Kaolin was modified with a solution of phosphorylated cashew nut shell liquid prepolymer (PCNSL) containing hexamethylenediamine (HMDA). The organomodified kaolin was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and infrared sp...
A bifunctional N-glycoside namely N,N′-Diglycidyl-1,6-hexanediamine (DHA) was synthesized by the facile reaction of 1,6-hexamethylene diamine and glucose and its corrosion inhibition behavior was evaluated on copper in 3.5% NaCl solution for the first time. A detailed electrochemical study usin...
In order to study the self-crosslinking mechanism of an acrylic-based copolymer emulsion, the stable, one pack (1 K), room temperature curing copolymer was synthesized by semi-continuous seeded emulsion polymerization using butyl acrylate (BA), styrene, acrylic acid (AA), acrylamide and allyl ac...
In this work, a new experimental data of CO2 solubility in aqueous solution of Hexamethylenediamine (HMDA) have been generated at 30, 40, 50 and 60 °C in the CO2 partial pressure range of 1–100 kPa. Concentration of aqueous HMDA used for solubility measurement ranges from 10 to 30 mass%. Elect...
Equilibrium solubility and absorption kinetics of CO2 in hexamethylenediamine (HMDA) activated aqueous sodium glycinate (SG) solvent are measured in the temperature range of 313–333 K. For the experimental investigation, HMDA concentration in the solvent is varied in the range of 5–15 mass% ke...
In this work, kinetics of CO2 absorption in aqueous hexamethylenediamine (HMDA) has been investigated in the temperature range of 30–60 °C using a reaction calorimeter. Aqueous solutions of HMDA studied in this work are 5, 10, 20 and 30 mass%. Physicochemical and transport properties such as d...
This paper describes the kinetics of particle growth of boehmite under hydrothermal conditions in the presence of octanoic acid. The size of the boehmite particles formed after hydrothermal treatment between 200 and 400 °C in a batch reactor was measured after various treatment times (several m...
Olfactory receptors (ORs) are G protein-coupled receptors that mediate olfactory chemosensation, leading to the perception of smell. ORs are expressed in many tissues, but their functions are largely unknown. Here, we show that the olfactory receptor Olfr15 is highly and selectively expressed in...
Ester products, obtaining from guaiacol and octanoic acid which were the degeneration products of lignin, were tested over sulfonic acid-functionalized SiO2 materials. The results showed that the functionalized mesoporous SiO2 had a high activity and stability, resulting in ester yield of 62%. T...
Crystal growth behaviors of boehmite particles with octanoic acid and sodium octanoate under supercritical hydrothermal condition were investigated. It was confirmed that adding carboxylic acid is effective in synthesizing hexagonal plate particles with high aspect ratios, while rhombic plate pa...
Considering the low thermal conductivity of organic phase change materials (PCMs), a modification of Octanoic acid (OA) and Myristic acid (MA) binary mixture with a mass ratio of 87:13 was studied. The influence of expanded graphite (EG) and Hydroxylated multi-walled carbon nanotubes (MWCNTs) on...
A series of Ni located on hollow spherical ZrO2 catalysts was prepared, and their catalytic performances for octanoic acid deoxygenation were investigated. The ZrO2 hollow spheres saturated by the water phase served as a nanoreactor that captured octanoic acid to react with Ni located inside a h...
BackgroundParkinson’s disease (PD) is a progressive neurodegenerative process leading to the loss of dopaminergic neurons and their projections. 1-methyl-4-phenol-1,2,5,6-tetrahydropyridine (MPTP) toxicity is a well-recognized animal model of PD. It is suggested that the impairment of mitochond...
We investigated the antimicrobial efficacy of octanoic acid (OA) against Escherichia coli O157:H7 inoculated on the surface of baby spinach and grape tomatoes during simulated washing processes. 3 mM OA at 45 °C achieved >6 log CFU/g reduction from the surface of tomatoes within 2 min. However,...
ObjectiveTo investigate the effect of octanoic acid (OA) on the peripheral component of tremor, as well as OA’s differential effects on the central and peripheral tremor component in essential tremor (ET) patients.
The present proof-of-concept study reports the construction of a whole-cell biocatalyst for the de novo production of ω-hydroxy octanoic acid. This was achieved by hijacking the natural fatty acid cycle and subsequent hydroxylation using a specific monooxygenase without the need for the additio...
Dicarboxylic acids are an important source of information about metabolism and potential physiopathological alterations in children with autism spectrum disorders (ASDs). We measured the concentration between dicarboxylic adipic and suberic acids in children with an ASD and typically-developing ...
Adipic acid (AA) is an important dicarboxylic acid used for the manufacture of nylon and polyurethane plastics. In this study, a novel adipic acid biosynthetic pathway was designed by extending the cis,cis-muconic acid (MA) biosynthesis through biohydrogenation. Enoate reductase from Clostridium...
SummaryAtomic layer deposition (ALD) improves the durability of metal catalysts using nanoscale metal oxide coatings. However, targeted coating strategies and economic models are lacking for process-specific deactivation challenges that account for implications at scale. Herein, we apply Al2O3 A...
Adipic acid is an important industrial chemical used in the synthesis of nylon-6,6. The commercial synthesis of adipic acid uses petroleum-derived benzene and releases significant quantities of greenhouse gases. Biocatalytic production of adipic acid from renewable feedstocks could potentially r...
