Insight into the extraction and characterization of cellulose nanocrystals from date pits
(
Elsevier B.V.
, 2022 , Article)
This study aims to extract and characterize cellulose nanocrystals (CNCs) from date pits (DP), an agricultural solid waste. Two methods were used and optimized for the cellulose nanocrystals (CNCs) extraction, namely the ...
Evaluation by MALDI-TOF MS and PCA of the diversity of biosurfactants and their producing bacteria, as adaption to weathered oil components
(
Elsevier B.V.
, 2021 , Article)
Indigenous Qatari bacterial strains were isolated from highly weathered oil-contaminated sites, identified, and differentiated based on their protein profiles using matrix-assisted laser desorption ionization-time of flight ...
Insights into the removal of lithium and molybdenum from groundwater by adsorption onto activated carbon, bentonite, roasted date pits, and modified-roasted date pits
(
Elsevier Ltd
, 2022 , Article)
This study investigated the removal of lithium (Li) and molybdenum (Mo) from groundwater using activated carbon, bentonite, roasted date pits, and modified-roasted date pits as adsorbents under different experimental ...
Study of bacterial interactions in reconstituted hydrocarbon-degrading bacterial consortia from a local collection, for the bioremediation of weathered oily-soils
(
Elsevier B.V.
, 2021 , Article)
To enhance the process of bacterial remediation of weathered hydrocarbons, the area of Dukhan, Qatar, was considered as a model for weathering processes. Self-purification by indigenous hydrocarbon-degrading bacteria showed ...
Spectral and Structural Properties of High-Quality Reduced Graphene Oxide Produced via a Simple Approach Using Tetraethylenepentamine
(
MDPI
, 2022 , Article)
A simple temperature-assisted solution interaction technique was used to functionalize and reduce graphene oxide (GO) using tetraethylenepentamine (TEPA) with less chemicals, low temperature, and without using other reducing ...
Functionalized cellulose nanocrystals as a novel adsorption material for removal of boron from water
(
Elsevier Ltd
, 2021 , Article)
This study aims to prepare a novel adsorbent containing cellulose nanocrystals (CNC) isolated from date pits (DP) and ionic liquid (IL). The prepared composite of CNC and IL was then loaded onto the DP to prepare IL-CNC@DP ...
Immobilization of heavy metals by microbially induced carbonate precipitation using hydrocarbon-degrading ureolytic bacteria
(
Elsevier
, 2022 , Article)
Crude oil contamination introduces multiple threats to human health and the environment, most of which are from toxic heavy metals. Heavy metals cause significant threats because of their persistence, toxicity, and ...
SARS-CoV-2 does not replicate in HaCaT spontaneously immortalized human keratinocytes: implications for the pathogenesis of COVID-19-associated skin manifestations
(
John Libbey Eurotext
, 2022 , Article)
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-related cutaneous manifestations have been reported [1], however, the direct or indirect role of SARS-CoV-2 infection in their pathophysiology is still debated ...
Error-feedback temperature regulation for a reverse flow reactor driven by a distributed parameter exosystem
(
Elsevier
, 2022 , Article)
This work is devoted to solve the state and error-feedback control problems for a catalytic reverse flow reactor (CFRR), which is modeled by nonlinear partial differential equations (PDEs). These two regulation problems ...
Design and Microinjection of Morpholino Antisense Oligonucleotides and mRNA into Zebrafish Embryos to Elucidate Specific Gene Function in Heart Development
(
MyJove Corporation
, 2022 , Article)
The morpholino oligomer-based knockdown system has been used to identify the function of various gene products through loss or reduced expression. Morpholinos (MOs) have the advantage in biological stability over DNA oligos ...
