Mesoporous silica coated carbon nanofibers reduce embryotoxicity via ERK and JNK pathways
( Elsevier Ltd , 2021 , Article)Carbon nanofibers (CNFs) have been implicated in biomedical applications, yet, they are still considered as a potential hazard. Conversely, mesoporous silica is a biocompatible compound that has been used in various ... -
Nickel oxide carbon nanofiber composite for electrochemical oxidation of methanol
( Electrochemical Society Inc. , 2014 , Conference Paper)Electrospun fibers of a mixture of polyvinylpyrrolidone (PVP), polyaniline (PANI) and graphene were stabilized for 2 h at 200 °C and then carbonized at 800 °C for 5 h. Composites were prepared by depositing Ni(OH)2 on the ... -
Outwelling from arid mangrove systems is sustained by inwelling of seagrass productivity
( Inter-Research , 2014 , Article)Mangrove forest productivity is normally sustained by nutrients from terrestrial runoff, with freshwater inputs driving the resulting outwelling of production, but arid mangroves lack this input. The movement of material ... -
Pd/Ni-metal-organic framework-derived porous carbon nanosheets for efficient CO oxidation over a wide pH range
( Royal Society of Chemistry , 2022 , Article)Metal nanocrystal ornamented metal–organic frameworks (MOFs) are of particular interest in multidisciplinary applications; however, their electrocatalytic CO oxidation performance over wide pH ranges is not yet reported. ... -
Pilot-scale spiral wound membrane assessment for THM precursor rejection from upland waters
( Taylor and Francis Inc. , 2016 , Article)The outcomes of a pilot-scale study of the rejection of trihalomethanes (THMs) precursors by commercial ultrafiltration/nanofiltration (UF/NF) spiral-wound membrane elements are presented based on a single surface water ... -
Potential for green algae spirulina to capture carbon dioxide from gas stream
( TechConnect , 2016 , Conference Paper)This study evaluated the use of green algae Spirulina microalgae as a C02 capturing technology at different temperatures. The growth of Spirulina at 25 and 30◦C were studied in synthetic wastewater and its performance in ... -
Potential use of mixed indigenous microalgae for carbon dioxide bio-fixation and advanced wastewater treatment
( AIChE , 2017 , Conference Paper)The potential use of mixed indigenous microalgae (MIMA) as a CO2 capturing technology and treatment process for wastewaters was evaluated at two temperatures ( 25 and 30 C) and different CO2 dosage ( 0%, 5% and 15%). During ... -

Role of catalyst type in the selective separation of olefinic and paraffinic hydrocarbons using xerogel-based adsorbents
( Elsevier , 2008 , Article)Resorcinol-Formaldehyde (RF)-based activated carbon xerogels are typically synthesized using a homogeneous, sodium-based, catalyst solution. In this work, the synthesis of RF-based carbon xerogels using other, non-typical, ... -
Significant Toxic Effect of Carbon Nanofibers at the Early Stage of Embryogenesis
( NLM (Medline) , 2020 , Article)Implementation of carbon nanofibers (CNFs) in biomedical applications have successful outcomes, however, they are still considered as a potential hazard. We herein used avian embryos at 3 days and its chorioallantoic ... -
Spatial Isolation of Carbon and Silica in a Single Janus Mesoporous Nanoparticle with Tunable Amphiphilicity
( American Chemical Society , 2018 , Article)Like surfactants with tunable hydrocarbon chain length, Janus nanoparticles also possess the ability to stabilize emulsions. The volume ratio between the hydrophilic and hydrophobic domains in a single Janus nanoparticle ... -
Strength optimisation of mortar with CNTs and nanoclays
( Thomas Telford Services Ltd , 2016 , Article)This study explores the use of carbon nanotubes (CNTs) and nanoclays in cement mortars. The paper presents modelling and optimisation of the compressive and flexural strengths of cement mortars containing CNTs and the ... -
