Cellulose nanostructure-based biodegradable nanocomposite foams: A brief overview on the recent advancements and perspectives

Author: Motloung, Mpho P ; Ojijo, Vincent O ; Bandyopadhyay, Jayita ; Ray, Suprakash S Date: Jul 2019 The interest in designing new environmentally friendly materials has led to the development of biodegradable foams as a potential substitute to most currently used fossil fuel–derived polymer foams. Despite the possibility of developing ... Read more
Cure kinetics, morphology development, and rheology of a high-performance carbon-fiber-reinforced epoxy composite

Author: Mphahlele, Keletso ; Ray, Suprakash S ; Kolesnikov, A Date: Nov 2019 Carbon-fiber-reinforced polymer (CFRP) is a thermosetting high-performance epoxy composite used in the manufacturing of advanced aircraft components. The curing kinetics and rheological characteristics can have a great effect on the macroscopic ... Read more
Development, characterization, and in vitro evaluation of water soluble poloxamer/pluronic-mastic gum-gum acacia-based wound dressing

Author: Buyana, B ; Aderibigbe, BA ; Ray, Suprakash S ; Ndinteh, DT ; Fonkui, YT Date: Nov 2019 Bacterial infections are serious complications associated with wounds. Wounds can become chronic due to bacterial infections. In this research, lyophilized wound dressings were prepared from poloxamer, pluronic, mastic gum, and gum acacia. ... Read more
Electro-Fenton Degradation of Selected Antiretroviral Drugs Using a Low-cost iron-modified carbon-cloth electrode

Author: Emej, IC ; Ama, OM ; Khoele, K ; Osifo, PO ; Ray, Suprakash S Date: Mar 2021 Human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) causes morbidity and mortality in infected patients. These epidemics are significantly reduced and treated globally with antiretroviral drugs (ARVDs). However, ... Read more
Electrochemical preparation of iron-supported carbon-cloth electrode and its application in the in-situ production of hydrogen peroxide

Author: Emeji, I ; Ama, Monday O ; Osifo, P ; Ray, Suprakash S ; García-Rodríguez, O ; Lefebvre, O Date: Aug 2019 This study describes how carbon-cloth (CC) electrode was demonstrated to have good electrical conductivity using linear sweep voltammetry (LSV). Its electrocatalytic activity was evaluated toward the generation of hydrogen peroxide (H2O2) via ... Read more
Investigation of graphene loaded polypyrrole for lithium-ion battery

Author: Folorunso, O ; Hamam, Y ; Sadiku, R ; Adekoya, GJ ; Ray, Suprakash S Date: Apr 2020 The discredit state of lithium-ion (Ln) battery is as a result of the challenges associated with electrodes, inadequate power and energy densities. For a battery to be classified as suitable for electric vehicle and grid power suppliers, ... Read more
Kinetically controlled localization of carbon nanotubes in polylactide/poly(vinylidenefluoride) blend nanocomposites and their influence on electromagnetic interference shielding, electrical conductivity, and rheological properties

Author: Salehiyan, Reza ; Nofar, M ; Ray, Suprakash S ; Ojijo, Vincent O Date: Jul 2019 This study illustrates the effects of the kinetic parameters [processing time, polyvinylidene fluoride (PVDF) viscosity, carbon nanotube (CNT) aspect ratio, and processing method] on the CNT migration and consequently the viscoelastic properties, ...

Morphology modulated photocatalytic activity of CeO2 nanostructures for selective oxidation of biobased alphaPinene to oxygenates

Author: Mavuso, MA ; Makgwane, Peter R ; Ray, Suprakash S Date: Nov 2020 The effective Ce3+/Ce4+ redox and oxygen mobility of CeO2 induced by tunable nanostructure morphology has attracted a great interest in photocatalytic organic synthesis. Herein, we report on the microwave‐assisted synthesis of CeO2 with ... Read more
Parametric analysis of electrical conductivity of polymer-composites

Author: Folorunso, O ; Hamam, Y ; Sadiku, R ; Ray, Suprakash S ; Joseph, A Date: Jul 2019 The problem associated with mixtures of llers and polymers is that they result in mechanical degradation of the material (polymer) as the ller content increases. This problem will increase the weight of the material and manufacturing cost. ... Read more
Rheology and foaming behaviour of styrene–ethylene–butylene–styrene nanocomposites

Author: Banerjee, R ; Ray, Suprakash S ; Ghosh, AK Date: Jun 2020 The dependence of the foaming behaviour of a polymeric material on its material characteristics and foaming temperature gives rise to the research question that how the degree of dispersion/distribution of nanoparticles and the resulting ... Read more
Sustainable chemicals: A brief survey of the Furans

Author: Iroegbu, AO ; Sadiku, ER ; Ray, Suprakash S ; Hamam, Y Date: Feb 2020 Whether it is in the textiles, paints and coatings, energy sector, polymers, plastics, woods, sugar chemistry, pharmacy, aerospace and the automotive industries, the multiplicity of applications of furans and their derivatives, have made ...
