Role of Rare‐Earth Lanthanum Doping on Electrical Performance and Stability of Atomic Layer Deposition Processed Indium Oxide Thin‐Film Transistors

Advanced Electronic Materials, EarlyView.
The work demonstrates La doping in In2O3 via ALD super‐cycles. The strong La─O bond suppresses oxygen vacancies, resulting in a decrease in mobility and a positive shift in threshold voltage. The effective suppression of VO decreases oxygen‐related defects under gate bias, leading to exceptional negative bias stability.

Enabling Long Term, Shelf‐Stable Perovskite Solar Cells: Alumina Barriers to Protect Perovskite Devices from Moisture and Oxygen

Advanced Energy Materials, EarlyView.
This study reports a packaging strategy for perovskite photovoltaic devices using atomic layer deposition (ALD) of aluminum oxide. Through optimization of deposition temperature and oxidant chemistry, researchers develop a 50 nm barrier layer with superior water vapor (WVTR) and oxygen transmission rates (OTR).

Integrated Assessment of Lipid Oxidation and Off‐Flavor Formation in Plant Protein Powders

Journal of the American Oil Chemists' Society, EarlyView.
Impact of residual lipids on oxylipin and off‐flavor formation in commercial plant proteins: A detailed analysis of precursor‐product relationships by GC‐FID, LC‐MS/MS, and GC‐MS. ABSTRACT The widespread adoption of plant proteins is hindered by their inherent off‐flavors, often linked to lipid oxidation products.

Understanding Oxide Surface Stability: Theoretical Insights From Silver Chromate

Advanced Physics Research, EarlyView.
Seven low‐index Miller surfaces, comprising 46 distinct terminations, were systematically investigated to determine their surface free energies as functions of the chemical potentials of the system constituents. The competition among these terminations gives rise to temperature‐dependent stability crossovers that dynamically reshape the surface energy ...
