Cysteine-protected metal nanoparticles (NPs) have shown interesting physicochemical properties of potential utility in biomedical applications and the understanding protein folding. Herein, cysteine interaction with gold, silver, copper NPs is characterized by Raman spectroscopy density functional theory calculations to elucidate molecular conformation adsorption sites for each metal. The experimental analysis spectra upon respect free indicates that while C–S bond carboxyl group are...
Abstract Gold, silver, and copper small nanoparticles (NPs), with average size ≈ 2 nm, are synthesized afterward protected l ‐ d ‐cysteine, demonstrating emergence of chiroptical activity in the wavelength range 250–400 nm for all three metals respect to bare ligands alone. Silver‐cysteine (Ag‐Cys) NPs display higher anisotropy factor, whereas gold‐cysteine (Au‐Cys) show optical signatures slightly more displaced visible range. A larger number circular dichroism (CD) bands smaller intensity,...
We present an extensive first-principles time-dependent density-functional theory study of the optical response small (M/M′)6 and (M)3(M′)3 six-atom clusters (unary equimolar binary hexamers group IB metals: Cu, Ag, Au), both in gas-phase supported on MgO(100) surface, chosen as a model simple oxide substrate. UV–vis spectra are predicted analyzed detail terms ground- excited-state wave functions involved Kohn–Sham orbitals, to rationalize origin features absorption these systems. The...
Abstract The use of concentrated solar energy in processing ceramic materials is an attractive route to obtain these with low CO 2 emissions. In this work, nanostructures monoclinic zirconia (m-ZrO ) were obtained using provided by the IER-UNAM furnace as a heat source. first stage process, Zr/O/C complex was sol-gel method at temperature 120 °C zirconium n-propoxide and sorbitol precursors reagents. This used second m-ZrO heating it 1200 for one hour air atmosphere. last performed furnace....
Glutathione (GSH) is the most abundant low-molecular-mass thiolated compound in plants and animals. It has a very flexible conformation undergoes structural charge changes depending on pH. GSH highly relevant humans as it one of principal antioxidant agents capable scavenging reactive oxygen species (ROS). Recently, was discovered that works against COVID-19. In addition, function immune system cell proliferation. To further understand mechanisms glutathione, density functional theory (DFT)...
