Journal ArticleDOI
Enhanced resolution beyond the Abbe diffraction limit with wavelength-scale solid immersion lenses
TL;DR: From full three-dimensional, finite-difference time-domain calculations, it is demonstrated that the FWHM of the focal spot of an objective-lens-nSIL system can be reduced by greater than 25% compared to a regular macroscopic SIL.
Journal ArticleDOI
Characterization of weak NH-π intermolecular interactions of ammonia with various substituted π-systems
TL;DR: The present study details the results obtained on gas-phase complexes of ammonia with various substituted pi systems using both laser vibrational spectroscopy and ab initio calculations, finding that polarizabilities of the pi-electron systems play a very important role in governing the nature and geometry of the NH-pi interaction.
Journal ArticleDOI
Radioactive iodine capture and storage from water using magnetite nanoparticles encapsulated in polypyrrole
TL;DR: This excellent iodine capture and storage from iodine contaminated water is an environment friendly, inexpensive and large scale method.
Journal ArticleDOI
Hydrogen‐Release Mechanisms in Lithium Amidoboranes
TL;DR: Light is shed on the mechanisms involved in the loss of one molar equivalent of H(2) from solid lithium amidoboranes by using high-level ab initio calculations of monomeric and dimeric compounds in the gas phase for the design of future hydrogen-storage media.
Journal ArticleDOI

TL;DR: Quinoxaline derivatives (1-4) bearing two imidazolium moieties are found to strongly bind anions and show unique charge-transfer fluorescent responses to pyrophosphate and acetate, whereas they show excimer formation with other anions.
