(
Frontiers Media
, 2021 , Article)
The aim of this study was to evaluate the role of chronic cadmium exposure in modulating cardiac matrix metalloproteinases (MMPs) in the heart of rats. Adult male Sprague-Dawley rats were exposed to 15 ppm CdCl2 in drinking ...
Effect of anions on the structural, morphological and dielectric properties of hydrothermally synthesized hydroxyapatite nanoparticles
(
Springer Nature
, 2020 , Article)
Synthetic nano hydroxyapatites (HA) have been considered as potential biomaterials for bone tissue engineering applications because of its excellent biological properties. The present work deals with the synthesis of HA ...
Materials and technologies for the tertiary treatment of produced water contaminated by oil impurities through nonfibrous deep-bed media: A review
(
MDPI AG
, 2020 , Article)
This review covers various aspects of the treatment of emulsified oil/water mixtures and is particularly focused on tertiary treatment, which means the reduction of the oil content from 70-100 ppm to below 10 ppm, depending ...
