Dashti, Amir published the artcileQuantitative structure property relationship schemes for estimation of autoignition temperatures of organic compounds, Synthetic Route of 122-20-3, the publication is Journal of Molecular Liquids (2020), 111797, database is CAplus.

We have extended a quant. structure-property relationship (QSPR) scheme to estimate the auto-ignition temperatures (AIT) of organic compounds by employing GA-ANFIS, PSO-ANFIS, DE-ANFIS and GP methods. The average absolute relative deviations (%AARD) are 7.96, 6.29, 8.85 and 8.26, resp. The range of these values appears to match that of exptl. error in AIT measurements, suggesting strong models. For organic compounds, the AIT can be estimated using the above-mentioned methods, from mol. structure. This goal is possible using only 9 theor. descriptors.

Walker, Brandon published the artcileMolecular dynamics free energy simulations of ATP:Mg²⁺ and ADP:Mg²⁺ using the polarisable force field AMOEBA, Formula: C9H21NO3, the publication is Molecular Simulation (2021), 47(5), 439-448, database is CAplus and MEDLINE.

ATPases and GTPases are two important classes of protein that play critical roles in energy transduction, cellular signalling, gene regulation and catalysis. These proteins use cofactors such as nucleoside di and tri-phosphates (NTP, NDP) and can detect the difference between NDP and NTP which then induce different protein conformations. Mechanisms that drive proteins into the NTP or NDP conformation may depend on factors such as ligand structure and how Mg²⁺ coordinates with the ligand, amino acids in the pocket and water mols. Here, we have used the advanced electrostatic and polarisable force field AMOEBA and mol. dynamics free energy simulations (MDFE) to examine the various binding mechanisms of ATP:Mg²⁺ and ADP:Mg²⁺. We compared the ATP:Mg²⁺ binding with previous studies using non-polarisable force fields and exptl. data on the binding affinity. It was found that the total free energy of binding for ATP:Mg²⁺ (-7.00 2.13 kcal/mol) is in good agreement with exptl. values (-8.6 .2 kcal/mol) [1]. In addition, parameters for relevant protonation states of ATP, ADP, GTP and GDP have been derived. These parameters will allow for researchers to investigate biochem. phenomena involving NTP’s and NDP’s with greater accuracy than previous studies involving non-polarisable force fields.

Joshi, Suraj R. published the artcileConstruction, analysis and validation of co-expression network to understand stress adaptation in Deinococcus radiodurans R1, Related Products of alcohols-buliding-blocks, the publication is PLoS One (2020), 15(6), e0234721, database is CAplus and MEDLINE.

In the current study, we have performed system-level anal. for Deinococcus radiodurans R1 by constructing a gene co-expression network based on several microarray datasets available in the public domain. This condition-independent network was constructed by Weighted Gene Co-expression Network Anal. (WGCNA) with 61 microarray samples from 9 different exptl. conditions. We identified 13 co-expressed modules, of which, 11 showed functional enrichments of one or more pathway/s or biol. process. Comparative anal. of differentially expressed genes and proteins from radiation and desiccation stress studies with our co-expressed modules revealed the association of cyan with radiation response. We obtained 7 TFs for radiation and desiccation responsive modules. The expressions of 3 TFs were validated in response to gamma radiation using qRT-PCR. Along with the TFs, selected close neighbor genes of two important TFs, viz., DR_0997 (CRP) and DR_2287 (AsnC family transcriptional regulator) in the darkgreen module were also validated. In our network, among 13 hub genes associated with 13 modules, the functionality of 5 hub genes which are annotated as hypothetical proteins (hypothetical hub genes) in D. radiodurans genome has been revealed. Overall the study provided a better insight of pathways and regulators associated with relevant DNA damaging stress response in D. radiodurans.

Liao, Xia-ling published the artcileMicrostructural characterization of cement in the presence of alkanolamines, Product Details of C9H21NO3, the publication is Materials Today Communications (2021), 102386, database is CAplus.

In order to understand the potential issues regarding the cement performance over time in the presence of alkanolamines, such as triethanolamine (TEA) and triisopropanolamine (TIPA), this investigation provided a series of quant. phase characterization to monitor the hydration and microstructure of cement pastes. The addition of 0.02% alkanolamines to cement promoted the strength development and altered the hydration kinetics at early ages. The aluminate reaction was greatly promoted, which resulted in the formation of hydrosulfoaluminates with a high monosulfoaluminate-to-ettringite ratio due to the facilitated dissolution of the intermediate phase. The morphol. and chem. composition of the hydrates, as well as the porosity of the pastes, were also influenced by the altered hydration kinetics. Particularly, TIPA markedly reduced Si/Ca ratio (from 0.61 to 0.51) and increased Fe/Ca ratio (from 0.016 to 0.036) in the C-S-H gel at the early stage of hydration. Based on the variations in microstructural features subjected to the alkanolamines, the durability and long-term performance of the cement, including the phase variation, resistance to sulfate or chloride ingression and volume stability, were discussed.

Cheng, Rui published the artcileA nucleotide-sensing endonuclease from the Gabija bacterial defense system, Name: Triisopropanolamine, the publication is Nucleic Acids Research (2021), 49(9), 5216-5229, database is CAplus and MEDLINE.

The arms race between bacteria and phages has led to the development of exquisite bacterial defense systems including a number of uncharacterized systems distinct from the well-known restriction-modification and CRISPR/Cas systems. Here, we report functional analyses of the GajA protein from the newly predicted Gabija system. The GajA protein is revealed as a sequence-specific DNA nicking endonuclease unique in that its activity is strictly regulated by nucleotide concentration NTP and dNTP at physiol. concentrations can fully inhibit the robust DNA cleavage activity of GajA. Interestingly, the nucleotide inhibition is mediated by an ATPase-like domain, which usually hydrolyzes ATP to stimulate the DNA cleavage when associated with other nucleases. These features suggest a mechanism of the Gabija defense in which an endonuclease activity is suppressed under normal conditions, while it is activated by the depletion of NTP and dNTP upon the replication and transcription of invading phages. This work highlights a concise strategy to utilize a DNA nicking endonuclease for phage resistance via nucleotide regulation.

Cui, Lei published the artcileExperimental study on multi-component corrosion inhibitor for steel bar in chloride environment, SDS of cas: 122-20-3, the publication is Construction and Building Materials (2021), 125533, database is CAplus.

This paper investigates one type of multi-component corrosion inhibitor for steel bars in chloride environment. Triethanolamine (TEA), tri-isopropanolamine (TIPA), sodium monofluorophos-phate (MFP) and sodium molybdate (T-4) were proportioned to prepare this multi-component corrosion inhibitor. Corrosion behavior of steel bar was evaluated using the polarization curve, electrochem. impedance spectroscopy (EIS) and SEM (SEM). The polarization curves were fitted using the adsorption isotherm models. Exptl. results indicated that the steel bar corrosion in chloride solution can be reduced by the addition of either organic or inorganic corrosion inhibitors. This is attributed to the fact that organic corrosion inhibitor can form an adsorption film on the steel bar surface and inorganic corrosion inhibitor abates electrochem. reaction of steel bars. Compared to single component corrosion inhibitors, the corrosion rate of steel bars in simulated pore solution was significantly restrained by the multi-component corrosion inhibitor. The adsorption of multi-component corrosion inhibitor on the surface of steel bar can significantly reinforce the passive film by means of phys. (organic) or chem. (inorganic) process. For all the investigated corrosion inhibitors, the adsorption isotherms were in good agreement with exptl. results. The EIS result and equivalent electrochem. circuit confirmed the chem. reaction and phys. adsorption process of the multi-component corrosion inhibitor. Therefore, the chloride induced corrosion of steel bars can be effectively controlled by the multi-component corrosion inhibitor.

Jiang, Minghui published the artcileInhibition effect of different corrosion inhibitors on steel bars corrosion and improvement effect after double doped, Application In Synthesis of 122-20-3, the publication is Science Journal of Chemistry (2021), 9(4), 105-112, database is CAplus.

Reinforced concrete structures are easily corroded in the Salt Lake areas of China, especially in harsh environmental circumstance, such as freezing-thawing cycles, wetting-dry, et al, thus causing a lot of damage problems (concrete deterioration and steel bars corrosion). This research investigation was a research study which was to solve the corrosion problem of reinforced concrete structures under the chloride environmental circumstance through the electrochem. performance and mech. properties test of the reinforced mortar specimens, the effect of single or compound doping of two organic and two inorganic corrosion inhibitors to the electrode potential, electrochem. impedance spectroscopy and mech. properties of the reinforced mortar were investigated. The exptl. conclusion demonstrated that the organic or inorganic corrosion inhibitors after single and compound doping showed some degree influence on the electrode potential and mech. properties of the reinforced mortar specimens. Meanwhile, when the ratio of triethanolamine (TEA):triisopropanolamine (TIPA) was 7:3, sodium monofluorophosphate (MFP):sodium molybdate was 5:5, the compressive strength and flexural strength of mortar after curing for 28 days were greater than 90, it indicated that these proportions showed the best corrosion resistance performance of steel bars. Therefore, these proportions of corrosion inhibitors could be used in reinforced concrete structures. The significant was that these results could provide theor. guidance and tech. basis for the study of corrosion damage of reinforced concrete structures in the future.

Deng, Xiufeng published the artcileEffect of organic alkali on hydration of GGBS-FA blended cementitious material activated by sodium carbonate, Category: alcohols-buliding-blocks, the publication is Ceramics International (2022), 48(2), 1611-1621, database is CAplus.

Sodium carbonate (SC) activated ground granulated blast-furnace slag (GGBS) and fly ash (FA) is a potential substitute of traditional cement with ultra-low carbon footprint. However, its hydration rate and strength growth are limited, owing to the slow leaching of ions during the activation of weak base. In this work, 60% wet-grinded GGBS and 40% FA were blended as the binder, and two organic alkalis, i.e. triethanolamine (TEA) and triisopropanolamine (TIPA), were adopted to facilitate the ions dissolution and pozzolanic reaction of SC activated GGBS-FA blended cementitious material (SCSF). The compressive strength was tested and the hydration kinetics was studied by hydration heat and chem. shrinkage. Besides, ions leaching behavior was characterized by ICP; hydrates and microstructure were also detected by XRD, TG-DTG and SEM. Results indicated that the addition of TEA or TIPA significantly promoted the ions dissolution 0.05% TEA increased the concentration of leached Ca2+, Al3+ and Fe3+ by 36%, 33% and 1545%, resp. This solubilizing effect was also found in TIPA. Moreover, these two chems. could promote the formation of hydrates, such as C-S(A)-H gel, hydrotalcite, calcite and aragonite, especially at the early period; these also activated the hydration process of SCSF effectively, and the compressive strength of the mortar reached above 40.0 MPa at 7 d and 48.0 MPa at 28 d. The carbon emission of the designed system is 85.9% and 55.9% lower than that of PC and strong base activated GGBS system, resp.

Present work analyzes the overall carbon dioxide chem. absorption process using tertiary amines in aqueous solution, taking into account absorption rate exptl. data and ¹³C and ¹H NMR. These studies try to detect the causes because different behaviors are obtained for absorption curves at different carbon dioxide loadings. The combined use of these techniques allows to evaluate the weight of different variables (chem. kinetics, mechanism, hydrodynamics, etc) upon the absorption overall process.

A new Methyl red (MR) based silatrane was synthesized in high yield by the transesterification reaction of Methyl red-amidopropyltrimethoxysilane 1 (MR-APTMS) and trisisopropanolamine. Single crystal x-ray diffraction anal. was used to deduce the structure of silatrane 2 which was also supported by NMR (¹H, ¹³C) spectroscopy, mass spectrometry, FTIR, UV-visible and DFT studies. Silatrane 2 when surveyed for cation recognition ability with a library of metal ions in CH₃CN/H₂O (9 : 1, volume/volume) was found to act as an excellent UV-visible probe for the selective recognition of Hg²⁺in vitro. Also, quantum mech. calculations of the interaction complex [MR-APS-Hg]²⁺3 using DFT at the B3LYP level in conjunction with the LanL2DZ basis set determined the geometric and the stability parameters of the surveyed interaction.
