Attempts have been made to prepare nanoparticles based on poly(lactic-co-glycolic acid) (PLGA) and doxorubicin. Biological evaluation and physio-chemical characterizations were performed to elucidate the effects of initial drug loading and polymer composition on nanoparticle properties and its antitumor activity. PLGA…
Composites materials are used in many applications: solar cells, elements, light emitting diodes (LED), optoelectronic device, industrial applications in aircraft, military and car industry for their low cost, light weight, electrical properties, mechanical and optical properties.In this work, preparation of PS-PMMA c…
The structural and magnetic properties of Pr-alloyed MnBi (short MnBi-Pr) nanostructures with a range of Pr concentrations are investigated. The nanostructures include thin films having Pr concen-trations 0, 2, 3, 5, and 9 at.% and melt-spun ribbons having Pr concentrations 0%, 2%, 4%, and 6%, respectively. Addition o…
Composites are most successful materials used for recent works in the industry. Metal composites possess significantly improved properties including high tensile strength, toughness, hardness, low density and good wear resistance compared to alloys or any other metal. There has been an increasing interest in composite…
In this paper, synthesis of ZnO nanoparticles is done by a simple and facile surfactant assisted combustion synthesis. The synthesis of ZnO nanoparticles has been prepared using Zinc nitrate as a precursor material, glycine as a fuel with the support of non-ionic surfactant TWEEN 80. The obtained ZnO nanoparticles hav…
The aim of this study was to investigate the influence of the deposition temperature on the corrosion stability of the TiO2 layers. A metal organic chemical vapor deposition (MOCVD) system was used to grow TiO2 films at three different temperatures: 300°C, 400°C and 500°C. The electrochemical behavior of the films was…
Hexagonal nanostructured zinc–cadmium oxide [Zn(1−x)CdxO where x = 0.08, 0.15, and 0.17] solid solution thin films were deposited on FTO coated glass substrates from a common solution of zinc acetate and a newly developed polymeric cadmium precursor by an aerosol-assisted chemical vapour deposition (AACVD) technique.…
An amphiphilic Py-PCL-b-POEGMA copolymer was prepared by the combination of ring-opening polymerization (ROP) and atom transfer radical polymerization (ATRP). Based on the host-guest inclusion complexation of α-CD with densely grafted chains of the POEGMA shell in Py-PCL-b-POEGMA micelles, supramolecular micellar hydr…
The morphology of CeO2 nanomaterials determines their properties and synthesis of well dispersed CeO2 nanocrystals with desired morphology is thus crucial for their applications. In this paper, we report the successful synthesis of CeO2 nanocrystals with different morphologies anchored on graphene hybrid composites by…
The fast-growing area of materials prepared with the layer-by-layer (LbL) technique has become firmly established over the last three decades. Responsive LbL assemblies present one attractive type of LbL materials, useful in sensing, controlled delivery and actuation. However, stimuli-responsive LbL films made exclusi…
We synthesize the three-fold symmetric shield-like Au@Pd core-shell nanocrystals, enclosed predominantly by high-index {541} facets with kinks, through the simultaneous reduction of Au and Pd ions in the presence of triangular Au nanocrystal seeds in aqueous solution at room-temperature. The obtained shield-like Au@Pd…
In this study, we report on the synthesis of a dendron-functionalized poly(2-ethyl-2-oxazoline) in a one-pot cascade reaction approach. By means of a bifunctional small organic compound linker, namely (9-azidomethyl)anthracene, alkyne-functionalized PEtOx and maleimide-substituted dendron were coupled in a one-pot cas…
Epitaxial strain has been extensively used to control and induce new properties in complex oxide thin films. Understanding strain evolution and how to manipulate it are essential to the continued development of strain-induced effects in materials. The chemical complexity that underlies the diverse functionality of suc…
Orthogonally functionalized PEGs displaying alkenes and azides have been prepared and their dual-purpose scaffolding potential was exploited via click chemistry for controlled insertion of biorelevant moieties as well as facile fabrication of soft, non-toxic and degradable hydrogels.
In recent years, paramagnetic nanoparticles have shown great potential applications in many biological fields. Versatility in the use of super paramagnetic iron oxide nanocrystals in the field of biomedical applications, including targeted drug delivery, bioseparation, tissue repair, cancer treatment through hyperther…
We have designed a lightly crosslinked PEG based copolymer coating with compositional flexibility as well as extended stability for studying human mesenchymal stem cells (hMSCs). Copolymers contain a majority of poly(ethylene glycol) methyl ether methacrylate (PEGMEMA) as a cytophobic background with poly(ethylene gly…
We report a detailed DFT study of the energetic and structural properties of the spin-crossover Co(ii) complex [Co(tpy)(2)](2+) (tpy = 2,2':6',2''-terpyridine) in the low-spin (LS) and the high-spin (HS) states, using several generalized gradient approximation and hybrid functionals. In either spin-state, the results…
Glutathione-protected Ag clusters (Ag15, Ag25 and Ag29) function as photosensitizers when they are adsorbed on TiO2 electrodes. [Co(bpy)3](2+) is the most appropriate electron donor among the cobalt complexes examined. Ag15 clusters yielded the highest internal quantum efficiency of 28% at 460 nm in the presence of [C…
Due to its favorable relaxometric properties, Mn(2+) is an appealing metal ion for magnetic resonance imaging (MRI) contrast agents. This paper reports the synthesis and characterization of three new triazadicarboxylate-type ligands and their Mn(2+) chelates (NODAHep, 1,4,7-triazacyclononane-1,4-diacetate-7-heptanil;…
The π-π stacking interaction, one of the main intermolecular forces, sometimes leads to amazing magnetic properties. Although the concept has been raised that spin density is one of the main factors that contribute to the magnetic coupling strength in intermolecular magnetic coupling systems, it has not been confirmed…
