The electronic and optical properties of a composite created by introducing magnetite cluster into NaA zeolite have been investigated in this work using DFT calculations. results obtained indicate that the are enhanced because cluster. However, exhibited outside differ from those it presents when is part composite. It noteworthy exhibits magnetic half-semiconductor strong response within visible ultraviolet regions spectrum.
Work is reported on optical antennas of complex molecules. Optical a nanometric particle are widely considered for light relays in various on-chip applications. An appealing candidate an antenna molecule, example, huge cell containing few hundred atoms. The properties, such as the radiation patterns, may be optimized. optimization includes design and synthesis contents structures participating atoms their positions. A convenient method to simulate solve local field at sites atoms,...
Silver tetrahedral nanoparticles (NP) were synthesized using the inert gas condensation technique. We performed morphological and optical characterization of (NPs) atomic force microscopy (AFM), mass spectroscopy (MS), UV−visible spectroscopy. The Ag NPs produced by modified magnetron sputtering, followed thermalization in a high pressure zone. Along synthesis process, size was controlled through handling flow (Ar He), power, length aggregation optimized parameters to obtain peak on...
We study the assembling of small gold clusters subject to collisions and close contact coalescence by using molecular dynamics simulations simulate events that occur typically in sputtering process synthesis. Our results support notion kinetics processes strongly determine geometry structure final particle. While impact velocities, relative orientations, initial shape interacting particles are unlikely strictly structural details newly formed particle, we found high temperatures and/or...
Quartz crystal microbalances (QCMs) are devices that have been proven to function as sensors for detecting specific chemical species; this usually requires the QCM is modified with a material capable interact desired compound. Zeolites an example of materials used sensitive layer. This due their capacity selective adsorption and large surface area; moreover, they can grow directly on surface. After, interaction between layer analyte, there mass change surface, which induces frequency shift...
Iron inclusion in the composition of zeolite crystal structure endows it with new and useful properties. However, direct synthesis involving Fe, frequently creates unfavorable conditions that hinder crystallization process generate impurity phases. For this reason, novel methods, which include iron within zeolitic matrix, are being sought out. This article presents a one-pot iron-modified X. The resulting materials were characterized, their textural, electrical, magnetic properties studied.
Mesostructured pillared zeolite materials in the form of lamellar phases with a crystal structure mordenite (MOR) and ZSM-5 (MFI) were grown using CTAB as an agent that creates mesopores, one-pot synthesis; then into layers separating 2D plates introduced by diffusion TEOS molecules which further hydrolyzed, finally material was annealed to remove organic phase, leaving separated pillars silicon dioxide. To monitor successive structural changes state atoms framework compounds at all steps...
Functional materials that have a prominent place in high technology are not classified according to their origin (metals, ceramics, polymers, glass, etc.) or processing technology, but by the functions they can perform. Zeolites an interesting and important raw material for preparing variety of target substances. From traditional point view, aluminosilicate oxide with nanoporous structure. However, zeolites adsorbents, ion exchangers, catalysts, be used medicine, agriculture, construction...
COVID-19 has drawn worldwide attention to the need for personal protective equipment. Face masks can be transformed from passive filters into active protection. For this purpose, it is sufficient apply materials with oligodynamic effect fabric of masks, which makes possible destroy infectious agents that have fallen on mask aerosol droplets air stream. Zeolites themselves are not materials, but serve as carriers nanoparticles metals and/or compounds silver, zinc, copper, and other biocidal...
The use of sensors is a primary need in robotic systems. There are that generate signal whose frequency depends on input stimulus. application such desirable due to their short response time, accuracy, and resolution. For proper these sensors, adequate measurement required. principle rational approximations method for estimation has advantages over other methods. Some them include not fixed sampling insensitivity jitter, accuracy limited by the reference stability. Nevertheless, there some...
A comprehensive study of the catalytic properties copper-iron binary system supported on mordenite, depending iron valence—CuFe2MOR and CuFe3MOR—was carried out, redox ability has been considered as a decisive factor in determining efficiency. Acidity was studied by TPD-NH3, DRIFT-OH, DRT methods. The total acidity both samples high. Brönsted is similar for bimetallic explained zeolite; Lewis varies greatly depends exchange cations. screening DRIFT CO NO shown capacity demonstrated potential...
