Highly Stable Perovskite Solar Cells Using Graphene and its Derivatives: A Review

open access: yesAdvanced Materials Interfaces, EarlyView.
Graphene and its derivatives (GO, rGO, GQDs) are key to solving the critical instability of perovskite solar cells (PSCs). This review systematically explores the multifunctional roles of these 2D materials in enhancing PSC durability. When integrated into electrodes, transport layers, and encapsulation, their exceptional barrier properties and ...

Bacterial‐Responsive and Dye‐Selective Janus Membranes via Laser‐Directed Fluorinated Graphene Interfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
This work highlights laser‐engineered wettability switching of fluorine‐doped laser‐induced graphene (F‐LIG) for antibacterial, thickness‐tunable, dye‐selective filtration. Precise CO2‐laser patterning modulates surface roughness and hydrophobicity, suppressing bacterial adhesion and disrupting cell membranes, while Janus F‐LIG/F‐PPI structures enable ...

Realizing Vertical Etch Profiles in Fluorine‐Rich Ar/CF4 Plasma

open access: yesAdvanced Materials Interfaces, EarlyView.
Lowering the electron temperature (Te) in fluorine‐rich Ar/CF4 plasma induces a dramatic transition from isotropic to highly vertical etch profiles. Enhanced sidewall passivation, driven by an increased CFx/F ratio at low Te, enables anisotropic etching even in F‐rich chemistries.

Modification of Self‐Assembled Monolayers by Electron Irradiation as a Tool for Surface Engineering, Lithography, and Nanofabrication

open access: yesAdvanced Materials Interfaces, EarlyView.
This study reviews the relevant work regarding the modification of self‐assembled monolayers (SAMs) by electron irradiation. Both fundamental aspects and the related implications and applications are addressed. The latter includes tuning SAM properties, preparation of binary SAMs, conventional and chemical lithography, carbon nanomembranes, control of ...
