Atmospheric particles with an aerodynamic diameter less than or equal to 2.5 micrometers (PM2.5) were collected at two sites located in the urban area of the city of Cuernavaca (Morelos) during a season when a large number of forest fires occurred. Three dicarboxylic acids (malonic, glutaric and succinic) and levoglucosan were analyzed by liquid chromatography coupled with mass spectrometry (ESI-Q-TOF) and soluble potassium (K+) was analyzed by ion chromatography. The concentration of PM2.5 increased on the days when the highest number of forest fires occurred. A strong correlation was observed between levoglucosan and K+, confirming the hypothesis that both are tracers of biomass burning (r = 0.57, p < 0.05). Levoglucosan (average 367.6 ng m−3, Site 2) was the most abundant compound, followed by succinic acid (average 101.7 ng m−3, Site 2), glutaric acid (average 63.2 ng m−3, Site 2), and malonic acid (average 46.9 ng m−3, Site 2), respectively. The ratio of C3/C4 concentrations ranged from 0.5 to 1.2, with an average of 0.8, which suggests great photochemical activity in the Cuernavaca atmosphere. The ratio of K+/levoglucosan concentrations (0.44) indicates that open fires are the main source of these tracers. The positive correlations between PM2.5 and levoglucosan and succinic and malonic acids suggest that such compounds are contributing to secondary organic aerosol particle formation.

This study focuses on the glow discharge generated with a gases mixture of Ethanol (C2H5OH) and Helium (He), at different concentrations maintained at a total pressure of 2.0 Torr. We used optical emission spectroscopy (OES) to analyze the discharge mixture at different concentrations of Helium. Single Langmuir probe data was used to determine the Electron Energy Distribution Function (EEDF). For the total C2H5OH/He mixture plasma concentrations, the EEDF has a Maxwellian distribution function. A decrease in He concentration results in significant changes in the EEDF, this behavior is related to the increase in the C2H5OH percentage must increase the energy loses of the electrons in the inelastic collision with C2H5OH producing a significant change in the EEDF, therefore, the EEDF pattern results in an increase of electron–molecule reaction rates. The rise in electron temperature for increasing Helium percentage is explained by the decreasing electron energy loss in the inelastic collisions with C2H5OH molecule. It observes a decrease of electron density ne as a function of the Helium percentage, which can be related to the ratio between ionization cross sections of Helium and C2H6O molecule. The active species are generated in the electron-molecule processes, which are associated with electron impact dissociation of C2H5OH and Helium electronic impact excitation in the gas phase. The emission optical spectra (OES) show changes in the intensity of the most important peaks of the plasma mixture, which indicates the dependence in the formation of the plasma as a function of the percentage of the gases. The changes in the intensities of the same observed species are due to different processes of excitation and ionization energies of the system, in addition to the increase of He metastable states He I. Hydrogen is the main product obtained from the decomposition of C2H5OH.

This work characterizes the degradation of the textile dye azo Acid Black 52 by measuring several physical and chemical parameters. A corona plasma was created at atmospheric pressure and applied on the liquid-air interface of water samples containing the dye. 1.0 mM of ferrous sulfate (FeSO4) was added to 1.0 mM dye solution, for a total volume of 250 mL. For each treatment, a number of parameters were quantified. These were voltage, current, temperature, loss of volume, pH, electrical conductivity, concentration, optical mission spectra, chemical oxygen demand (COD), total organic carbon (TOC), and the removal ratio. Because of the increase in the sample temperature, the volume lost by evaporation was explored. The results show that the efficiency of the dye degradation by plasma is a function of treatment time. Moreover, the reactive concentration of FeSO4 and the exposition time of the plasma were varied at a constant volume, leading to the determination of the concentrations and optimal times. Considering the degradation and removal parameters, at the maximum treated time of 80 min, it found that COD was of 96.36%, TOC of 93.93%, and the removal ratio of 97.47%.

The variations in the physical and chemical parameters involved in the degradation of dye Acid Black 52 (AB52) using plasma were analyzed. The plasma, or electrical discharge, was generated in the gas–liquid interface at atmospheric pressure using a dc power supply. The system configuration comprised two tungsten electrodes: the cathode is immersed in the solution while the anode is fixed above the surface with a gap of 5 mm, where the plasma is generated. The absorbance, total organic carbon, chemical oxygen demand, pH variation, electrical conductivity, optical emission spectrum, and the change in volume and temperature were measured for each sample as a function of treatment time.

Ethanol plasma produced in low pressure with constant flux has been characterized in situ by optical emission spectroscopy (OES) and a Langmuir probe. From these methods, hydrogen and carbon monoxide are the main products from the ethanol decomposition in the plasma. In addition, C2, OH, CH, O2+, and $\text{H}_{\alpha }$ species were identified. The values obtained for electron density and temperatures were $1.26 \times 10^{18}~\text{m}^{-3}$ and 1.16 eV, respectively. The mass deposited (MD) on the electrode was analyzed by scanning electron microscopy and Fourier transform infrared spectroscopy (FT-IR) techniques. The morphology of the MD changes as a function of the discharge time from thin film to a cluster formation. The FT-IR results show that the main absorbance corresponds with C–H bonds, indicating that the mass deposit is formed mainly by this molecular fraction, which agrees with the CH species identified as the less abundant molecule in the plasma by OES. In addition, $\text{C}\equiv \text{C}$ , O–H, C–H, C=C, and C–O bonds were identified.

The aim of this study was to obtain data on the biodistribution of (64)CuCl2 in rats and to obtain estimates of the radiation doses to humans by extrapolating the animal data. MicroPET imaging and biodistribution studies were carried out with Wistar rats, and the doses were estimated with OLINDA/EXM. The lower large intestine wall was found to be the critical organ with an absorbed dose of 139±34 and 125±32µGy/MBq for females and males, respectively. The corresponding effective doses were estimated as 47±4 and 39±4µSv/MBq.

In this paper, the addition of Ar to H 2 is experimentally investigated. This paper primarily aims to observe the effects that this addition has on the intensity of hydrogen emission lines in a glow discharge mixture. The total pressure was 3 torr, at a power level of 3.9 W. Optical emission spectroscopy was used for plasma characterization, and the principal species observed were H γ (434 nm), H β (486.1 nm), H α (656.3 nm), and H 2 (603.1 nm), and Ar I (750.5 nm), Ar I (763.5 nm), and Ar I (811.6 nm). The electron temperature and ion density were determined by a double Langmuir probe. The electron temperature was found to be in the range of 2.5-6.5 eV, and the ion concentration was on the order of 109 cm -3 .

A DC glow discharge produced in N2 gas can generate several species that are important in different applications, such as the modification of surface properties of materials. A low-pressure glow discharge apparatus was used for the the analysis of the Ar–N2 mixture at a total pressure of 2.0 Torr, a power of 20 W and 40 l/min flow rate of gases. The emission bands were measured in the wavelength range of 200–1100 nm. The principal elements are N2, N 2+ and Ar I. The electron temperature was found in the range of 1.72–2.08 eV, and the ion density was in the order of 1010 cm−3.
