Srivastava, Ashutosh published the artcileDeep eutectic solvents based on imidazolium cation and probing redox speciation of uranium oxides by electrochemical and theoretical simulation, Recommanded Product: 2,2′-Oxydiacetic acid, the main research area is imidazolium deep eutectic solvent electrochem thermogravimetric mol dynamics.

Two new deep eutectic solvents, different from hitherto known and based on common choline chloride, were prepared 1-methyl-3-decylimidazolium bromide mixed with hydrogen bond donors, malonic acid and diglycolic acid to form DES. Dissolution of uranium oxides (UO3 and UO2) was explored in both of them and characterization of the resultant solutions was carried out by IR, TGA and UV-Vis spectroscopy. Redox speciation of dissolved uranium oxides was probed in these redox-active DES through cyclic voltammetry, differential pulse voltammetry and in situ spectroelectrochem. measurements. Interestingly, the formation of uranium oxo species was observed through the dissolution of UO3 in both the DES. The electrochem. characteristics via redox thermodn. (peak potential and formal redox potential), transport property (diffusion coeffecient D0), heterogeneous electron transfer kinetic parameters (αn and k0) and mechanistic electron transfer of the dissolved uranium species in two DES were investigated. The speciation of uranium was decoded through the electronic absorption spectra of uranium in its lower oxidation states [U(V) and U(IV)] acquired through in situ spectroelectrochem. electrolysis with varying cathodic potentials. Studies were also carried out using mol. dynamics (MD) and d. functional theory (DFT) simulations to authenticate the electrochem. outcomes and to acquire the binding energy, optimized structure and MO diagram of dissolved uranium species. Further, the MD simulation sheds light on the probable equatorial coordinating atoms of dissolved uranium species. This is the first report, to the best of our knowledge, on imidazolium-based DES and actinide ions.

Dybczynski, Rajmund S. published the artcileSeparation of Rare Earth Elements (REE) by Ion Interaction Chromatography (IIC) Using Diglycolic Acid (ODA) as a Complexing Agent, Quality Control of 110-99-6, the main research area is separation rare earth element ion interaction chromatog; diglycolic acid complexing agent.

Abstract: The possibility of rare earth elements (REE) separation by ion interaction chromatog. (IIC) employing their complexes with diglycolic acid (ODA) in anion exchange mode has been studied theor. and exptl. Calculations, assuming that only trivalent complex is significantly uptaken by the stationary phase, indicated that at at pH 4-6, the retention in the lanthanide series should increase from La to the Tb-Dy-Ho region with yttrium showing apparent at. number (ApparatusAt.Number) of 671/2 and then decrease with further increase of at. number Chromatog. experiments in the system: Column: Eternity C18-mobile phase 5 mM ODA/8.6 mM TBAOH/0.6 mM HNO3; pH 4.60 confirmed theor. predictions. It was found that scandium at pH ≥ 4.0 elutes in front of the whole REE group but at low pH enters the region of light lanthanides. The non-monotonical change of affinity of the REE with the increase of at. number results in quite unusual order of elution of REE namely: Sc < La < Ce < Lu < Pr < Yb < Nd < Tm < Sm < Eu < Er≈Y < Gd < Ho < Tb≈Dy.

Jacobs, Jeffrey W. published the artcileDiscovery of Tenapanor: A First-in-Class Minimally Systemic Inhibitor of Intestinal Na+/H+ Exchanger Isoform 3, Computed Properties of 110-99-6, the main research area is tenapanor inhibitor intestine sodium hydrogen exchanger isoform 3 NHE3.

We present herein the design, synthesis, and optimization of gut-restricted inhibitors of Na+/H+ exchanger isoform 3 (NHE3). NHE3 is predominantly expressed in the kidney and gastrointestinal tract where it acts as the major absorptive sodium transporter. We desired minimally systemic agents that would block sodium absorption in the gastrointestinal tract but avoid exposure in the kidney. Starting with a relatively low-potency highly bioavailable hit compound (1), potent and minimally absorbed NHE3 inhibitors were designed, culminating with the discovery of tenapanor (28). Tenapanor has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of irritable bowel syndrome with constipation in adults.

Li, Xiaokang published the artcileIdentifying the Phytotoxicity and Defense Mechanisms Associated with Graphene-Based Nanomaterials by Integrating Multiomics and Regular Analysis, Formula: C4H6O5, the main research area is phytotoxicity graphene nanomaterial metabolomic proteomic; defense; graphene; metabolomics; nanotoxicity; photosynthesis; proteomics.

The application of graphene-based nanomaterials (GBNs) has attracted global attention in various fields, and understanding defense mechanisms against the phytotoxicity of GBNs is crucial for assessing their environmental risks and safe-by-design. However, the related information is lacking, especially for edible vegetable crops. In the present study, GBNs (0.25, 2.5, and 25 mg/kg plant fresh weight) were injected into the stems of pepper plants. The results showed that the plant defense was regulated by reducing the calcium content by 21.7-48.3%, intercellular CO2 concentration by 12.0-35.2%, transpiration rate by 8.7-40.2%, and stomatal conductance by 16.9-50.5%. The defense pathways of plants in response to stress were further verified by the downregulation of endocytosis and transmembrane transport proteins, leading to a decrease in the nanomaterial uptake. The phytohormone gibberellin and abscisic acid receptor PYL8 were upregulated, indicating the activation of defense systems. However, reduced graphene oxide and graphene oxide quantum dots trigger stronger oxidative stress (e.g., H2O2 and malondialdehyde) than graphene oxide in fruits due to the breakdown of antioxidant defense systems (e.g., cytochrome P 450 86A22 and P 450 77A1). Both nontargeted proteomics and metabolomics consistently demonstrated that the downregulation of carbohydrate and upregulation of amino acid metabolism were the main mechanisms underlying the phytotoxicity and defense mechanisms, resp.

Vasanthi, T. published the artcileExperimental observation of induced thermochromic effect and nematic defects in hydrogen bonded liquid crystals, Application of 2,2′-Oxydiacetic acid, the main research area is hydrogen bond crystal temperature band gap energy.

Hydrogen bonded liquid crystal mixtures are derived from: (i) non-mesogenic compounds of diglycolic acid (DGA), (ii) mesogenic compounds of 4-amyloxybenzoic acid (5OBA) and (iii) 4-hexyloxy benzoic acid (6OBA). The existence of intermol. H-bond is confirmed with FTIR and validated using the d. functional theory studies. Polarized light microscopy and differential scanning calorimetry are used to observe the phase variations and transition temperature In addition, enthalpy values of different mesogenic phases are determined It is worth mentioning that the nematic mesogenic defects with S = ±1 and S = +1/2 are also analyzed. In order to discuss the induced higher order smectic F phase and its stability, the d. functional theory study is applied. The band gap energy of the hydrogen bonded liquid crystal mixtures is found to be 5.1780 eV, based on the HUMO-LUMO approach. This induced thermochromic effect of hydrogen bonded liquid crystal mixtures is a useful phenomenon that can be utilized in optical device applications. In this paper, variation on liquid crystal parameters as well as the formation of H-bond between an acceptor and a donor, along with the extension of a chain length, are also reported.

Shen, Zhongjing published the artcileFabrication of hollow cube dual-semiconductor Ln2O3/MnO/C nanocomposites with excellent microwave absorption performance, SDS of cas: 110-99-6, the main research area is lanthanide oxide carbon manganese semiconductor nanocomposite microwave absorption; 3d-4f metal−organic frameworks; band gap; dual-semiconductor; hollow structure; microwave absorption.

Metal-organic frameworks (MOFs) have been verified as ideal precursors for preparing highly effective microwave absorbers. However, it is still challenging to fabricate a thin, lightweight, and well-organized nanostructure with strong microwave absorption (MA) capability and wide absorption bandwidth. In this study, hollow cube dual-semiconductor Ln2O3/MnO/C (Ln = Nd, Gd, Er) nanocomposites, which are effective microwave absorbers, have been fabricated via one-step high-temperature carbonization of Ln-Mn-MOFs. The effect of band gap on the MA performance of various nanocomposites synthesized at the same carbonization temperature is investigated. Gd2O3/MnO/C-800 shows superior MA capacity with maximum reflection loss (RLmax) of -64.4 dB at 12.8 GHz and 1.86 mm-thickness. When the thickness is 1.44 mm, the RL value is obtained as -52.7 dB at 16.8 GHz, and at a low frequency of 4.36 GHz and thickness of 4.59 mm, the RL value reaches -56.4 dB. Further, the effect of temperature on the MA properties of Gd2O3/MnO/C is examined The results reveal that Gd2O3/MnO/C-700 has an ultrahigh MA bandwidth of 6.6 GHz, covering the entire Ku bands at 2.09 mm-thickness. Overall, this work demonstrates a facile strategy to construct hollow, homogeneous ternary composites with outstanding MA performance.

Kolacinska, Kamila published the artcileApplication of new covalently-bound diglycolamide sorbent in sequential injection analysis flow system for sample pretreatment in ICP-MS determination of 239Pu at ppt level, Synthetic Route of 110-99-6, the main research area is diglycolamide sorbent sequential injection analysis pretreatment plutonium ICP MS; Diglycolamide; ICP-MS; Nuclear reactor coolant; Plutonium; Sequential injection analysis; Solid-phase extraction.

Diglycolamide ligands are widely applied in the anal. of radionuclides, especially lanthanides and actinides. They are used in liquid-liquid extraction procedures or in solid-phase extraction sorbents where they are adsorbed on the surface of hydrophobic polymers. The main objective of this study was to synthesize the N,N,N’N’-tetrahexyl diglycolamide with one vinyl terminating group (vTHDGA) for further covalent immobilization on the polystyrene-divinylbenzene polymeric support. The obtained complexing resin (THDGA) was employed for the mechanized sample pretreatment in the Sequential Injection Anal. – Lab-on-Valve (SIA-LOV) flow system for the determination of 239Pu using ICP-MS detection. The anal. procedure was optimized in terms of selectivity towards several other radionuclides and elements forming potentially isobaric interferences in mass spectrometry. For 100 mL volume of sample to be analyzed, the method detection limit (MDL) was 96 mBq L-1 (42 pg L-1). The developed method was employed for the determination of 239Pu in real samples of a nuclear reactor coolant and spent fuel pool water from a nuclear reactor.

Reed, Kristi J. published the artcileDiethylene glycol and its metabolites induce cell death in SH-SY5Y neuronal cells in vitro, Application of 2,2′-Oxydiacetic acid, the main research area is diethylene glycol neuronal cell death neurotoxicity diglycolic acid HEAA; Diethylene glycol; Diglycolic acid; Hydroxyethoxyacetate; Neurotoxicity; SH-SY5Y cell death.

Diethylene glycol (DEG) intoxication results in metabolic acidosis, renal and hepatic dysfunction, and late-stage neurotoxicity. Though the renal and hepatic toxicity of DEG and its metabolites 2-hydroxyethoxyacetic acid (2-HEAA) and diglycolic acid (DGA) have been well characterized, the resultant neurotoxicity has not. SH-SY5Y neuroblastoma cells were incubated with all 3 compounds at increasing concentrations for 24, 48, or 120 h. At all 3 time points, 50 mmol/L DGA and 100 mmol/L DEG showed significant Annexin V and propidium iodide (PI) staining with addnl. concentrations showing similar staining patterns at 24 h (100 mmol/L DGA) and 48 h (50 mmol/L DEG, 100 mmol/L DGA). Only the 200 mmol/L 2-HEAA concentration induced SH-SY5Y cell death. Interestingly at 24 and 48 h, 100 mmol/L DEG induced significant increases in apoptotic cell death markers, which progressed to necrosis at 120 h. Similar to DEG, 50 mmol/L DGA induced significant increases in SH-SY5Y cell apoptosis and necrosis markers at both 24 and 48 h. As expected, high DGA concentrations (100 mmol/L) at 120 h induced significant SH-SY5Y cell necrosis with no apoptosis detected. However, at 120 h lower DGA concentrations (20 mmol/L) significantly increased oligonucleosome formation alone and in combination with 2-HEAA or DEG. Taken together, these results indicate that DGA and DEG at threshold concentrations induce neurotoxicity in SH-SY5Y cells.

Lee, Hyun-Jung published the artcilePerformance improvement of slot-die-deposition based perovskite solar cells using diglycolic acid additives, COA of Formula: C4H6O5, the main research area is diglycolic acid slot die deposition perovskite solar cell.

In slot-die-coating process, novel approaches for better perovskite film formation were continuously required. Here, we studied additive processes for better slot-die-processed perovskite fabrication. As a novel additive, we introduced diglycolic acid (DA) material having a carboxyl group, well known as an effective functional group. With adding optimal amount of DA in the perovskite precursor solution, device efficiency and stability were all improved; DA-based perovskite device showed the best PCE of 14.63%. Moreover, the DA-based devices showed superior long-term stability guaranteeing 80% of initial efficiency during 95 days.

Van Damme, Ryan published the artcileChemical reversible crosslinking enables measurement of RNA 3D distances and alternative conformations in cells, Synthetic Route of 110-99-6, the main research area is RNA 3D measurement reversible crosslinking cell conformation.

Three-dimensional (3D) structures dictate the functions of RNA mols. in a wide variety of biol. processes. However, direct determination of RNA 3D structures in vivo is difficult due to their large sizes, conformational heterogeneity, and dynamics. Here we present a method, Spatial 2-Hydroxyl Acylation Reversible Crosslinking (SHARC), which uses chem. crosslinkers of defined lengths to measure distances between nucleotides in cellular RNA. Integrating crosslinking, exonuclease (exo) trimming, proximity ligation, and high throughput sequencing, SHARC enables transcriptome-wide tertiary structure contact maps at high accuracy and precision, revealing heterogeneous RNA structures and interactions. SHARC data provide constraints that improves Rosetta-based RNA 3D structure modeling at near-nanometer resolution Integrating SHARC-exo with other crosslinking-based methods, we discover compact folding of the 7SK RNA, a critical regulator of transcriptional elongation. These results establish a strategy for measuring RNA 3D distances and alternative conformations in their native cellular context.
