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.","PeriodicalId":196782,"journal":{"name":"Journal of Physical Chemistry and Functional Materials","volume":"175 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139212261","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}

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.","PeriodicalId":196782,"journal":{"name":"Journal of Physical Chemistry and Functional Materials","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322586","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 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.","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}
