One contributory factor to the “warming hiatus” is an increase in volcanically induced cooling over the early 21st century. Here a research team identifies the signals of late 20th and early 21st century volcanic activity in multiple observed climate variables.
Pulsed electron sources with high instantaneous current have successfully shortened exposure times (thus increasing the temporal resolution) by about six orders of magnitude over conventional sources while providing the necessary signal-to-noise ratio for dynamic imaging.
The research team demonstrates that the energy storage capacity of graphene macro-assemblies can be increased nearly 3-fold (up to 23 W h kg−1) by facile, non-covalent surface modification with anthraquinone (AQ).
A low‐cost, high‐throughput, lift‐off‐free nanolithographic method is developed for creating hexagonal arrays of sub‐30‐nm‐sized pores on a metal film, achieving uniform coverage over an entire wafer of 10 cm in diameter.
Three‐dimensional printing of viscoelastic inks to create porous, elastomeric architectures with mechanical properties governed by the ordered arrangement of their sub‐millimeter struts is reported.
The synthesis of ultralow‐density (>5 mg/cm3) bulk materials with interconnected nanotubular morphology and deterministic, fully tunable feature size, composition, and density is presented.
We describe ramp-compression measurements for diamond, achieving 3.7-fold compression at a peak pressure of 5 terapascals (equivalent to 50 million atmospheres).
The present work describes continuum modeling of selective laser melting as envisioned for eventual support of part-scale modeling of this fabrication process to determine end-state information such as residual stresses and distortion.
The electronic transport in centimeter‐sized three‐dimensional bulk nanographene monoliths can be dynamically controlled via electrochemically induced surface charge density.
The kinetics of carbonate exchange on the [NpO2(CO3)3]4− complex, shown here in ball-and-stick form, were measured as a function of solution pH.
