The "electrochemical/chemical method" (or "E/C method") is a new wet chemical method for synthesizing semiconductor quantum dots on graphite surfaces. The E/C synthesis of quantum dots composed of the generic semiconducting salt, MX, typically involves three steps: (1) electrochemical deposition of nanoparticles of the metal, M degrees, from a solution of metal ions, M(n)(+); (2) electrochemica...

NELLA LIQUIDITÀ DELL'INFOSFERA, A BEN GUARDARE, SI POSSONO SCORGERE ARCIPELAGHI DI ATOLLI FATTI DI INTERESSI INTERDISCIPLINARI, DI CAPACITÀ DI STUPIRSI DI FRONTE AD OGNI PICCOLO DETTAGLIO DELLA NATURA, DI SETE INSAZIABILE PER IL SAPERE, DI INTERESSE PER L'ASTRAZIONE E PER L'ESPERIMENTO, DI PIACERE PER LA CREAZIONE, DI INGEGNOSITÀ TECNOLOGICA, DI SPINTA PROPULSIVA ALLA PRODUZIONE INNOVATIVA, DI ...

A combination of experimental and density functional theory (DFT) investigations suggests that the Cu-catalyzed fluorination of unsymmetrical diaryliodonium salts with general structure [Mes(Ar)I]+ in N,N'-dimethylformamide proceeds through a CuI/CuIII catalytic cycle. A low concentration of fluoride relative to combined iodonium reagent plus copper ensures that [Mes(Ar)I]+ is available as the ...

A novel class of derivatized acetylacetonate (acac) linkers for robust functionalization of TiO2 nanoparticles (NPs) under aqueous and oxidative conditions is reported. The resulting surface adsorbate anchors are particularly relevant to engineering photocatalytic and photovoltaic devices since they can be applied to attach a broad range of photosensitizers and photocatalytic complexes and are ...

INTRODUCTION This study compared canal and isthmus debridement efficacies between side-vented needle irrigation (SNI) and continuous ultrasonic irrigation (CUI) in the mesial root of mandibular first molars with narrow isthmuses using a closed-canal design. METHODS Micro-computed tomography scanning was used to select 20 teeth, each containing a narrow isthmus. Each root was sealed at the ape...

In a recent letter, Cui, Duan and Chan propose a generalisation of the Scott-Barreto method to build a larger family of MNT curves, and they claim that their proposal is also applicable to other curve construction methods. Here we show that the Cui-Duan-Chan technique is irrecoverably flawed.
