Chitosan nanocapsules containing naproxen as an active ingredient were synthesized by ionic gelation method in presence of polyanion tripolyphosphate as a crosslinker. The morphology and diameter of the prepared chitosan nanoparticles was characterized using scanning electron microscopy and transition electron microsc…
The present paper reports the synthesis of cadmium and mercury free lamp (Y, Gd)BO3: Eu3+ phosphor which is in nano range useful for display device application. The phosphor doped with Eu3+ was synthesized by the solid state reaction method which is suitable for large scale production and eco-friendly. The prepared ph…
Polypyrrole–titanium dioxide brush-like nanocomposites show enhanced electrochemical performance and excellent cycling stability as an electrode material for supercapacitors.
The oxide heterostructure [(YFeO$_3$)$_5$(LaFeO$_3$)$_5$]$_{40}$, which is magnetically ordered and piezoelectric at room temperature, has been constructed from two weak ferromagnetic AFeO$_3$ perovskites with different A cations using RHEED-monitored pulsed laser deposition. The polarisation arises through the remova…
Triggering drug release in tumor or disease sites at specific times can be one approach to treat diseases efficiently by limiting side effects from high systemic or off-target exposure. In this study we investigated triggered drug release of a liposome gel by magnetic heating from Iron Oxide Magnetic Nanoparticles (IM…
Alizarin yellow GG (AYGG) is a natural dye used as a corrosion inhibitor. The inhibitive action of this compound against corrosion of carbon steel in hydrochloric acid solution (1M concentration), has been tested using the weight loss measurements and electrochemical measurements techniques. The results indicates this…
The electronic structure of CdTe nanotube–fullerene nanocomposites has been explored. Within this context, the structural and electronic properties of isolated 100 faceted CdTe nanotubes (NTs) with hexagonal cross-sections were first investigated using the self-consistent-charge density-functional tight-binding (SCC-D…
A novel electrosprayed bilayer film composed of an over-layer (L2) of aluminium-doped ZnO (AZO) nanoflakes (NF-AZO) and a under-layer (L1) of AZO nanocrystallites structure (NC-AZO) named BL:NF/NC-AZO is studied as an excellent field-emitter. The XRD pattern demonstrated that the doped bilayer film has preferential gr…
Microsol-electrospinning technique for facile fabricating core–shell microfibers to achieve incubated, controlled and sustainable release of water-soluble drugs.
Amongst the most interesting phenomena in correlated oxide systems are the doping-driven competitions between energetically similar ground states found in, e.g., high-Tc superconductors and colossal magnetoresistance manganites. It has recently been reported that doped multiferroics also exhibit this generic concept o…
The viologen-skeleton reacts with a hydrazine-terminated cyclotriphosphazene core to provide novel dendritic macromolecular asterisks that efficiently exchange, deliver and stabilize gold nanoparticles for up to eight months.
We present coarse-grained simulations of the self-assembly of 3-armed ABC star polyphiles. In systems of star polyphiles with two arms of equal length the simulations corroborate and expand previous findings from related miktoarm star terpolymer systems on the formation of patterns containing columnar domains whose se…
Under microwave (MW) irradiation at a proper temperature, three chromophores ( <bold>A</bold> , <bold>B</bold> and <bold>C</bold> ) with julolidinyl-based donors and TCF or CF <sub>3</sub> -Ph-TCF acceptors have been synthesized in high overall yields compared with the conventional heating method.
Carbon nanotubes (CNTs) belong to a specific class of nanomaterials with unique properties. Because of their anticipated use in a wide range of industrial applications, their toxicity is of increasing concern. In order to determine whether specific physicochemical characteristics of CNTs are responsible for their toxi…
Crystallization of poly( <sc>l</sc> -lactide) could be greatly enhanced by a montmorillonitic substrate favoring nucleation.
Electrochemical supercapacitors (SCs) have received much attention since their high power density, short charge/discharge duration and long cycle life. Heteroatom–doped carbonaceous materials have been investigated due to their exceptional electrochemical properties. In this study, boron–doped multi–walled carbon nano…
Polyester nanosponges were prepared with varied degrees of crosslinking densities of ∼4%, ∼7% and ∼10% and an average nanoscopic size of 100 nm. The crosslinking density and the influence towards the release kinetics of paclitaxel, a BCS class IV drug, for individual particles and a mixture of particles with two diffe…
A nacre protein, n16.3, forms phases that introduce textured mineral overgrowth and subsurface nanoporosities within calcite crystals.
In this paper, a novel single-phased white light emitting phosphor Na2Ca4Mg2Si4O15:Eu2+, Mn2+ was prepared successfully via the high temperature solid state reaction. The obtained Na2Ca4Mg2Si4O15:Eu2+ phosphor exhibits a broad excitation band ranging from 200 to 450 nm and a blue light emission band peaking at 480 nm,…
