Size-dependent thermochromism through enhanced electron-phonon coupling in 1 nm quantum dots.

Angewandte Chemie (International ed. in English)

Tamaki H, Watanabe H, Kamiyama S, Oaki Y, Imai H.
PMID: 25132195
Angew Chem Int Ed Engl. 2014 Sep 26;53(40):10706-9. doi: 10.1002/anie.201406330. Epub 2014 Aug 11.

1 nm CuO quantum dots (QDs) were produced in size-controlled super-micropores of a silica matrix. The reversible color change of the QDs from pale blue to deep green was clearly observed in a wide temperature range from 298 to...

PMID: 27286370
Biosci Biotechnol Biochem. 1992 Jan;56(7):1007-11. doi: 10.1271/bbb.56.1007.

The effects of okadaic acid, an inhibitor of protein phosphatases types 1 and 2A, from the sponge Halichondria okadai Kadota, on the embryonic development of the starfish Asterina pectinifera, were investigated. When cultured in okadaic acid from fertilization, the...

DIFFERENCES IN THE PRODUCTION AND EXCRETION KINETICS OF OKADAIC ACID, DINOPHYSISTOXIN-1, AND PECTENOTOXIN-2 BETWEEN CULTURES OF DINOPHYSIS ACUMINATA AND DINOPHYSIS FORTII ISOLATED FROM WESTERN JAPAN(1).

Surg Neurol Int. 2015 Jun 01;6:95. doi: 10.4103/2152-7806.157949. eCollection 2015.

BACKGROUND: The superficial temporal artery (STA) to proximal posterior cerebral artery (PCA) (P2 segment) bypass is one of the most difficult procedures to perform because the proximal PCA is located deep and high within the ambient cistern. STA to...

Evidence for an amphibian sixth digit.

INTRODUCTION: Despite the great diversity in digit morphology reflecting the adaptation of tetrapods to their lifestyle, the number of digits in extant tetrapod species is conservatively stabilized at five or less, which is known as the pentadactyl constraint.RESULTS: We...

Plasmon resonance-enhanced circularly polarized luminescence of self-assembled meso-tetrakis(4-sulfonatophenyl)porphyrin-surfactant complexes in interaction with Ag nanoparticles.

Chemical communications (Cambridge, England)

Harada T, Kajiyama N, Ishizaka K, Toyofuku R, Izumi K, Umemura K, Imai Y, Taniguchi N, Mishima K.
PMID: 25111425
Chem Commun (Camb). 2014 Oct 04;50(76):11169-72. doi: 10.1039/c4cc04477k.

The chiroptical properties of an anionic meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS) complexed with cationic surfactants were enhanced by interaction with silver nanoparticles (AgNPs) in acidic solution. Improvement in chiroptical properties was revealed by circular dichroism (CD) and circularly polarized luminescence (CPL), with...
