1-alky-3-methylimidazolium hexfluorophosphate ([n-Cnmim][PF6]) and 1-alky-3- methylimidazolium thiocyanate ([n-Cnmim]SCN) (n=4,8,16) were firstly introducing into the casting solution (PSF/NMP), porous polysulfone (PSF) membranes were successfully prepared by the wet-phase-inversion. The scanning electron microscope was utilized to visualize the cross-sections of the membranes, in order to study the influence of ionic liquids with different alkyl chain on the porous structures. The results indicate that the PSF membranes have different structures and separation properties due to ionic liquids

Abstract:

AbstractPotential biological properties of newly synthesized single and double alkyl chain N-oxides of tertiary amines (NTA) were studied. Individual compounds in each of the series had alkyl chains of different length. Various experiments were performed to determine a mechanism of the interaction between NTA and model and biological membranes. These were measurements of hemolytic efficiencies of NTA (pig erythrocytes), their influence on the transition temperatures (DPPC liposomes), on potassium leakage from cucumber, its growth and chlorophyll content (Cucumis sativus cv.

Abstract A new series of amphiphilic compounds with incorporated antioxidant functional group has been investigated. Piperidinium bromides, differing in the alkyl chain length (8, 10, 12, 14 and 16 carbon atoms in the chain) were synthesised to protect biological and/or model membranes against peroxidation and following negative consequences. Their antioxidant activity was studied with erythrocytes subjected to UV radiation. The salts used inhibited lipid oxidation in the erythrocyte membrane. The degree of this inhibition depended on the alkyl chain length of the bromide used and increased wi

Several types of N-alkyl-N,N-dimethyl quaternized chitosan (QC) derivatives with different alkyl chains were prepared as effective adsorbents towards reactive dye KN-R. QC with long dodecanyl chain was insoluble in neutral solution but could self-assembled into spherical nanoparticles. The effects of degree of quaternization and alkyl chain length on the adsorption properties of KN-R onto QC were investigated. The results showed that a higher degree of quaternization of copolymers led to a higher adsorption capacity. At similar degree of quaternization, QC nanoparticles with longer alkyl chain

Abstract:

The adsorption of a series of cationic surfactants with different chain lengths and structures on a non-swelling clay surface (sodium kaolinite) has been studied by microelectrophoresis and adsorption isotherms. It was found that an increase in the number of CH2 groups in the shorter alkyl chain of the double-chain surfactant has much less effect on the adsorption behaviour than changing the length of the alkyl chain in the single-chain surfactants. It is inferred that the effective hydrophobicity of the shorter chains in these double-chain surfactants is reduced by their intramolecular associ

Abstract:

Manipulating the length of alkyl chains is a widely-adopted strategy to fine tune the properties of organic materials. Yet, a systematic exploration of the influence of chain length on those properties most relevant to highly performing hole transport materials in perovskite solar cells is lacking. Multiscale simulations, along with morphological analyses, uncover relationships between alkyl chain length and HTM properties providing important insights for the optimization of future organic materials.

Carbon steel (CS) is the most commonly used material for equipment and pipes in the oil production processes. However, presence of water/salts and carbon dioxide, among other gases, in the oil is a serious problem due to increased corrosion rate of the material. The most common way of mitigating this problem is by using corrosion inhibitors. However, many common corrosion inhibitors that are in use today are health hazards. Therefore, there is a need to develop more environmentally compatible and biodegradable corrosion inhibitors. Bioorganic and naturally occurring molecules, such as amino ac

Abstract:

Biodiesel is a diesel-related fuel manufactured from vegetable oils, recycled grease, or animal fats. It is technically competitive with, or offers technical advantages when compared to, conventional diesel fuel. However, the freezing and gelling behaviour of many biodiesel formulations are potentially limiting their applications. It is known that the use of additives is an efficient way to improve the cold flow properties of formulated, so it is very important to clarify the mechanism and effect of additives. Molecular cluster modelling work has been explored to study the effect of additives

Amphetamine (AMPH) and its derivatives embody a remarkable breadth of pharmacology.

These transporters are electrogenic, and the transporter-mediated current can be correlated to a surrogate measure of the change in membrane voltage: Ca++ currents from co-transfected L-type Ca++ channels.

Abstract:

Silylbenzoxazine derivatives with different bulky group on benzene ring are synthesized employing aminosilane as a primary amine. The silylbenzoxazine derivatives with more bulky group exhibit low ion extraction percentage due to the difficulty of molecular assembly formation as a result of the bulky group repulsion combining with the long alkyl chain of silane. Silica surface modified benzoxazines are successfully achieved via silylbenzoxazine derivatives and show the ion extraction property for various alkali and alkaline earth metal ions. When silane is coupled onto silica, the benzoxazine
