Effect of high-pressure/temperature (HP/T) treatments of in-package food on additive migration from conventional and bio-sourced materials was written by Mauricio-Iglesias, M.;Jansana, S.;Peyron, S.;Gontard, N.;Guillard, V.. And the article was included in Food Additives & Contaminants, Part A in 2009.Computed Properties of C26H26N2O2S This article mentions the following:

Migration was assessed during and after two high-pressure/temperature (HP/T) treatments intended for a pasteurization (800 MPa for 5 min, from 20 to 40°C) and a sterilization treatment (800 MPa for 5 min, from 90 to 115°C) and were compared with conventional pasteurization and sterilization, resp. The specific migration of actual packaging additives used as antioxidants and UV light absorbers (Irganox 1076, Uvitex OB) was investigated in a number of food-packaging systems combining one synthetic common packaging (LLDPE) and a bio-sourced one (PLA) in contact with the four food-simulating liquids defined by European Commission regulations. After standard HP/T processing, migration kinetics was followed during the service life of the packaging material using Fourier transform IR spectrometer (FTIR) spectroscopy. LLDPE withstood the high-pressure sterilization, whereas it melted during the conventional sterilization. No difference was observed on migration from LLDPE for both treatments. In the case of PLA, migration of Uvitex OB was very low or not detectable for all the cases studied. In the experiment, the researchers used many compounds, for example, 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5Computed Properties of C26H26N2O2S).

Programmable, UV-printable dielectric elastomers actuate at low voltage without prestretch and supporting frames was written by Borayek, Ramadan;Zhang, Pengpeng;Willy, Habimana J.;Zedan, Mostafa;Zhu, Jian;Ding, Jun. And the article was included in ACS Applied Electronic Materials in 2020.Application In Synthesis of 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene This article mentions the following:

Dielec. elastomers are soft and perfect insulator polymers able to produce large strains with high energy d. under the effect of applied high voltage. However, their use in practical applications is hindered by the need for high voltage to actuate. Also, they need prestretching between rigid frames to produce out-of-plane shape changes, which may reduce their lifetime. Here, we synthesized a set of elastomers with high permittivity (from 20 to reach 60 at 10³ Hz), controllable thermal properties (T_g vary from -15 to -50°), and good mech. properties (Young’s modulus values between 0.48 and 0.2 MPa at 20% strain). Due to the high permittivity, an actuator made of the material was able to respond to a low voltage of 700 V and produce a 6.5% area strain for more than 10,000 cycles. Moreover, the elastomers were found to produce giant free-end bending displacements with prespecified bending direction (bend to the side of the pos. electrode) under a low elec. field, which we called programmable dielec. elastomers (PDE). Besides the aforementioned characteristics and performance, the formulated elastomers are suitable for UV-based three-dimensional (3D) printing. The printability of the elastomers allows fabricating programmable complex geometries to produce high deformations under relatively low elec. fields. 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 In Synthesis of 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene).

Detection and characterization of extractables in food packaging materials by GC-MS was written by Humston-Fulmer, Elizabeth M.;Binkley, Joe. And the article was included in LC-GC Europe in 2017.Computed Properties of C26H26N2O2S This article mentions the following:

Migration or leaching of analytes from packaging material is a concern for manufacturers and con- sumers because of the potential contamination of food and beverages. This leaching can impact the quality of the product, affect the integrity of the packaging material, and cause concern related to consumer health and product safety. To investigate analytes with the potential for leaching, an extrac- tion of a variety of food packaging or storage products, including sealable plastic bags and plastic food containers, was performed. Solvent was placed inside each packaging product for an extended period of time and then concentrated through evaporation before anal. General screening of this extract with nontargeted anal. techniques was used to understand what analytes were extracted and may have the potential to leach into the food. Gas chromatog. (GC) was used for separating analytes from each other and time-of-flight mass spectrometry (TOF-MS) provided full mass range spectral data. Nominal-mass TOF-MS data were acquired and searched against library databases for tentative identifications. High-resolution TOF-MS data were also acquired to add confidence to identi- fications with accurate mass information. Several analytes were determined and are highlighted here.

Electrically Controlled Lasing in Supercooled Liquid Crystal Blue Phase I Microdroplets was written by Petriashvili, Gia;Hamdi, Ridha;Chanishvili, Andro;Zurabishvili, Tsisana;Chubinidze, Ketevan;Ponjavidze, Nino. And the article was included in ACS Applied Electronic Materials in 2020.Reference of 7128-64-5 This article mentions the following:

We have prepared the liquid crystal blue phase (BP) microdroplets emulsified in the glycerol environment and investigated their electro-optical properties upon the applied elec. field. We showed that the lasing from the supercooled luminescent dye-doped BPI microdroplets can be controlled elec. When the elec. field intensity is increased, the lasing intensity is increased too along with the linewidth that decreases from 6 to 2.5 nm. Besides, the laser lines were shifted toward the shorter wavelength by 11 nm. All effects were achieved via elec. field-stimulated structural and sym. modification of BPI microdroplets, resulting in their optical anisotropy and birefringence. Luminescent dye-doped liquid crystal blue phase-based microdroplets can find applications as elec. controlled microlaser sources for microphotonics and environmental sensing.

And the article was included in International Journal of Electrochemical Science in 2015.Computed Properties of C26H26N2O2S This article mentions the following:

A nickel(II) selective all-solid-state PVC membrane sensor (ASS-PMS) has been designed and constructed for the monitoring of nanomolar nickel(II) concentrations in various samples. The applicability of the sensor to real samples was proved through its use for the anal. of the target ion in waste water samples. The all solid state support and transducer was build through coating a nickel wire with a composite of graphite powder and an epoxy resin, and next it was coated with a nickel selective PVC membrane, with the optimal composition of 33% of PVC, 57% of Nitrobenzene, 2% RTIL (1-n-butyl-3-methylimidazolium hexafluorophosphate), 3% of KpClTPB, and 5% of ionophore L. The potential response of the ASS-PMS change with the concentration of the target ion at a slope of 29.5 ± 0.3 mV/decade, which is indicative of a Nernstian behavior, and was linear in the concentration range of 1.0 × 10-8 to 1.0 × 10-3 mol L-1 of the nickel(II), reaching a lower detection limit as low as 5.0 × 10-9 mol L-1. The response of the ASS-PMS was found to be almost independent from interference from different conventional ionic species. The ASS-PMS was successfully applied to the potentiometric determination of nickel(II) concentrations in ions electroplating waste water samples.

Digital Light Processing of Highly Filled Polymer Composites with Interface-Mediated Mechanical Properties was written by Wang, Ye;Delarue, Antoine P.;McAninch, Ian M.;Hansen, Christopher J.;Robinette, E. Jason;Peterson, Amy M.. And the article was included in ACS Applied Polymer Materials in 2022.Recommanded Product: 7128-64-5 This article mentions the following:

Digital light processing (DLP) is a popular method of additive manufacturing of thermosetting polymer composites with high resolution While DLP of composite systems has been demonstrated, only a few studies comment on the role of interfacial interactions on resulting mech. properties. In this work, high volume fraction (50 volume %) glass microsphere-reinforced composites were fabricated via DLP. The effects of surface chem. and interfacial interactions on the mech. and thermal properties of additively manufactured composites were investigated. Interfacial interactions between the urethane acrylate-based resin system and glass microspheres were found to dictate the overall performance of the composites. Greater resin-glass wettability led to simultaneous and anomalous increases in stiffness, toughness, and strength. Interestingly, composites where glass was functionalized to covalently bond with the resin phase only showed moderate improvements in mech. properties as compared to systems with high resin-glass wettability. Finally, complex structures with fine details were printed to demonstrate printability. In the experiment, the researchers used many compounds, for example, 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5Recommanded Product: 7128-64-5).

A simple and sensitive method has been developed for the simultaneous determination of five fluorescent whitening agents (FWA135, FWA184, FWA367, FWA368 and FWA393) in foam plastic tableware using high performance liquid chromatog. tandem mass spectrometry (HPLC-MS/MS). The samples were extracted with trichloromethane, and the polymer in the extracts were precipitated by adding methanol. The separation of five FWAs was carried out on a Phenomenex kinetex C₁₈ column (2.1 mm × 100 mm, 2.6 μm) by gradient elution with 0.1% formic acid methanol and 0.1% formic acid as mobile phase. Electrospray ionization mass was operated in the pos. mode (ESI⁺) using multiple reaction monitoring (MRM) for the qual. and quant. anal. of five FWAby retention time and ion ratio. The result indicated that the linear correlation coefficients (r > 0.995) of five FWAs were obtained with the linear relationship between 0.5 to 50 μg/L. The limits of detection (ILOD, S/N = 3) were ranged from 0.1 μg/L to 0.5 μg/L, and the limits of qualification of the method (MLOQ, S/N = 10) were varied from 0.4 μg/kg to 2.0 μg/kg.
