The effective detection of dichloromethane (DCM) was performed by hexagonal zinc oxide (ZnO) nanopyramids (NPys) modified disposable screen printed electrode (SPE) for the fabrication of reproducible, highly sensitive and reliable chemical sensors. ZnO NPys were synthesized by a simple hydrother...
Based on first-principles density functional theory (DFT), the capture and dissociation of dichloromethane (CH2Cl2) on Fe, Ni, Pd and Pt decorated phosphorene have been investigated. The results show that all the four metal decorations can enhance the capture ability of phosphorene to CH2Cl2, an...
Enzymatic electrolysis cell (EEC) has advantages over microbial electrolysis cell (MEC) due to the needless of microbe inoculation and high-efficiency of enzymatic reaction. In this study, an EEC was first applied to achieve the effective degradation of halogenated organic pollutants and dichlor...
The kinetics of the gas-phase reactions of chlorine atoms with dichloromethane (CH2Cl2) and D-dichloromethane (CD2Cl2) was studied using the relative rate method with Cl + CH3Br as the reference reaction. The rate constants for H-abstraction from CH2Cl2 (kH) and D-abstraction from CD2Cl2 (kD) we...
Measurements of spin-lattice relaxation, combined with 2D measurements of single- and double-quantum spin-echo decay rates, have been used to determine the complete set of spectral density parameters which characterize deuterium relaxation of CD2Cl2 partially oriented in a nematic liquid crystal...
Precise and accurate values of the excess enthalpies of{xC6H6 + (1 − x)C6D6} ,{xC6H12 + (1 − x)C6D12} and{xCH2Cl2 + (1 − x)CD2Cl2} have been determined over the whole composition range at T = 298.15 K. Although all the excess enthalpies are small, those of{xC6H6 + (1 − x)C6D6} and{xC6H1...
Using CO2 and N2O lasers, we have measured and assigned nineteen ν4 and nine ν6 rotation-vibration resonances of the type ΔM = 0 and M = J. These transitions were combined with the zero-field pure rotational spectra in order to determine the two fundamental vibrational frequencies, the rotati...
The radiationless transitions of isolated D2CO in rare gas and N2 hosts near 4.2 K have been investigated with tunable ultraviolet excitation. n—π* fluorescence occurs without an appreciable host-induced phosphorescence. A1A2 T3 blue-shift of 140 ± 20 cm−1 occurs in neon host, without an appr...
The vapor-phase MCD spectrum of formaldehyde-d2 is reported. Several new triplet bands are identified and a partial analysis of the singlet system is given.
The differential separation of deuterated and non-deuterated forms of isotopically substituted compounds in chromatography is a well-known but not well-understood phenomenon. This separation is relevant in comparative proteomics, where stable isotopes are used for differential labelling and the ...
High-resolution Fourier transform infrared spectrum of the ν2 band (1590–1780 cm−1) of deuterated formaldehyde D2CO has been recorded. More than 2500 rovibrational transitions have been assigned up to Jmax = 52 and Kmaxa = 17. The upper state v2 = 1 (A1) was found to be perturbed by a ΔKa = 2...
Second harmonic generation excited by Nd:YAG laser (λ=1.32μm) was observed during the investigation of second-order optical poling process in 1-H-pyrazolo[3,4-b]quinolines chromophores incorporated within the oligoether acrylate (OEA) photopolymer matrices. We have found that the observed SHG ...
A Pd-catalyst with benzothiazole carbene as ligands allows, in tetrabutylammonium bromide melt as solvent, very fast and efficient reactions of haloaromatics with β-substituted acrylates.
As strategies for manipulating cellular behaviour in vitro and in vivo become more sophisticated, synthetic biomaterial substrates capable of reproducing critical biochemical and biophysical properties (or cues) of tissue micro-environments will be required. Cytoskeletal tension has been shown t...
A photocurable acrylate matrix nitrate-sensitive membrane containing 2-nitrophenyl n-octyl ether as mediator and tetraalkylammonium nitrate as an active compound is described. The photocuring was achieved by the use of photoinitiators containing diaryliodonium chloride. This acrylate membrane is...
The enzymatic phosphorylation of phenoxyethanol, 2-hydroxyethyl acrylate and 4-hydroxybutyl acrylate catalyzed by acid phosphatases PhoN-Sf and PiACP at the expense of inorganic di-, tri-, hexameta- or polyphosphate was applied to the preparative-scale synthesis of phosphorylated compounds. The ...
Various acrylates [E-phenylpropenoate, E-3(4′-nitrophenyl)propenoate, E-3(2′,5′-difluorphenyl)propenoate, E-3(2′-thienyl)propenoate, E-3(4′-imidazolyl)propenoate or E-2,3-dimethylpropenoate] were successfully intercalated into Ca(II)Fe(III) layered double hydroxide (CaFe–LDH) verified by a...
The organic amine 3-Amino-3-(2-nitrophenyl) propionic acid (3-ANPPA) was characterized by spectroscopic profiling employing FT-IR, FT-Raman and UV–Visible spectra both experimentally and theoretically. In addition, the bonding and anti-bonding nature, nonlinear optical, electronic and thermodyn...
An amperometric immunosensor for the determination of the hormone insulin-like growth factor 1 (IGF1) is reported for the first time in this work. As electrochemical transducer, a multiwalled carbon nanotubes-modified glassy carbon electrode on which poly(pyrrole propionic acid) was electropolym...
2,7-Diethylamino-2-oxo-2H-chromen-3-yl benzothiazole-6-sulfonyl chlorides dye (Coumarin 6-SO2Cl) was used to synthesize anilines and amino acid derivatives.The electronic absorption and emission spectra of the label and its derivatives in organic solvents of different polarity, micellar systems ...
