Dual-Criteria Decision Analysis by Multiphotonic Effects in Nanostructured ZnO.

Simultaneous interrogation of pump and probe beams interacting in ZnO nanostructures of a two-wave mixing is proposed for dual-path data processing of optical signals by nonlinear optical effects. An enhancement in third-order nonlinear optical properties was exhibited by Al-doped ZnO thin films. Multiphoton absorption and nonlinear refraction were explored by the z-scan technique at 532 nm with nanosecond pulses.

Multiphotonic Ablation and Electro-Capacitive Effects Exhibited by Biofilms.

This work reports the modification in the homogeneity of ablation effects with the assistance of nonlinear optical phenomena exhibited by ATCC 10231, forming a biofilm. Equivalent optical energies with different levels of intensity were irradiated in comparative samples, and significant changes were observed. Nanosecond pulses provided by an Nd:YAG laser system at a 532 nm wavelength in a single-beam experiment were employed to explore the photodamage and the nonlinear optical transmittance.

Electrochemical conversion of CO using metal-organic framework catalysts.

Metal-organic frameworks (MOFs) have been an excellent platform for carbon dioxide reduction reactions (CORR). In this work, the feasibility of electrochemical reduction of CO to obtain C-deep value-added products was investigated by the preparation of Mg-containing MOF-74 samples combined with transition metal cations (Ni, Co and Zn). The prepared MOFs were used as electrocatalysts in CORR.

Synthesis and characterization of VO-GaO photocatalysts and their application on the photocatalytic reduction of CO.

The photocatalytic reduction of carbon dioxide (CO) to produce methanol (CHOH) is a promising strategy for producing clean energy. The catalyst, the aqueous medium, and the UV light are key parameters for the formation of the most relevant pair (e/h) and the specific selectivity towards the desired product (methanol). The use of GaO and VO in the photocatalytic reduction of CO to produce methanol has been little studied.

Navigation of Silver/Carbon Nanoantennas in Organic Fluids Explored by a Two-Wave Mixing.

Within this work are analyzed third-order nonlinear optical properties with a potential influence on the dynamic mechanics exhibited by metal/carbon nanofluids. The nanofluids were integrated by multiwall carbon nanotubes decorated with Ag nanoparticles suspended in ethanol or in acetone. Optical third-order nonlinearities were experimentally explored by vectorial two-wave mixing experiments with a Nd-YAG laser system emitting nanosecond pulses at a 532 nm wavelength.
