Using a Zero‐Strain Reference Electrode to Distinguish Anode and Cathode Volume Changes in a Solid‐State Battery

Advanced Materials Interfaces, EarlyView.
Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.

L’impact environnemental d’une habitation écologique

Revue des Énergies Renouvelables, 2010
Une maison écologique, désigne plus un concept qu’un type défini d’habitation. L’idée est de combiner les différents modes de chauffage, de ventilation, d’alimentation des appareils pour réduire massivement la consommation d’énergie, donc une ...

Digital Economy: The Evolution of the Digital Economy

Ubiquity, 2023
We are in the early stages of a historical transition from the industrial economy of the past two centuries to a new kind of a 21st century digital economy. This transition is being driven by dramatic advances in digital technologies and the internet over the past two decades, as well as the more recent advances in big data and artificial intelligence.

Hybridization of Gap Plasmons and Grating‐Coupled Surface Plasmon Polaritons in Metal Nanoparticle Cluster Arrays on a Mirror

Advanced Optical Materials, EarlyView.
Here we use a template‐assisted self‐assembly approach of metal colloids onto metal films to produce hybrid plasmonic metasurfaces that integrate nanoparticle‐on‐mirror cavities with periodic metal colloid arrays. The resulting coupling between gap plasmons and grating‐coupled surface plasmon polaritons enables programmable hybrid modes with tailored ...

Aberrations‐Corrected Ratiometric Parameters and PLQYs for Upconversion Thermometry in Hexagonal NaYF4:Yb3+,Er3+ and NaYF4:Yb3+,Tm3+ in Micro and Nanoscale Phosphors Using Novel Integrating Sphere Setup

Advanced Optical Materials, EarlyView.
Each optical system introduces aberrations in the reading of photoluminescence, which makes the signal dependant on the lab equipment. Here, a calibrated system is used to obtain the PLQYs and ratiometric parameters of popular upconverters to be used in thermometry.

Pyridinium Cations Act as Charge Reservoirs in Expanded Halide Perovskite Analogs at High Pressure

Angewandte Chemie, EarlyView.
Redox‐innocent pyridinium derivatives can act as charge reservoirs in expanded tin‐iodide perovskite analogs. Material compression reduces the energy gap between the pyridinium π* acceptor orbital and the valence‐band maximum, facilitating electron transfer from the framework to the molecules and thereby significantly increasing electronic conductivity

Determinants of the Informal Economy in MENA Economies

Eskişehir Osmangazi Üniversitesi Sosyal Bilimler Dergisi, 2018
Using data from a panel of 23 Middle East and North African (MENA) economies over the years between 1999-2015, this paper examines the determinants of the shadow economy in this region. Specifically, we reexamine the economic and social variables used in the cross-country empirical literature on the shadow economy and compare them with those of the ...

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Anion Engineering of Surface Frustrated Lewis Pairs for Light‐Assisted CO2 Hydrogenation to Methanol

Angewandte Chemie, EarlyView.
Anion engineering through nitrogen incorporation regulates the local coordination environment and promotes the formation of defect‐associated Ga–O/N frustrated Lewis pairs in non‐stoichiometric zinc gallium oxide. The engineered surface sites facilitate heterolytic H2 splitting, while the modified electronic structure enhances light utilization ...
