Non-Destructive Electrochemical Testing for Stainless-Steel Components with Complex Geometry Using Innovative Gel Electrolytes

Metals, 2018
Corrosion can be a problem for stainless steels in chloride-containing or other aggressive environments, especially when they are formed as components with complex shapes.

Abrupt appearance of the domain pattern and fatigue of thin ferroelectric films

, 2000
We study the domain structure in ferroelectric thin films with a `passive' layer (material with damaged ferroelectric properties) at the interface between the film and electrodes within a continuous medium approximation.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Passive Amplification Effect in Thin Pyroelectric Films

Molecular Crystals and Liquid Crystals, 2011
Here we continue the description of the previously found passive amplification effect in thin pyroelectric films placed on a massive heat-conducting substrate. We show that in the definite modulation frequency range the amplification effect occurs i.e., a current generated by a thin pyroelectric film placed on substrate exceeds that in freely suspended

Cool Kitchen: Processing Starch and Eggshell Powder into Sustainable Coatings for Passive Daytime Cooling

Advanced Functional Materials, EarlyView.
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.

Semiconducting behavior of pure copper in alkaline solutions

Egyptian Journal of Petroleum, 2015
The corrosion resistance of passive film is correlated with its semiconducting properties, which can be measured by the Mott–Schottky analysis in high frequency domain.

Reducing Open‐Circuit Voltage Losses in Wide‐Bandgap FAPbBr3 Perovskite Solar Cells for Continuous Unassisted Light‐Driven Water Splitting

Advanced Functional Materials, EarlyView.
The combination of formamidinium thiocyanate and 1,3‐propane diammonium iodide for bulk and top‐surface passivation, and a ternary fullerene blend to improve energy band alignment, suppresses energy losses in wide‐bandgap FAPbBr3 perovskite solar cells.

Electrochemical Behavior and Compositions of Passive Films of Amorphous Ni-P Coating in Acidic Environment

International Journal of Electrochemical Science, 2016
Amorphous Ni-P coating without pores was prepared by electroless plating. The electrochemical behavior of the as-plated Ni-P coating was investigated by potentiodynamic testing in 5 wt. % sulfuric acid solution. Results indicated that the high-phosphorus

Are We Defended? Conflicting Representations of War in Pre-War France [PDF]

, 2008
This article examines contradictions in the way that war was represented to the French population in the interwar period. It argues that an ‘official’ representation of war gave an impression of France as a secure nation; people were discouraged from ...
