Tailoring the Crystallization Behavior of Mixed Lead‐Tin Mixed‐Halide Perovskites for Optimal‐Bandgap Solar Cells

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Carefully tuning the composition of mixed lead‐tin mixed iodide‐bromide perovskites results in an optimal‐bandgap semiconductor for solar energy conversion. Homogenous crystallization of this perovskite involves a short time delay between deposition of the precursor solution and applying an antisolvent. Using a bulk additive and top surface passivation

Persistent Magnetism and Tunable Doping of Monolayer Graphene via Europium Density Modulation

Advanced Science, Volume 13, Issue 7, 3 February 2026.
The modulation of europium density at the graphene/rhenium interface enables electron doping of monolayer graphene both beneath and beyond the van Hove singularity. The interfacial europium is ferromagnetic, with a transition from a mixed Eu(II)/Eu(III) valence in the dense phase to a pure Eu(II) state in the diluted phase.

A randomised controlled trial on cross‐linking protocols for the treatment of progressive keratoconus using isoosmolar and hypoosmolar riboflavin with the addition of sterile water in thin corneae

Acta Ophthalmologica, Volume 104, Issue 1, Page e63-e74, February 2026.
Abstract Purpose To present the outcomes of a randomised clinical trial for the treatment of progressive keratoconus using different kinds of riboflavin and the addition of sterile water in thin corneae. Methods A randomised study using epithelium‐off corneal cross‐linking (CXL) with continuous UVA irradiance 9 mW/cm2 for 10 min (total fluence 5.4 J ...

Abnormal Expansion Along the Synthesis of Zinc Stannate: A Way for Porous Ceramics Without Addition of Pore Generators

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
The abnormal expansion associated with the simultaneous synthesis and sintering of Zn2SnO4 from ZnO and SnO2 is due to the reaction mechanism and correlated with the conversion. This phenomenon opens the way to manufacture porous ceramics without the addition of pore generators, simplifying the process, and especially the thermal treatment.

Leveling coatings for reducing the atomic oxygen defect density in protected graphite fiber epoxy composites [PDF]

Pinholes or other defect sites in a protective oxide coating provide pathways for atomic oxygen in low Earth orbit to reach underlying material. One concept of enhancing the lifetime of materials in low Earth orbit is to apply a leveling coating to the ...
