Operando diffuse reflectance infrared detection of cyanide intermediate species during the reaction of formaldehyde with ammonia over V2O(5)/ WO3-TiO2

Davide Ferri, Oliver Kröcher, Rob Jeremiah G. Nuguid

Hydrogen cyanide (HCN) is a highly poisonous gas that can form through the reaction between formaldehyde and ammonia (NH3) in the exhaust. While this detrimental side reaction has been the subject of recent catalytic studies under selective catalytic reduc ...

Photoredox-Catalyzed Decarboxylation for the Transfer of Alkynes and Nitriles Using Hypervalent Iodine Reagents

Franck Le Vaillant

Aliphatic alkynes and nitriles are privileged motifs in organic chemistry. Therefore, alkynes and nitriles have played a central role for the exploration and development of novel strategies to forge C-C bonds in efficient manner. They are broadly used as v ...

Engineering of highly efficient tetrahydroquinoline sensitizers for dye-sensitized solar cells

Ulf Anders Hagfeldt, Yan Hao

Four novel tetrahydroquinoline dyes by inserting isophorone and/or thiophene moieties as π bridge between the electron donating unit of substituted tetrahydroquinoline and the electron withdrawing unit of cyano carboxylic acid have been synthesized and suc ...

Influence of the Anchoring Modes on the Electronic and Photovoltaic Properties of D−π–A Dyes

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Robin Humphry-Baker, Magdalena Anna Marszalek, Takeru Bessho, Mateusz Barnaba Wielopolski

Five new donor−π-bridge−acceptor (D−π−A) organic sensitizers with cyano and/or triple bond substituted benzoic acid as acceptor/anchoring groups were synthesized and tested for their performance in dye-sensitized solar cells (DSCs). The systematic incorpor ...

Design of Dye Acceptors for Photovoltaics from First-Principles Calculations

Michael Graetzel, Mohammad Khaja Nazeeruddin, Efthimios Kaxiras, Sheng Meng

We investigate a set of donor-pi-acceptor (D-pi-A) dyes with new acceptor groups for dye-sensitized solar cells, using time-dependent density-functional-theory calculations of the electronic structure and optical absorption. We considered three types of mo ...

New electrolytes for high power Li-ion batteries

Davide Di Censo

A new generation of high power Li-ion batteries that avoid carbon as anodic material replacing it with the spinel Li4Ti5O12 has been studied in this work. For these new Li-ion cells new electrolyte compositions can be considered. The main work of this thes ...

The complex between hydrogenase-maturation proteins HypC and HypD is an intermediate in the supply of cyanide to the active site iron of [NiFe]-hydrogenases

Melanie Blokesch

Carbamoylphosphate has been shown to be the educt for the synthesis of the CN ligands of the NiFe metal centre of hydrogenases from Escherichia coli. In the absence of carbamoylphosphate, cells accumulate a complex of two hydrogenase maturation proteins, n ...
