	1	Multifunctional polyethyleneimine for synthesis of core-shell nanostructures and electrochemiluminescent detection of three AMI biomarkers显示文摘Simplicity and stability of an analytical method are the key to practical applications.In order to achieve such a goal,a molecule with multifunction could be one of the strategies.In this work,the multifunctional characteristics of branched polyethylenemine(bPEI)were employed for verification of this hypothesis.Three types of amines in the bPEI can be used to synthesize core-shell nanostructures(bPEI@Au and SiO_(2)@bPEI@Au)in a simple one-pot process within 1 h,and as coreactants with over 500-fold enhancement for electrochemiluminescent(ECL)detection.Based on the remarkable performance of bPEI,a label-free ECL immunosensor and its array with the same assembly strategy were constructed for the simple and rapid determination of three acute myocardial infarction(AMI)biomarkers:cardiac troponin I(cTnI),human-type fatty acid binding protein(hFABP)and copeptin.Both methods exhibited excellent stability and sensitivity with wide linear range and low limits of detection down to fg/mL level by the photomultiplier tube and pg/mL level by the electron-multiplying charge-coupled device.

	2	Carbon-Involved Near-Surface Evolution of Cobalt Nanocatalysts:An in Situ Study显示文摘When carbon-containing species are involved in reactions catalyzed by transition metals at high temperature,the diffusion of carbon on or in catalysts dramatically influences the catalytic performance.Acquiring information on the carbon-diffusioninvolved evolution of catalysts at the atomic level is crucial for understanding the reaction mechanism yet also challenging.For the chemical vapor deposition process of single-walled carbon nanotubes(SWCNTs),we recorded in situ the catalyst state(solid and molten)composition as well as near-surface structural and chemical evolution at the cobalt catalyst-tube interface with carbon permeation using aberration-corrected environmental transmission electron microscopy and synchrotron X-ray absorption spectroscopy.The nucleation of SWCNTs was linked with an alternating dissolving and precipitating cycle of carbon in catalysts close to the nucleation site.Understanding the dynamics of carbon atoms in catalysts brings deeper insight into the growth mechanism of SWCNTs and facilitates inferring mechanisms of other reactions.The methodologies developed here will find broad applications in studying catalytic and other processes.
