Relativistic corrections to inverse Bremsstrahlung in the solar interior
, 1995 The cross-section of free-free transitions (inverse bremsstrahlung) in the solar interior is calculated including corrections due to relativistic dynamics and the distribution function of the electrons. The reduction of the radiative opacity due to these

Advanced Science, EarlyView.Facet‐engineered PVP‐capped CuFeSe2 nanocrystals exhibit potent, selective antifungal activity by strongly binding cell‐wall mannan, enabling vacuolar entry and organelle disruption. High‐index facets show superior mannan affinity, validated by theoretical calculations and experiments. CFS‐P induces vacuolar cavitation, mitochondrial abnormalities, and

Assessing the Observability of Deep Meridional Flow Cells in the Solar Interior
The Astrophysical JournalMeridional circulation regulates the Sun’s interior dynamics and magnetism. While it is well accepted that meridional flows are poleward at the Sun’s surface, helioseismic observations have yet to provide a definitive answer for the depth at which those ...

What have we learned about the solar interior from solar oscillations? [PDF]
, 1995 After a brief review of the discovery and properties of solar oscillations, I summarize the significant advances in our knowledge of the Sun`s interior structure achieved by using solar oscillation frequency data.

The Sun’s Interior Structure and Dynamics, and the Solar Cycle
, 2014 The Sun’s internal structure and dynamics can be studied with helioseismology, which uses the Sun’s natural acoustic oscillations to build up a profile of the solar interior.

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction
Advanced Science, EarlyView.The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.

Large-Scale Dynamics of the Convection Zone and Tachocline
Living Reviews in Solar Physics, 2005 The past few decades have seen dramatic progress in our understanding of solar interior dynamics, prompted by the relatively new science of helioseismology and increasingly sophisticated numerical models.

Advanced Science, EarlyView.A scalable radiative cooling fabric engineered with a multi‐layer assembly core–shell structure and integrated photoluminescent materials is reported. The fabric exhibits remarkable environmental stability, including UV resistance, mechanical durability, hydrophobicity, stain resistance, thermal stability, and flame retardancy, demonstrating its ...

Asphericity of the Base of the Solar Convection Zone
The Astrophysical JournalWe have used solar oscillation frequencies and frequency splittings obtained over solar cycles 23 and 24 to investigate whether the base of the solar convection zone shows any departure from spherical symmetry.

Hydrophobicity Modulated Interfacial Water Distribution for Enhanced Kinetics of HER
Advanced Science, EarlyView.In electrocatalysis, hydrophilic structures improve interfacial water management by forming a continuous, compact water film that facilitates proton/hydrogen transport, thereby lowering the effective adsorption free energy of H*. By contrast, hydrophobic structures enable rapid gas transport and promote the capture and local enrichment of gaseous ...
