Deciphering Redox Pathways in Aqueous Microdroplets: Simultaneous Production of Hydrogen Peroxide, Hydrogen, and Organics from Ethyl Palmitate as Renewable Feedstock

Sonam Rani, Hung V. Nguyen, Lingyang Zhu, Supriya Das et autres

Abstract Ultrasonication of biphasic mixtures involving water and oil forms water microdroplets, offering a promising platform that spontaneously generates hydrogen peroxide and hydrogen gas. However, the redox mechanisms underpinning these transformations are poorly understood, and most existing studies rely heavily on petroleum-derived …

Depolymerization of Kraft Lignin into a Redox-Active Small Molecule Utilizing the Redox Activities of Sonicated Emulsive Water Microdroplets (SEWMs)

Joaquín Rodríguez López, Supriya Das

Sonicated emulsive water microdroplets (SEWMs) provide a unique reaction environment that can be used to carry out chemical and redox reactions at rates that are distinct to bulk aqueous systems. The mechanical excitation required to form SEWMs creates a unique reactive environment …

D 0 -meson-tagged jet axes difference in proton-proton collisions at s = 5.02 TeV

S. Acharya, Apar Agarwal, Gianluca Aglieri Rinella, Luca Aglietta et autres

Heavy-flavor quarks produced in proton-proton (pp) collisions provide a unique opportunity to investigate the evolution of quark-initiated parton showers from initial hard scatterings to final-state hadrons. By examining jets that contain heavy-flavor hadrons, this study explores the effects of both perturbative and …

(Invited) Electrochemistry and Redox Reactivity within Sonicated Emulsive Water Microdroplets: A Novel Approach for Sustainable (Electro)Synthesis

Abdelilah Asserghine, Aravind Baby, Supriya Das, Gavin Hazen et autres

Recent years have seen an emergence of works investigating the chemical reactivity of water microdroplets generated via a variety of methods, including sprays, (sonicated) electrosprays, and sonicated water/oil emulsions.[1-4] These systems are reported to enable or accelerate a wide range of reactions, …

Forward-backward correlations: A probe to study dynamical fluctuations

Supriya Das, Saikat Biswas

The source of the fluctuations in the final state particles is the initial event-by-event fluctuation in energy density. Forward-Backward (F-B) correlation is one of the important probes to study such fluctuations. The results of F-B correlation are available in a wide range …

Measurement of $f_{1}$(1285) production in pp collisions at $\sqrt{s}$ = 13 TeV

Shreyasi Acharya, Apar Agarwal, Gianluca Aglieri Rinella, Luca Aglietta et autres

This study presents the first measurement of the $f_{1}$(1285) resonance using the ALICE detector in inelastic proton–proton collisions at a center-of-mass energy of 13 TeV. The resonance is reconstructed at midrapidity (|y|< 0.5) through the hadronic decay channel $f_{1}$(1285) → $K_{S}^{0}K^{±}π^{∓}$. Key …
