Mechanistic Insights into the Surface Instabilities of TiNb2O7, a High‐Power Li‐Ion Anode

open access: yesAdvanced Materials Interfaces, EarlyView.
TiNb2O7 is an attractive anode for Li‐ion batteries, particularly when safety is of the highest concern. However, despite operating at high potentials, electrolyte degradation is a major concern. It is demonstrated that throughout the entire charge‐discharge cycle a number of surface reactions occur which both produce gas and result in Ti dissolution ...

Anisotropic Wetting Behavior on Gradient Surface Structures Fabricated by Direct Laser Interference Patterning on Stainless Steel

open access: yesAdvanced Materials Interfaces, EarlyView.
In this work, anisotropic line‐like textures with gradually increasing spatial periods from 2.0 to 4.8 µm are fabricated on stainless steel by two‐beam Direct Laser Interference Patterning using a picosecond (ps)laser source. The spontaneous motion of water droplets deposited on these gradient structures in the direction of increasing periodicity is ...

Laser‐Induced Plasma Effects on Bond Breaking in High‐Density Polyethylene Pyrolysis

open access: yesAdvanced Materials Interfaces, EarlyView.
This study introduces a novel application of Laser‐Induced Breakdown Spectroscopy (LIBS) for bond breaking in high‐density polyethylene (HDPE), an area previously unexplored in laser‐plastic interactions. For the first time, a numerical model has been developed to differentiate between photon‐induced and laser field‐induced plasma, demonstrating the ...

Atomic‐Scale Mechanisms of Nucleation and Stabilization in CuCrO2 and CuFeO2 Delafossite Thin Films on Al2O3

open access: yesAdvanced Materials Interfaces, EarlyView.
In this work, a combination of 4D STEM phase reconstructions via iterative electron ptychography, spectroscopy, and conventional STEM imaging reveals detailed insights into the nucleation mechanism for the stable growth of Cu‐based delafossites on Al2O3 using CuCrO2 and CuFeO2 films grown via MBE as examples.
