BRILLQUIN A N D RAYLHGH SCATTERING INVESTIGATION OF SOLID He4 BY STIMULATED BRILLOUIN SCATTERING
Solid helium is generally referred to as a quantum crystal because its zero point energy is cornpaFable to the binding energy. Consequently one expects its behaviour to 6e quite different from ordinary cIassical solids. The amplitude of the zero point motion, which is nearly 30 per cent of the interatomic distance, should cause anharmonicities in the latti& potential to play an important role '...
متن کاملTarget-assembled exciplexes based on Scorpion oligonucleotides.
Scorpion probes, specific DNA probe sequences maintained in a hairpin-loop, can be modified to carry the components of an exciplex for use as a novel fluorescence-based method for specific detection of DNA. The exciplex partners (5'-pyrenyl and 3'-naphthalenyl) were attached to oligonucleotides via phosphoramidate links to terminal phosphate groups. Hybridization of the probe to a complementary...
متن کاملTriplet exciplexes as energy transfer photosensitisers.
Experimental evidence is provided for the occurrence of triplet-triplet energy transfer from benzoylthiophene-indole exciplexes to naphthalenes with a remarkable stereodifferentiation; chiral recognition is also observed in the decay of the generated naphthalene triplets.
متن کاملExcited state kinetics of anthracene-bridge-aniline intramolecular exciplexes.
We report on the synthesis and characterization of fluorescent halogen substituted anthracene-bridge-aniline (ABA) supermolecules that undergo structural reorganization on photoexcitation to form transient complexes. The syntheses were achieved in high yields on a large scale and the molecular structures were confirmed by single crystal X-ray diffraction. The photophysics of the ABA supermolecu...
متن کاملHE4 tissue expression and serum HE4 levels in healthy individuals and patients with benign or malignant tumors: a systematic review.
Human epididymis protein 4 (HE4) has received major attention as a potential tumor marker in epithelial ovarian cancer; however, evidence of significant overexpression of HE4 in several other human cancers is expanding. To assess the possible limitations or benefits of HE4 in a clinical setting, this review aims to systematically outline published results of HE4 tissue expression and serum HE4 ...
