Halogen-free flame-retardant compounds. Thermal decomposition and flammability behavior for alternative polyethylene grades
(
MDPI AG
, 2019 , Article)
The effect of six halogen-free flame retardant (FR) formulations was investigated on the thermal stability of two low-density polyethylenes (LDPE) and one linear low-density polyethylene (LLDPE), by means of thermogravimetric ...
Letrozole-loaded nonionic surfactant vesicles prepared via a slurry-based proniosome technology: Formulation development and characterization
(
Elsevier
, 2020 , Article)
Slurry-based Letrozole (LTZ)-loaded proniosomes were designed using sucrose or sorbitol as carriers and various ratios of cholesterol (CH) and Tween 80 (T80) as lipid composition. Proniosomes were hydrated and probe-sonicated ...
The Current Status of Cytomegalovirus (CMV) Prevalence in the MENA region: a systematic review
(
MDPI
, 2019 , Article)
Human cytomegalovirus (CMV) is a highly prevalent herpesvirus worldwide. According to
the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO),
CMV infects people of all ages, and by ...
Electrocoagulation treatment of reject brine effluent from Solvay process
(
Desalination Publications
, 2019 , Article)
Solvay process is an efficient treatment technique for reject brine from desalination, where salinity
is reduced by removing Na+
by adding NH3
. However, in this process large amounts of NH3
are
consumed and Cl–
...
Global change effects on plant communities are magnified by time and the number of global change factors imposed
(
National Academy of Sciences
, 2019 , Article)
Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure ...
Synthesis of Aliphatic Acids from CO2 and Water at Efficiencies Close to the Photosynthesis Limit Using Mixed Copper and Iron Oxide Films
(
American Chemical Society
, 2019 , Article)
The photocatalytic conversion of CO2 and water into value-added chemicals remains a great challenge. This study shows that uniformly mixed copper and iron oxide (CuO/CuFeO2; CFO) bulky heterojunction films are capable of ...
Chemical modification of graphene with grape seed extract: Its structural, optical and antimicrobial properties
(
Elsevier Ltd
, 2019 , Article)
Herein, we modified for the first time thermally reduced graphene oxide (TRG) using grape seed extract (GSE), by simple probe sonication method. The effect of GSE on the structural changes of TRG has been carefully analyzed ...
Clay minerals damage quantification in sandstone rocks using core flooding and NMR
(
Springer Verlag
, 2019 , Article)
Sandstone oil reservoirs consist of different clay minerals such as kaolinite, illite, and chlorite. These clay minerals highly affect the formation damage during enhanced oil recovery (EOR) and well stimulation operations ...
Influence of polyelectrolyte architecture on the electrokinetics and dewaterability of industrial membrane bioreactor activated sludge
(
Academic Press
, 2019 , Article)
Improvement of sludge dewaterability is greatly hindered by the presence of large amounts of interstitial water molecules trapped in the sludge as a result of strong hydrophilic characteristics. This study has investigated ...
Developing Polyaniline Filled Isoprene Composite Fibers by Electrospinning: Effect of Filler Concentration on the Morphology and Glass Transition
(
Pleiades Publishing
, 2019 , Article)
Abstract: Sub micron and nano level fibers are produced from the polymer melts by applying an external electric field during electrospinning; however very few studies are reported on elastomer scaffolds formed by this ...
