In this study, chlorapatite (ClAp) samples co-doped with Fe and Ni at different amounts were synthesized using a wet chemical method. The as-produced samples were immersed in simulated body fluid (SBF) for 14 and 28 days. The samples were characterized before and after soaking in SBF, and their morphologies and structural properties were compared to each other. It was observed that the immersion period in SBF and the amount of Fe and Ni affected the morphology and structural properties of the ClAp samples.

A validated isocratic method utilizing reverse-phase high-performance liquid chromatography (RP-HPLC) was developed for the quantification of hydroxymethylfurfural (HMF) in five distinct commercially available Dulce de Leche samples that are sold in Turkish markets. The X-Terra RP-18 column, which has dimensions of 150 × 4.60 mm i.d. and a particle size of 5 μm, was selected for the stationary phase. The separation process was conducted isocratically by utilizing a methanol-water mixture (10:90, v/v) containing 1% TCA as the mobile phase. The separation was carried out at a temperature of 25 oC and a flow rate of 0.5 mL/min. The detection was performed at a wavelength of 284 nm. The methodology exhibited favorable selectivity and linearity, as evidenced by a correlation coefficient (r) exceeding 0.999. The obtained values for the limit of detection (LOD) and limit of quantification (LOQ) were 0.0019 μg/mL and 0.0059 μg/mL, respectively. Additionally, the recovery rate was determined to be 95.45%. Furthermore, it has been reported that the levels of HMF in commercially available Dulce de Leche originating from Turkey vary between 50.55 and 90.18 mg/kg for the total HMF content.

Ni-Mn-Sn-based Heusler alloys are important materials that have potential applications as environmentally friendly smart materials with beneficial properties as well as being magnetic. Both the magnetic field-induced reverse martensitic transformation and the high operating temperature are crucial for the applications of Ni-Mn-Sn-based magnetic shape memory alloys. In this study, martensite transformation temperatures were determined by applying different heat treatments (700 °C, 900 °C, 1100 °C) to Ni45Mn40Sn10Cu5 sample produced by Arc Melter melting method. While reverse conversion was observed in T2 (no heat treatment) and 700°C heat treatment, no reverse conversion was observed at 900°C and 1100°C. When the X-ray diffractogram was examined, martensite phase and γ phase were determined. When the magnetic hysteresis of the samples was examined, it was observed that the magnetic saturation went towards zero with the increase in heat treatment and accordingly, there was a decrease in the magnetization effect.

ABSTRACT Computing research on aspirin has produced considerable knowledge of its molecular structure and actions. It has revealed its chemical characteristics and connections with other molecules. Data from the study will be used to further investigate the effects of the drug and potential new uses for it. Using Density Functional Theory (B3LYP/cc-pVDZ) computations, we analyzed the optimal molecular shape, vibrational frequencies, 1H- and 13C-NMR chemical shifts. We also investigated electronic structural factors, such as dipole moment (μ), hardness (η), softness (σ), electronegativity (χ), electrophilicity index (ω), nucleophilicity index (ε), and chemical potential (Pi), which are connected to corrosion inhibition efficacy. Additionally, we calculated the fraction of transferred electrons (ΔN) to determine the interaction between the iron surface and organic molecules. The calculations revealed a positive association between organic-based corrosion inhibitors and quantum chemical parameters processes. Thus, the behavior of corrosion inhibitors can be predicted without the need for experimental investigation.

Radon is a noble gas that has a high risk to the human body, and existence at various rates in soil, air and different source of water. Moreover, radon has a short lifetime but it can produce more risk to public health. Humans are good users of water by food, drinking water, vegetable, shower and dishwashing, however, we do have not good knowledge about the risk of radon, and we need to do more research because it’s one of the main factors to various types of cancer such as lung and stomach cancer. This review used different data in some research in different countries (Romania, Chania, Brazil, Sudan, India, Syria, Iraq, and Yemen) in (2012-2020) with the help of the RAD7 detector because it has higher resolution and is faster in measurement. In current review, higher average reading of radon was found in Nigeria, its reading was (36.1 Bq/L) which was more than the standard value in the world for drinking water (11.1 Bq/L). In any country there are so many factors to high and low concentration of radon in drinking water which are discussed and explained in this review.

Polarized lenses are recommended because exposure to intense sunlight damages cellular function and photoreceptor structures in the eyes. Polarized lenses filter all wavelengths of UV radiation and most of the reflected glare due to strong reflections depending on the angle of incidence of sunlight and environmental factors. The wavelength of mineral glass in the horizontal and vertical direction (~550nm) is 16.64% for (CF1) and 13.21% for (CF2). There is a sudden drop of 27.87 at 729nm in CF2 and a sudden increase to 58.80 at 730nm in CF1. Absorbance values at 730nm are 0.21 with a decrease in AF1 and 0.54 with an increase in AF2. CF2 is polarized. To determine how the structure of the lens material affects light transmittance and absorbance, the light transmittances of smoked mineral and organic lenses of the same color are 16.64 for the mineral lens and 22.47 for the organic lens at (~550nm) wavelength. Maximum transmittance is 81.25 for mineral lens and 85.73 for organic lens. For night vision, at (~507nm) wavelength, it is 19.35 for mineral lens and 25.00 for organic lens. At (~550nm) wavelength, absorbance values are 0.78 for mineral lens and 0.62 for organic smoked lens. In the study, the effect of color factor on the light transmittance and absorption of organic smoked, brown and green polarized lenses was investigated. Light transmittance at 550 nm wavelength is 22.47 in smoked, 13.48 in brown and 14.32 in green. Absorbance at 550 nm wavelength is 0.62 in smoked, 0.94 in brown and 0.82 in green lens. Since dark lenses do not allow high light transmission, smoked color should be chosen for good vision in the visible light region. Brown color should be preferred if dark glasses should be used in situations where bright light is intense. In the 507nm wavelength of color polarized lenses, smoked is 25.00, brown is 11.45 and green is 16.94. Smoked should be chosen for night vision.

The optical properties of the prescription and non-prescription (plano) samples of the MR-8 high index lens were examined by UV/VIS spectrometry. The results showed that the light transmittance of the two MR-8 lens samples examined was over 90%, and the transmittance at the wavelength (~550nm) to which the human eye is most sensitive was 83.437% and 84.602% for the prescription and non-prescription samples, respectively. In terms of quality of vision, it is expected that the visible light transmittance will be high and the ultraviolet light transmittance will be minimal. It is very important that both the prescription and non-prescription organic MR-8 lenses tested have no transmittance below approximately 398nm. This means that this lens material protects against UVA and UVB rays, even though it is uncoated. It is also important to reduce the dose to the lens, which is a radiosensitive tissue. In the study, the mass absorption coefficients of MR-8 and Ormix lens materials in the 0.15-2.00 MeV energy range were calculated using the web-based XCOM programme. LAC, HVL, TVL, MFP, RPE and TF values were calculated from the MAC values obtained. At energies below 0.05 MeV, the maximum MAC value was 0.974 and 4.416 for the MR-8 and Ormix lenses, respectively. The RPE and TF values were 0.807-16.235%, 0.996-0.992% for the MR-8 lens and 0.862-55.233%, 0.448-0.991% for the Ormix lens. The results showed that the photon absorption ability of the Ormix lens is relatively better in the region where the photoelectric interaction is dominant. This research is also important in terms of determining the optical and nuclear radiation parameters of the material used in the manufacture of high index lenses and investigating its effectiveness in reducing the dose to the eyepiece.

This research is also important in terms of determining the optical and nuclear radiation parameters of the material used in the manufacture of high index lenses and investigating its effectiveness in reducing the dose to the eyepiece.","PeriodicalId":196782,"journal":{"name":"Journal of Physical Chemistry and Functional Materials","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139350410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research focused on investigating and optimizing the interaction of the hormone Norepinephrine (Noradrenaline), which acts as a neurotransmitter, with Mg+2 atoms at the molecular level. To do this, we used GaussView 6.0.16 to generate the molecular structure. Then, it employed Gaussian 09: AS64L-G09RevD.01 program to optimize the molecular structures of Norepinephrine using the DFT method and SDD basis set, and the Mg atom doped molecule using the DFT method and LanL2MB basis set. Various quantum mechanical calculations were conducted on the molecule, including Fourier Transform Infrared spectroscopy (FT-IR), Nuclear Magnetic Resonance Spectroscopy (NMR), HOMO-LUMO structure with the energy level diagram, UV-visible absorption, and density of states (DOS). These calculations provide important insights into the behavior and properties of the Norepinephrine-Mg+2 complex at the molecular level.
