discuss the role of the free and specific volumesin the relaxation processes observed by DMTA (orDETA) and their significance for thermodynamic cal-culations of the state functions.ExperimentalThe polymeric samples are the same as used in theprevious works poly(methyl-4-pentene-1), PMP)[7–9]...
Temperature control.In terms of temperature control, the basic design and concept of a large reactor does not change significantly from the systems used in the laboratory. The process temperature in the systems is controlled by varying both the temperature and flow rate of the heat transfer fluid ...
The correlation between the number of hadronic interaction vertices in a shower and invisible energy is found to be strong and is used to estimate invisible energy fraction in highly granular calorimeters in short time intervals (<10 ns). We simulated images of hadronic showers using GEANT4 and...
Isoperibolic calorimetry monitors hydration process in real-life conditions, while isothermal calorimetry does it at a defined chosen temperature. Zinc was added to the cement in the form of two soluble salts of Zn(NO 3 ) 2 , ZnCl 2 and a poorly soluble compound ZnO. The concentration of ...
This model was used for the oxygen-rich case where the model-free methods are inapplicable to determine the apparent activation energies during the oxidation of both the oils. The limitations associated are as follows: First, this method, owing to the assumptions, may not describe the real ...
During a change in temperature, DSC measures the heat radiated or absorbed by the sample based on the temperature difference between the sample and the reference material [3]. It is a versatile technique used to measure many variables such as heat of fusion, melting temperature, reaction energy...
around 25-30% of calories within an amount of protein, is the same amount required to digest it. So if eating 100 calories of protein, only around 75 calories make it into circulation after 25% worth are used in digesting it. (carbs and fats have low TEF; it takes very little to dig...
The development of new materials called geopolymers is described, which at the turn of the nineties brought a new state of the art in material design through the so-called wet process resulting in a specific amorphous state. The classical configuration of glasses prepared by quenching is used fo...
Wide angle X-ray scattering (WAXS) and differential scanning calorimetry (DSC) have been used to characterize the polymorphism of the solid matrix of LN before and after in vitro skin penetration assay. Cetyl palmitate LN with a loading capacity of 20% of vitamin E derivatives (with regard to...
A cone calorimeter was used in this experiment as it effectively replicates real-life fire scenarios, exhibits high repeatability, and allows for acquiring much combustion characteristic data on the test material in a single experiment [16].
