Introducing a self-consistent test and the corresponding modification in the Barrett, Joyner and Halenda method for pore-size determination
(Elsevier, 2014-12)
A standard method to obtain the mesopore size distribution of adsorbents is the Barrett, Joyner and Halenda (BJH) analysis of the N2 adsorption?desorption isotherm at 77 K. The availability, over the last two decades, of ...

Drying and autogenous shrinkage of pastes and mortars with activated slag cement
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Activated slag cement (ASC) shows significantly higher shrinkage than ordinary Portland cement agglomerates. Cracking generated by shrinkage is one of the most critical drawbacks for broader applications of this promising ...
SOIL WATER RETENTION CURVE AND S INDEX AS SOIL PHYSICAL QUALITY INDICATORS FOR INTEGRATED PRODUCTION SYSTEMS
(Soc Brasil Engenharia Agricola, 2018-01-01)
Assess the physical quality of agricultural soils it is important to establish the management more adequate for plant growth. In this study, the soil water retention curve and S index as indicators of soil physical quality ...
On the computer simulations of carbon nanoparticles porosity: statistical mechanics model for CO2 and N2 adsorption isotherms
(Springer, 2018-11)
A new approach model was developed for the pore size characterization of carbon porous materials, using adsorption gases. The experimental adsorption isotherms of CO2 and N2 onto carbon nanoparticles were used to test the ...
Bimodal mesoporous hard carbons from stabilized resorcinol-formaldehyde resin and silica template with enhanced adsorption capacity
(Elsevier Science Sa, 2019-03)
Hard carbon powders with hierarchical mesoporous structure from resorcinol-formaldehyde polymer were successfully prepared by use of double pore forming method. Poly-diallyldimethylammonium chloride (pDADMAC) and commercial ...
