Probing structural and dynamic properties of MAPbCl3 hybrid perovskite using Mn2+ EPR

Hybrid methylammonium (MA) lead halide perovskites have emerged as materials exhibiting excellent photovoltaic performance related to their rich structural and dynamic properties. Here, we use multifrequency (X-, Q-, and W-band) electron paramagnetic reson ...

Photo-induced environmental remediation, biomedical imaging, and microbial inactivation by Mn-doped semiconductors: critical issues

Juan Kiwi, Sami Rtimi

The Mn-doping/decoration of S-containing semiconductor quantum dots (QDs) determine their photochemical properties and are important in the field of artificial photosynthesis. The Mn-mediated charge-transfer kinetics and energetics in composites of the typ ...

Stabilization of high-spin Mn ions in tetra-pyrrolic configuration on copper

Magalí Alejandra Lingenfelder

By means of Mn-Cu transmetalation, we incorporated Mn atoms in an array of TCNQ (7,7,8,8-tetracyanoquinodimethane) grown on Cu(100), forming a long range ordered and commensurate metal-organic coordination network (MOCN). Preliminary Sn alloying of the Cu( ...

UV and IR Spectroscopy of Transition Metal–Crown Ether Complexes in the Gas Phase: Mn2+(benzo-15-crown-5)(H2O)0–2

Thomas Rizzo, Yoshiya Inokuchi

Ultraviolet photodissociation (UVPD) and IR–UV double-resonance spectroscopy are performed for bare and microhydrated complexes of Mn2+(benzo-15-crown-5), Mn2+(B15C5)(H2O)n (n = 0–2), under cold (∼10 K) gas-phase conditions. Density functional theory (DFT) ...

Synthesis of Homogeneous Manganese-Doped Titanium Oxide Nanotubes from Titanate Precursors

László Forró, Arnaud Magrez, Kurt Schenk, Bálint Náfrádi, Endre Horvath, Zlatko Mickovic, Péter Szirmai, Rita Smajda, Dejan Dokic

We report a novel synthesis route of homogeneously manganese-doped TiO2 nanotubes in a broad concentration range. The scroll-type trititanate (H2Ti3O7) nanotubes prepared by hydrothermal synthesis were used as precursors. Mn2+ ions were introduced by an io ...

Stereoselectivity and electrostatics in charge-transfer Mn- and Cs-TCNQ(4) networks on Ag(100)

Klaus Kern, Sebastian Stepanow

Controlling supramolecular self-assembly is a fundamental step towards molecular nanofabrication, which involves a formidable reverse engineering problem. It is known that a variety of structures are efficiently obtained by assembling appropriate organic m ...

Formation of assimilable organic carbon during oxidation of natural waters with ozone, chlorine dioxide, chlorine, permanganate, and ferrate

Urs von Gunten

Five oxidants, ozone, chlorine dioxide, chlorine, permanganate, and ferrate were studied with regard to the formation of assimilable organic carbon (AOC) and oxalate in absence and presence of cyanobacteria in lake water matrices. Ozone and ferrate formed ...

Monolithic micro-direct methanol fuel cell in PDMS with microfluidic channel-integrated Nafion strip

Martinus Adela Maria Gijs, Meng Shen

We demonstrate a monolithic polymer electrolyte membrane fuel cell by integrating a narrow (200 mu m) Nafion strip in a molded polydimethylsiloxane (PDMS) structure. We propose two designs, based on two 200 mu m-wide and two 80 mu m-wide parallel microflui ...

Ionization and fragmentation of water clusters by fast highly charged ions

Ivano Tavernelli, Pablo Lopez Tarifa

We study the dissociative ionization of water clusters by impact of 12 MeV/u Ni25+ ions. Cold target recoil ion momentum spectroscopy (COLTRIMS) is used to obtain information about stability, energetics and charge mobility of the ionized water clusters. An ...
