Modeling regional air quality and climate: Improving organic aerosol and aerosol activation processes in WRF/Chem version 3.7.1

Yi Zhang, Athanasios Nenes

Air quality and climate influence each other through the uncertain processes of aerosol formation and cloud droplet activation. In this study, both processes are improved in the Weather, Research and Forecasting model with Chemistry (WRF/Chem) version 3.7. ...

Nitrate formation during ozonation as a surrogate parameter for abatement of micropollutants and the N-nitrosodimethylamine (NDMA) formation potential

Urs von Gunten, Florian Frédéric Vincent Breider, Jun Ma, Yang Song

In this study, nitrate formation from ammonium and/or dissolved organic nitrogen (DON) was investigated as a novel surrogate parameter to evaluate the abatement of micropollutants during ozonation of synthetic waters containing natural organic matter (NOM) ...

Isomer-Pure Bis-PCBM-Assisted Crystal Engineering of Perovskite Solar Cells Showing Excellent Efficiency and Stability

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jingshan Luo, Chenyi Yi, Dongqin Bi, Norman Pellet, Xiong Li, Fei Zhang, Shilong Wang

A fullerene derivative (alpha-bis-PCBM) is purified from an as-produced bis-phenyl-C-61-butyric acid methyl ester (bis-[60]PCBM) isomer mixture by preparative peak-recycling, high-performance liquid chromatography, and is employed as a templating agent for ...

Inactivation of enteric viruses by ozone

Urs von Gunten, Tamar Kohn, Camille Wolf

In Switzerland, newly introduced regulation mandates the upgrade of major wastewater treatment plants (WWTP) with an advanced treatment step such as ozonation. This offers a unique opportunity to study the inactivation of enteric virus during ozonation of ...

New Horizons for Perovskite Solar Cells Employing DNA-CTMA as the Hole-Transporting Material

Mohammad Khaja Nazeeruddin

• Invited for this month's cover are the groups at Ecole Polytechnique Federale de Lausanne and Kyung Hee University, who successfully applied DNA as the hole-transporting layer in a perovskite solar cell. The Full Paper itself is available at 10.1002/cssc ...

Perovskite Solar Cells Employing Molecularly Engineered Zn(II) Phthalocyanines as Hole-transporting Materials

Mohammad Khaja Nazeeruddin, Kyung Taek Cho, Kasparas Rakstys

Amino donor groups-substituted zinc(II) phthalocyanines (ZnPcs) BI25, BL07 and BL08 were obtained via cyclotetramerization of suitable phthalonitriles that were synthesized by Pd catalyzed amination reaction between 4-iodophthalonitrile and a selected seco ...

Transformation of Contaminant Candidate List (CCL3) compounds during ozonation and advanced oxidation processes in drinking water: Assessment of biological effects

Urs von Gunten, Kristin Schirmer, Silvio Canonica

The removal of emerging contaminants during water treatment is a current issue and various technologies are being explored. These include UV- and ozone-based advanced oxidation processes (AOPs). In this study, AOPs were explored for their degradation capab ...

Bromide Sources and Loads in Swiss Surface Waters and Their Relevance for Bromate Formation during Wastewater Ozonation

Urs von Gunten

Bromide measurements and mass balances in the catchments of major Swiss rivers revealed that chemical industry and municipal waste incinerators are the most important bromide sources and account for similar to 50% and similar to 20%, respectively, of the s ...

Not All That Glitters Is Gold: Metal-Migration-Induced Degradation in Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski

Perovskite solar cells (PSCs) have now achieved efficiencies in excess of 22%, but very little is known about their long-term stability under thermal stress. So far, stability reports have hinted at the importance of substituting the organic components, bu ...
