A paper-based SERS test strip combining strengths of paper chip and Raman active substrate was demonstrated to overcome challenges in spectroscopic sensing of complicated samples and realize quantitative detection of disease markers in whole blood. The precisely controlled Au NPs were not only capable of generating condensed hot spots on the fibers, but also enhanced the size exclusion effect of paper,...
In this work, we report a novel microfluidic gas collecting platform aiming at simultaneous sample extraction and multiplex mass spectrometry (MS) analysis. An alveolar-mimicking elastic polydimethylsiloxane (PDMS) structures was designed to move dynamically driven by external pressure. The movement was well tuned both by its amplitude and rhythm following the natural process of human respiration...
Abstract A new limit of C*-algebras, the tracial limit, is introduced in this paper. We show that a separable simple C*-algebra A is a tracial limit of C*-algebras in I(k) if and only if A has tracial topological rank no more than k. We present several known results using the notion of tracial limits.
A new limit of C*-algebras, the tracial limit, is introduced in this paper. We show that a separable simple C*-algebra $$ {\user1{\mathcal{A}}} $$ is a tracial limit of CTracial limit, Tracial topological rank*-algebras in $$ {\user1{\mathcal{I}}}^{{{\left( k \right)}}} $$ if and only if $$ {\user1{\mathcal{A}}} $$ has tracial topological rank no more than k. We present several known results...
