Optimizing Processing and Formulation Strategies for Enhanced Thermal and Chemical Stability of Meltblown Polyphenylene Sulfide Nonwovens

open access: yesPolymer Engineering &Science, EarlyView.
PPS/PEI alloy fibers fabricated via meltblowing exhibit enhanced thermal stability with less than 10% shrinkage at 180°C, superior chemical resistance, and a high LOI of 34. ABSTRACT Polyphenylene sulfide (PPS) meltblown nonwovens are attractive for high‐performance filtration and protective applications owing to their intrinsic chemical resistance ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).

Microphysical chemistry of fog–aerosol interactions over the northwest Atlantic Ocean during Fatima 2022

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Fifteen size‐resolved aerosol samples collected during marine fog, with adjacent ambient observations, show that coarse sea salt aerosol is rapidly grown and lost in the northwest North Atlantic Ocean except when subject to extreme winds. The persistence of fog in the absence of sea salt is determined by available fine‐mode aerosol, where greater ...

CONCERT: A Modular Reconfigurable Robot for Construction

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This paper presents CONCERT, a fully reconfigurable modular collaborative robot (cobot) for multiple on‐site operations in a construction site. CONCERT has been designed to support human activities in construction sites by leveraging two main characteristics: high‐power density motors and modularity. In this way, the robot is able to perform a
