Strong Photocurrent Amplification in Perovskite Solar Cells with a Porous TiO2 Blocking Layer under Reverse Bias

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Mohammad Ibrahim Dar, Thomas Moehl, Yonghui Lee, Konrad Domanski, Leo-Philipp Heiniger, Jeong-Hyeok Im

We investigate two different types of TiO2 blocking layer (BL) deposition techniques commonly used in solid-state methylammonium lead triiodide perovskite (MaPbI(3))-based solar cells. Although these BLs lead to similar photovoltaic device performance, the ...

Reversible CO Binding Enables Tunable CO/H2 and CO/N2 Separations in Metal-Organic Frameworks with Exposed Divalent Metal Cations

Berend Smit, Wendy Lee Queen

Six metal-org. frameworks of the M2(dobdc) (M = Mg, Mn, Fe, Co, Ni, Zn; dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate) structure type bind carbon monoxide reversibly and at high capacity. IR spectra indicate that, upon coordination of CO to the divalent m ...

Adsorbed and near surface structure of ionic liquids at a solid interface

Kislon Voitchovsky, Juan José Segura Sugranes

The structure of solid-ionic liquid (IL) interfaces has been characterised with unprecedented clarity by employing a range of atomic force microscopy (AFM) imaging techniques and tip pressures appropriate for the system under study. Soft contact and amplit ...

RF-plasma pretreatment of surfaces leading to TiO2 coatings with improved optical absorption and OH-radical production

César Pulgarin, Juan Kiwi, Christophe Roussel, Sami Rtimi, Oualid Baghriche

Evidence is presented for the RF pretreatment of polyester enhances the TiO2 coating generation of oxidative species/radicals under a low level actinic light irradiation. After 30 min RF-plasma pretreatment of the polyester samples, the fastest bacterial i ...

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

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

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 ...

Structure of complex oxide nanoparticles in a Fe–14Cr–2W–0.3Ti–0.3Y2O3 ODS RAF steel

Nadine Baluc, Robin Schäublin

One of the most crucial steps in the development of oxide dispersion strengthened (ODS) reduced activation ferritic (RAF) steels is the engineering of their microstructure, which includes control of the type and size of oxide nanoparticles. In this work, t ...

Studies on the Effect of Strain on the Electronic Properties of Ultra Thin Films of Superconducting Cuprates

Nathaniel Wooding

High Tc superconductivity in cuprates is still an unresolved topic, and one particular challenge is why in-plane compressive strain enhances Tc in ultra thin LSCO-214 films (< 40nm), whilst tensile strain diminishes it. Especially intriguing is whether alt ...

Evaluation of silicate minerals for pH control during bioremediation: Application to chlorinated solvents

David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix

Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. This study evaluated a novel approach for buffering subsurface pH that relies on the use of silicate minerals as a long-term source of al ...

Al2O3 particle rounding in molten copper and Cu8wt%Al

Andreas Mortensen

We investigate processing-microstructure relationships in the production of Al2O3 particle reinforced copper composites by solidification processing. We show that during production of the composites by gas-pressure infiltration of packed Al2O3 particle pre ...
