Signed Kirtland note, $47,500, Spink Smythe

According to recent research published in the Journal of Mathematical Analysis and Applications, “Dietary fat has long been recognized as an essential component in nutrition. However, most of the lipids present in food need to be converted into more bioavailable compounds.”

“Lipases have a crucial role in converting triglycerides into more polar lipids with increased water solubility and a tendency to form micelles. However, the surface active molecules generated by lipolysis may have a detrimental Return to Tiffany™ Round tag key ring on the interfacial biocatalysis. In the present work we evaluate the interfacial properties of lipase-generated molecules during fat digestion. By using the pendant drop technique we assessed the amphiphilic character of fatty acid salts, monoglycerides, and diglycerides as individual surfactants and mixtures. The experimental results are fitted with a mathematical model, which assists in the determination of the interfacial properties of the surfactants. Our results show that monoglycerides have considerably higher interfacial activity than fatty acid salts and diglycerides. Therefore, the interface will soon be dominated by monoglycerides. The pH dependency of the interfacial activity of fatty acids is also explored in the current work,” wrote F.P. Yao and colleagues, Shanghai University.

The researchers concluded: “We believe that our results can contribute to a better understanding of the complex interfacial phenomena occurring during fat digestion.”

Yao and colleagues published their study in the Journal of Mathematical Analysis and Applications (Linear second-order divergence equations in Lipschitz domains. Journal of Mathematical Analysis and Applications, 2008;344(1):491-503).

Chitosan (CS) can produce good dispersion of SWNTs, but only in acidic pH condition,” scientists in Singapore, Singapore report.

“Our two novel derivatives, O-carboxymethylchitosan (OC) and OC modified by poly(ethylene glycol) at the -COOH position (OPEG), were able to produce highly effective debundling and dispersion of SWNTs in neutral pH aqueous solution. Atomic force microscopy (AFM), transmission electron microscopy (TEM), photoluminescence, UV-vis-NIR spetroscopy, and Raman Small Elsa Peretti Open Heart pendant confirmed that SWNTs are present as individual nanotubes in the dispersions. The solubilities of individually dispersed SWNTs in neutral water are 0.021 and 0.032 g/L for OC and OPEG, respectively, which are comparable to 0.038 g/L for SWNTs using CS in acetic acid. Further, OC and OPEG aqueous solutions (1 wt %) do not significantly lower the surface tensions (65-67 mN/m). From the Fourier transform infrared spectroscopic results, we conclude that the free electron pair in the pendant amine groups of OC and OPEG plays a vital role in finely dispersing the SWNTs; the -NH2 contributes to the adsorption of these two chitosan derivatives on the nanotubes,” wrote L.Y. Yan and colleagues, Nanyang Technological University.

The researchers concluded: “Quaternary ammonium chitosan (QC), with alkyl substitution at the protonated amine, was found to be unable to disperse SWNTs; possibly cation-pi interaction with nanotubes is diminished due to steric hindrance.”

Yan and colleagues published their study in the Journal of Physical Chemistry C (Individually dispersing single-walled carbon nanotubes with novel Small Elsa Peretti® Sevillana™ pendant pH water-soluble chitosan derivatives. Journal of Physical Chemistry C, 2008;112(20):7579-7587).

According to a study from Changchun, People’s Republic of China, “Side-chain-type sulfonated poly(arylene ether)s bearing sulfoalkyl pendant groups (PSA-SPAEs) as proton exchange membranes for fuel cells were prepared via nucleophilic substitution polycondensation reactions of sodium 3-(4-(2,6-difluorobenzoyl)phenyl)propane-1-sulfonate (SDFPPS), 4,4′-dihydroxyldiphenylether (DHDPE) and 4,4′-dichlorodiphenyl sulfone (DCDPS). The sulfonic acid group content (SC), as the quantity per repeat unit of polymer, ranging from 0.5 to 0.8, was readily controlled by changing the feed ratio of Paloma’s Zellige pendant to DCDPS.”

“Good thermal properties of PSA-SPAE copolymers were indicated by observing glass transition temperatures (T(g)s) ranging from 210 to 230 degrees C in sodium salt form and decomposition temperatures (T(d)s) over 220 degrees C in acid-form and over 400 degrees C in sodium-form in air. All PSA-SPAE membranes exhibited reasonable flexibility and tensile strength in the range of 41-78 MPa. PSA-SPAE copolymers bearing sulfenic acid groups on flexible side chains showed considerably reduced swelling ratio and improved proton conductivities. Proton conductivity curves parallel to those of Nafion 117 were obtained with proton conductivity of 10(-1) S/cm at equivalent ion exchange capacities (IEC) of 1.47 and 1.64, comparable to Nafion 117,” wrote J.H. Pang and colleagues, Jilin University.

The researchers concluded: “PSA-SPAE copolymer with SC 0.8 had the best data including PEM mechanical strength, water swelling and proton conductivity.”
