Scalable, Microwave‐Enabled Synthesis of Ternary WxTi1‐xO2 and Heterostructured TiO2‐WO3‐x Colloidal Nanocrystals: Carrier Dynamics and Photocatalytic Properties

Advanced Science, EarlyView.
Two microwave‐assisted synthetic methods, specifically a one‐pot and a seeded‐growth approach, are developed within a hydroalcoholic solution for the growth of single‐phase ternary WxTi1‐xO2 and heterostructured TiO2‐WO3‐x colloidal nanocrystals. Both types of nanocrystals show significant photocatalytic activity for 4‐methoxybenzyl alcohol oxidation ...

Label‐Free Molecular Characterization of Protein Aggregates in Differentiated Astrocytes

Advanced Science, EarlyView.
Mid‐infrared photothermal microscopy enables label‐free structural, molecular, and functional imaging of protein aggregates in astrocyte cells. The processes of astrocytes differentiated on a nanomaterial interface are characterized by α‐helical signatures combined with enhanced interfacial thermal resistance properties, while the cell soma of non ...

Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths

Advanced Science, EarlyView.
Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...
