Solar-Terrestrial PhysicsPrecision neutron monitors providing continuous monitoring with a statistical accuracy of ~0.15 %/hr are effective for studying cosmic ray variations; therefore, contributions from other error sources should not exceed the contribution of this ...

Advanced Science, EarlyView.A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior

Advanced Science, EarlyView.We demonstrate that the inverse relationship between viscosity and conductivity in structured electrolytes can be circumvented by leveraging their hydrogen bonding networks for Grotthuss proton transport. Using a mixture of imidazole and levulinic acid, we show that the existence of extended hydrogen‐bonded chains that can rapidly reorient result in ...

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Advanced Science, EarlyView.An orally administered, drug‐free hyaluronic acid nanoassembly, uhNAs‐OA, accumulates in the inflamed colon and is preferentially internalized by M1‐like macrophages via HA‐CD44 interactions. uhNAs‐OA scavenges excess ROS, suppresses NF‐κB signaling and remodels the colonic immune landscape, resulting in robust therapeutic efficacy in acute, chronic ...

Advanced Science, EarlyView.Green mechanochemical copolymerization was developed for universal interfacial modification of Group 13 and related fillers. By leveraging Lewis acid–base coordination to anchor sulfur‐containing polymers—validated via multiscale characterization and DFT—this versatile method boosts performance across liquid fuels, thermal‐shielding materials, and ...

Geochemistry, Geophysics, Geosystems, 2018 The helium standard of Japan, referred to as HESJ, is an interlaboratory standard for the 3He/4He ratio. While the ratio of 3He and 4He of the HESJ was previously determined by a relative comparison to atmospheric helium, the absolute value of the 3He ...

Density of cosmic-ray neutrons in the atmosphere [PDF]
Journal of Geophysical Research, 1964 Neutrons are produced in the atmosphere by the interaction of cosmic-ray particles with the nuclei of nitrogen and oxygen. The density of these neutrons was determined experimentally by means of ionization chambers filled with B^(10), B^(11)F_3, and argon.
