Ag is a cost-effective alternative to Au as a catalyst for the electrochemical reduction of CO2 into CO, but a reduction in the accompanying overpotential is required to make Ag viable. In this study we use B to modulate the catalytic performance of

This study investigates carbon (C)-modified silver (Ag) thin film catalysts for electrochemical syngas production. The Ag-C catalyst is synthesized using a co-deposition process with separate C and Ag sputtering targets. It is found that co-depositio

The performance of the reference electrode is sometimes overlooked in the development of new electrochemical biosensors, which may result in a significant reduction in function even under standard operating conditions. This paper investigates the wor

The Svalbard Composite Tectono-Sedimentary Element (SCTSE) is located on the northwestern corner of the Barents Shelf and comprises a Carboniferous–Pleistocene sedimentary succession. Due to Cenozoic uplift, the succession is subaerially exposed in

Flood-generated hyperpycnal flows are dense, sediment-laden, turbulent flows that can form long-lived, bottom-hugging turbidity currents, which undoubtedly transport large volumes of fine-grained sediments into the ocean. However, their ability in tr

The competition between various carbohydrates in the binding to Concanavalin A (Con A) can be exploited in gravimetric microsensors that detect changes in mass or viscoelasticity as a function of glucose concentration. Such sensors are based on the i

Analysis of the sedimentary architecture of the early Billefjorden Trough, an exceptionally well-exposed Carboniferous half-graben located in Svalbard, Arctic Norway, allows detailed reconstruction of fault development and basin geometry. Sedimentary
