Adipic acid is an important dicarboxylic acid mainly used for the production of nylon 6–6 fibers and resins. Previous studies focused on the biological production of adipic acid directly from different substrates, resulting in low yields and titers. In this study, a five-step reverse adipate-de...

In this study, blends of poly (butylene succinate-co-adipate) (PBSA) and raw hydrolyzed collagen (HC), a byproduct of the tannery industry, were investigated in terms of processing by blown film extrusion/injection molding and thermal/rheological/mechanical properties. PBSA/HC blends were prepar...

The linear polyester poly(glycerol adipate) (PGA) with its free pendant hydroxyl groups was covalently grafted with indomethacin which yields polymeric prodrugs. It was possible to produce nanospheres with narrow particle size distribution of these polymer-drug conjugates with an optimized inter...

Acetylated maltodextrins (AMDs) were synthesized. It was found that maltodextrin (MD) was easily acetylated to form AMDs with high degree of substitution (DS). The DS of the prepared AMDs was much higher than that of acetylated corn starches (ACSs) obtained under the same reaction conditions. Th...

Polyurethane (PU) di-block copolymers are one of the most versatile polymeric materials, comprised of hard and soft segments that contribute to PU's broad range of applications. Polybutylene adipate (PBA) is a commonly used soft segment in PU systems. Characterizing the structure of PBA pol...

The linear biodegradable polyester poly(glycerol adipate) (PGA) was synthesized via enzymatic polycondensation using lipase B from Candida antarctica (CAL-B). Every monomer unit of PGA possesses a pendant hydroxyl group which is responsible for the hydrophilic character and moisture swelling. Th...

The solubility measurements of sodium dicarboxylate salts; sodium oxalate, malonate, succinate, glutarate, and adipate in water at temperatures from (278.15 to 358.15 K) were determined. The molar enthalpies of solution at T = 298.15 K were derived: ΔsolHm (m = 2.11 mol · kg−1) = 13.86 kJ · m...

Cobalt adipate tetrahydrate single crystals were grown by the single gel diffusion technique. The well-faceted, red-colored crystals were characterized by single crystal X-ray diffraction analysis, Fourier-transform infrared spectroscopy and micro-Raman spectroscopy. The single-crystal X-ray dif...

This work represents the results of detailed studies on cobalt(II) extraction from chloride solutions by 1-(2-pyridyl)tridecan-1-one oxime. The obtained results show that extraction of cobalt(II) ions strongly depended on pH, contact time and concentration of extractant, cobalt(II) and chloride ...

A series of 15 novel 1,3,4-thiadiazole amide derivatives containing a protocatechuic acid moiety were synthesized and structurally characterized. In addition, the corresponding imino (4) and amino (5) analogues of a phenyl-substituted 1,3,4-thiadiazole amide derivative 3a were prepared to compar...

The chemical recycling of waste poly(ethylene terephthalate) (PET) using castor oil (CO) as a reagent is reported. CO presents a renewable alternative to petrochemical based reagents, e.g. glycols, and enables also substantial modification of final physico-chemical properties of a received produ...

Grafting of activated MIL-100(Cr) with EG (ethylene glycol), DEG (diethylene glycol), TEG (triethylene glycol) and EN (ethylenediamine) leads to a decrease of the BET surface area and pore volume. Yet, water adsorption isotherms of the modified compounds MIL-100(Cr)-EG, MIL-100(Cr)-DEG and MIL-1...

The convective heat transfer performance and energy efficiency of Al2O3/DI-water and CuO/DI-water nanofluids flowing through a straight vertical tube was experimentally studied for laminar, transitional and turbulent flow regimes. A circulating rig was built to conduct the experiments at constan...

The microwave spectrum of a dideuterated form of ethylene glycol (glycol-O-d2, CH2ODCH2OD) has been investigated in the frequency range from 18 to 50 GHz. Among the many transitions observed, 64 rotational transitions could be assigned with the help of microwave—microwave double resonance exper...

Triacylglycerol monohydroperoxides (TG-mHPO) were selectively detected at the picomole levels after post-column reaction with diphenyl-1-pyrenylphosphine (DPPP). TG-mHPO were separated on two types of reserved-phase columns, an ODS column and a phenylated silica gel, column which were useful for...

Publisher SummaryUnsaturated fatty acids and their esters are oxidized to produce hydroperoxides at the initial stage of the peroxidation. Recently, hydroperoxides have attracted much attention as one of the factors that might be associated with some diseases and aging. Several methods have been...

Diphenyl-1-pyrenylphosphine (DPPP), which reacts with lipid hydroperoxides stoichiometrically to yield fluorescent product DPPP oxide, was used as a fluorescent probe for lipid peroxidation in live cells. DPPP was successfully incorporated into U937 cells. Incorporation of DPPP into the cell mem...

Diphenyl-1-pyrenylphosphine (DPPP), which reacts with lipid hydroperoxide stoichiometrically to yield a fluorescent product DPPP oxide (DPPPO) and the corresponding hydroxide, was used as a fluorescent probe for lipid peroxidation in low-density lipoprotein (LDL). DPPP was successfully incorpo...

3,5-Dihydroxy-4-methoxybenzyl alcohol (DHMBA), an antioxidant isolated from the Pacific oyster (Crassostrea gigas), was studied in a cell-based fluorometric antioxidant assay using human hepatocyte-derived cells (C3A) and diphenyl-1-pyrenylphosphine (DPPP) as a fluorescent probe. In comparison w...

Diphenyl-1-pyrenylphosphine (DPPP) was tested whether it could be used as a fluorescent probe to monitor lipid peroxidation in cell membranes. DPPP reacted with organic hydroperoxides and hydrogen peroxide stoichiometrically to give DPPP oxide (DPPPO). DPPP incorporated into phosphatidylcholin...
