Dichloroacetic acid (DCA) exhibits great potential as an herbicide (nontoxic, easily biodegradable), but its application in agriculture has scarcely been investigated. Since DCA readily undergoes photolysis when exposed to natural light or UV irradiation, there is a large activity loss in controlling weeds. To improve the activity of DCA, we proposed the transformation of DCA into an ionic salt form by using an herbicidal ionic liquids (HILs) strategy. Herein, fifteen novel ammonium dichloroacetates were designed and achieved for the first time. When compared to the anionic precursor DCA, three salts with longer alkyl chains ranging from dodecyl to hexadecyl chains were found to enhance not only the post emergence herbicidal activity but also the rates of activity against some broadleaf weeds under greenhouse conditions. The enhancement was due to the synergistic effect of structural factors, such as the surface activity, solubility and stability arising from their ionic nature. In addition, IL 13 possesses a low phytotoxicity to cotton plants with a favorable selectivity index above 2. This study will be useful for the design of new, high-performance herbicidal formulations.

Zhang, Ting published the artcileEffect of TIPA on mechanical properties and hydration properties of cement-lithium slag system, Recommanded Product: Triisopropanolamine, the publication is Journal of Environmental Management (2020), 111274, database is CAplus and MEDLINE.

Effect of triisopropanolamine (TIPA) on compressive strength and hydration properties of cement-lithium slag (LS, 30%) paste was studied. The results demonstrated that the addition of TIPA is advantageous for compressive strength at 7 d, 28 d and 60 d. The reason was related to the pore complexity and hydration process of cement and LS. TIPA reduced the total porosity, and increased the fractal dimension, making the pore structure more complicated. In addition, TIPA promoted the pozzolanic reaction of LS and the hydration of cement, expediting the formation of C-S(A)-H gel. TIPA accelerated the dissolution of aluminate ions, silicate ions and ferric ions in the pore solution, thereby accelerating the pozzolanic reaction of LS. During the hydration of cement-LS paste, TIPA facilitated the conversion of ettringite to the AFm-like phase and produced more C-A-S-H gel by promoting the dissolution of aluminate ions.

Wang, Jie published the artcileHydration and mechanical properties of cement-marble powder system incorporating triisopropanolamine, Related Products of alcohols-buliding-blocks, the publication is Construction and Building Materials (2021), 266(Part_B), 121068, database is CAplus.

This study aimed to improve the mech. properties of cement-marble powder (MP) mortar by incorporating triisopropanolamine (TIPA) to promote the optimal utilization of marble waste. In this research, the workability, compressive strength, capillary water absorption, hydration process and microstructure of cement-MP system were investigated. From the exptl. results, it was found that the incorporation of TIPA enhanced the mech. strength of cement-MP mortar. Moreover, the capillary water absorption of cement-MP mortar was improved when the TIPA dosage exceeded 0.06%. The enhancement of these properties was mainly due to the acceleration effect of TIPA on the cement-MP system hydration process, despite the fact that its air entraining effect would have a neg. effect. Incorporating TIPA in cement-MP system accelerated the dissolution of Fe3+ ions in ferrite phase to promote the hydration of cement, which certainly facilitated the consumption of SO2-4 ions, thus promoting the formation of calcium aluminocarbonate. Addnl., no obvious difference was observed in the workability and setting characteristics between cement-MP system with and without TIPA.

Liu, Xiaohai published the artcileImprovement in chloride immobilization of cement-metakaolin system by triisopropanolamine, Product Details of C9H21NO3, the publication is Applied Clay Science (2020), 105656, database is CAplus.

Metakaolin (MK) is a widely used admixture in chloride immobilization which is conducive to the durability of reinforced concrete. In this study, triisopropanolamine (TIPA) was added into cement-MK system to improve the chloride immobilization by expediting the pozzolanic reaction of MK. The effect of TIPA on hydration of binder composed of 90% Portland cement and 10% MK was investigated, and the hydration behavior was characterized by thermogravimetric anal., X-ray diffraction, NMR spectroscopy, and mercury intrusion porosimetry, based on the evaluation of pozzolanic reaction of MK by ion dissolution Results indicated that TIPA promoted the hydration of both MK and cement, and chloride immobilization was also improved. The mechanism for the improvement was involved in three aspects: a) TIPA facilitated the dissolution of aluminum from MK to obtain more chloroaluminate salts, strengthening chem. binding; b) TIPA accelerated hydration of cement and MK for more C-S-H gel, conducive to the phys. adsorption; c) TIPA increased the amount of hydrates to refine the pore structure, hindering the migration of chloride ion. This investigation provided one new method for improving the pozzolanic reaction of MK to enhance chloride immobilization of cement-MK system.

Li, Chunbao published the artcileEffect of triisopropanolamine on chloride binding of cement paste with ground-granulated blast furnace slag, Category: alcohols-buliding-blocks, the publication is Construction and Building Materials (2020), 119494, database is CAplus.

Chloride was one of important factors resulting in steel bar corrosion in reinforced concrete when using sea resources. In this paper, an attempt to promote the chloride binding capacity of the cement-ground-granulated blast furnace slag (GGBS) system was made by adding triisopropanolamine (TIPA). The paste was prepared by 70 wt% cement and 30 wt% GGBS, sodium chloride, TIPA (0.03%, 0.06% and 0.10%, by weight of binder) and water. The paste was cured for 7 d and 60 d, and the chloride binding ratio (CBR) were measured. The hydration heat and compressive strength were examined, then the hydrates and pore structure of the hardened paste were also analyzed; and the effect of TIPA on aluminum and ferric dissolution of GGBS was also studied. The results showed that TIPA could promote CBR at both 7 d and 60 d. The reason was ascribed to three aspects: (1) TIPA facilitate the formation of FS, which contribute to chem. binding; (2) TIPA promoted the formation of C-S(A)-H gel, which would increase the phys. binding; (3) TIPA refined the pore structure and increased fractal dimension, which could enhance the migration resistance. Furthermore, TIPA promoted cement hydration and pozzolanic reaction of GGBS by facilitated the dissolution of aluminum and ferric in GGBS. Addnl., the formation of Friedel’s salt was promoted due to the transformation of ettringite to AFm-like phase promoted by TIPA. Such results suggested a new way to improve chloride binding capacity of cementitious materials by adding alkanolamine.

Shareef, Afzaal M. published the artcileComparison of RNA synthesis initiation properties of non-segmented negative strand RNA virus polymerases, SDS of cas: 122-20-3, the publication is PLoS Pathogens (2021), 17(12), e1010151, database is CAplus and MEDLINE.

It is generally thought that the promoters of non-segmented, neg. strand RNA viruses (nsNSVs) direct the polymerase to initiate RNA synthesis exclusively opposite the 3′ terminal nucleotide of the genome RNA by a de novo (primer independent) initiation mechanism. However, recent studies have revealed that there is diversity between different nsNSVs with pneumovirus promoters directing the polymerase to initiate at positions 1 and 3 of the genome, and ebolavirus polymerases being able to initiate at position 2 on the template. Studies with other RNA viruses have shown that polymerases that engage in de novo initiation opposite position 1 typically have structural features to stabilize the initiation complex and ensure efficient and accurate initiation. This raised the question of whether different nsNSV polymerases have evolved fundamentally different structural properties to facilitate initiation at different sites on their promoters. Here we examined the functional properties of polymerases of respiratory syncytial virus (RSV), a pneumovirus, human parainfluenza virus type 3 (PIV-3), a paramyxovirus, and Marburg virus (MARV), a filovirus, both on their cognate promoters and on promoters of other viruses. We found that in contrast to the RSV polymerase, which initiated at positions 1 and 3 of its promoter, the PIV-3 and MARV polymerases initiated exclusively at position 1 on their cognate promoters. However, all three polymerases could recognize and initiate from heterologous promoters, with the promoter sequence playing a key role in determining initiation site selection. In addition to examining de novo initiation, we also compared the ability of the RSV and PIV-3 polymerases to engage in back-priming, an activity in which the promoter template is folded into a secondary structure and nucleotides are added to the template 3′ end. This anal. showed that whereas the RSV polymerase was promiscuous in back-priming activity, the PIV-3 polymerase generated barely detectable levels of back-primed product, irresp. of promoter template sequence. Overall, this study shows that the polymerases from these three nsNSV families are fundamentally similar in their initiation properties, but have differences in their abilities to engage in back-priming.

Li, Xin published the artcileSmall molecule-mediated upregulation of CCR7 ameliorates murine experimental autoimmune encephalomyelitis by accelerating T-cell homing, Formula: C9H21NO3, the publication is International Immunopharmacology (2017), 33-41, database is CAplus and MEDLINE.

Impairing the infiltration of immune cells into the CNS is a promising target for suppressing the development of multiple sclerosis (MS) and its animal model exptl. autoimmune encephalomyelitis (EAE). Here, we found that oral administration of a synthetic small mol. compound Fc24 showed potential preventive effects on the development of EAE, including the reduction in EAE severity and a delay in the onset of the disease. Fc24 facilitated the accumulation of both CD4⁺ and CD8⁺ T cells within spleen and lymph nodes, while having no effect on MOG-specific T cell responses. Furthermore, CCR7 expression was upregulated by Fc24 on activated T cells in vivo and in vitro, accompanied by ERK activation in the treated T cells in response to CCL19. These findings demonstrate that small mol.-mediated CCR7 upregulation might ameliorate EAE by facilitating T cell homing into and within lymphoid organs, and that Fc24 may be a potential candidate for modifying the development of EAE.

Wang, Zhan-Feng published the artcileAn intermediate state of T7 RNA polymerase provides another pathway of nucleotide selection, SDS of cas: 122-20-3, the publication is Chinese Physics B (2017), 26(10), 100203/1-100203/16, database is CAplus.

Phage T7 RNA polymerase is a single-subunit transcription enzyme, transcribing template DNA to RNA. Nucleoside triphosphate (NTP) selection and translocation are two critical steps of the transcription elongation. Here, using all-atom mol. dynamics simulations, we found that between pre- and post-translocation states of T7 RNA polymerase an intermediate state exists, where the O helix C-terminal residue tyrosine 639, which plays important roles in translocation, locates between its pre- and post-translocation positions and the side chain of the next template DNA nucleotide has moved into the active site. NTP selection in this intermediate state was studied, revealing that the selection in the intermediate state can be achieved relying on the effect of Watson-Crick interaction between NTP and template DNA nucleotide, effect of stability of the components near the active site such as the nascent DNA-RNA hybrid and role of tyrosine 639. This indicates that another NTP-selection pathway can also exist besides the main pathway where NTP selection begins at the post-translocation state upon the entry of NTP.

Liu, Chen published the artcileHeat-cured concrete: Improving the early strength and pore structure by activating aluminosilicate internal curing agent with triisopropanolamine, Recommanded Product: Triisopropanolamine, the publication is Journal of the American Ceramic Society (2019), 102(10), 6227-6238, database is CAplus.

Although heat-cured concrete (HCC) has received extensive research interests in recent years, it still suffers from problems including coarsened microstructure and low cement hydration degrees, which limited its application. Some of these problems can be solved by internal curing method resulting in low early strength of HCC and low-production efficiency. This study addressed this issue by activating the aluminosilicate internal curing agent (lightweight fine aggregate, LWFA) with triisopropanolamine (TIPA). More Al³⁺ and Fe³⁺ ions were dissolved from LWFA by TIPA, which assisted the formation of hydrates with cement ions in interfacial transition zone (ITZ), and enhanced the d. of ITZ in the early stage. The introduction of TIPA increased the early compressive strength of HCC, by ∼15.3%, 25.9%, and 28.0%, resp. for the cement cured for 1, 3, and 7 days compared with control samples. Moreover, the results of rapid chloride migration and water absorption depth also suggested that coupling the aluminosilicate internal curing agent with TIPA improved the pore structure of HCC.

Wu, Zhihong published the artcileEffect of aluminum sulfate alkali-free liquid accelerator with compound alkanol lamine on the hydration processes of Portland cement, Recommanded Product: Triisopropanolamine, the publication is Construction and Building Materials (2021), 125101, database is CAplus.

Aluminum sulfate alkali-free liquid accelerator is a kind of shotcrete admixture used in the construction of tunnels and culverts. In order to investigate the influence of alkanol amine in aluminum sulfate alkali-free liquid accelerator on cement hydration and strength, the different proportion of triethanolamine (TEA) and triisopropanolamine (TIPA) mixtures were added to aluminum sulfate alkali-free liquid accelerator. The mortar strength was measured by universal testing machine, and the hydration products were analyzed by XRD SEM and thermogravimetric anal. The results show that TEA can promote the hydration of C3A to form ettringite (AFt) and improve the early strength of cement, and TIPA can promote the hydration of ferrite phase, improve the degree of hydration, and promote the later strength of cement. The synergistic effect of TEA and TIPA in proper proportion can improve both the early strength and late strength of cement at all ages.
