Recycling of Polymer Components From Waste Face Masks for Asphalt Modification: A Mini Review

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT The COVID‐19 pandemic greatly increased plastic waste through widespread personal protective equipment (PPE) use, creating a serious environmental challenge. Disposable face masks (FM), primarily composed of non‐biodegradable polypropylene, account for an estimated 86 million units discarded monthly, leading to significant environmental ...

Structure of the Multiphase Chalcolithic Tell Chiselet–Grădiștea Fundeanca (Romania) From SH‐Wave Full‐Waveform Inversion, Borehole Geophysics and Coring

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The emergence and development of settlement mounds, also called tells, is of major interest for the analysis of socio‐economic transformations occurring in the lower Danube plain during the East European Chalcolithic period. In this context, the multiphase chronology and structural layout of tells are highly relevant indicators, but small ...

Elemental Analysis of Catalysts in a Fixed‐Bed Reactor by Laser‐Induced Breakdown Spectroscopy

open access: yesChemCatChem, EarlyView.
The “Elemental Composition” provides information about promoters and poisons found in heterogeneous catalysts. Access to this piece of information under reaction conditions remains yet an unsolved challenge. This work explores the potential and limitations of laser‐induced breakdown spectroscopy (LIBS) as an in situ reactor diagnostic technique ...

Perturbative methods for inverse problems on degenerate differential equations

open access: yesBruno Pini Mathematical Analysis Seminar, 2012
Pertubation results for linear relations satisfying a resolvent condition of weak parabolic type are established. Such results are applied to solve some inverse problems for degenerate differential equations, supplying a new method which avoids any fixed-
