The aim of the present study was to prepare atorvastatin calcium (ATR) loaded poly(ε-caprolactone) nanoparticles (ALPNs) to enhance the oral bioavailability, efficacy and safety profile of drugs.
Titanium dioxide nanoparticles (TiO 2 NP) are possible carcinogenic materials (2B-IARC) and their toxicity depends on shape, size, and electrical charge of primary NP and on the system formed by NP media. The aim of this work was to characterize agglomerates of three TiO 2 NP by evaluating their morphometry, stability…
Upon 1560 nm excitation, higher energy levels of Er <sup>3+</sup> ions are populated. FRET and photons reabsorption to occur from NaYF <sub>4</sub> :Yb,Er to CdSe. Then activated CdSe produces electrons and holes in the conduction band and the valence band, respectively.
The grafting of trisilanolphenyl-polyhedral oligomeric silsesquioxanes (trisilanolphenyl-POSS) onto carbon fibers (CFs) was achieved using toluene-2,4-diisocyanate (TDI) as the bridging agent.
The orientation transition from perpendicular to parallel alignment of PEO cylindrical domains of PEO-b-PMA(Az) films has been demonstrated by extruding the block copolymer (BCP) solutions through a micropore of a plastic gastight syringe. The parallelized orientation of PEO domains induced by this micropore extrusion…
PEGylated core–shell BaYbF <sub>5</sub> :Tm@BaGdF <sub>5</sub> :Yb,Tm nanocrystals have been constructed and successfully applied in UCL imaging, CT imaging and MR imaging.
Quantum metamaterials generalize the concept of metamaterials (artificial optical media) to the case when their optical properties are determined by the interplay of quantum effects in the constituent 'artificial atoms' with the electromagnetic field modes in the system. The theoretical investigation of these structur…
Horizontal force during rolling as indicator of rolling process ability and technical conditions of main rolling equipment is considered. Relationships between horizontal impact force of work rolls chocks against housings (backup rolls chocks slots) and entry speeds of metal to work rolls bite during their gripping ar…
The corrosion property of three different steels is evaluated in a sweet environment with respect to Mn content and Cr addition. The result shows that high Mn content in steel suppresses the formation of protective FeCO 3 scale and it decreases its corrosion resistance in sweet environment. However, addition of 3 wt%…
Employing the hydroxyl groups on the surface of Cloisite® 30B montmorillonite (Cl30B), the ring-opening polymerization of L-lactide was performed with a metal-free catalyst to yield a PLLA-g-Cl30B nanohybrid with low Mn grafted PLLA chains (i.e., 9 kg mol−1). This nanohybrid was then melt mixed with PLA 4032D from Nat…
Blends of carbon black (CB)-filled co-continuous immiscible polystyrene/poly(methyl-methacrylate) (PS/PMMA) with a PS/PMMA ratio of 50/50 and CB selectively located in the PS phase have been prepared by melt blending. The simultaneous evolution of conductivity and phase morphology of blend composites was investigated…
In recent years, there has been a substantial increase in the research of plasmonic effects in catalysis motivated by the enhanced surface reactivity that can be achieved using resonant optical fields confined on the nanoscale. However, these plasmonic materials have not been extended to electrocatalysis applications.…
-SiNTs multifunctional drug delivery system led to remarkably destructed cells, large vacuoles, and irregular widening of tumor tissues. This collaborative strategy could pave the way towards high-performance nanotherapeutics with superior antitumor efficacy and reduced side effects.
Few studies have investigated the two-photon properties of graphene quantum dots (GQDs) and GQD-conjugated polymers. The results of the present study revealed that conjugated polymers containing nitrogen and sulfur atoms caused higher quantum confinement of emissive energy to be trapped on the surface of nanomaterials…
Proton-functionalized g-C <sub>3</sub> N <sub>4</sub> was synthesized using thiourea and HNO <sub>3</sub> as source materials under microwave for only 3 min.
has shown its peculiar chemical reactivity due to both a strong base character and an unexpected oxidative ability towards the alcoholic function of glycol ethers. All the synthesized complexes exhibit, in water solution, an orange emission centred at 606 nm. Moreover, all complexes display the ability to give rise to…
Supported cobalt oxide catalysts with controlled size and morphologies were facilely synthesized and had high activity for styrene oxidation.
The Mg( <sc>i</sc> ) compound (LMg) <sub>2</sub> reacts with (trip <sub>2</sub> Sn) <sub>2</sub> with formation of the metalloid Sn <sub>10</sub> trip <sub>8</sub> cluster <bold>1</bold> , which contains Sn atoms in the formal oxidations states 0, +I and +II, while the stronger Mg( <sc>i</sc> ) reductant (L′Mg) <sub>2…
Schematic for the preparation of PAN/PVA membrane deposited on the stainless steel mesh modified by dilute PVA solution.
The versatility of the surfactant-free synthesis of hollow organosilica nanoparticles was shown in terms of particle diameters and organic moieties. The porous structures were investigated precisely by advanced adsorption–desorption measurements.
