Identification of Molecular Fluorophore as a Component of Carbon Dots able to Induce Gelation in a Fluorescent Multivalent-Metal-Ion-Free Alginate Hydrogel
(
Nature Publishing Group
, 2019 , Article)
We introduce a simple approach to fabricate fluorescent multivalent metal ion-free alginate hydrogels, which can be produced using carbon dots accessible from natural sources (citric acid and L-cysteine). Molecular fluorophore ...
Pyrolysis Process as a Sustainable Management Option of Poultry Manure: Characterization of the Derived Biochars and Assessment of their Nutrient Release Capacities
(
MDPI
, 2019 , Article)
Raw poultry manure (RPM) and its derived biochars at temperatures of 400 (B400) and 600 ◦C (B600) were physico-chemically characterized, and their ability to release nutrients was assessed under static conditions. The ...
Development, validation, and application of School Audit Tool (SAT): An effective instrument for assessing traffic safety and operation around schools
(
MDPI AG
, 2019 , Article)
There is a need for a reliable school audit tool with well-defined scales to convert qualitative evaluation of existing school sites into a quantitative assessment in order to help public agencies to improve schools' safety ...
An efficient eco advanced oxidation process for phenol mineralization using a 2D/3D nanocomposite photocatalyst and visible light irradiations
(
Nature Publishing Group
, 2017 , Article)
Nanocomposites (CNTi) with different mass ratios of carbon nitride (C3N4) and TiO2 nanoparticles were prepared hydrothermally. Different characterization techniques were used including X-ray diffraction (XRD), UV-Vis diffuse ...
Potential of novel desert microalgae and cyanobacteria for commercial applications and CO2 sequestration
(
Springer Netherlands
, 2019 , Article)
CO2 fixation by phototrophic microalgae and cyanobacteria is seen as a possible global carbon emissions reducer; however, novel microalgae and cyanobacterial strains with tolerance to elevated temperatures and CO2 ...
Mixed Viral-Bacterial Infections and Their Effects on Gut Microbiota and Clinical Illnesses in Children.
(
Nature Research
, 2019 , Article)
Acute gastroenteritis remains a major cause of morbidity and mortality among young children worldwide. It accounts for approximately 1.34 million deaths annually in children younger than five years. Infection can be caused ...
Microstructure and compressive behavior of Al-Y2O3 nanocomposites prepared by microwave-assisted mechanical alloying
(
MDPI AG
, 2019 , Article)
In this study, Al–Y2O3 nanocomposites were synthesized via mechanical alloying and microwave-assisted sintering. The effect of different levels of yttrium oxide on the microstructural and mechanical properties of the Al–Y2O3 ...
QATARI FEMALE MANAGERS IN A WORLD OF PATRIARCHY
(
GIAP Journals
, 2019 , Article)
Purpose: The State of Qatar has widely sought to include women in public life and has implemented several policies in order to improve gender equality in the workforce and fair distribution of development benefits. This ...
Regional stratigraphy, facies distribution, and hydrocarbons potential of the Oligocene strata across the Arabian Plate and Western Iran
(
Springer Verlag
, 2019 , Article)
Major global events during the Oligocene epoch included a climatic change from warm “greenhouse” to a cooler “icehouse” that was accompanied by the onset of Antarctic glaciation. These events led to decline in water ...
Highly efficient photocatalytic z-scheme hydrogen production over oxygen-deficient WO3-x nanorods supported Zn0.3Cd0.7S heterostructure
(
Nature Publishing Group
, 2017 , Article)
The demand for clean renewable energy is increasing due to depleting fossil fuels and environmental concerns. Photocatalytic hydrogen production through water splitting is one such promising route to meet global energy ...
