2-methylphenoxyacetic acid (2-MPA), 2-methyl-4-chlorophenxyacetic acid (MCPA) and 4-chlorophenoxyacetic acid (4-CPA) were imprinted to investigate the cross-selectivities of molecularly imprinted polymers (MIPs). The result indicates that 2-MPA, which is similar in shape, size and functionality with phenoxyacetic herbicides, are suitable to be used as a suitable template to prepare the MIPs for retaining phenoxyacetic herbicides. To study the ion-pair interactions between template molecules and functional monomer 4-vinylpiridine (4-VP), computational molecular modeling was employed. The data indicate that the cross-selectivities of MIPs for phenoxyacetic acid herbicides depend on the binding energies of complexes.

Acute poisoning with chlorophenoxy herbicides such as 2,4-D and MCPA is reported world wide, potentially causing severe toxicity and death. Since there is no antidote for chlorophenoxy herbicides, treatments such as urinary alkalinisation have been used to increase the clearance of these poisons from the body. Although urinary alkalinisation was first trialled over 30 years ago, it is not currently used routinely for the treatment of patients with acute chlorophenoxy poisoning. This review looked for studies where this treatment had been given to poisoned patients. No studies of sufficient quality were identified and therefore routine use of this approach to treatment cannot be recommended. However, due to the poor outcomes in patients who present with severe toxicity it may have a role in addition to standard intensive care support. More research should be conducted.. ...

Most machine learning research on chemical systems study either materials, with periodic structures, or molecules. Often for surface catalysis, the relevant information is in-between both systems. For this study, our dataset contains molecules on different surface defects, namely catalytic active centres. These are N-doped graphene pores supporting one or two single metal atoms.. The binding energies (BE) is an indicator for the strength of the interaction of the molecule with the surface and is used as the label. The data includes around 1600 structures of molecules on various different active centres and their BE. The geometric data comprises of the 3-dimensional coordinates of all atoms in a periodic cell. The main problem is describing features which are meaningful for a wide number of structures, as different structures have different atom types, adsorbed species and number of atoms. Through different descriptions of the geometrical structure in the systems, we try to link the BE to ...
Chlorophenoxy herbicides are a class of herbicide which includes: MCPA, 2,4-D, 2,4,5-T and mecoprop.[1] Large amounts have been produced since the 1950s for agriculture.[2] Acute toxic effects after oral consumption are varied and may include: vomiting, abdominal pain, diarrhoea, gastrointestinal haemorrhage acutely followed by coma, hypertonia, hyperreflexia, ataxia, nystagmus, miosis, hallucinations and convulsions.[3] Treatment with urinary alkalinization may be helpful but evidence to support this practice is limited.[1][3] ...
The density functional theory (DFT) calculations were used to get information concerning the interaction of curcumin with pristine and N-doped TiO2 anatase nanoparticles. Three adsorption geometries of curcumin over the TiO2 anatase nanoparticles were studied in order to fully exploit the sensing properties of TiO2 nanoparticles. Curcumin molecule adsorbs on the fivefold coordinated titanium sites of the TiO2 nanoparticle because of the higher affinity of these sites with respect to the curcumin molecule. A preferred perpendicular adsorption of curcumin on the OC-substituted nanoparticle was found to be the most favorable conformation with the estimated adsorption energy of about -5.33 eV. The results suggest that the curcumin molecule favorably interacts with the N-doped TiO2 nanoparticle, that is, the interaction of curcumin with the pristine nanoparticle is less favorable in energy than the interaction with the N-doped one. The structural parameters such as bond lengths/angles and adsorption energies

Dichlorprop possesses a single asymmetric carbon and is therefore a chiral molecule, however only the R-isomer is active as an herbicide. When dichlorprop was first marketed in the 1960s, it was sold as racemic mixture of stereoisomers, but since then advances in asymmetric synthesis have made possible the production of the enantiopure compound. Today, only R-dichlorprop (also called dichlorprop-p or 2,4-DP-p) and its derivatives are sold as pesticides in the United States. Dichlorprop is a carboxylic acid, and like related herbicides with free acid groups, it is often sold as a salt or ester. Currently, the 2-ethylhexyl ester is used commercially. The butoxyethyl and isooctyl esters were once popular, but are no longer approved for agricultural use. For the salts, the dimethylamine salt is still available, while the diethanolamine salt is no longer used. According to the United States Environmental Protection Agency (EPA), "2,4-DP-p is thought to increase cell wall plasticity, biosynthesis of ...

Hierarchical N-doped TiO2 microspheres with exposed (001) facets [N-TiO2-(001)] were synthesized through a simple, fluorine-free solvothermal reaction with subsequent thermal treatment. The results show that the hierarchical N-TiO2-(001) microspheres are made up of numerous TiO2 nanosheets, and that isopropylamine (IPAN) acts as both the nitrogen source and the capping and shape-controlling agent that generates the high-energy (001) facets. In addition, IPAN is also effective in increasing the onset temperature of the phase transformation of TiO2 from anatase to rutile. Compared with the commercially available P25 TiO2, the as-prepared TiO2 microspheres exhibit good photocatalytic activity and high stability under visible-light irradiation. The high photocatalytic performance is derived from the synergy effect of N-doping and the separation of photogenerated electrons and holes among different facets, as evidenced by surface photovoltage spectroscopy. ...

Ternary PtRuNi nanocatalysts supported on N-doped carbon nanotubes: deposition process, materials characterization, and electrochemistry
This work shows that N-doped carbon can be derived from pyrrole modified biomass-lignin. Simultaneous chemical and physical activation using potassium hydroxide during the heat treatment can effectively create porous N-doped carbon. The activated carbon possesses cheese-like morphology with large specific surface area of 2661 m2 g-1 and mesopores of ~15 nm. Benefited from these characteristics, EDLCs prepared using the N-doped porous activated carbon show high specific capacitance of 248 F g-1 at low current density of 0.1 A g-1 and 211 F g-1 at high current density of 10 A g-1 in 6 M KOH solution. The EDLCs also exhibit excellent cycle stability for continuous 1,000 cycles at different current densities. This work indicates that the pyrrol-modified KOH-activated lignin is a promising electrode material for EDLCs.
A number of acylthioureas, 2-((4-methylphenoxy)methyl)-N-(aryl-carbamothioyl)benzamides (aryl = 3,5-dichlorophenyl, 2,3-dichlorophenyl, 3,4-dichloro-phenyl, 2,4,5-trichlorophenyl, 3,4,5-trichlorophenyl, 2-bromophenyl, 2,4-dibromophenyl, 2,5-dibromophenyl, 2-iodophenyl, 3-fluorophenyl, 2,3,4-trifluorophenyl, 2,4,5-trifluoro-phenyl, 2,4,6-trifluorophenyl) have been synthesized, characterized by elemental analysis, IR and NMR spectroscopy and tested for their interaction with bacterial cells in free and adherent state. The anti-pathogenic activity was correlated with the presence of one iodine, bromide or fluorine, and two or three chloride atoms on the N-phenyl substituent of the thiourea moiety, being significant especially on Pseudomonas aeruginosa and Staphylococcus aureus strains, known for their ability to grow in biofilms. Our results demonstrate the potential of these derivatives for further development of novel anti-microbial agents with antibiofilm properties.

My best guess is you are interpreting the statement "inductive effect decreases as the length of alkyl group increases" somewhat out of context.. So, lets compare formic acid to acetic acid. Formic acid has hydrogen bonded to the carbonyl, while acetic acid has a methyl group. The methyl group is inductively donating, and as a result acetic acid is less acidic than formic acid. $p_{Ka}$ difference of $1$ full unit.. So now, let us compare methyl acetic acid (a precise, but incorrect, alternate name for propanoic acid) to acetic acid. Methyl acetic acid has an inductive donating group at the $\ce{CH2}$ carbon. As such, we expect some donation, and a lower acidity for methyl acetic acid as compared to acetic acid. True, the donating group is one group removed from the acidic site, which means the effect of the methyl group on methyl acetic acids acidity is diminished as compared to an electron donating group directly attached to the carbonyl, so the acidity reduction will be smaller. $p_{Ka}$ ...
