Subsurface Stabilization of Interstitial Pt Atoms on CeO2(111): Rethinking Single‐Atom Catalyst Architectures

open access: yesAngewandte Chemie International Edition, EarlyView.
By combining polarization‐resolved IRRAS on atomically flat CeO2(111) single crystals with quantitative XPS and DFT calculations, we identify an unusual subsurface interstitial configuration of Pt single atoms that gives rise to a previously unobserved, blue‐shifted CO vibrational mode.

Emerging research directions in nanoparticle‐based foam control for bioprocessing: a bibliometric approach

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Overfoaming remains a critical challenge in industrial bioprocesses, compromising mass transfer, operational stability, and downstream efficiency in bioreactors and wastewater treatment systems. This study provides a bibliometric and scientometric assessment of nanoparticle‐enabled foam control to map technological trends and identify research

Phase Transitions of Binary Lipid Mixtures: A Combined Study by Adiabatic Scanning Calorimetry and Quartz Crystal Microbalance with Dissipation Monitoring

open access: yesAdvances in Condensed Matter Physics, 2015
The phase transitions of binary lipid mixtures are studied by a combination of Peltier-element-based adiabatic scanning calorimetry (pASC) and quartz crystal microbalance with dissipation monitoring (QCM-D).

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

open access: yesCarbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Dry Vacuum Processing of Perovskite Films: Insights Into Growth and Precision Control Enabling Batch‐Stable High‐Efficiency Solar Cells

open access: yesCarbon Energy, EarlyView.
This work establishes a standardized, additive‐free dry vacuum sublimation process for perovskite solar cells. By uncovering atomic‐scale growth mechanisms, we demonstrate that sequential deposition provides superior film quality compared to co‐deposition.
