity of engineering plastics are used in electric industrial products. It is necessary to estimate the life of the product made of engineering plastics because of its shorter life and lower strength than some of ceramics or metals.

Mathematical Modelling of Some Nutrient Losses during Heat Treatment of Stewed Apples

open access: yesCzech Journal of Food Sciences, 2009
Vitamin C (later noted VITC) and polyphenols (later noted PP) were regarded as main nutritional markers in the transformation process of stewed apples after an in situ measurement campaign at two leading French industrials on that matter.

Shelf-Life Prediction of Citrus Lemon Using a Multivariate Accelerated Shelf-Life Testing (MASLT) Approach

open access: yesJournal of Horticultural Research, 2022
The shelf life of agricultural products is characterized by several quality parameters simultaneously. Estimating the shelf life using the multivariate accelerated shelf-life testing (MASLT) approach is expected to provide a more accurate shelf-life ...
