One-pot preparation of graphene oxide magnetic nanocomposites for the removal of tetrabromobisphenol

Liqin JI, Xue BAI, Lincheng ZHOU, Hanchang SHI, Wei CHEN, Zulin HUA

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 3,   Pages 442-450 doi: 10.1007/s11783-013-0515-2

Abstract: A simple solvothermal method was used to prepare monodisperse magnetite (Fe O ) nanoparticles attached onto graphene oxide (GO) sheets as adsorbents to remove tetrabromobisphenol A (TBBPA) from an aqueous solution. These Fe O /GO (MGO) nanocomposites were characterized by transmission electron microscopy. The adsorption capacity at different initial pH, contact duration, and temperature were evaluated. The kinetics of adsorption was found to fit the pseudo-second-order model perfectly. The adsorption isotherm well fitted the Langmuir model, and the theoretical maximum of adsorption capacity calculated by the Langmuir model was 27.26 mg?g . The adsorption thermodynamics of TBBPA on the MGO nanocomposites was determined at 303 K, 313 K, and 323 K, respectively. The results indicated that the adsorption was spontaneous and endothermic. The MGO nanocomposites were conveniently separated from the media by an external magnetic field within several seconds, and then regenerated in 0.2 M NaOH solution. Thus, the MGO nanocomposites are a promising candidate for TBBPA removal from wastewater.

Talin and kindlin: the one-two punch in integrin activation

Feng Ye, Adam K. Snider, Mark H. Ginsberg

Frontiers of Medicine 2014, Volume 8, Issue 1,   Pages 6-16 doi: 10.1007/s11684-014-0317-3

Abstract:

Proper cell-cell and cell-matrix contacts mediated by integrin adhesion receptors are important for development, immune response, hemostasis and wound healing. Integrins pass trans-membrane signals bidirectionally through their regulated affinities for extracellular ligands and intracellular signaling molecules. Such bidirectional signaling by integrins is enabled by the conformational changes that are often linked among extracellular, transmembrane and cytoplasmic domains. Here, we review how talin-integrin and kindlin-integrin interactions, in cooperation with talin-lipid and kindlin-lipid interactions, regulate integrin affinities and how the progress in these areas helps us understand integrin-related diseases.
