Probing the nuclear equation-of-state and the symmetry energy with heavy-ion collisions

open access: yesEPJ Web of Conferences, 2014
The present status of studies aimed at constraining the nuclear equation of state with heavy-ion collision dynamics is presented. Multifragmentation phenomena, including their isotopic distributions, charge correlations and emission time-scales, may ...

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

open access: yesAngewandte Chemie International Edition, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

Jet Drift in Heavy-Ion Collision: Acoplanarity and v2 [PDF]

open access: yesEPJ Web of Conferences
We introduce a sub-eikonal anisotropic contribution to jet-broadening, “jet drift,” that couples to the flow of the nuclear medium, showing that this effect results in a deflection of hard partons, and thus jets, in the direction of the medium flow.

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Predicting quadrupole deformation via anisotropic flow and transverse momentum spectra in isotopic $$\mathbf {{}^{128-135}_{\qquad \,54}\textrm{Xe}}$$ 54 128 - 135 Xe collisions at LHC

open access: yesEuropean Physical Journal C: Particles and Fields
In the hydrodynamical description of heavy-ion collisions, the elliptic flow $${\textrm{v}}_{2}$$ v 2 and triangular flow $${\textrm{v}}_{3}$$ v 3 are sensitive to the quadrupole deformation $${\beta _{2}}$$ β 2 of the colliding nuclei.

Studying Heavy Ion Collisions Using Methods From Cosmic Microwave Background (CMB) Analysis

open access: yesEPJ Web of Conferences, 2014
We present and discuss a framework for studying the morphology of high-multiplicity events from relativistic heavy ion collisions using methods commonly employed in the analysis of the photons from the Cosmic Microwave Background (CMB).

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...
