Li, Shasha published the artcileA nanoscale observation to explain the discrepancy of electron exchange capacities between biochar containing comparable surface redox-active moieties, Name: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is biochar nanoscale electron exchange capacity surface redox active moiety.

Biochar, possessing electron exchange capacities (EEC), is generally involved in environmental redox reactions due to the presence of redox-active moieties (RAMs). The phenomenon that chars containing comparable RAMs possess differential EEC revealed that the accessibility of RAMs is important to the redox properties. However, many studies have focused on the type of RAMs, whereas the distribution has been insufficiently investigated. Herein, we achieved nanoscale observation of electroactive moieties on the surface of six chars using a conductive at. force microscope. For the two specific kinds of chars with submicron particles and opposite current distributions, the submicron particles took up only 1-4%wt of biochar accounting for approx. 30-50% of electron-donating capacity (EDC), and electron-accepting capacity (EAC) became 87% and 1.40 times as before after removing submicron particles, resp. Meanwhile, the combined impact of RAMs and surface topog. (that uneven distribution of RAMs resulted in outstanding EEC by enhancing accessibility) was clarified. Furthermore, direct evidence of the link between char structure and EEC (that condensed aromatic structures were indispensable to EAC while both heteroatoms and amorphous aromatics contributed to EDC) was established. These findings can aid in understanding the functions of biochar in biotic and abiotic redox processes.

Mu, Xueli published the artcileHow and Why a Protic Ionic Liquid Efficiently Catalyzes Chemical Fixation of CO2 to Quinazoline-2,4-(1H,3H)-diones: Electrostatically Controlled Reactivity, Safety of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is aminobenzonitrile carbon dioxide cyclization protic IL catalyst quinazolinedione formation.

A d. functional theory study has been conducted to gain insight into the intriguing exptl. observations on the synthesis of quinazoline-2,4-(1H,3H)-diones from 2-aminobenzonitriles reacting with CO2 catalyzed by protic ionic liquids (ILs). We explored the mol. mechanism of the titled reaction, as well as the origin and catalytic nature of different ILs toward the reaction in detail. The calculated energetically viable mechanism involves CO2 attack, intramol. rearrangement, and intramol. cyclization stages. This mechanism features the initial polarization of the CN triple bond with the assistance of the real catalytic species, [HDBU+][TFECOO-], where the cation [HDBU+] acts as Bronsted acid and the anion [TFECOO-], the adduct of anion [TFE-] and CO2, acts as a nucleophile. The calculated results present the electrostatically controlled character of the reaction, where the reactivity relies on the electrostatic interaction of the IL cation with the anion. The reactivity can be controlled and regulated by the basicity of the deprotonated counterpart of the IL cation as well as the CO2 adsorption ability of the IL anion. The best catalytic performance of [HDBU+][TFE-] is attributed to its strongest basicity of the deprotonated counterpart of [HDBU+] and its most efficient CO2 adsorption property of [TFE-]. These theor. results are expected to provide guidance for designing efficient IL-based catalysts in preparing quinazoline-2,4-(1H,3H)-diones by reacting 2-aminobenzonitriles with CO2.

Skwierawska, Anna published the artcileRemoval of nonsteroidal anti-inflammatory drugs and analgesics from wastewater by adsorption on crosslinked β-cyclodextrin, Computed Properties of 42872-30-0, the main research area is nonsteroidal antiinflammatory drug analgesics removal adsorption wastewater crosslinked cyclodextrin.

We present a method using the material in the form of crosslinked β-cyclodextrin (CD) showing high efficiency in the simultaneous removal of hazardous pollutants from sewage, such as diclofenac (DIC), ibuprofen (IBU), ketoprofen (KETO), naproxen (NAPR), salicylic acid (SALI) and tramadol (TRAM). The material is stable and particularly easy to regenerate. The sorbent probably remembers the shape of the contaminants, which increases its sorption capacity after the second use. The kinetics of the KETO adsorption process from one-, two- and three-component solutions are well described by the pseudo-second-order model. The maximum polymer capacity was 162.60 mg g-1. The interactions of KETO with CD were investigated, indicating that the main sorption mechanism is based on supramol. interaction and uptake by a polymer network. The material is not sensitive to low pH and high salinity, so it can be used for the treatment of DIC, IBU, and KETO post-production wastewaters.

Mukherjee, Biswanath published the artcileSolvothermally Synthesized Iron Phthalocyanine Nanostructure for High ORR Response: A Joint Experimental Investigation and DFT Analysis, Name: Phthalonitrile, the main research area is synthesized iron phthalocyanine nanostructure ORR DFT electrochem.

In search for replacement of expensive, rare Pt based electrocatalyst towards O reduction reaction (ORR), transition metal-cored phthalocyanine (MPc) were under current research focus. Among various MPc, Fe phthalocyanine (FePc) gives best ORR performance, presumably because of its strong electron withdrawing capability. Herein, the authors report one pot solvothermal synthesis of 1 Dimensional FePc nanostructure and its possible application as ORR catalyst. The ORR performance of FePc nanostructure was carried out in 0.1M KOH (pH = 13) via cyclic voltammetry and linear sweep voltammetry. The performance, which was comparable with com. available Pt/C, measures a half wave potential (E1/2 = 0.64 V vs. RHE), onset potential (Eonset = 0.87 V vs. RHE) and electron transfer number (n) of 3.9 at 0.35 V (vs. RHE), indicating that the synthesized nanostructure essentially promote 4-electron reduction pathway. Addnl., unlike Pt/C, the synthesized nanostructure showed good MeOH tolerance. To elucidate the ORR performance from FePc, 1st principle based DFT calculation on two dimensional FePc monolayer was carried out and presented here for deeper insight. The excellent ORR activity coupled with MeOH tolerance favors the FePc nanostructure as a promising alternative to conventional Pt-based electrocatalyst for future energy storage and fuel cells.

Boughoues, Yasmine published the artcileExperimental and theoretical investigations of four amine derivatives as effective corrosion inhibitors for mild steel in HCl medium, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is amine derivative mild steel corrosion inhibition mol dynamics simulation.

Four amine derivative compounds were synthesized: 2-[(phenylamino)methyl]phenol, 2-{[(4-hydroxyphenyl)amino]methyl}phenol, 2-[(2-hydroxybenzyl)amino]benzonitrile and 2-{[(3-chlorophenyl)amino]methyl}phenol. The structure of the organic mols. was confirmed by FT-IR, 13C NMR and 1H NMR spectroscopy analyses. Their corrosion inhibition performances on mild steel in 1 M HCl were investigated using electrochem. measurements and surface anal. SEM anal. confirms the presence on the mild steel surface of a protective film of the as-prepared organic compounds, which depends on the substituent groups. Moreover, d. functional theory and mol. dynamics simulation were employed in order to determine the adsorption mechanism and the position of amine derivative mols. towards the mild steel surface in an aggressive solution and to confirm the electrochem. results. The inhibition efficiency (IE) decreases with a decrease in concentration and the adsorption obeyed the Langmuir isotherm. The substitution of the OH group on the aromatic ring by Cl or CN increases IE to 90.23 and 92.56%, resp. Mol. dynamics simulations attested that the four mols. were adsorbed on the Fe (110) surface in a flat position in the presence of water and HCl with high interaction between the different groups of the inhibitors and mild steel surface.

Bonegardt, Dmitry published the artcileHybrid materials of carbon nanotubes with fluoroalkyl- and alkyl-substituted zinc phthalocyanines, COA of Formula: C8H4N2, the main research area is carbon nanotube fuoroalkyl alkylsubstituted zinc phthalocyanine morphol humidity.

In this work, hybrid materials of single-walled carbon nanotubes (SWCNT) noncovalently functionalized with fluoroalkyl- (SWCNT/ZnPc-CF) and alkyl- (SWCNT/ZnPc-CH) substituted zinc(II) phthalocyanines were prepared The effect of fluorination of the substituents in phthalocyanine macrocycle on the functionalization degree of carbon nanotubes and sensor response to ammonia was investigated. It was shown that the type of substituents in the phthalocyanine macrocycle showed noticeable effect both on the degree of functionalization of carbon nanotubes and on the sensing performance of the investigated hybrids. The amount of phthalocyanine mols. adsorbed on SWCNT walls was shown to be 1.5 times higher in the SWCNT/ZnPc-CH hybrid. The SWCNT/ZnPc-CF layer exhibited 2 times less chemiresistive sensor response to ammonia than SWCNT/ZnPc-CH, while its sensor response was more stable at 70% relative humidity.

Korkmaz, Aysun published the artcileAsymmetric phthalocyanines conjugated on silica for the photocatalytic degradation of organic pollutants synthesis, characterization and investigation of the photophysicochemical properties, SDS of cas: 91-15-6, the main research area is phthalocyanine silica organic pollutant photocatalytic degradation photophysicochem property.

A series of novel asym. metallo (Mg, Zn and Ga) phthalocyanines were synthesized using different ratios of starting materials. After purification, these compounds were obtained in high yields. The asym. phthalocyanines were characterized by UV-visible (UV-vis), IR (IR) and 1H NMR spectroscopy, mass spectrometry (MS) and elemental anal. High solubility in organic solvents was observed because of the ester moiety at the peripheral position, and no aggregation was observed over a wide concentration range. The photophysicochem. properties of magnesium (3a), zinc (3b) and gallium (3c) phthalocyanines were examined The highest singlet oxygen quantum yield of 0.66 was obtained for 3c. The photophysicochem. measurements demonstrate clearly the potential of these asym. phthalocyanines as photocatalytic agents in the photodegradation of organic pollutants in wastewaters. The zinc complex (3b) was attached onto silica as a solid support, and photocatalytic degradation studies were carried out using Orange G to provide a typical organic pollutant.

Guezel, Emre published the artcileHigh Photosensitized Singlet Oxygen Generating Zinc and Chloroindium Phthalocyanines Bearing (4-isopropylbenzyl)oxy Groups as Potential Agents for Photophysicochemical Applications, Category: nitriles-buliding-blocks, the main research area is oxygen zinc chloroindium phthalocyanine isopropylbenzyloxy photophysicochem application.

In this study, novel phthalonitrile derivatives (1 and 2) and their peripherally and non-peripherally tetra (4-isopropylbenzyl)oxy-substituted zinc and chloroindium phthalocyanine complexes (3-6) have been prepared for the first time. The synthesized phthalonitrile derivatives and phthalocyanine complexes were characterized spectroscopically. Not only the chloroindium phthalocyanines but also zinc phthalocyanines are essentially free from aggregation in THF at the studied micromolar concentration The purpose is to compare the effects of two types of substitution on the phthalocyanines to be used as sensitizers in photodynamic therapy (PDT). Photophys. and photochem. properties of all phthalocyanines are investigated and the results showed that the peripheral phthalocyanines more effectively photooxidize DPBF through singlet oxygen. The photochem. results showed that both ZnPc (3 and 5) and InPc (4 and 6) can be used as sensitizers in PDT because of their very high singlet oxygen quantum yields (range from 0.80 to 0.97).

Araghi, Mohammad Esmaeil Azim published the artcileThermal and Temporal Properties of a Thin Layer of Bromo Indium Phthalocyanine Nanostructures, Safety of Phthalonitrile, the main research area is bromo indium phthalocyanine nanostructure thermal temporal property.

In this work, we report on the synthesis, fabrication, and elec. and optical characterization of sandwich devices of bromo indium phthalocyanine thin film nanostructures in aluminum electrodes using electron beam evaporation in a high vacuum which have the potential to be used for sensing applications. The study investigate the influence of both parameters of temperature and frequency on the conduction mechanism to determine the transport process in the carriers. Results demonstrate that the capacitance, dielec. constant and loss factor decrease with increasing the frequency and increase in high temperatures The behavior of capacitance and loss factor fits well with the model of Goswami and Goswami and the results imply the domination of hopping theory. In addition, anal. of the absorption spectrum indicates that the optical band gap energy is 3 eV. Furthermore, morphol. anal. demonstrates that all films have a smooth surface with homogeneous small crystal grains with a nanoscale size order of 40 ± 10 nm. Thus, temperature and frequency-dependent experiments of optical and elec. parameters of the bromo indium phthalocyanine thin film nanostructures show their potential to be employed for sensing applications.
