Enhanced photon harvesting in silicon multicrystalline solar cells by new lanthanide complexes as light concentrators
(2011)Four europium complexes with enhanced luminescent properties have been synthesized. Thin transparent films of the complexes were prepared on glass panes and then were examined as efficient luminescent solar concentrators ...

Exploring the origin of high optical absorption in conjugated polymers
(2016)The specific optical absorption of an organic semiconductor is critical to the performance of organic optoelectronic devices. For example, higher light-harvesting efficiency can lead to higher photocurrent in solar cells ...

Fourier transform infrared (FTIR) and step-scan time-resolved FTIR spectroscopies reveal a unique active site in cytochrome caa3 oxidase from Thermus thermophilus
(2002)Fourier transform infrared (FTIR) and step-scan time-resolved FTIR difference spectra are reported for the [carbonmonoxy]cytochrome caa3 from Thermus thermophilus. A major C-O mode of heme a3 at 1958 cm-1 and two minor ...

Nanoscopic cationic methacrylate star homopolymers: Synthesis by group transfer polymerization, characterization and evaluation as transfection reagents
(2004)Seven star polymers with degrees of polymerization (DPs) of the arms from 10 to 100 and dimensions in the nanometer range were prepared using sequential group transfer polymerization of 2-(dimethylamino)-ethyl methacrylate ...

Pulse collisions and polarisation conversion for optical fibres
(1994)Axisymmetric fibres support linearly and circularly polarised sech pulses and also elliptically polarised pulses having more complicated profile. Collisions between any two such pulses are studied numerically. Large collision ...

Raman spectroscopy using a fiber optic probe with subwavelength aperture
(1994)Raman spectroscopy with subwavelength spatial resolution of a diamond sample was recorded using a tapered fiber optical probe in conjunction with a conventional Raman spectrometer. The experiment demonstrates the potential ...

Ultraviolet Absorbance and Circular Dichroism of Pf1 Virus: Nucleotide/Subunit Ratio of Unity, Hyperchromic Tyrosines and DNA Bases, and High Helicity in the Subunits
(1994)Data have been obtained for the Pfl virion that establish its stoichiometry and conformational features of its DNA and its protein. The absorbance spectrum of the dissociated virus under alkaline denaturing conditions is ...
