Molecular Dynamics Simulations of Water Confined in Calcite Slit Pores: An NMR Spin Relaxation and Hydrogen Bond Analysis
(American Chemical Society, 2017-03)
We study water confined in calcite (104) slit pores from 6 to 1 nm by molecular dynamics. By determining NMR parameters combined with hydrogen bond network analysis, we provide an important contribution to the understanding ...
Kinetics of human sperm acrosomal exocytosis
(Oxford University Press, 2014-09-01)
The acrosome reaction is a unique event in the lifespan of sperm characterized by the exocytosis of the acrosomal content and the release of hybrid vesicles formed by patches of the outer acrosomal membrane and the plasma ...
Soil structure changes induced by tillage systems
(Elsevier B.V., 2017-01-01)
Structure represents one of the main soil physical attributes indicators. The soil porous system (SPS) is directly linked to the soil structure. Water retention, movement, root development, gas diffusion and the conditions ...
Three-Dimensional Characterization of Pores in Ti-6Al-4V Alloy
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2011-01-01)
The direct three-dimensional characterization of opaque materials through serial sectioning makes possible to visualize and better quantify a material microstructure, using classical metallographic techniques coupled with ...

Recycling trachyte waste from the quarry to the brick industry: effects on physical and mechanical properties, and durability of new bricks
(Elsevier, 2018)
This work examined the possibility of recycling trachyte waste as temper for preparing new types of bricks, thus reducing disposal costs and requirements for increasingly vulnerable raw materials, ultimately reducing ...
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 ...
Influence of cassava starch content and sintering temperature on the alumina consolidation technique
(Elsevier B.V., 2009-06-01)
The influence of starch content and sintering temperature on the preparation of alumina bodies were studied. The process was water-based and cassava starch was used as consolidator, binder and pore former. Colloidal ...
Molecular Transport through TiO2Mesoporous Thin Films: Correlation with the Partially Blocked Electrode Model
(American Chemical Society, 2021-10)
Mesoporous titania thin film (MTTF)-based electrodes are vastly popular due to their versatility and their potential use as sensors, catalysts, and photovoltaic devices. For these applications, understanding of diffusion ...
