Journal ArticleDOI
Palladium-catalyzed C-H homocoupling of bromothiophene derivatives and synthetic application to well-defined oligothiophenes.
Masabumi Takahashi,Kentaro Masui,Hiroki Sekiguchi,Nobuhiko Kobayashi,Atsunori Mori,Masahiro Funahashi,Nobuyuki Tamaoki +6 more
TL;DR: Tolerance of the carbon-bromine bond to the palladium-catalyzed C-H homocoupling results in oligothiophenes bearing C-Br bonds at the terminal thiophene rings, which allow further transformation by the catalysis of a transition-metal complex.
Journal ArticleDOI
Conduction channels at finite bias in single-atom gold contacts
TL;DR: In this paper, the effect of a finite voltage bias on the conductance of single-atom gold contacts was investigated using the nonequilibrium-Green-function formalism, and the voltage drop through the contacts and the main drop was found near the negative electrode.
Journal ArticleDOI
Magnetism-mediated thermoelectric performance of the Cr-doped bismuth telluride tetradymite
Jean-Baptiste Vaney,S. Aminorroaya Yamini,S. Aminorroaya Yamini,Hirokazu Takaki,Kazuaki Kobayashi,Nobuhiko Kobayashi,Takao Mori,Takao Mori +7 more
TL;DR: In this article, an improved quality criterion of bismuth telluride upon chromium substitution was reported, which indicated that taking advantage of such relatively easily implemented magnetic doping effects along with existing strategies can lead to enhanced efficiency of thermoelectric materials.
Journal ArticleDOI
Conductance quantization and magnetoresistance in magnetic point contacts.
TL;DR: The magnetoresistance is strongly enhanced for the narrow PC and oscillates with the conductance and the sequence of quantized conductances depends on the relative orientation of magnetizations between left and right electrodes.
Journal ArticleDOI
First-principles study of electron transport through monatomic Al and Na wires
TL;DR: In this article, the conduction channels of monatomic Al and Na atom wires bridged between metallic jellium electrodes were investigated using the first-principles recursion-transfer matrix method.
