In this work, we successfully developed electromembrane extraction via preparation of an electrospun flat membrane based on device. The polyurethane-membrane was prepared by electrospinning method and used in EME. Affecting parameters on membrane preparation were optimized by Taguchi design. The developed method was used for extraction of phthalates as typical molecules and the proposed method ...
Molecular oxygen can replace sacrificial olefins as the hydrogen acceptor in the palladium trifluoroacetate catalyzed dehydrogenation of cyclohexene and related cyclic olefins into aromatics. One of the major drawbacks of the homogeneous system is the tendency of the palladium trifluoroacetate to precipitate as palladium(0) at elevated temperatures. The use of better ligands affords catalysts t...
A colorimetric and fluorescent dual probe for palladium species was rationally developed by combining the resorufin fluorophore with allyl chloroformate. The probe enables the visual detection of palladium based on its vivid color change from pale yellow to pink and its fluorescence off-on response to palladium in PBS solution. The detection limit was calculated to be as low as 2.1 nM. The live...
Palladium is frequently used in dental materials, and sometimes causes metal allergy. It has been suggested that the immune response by palladium-specific T cells may be responsible for the pathogenesis of delayed-type hypersensitivity in study of palladium allergic model mice. In the clinical setting, glucocorticoids and antihistamine drugs are commonly used for treatment of contact dermatitis...
