Promoted Disappearance of CO2 Hydrate Self-Preservation Effect by Surfactant SDS

open access: yesEnergies, 2021
The capture, storage and utilization of CO2 through hydrate-related technology is a promising approach to addressing the global warming issue. Dissociation is required after the transportation of CO2 gas in the form of a self-preserving hydrate. In order

Validation of data analysis routines for a thermal probe apparatus using numerical data sets [PDF]

open access: yes, 2008
Most thermal properties of construction materials used in the analysis of building performance have been measured under laboratory conditions, using a guarded hot box or hot plate apparatus. As a consequence, these properties seldom reflect the impact of

Effects of structural relaxation on cationic tracer diffusion in silicate melts [PDF]

open access: yes, 1989
The glass transition in silicate melts is a curve in time-temperature space marking the transition of the melt structure from an unrelaxed, disequilibrium glass to a relaxed, equilibrium liquid. Tracer diffusivity data obtained in glasses vs.

Chemical diffusion of fluorine in jadeite melt at high pressure [PDF]

open access: yes, 1984
The chemical diffusion of fluorine in jadeite melt has been investigated from 10 to 15 kbars and 1200 to 1400°C using diffusion couples of Jadeite melt and fluorine-bearing jadeite melt (6.3 wt.% F). The diffusion profile data indicate that the diffusion

Large-Scale Statistical Learning for Mass Transport Prediction in Porous Materials Using 90,000 Artificially Generated Microstructures

open access: yesFrontiers in Materials, 2021
Effective properties of functional materials crucially depend on their 3D microstructure. In this paper, we investigate quantitative relationships between descriptors of two-phase microstructures, consisting of solid and pores and their mass transport ...

Analysis of thermal-probe measurements using an iterative method to give sample conductivity and diffusivity data [PDF]

open access: yes, 2004
The application of Microsoft Excel Solver routines to analyze data from a thermal probe placed in a number of samples is described. The successful application of the Solver routine to the thermal probe temperature time data requires the selection of an ...

Determination of Effective Moisture Diffusivity of Banana Using Thermogravimetric Analysis [PDF]

open access: yes, 2014
Drying has been extensively used as a food preservation procedure. The longer life attained by drying is however accompanied by huge energy consumption and deterioration of quality. Moisture diffusivity is an important factor that is considered essential
