In Vitro Evaluation of Antibacterial Properties of NIR-Light Responsive Alginate Hydrogels Embedding Polydopamine Nanoparticles

Sarah Defrançois, Alexandre Barras, Mickaël Maton, Patrice Woisel, Feng Hildebrand, Nicolas Blanchemain, Rabah Boukherroub, Joël Lyskawa

acterial infections are one of the most serious health problems worldwide and represent a significant threat to humans. In this article, we designed an injectable alginate-based hydrogel embedding polydopamine nanoparticles (nPDA) and applied it as a (nano)phototherapeutic agent and nanocarrier for…

Theoretical Framework for Semitransparent Organic Photovoltaics: Bridging Material Design with Optical Engineering

Baozhong Deng, Zhouyi Lu, Kaiwen Zheng, Bin Wei, Gaëtan Lévêque, Bruno Grandidier, Jianhua Zhang, Tao Xu

Semitransparent organic photovoltaics (ST‐OPVs) hold great promise for building‐integrated applications but encounter a critical trade‐off between power conversion efficiency (PCE) and visible transparency. This work addresses this challenge by introducing a novel theoretical framework that…

Silicate–sulfide interaction within quenched melts of space weathered Ryugu grains

Sylvain Laforet, Hugues Leroux, Corentin Le Guillou, Maya Marinova, Adrien Neri, Adrien Teurtrie, Francisco de la Peña, Damien Jacob, Alexandre Fadel, David Troadec

The first few microns of the surface of airless bodies are subject to severe changes due to the harsh environment of space, known as space weathering. The Hayabusa2 sample return mission from the asteroid Ryugu provides the first opportunity to study these effects on a carbonaceous and hydrated…

Topology optimization of phoxonic crystals for maximizing dual bandgaps using GA-SIMP method

Bin Li, S S Nanthakumar, Yan Pennec, Bahram Djafari-Rouhani, Xiaoying Zhuang

Phoxonic crystals are photonic-phononic or optomechanical periodic structures that simultaneously exhibit dual bandgaps. This allows for the confinement of both optical and elastic waves in cavities and waveguides, providing a powerful platform for novel optomechanical devices and systems. The…

Optimization of CRC-Based Single-Bit Error Correction Using a Perfect Hash Table Structure

Zouhair Ziani, Stéphane Coulombe, François-Xavier Coudoux, Patrick Corlay

This work introduces a novel approach for correcting a single-bit error in a CRC-protected message, which is based on a perfect hash table that can be queried by a non-zero CRC syndrome. The paper primarily focuses on presenting the new table structure and includes a comparative analysis of various…
