The Role of Interfacial Energetics and Defects on The Efficiency of Tin Perovskite Solar Cells
ABSTRACT Tin perovskites are emerging as a sustainable alternative to lead‐based photovoltaics, yet their efficiency remains limited by energy‐level mismatch and intrinsic instability from tin oxidation. Progress is further hindered by inconsistent electrical behavior, obscuring the true bottlenecks of device performance.

Assessment of early-modern observations of comets and supernovae: Focus on pre-telescopic European astrometric and physical data [PDF]
The two-century period prior to the publication of Newton's Principia (first edition 1687; third edition 1726) was most important in terms of the radical changes that occurred in the observation, perception, and understanding of celestial objects that in

Search for the True Parent Body of the Phoenicid Meteor Shower
In 2024, Ďurišová et al. found that the meteor shower Phoenicids, IAU No. 254, code PHO, can originate in the nuclei of three comets, 46P/Wirtanen, 104P/Kowal 2, and 289P/Blanpain.

Mammalian Osteoderm Ultrastructure in the Armored Acomys Spiny Mouse Tail
The ultrastructure of armored platelets – termed osteoderms – in the tail skin of Acomys cahirinus spiny mice is characterized using 2D and 3D microscopy methods. The imbricated structure is composed of calcium phosphate biomineral and has select structural elements that are bone‐like and tooth‐like in nature.

Gas Dynamics and Kinetics in the Cometary Coma: Theory and Observations
Our ability to describe the physical state of the expanding coma affects fundamental areas of cometary study both directly and indirectly. In order to convert measured abundances of gas species in the coma to gas production rates, models for the ...

COMET Functions as a PCH2 Cofactor in Regulating the HORMA Domain Protein ASY1
The formation of the chromosome axis is key to meiotic recombination and hence the correct distribution of chromosomes to meiotic products. A key component of the axis in Arabidopsis is the HORMA domain protein (HORMAD) ASY1, the homolog of Hop1 in yeast

Solar Sail Optimal Performance in Heliocentric Nodal Flyby Missions
Solar sails are propellantless propulsion systems that extract momentum from solar radiation pressure. They consist of a large ultrathin membrane, typically aluminized, that reflects incident photons from the Sun to generate thrust for space navigation ...
