Effect of maturity on the moisture sorption isotherm of chili pepper (Mareko Fana variety)

Heliyon, 2020
The moisture sorption isotherm at three maturity levels of the Mareko Fana chili pepper variety (red, brown and green) has been studied in this paper. The sorption isotherm was determined based on the standard static gravimetric method using a glycerol ...

Trapping a Metastable Node in an Amorphous Metal-Organic Framework. [PDF]

Angew Chem Int Ed Engl
Frustrated assembly in an amorphous Fe‐BDC framework is shown to trap a distorted, metastable Fe3O node as the dominant local motif. X‐ray PDF analysis and DFT calculations reveal that rapid network percolation outpaces node relaxation, locking in a high‐energy puckered geometry.

DETERMINATION OF THE ISOSTERIC HEAT TO PLANTAIN PULP (musa paradisiaca) BY SORPTION ISOTHERMS

Dyna, 2008
Las isotermas de sorción para ser usadas en la simulación y diseño de procesos de secado y almacenamiento de alimentos deben ser representadas por modelos válidos dentro de las condiciones encontradas en la práctica industrial. Usando el modelo de Chung-Pfost y ajustado por desorción el calor isostérico neto y totalpara pulpa de plátano fueron ...

Effect of temperature and water activity on heat transfer in parsley leaves in the  range of temperatures 10–30 °C

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007
The equilibrium moisture contents of parsley leaves were measured by the gravimetric dynamic method with continuous recording of changes in sample weight. Consequently water activity values were determined. Henderson equation was found to be a good model
