Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Robust Interlayer Exciton Interplay in a Twisted van der Waals Heterotrilayer on a Broadband Bragg Reflector up to Room Temperature

Advanced Functional Materials, EarlyView.
In this work, we highlight a unique material platform capable of producing three distinct room temperature (RT) photoluminescence (PL) resonances from spatially separated regions composed of a heterobilayer (HBL), a homobilayer (HoBL), and an heterotrilayer (HTL) transition metal dichalcogenide (TMD) heterostructures configuration on a highly ...

Decoupling Light Absorption From Photocatalytic Reactivity in TiO2 via Defect and Interfacial Engineering

Advanced Functional Materials, EarlyView.
A hybrid photoprotective material integrates N‐doped TiO2 with a metal‐phenolic network (MPN) to achieve broad‐spectrum attenuation and robust reactive oxygen species (ROS) suppression. Nitrogen doping extends attenuation into the UVA/high energy visible light (HEV) regions and facilitates fast charge recombination to inhibit ROS formation.

Ocular refraction: heritability and genome-wide search for eye morphometry traits in an isolated Sardinian population [PDF]

, 2005
No genes influencing oculometric phenotypes have yet been identified, despite it being well known that eye morphometry is involved in refraction and that genetics may play an important role.

Gate‐Programmable Linearization of Atomically Thin Nanoelectromechanical Resonators via Duffing Nonlinearity Cancellation

Advanced Functional Materials, EarlyView.
Gate bias is used to cancel Duffing nonlinearity in atomically thin MoS2 drumhead resonators, switching their response from hardening to softening and creating a nearly linear operating point. This electrical control suppresses hysteresis, enables stronger linear drive, and improves signal‐to‐noise ratio, offering a practical route to stable 2D NEMS ...
