Aluminium-doped (3%) zinc oxide thin films (AZO) were prepared, using pulsed laser deposition, with varying deposition times. The target was fabricated from compacted aluminium-doped nano-powder produced by sol–gel. had a growth consisting of nanostructures in the form columns sharp ends which, for certain times, resemble nano-flowers or nano-leaves. small spheroid-like particles created during columnar act as seed other AZO needles, resulting appearance lotus-like flowers and even smaller...
The main objective of this work is the preparation decorative zirconium oxynitride, ZrOxNy, thin films by dc reactive magnetron sputtering. Film properties were analyzed as a function gas flow and correlated with observed structural changes. Measurements showed systematic decrease in deposition rate increase revealed three distinct modes: (i) metallic mode, (ii) transition mode (subdivided into zones), (iii) an oxide mode. measurements target potential also consistent these changes,...
In this study, multicore-like iron oxide (Fe3O4) and manganese ferrite (MnFe2O4) nanoparticles were synthesized combined with nanogels based on chitosan alginate to obtain a multimodal drug delivery system. The exhibited crystalline structures displayed sizes of 20 ± 3 nm 11 2 (MnFe2O4). Fe3O4 showed higher saturation magnetization heating efficiency compared the MnFe2O4 nanoparticles. Functionalization citrate bovine serum albumin was found improve stability modified surface properties....
Thin films containing monometallic (Ag,Au) and bimetallic (Ag–Au) noble nanoparticles were dispersed in TiO2, using reactive magnetron sputtering post-deposition thermal annealing. The influence of metal concentration annealing the (micro)structural evolution was studied, its correlation with localized surface plasmon resonance (LSPR) enhanced Raman spectroscopy (SERS) behaviours evaluated. Ag/TiO2 presented columnar to granular microstructures, developing Ag clusters at for higher...
Carbon monoxide (CO) is a highly flammable and toxic gas to humans animals, that's why its detection monitoring are crucial. A promising technique develop robust cheap sensor, operating at room temperature, Localized Surface Plasmon Resonance (LSPR) sensing. However, LSPR sensing of inorganic molecules, such as CO, challenging due their extremely small differences in refractive indices. In this work, nanoplasmonic thin film, composed Au NPs semi-embedded CuO matrix (Au:CuO) was...
Currently, the nanoparticle functionalization effect on supramolecular peptide-based hydrogels remains undescribed, but is expected to affect hydrogels’ self-assembly and final magnetic gel properties. Herein, two different functionalized nanoparticles: citrate-stabilized (14.4 ± 2.6 nm) lipid-coated (8.9 2.1 nanoparticles, were used for formation of dehydropeptide-based magnetogels consisting ultra-short hydrogelator Cbz-L-Met-Z-ΔPhe-OH, with an assessment their over The nanoparticles...
In order to take advantage of the enormous potential graphene for future electronic microcircuits and other applications it is necessary develop reliable, rapid, widely applicable methods visualize graphene-based structures. We report here on a microdroplet condensation technique, which allows quick visual identification variety substrates, including some were previously considered unsuitable visualization carbon layers. The technique should also be artificially patterned structures are...
Supramolecular hydrogels, particularly low‐molecular‐weight peptide are promising drug delivery systems due to their ability change the solubility, targeting, metabolism and toxicity of drugs. Magneto‐plasmonic liposomes, in addition being remotely controllable with application an external magnetic field, also increase efficiency encapsulated release through thermal stimulation, for example, optical hyperthermia. Thus, combination those two materials—giving magneto‐plasmonic lipogels—brings...
