Hydrophobic PbS nanocrystals (NCs) emitting in the near infrared spectral region were encapsulated in the core of micelles and in the bilayer of liposomes, respectively, to form polyethylene glycol (PEG)-grafted phospholipids. The phospholipid-based functionalization process of PbS NCs required the replacement of the…
The accurate molecular design of organic building blocks is of great importance for the creation of large supramolecular entities with precise dimensional organisation. Herein we report on the design of a new pyrene derivative that yields, through a hierarchical self-assembly process and in the absence of template, st…
The Indice de Polluo-Sensibilité Spécifique (IPS) is one of the most frequently used diatom index.Beside this, according to some studies in streams and small rivers the diatom ecological guilds might be effective tools for ecological quality assessment in the future, but the usability of them is not always clear.Our m…
In this study, composite polysulfone–polyvinylpyrrolidone (PSU–PVP) membranes were prepared using silver and copper loaded sepiolite as a filler.
The mechanism of the recent discovered enhanced flexoelectricity in perovskites has brought about numerous controversies which still remain unclear. In this paper, we employed relaxor 0.68Pb(Mg2/3Nb1/3)O3 -0.32PbTiO3 (PMN-PT) single crystals for study. The observed flexoelectric coefficient in PMN-PT single crystal re…
The use of electronically sorted ( <italic>i.e.</italic> semiconducting or metallic) single-walled carbon nanotubes (SWCNTs) for the removal of organic compounds from aqueous environments is investigated.
Superbenzene-bridged bis(permethyl-β-cyclodextrin) as a convenient and effective probe for trinitrophenol exploder.
Experiments show that polymeric nanoparticles often self-assemble into several non-close-packed lattices in addition to the face-centered cubic lattice. Here, we explore theoretically the possibility that the observed phase sequences may be associated with the softness of the particles, which are modeled as elastic sp…
The principal problem in the area of drug delivery is achieving better selectivity and controllability.
Nanostructured spinel zinc ferrite (ZnFe2O4) thin films were prepared, using the electrospray technique, as photoabsorber material for photoelectrochemical water splitting. An enhanced photocurrent of 53 μA cm−2 at 1.23 V versus RHE was achieved, which is among the best results obtained for unmodified ZnFe2O4 photoano…
To explore a convenient and efficient strategy for constructing tumor-targeted T 1 mCAs for MRI, hyperbranched poly(glycerol) prepared in one-pot was used to conjugate gadolinium chelates and folic acid ligands through “click chemistry”.
Environmentally conscious ceramics (ecoceramics) are a new class of biomimetic/biomorphic material that can be manufactured from renewable resources, such as wood from sustainable sources or wood wastes. The idea is to manufacture ceramics with the microstructure of wood. The wood is pyrolysed to convert it into carbo…
This article continues the review of studies (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) dealing with the passivation of various metals by solutions of organic corrosion inhibitors. It provides an overview of papers on the passivating properties of organophosphates, their complexes and salts. Th…
Transition metal dichalcogenide monolayers are highly interesting for potential valleytronic applications due to the coupling of spin and valley degrees of freedom and valley-selective excitonic transitions. However, ultrafast recombination of excitons in these materials poses a natural limit for applications so that…
Polypropylene (PP) is widely used as capacitor films due to its better dielectric, mechanical, and thermal performance. In order to reduce the cost and size of capacitor, high energy density for PP dielectric is pursued. Since energy density is in quadratic proportion to direct current (dc) breakdown strength for line…
PURPOSE: To investigate the effects of room-temperature etching with hydrofluoric acid (HF) in the presence and absence of ultrasonic irradiation on the bonding of yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) to resin. MATERIALS AND METHODS: Y-TZP specimens were etched with 40% HF at room temperature for…
We propose a geometrically and materially nonlinear discrete mechanical model of graphene that assigns an energetic cost to changes in bond lengths, bond angles, and dihedral angles.We formulate a variational equilibrium problem for a rectangular graphene sheet with assigned balanced forces and couples uniformly distr…
INTRODUCTION: This study has been carried out on reviewing the use of new synthetic component of zinc oxide nanoparticles (ZnO NPs) coated by Chitosan-linoleic acid (CS-LA) and to assess Minimum inhibitory concentration (MIC) of nanoparticles on clinical samples and biofilm formation in vitro. MATERIALS AND METHODS: A…
The corrosion inhibition of mild steel in 1 N HCl, H 2 SO 4 and HNO 3 solution in the presence of AZI at a temperature of 304 & 313 K was studied using weight loss techniques.The Neem (AZI) works as an inhibitor in the acid surroundings.The results showed that the inhibition efficiency was increased by increasing the…
Effect of thin film deposition route on the morphology and performance of molybdenum oxide (MoO 3 ) based electrochromic devices was investigated. For the deposition of thin films, a sequential deposition method, which includes ultrasonic spray pyrolysis (USP) and thermal evaporation methods was used. Films deposited…
