Multilayer diffusion-barrier composites based on microfibrillated cellulose from wood, bacterial and algae sources

This work is driven by the effort towards increased environmental sustainability and aims to develop a new food packaging material based on renewable materials, and more specifically cellulose as the most abundant biomass resource on Earth. Focus was on mi ...

In-Situ FTIR and Laser Induced Fluorescence RONS Characterization of Atmospheric Pressure Nanosecond-Pulsed Surface DBD Plasma for Indirect Treatments of E. Coli

Ivo Furno, Fabio Avino, Rita Agus, Lorenzo Ibba

We study the bactericidal efficacy of surface dielectric barrier discharge low-temperature plasma treatments, powered by nanosecond high voltage pulses. We achieve similar to 4-log reduction in Escherichia coli population, after 10 min treatments, at a dis ...

Incorporation of Lignin in Bio-Based Resins for Potential Application in Fiber-Polymer Composites

Mário Alexandre De Jesus Garrido, Mateus De Assunção Hofmann

Bio-based resins, obtained from renewable raw materials, are a more sustainable alternative to oil-based resins for fiber-reinforced polymer (FRP) composites. The incorporation of lignin in those resins has the potential to enhance their performance. This ...

Salt-mediated inactivation of influenza A virus in 1- μl droplets exhibits exponential dependence on NaCl molality

Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Aline Laetitia Schaub, Shannon Christa David, Walter Hugentobler, Céline Terrettaz, Laura Costa, Laura José Costa Henriques

Influenza A virus (IAV) spreads through airborne particles ranging from sub-micrometer to millimeter-sized droplets. The stability of airborne IAV remains difficult to estimate and depends, among others, on the respiratory matrix composition and the size-d ...

Lifetime of dielectric elastomer actuators under DC electric fields

Fabio Beco Albuquerque

Dielectric elastomer actuators (DEAs) are interesting soft actuators compared to other actuation technologies owing to large achievable actuation strains, high energy density and fast actuation. However, because DEAs need to be operated under high electric ...

Human Emissions of Size-Resolved Fluorescent Aerosol Particles: Influence of Personal and Environmental Factors

Dusan Licina, Shen Yang

Human emissions of fluorescent aerosol particles (FAPs) can influence the biological burden of indoor air. Yet, quantification of FAP emissions from human beings remains limited, along with a poor understanding of the underlying emission mechanisms. To red ...

Influence of humidity, temperature and prestretch on the dielectric breakdown strength of silicone elastomer membranes for DEAs

Herbert Shea, Fabio Beco Albuquerque

Humidity, temperature and membrane prestretch influence the dielectric breakdown strength of elastomer membranes. These three factors thus also influence the maximum force and strain that dielectric elastomer actuators (DEAs) can generate, as the Maxwell p ...

Glass transition evaluation of commercially available epoxy adhesives for strengthening of steel structures with bonded CFRP plates

Ardalan Hosseini, Julien Michels

In the current study, the glass transition and tensile behavior of three different cold-curing two-component epoxies, commercially available as structural adhesives for carbon fiber reinforced polymer (CFRP) strengthening of concrete and steel structures, ...

Effects of humid air on aerodynamic journal bearings

Jürg Alexander Schiffmann, Eliott Philippe Guenat

The development of aerodynamic bearings applications where ambient conditions cannot be controlled (e.g., for automotive fuel cell compressor) raises the question of the effects of condensation in the humid air on perfor-mance. A modified Reynolds equation ...

Curing kinetics and thermomechanical properties of latent epoxy/carbon fiber composites

Véronique Michaud, Pierre-Etienne Bourban, Sara Dalle Vacche

In this work, resins based on diglycidyl ether of bisphenol A (DGEBA) epoxy and a latent hardener, dicyandiamide (DICY), as well as carbon fiber (CF) composites based on them, were prepared with three commercial accelerators: a methylene bis (phenyl dimeth ...
