Here is presented a systematic study of the dispersibility of multiwall carbon nanotubes (MWCNTs) in natural rubber latex (NR-latex) assisted by a series of single-, double-, and triple-sulfosuccinate anionic surfactants containing phenyl ring moieties. Optical polarising microscopy, field emission
Personalized monitoring of therapeutic salicylic acid in dried blood spots using a three-layer setup and desorption electrospray ionization mass spectrometry.
Siebenhaar M1, Küllmer K, de Barros Fernandes NM, Hüllen V, Hopf C.
Desorption electrospray ionization (DESI) mass spectrometry is an emerging technology for direct therapeutic drug monitoring in dried blood spots (DBS). Current DBS methods require manual application of small molecules as internal standards for absolute drug quantification. With industrial standardi
A reliable and reproducible method for the lipase assay in an AOT/isooctane reversed micellar system: modification of the copper-soap colorimetric method.
The copper-soap method, which is based on the absorbance of a fatty acid-copper complex at 715 nm, is a widely used colorimetric assay to determine the lipase activity in reversed micellar system. However, the absorbance of the bis(2-ethylhexyl) sodium sulfosuccinate (AOT)-copper complex prevents th
… Silica-encapsulated ZnSe nanocrystals (NCs) were prepared by a safe and simple synthesis method, utilizing a sodium bis (2-ethylhexyl) sulfosuccinate (AOT)/water/cyclohexane microemulsion system and characterized by UV--vis analysis, photoluminescence (PL) spectroscopy, and transmission electron microscopy (TEM). …
… Temperature- and pressure-induced transitions from the charge-density-wave (CDW) phase to the Mott--Hubbard (MH) phase in the quasi-one-dimensional Br-bridged Pd compound, [Pd(en)2Br](Cn--Y)2\CdotH2O (n=4{\mbox{--}}9, and 12) (en: ethylenediamine, Cn--Y: dialkyl-sulfosuccinate), were investigated by means of crystal-structure analyses and Raman spectroscopy. …
