Complementarity between fluorescence and reflection in photoluminescent cholesteric liquid crystal devices was written by Kim, Jang-Kyum;Joo, Suk-Hwan;Song, Jang-Kun. And the article was included in Optics Express in 2013.SDS of cas: 7128-64-5 This article mentions the following:

The combination of photoluminescence (PL) and cholesteric liquid crystal (CLC) provides interesting complementary features for an optimized display application. Distortion of the Bragg lattice of CLCs decreases selective reflection but increases fluorescence intensity; recovery of a uniform lattice in turn results in increased reflection and decreased fluorescence. This complementary relationship between the fluorescence and the Bragg reflection gives rise to self-compensations for color shifts due to either dynamic slow response of CLC helix or mismatch of oblique incidence of light with respect to the helical axis. These color shifts have long been intrinsic unsolved limitations of conventional CLC devices. Thus, the complementary coupling between the fluorescence and the CLC Bragg reflections plays an important role in improving the color performance and the quality of moving images. In the experiment, the researchers used many compounds, for example, 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5SDS of cas: 7128-64-5).

Identifying chondroprotective diet-derived bioactives and investigating their synergism was written by Davidson, Rose K.;Green, Jonathan;Gardner, Sarah;Bao, Yongping;Cassidy, Aedin;Clark, Ian M.. And the article was included in Scientific Reports in 2018.SDS of cas: 7128-64-5 This article mentions the following:

Osteoarthritis (OA) is a multifactorial disease and nutrition is a modifiable factor that may contribute to disease onset or progression. A detailed understanding of mechanisms through which diet-derived bioactive mols. function and interact in OA is needed. We profiled 96 diet-derived, mainly plant-based bioactives using an in vitro model in chondrocytes, selecting four candidates for further study. We aimed to determine synergistic interactions between bioactives that affected the expression of key genes in OA. Selected bioactives, sulforaphane, apigenin, isoliquiritigenin and luteolin, inhibited one or more interleukin-1-induced metalloproteinases implicated in OA (MMP1, MMP13, ADAMTS4, ADAMTS5). Isoliquiritigenin and luteolin showed reactive oxygen species scavenging activity in chondrocytes whereas sulforaphane had no effect and apigenin showed only a weak trend. Sulforaphane inhibited the IL-1/NFκB and Wnt3a/TCF/Lef pathways and increased TGFβ/Smad2/3 and BMP6/Smad1/5/8 signalling. Apigenin showed potent inhibition of the IL-1/NFκB and TGFβ/Smad2/3 pathways, whereas luteolin showed only weak inhibition of the IL-1/NFκB pathway. All four bioactives inhibited cytokine-induced aggrecan loss from cartilage tissue explants. The combination of sulforaphane and isoliquiritigenin was synergistic for inhibiting MMP13 gene expression in chondrocytes.

Development and validation of an HPLC method with fluorescence detection for the determination of fluorescent whitening agents migrating from plastic beverage cups was written by Alberto Lopes, Joao F.;Tsochatzis, Emmanouil D.;Emons, Hendrik;Hoekstra, Eddo. And the article was included in Food Additives & Contaminants, Part A in 2018.Application of 7128-64-5 This article mentions the following:

An HPLC method with fluorescence detection has been developed and validated for the quantification of six fluorescent whitening agents (FWA) in plastic beverage cups after extraction and in food simulants after migration at 70°C for 2 h. The sensitivity of the method was high with LODs ranging from 0.053 to 0.251 μg kg^-1 and LOQs from 0.107 to 0.504 μg kg^-1. Accuracy and precision were highly acceptable, with recoveries greater than 82% and RSDs (%) below 16%. The expanded combined uncertainty was found to be less than 23% for the measurements of all studied FWAs. In extracting the analytes from food contact materials (FCM), accelerated solvent extraction (ASE) and Soxhlet extraction were applied using ethanol as the extraction solvent. The results obtained for FWA in 10 different food plastic cups, made from different polymers, were compared. The ASE technique proved to be faster, more effective and efficient than Soxhlet extraction Migration tests with official food simulants from Regulation (EU) No 10/2011 showed that the substances studied could potentially migrate using the selected migration conditions. The most pronounced effect was observed in case of simulant D1 (50% w/v ethanol in water). The anal. method proved to be a simple, fast, sensitive and reliable tool for the simultaneous quantification of six of the most used FWAs in both FCM extracts and food simulants after migration experiments In the experiment, the researchers used many compounds, for example, 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5Application of 7128-64-5).

And the article was included in Plasma Processes and Polymers in 2014.Quality Control of 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene This article mentions the following:

This paper reports on the incorporation of three com. fluorescent dyes, i.e., rhodamine 6G, fluorescein, and fluorescent brightener 184, in plasma coatings, by utilizing a dielec. barrier discharge (DBD) reactor, and the subsequent monitoring of the coatings homogeneity based on the emitted fluorescent light. The plasma coatings are qual. characterized with fluorescence microscopy, UV-vis spectroscopy and profilometry for the determination of the coating thickness. The emitted fluorescent light of the coating correlates to the amount of dye per area, and deviations of these factors can hence be observed by monitoring the intensity of this light. This allows monitoring the homogeneity of the plasma coatings in a fast and simple way, without making major adjustments to the process.

Simultaneous determination of fluorescent whitening agents (FWAs) and photoinitiators (PIs) in food packaging coated paper products by the UPLC-MS/MS method using ESI positive and negative switching modes was written by Wu, Zhijiang;Xu, Yansheng;Li, Mianchang;Guo, Xindong;Xian, Yanping;Dong, Hao. And the article was included in Analytical Methods in 2016.Application of 7128-64-5 This article mentions the following:

A sensitive ultra-high performance liquid chromatog. tandem mass spectrometry (UPLC-MS/MS) method was established for the simultaneous determination of fluorescent whitening agents (FWAs) and photoinitiators (PIs) in food packaging coated paper products. Samples were firstly soaked in water and then ultrasonically extracted by using methanol-trichloromethane. The extraction solution was subsequently separated by using a Phenomenex Luna C18 (2) chromatog. column (50 mm × 2.00 mm, 3 μm) using methanol-5 mmol L^-1 ammonium acetate as the mobile phase. The target analytes were ionized by the ESI pos. and neg. switching modes and detected using the multiple-reaction monitoring (MRM) mode. The method was validated for linearity and range, accuracy, precision and sensitivity. Under the optimized conditions, the calibration curves were linear over the selected concentration ranges of 10-1000 μg L^-1 and 0.5-50 μg L^-1 for four FWAs (FWA28, FWA85, FWA71 and FWA351) and the rest of the ten compounds, resp., with calculated coefficients of determination (R²) greater than 0.99. The instrument limit of quantitation (ILOQ) and the corresponding method limit of quantitation (MLOQ) of fourteen target analytes were in the range of 0.5-10 μg L^-1 and 6-125 μg kg^-1, resp. Recoveries were calculated at three levels of concentration spiked into neg. samples and the values were found between 79.2% and 115% with relative standard deviation (RSD) values of 3.2-12.3% for intra-day precision (n = 6) and 4.5-11.5% for inter-day precision (n = 5) 2.5-7.2%. The method was successfully applied to analyze twenty-five food packaging coated paper product samples and FWA184 and 4-MBP were detected in only two samples with the concentrations of 151 μg kg^-1 and 32 μg kg^-1, resp. In the experiment, the researchers used many compounds, for example, 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5Application of 7128-64-5).

A new kind of blue hybrid electroluminescent device was written by Wang, Junling;Li, Zhuan;Liu, Chunmei. And the article was included in Journal of Nanoscience and Nanotechnology in 2016.COA of Formula: C26H26N2O2S This article mentions the following:

Bright blue Electroluminescence come from an ITO/BBOT doped silica (6 × 10^-3 M) made by a sol-gel method/Al driven by AC with 500 Hz at different voltages and Gaussian anal. under 55 V showed that blue emission coincidenced with typical triple emission from BBOT. This kind of device take advantage of organics (BBOT) and inorganics (silica). Electroluminescence from a single-layered sandwiched device consisting of blue fluorescent dye 2,5-bis (5-tert-butyl-2-benzoxazolyl) thiophene (BBOT) doped silica made by sol-gel method was investigated. A number of concentrations of hybrid devices were prepared and the maximum concentration was 6 × 10^-3 M. Blue electroluminescent (EL) always occurred above a threshold field 8.57 × 10⁵ V/cm (30 V) at alternating voltage at 500 HZ. The luminance of the devices increased with the concentration of doped BBOT, but electroluminescence characteristics were different from a single mol.’s photoluminescence properties of triple peaks. When analyzing in detail direct-current electroluminescence devices of pure BBOT, a single peak centered at 2.82 eV appeared with the driven voltage increase, which is similar to the hybrid devices. Comparing Gaussian decomposition date between two kinds of devices, the triple peak characteristic of BBOT was consistent. It is inferred that BBOT contributed EL of the hybrid devices mainly and silica may account for a very small part. Meanwhile the thermal stability of matrix silica was measured by Thermal Gravity-Mass Spectroscopy (TG-MS). There is 12 percent weight loss from room temperature to 1000 °C and silica has about 95% transmittance. So the matric silica played an important role in thermal stability and optical stability for BBOT. In addition, this kind of blue electroluminescence device can take advantages of organic materials BBOT and inorganic materials silica. This is a promising way to enrich EL devices, especially enriching inorganic EL color at a low cost.

Effect of surface wettability on the interfacial adhesion of a thermosetting elastomer on glass was written by Wang, Ye;Hansen, Christopher J.;Wu, Chi-Chin;Robinette, E. Jason;Peterson, Amy M.. And the article was included in RSC Advances in 2021.Product Details of 7128-64-5 This article mentions the following:

Interfacial adhesion dictates properties and performance of both composites and adhesively bonded structures. Weak adhesion at the interfaces of polymer composites leads to void formation and debonding, which adversely affect composite structural integrity and mech. performance. This work investigated the relationship between surface wettability and interfacial fracture energy with the goal of tailoring interfacial adhesion within polymer composites. A series of model functionalized surfaces was created using silane coupling agents with different organo-functionalities to alter surface wettability. Based on the anal. of interfacial fracture energy between a thermosetting elastomeric polymer network and model surfaces, interfacial adhesion was found to be pos. correlated to resin wettability. The results provide a fast and simple approach to screen different material combinations for the development of novel polymeric composites and adhesively bonded structures with tailorable adhesion.
