A dynamic optimization framework for integration of design, control and scheduling of multi-product chemical processes under disturbance and uncertainty
(Elsevier, 2017-11-02)A novel dynamic optimization framework is presented for integration of design, control, and scheduling for multi-product processes in the presence of disturbances and parameter uncertainty. This framework proposes an ... -
Effect of chain stiffness on the entropic segregation of chain ends to the surface of a polymer melt
(2019)Entropic segregation of chain ends to the surface of a monodisperse polymer melt and its effect on surface tension is examined using self-consistent field theory (SCFT). In order to assess the dependence on chain stiffness, ... -
Effect of hemin, baicalein and heme oxygenase-1 (HO-1) enzyme activity inhibitors on Cd-induced accumulation of HO-1, HSPs and aggresome-like structures in Xenopus kidney epithelial cells
(Elsevier, 2018-08-01)Cadmium is a highly toxic environmental pollutant that can cause many adverse effects including cancer, neurological disease and kidney damage. Aquatic amphibians are particularly susceptible to this toxicant as it was ... -
The effect of hydrogen peroxide produced during ultraviolet disinfection of CHO cell culture media
(Elsevier, 2017-10-01)Ultraviolet (UV) irradiation is being considered for protection against viral contamination in cell culture media. Hydrogen peroxide (H2O2) produced by UV irradiation has been suggested as the cause for poor cell growth ... -
Effect of Nanoscopic Particles on the Mesophase Structure of Diblock Copolymers
(American Chemical Society, 2002)Introduction. The fabrication of novel biomimetic photonic and electronic materials requires the manipulation of both organic and inorganic materials at the nanometer length scale. One possible means of achieving this level ... -
The effects of filamentary Ni, graphene and lithium amide (LiNH2) additives on the dehydrogenation behavior of mechano-chemically synthesized crystalline manganese borohydride (Mn(BH4)2) and its solvent filtration/extraction
(Elsevier, 2018-04-01)Dehydrogenation properties of mechano-chemically synthesized crystalline Mn(BH4)2 hydride without and with ultrafine filamentary carbonyl nickel (Ni), graphene and LiNH2 were investigated. It is reported for the first time ... -
Electrodeposition and electrodissolution of zinc in mixed methanesulfonate-based electrolytes
(Elsevier, 2018-04-01)Zinc electrodeposition and electrodissolution in methanesulfonic acid (MSA) electrolytes mixed with chloride or sulfate are investigated in a 3-electrode cell for eventual use in divided and undivided zinc-cerium redox ... -
Embellished hollow spherical catalyst boosting activity and durability for oxygen reduction reaction
(Elsevier, 2018-09)Transition metals hybridized to heteroatom doped carbon material can be regarded as the most promising non-noble candidate for boosting the sluggish kinetics of oxygen reduction reaction (ORR). However, it has always been ... -
Encapsulation and controlled release of vitamin C in modified cellulose nanocrystal/chitosan nanocapsules
(Elsevier, 2021)Vitamin C (VC), widely used in food, pharmaceutical and cosmetic products, is susceptible to degradation, and new formulations are necessary to maintain its stability. To address this challenge, VC encapsulation was achieved ... -
Entropic segregation of short polymers to the surface of a polydisperse melt
(Springer, 2017)Chain ends are known to have an entropic preference for the surface of a polymer melt, which in turn is expected to cause the short chains of a polydisperse melt to segregate to the surface. Here, we examine this entropic ... -
Evaluation of Doped and Undoped Poly (o-anisidine) as Sensing Materials for a Sensor Array for Volatile Organic Compounds
(Wiley, 2020-06-02)Poly (o-anisidine) (PoANI) and PoANI doped with nickel oxide and zinc oxide were evaluated as sensing materials for four gas analytes (methanol, ethanol, acetone, and benzene). The sensing materials had high sensitivity ... -
Evaluation of Electrospun Fibrous Mats Targeted for Use as Flow Battery Electrodes
(The Electrochemical Society, 2017-07-14)Electrospinning was used to create custom-made fibrous electrode materials for redox flow batteries with targeted structural properties. The aim was to increase the available surface area for electrochemical reaction without ... -
