Advanced Functional Materials, EarlyView.Solvent‐composition‐controlled film formation enables high‐performance (efficiency = 18.66%) and air‐stable terpene‐processed organic solar cells. An optimized eucalyptol/tetralin ratio of 50:50 (v/v) balances molecular solvation and aggregation kinetics, producing favorable nanoscale phase separation and vertical composition gradients.

Bio‐Inspired Multifunctional Superhydrophilic Coatings With Remarkably Fast Self‐Healing Abilities
Advanced Functional Materials, EarlyView.We developed bio‐inspired multifunctional hydrogel‐based coatings that exhibit extremely fast/repeatable self‐healing abilities, long‐lasting anti‐fogging performance, superhydrophilicity in air, and underwater superoleophobicity. By doping multivalent metal‐ions into the hydrogel networks, which promoted hydrogen bonding formation and enhanced the ...

Advanced Functional Materials, EarlyView.Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

Solar system tests for realistic f(T) models with non-minimal torsion–matter coupling
European Physical Journal C: Particles and Fields, 2017 In the previous paper, we have constructed two f(T) models with non-minimal torsion–matter coupling extension, which are successful in describing the evolution history of the Universe including the radiation-dominated era, the matter-dominated era, and ...

Planet formation and the evolution of the Solar System [PDF]
Physica Scripta, 2019 Abstract The Capture Theory gives planet formation through a tidal interaction between a condensed star and a protostar within a dense embedded stellar cluster. Initial extensive and highly eccentric planetary orbits decay and usually round-off in circumstellar material captured from the protostar.
