Preparation, characterization and toxicity evaluation ofCo3O4and NiO-filled multi-walled carbon nanotubes loaded to chitosan

Assessing carbon or tungstates coverage of ZrO2 nanoparticles supported on MWCNT via NOx-TPD

“…In agreement with our earlier studies [15,16], TEM images show that the outer surface of the MWCNT becomes uniformly decorated with ZrO 2 nanoparticles after grafting with Zr(acac) 4 and annealing in He (ZrO 2 (8.1)/MWCNT, Fig. 1b).…”

“…Since the original discovery of carbon nanotubes (CNT) by Ijima in the early nineties [1] the properties of these materials have been extensively studied in various fields [2][3][4][5]. In the catalysis domain, CNT and multi-walled carbon nanotubes (MWCNT) have been suggested to be promising catalyst supports or promoters, in particular when modified with metals and/or oxides [6,7].…”

“…From these studies it can be concluded that the size of the ZrO 2 particles were rather widespread [9][10][11] and higher than or equal to 10 nm in the majority of the synthetized samples [8,9,11,13,18,19]. Recently we proposed that narrowly distributed, highly dispersed, ZrO 2 nanoparticles (2-3 nm) could be obtained by grafting zirconium acetylacetonate (Zr(acac) 4 ) on MWCNT that were previously functionalized in nitric acid [14][15][16][17].…”

A review on allopathic and herbal nanofibrous drug delivery vehicles for cancer treatments

“…Drug confinement results in greater stability, tailored administration, and fewer adverse effects for patients, both of which are reasons of merit to use the encapsulation process instead of other traditional ones. Various drug delivery vehicles with varying surface physico-chemical properties, sizes, targeting methods, and architectures have been developed to date [ 10 , 11 , 12 ].…”

Self-Assembled chitosan/phospholipid nanoparticles: from fundamentals to preparation for advanced drug delivery

“…Specifically, chitosan is one positively charged natural alkaline polysaccharides derived from chitin that shows nontoxic in both animals and humans with many unique biological characteristics, such as the remarkable bioadhesiveness to mucosal surfaces and the ability to open tight junctions in epithelial cells to strongly promote drug penetration and absorption (Van der Lubben et al, 2001;Panos et al, 2008;Abdolhi et al, 2017;Raza & Anwar, 2017;Eid et al, 2018;Ejeromedoghene et al, 2018;Manuja et al, 2018;Augustine et al, 2019;Dutta et al, 2019). Phospholipids are negatively charged lipid mixtures and act as the basic component of biofilms with various surface activities.…”
