The laser remelting technique is considered a promising and effective method for improving the surface of thermally sprayed coatings, eliminating microstructural defects such as pores and cracks, increasing the life of parts and equipment by increasing microhardness and increasing anchoring force between coating and substrate. In the present work, ...

Structural bonding is a beneficial technique extensively used in numerous industrial fields. This technique is however prone to structural defects such as pores, which are created during the mixing of the adhesive and during the shaping of the joint. Depending on their characteristics, these pores are likely to influence the mechanical behaviour of...

Hydrothermal synthesis followed by a calcination step was used to prepare porous Zn2SnO4 powders using carbon black as a pore-forming agent. The porous Zn2SnO4 was used as a photocatalyst to degrade the Rhodamine B dye from aqueous solution under UV artificial light. X-ray diffraction, N2adsorption-desorption isotherms, and UV-Vis diffuse reflectan...

The purpose of this study was to solve the plateau phase (the stage in which the drug in the microsphere undergoes a slow release or almost no release after initial release) problem by understanding the effect of polymer blends on the internal pore changes of the microspheres. This study used PLGA 5050 4H (F-1), PLGA 5050 1A: PLGA 5050 4H = 3:7 (F-...

One of the most important microvasculatures' geometrical variables is number of pores per capillary length that can be evaluated using MRI. The transportation of blood from inner to outer parts of the capillary is studied by the pores and the relationship among capillary wall thickness, size and the number of pores is examined. Characterization of ...

BackgroundStarch is the main source of energy in commonly used pig diets. Besides effects related to the extent of starch digestion, also several effects related to variation in digestion rate have recently been demonstrated in non-ruminants. Different rates of starch digestion in animals and in in vitro models have been reported, depending on the ...

Low-field nuclear magnetic resonance (NMR), as a nondestructive and time saving method, has been widely used to evaluate the petrophysical properties of coalbed methane (CBM) reservoirs. To better understand the impacts of pore structures on permeability, NMR T2 spectrums of different rank coals and their meaning to porosity and permeability were i...

The aim of this study was to understand the pore formation mechanisms of degrading poly(d,l-lactic-co-glycolic acid) (PLGA) microparticulate systems. This was investigated through an original microparticles cross-section imaging method. Atorvastatin (ATV)-loaded 16- to 18-μm spherical microparticles with polymers of varying molecular weights (8 to ...
