New material for optically detectable drug carriers

Room-temperature phosphorescence from mesoporous silica is observed, with the emission persisting for seconds after switching off the excitation.

metal-activator-free phosphorescenceSuch mesoporous silica materials, including both powders and monoliths, with strong phosphorescence could find promising applications as low-density and eco-friendly phosphors and optically detectable drug carriers.

Modelling chiral polymerization

HOT paperread it first!

This PCCP paper numerically solves a kinetic model of chiral polymerization in systems closed to matter and energy flow.

Chiral polymerization: symmetry breaking and entropy production in closed systems
Celia Blanco and David Hochberg
Phys. Chem. Chem. Phys., 2011, DOI: 10.1039/C0CP00992J

They demonstrate that a strong chiral amplification can take place in a reversible model of chiral polymerization closed to matter flow and subject to constraints imposed by micro-reversibility.

These results are important, because they suggest that spontaneous mirror symmetry breaking in experimental chiral polymerization can take place, and with observable and large chiral excesses, without the need to introduce chiral initiators or large initial chiral excesses.
