Tailoring the Bactericidal Activity of Ag Nanoparticles/α-AgWO Composite Induced by Electron Beam and Femtosecond Laser Irradiation: Integration of Experiment and Computational Modeling.

In nanotechnology research, significant effort is devoted to fabricating patterns of metallic nanoparticles on the surfaces of different semiconductors to find innovative materials with favorable characteristics, such as antimicrobial and photocatalytic properties, for novel applications. We present experimental and computational progress, involving a combined approach, on the antimicrobial activity against methicillin-resistant (MRSA) of as-synthesized α-AgWO samples and Ag nanoparticle composites (Ag NPs)/α-AgWO. The former included two morphologies: hexagonal rod-like (α-AgWO-R) and cuboid-like (α-AgWO-C), and the latter included composites formed under electron beam, Ag NPs/α-AgWO-RE and Ag NPs/α-AgWO-CE, and femtosecond (fs) laser irradiation, Ag NPs/α-AgWO-RL and Ag NPs/α-AgWO-CL.

Formation of Ag Nanoparticles on β-Ag2WO4 through Electron Beam Irradiation: A Synergetic Computational and Experimental Study.

In the present work, a combined theoretical and experimental study was performed on the structure, optical properties, and growth of Ag nanoparticles in metastable β-Ag2WO4 microcrystals. This material was synthesized using the precipitation method without the presence of surfactants. The structural behavior was analyzed using X-ray diffraction and Raman and infrared spectroscopy.
