Solid-phase excitation-emission matrix spectroscopy for chemical analysis of combustion aerosols.

PLoS ONE, 2021
Exposure to ultrafine combustion aerosols such as particulate matter (PM) from residential woodburning, forest fires, cigarette smoke, and traffic emission have been linked to adverse health outcomes.

Ordinal analysis applied to the results of positive matrix factorization of chemical ionization mass spectrometry data

MethodsX, 2020
As an innovative analytical approach ordinal analysis is applied to positive matrix factorization (PMF) analysis outputs to identify the most important species and factors in chemical ionization mass spectrometry (CIMS) data. The procedure and outcome of

Comparing matrix models and QCD lattice data with chemical potential [PDF]

Nucl.Phys.B(Proc.Suppl.)129&130(2004)527, 2003
We present a quantitative analysis of the microscopic Dirac spectrum which is complex in the presence of a non-vanishing quark chemical potential. Data from quenched SU(3) lattice simulations for different volumes V and small values of the chemical potential are compared to analytical predictions from matrix models.

Methods for the analysis of endocrine disrupting chemicals in selected environmental matrixes

Environmental Research, 2021
Endocrine disrupting chemicals (EDCs) are heterogenous in structure, chemical and physical properties, and their capacity to partition into various environmental matrixes. In many cases, these chemicals can disrupt the endocrine systems of vertebrate and invertebrate organisms when present at very low concentrations.

A Random Matrix Model for Color Superconductivity at Zero Chemical Potential [PDF]

Phys.Rev. D61 (2000) 076004, 1999
We discuss random matrix models for the spontaneous breaking of both chiral and color symmetries at zero chemical potential and finite temperature. Exploring different Lorentz and gauge symmetric color structures of the random matrix interactions, we find that spontaneous chiral symmetry breaking is always thermodynamically preferred over diquark ...

Excitation-Emission Matrix Spectroscopy for Analysis of Chemical Composition of Combustion Generated Particulate Matter [PDF]

Environmental Science & Technology, 2019
Analysis of particulate matter (PM) is critical for the assessment of human exposures to potentially harmful agents, notably combustion-generated PM; specifically polycyclic aromatic hydrocarbons (PAHs) found in them and associated with carcinogenic and mutagenic effects.

New Physico-Chemical Analysis of Magnesium-Doped Hydroxyapatite in Dextran Matrix Nanocomposites [PDF]

Polymers, 2023
The new magnesium-doped hydroxyapatite in dextran matrix (10MgHApD) nanocomposites were synthesized using coprecipitation technique. A spherical morphology was observed by scanning electron microscopy (SEM). The X-ray diffraction (XRD) characterization results show hydroxyapatite hexagonal phase formation.

Diquark and Pion Condensation in Random Matrix Models for two-color QCD [PDF]

Phys.Rev. D72 (2005) 015007, 2004
We introduce a random matrix model with the symmetries of QCD with two colors at nonzero isospin and baryon chemical potentials and temperature. We analyze its phase diagram and find phases with condensation of pion and diquark states in addition to the phases with spontaneously broken chiral symmetries.

IQA analysis of the two-particle density matrix: chemical insight and computational efficiency [PDF]

Theoretical Chemistry Accounts, 2023
AbstractThe interacting quantum atoms (IQA) method offers a rigorous and minimal route to calculate atomic electron correlation energies from the two-particle density matrix (2PDM). The price paid is that this method is very time-consuming. However, employing CCSD and CCSD(T), we explore several approaches to speed up such calculations.

A network dynamics approach to chemical reaction networks [PDF]

arXiv, 2015
A crisp survey is given of chemical reaction networks from the perspective of general nonlinear network dynamics, in particular of consensus dynamics. It is shown how by starting from the complex-balanced assumption the reaction dynamics governed by mass action kinetics can be rewritten into a form which allows for a very simple derivation of a number ...
