Continental shelves and shelf seas play a central role in the global carbon cycle. However, their importance with respect to trace element and isotope (TEI) inputs to ocean basins is less well understood. Here, we present major findings on shelf TEI biogeochemistry from the GEOTRACES programme as well as a proof of concept for a new method to estimate shelf TEI fluxes. The case studies focus on advances in our understanding of TEI cycling in the Arctic, transformations within a major river estuary (Amazon), shelf sediment micronutrient fluxes and basin-scale estimates of submarine groundwater discharge...

The major risk factor for ovarian cancer (OC) is mutation of the BRCA1 or BRCA2 DNA mismatch repair genes, which occurs in approximately 10% of OC cases. Most previous studies have demonstrated that BRCA1- and BRCA2-mutated OCs are associated with better prognosis than sporadic OCs. However, information about the patterns and clinical course of the metastatic spread of BRCA-mutated OCs is limited. Herein, we describe a case of OC with a BRCA1 mutation and skin metastases in a 49-year-old patient, which to the best of our knowledge has not been reported previously...

Molybdenum disulfide with atomic-scale flatness has application potential in high speed and low power logic devices, owing to its scalability and intrinsic high-mobility. However, to realize viable technologies based on two-dimensional materials, techniques that enable their large-area growth with high quality and uniformity on wafer-scale is a pre-requisite. Here, we provide a route toward highly uniform growth of a wafer-scale, four-layered MoS2 film on a 2-inch substrate via a sequential process consisting of the deposition of a molybdenum trioxide precursor film by sputtering followed by post-sulfurization using a chemical vapor deposition process...

We demonstrate here that several different graphene nanoribbon (GNR) samples can be separated from the GNR mixture synthesized by conventional methods. The sheet resistance of the purified GNR gradually decreased with decreasing pressure at 30 °C, whereas it increased at 100 °C. A hypothesis based on van der Waals attractive interactions between GNR sheets was introduced to explain this finding. This hypothesis verified by the shifted main peaks in vacuum X-ray diffraction spectra: 0.022 nm and 0.041 nm shifts were observed for reduced graphene oxide (RGO) and GNR, respectively...
