On the physics of fizzing: How bubble bursting controls droplets ejection

open access: yes, 2014
Bubbles at a free surface surface usually burst in ejecting myriads of droplets. Focusing on the bubble bursting jet, prelude for these aerosols, we propose a simple scaling for the jet velocity and we unravel experimentally the intricate roles of bubble

Real-Time Assessment of E-Cigarettes and Conventional Cigarettes Emissions: Aerosol Size Distributions, Mass and Number Concentrations

open access: yesToxics, 2019
Cigarette smoke is a complex mixture of chemical compounds which are emitted during the processes of tobacco combustion. Electronic cigarettes (e-cigs) are expected to produce less harmful compounds due to the absence of tobacco leaf combustion. However,

HARMLESS Early Warning System for Advanced Materials

open access: yesAdvanced Sustainable Systems, EarlyView.
The HARMLESS Early Warning System tackles Advanced Materials (AdMa) risk governance by providing a framework, organised in two tiers, underpinned with methods/tools to support risk assessors in the pre‐assessment preceding risk assessment. It allows for initial screening to identify AdMa with concerns considering exposure, hazards, sustainability and ...

Formulation and Process for Air Stable Zn‐Based Printed Flexible Electronics

open access: yesAdvanced Sustainable Systems, EarlyView.
A sustainable, screen‐printable zinc‐based ink combining micro‐ and nanoparticles with micro‐fibrillated cellulose enables flexible electronics with exceptional air stability. A multi‐step chemical sintering process boosts conductivity to 8.37 × 10⁵ S m−¹ among the highest for Zn inks, while maintaining performance after six months.
