Aim: The aim of this study is to synthesize and characterize the more efficient photocatalyst [zinc oxide nanoparticles (ZnONPs)] via the addition of dopant lanthanum (La) and pineapple peel extract. Pineapple peel as a ...

Tip-based plasmonic nanofocusing, which delivers light into a nanoscale region and achieves localized electromagnetic (EM) field enhancement beyond the diffraction limit, is highly desired for light-matter interaction-ba...

In this work, we report the room temperature ferromagnetism in Sn1‐xFexO2 and Sn1‐xNixO2 (x = 0.00, 0.03 and 0.05) nano‐crystalline powders. All the samples were prepared using co‐precipitation me...

2D materials such as transition metal dichalcogenides (TMDCs) are a new class of atomic-layer materials possessing optical and electric properties that significantly depend on the number of layers. Electronic transitions...

Metallic nanoparticles supporting a localized surface plasmon resonance have emerged as promising platforms for nanoscopic labels, sensors, and (photo-) catalysts. To use nanoparticles in these capacities, and to gain me...

Abstract Manipulating light at the nanoscale with minimal loss remains a central challenge for nanophotonic technologies that can be tackled by using the direction-dependent polariton modes supported by anisotropic mater...

We have synthesized large scale, thin, transparent graphene oxide (GO) flakes by Hummer’s method and investigated their suitability for fabrication of transparent nanocomposites. The GO flakes were comprehensively char...

Two different approaches are used to produce conducting polymer nano-objects. One is a “top-down” approach which involves laser ablation of conducting polymer films using laser light interference patterns (direct las...

Abstract A novel Schiff base (L) was synthesized via the condensation of folic acid with salicylaldehyde, and its copper (II) complex (Cu–L complex) was subsequently prepared, exhibiting notable biological activity. Co...

van der Waals (vdW) materials supporting phonon polaritons (PhPs) – light coupled to lattice vibrations – have gathered significant interest because of their intrinsic anisotropy and low losses. In particular, α-MoO...

We introduce a method for optically imaging intracellular proteins at nanometer spatial resolution. Numerous sparse subsets of photoactivatable fluorescent protein molecules were activated, localized (to approximately 2 ...

Anthraquinones-rich extracts of Heterophyllaea pustulata Hook f. (Rubiaceae) exhibited in vitro antiviral activity against Herpes Simplex Virus Type I, from which several anthraquinones (AQs) were isolated and identified...

The purpose of this study was to investigate the impregnation of chitosan microspheres with the natural dye curcuma. The impregnation with curcuma dye was investigated in aqueous medium at pH 9.0, 9.5 and 10.0. The proce...

O objetivo deste trabalho foi determinar a influência dos parâmetros de nebulização no rendimento, granulometria e morfologia das micropartículas de quitosana como potencial carreadores da insulina. Quitosana a 1% e...

Se estudió el polimorfismo de la glibenclamida, caracterizándose cuatro formas cristalinas anhidras identificadas como: monoclínica centrada en la base (polimorfo IV), monoclínica simple (polimorfo III), ortorrómbic...

Tesis Energía y Ambiente (maestría) - Instituto Tecnológico de Buenos Aires, Buenos Aires - Karlsruher Institut für Technologie, Karlsruhe, 2024 "In the global effort to reduce greenhouse gas emissions and enhance en...

We disclose a morpho-anatomical study of Asclepias curassavica L. and Asclepias mellodora St.-Hil., collected in the Province of Santa Fe, Argentina. Whole plants of both species are commercialized for external and int...

The aim of the present study was to prepare, characterize and in-vitro evaluation of a Winsor-IV type microemulsion based drug delivery system incorporating celecoxib as BCS class-II model drug. Attempts were made to pre...

En este trabajo se han estudiado varios de los diferentes procesos que tienen lugar durante el calentamiento y la fusión de superficies de aceros al carbono producidos por irradiación con luz infrarroja coherente. En p...
