To determine the thermal noise limit of graphene biotransistors, we have measured the complex impedance between the basal plane of single-layer graphene and an aqueous electrolyte. The impedance is dominated by an imaginary component but has a finite real component. Invoking the fluctuation–dissipation theorem, we determine the power spectral density...

Gas hydrates, pervasive in continental margin sediments, are expected to release methane in
response to ocean warming, but the geographic range of dissociation and subsequent flux of methane to
the ocean are not well constrained. Sediment column thermal models based on observed water column
warming trends offshore Washington (USA) show...

Winter climate is expected to change under future climate scenarios, yet the majority of winter ecology research is focused in cold-climate ecosystems. In many temperate systems, it is unclear how winter climate relates to biotic responses during the growing season. The objective of this study was to examine how winter...

Combined plasmonic nanocrystals and metal–organic framework
thin-films are fabricated for sensing gases in the near-infrared
range. This nanocomposite thin-film shows a highly sensitive response
in near-infrared absorption, which is attributed to preconcentration
of gas molecules in metal–organic framework pores causing close
proximity to the electromagnetic fields at the plasmonic nanocrystal...

The heterogeneous reactions of benzo[a]pyrene-d₁₂ (BaP-d₁₂), benzo[k]fluoranthene-d₁₂ (BkF-d₁₂), benzo[ghi]perylene-d₁₂ (BghiP-d₁₂), dibenzo[a,i]pyrene-d₁₄ (DaiP-d₁₄), and dibenzo[a,l]pyrene (DalP) with NO₂, NO₃/N₂O₅, and OH radicals were investigated at room temperature and atmospheric pressure in an indoor Teflon chamber and novel mono NO₂-DaiP, and mono NO₂-DalP products were identified. Quartz fiber filters (QFF) were used...

Litter decomposition is a keystone ecosystem process impacting nutrient cycling and productivity, soil properties, and the terrestrial carbon (C) balance, but the factors regulating decomposition rate are still poorly understood. Traditional models assume that the rate is controlled by litter quality, relying on parameters such as lignin content as predictors....

Microbial communities mediate the biogeochemical cycles that drive ecosystems, and it is important to understand how these communities are affected by changing environmental conditions, especially in complex coastal zones. As fresh and marine waters mix in estuaries and river plumes, the salinity, temperature, and nutrient gradients that are generated strongly...

Eucalypts are the world’s most widely planted hardwood trees. Their outstanding diversity, adaptability and growth have
made them a global renewable resource of fibre and energy. We sequenced and assembled >94% of the 640-megabase
genome of Eucalyptus grandis. Of 36,376 predicted protein-coding genes, 34% occur in tandem duplications, the largest...

The stereospecific reagent-controlled homologation (StReCH) of boronic esters with putative lithiooxiranes generated in situ from appropriate precursors via sulfoxide-lithium exchange, tin-lithium exchange, and direct lithiation is described with an emphasis on the first lithiation technique which allows for the regio- and stereo-specific generation of all types of lithiooxirane isomer. Transient...

Estimates of the relative motion between the Hawaiian and Louisville hot spots have consequences
for understanding the role and character of deep Pacific-mantle return flow. The relative motion between
these primary hot spots can be inferred by comparing the age records for their seamount trails. We report
⁴⁰Ar/³⁹Ar ages for...
