Single-use technologies are increasingly used in biopharmaceutical manufacturing Despite their advantages, these plastic assemblies draw concern because they are a potential source of contamination due to extractable and leachable compounds (E&Ls). Characterizing E&Ls from such materials is a necessary step in establishing their suitability for use. Therefore, there is an urgent need for sensitive methods to identify and quant. assess compounds in plastic materials. Accelerated solvent extraction (ASE) is a powerful technique that can be reliably used for this purpose. In this study, ASE followed by liquid chromatog. and Orbitrap-based High Resolution Accurate Mass (HRAM) mass anal. was found to be an efficient and versatile method for the determination of additives in different multilayer polymer systems from single-use bags. ASE optimization was performed using a design of experiments approach. The type of solvent, temperature, swelling agent addition, static time and number of cycles were the selected variables. Optimum conditions were dependent on the type of plastic film. Et acetate and cyclohexane were selected individually as optimum solvents. Optimum temperatures were 90-100°C. Pressure was set at 1500 psi and extraction time was 30 min in 2 cycles. Swelling agent addition was necessary with polar extraction solvents. More than 100 additives and degradation products were confidently identified by HRAM MS. Correlations between the type and levels of identified additives and the type of polymer system were established. In addition, degradation behavior and pathways for some additives can be addressed.

Higgins, Clare L. published the artcileSynthesis, characterisation, and performance evaluation of tri-armed phenolic antioxidants, Product Details of C9H21NO3, the publication is Tetrahedron Letters (2020), 61(28), 152127, database is CAplus.

In this study, a series of core units (glycerol, triethanolamine and triisopropanolamine derivatives) were investigated for their use in tri-armed phenolic antioxidants. The antioxidant ability of these tri-armed phenolic compounds featuring different core units were then evaluated in a hydrocarbon lubricant using differential scanning calorimetry (DSC) and compared to the com. available antioxidants Irganox L135 and Irganox L57. An impressive oxidation induction time of ∼9-12 min was observed for the glycerol based antioxidants when compared to the com. antioxidants (∼4-6 min), whereas in contrast in the case of triethanolamine and triisopropanolamine derived antioxidants, a solubilizing unit was incorporated to provide appropriate solubility within the hydrocarbon medium and revealed an excellent oxidation induction time of ∼11-12 min.

As an emerging nano-functional material, fluorescent carbon nanodots (CDs) have made breakthroughs in many fields. In our research, graphite-like nitrogen-doped carbon nanodots (N-CDs) with excellent down- and up-conversion fluorescent properties were synthesized by a facile one-step solvothermal method using tri-isopropanolamine (TIPA) as carbon and nitrogen sources. Mean particle diameter from 2.85 to 5.62 nm can be obtained by controlling the amount of HNO3 during synthesis. With low cytotoxicity and excellent fluorescence properties, the prepared N-CDs can well label HeLa cells, which has great potential in the field of cell imaging. This work could enrich the research on the preparation and application of N-CDs.

Refaee, Ayaat A. published the artcileNano-bio finishing of cotton fabric with quaternized chitosan Schiff base-TiO₂-ZnO nanocomposites for antimicrobial and UV protection applications, Safety of Triisopropanolamine, the publication is European Polymer Journal (2022), 111040, database is CAplus.

The purpose of this work is to offer a novel approach to designing multifunctional tech. cotton textiles by coating them with smart bio-materials. Two different ternary nanocomposites (NC1, NC2) comprising (ammonium-salicylidene) chitosan Schiff base (ASCSB), TiO₂, and ZnO nanoparticles were in-situ prepared and applied for treating cotton fibers using the facile pad-dry-cure process to impart antimicrobial and UV protection characteristics. Notably, NC1 is TiO₂-rich, while NC2 is rich in ZnO. The physicochem. and visual characteristics of the new nanocomposites and the treated fabrics were investigated by spectral, microscopic, and thermal methods. The as-prepared NC1 exhibited a more homogeneous distribution, higher depositing d. and smaller mean nanoparticle size (48 nm) when compared to NC2 (56 nm). In contrast, NC2-treated fabrics showed a higher depositing d. of nanoparticles than NC1-treated ones. The treated cotton fibers demonstrated strong and sustainable antimicrobial impacts on S. aureus, E. coli, and C. albicans pathogens, with more effective performance for NC2-treated textiles in comparison to NC1-treated fabrics. The NC2-remediated cotton fabrics demonstrated a higher UV protection factor (UPF) value (53) as compared to NC1-coated fabrics (35), indicating that the ZnO-rich nanocomposite endowed cotton fabrics with more UV protection than TiO₂-rich nanocomposite.

Guo, Jing published the artcileExtended suspect screening strategy to identify characteristic toxicants in the discharge of a chemical industrial park based on toxicity to Daphnia magna, Recommanded Product: Triisopropanolamine, the publication is Science of the Total Environment (2019), 650(Part_1), 10-17, database is CAplus and MEDLINE.

With an increasing amount of industrial wastewater being discharged and the numerous chems. existed in, methods to identify toxicants in such complex matrixes are urgently needed for source control and quality management. In vivo toxicity to Daphnia magna was evaluated in the effluent of a wastewater treatment plant (WWTP). An extended suspect screening strategy was performed by bioassay-directed fractionation, accompanied with suspect screening of 228 suspect chems. in toxic fractions based on their mass characteristics and chromatog. characteristics. A toxicity evaluation of the original samples, organic components extracted by solid-phase extraction (SPE) and the filtered samples showed that organic compounds extracted by SPE were the main toxic components. Four of the 26 fractions of the organic extracts exhibited a toxic unit (TU) >1.0, with hydrophobic organic compounds contributing most to the toxicity. Twenty-eight of the 228 suspects were identified in four toxic fractions, with 53.6% of the suspects elucidated by spectrum interpretation based on mass characteristics and 53.8% more false pos. suspects removed based on chromatog. characteristics. Finally, 6 pollutants, including imazalil, prometryn, propiconazole, tebuconazole, buprofezin and diazinon, were further confirmed and explained 48.79% of the observed toxicity. With 2.48 times more of the toxicity explained and 90% of the labor saved, the extended suspect screening strategy enabled more efficient and reliable identification compared to traditional quant. anal. and non-target screening, especially for identification of characteristic toxicants in complex environmental matrixes.

Noh, Chanho published the artcileHighly stable aqueous organometallic redox flow batteries using cobalt triisopropanolamine and iron triisopropanolamine complexes, Recommanded Product: Triisopropanolamine, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2021), 126966, database is CAplus.

Two metal-organic complexes consisting of new triisopropanolamine (TiPA) ligand and two transition cobalt (Co) and iron (Fe) metals (Co(TiPA) and Fe(TiPA)) are suggested and used as redox couple for redox flow battery (RFB) with potassium hydroxide (KOH) electrolyte. The redox reactivity of Co(TiPA) and Fe(TiPA) adopting TiPA ligand is measured and their reaction mechanism is compared with that of complexes containing triethanolamine (TEA) ligand (Co(TEA) and Fe(TEA)) that are conventionally considered. According to evaluations, the reaction rate of all complexes is controlled by their diffusion rate. In a comparison of the complexes, that of TEA complexes is faster than that of TiPA complexes. This means that the viscosity of TEA complexes is lower than that of TiPA complexes. However, regarding the stability in KOH, the stability of TiPA complexes is much better than that of TEA complexes, enabling the stable redox reactions over a long period. Considering the reduction potential of complexes and their stabilization constant, TiPA complexes have a higher stabilization constant than TEA complexes because the redox reaction of TiPA complexes is stably performed, whereas the Fe ions of Fe(TEA) are precipitated for charging process and the preciptation induces irreversible reaction in KOH. This is confirmed by the solidified Fe atoms observed onto carbon felt after RFB test. When the performance of RFB using Co(TiPA) and Fe(TiPA) is measured, its capacity retention is well maintained for 100 cycle (298 h), while this RFB shows superior energy efficiency (77% at 40 mA cm^-2) and power d. (81.3 mW cm^-2 at 160 mA cm^-2).

Noh, Chanho published the artcileOptimization of iron and cobalt based organometallic redox couples for long-term stable operation of aqueous organometallic redox flow batteries, Product Details of C9H21NO3, the publication is Journal of Power Sources (2021), 229799, database is CAplus.

The optimal electrolyte condition for iron (Fe) and cobalt (Co) coordinated with Triisopropanolamine (TiPA) and 3-[Bis(2-hydroxyethyl)amino]-2-hydroxypropanesulfonic acid (DIPSO) is suggested for aqueous organometallic redox flow batteries (AMORFBs), while best combination for improving its long-term stability is determined Co(TiPA) is optimal catholyte due to excellent redox reactivity and stability, while such benefits are proved by the comparison of formation constant which is proportional to the strength of coordination bonds within metal complex. That of Co(TiPA) is 10.8 times higher than that of Co(DIPSO) that is a competitor for catholyte. Regarding anolyte, Fe(DIPSO) formed by 1:1.5 mol ratio of Fe ion to DIPSO ligand is more stable than Fe(TiPA) that is a competitor for anolyte. The stability is exptl. verified by linear sweep voltamogram. According to the measurements, In Fe(DIPSO), potential required for the solidification of Fe ions, which causes the performance degradation of AMORFB, is placed more neg. than that required in Fe(TiPA). This indicates the when Fe(DIPSO) is used, the stable cut-off voltage range for AMORFB tests is extended with its performance improvement. Furthermore, since the solidified Fe further acts as catalyst for undesirable hydrogen evolution reaction, retarding the solidification of Fe ions enhances the performance and stability of AMORFB. In in-situ AMORFB cell tests performed to validify the electrochem. evaluations of metal complexes, the stability of AMORFB using Co(TiPA) and Fe(DIPSO) is best. Regarding its performance, charge capacity is high as 15.5 Ah L^-1, while its capacity loss rate is low as 0.018 Ah L^-1cyc^-1 for 100 cycles.

Zhang, Feng published the artcileEffect of new type low-temperature early strength accelerator on the strength and durability of concrete, Recommanded Product: Triisopropanolamine, the publication is Hunningtu (2021), 98-102, 111, database is CAplus.

A new type of low-temperature early-strength accelerator, without alkali, chlorine and sulfate ions, was prepared with calcium bromide, lithium bromide and triisopropanolamine, and its effects on the workability, strength and durability of concrete at 5°C were studied. The results show that, the low-temperature early strength accelerator had little influence on the workability of concrete, but it hada significant low-temperature early-strength performance and a good adaptability to different fly ash contents (such as 10%, 20%, 30%). The 1 d, 3 d and 7 d compressive strength ratios of the C50 concrete mixed with early strength accelerators cured at 5°C, reached 157%, 132% and 123% resp., and the retention rates from 28 d to 120 d all exceeded 110%. The strength of concrete at each age was already close to that of the contrast sample cured at 20°C. The incorporation of low-temperature early strength accelerators would increase the dry shrinkage of concrete slightly, and the elec. flux of concrete before 56 d would increase by 6% to 14%. However, the elec. flux of concrete after 90 d could be reduced and the frost resistance of concrete could be improved. The method of compounding 2% expansion agent and 3% silica fume in the early strength accelerator could reduce the dry shrinkage of concrete by 23% compared with that of the contrast sample at 120 d, and the elec. flux at 56 d was less than 1000 C. By the way, this method did not lose the strength of concrete.

Zhang, Feng published the artcileEffect of triisopropanolamine on compressive strength and early hydration of cement at low temperature, Related Products of alcohols-buliding-blocks, the publication is Journal of Wuhan University of Technology, Materials Science Edition (2020), 35(3), 611-619, database is CAplus.

Triisopropanolamine (TIPA) was used as an early strength component to study its effects on mortar strength, cement paste setting time and early hydration characteristic of cement. And the early strength mechanism of TIPA at low temperature of 5°C was also discussed. The results showed that, at 5°C, the incorporation of TIPA promoted the condensation of cement paste, shortened the initial and final setting time, and accelerated the strength development of specimens at all ages, among which the strength after 3 d increased significantly. The 1, 3, 7, and 28 d compressive strength ratios of the mortars mixed with 1% TIPA could reach 196%, 179%, 160% and 110% resp., and the mortar strength after 3 d exceeded that of the contrast sample cured at 20°C. Under low temperature condition, TIPA could promote the hydration reaction of cement, shorten the induction period and advance the acceleration period. Furthermore, the maximum heat release rate and cumulative heat release quantity would be all increased, and the cumulative heat release of the cement mixed with TIPA hydrated for 12 h and 7 d increased 73% and 38% resp. TIPA could shorten the nucleation and crystal growth (NG) stage and increase its hydration degree significantly, so it promoted cement hydration reaction. Addnl., the hydration reaction rates in phase boundary reaction (I) phase and diffusion reaction (D) phase were increased, and the duration of I process was prolonged, thereby the development of specimen strength would be accelerated. TIPA did not obviously change the types of hydration products, but increased the content of Ca(OH)2 in the samples and the degree of cement hydration. After hydration to 7 d, large amounts of hydration products, whose surface was smooth, were formed and bonded into sheets, and the structural d. of samples improved significantly.
