Decarbonizing the fertilizers sector: an alternative pathway for urea and nitric acid production

François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos

In order to alleviate the environmental impact that nitrogen fertilizers production is responsible for, several efforts have been addressed to incentivize the partial or total decarbonization of the supply chains of ammonia and its derivatives. The decarbo ...

Data-Driven Discovery of Organic Electronic Materials Enabled by Hybrid Top-Down/Bottom-Up Design

Rubén Laplaza Solanas, Sergio Vela Llausi, Jacob Terence Blaskovits

The high-throughput exploration and screening of molecules for organic electronics involves either a 'top-down' curation and mining of existing repositories, or a 'bottom-up' assembly of user-defined fragments based on known synthetic templates. Both are t ...

Aerosol microphysics and chemical composition in the central Arctic atmosphere during the MOSAiC expedition

Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Nora Bergner, Hélène Paule Angot, Lubna Dada

The Arctic environment is transforming rapidly due to climate change. Aerosols’ abundance and physicochemical characteristics play a crucial, yet uncertain, role in these changes due to their influence on the surface energy budget, and aerosol properties a ...

High-Throughput Sizing, Counting, and Elemental Analysis of Anisotropic Multimetallic Nanoparticles with Single-Particle Inductively Coupled Plasma Mass Spectrometry

Andreas Züttel, Natalia Gasilova, Cedric David Koolen, Wen Luo, Mo Li, Ayush Agarwal

Nanoparticles (NPs) have wide applications in physical and chemical processes, and their individual properties (e.g., shape, size, and composition) and ensemble properties (e.g., distribution and homogeneity) can significantly affect the performance. Howev ...

Chemical evolution of primary and secondary biomass burning aerosols during daytime and nighttime

Athanasios Nenes, Satoshi Takahama, Spyros Pandis, Amir Yazdani

Fine particulate matter (PM) affects visibility, climate, and public health. Biomass burning (BB) in the forms of residential wood burning, wildfires, and prescribed burning is a major source of primary and secondary organic matter (OM, an important fracti ...

Annual aerosol chemical composition retrieved from an aerosol mass spectrometer in the central Arctic

Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Hélène Paule Angot, Lubna Dada

The Arctic environment is transforming rapidly due to climate change, which induces several feedback processes such as retreating sea ice, changing atmospheric transport patterns and cloud formation. In addition, more local pollution due to shipping and re ...

Impact of ZnO on C3S hydration and C-S-H morphology at early ages

Karen Scrivener, Xuerun Li

The hydration of ZnO doped C3S was investigated. Characteristics of the hydrated pastes including mechanical strength, degree of hydration, microstructure, pore structure, bound water and the chemical composition of C-S H are reported. 0.26 and 0.90 wt% of ...

An in-situ 3D micro-XRD investigation of water uptake by alkali-silica-reaction (ASR) product

Mahdieh Shakoorioskooie

The ASR products in concrete have various chemical compositions. It is yet unclear whether and how these products develop micro-expansion upon moisture ingress. This paper presents a 3D in-situ observation of the crystallography and volume change of an ASR ...
