Four different varieties of class F fly ashes, collected from different sources from the state of West Bengal (India) were mixed with lime in 9 : 1 wt ratio, followed by compaction of the mixes. The compacts were subjected to steam curing to develop an optimum strength by the reaction between fly ash and lime. The steam cured compacts were heated at different elevated temperatures and free lime...

The declining water availability for agriculture is becoming problematic for many countries. Therefore the study of plants under water restriction is acquiring extraordinary importance. Botanists currently follow the dehydration of plants comparing the fresh and dry weight of excised organs, or measuring their osmotic or water potentials; these are destructive methods inappropriate for in-vivo ...

We investigate the existence of specific/nonthermal microwave effects for the dehydration reaction of xylose to furfural in the presence of NaCl. Such effects are reported for sugars dehydration reactions in several literature reports. To this end, we adopted three approaches that compare microwave-assisted experiments with a) conventional heating experiments from the literature; b) simulated c...

This study aimed to determine the effects of osmotic dehydration on kinetics hot air drying apricot halves under conditions that were similar industrial ones. The process was performed in a sucrose solution at 40 and 60 °C concentrations 50% 65%. As expected increased temperatures resulted water loss, solid gain shrinkage. well described by Peleg model. effective diffusivity 5.50–7.387 × 10−9 m...

in this research, the effect of ultrasound-osmotic dehydration process in different conditions on the drying kinetics parameters of rhubarb was investigated. before dying process, rhubarb samples were placed in contact of ultrasound-osmotic pretreatment and then dried by convection hot air dryer equipped with circulated fan. the results showed that using osmotic pretreatment at 40% sucrose solu...

Cytosine monohydrate (CM) and anhydrate crystal forms reversibly interconvert under high temperatures or humidity conditions. Here, we demonstrate through defect engineering the ability to expand thermal stability range of CM targeted creation quantifiable defects in low-level concentrations. Twelve different molecular dyes with a variety core structures charges were screened as potential dopan...
