Iodide sources in the aquatic environment and its fate during oxidative water treatment - A critical review
Iodine is a naturally-occurring halogen in natural waters generally present in concentrations between 0.5 and 100 mu g L-1. During oxidative drinking water treatment, iodine-containing disinfection by-products (I-DBPs) can be formed. The formation of I-DBP ...
PERGAMON-ELSEVIER SCIENCE LTD2022Hysteresis-Free Planar Perovskite Solar Module with 19.1% Efficiency by Interfacial Defects Passivation
Ulf Anders Hagfeldt, Bowen Yang, Jiajia Suo
In few years, perovskite solar devices have reached high efficiency on lab scale cells. Upscaling to module size, effective perovskite recipe and posttreatment are of paramount importance to the breakthrough of the technology. Herein this work, the develop ...
WILEY-V C H VERLAG GMBH2022Catalyzing Bond-Dissociation in Graphene via Alkali-Iodide Molecules
Klaus Kern, Stephan Rauschenbach, Sabine Abb, Sven Alexander Szilagyi, Hannah Julia Ochner
Atomic design of a 2D-material such as graphene can be substantially influenced by etching, deliberately induced in a transmission electron microscope. It is achieved primarily by overcoming the threshold energy for defect formation by controlling the kine ...
WILEY-V C H VERLAG GMBH2021Atomistic dynamics of elimination and nucleophilic substitution disentangled for the F- + CH3CH2Cl reaction
Chemical reaction dynamics are studied to monitor and understand the concerted motion of several atoms while they rearrange from reactants to products. When the number of atoms involved increases, the number of pathways, transition states and product chann ...
NATURE PORTFOLIO2021Structure and Reactivity of N-Heterocyclic Alkynyl Hypervalent Iodine Reagents
Rosario Scopelliti, Jérôme Waser, Farzaneh Fadaei Tirani, Matthew Wodrich, Eliott Hugo Joran Le Du
Ethynylbenziodoxol(on)e (EBX) cyclic hypervalent iodine reagents have become popular reagents for the alkynylation of radicals and nucleophiles, but only offer limited possibilities for further structure and reactivity fine-tuning. Herein, the synthesis of ...
2021Inhibition of Thiol‐Mediated Uptake with Irreversible Covalent Inhibitors
Jérôme Waser, Stefan Matile, Eliott Hugo Joran Le Du, Elija Grinhagena, Abhaya Kumar Mishra
Thiol-mediated uptake is emerging as method of choice to penetrate cells. This study focuses on irreversible covalent inhibitors of thiol-mediated uptake. High-content high-throughput screening of the so far largest collection of hypervalent iodine reagent ...
2021Quantifying Stabilized Phase Purity in Formamidinium-Based Multiple-Cation Hybrid Perovskites
Michael Graetzel, Shaik Mohammed Zakeeruddin, Thomas Paul Baumeler, Mohammad Ibrahim Dar, Neha Arora
A promising approach for the production of highly efficient and stable hybrid perovskite solar cells is employing mixed-ion materials. Remarkable performances have been reached by materials comprising a stabilized mixture of methylammonium (MA(+)) and form ...
2021Solid-state to solution helicity inversion of pseudotetrahedral chiral copper(II) complexes with 2,4-dihalo-salicylaldiminate ligands
The enantiopure Schiff bases (R or S)-N-1-( phenyl)ethyl-2,4-X-1,X2(-)salicylaldimine (X-1, X-2 = Cl, Br, I) coordinate to copper(II) and provide pseudotetrahedral bis[(S or R)-N-1-(phenyl)ethyl-(2,4-X-1,X-2-salicylaldiminato.2N,O)]-./.-Cu(II) (kappa N-2,O ...
ROYAL SOC CHEMISTRY2020Iodic acid, sulfuric acid and methanesulfonic acid collected during the Arctic Ocean 2018 expedition
Julia Schmale, Andrea Baccarini
Measurements of iodic acid, sulfuric acid and methanesulfonic acid concentration in the gas phase obtained with a nitrate chemical ionization mass spectrometer (we used an APi-TOF mass spectrometer produced by Tofwerk AG coupled with a Chemical ionization ...
2020Frequent new particle formation over the high Arctic pack ice by enhanced iodine emissions
Julia Schmale, Andrea Baccarini
In the central Arctic Ocean the formation of clouds and their properties are sensitive to the availability of cloud condensation nuclei (CCN). The vapors responsible for new particle formation (NPF), potentially leading to CCN, have remained unidentified s ...
