Greenhouse gas emissions in New Zealand: a preliminary consumption-based analysis [PDF]

open access: yes, 2014
: New Zealand’s per capita greenhouse gas emissions are usually calculated by taking total emissions as reported under the Kyoto Protocol or the United Nations Framework Convention on Climate Change and simply dividing by population. However this focuses

W‐N‐C Tandem Catalytic Centers Mediating Efficient Charge Transfer for the Enhanced Radical‐Path U(VI) Photoreduction

open access: yesAdvanced Science, EarlyView.
This work constructed a tandem W−N−C center to simultaneously achieve the regulation of reaction pathways and optimization of charge separation efficiency. The Lewis‐acidic W6+ sites activated O2 to generate O2−$O_2^ - $, with enhanced charge separation via electronic modulation, steering U(VI) reduction down an efficient radical pathway.

Enhancing Biogenic Formic Acid Production in the Modified OxFA Process by Acetonitrile Addition

open access: yesAdvanced Science, EarlyView.
In this study, the beneficial effect of using acetonitrile as a co‐solvent in the modified OxFA process is shown, outperforming methanol, demonstrating improved reaction kinetics combined with high selectivity for the HPA‐2 (H5PV2Mo10O40) catalyzed oxidation of xylose to FA.

Photocatalytic Synthesis of Pentafluorosulfanyl Ketones, Acetals, and BCP Motifs Utilizing SF6

open access: yesAdvanced Science, EarlyView.
A photocatalytic single electron reduction strategy is reported for the activation and valorization of sulfur hexafluoride (SF6), a potent greenhouse gas. Under mild conditions, SF6 is reduced to generate pentafluorosulfanyl (SF5) radicals, enabling direct access to pentafluorosulfanyl ketones, acetals, and BCP motifs.
