Room Temperature Synthesis and Photopatterning of Mesoporous Titanium Dioxide Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
A nanofabrication strategy combining deep‐UV photolithography with block copolymer self‐assembly enables direct patterning and mineralization of mesoporous TiO2 thin films at room temperature. Photocatalytic titanium oxo‐clusters promote polymer degradation under UV irradiation, enabling multiscale control over porosity, film thickness, and lateral ...

Enhancing Organic Light‐Emitting Diode Performance Using Naturally Derived Diatomite: A Cost‐Effective and Eco‐Friendly Strategy

open access: yesAdvanced Optical Materials, EarlyView.
Diatomite‐based light extraction structures enable enhanced photon outcoupling through multi‐angle scattering and far‐field redistribution. By harnessing the unique scattering behavior of diatomite, this approach introduces randomly oriented scattering centers that effectively reshape internal light propagation.

Hierarchical Twist: Chirality Across Scales in Cellulose Cholesterics

open access: yesAdvanced Optical Materials, EarlyView.
Hierarchical left‐ and right‐handed chiral nematic structures are observed in a solvent‐free thermotropic cellulose derivative. Free‐standing films show hierarchical twisted structures whose pitches respond differently to uniaxial strain: left‐handed pitches increase, ones decrease.

Ordered Mesostructured CdS Nanowire Arrays with Rectifying Properties

open access: yesNanoscale Research Letters, 2009
Highly ordered mesoporous CdS nanowire arrays were synthesized by using mesoporous silica as hard template and cadmium xanthate (CdR2) as a single precursor. Upon etching silica, mesoporous CdS nanowire arrays were produced with a yield as high as 93 wt%.

Spectroscopic Ellipsometry Characterization and Radiative Limit Modeling of Bismuth‐Based Perovskite‐Inspired Absorbers for Indoor Photovoltaics

open access: yesAdvanced Optical Materials, EarlyView.
This study determines the optical constants of two lead‐free perovskite‐inspired materials (PIMs), Cu2AgBiI6 and Cs3Bi2I6Br3, promising for indoor light conversion. The optical constants are applied to simulate photovoltaic device optics, and thereupon, revise the theoretical limits for photocurrent generation and power conversion efficiency, providing

On–Off Switchable Micromotors for Use in Steerable Microvehicles

open access: yesAdvanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,
