Journal ArticleDOI
Hydrolysis of DNA and RNA by lanthanide ions: mechanistic studies leading to new applications
TL;DR: The following conclusions have been obtained on the basis of various kinetic and spectroscopic evidence: for the hydrolysis of both DNA and RNA, the catalytically active species are dinuclear hydroxo-clusters, and CeIV enormously activates DNA and promotes the formation of the pentacoordinated intermediate.
Journal ArticleDOI
Real-space imaging of transient carrier dynamics by nanoscale pump–probe microscopy
TL;DR: By combining advanced ultrashort-pulse laser technology with scanning tunneling microscopy, the authors demonstrate that they can directly image transient carrier dynamics in nanostructures in real space.
Journal ArticleDOI
Phase switching of a single isomeric molecule and associated characteristic rectification.
TL;DR: The novel phase switching of a photoactive isomeric molecule, N-(2-mercaptoethyl)-4-phenylazobenzamide (Azo molecule) at a single-molecule level is observed, for the first time, which exhibits a distinctive change in the conductive characteristic under scanning tunneling microscope (STM) measurement.
Journal ArticleDOI
The Molecular Abacus: STM Manipulation of Cyclodextrin Necklace
TL;DR: In this article, the authors proposed a molecular counting-device based on the molecular necklace of cyclodextrin (CyD), which can store molecular information in terms of shuttle position.
Journal ArticleDOI

TL;DR: In this article, a carrier-envelope-phase-controlled single-cycle terahertz electric fields can coherently drive electron tunnelling either from a nanotip to a sample or vice versa.
