Azimuthally Symmetric Theory of Gravitation (I)
, 2009 From a purely none-general relativistic standpoint, we solve the empty space Poisson equation ($\nabla^{2}\Phi=0$) for an azimuthally symmetric setting, i.e., for a spinning gravitational system like the Sun.

Advances in Triboelectric Nanogenerators With Rotating Structure
Carbon Energy, EarlyView.The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

The Planets Mercury and Venus [PDF]
Nature, 1928 THROUGH the kindness of Dr. Deslandres, I followed Mercury here last spring and summer with the 33-inch refractor, and all recent observations confirm my 1927 results with the same instrument as to the correctness of the 88-day rotation period and as to the presence of whitish atmospheric veils of low albedo, which occasionally distort and conceal the ...

Carbon Energy, EarlyView.ABSTRACT The inherent hydroxide‐rich (OH⁻) environment in alkaline media facilitates the two‐electron oxygen reduction reaction (2e−ORR). However, the strong interaction between alkali metal cations and solvated water molecules significantly reduces the connectivity of the hydrogen bond network within the alkaline electric double layer, thereby ...

ChemPhysChem, EarlyView.The pentaPod (P5) concept unites tridentate and tripodal fragments to form molybdenum and tungsten catalytic Chatt‐type complexes for N2‐to‐NH3 reduction. Two pentaPod ligands, P5Me and P5Pln, are available with either two dimethylphosphine or phospholano (Pln) groups. The complexes enable the investigation of reactivity differences in N2 reduction and,

A New Hybrid Solid/Solvating Sulfur Conversion for Energy‐Dense Lithium‐Sulfur Batteries
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A moderately solvating electrolyte (1M LiTFSI in methoxyacetonitrile) offers hybrid solid/solvating conversion of sulfur, combining fast conversion kinetics and lean electrolyte operation. To boost the practical energy density of lithium‐sulfur batteries, replacing conventional solvating electrolytes with sparingly solvating ones has shown promise by ...

Formation of the Terrestrial Planets from a Narrow Annulus
, 2009 We show that the assembly of the Solar System terrestrial planets can be successfully modelled with all of the mass initially confined to a narrow annulus between 0.7 and 1.0 AU.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The structure, properties, preparation methods, and characterization techniques of BP. As a typical 2D layered material, black phosphorus (BP) demonstrates exceptional promise in various fields, particularly in energy storage for alkali metal‐ion batteries. However, its distinctive structure and properties, together with the compositional complexity of
