Evaluation of native microalgae from Tunisia using the pulse-amplitude-modulation measurement of chlorophyll fluorescence and a performance study in semi-continuous mode for biofuel production
(
BioMed Central Ltd.
, 2019 , Article)
Background: Microalgae are attracting much attention as a promising feedstock for renewable energy production, while simultaneously providing environmental benefits. So far, comparison studies for microalgae selection for ...
Erosion behaviour of API X100 pipeline steel at various impact angles and particle speeds
(
MDPI AG
, 2016 , Article)
Erosion is the gradual removal of material due to solid particle impingement and results in a failure of pipeline materials. In this study, a series of erosion tests were carried out to investigate the influence of particle ...
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 ...
Contemporary issues in Qatar’s food security
(
Middle East Institute, National University of Singapore
, 2018 , Other)
Qatar is one of the richest countries in the world. However, its domestic food production is so low that over 90 percent of its food supply has to be imported. This article provides some stylised facts on Qatar’s food ...
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 ...
