Photosynthesis of NH3 from NO3– using CH4 in Homogenous Rhenium Catalysis
Angewandte Chemie International Edition, Accepted Article.We present Re catalysis of one‐pot synthesis of NH3 from NO3– using CH4 as a reductant under UV light irradiation at room temperature and normal pressure. NO3– leads to environmental issues such as water contamination, eutrophication and biodiversity loss.

Networks of digital humanities scholars: The informational and social uses and gratifications of Twitter [PDF]
, 2015 Big data research is currently split on whether and to what extent Twitter can be characterised as an informational or social network. We contribute to this line of inquiry through an investigation of digital humanities scholars' uses and gratifications of Twitter.

Photochemical Conversion of Indazoles into Benzimidazoles
Angewandte Chemie International Edition, Accepted Article.Fragment‐based drug discovery relies on preparing diverse libraries of advanced building blocks, often incorporating heteroaromatic motifs. Altering the core of heteroaromatics to maximise library diversity typically requires de novo synthesis of each system. This can be often challenging when specific substitution patterns are needed.

Probabilistic Inference of Twitter Users' Age based on What They Follow [PDF]
arXiv, 2016 Twitter provides an open and rich source of data for studying human behaviour at scale and is widely used in social and network sciences. However, a major criticism of Twitter data is that demographic information is largely absent. Enhancing Twitter data with user ages would advance our ability to study social network structures, information flows and ...

Angewandte Chemie International Edition, Accepted Article.Isotope labelling, particularly with deuterium (2H), plays a critical role in drug discovery due to its ease of incorporation and its potential to switch unwanted metabolic transformations. Deuterium incorporation can enhance drug stability, affect pharmacokinetics, and alter metabolism pathways.

Angewandte Chemie International Edition, Accepted Article.Photoredox catalytic systems are widely used in free radical polymerization as an important photoinitiating approach. However, many reported photoredox catalytic systems are limited by their low stabilities, high excitation powers, and low initiating efficiencies upon excitation in the visible region. Therefore, it is still a great challenge to develop

Scholars on Twitter: who and how many are they? [PDF]
arXiv, 2017 In this paper we present a novel methodology for identifying scholars with a Twitter account. By combining bibliometric data from Web of Science and Twitter users identified by Altmetric.com we have obtained the largest set of individual scholars matched with Twitter users made so far.
