Waheed, K. published the artcileDiglycolamide Based Mono and Di-Ionic Liquids Having Imidazolium Cation for Effective Extraction and Separation of Pb(II) and Co(II), Recommanded Product: 2,2′-Oxydiacetic acid, the main research area is lead cobalt diglycolamide ionic liquid imidazolium cation extraction separation.

Two glycolamide based functionalized ionic liquids (ILs) having imidazolium cations namely LI (mono-ionic) and LII (di-ionic) were synthesized for the extraction of Pb(II) and Co(II) from waste water. The synthesized ligands were characterized by FTIR and NMR spectroscopy. The extraction efficiency of both mono- and di-ionic liquids was evaluated in terms of contact time, pH of the aqueous phase and metal ion concentration The metal extraction was carried out at various pH values viz. 2, 4, 6, 8, and 10 whereas, at contact time of 15, 30, 45, 60, and 75 min. The optimized pH of 4 and equilibration time of 75 min was further utilized for extraction at various metal ions concentration (50, 100, 150, 200, and 250 ppm). LI exhibited low equilibration time as compared to LII whereas, both ligands showed maximum extraction at a pH of 4. A very high extraction efficiency of up to 99% for both metals was observed with LI and LII under optimized conditions. In addition to that effective separation of Co(II) and Pb(II) was observed at pH 10.

Santibanez, Luis published the artcileCuII- and CoII-based MOFs: {[La2Cu3(μ-H2O)(ODA)6(H2O)3]·3H2O}n and {[La2Co3(ODA)6(H2O)6]·12H2O}n. The relevance of physicochemical properties on the catalytic aerobic oxidation of cyclohexene, Application In Synthesis of 110-99-6, the main research area is lanthanum copper cobalt cyclohexene catalytic aerobic oxidation pore size.

The aerobic oxidation of cyclohexene was done using the heterometallic metal organic frameworks (MOFs) {[La2Cu3(μ-H2O)(ODA)6(H2O)3]·3H2O}n and {[La2Co3(ODA)6(H2O)6]·12H2O}n (LaCoODA) (2) as catalysts, in solvent free conditions (ODA, oxydiacetic acid). After 24 h of reaction, the catalytic system showed that LaCoODA had a better catalytic performance than that of LaCuODA (conversion 85% and 67%). The structures of both catalysts were very similar, showing channels running along the c axis. The physicochem. properties of both MOFs were determined to understand the catalytic performance. The Langmuir surface area of LaCoODA was shown to be greater than that of LaCuODA, while the acid strength and acid sites were greater for LaCuODA. On the other hand, the redox potential of the active sites was related to CoII/CoIII in LaCoODA and CuII/CuI in LaCuODA. Therefore, it is concluded that the Langmuir surface area and the redox potentials were more important than the acid strength and acid sites of the studied MOFs, in terms of the referred catalytic performance. Finally, the reaction conditions were also shown to play an important role in the catalytic performance of the studied systems. Especially, the type of oxidant and the way to supply it to the reaction medium influenced the catalytic results.

Zhang, Yang published the artcileHighly selective and sensitive probes for the detection of Cr(VI) in aqueous solutions using diglycolic acid-functionalized Au nanoparticles, Formula: C4H6O5, the main research area is diglycolic acid functionalized gold nanoparticle probe synthesis chromium detection.

In this study, a variety of diglycolic acid-functionalized gold nanoparticle (Au NP) probes are reported, which are highly sensitive for the detection of chromium ions, Cr(VI) ions, at low concentrations in aqueous solutions based on the application of surface plasmon resonance (SPR) theory. Due to its outstanding affinity for Cr(VI) ions, the capped diglycolic acid would induce the aggregation of the NP probes upon encountering them; this was evidenced by the obvious red-shifting of the SPR peak and the enlarged size of the NPs. For the same reason, the selectivity of the probe for Cr(VI) against other heavy metal ions was found to be remarkable. Under optimized conditions, the probe showed the limit of detection (LOD) of 0.32 ppb for Cr(VI) and a linear detection scale ranging from 0.32 ppb to 0.1 ppm. To the best of our knowledge, this is probably the lowest LOD reported for Cr(VI) detection among those of the methods based on SPR.

Nawaz, Tehreema published the artcileSynthesis of diglycolic acid functionalized core-shell silica coated Fe3O4 nanomaterials for magnetic extraction of Pb(II) and Cr(VI) ions, Category: alcohols-buliding-blocks, the main research area is diglycolic acid functionalized magnetite lead chromium adsorption magnetic WWT.

Abstract: Amine-terminated core-shell silica coated magnetite nanoparticles were functionalized with diglycolic acid for the first time to create acid moiety on the surface of the nanoparticles. The formation of magnetite nanoparticles was scrutinized through XRD, SEM, EDS, TEM, VSM and FTIR spectroscopy. The BET surface area of nano-sorbent was found to be 4.04 m2/g with pore size 23.68 nm. These nanomaterials were then utilized to remove the Pb(II) and Cr(VI) ions from their aqueous media and uptake of metal ions was determined by at. absorption spectroscopy (AAS). A batch adsorption technique was applied to remove both ions at optimized pH and contact time with maximum adsorption efficiency for Pb(II) ions at pH 7 while for Cr(VI) ions at pH 3. Adsorption mechanism was studied using Langmuir and Freundlich isotherms and equilibrium data fitted well for both the isotherms, showing complex nature of adsorption comprising both chemisorption as well as physio-sorption phenomena. The nanosorbents exhibited facile separation by applying external magnetic field due to the ferrimagnetic behavior with 31.65 emu/g saturation magnetization. These nanosorbents were also found to be used multiple times after regeneration.

Pereao, Omoniyi published the artcileAdsorption of Ce3+ and Nd3+ by diglycolic acid functionalized electrospun polystyrene nanofiber from aqueous solution, Computed Properties of 110-99-6, the main research area is cerium neodymium adsorption diglycolate functionalized electrospun polystyrene nanofiber wastewater.

Highly selective and stable ligands with fast kinetics for rare earth element extraction are not well developed. Durable attachment of ligands to the support would make regeneration possible. Polystyrene nanofiber supports (PS-nF) were prepared using the electrospinning method. Thereafter, PS-nf were chem. modified with diglycolic anhydride (DGA) to produce novel electrospun polystyrene diglycolic acid nanofiber (PS-DGAnf) adsorbents. The immobilization reaction proceeded via an electrophilic aromatic substitution of the ligand onto the PS nanofiber. The maximum gravimetric loading of DGA on PS nanofiber was 0.827 g g-1. The unmodified and modified nanofibers were characterized by ATR-FTIR, HR-SEM, BET and TGA. After optimizing pH, time and concentration, the equilibrium adsorption and binding kinetics of cerium (Ce3+) and neodymium (Nd3+) ions on the nanofibers surface were examined at pH 6. The adsorption capacity of PS-DGAnf for Ce3+ and Nd3+ at pH 6.0 was 152.5 mg g-1 (1.09 mmol/g) and 146.2 mg g-1 (1.01 mmol/g) resp. Selectivity of Ce3+ over Ni2+, Co2+ and Sr3+ was also studied at pH 6. The amount of Ce3+ adsorbed even in the presence of interfering ions was 100.3 mg g-1, which was only a little lower than 119.4 mg g-1 obtained in a single ion solution The rapid adsorption kinetics of Ce3+ and Nd3+ ions were achieved within 15 mins. The desorption and regeneration was carried out with 1 M nitric acid and the developed PS-DGAnf adsorbent could be reused for 4 cycles without any substantial loss to its adsorption abilities.

Goulart, Cristiano O. L. published the artcileAnalysis of diglycolic acid after mass poisoning by diethylene glycol, Computed Properties of 110-99-6, the main research area is diethylene glycol diglycolic acid mass poisoning analysis.

In Dec. 2019, unusual cases of acute renal failure with neurol. changes were observed in the State of Minas Gerais, Brazil. Criminal investigations indicated cases of intoxication after consumption of beers contaminated with diethylene glycol (DEG). The elimination of DEG by the body is fast, but its metabolite, diglycolic acid (DA), may persist for a long time. To assess the level of intoxicated victims who consumed the contaminated beers, qual. and quant. methods were developed to determine DA in biol. matrixes by gas chromatog. coupled to a mass spectrometer (GC-MS) and gas chromatog. coupled to a mass spectrometer with triple-quadrupole mass filter (GC-MS-MS), resp. The validated qual. method presents good selectivity and limit of detection of 1 μg/mL (whole blood, urine, vitreous humor and cerebrospinal fluid) and 5 μg/g (liver and kidney), resp. A quant. method for whole blood presented satisfactory performance to determine DA. Twelve victims presented pos. results for DA in whole blood, with concentrations ranging from 2 to 108 μg/mL. The toxicol. laboratory of the Institute of Forensic Medicine of Minas Gerais was the first governmental agency to identify DA in whole blood, vitreous humor, cerebrospinal fluid, kidney and urine in victims affected by this contaminant. The results of this study legally supported the prohibition of the continued consumption of the beer and avoided further intoxications. Our results showed, for real cases of human intoxication, that DA can still be detected in alternative matrixes, even when non-detectable in blood, demonstrating the importance of collecting different kinds of samples for a proper investigation.

Gomathi, V. published the artcileSupramolecular networks and Hirshfeld surfaces of oxydiacetic acid and iminodiacetic acid salts, Recommanded Product: 2,2′-Oxydiacetic acid, the main research area is supramol network Hirshfeld surfaces oxydiacetic acid iminodiacetic salt; Hirshfeld analysis; hydrogen bonding interactions; iminodiacetic acid; oxydiacetic acid.

Oxydiacetic acid (Oda) and iminodiacetic acid (Ida) have been combined with two diamines, namely ethylenediamine (en) and o-phenylenediamine (o-phen), to give three mol. crystals of compositions [(Oda2-)(en2+)]·H2O (Odaen), [(Ida-)(0.5en+)] (Idaen) and [(Oda-)(o-phen+)] (Odaophen). Single crystal X-ray structure determination of the three mol. salts revealed that the hydrogen bonding interactions form distinct supramol. chains. In Odaen, water mols. and Oda2- anions generate one-dimensional supramol. chains where two chains overlap each other in zigzag form. In Odaophen, Oda- anions generate a one-dimensional linear supramol. chain. In Idaen, both intermol. and intramol. proton transfer occurs. Ida- anions generate a one-dimensional zigzag chain. These one-dimensional supramol. chains extend to form different two-dimensional supramol. chains by the interaction of diaminium and monoaminium cations. Intermol. close contacts are also examined using Hirshfeld anal. to reveal similarities and differences in the crystal structures.

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.
