Can the Modular Helium Reactor Compete in the Hydrogen Economy [PDF]

open access: yes
In today’s energy economy, hydrogen is primarily used in the petroleum refining and petrochemical industries. The dominant technology for generating hydrogen is Steam Methane Reforming (SMR), which uses natural gas as both feedstock and fuel. In the much-

Isotopic evidence for biogenic molecular hydrogen production in the Atlantic Ocean [PDF]

open access: yes, 2015
Oceans are a net source of molecular hydrogen (H2) to the atmosphere. The production of marine H2 is assumed to be mainly biological by N2 fixation, but photochemical pathways are also discussed.

Tailoring the Properties of Functional Materials With N‐Oxides

open access: yesAdvanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.
