Characterizing the microstructural transition at the gray matter-white matter interface: Implementation and demonstration of age-associated differences

NeuroImage
Background: The cortical gray matter-white matter interface (GWI) is a natural transition zone where the composition of brain tissue abruptly changes and is a location for pathologic change in brain disorders.

Neuroinflammation at the Gray–White Matter Interface in Active-Duty U.S. Special Operations Forces

Neurotrauma Reports
Emerging evidence from autopsy studies indicates that interface astroglial scarring (IAS) at the gray–white matter junction is a pathological signature of repeated blast brain injury in military personnel.

High-order replica bands in monolayer FeSe/SrTiO3 revealed by polarization-dependent photoemission spectroscopy

Nature Communications, 2021
The origin of the photoemission replica bands in monolayer FeSe/SrTiO3 remains controversial. Here, the authors perform angle-resolved photoemission spectroscopy with polarized photon on FeSe/SrTiO3 and observe high-order replica bands with high ...

Water enables mild oxidation of methane to methanol on gold single-atom catalysts

Nature Communications, 2021
It is important but challenging to oxidize methane by O2 into methanol under ambient conditions. Here, the authors achieved mild oxidation of methane into methanol over Au single atoms on black phosphorus nanosheets with the help of water under light ...

Facet-dependent electrooxidation of propylene into propylene oxide over Ag3PO4 crystals

Nature Communications, 2022
The electrooxidation of propylene into propylene oxide is important in many industrial sectors. Here, the authors demonstrate efficient and facet-selective formation of propylene oxide using Ag3PO4 cubes and investigate the reaction mechanism.

Effect of Temperature on the Dynamic Properties of Mixed Surfactant Adsorbed Layers at the Water/Hexane Interface under Low-Gravity Conditions

Colloids and Interfaces, 2020
An increase in temperature typically leads to a decrease in the interfacial tension of a water/oil interface. The addition of surfactants to the system can complicate the situation significantly, i.e., the interfacial tension can increase or decrease ...

Direct synthesis of extra-heavy olefins from carbon monoxide and water

Nature Communications, 2023
Fischer-Tropsch synthesis is challenged by the trade-off between enhancing C-C coupling and suppressing further hydrogenation of olefins. Here the authors break this challenge by developing a universal strategy to synthesis extra-heavy olefins from ...

Ambient-pressure hydrogenation of CO2 into long-chain olefins

Nature Communications, 2022
The conversion of CO2 by renewable power-generated hydrogen is a promising approach to a sustainable production of long-chain olefins. Here the authors report a Cu-Fe catalyst which achieves the hydrogenation of CO2 into long-chain olefins under ambient ...
