Development of non‐destructive analytical strategies based on Raman spectroscopy and complementary techniques for Mars Sample Return tested on Northwest Africa 1950 Martian meteorite

Journal of Raman Spectroscopy, Volume 53, Issue 12, Page 2068-2085, December 2022., 2022
A non‐destructive analytical methodology, based on Raman microscopy (single point and imaging), micro‐energy dispersive X‐ray fluorescence (μED‐XRF) imaging analysis, and scanning electron microscopy coupled to energy dispersive spectroscopy (SEM‐EDS), is suggested for a first analytical characterization for the Martian samples that will be taken to ...

How companies use typeface design to engage consumers in charitable activities

Psychology &Marketing, Volume 40, Issue 1, Page 107-123, January 2023., 2023
Abstract This research examines how the typeface design in a charitable appeal affects consumers' evaluations of the ad and, in turn, their willingness to engage in the advertised charitable activities. We propose that the typeface's simulation of a handwritten note creates a sense of connectedness to the information sender (e.g., organization, brand),

Structure–Property Relationships of Shape Memory, Semicrystalline Polymers Fabricated by In Situ Polymerization and Crosslinking of Octadecyl Acrylate/Polybutadiene Blends

Macromolecular Rapid Communications, Volume 44, Issue 1, January 2023., 2023
The development of a semicrystalline, shape memory polymer is synthesized by simultaneous free radical polymerization and crosslinking in a blend of polybutadiene and octadecyl acrylate, enabling the melt fabrication of complex 3D molded shapes with potential use in anticounterfeiting and antitampering applications.

Low‐Velocity Penetration Impact Behavior of Triply Periodic Minimal Surface Strut‐Based Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS)‐based lattices are gaining attention for their multifunctional properties in applications as aeronautics and automotive, which involve low‐velocity impact loading. This work evaluates the low‐velocity penetration impact behavior of five distinct TPMS architectures.

Scalable Manufacturing of Radiation‐Tolerant Potentiometric Electrodes: A Systematic Transition from Laboratory to Semiautomated Fabrication

Advanced Engineering Materials, EarlyView.
Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived

Photo‐Assisted Zn‐Iodine Battery via Bifunctional Cathode with Iodine Host and Solar Response Boost

Advanced Functional Materials, EarlyView.
A bifunctional cathode based on BiOI materials is developed for photo‐assisted Zn‐iodine batteries, serving as both an iodine host and a solar‐responsive material. This design enables dual reaction routes involving vacancy‐based iodine storage and reversible two steps iodine redox.

Modeling heat transfer and transcrystallization kinetics during processing of polymer‐based composites materials

Polymers for Advanced Technologies, Volume 34, Issue 2, Page 655-675, February 2023., 2023
Abstract Transcrystallization phenomena is a key issue to master for better understanding the role on the fiber‐matrix interface in composites materials behavior during and after processing. In this paper, a non‐isothermal kinetics model is presented to consider crystallization in fiber‐based composite with thermoplastic matrix.
