Using a bistriazolate ligand and tetrahedral Zn(II) ion, we synthesized a flexible porous coordination polymer func-tionalized by pairs of uncoordinated triazolate nitrogen donors, which can be used as guest chelating sites to give very high CO2 adsorption enthalpy and CO2/N2 selectivity. The dynamic CO2 sorption behavior can be well monitored ...

Precision hydrodynamic controls of microparticles (e.g., microbeads and cells) are critical to diverse lab-on-a-chip applications. Microfluidic particulate-based arraying techniques are widely used; however, achieving full microarray resettability without sacrificing trapping performance has remained a significant challenge. Here we present a single-layer hydrodynamic methodology for releasing high numbers of microparticles after ...
