Plasmons for Energy Conversion

The surface plasmon phenomenon of metal nanoparticles has remained an active area of research in nanoscience. Of particular current interest is its role in influencing energy conversion processes. The fundamental aspects of plasmonic (Au, Ag, or Al) nanoparticles of different sizes and shapes have been extensively investigated to understand their role in light energy harvesting assemblies, catalysis, photocatalysis, and solar cells. Of particular interest is the electric field created by plasmons at the surface under selective excitation with photons, which significantly enhances the performance of catalytic or photoinduced processes. This virtual issue is a collection of Perspectives, Reviews, and research articles published in ACS Energy Letters, The Journal of Physical Chemistry Letters, The Journal of Physical Chemistry C, and The Journal of American Chemical Society that highlight recent developments in employing plasmons for energy harvesting. The papers included in this virtual issue cover key topics ranging from fundamental aspects of plasmon dynamics to the use of plasmons to increase the performance of photovoltaic solar cells and solar fuels generation.

Extracting More Information Using Less

Topics presented at the 2017 ISCC and GC × GC symposia and published in Analytical Chemistry in 2017 through May 2018 are featured in this virtual issue. The emphasis on separations (e.g., LC, CE, GC, ion mobility, chips, etc.) and mass spectrometry is apparent, as is the coupling of two or more of these techniques. Enhanced performance has come from altering and improving instruments or parts of instruments, novel coupling strategies, data treatment, and sample preparations. The enhanced capabilities of newly developed techniques are demonstrated with the analysis of a variety of intransigent difficult and complex samples. The net result is a more rapid production of data and perhaps, more importantly, the effective extraction of useful information from such data.
