Abstract:

This study presents the spectral characterization of TiO2 nanoparticles (NPs) functionalized with three porphyrin derivatives: 5,10,15,20-(Tetra-4-aminophenyl) porphyrin (TAPP), 5,10,15,20-(Tetra-4-methoxyphenyl) porphyrin (TMPP), and 5,10,15,20-(Tetra-4-carboxyphenyl) porphyrin (TCPP). UV-Vis absorption and Fourier transform infrared spectroscopy–attenuated total reflection (FTIR-ATR) spectroscopic studies of these porphyrins and their complexes with TiO2 NPs were performed. In addition, the efficiency of singlet oxygen generation, the key species in photodynamic therapy, was investigated. UV

Abstract:

The depth-profiles of accelerated aged triterpenoid dammar and mastic varnishes, which had been uncovered by optimized KrF excimer laser ablation (248 nm, 25 ns), were examined by ultraviolet–visible (UV/VIS) spectrophotometry and attenuated total reflection (ATR) Fourier transform infrared (FT-IR) spectroscopy. The results reflect both the optical properties at the bulk (UV/VIS) and the surface (ATR/FT-IR) and establish the presence of degradation gradients across the depth of the degraded natural resin films. It is demonstrated that the UV part of the ambient radiation is absorbed by the det

Abstract:

The non-alternant hydrocarbon cyclopenta[1,2-a : 3,4,5-b′c′]dicoronene (3) has been prepared by aluminium chloride catalyzed dimerization of coronene (1). The UV/VIS absorption spectrum, fluorescence spectrum and fluorescence quantum yield of 3 is reported and compared with that of the alternant isomer benzo[1,2,3-bc:4,5,6-b′c′]dicoronene (2). Relationships observed in the UV/VIS absorption spectra of alternant and non-alternant polycyclic aromatic hydrocarbons and preliminary theoretical investigations (PMO calculations) on two model systems (C, E) are also reported.

Their structure was resolved on the basis of spectroscopic investigations (1H NMR, IR, UV-VIS). Catalytic activity of these complexes in olefin metathesis reaction was also examined.The electronic structure of dinitrosyl-molybdenum complexes with ligands coordinating by oxygen atoms was calculated for the example of the di- and tetra-acetato-dinitrosyl-molybdenum complexes using the Fenske-Hall and INDO methods.

Abstract:

Polystyrene is an electron-rich polymer wherein the electrons ejected on irradiation are localized and could be investigated by using spectroscopic methods. Pre-irradiated, PTPC (Pre-irradiated Tarsons Polystyrene Control) were irradiated with a cumulative dose of γ-rays 51, 77 and 129 kGy at 300-308 K referred to as RTPS (Re-irradiated Tarsons Polystyrene Samples). These RTPS were subjected to different post-irradiation treatments and were analyzed by UV-Vis absorption spectrometry. The regions 300 – 400 and 600 – 900 nm show differential absorption in RTPS in dose dose-dependent manner. The

Abstract:

An easy and efficient synthetic methodology for two hitherto unknown tropylium-cation-fused Hückel aromatic [26] dicarbaporphyrinoids has been developed by acid-catalyzed Lindsey type condensation of bithiophene/biselenophene diol with azulene using BF3 · Et2O followed by oxidation with chloranil and/or DDQ. Both the macrocycles have been achieved in moderately good yields. Their structures, aromaticity and optical properties have been elucidated by NMR, UV-vis-NIR spectroscopic analyses and in-depth theoretical calculations. Both the macrocycles exhibited strongly diatropic characteristics wi

Abstract:

Titanium dioxide thin coatings are widely used in different fields for the manufacture of various products:electrochromic displays, photocatalytic systems, photosensitized solar cells and many others. At the same time, the possibilities for obtaining protective coatings based on TiO2 are of interest. The chemical and physical characteristics of the TiO2 coatings depend on a large extent of the applied technological method and the temperature values of the heat treatment used. Coatings are prepared by sol gel method applying dip coating technique. The present study characterizes self-cleaning T

Abstract:

In the previous chapter, we developed a set of conceptual and mathematical tools for analyzing the models and experimental data that form the subject matter of nonlinear chemical dynamics. Here, we describe some of the key items of experimental apparatus used to obtain these data so that the reader can better appreciate the results discussed in the following chapters and can learn how to begin his or her own investigations. The first several sections are devoted to measurements of temporal behavior, with emphasis on the techniques used to monitor reactions in time and on the reactors in which
