Understanding the interfacial activity of polysaccharide nanoparticles adsorbed at oil-water interfaces is essential and important for the application of these nanoparticles as Pickering stabilizers. The interfacial properties of starch-based nanospheres (SNPs) at the interface of an n-hexane-water system were investi…
The effects of multi-walled carbon nanotubes (MWCNTs) and nanosilica on tensile behavior of woven carbon fabric-reinforced epoxy composites have been studied. Multi-scale composites with epoxy matrices modified with different MWCNT and nanosilica contents (0.1, 0.5 and 0.9 wt.%) have been fabricated by vacuum-assisted…
We report measurements on yttrium iron garnet (YIG) thin films grown on both gadolinium gallium garnet (GGG) and yttrium aluminium garnet (YAG) substrates, with and without thin Pt top layers. We provide three principal results: the observation of an interfacial region at the Pt/YIG interface, we place a limit on the…
We discuss the equivalent form of Levy-Leblond equation [1, 2] such that the nilpotent matrices are two dimensional. We show that this equation can be obtained in the non-relativistic limit of the (2+1) dimensional Dirac equation. Furthermore, we analyze the case with four dimensional matrices and propose a Hamiltonia…
Recently, a new type of two-dimensional layered material, i.e. C3N, has been fabricated by polymerization of 2,3-diaminophenazine and used to fabricate a field-effect transistor device with an on/off current ratio reaching 5.5E10 (Adv. Mater. 2017, 1605625). Here we have performed a comprehensive first-principles stud…
In this study, nanocrystalline Cd 1-x Zn x S (x=0, 0.4, 0.8) were synthesized by co precipitation method. Material characterization was done by X-ray diffraction (XRD), Scanning electron microscopy (SEM) and UV-Vis absorption spectroscopy. From XRD data, it is noticed that the particle size of CdS is changed due to th…
Introduction Cyclic compounds and theirderivatives possess remarkable capacity for coordination withtransition metals giving rise to coordination compounds with variable structural geometry, presently, there is a rising attention in the ligand chemistry of structurally modified bio-ligands. Organ

Abstract In this communication, we report for the first time the nucleation and growth of metallic Ag nanoparticles on the surface of 3D flower‐like Ag 4 V 2 O 7 crystals, induced by accelerated electron beam irradiation. The growth of metallic Ag on the surfaces of Ag 4 V 2 O 7 crystals were studied by transmission e…
In this paper, free vibration characteristics of functionally graded (FG) nanobeams embedded on elastic medium are investigated based on third order shear deformation (Reddy) beam theory by presenting a Navier type solution for the first time. The material properties of FG nanobeam are assumed to vary gradually along…
Poly(β amino ester) polymers have received growing attention in the literature, owing to their ease of synthesis, versatile co-monomer selection, and highly tunable degradation kinetics. As such, they have shown extensive potential in many biomedical applications as well. In this work, it is demonstrated for the first…
EVA copolymer foils are widely used as encapsulants for photovoltaic (PV) cells in PV modules. These foils need to be crosslinked during module manufacturing, to enhance their properties. Accurate and reliable methods for the determination of their crosslinking degree are thus very important. In this work, two semi-em…
Abstract Scale and corrosion testing under high surface shear flow conditions, and selection of effective inhibitors, is of increasing importance in oilfield production. Extremely high wall shear stresses, up to 10,000 Pa, can be generated in production systems, for example in inflow control devices, and as such there…
Abstract Downhole scale deposition in the Khuff sour gas wells in Saudi Arabia has been a persistent problem, which negatively affects operation and production. Scale deposits are composed of predominantly iron sulfides with other types of minerals also present. Mechanical descaling treatment, although expensive and t…
In this paper, a frequency-based analytical approach is presented for dynamic analysis of three-phase balanced systems in the presence of harmonic distortion based on single-phase analysis. By providing mathematical foundation, this study proves that a three-phase balanced system (linear or non-linear, supplied by per…
In this paper, the critical buckling temperature of single-walled Boron Nitride nanotube (SWBNNT) is estimated using a new nonlocal first-order shear deformation beam theory. The present model is capable of capturing both small scale effect and transverse shear deformation effects of SWBNNT and is based on assumption…
A nano-carrier based on bacterial outer membrane vesicles has been prepared, which can stimulate the secretion of cytokines and may have immunomodulatory effects.
In the present study a new co-crystal of Ticagrelor with L-Tartaric acid has been prepared with improved solubility. Ticagrelor is a class VI drug with poor solubility and permeability; hence an attempt has been made to improve its solubility by co-crystallization technology.A co-crystal is a structurally homogeneous…
Abstract Often, scale inhibitors (SIs) applied in oilfields are organic phosphorus compounds, either phosphonates, phosphorus containing polymers, or phosphate esters. The latter group of SIs, phosphate esters, have not been as extensively studied as the others and we focus on these in this paper. The current work is…
In this paper, the buckling, and free vibration analysis of tapered functionally graded carbon nanotube reinforced composite (FG-CNTRC) micro Reddy beam under longitudinal magnetic field using finite element method (FEM) is investigated. It is noted that the material properties of matrix is considered as Poly methyl m…
