Microalgae harvesting by pH adjusted coagulation-flocculation, recycling of the coagulant and the growth media
(
Elsevier Ltd
, 2016 , Article)
Coagulation-flocculation can be considered as one of the least energy intensive microalgae biomass harvesting processes. However, cost of the coagulant and biomass contamination are two critical issues that need to be ...
Long-term semi-continuous cultivation of a halo-tolerant Tetraselmis sp. using recycled growth media
(
Elsevier Ltd
, 2019 , Article)
In this study, a halotolerant Tetraselmis sp. was selected for 11-month outdoor semi-continuous cultivation in one sq. m raceway tank in the Qatari desert. A fraction of the culture was harvested using ferric chloride, and ...
Evidence of thermo and halotolerant Nannochloris isolate suitable for biodiesel production in Qatar Culture Collection of Cyanobacteria and Microalgae
(
Elsevier
, 2016 , Article)
The isolation of autochthonous microalgae, with high lipid-contents and biomass productivities is a crucial aspect of the development of commercial production of microalgae-based biodiesel as well as food security in ...
Heat transfer performance of paraffin wax based phase change materials applicable in building industry
(
Elsevier Ltd
, 2016 , Article)
Thermal characterization of phase change materials (PCMs) compose of linear low-density polyethylene (LLDPE), paraffin wax (W) with a melting point of 25 °C, and expanded graphite (EG), that are highly effective in thermal ...
Enzymatic pre-hydrolysis of organic fraction of municipal solid waste to enhance anaerobic digestion
(
Elsevier Ltd
, 2019 , Article)
Enzymatic pretreatment was proposed to enhance the anaerobic digestion of Organic Fraction of Municipal Solid Waste (OFMSW). Enzyme cocktails were produced at laboratory scale from Aspergillus niger fermentation on wheat ...

(
Elsevier B.V.
, 2018 , Article)
In this study, one hundred serum samples from healthy people and patients with rheumatoid arthritis (RA) were analyzed. Standard immunoassays for detection of 10 different RA markers and analysis of glycan markers on ...
Synthesis and characterisation of Co2+-incorporated ZnO nanoparticles prepared through a sol-gel method
(
Elsevier B.V.
, 2016 , Article)
The properties of ZnO nanoparticles were modified by doping them with cobalt ions (Co2+) in various compositions through a sol-gel route. The Co2+-doped ZnO nanoparticles were characterised using X-ray diffraction (XRD), ...
Drug-clay nanohybrids as sustained delivery systems
(
Elsevier Ltd
, 2016 , Article)
Biocompatible 2-dimensional layered compounds such as clays and layered double hydroxides (anionic clays) have been explored and utilized in drug delivery system for therapeutic application because they can safely encapsulate ...
The effect of site-specific spectral densities on the high-dimensional exciton-vibrational dynamics in the FMO complex
(
Elsevier B.V.
, 2017 , Article)
The coupled exciton-vibrational dynamics of a three-site model of the FMO complex is investigated using the Multi-layer Multi-configuration Time-dependent Hartree (ML-MCTDH) approach. Emphasis is put on the effect of the ...
