Modifications of propylsulfonic acid-fixed Fe3O4@SiO2 with three organosilanes (C2, C8, and phenyl) were investigated to develop a magnetically separable solid acid catalyst active for hydrolysis of ethyl acetate in excess water. Among the organosilanes, triethoxy(octyl)silane was the best modif...

An efficient heterogeneous acid catalyst was developed using cenospheres, a byproduct of coal-fired thermal power plants by the method of wet impregnation. Catalyst characterization was carried out using various analytical techniques, namely, Fourier transform infrared, X-ray diffraction, field ...

Down-cycle raw material utilization is a need when it comes to the step out of fossil fuel utilization. Carboxylic acid serve as bulk chemicals, and isolation from industrial aqueous process streams is an ongoing research. Therefore acetic acid esterification of an aqueous acid feed using n-octa...

Selective functionalization of hydrocarbons remains one of the most challenging reactions in organic chemistry. With respect to terminal CH hydroxylation, electrophilic activation by late transition metals has been considered a promising route. We report the use of Shilov-chemistry inspired Pt c...

Microfibrillated cellulose (MFC) has recently been identified as an innovative product of wood and agriculture industry with potential applications as reinforcement and carrier for functional properties of polymer composite materials, such as improved barrier and optical properties. The widespre...

Well-defined decanoyl triethylene glycol ester and decanoyl tetraethylene glycol ester were synthesized and compared to their ether counterparts (C10E4 and C10E3). Their physicochemical properties i.e. critical micelle concentrations (CMC), cloud points, and equilibrium surface tensions were det...

Decay resistance of Rubber wood (Hevea brasiliensis) esterified with three fatty acid chlorides (hexanoyl chloride (C6), decanoyl chloride (C10) and tetra-decanoyl chloride (C14)) was evaluated. Unmodified and modified wood samples were exposed to a brown rot (Polyporus meliae) and a white rot (...

N-acyl amino acids-based surfactants are an attractive class of anionic amphiphiles alternative to sulphate-based surfactants, potentially employed as excipients for pharmaceutical applications in which an anionic surfactant is needed. Thus, a systematic characterization of their toxicological p...

Unsaturated fatty acids are toxic to various bacteria, causing their death or growth inhibition. To prevent this toxicity, unsaturated fatty acids should be converted into saturated fatty acids via hydrogenation reaction, which is the complete reduction of double bonds on the carbon chain. In a ...

The epoxidation of methyl oleate (MO) was conducted in the presence of aqueous H2O2 as the oxidant and hierarchical TS-1 (HTS-1) as the catalyst; the catalyst was synthesized using polyquaternium-6 as the mesopore template. The effects of various parameters, i.e., H2O2/C=C molar ratio, oxidant c...

Hydroxy fatty acids and carbonyl fatty acids are important multi-functional materials for the manufacture of fragrances and other fine chemicals. In this study, a novel oleate hydratase (PaOH) was cloned from Paracoccus aminophilus DSM 8538 and solubly expressed in Escherichia coli. The recombin...

The fatty acid methyl esters and fatty acid ethyl esters are known as biodiesels which are considered to be renewable, nontoxic and biodegradable biofuels. However, the conventional biodiesels show a high crystallization temperature which is one of the most critical obstacles against the widespr...

We determined the difference in the skin-penetration enhancing effects of conventional (C-) and super-refined (SR-) isopropyl fatty acids (IPFAs) including isopropyl myristate (IPM), isopropyl palmitate (IPP), and isopropyl oleate (IPO). In vitro permeation experiments were performed with excise...

Water/sucrose oleate + cosurfactant/oil microemulsions (MEs) were formulated for R (+)-limonene (LIM), isopropyl myristate (IPM), and caprylic-capric triglyceride (CCT) at 25°C, 37°C, and 45°C. The cosurfactants were ethanol (EtOH), propylene glycol (PG), glycerol (GLY), and propionic acid (P...

Galactitol has a melting point of 187.41 °C and a fusion enthalpy of 401.76 J g−1. Its melting temperature is not suitable for many thermal energy storage applications although it has good latent heat storage capacity compared to the several traditional phase change materials (PCMs). The galact...

Porcine ear skin is frequently used as a substitute for human skin in dermatological research and is especially useful for tape stripping experiments where the penetration of active substances into the uppermost skin layers is investigated. However, certain differences between the surface proper...

In this contribution the molecule sodium stearate (NaSt) is used for the first time as electron injection layer in combination with the fluorescent polymer phenylene substituted poly (para-phenylenevinylene) (Ph-PPV) in organic light-emitting diodes (OLEDs). The fabricated devices show current e...

Lecithin-based nanoemulsions are colloidal drug delivery systems which offer fundamental advantages in topical therapy, such as excellent skin permeation of lipophilic drugs; however, their physicochemical long-term stability is usually rather poor without the use of additional synthetic surfact...

Nanoemulsions aimed at dermal drug delivery are usually stabilised by natural lecithins. However, lecithin has a high tendency towards self-aggregation and is prone to chemical degradation. Therefore, the aim of this study was to develop nanoemulsions with improved structure and long-term stabil...

The objective of this study is to investigate the variability in physiochemical and spectral properties of commercially available vegetable-grade magnesium stearate (MgSt) samples and to assess the correlation between physiochemical properties and near-infrared and Raman spectroscopic features t...
