Chlorine-free electrochemical disinfection using graphene sponge electrodes [PDF]

Chemical Engineering Journal, 2021, 132772, 2021
Graphene sponge electrodes were employed for chlorine-free inactivation of Escherichia coli from low conductivity water. The nitrogen-doped reduced graphene oxide (NRGO) sponge anode bearing more positive charge achieved complete E. coli inactivation (i.e., 5 log removal) in the anode-cathode configuration at 115 A m-2, versus 2.6 log removal using ...

Lead Perchlorate as a Neutrino Detection Medium [PDF]

Nucl.Instrum.Meth. A492 (2002) 43-48, 2002
Lead can be an ideal medium for the detection and study of neutrinos. Such a detector may be realized through the use of a lead perchlorate solution as a Cerenkov radiator. The basic physical properties of lead perchlorate solution are given and preparation of the solution for use in a Cerenkov detector is described.

Measuring Supernova Neutrino Temperatures using Lead Perchlorate [PDF]

Phys.Rev.C62:065802,2000, 2000
Neutrino interactions with lead produce neutrons in numbers that depend on neutrino energy and type. A detector based on lead perchlorate, for example, would be able to measure the energy deposited by electrons and gammas in coincidence with the number of neutrons produced.

Observing Nucleon Decay in Lead Perchlorate [PDF]

Phys.Rev. D68 (2003) 074014, 2003
Lead perchlorate, part of the OMNIS supernova neutrino detector, contains two nuclei, 208Pb and 35Cl, that might be used to study nucleon decay. Both would produce signatures that will make them especially useful for studying less-well-studied neutron decay modes, e.g., those in which only neutrinos are emitted.

Neutrino Detection using Lead Perchlorate [PDF]

Nucl.Phys.Proc.Suppl. 87 (2000) 512-513, 2000
We discuss the possibility of using lead perchlorate as a neutrino detector. The primary neutrino interactions are given along with some relevant properties of the material.

Anharmonic force fields of perchloric acid, HClO$_4$, and perchloric anhydride, Cl$_2$O$_7$. An extreme case of inner polarization [PDF]

Journal of Molecular Structure 780-781, 310-316 (2006), 2005
DFT (density functional theory) anharmonic force fields with basis sets near the Kohn-Sham limit have been obtained for perchloric acid, HClO$_4$, and perchloric anhydride, Cl$_2$O$_7$. Calculated fundamental frequencies are in very good agreement with available experimental data.

Electric field induced reversible control of visible photoluminescence from ZnO nanoparticles [PDF]

Appl. Phys. Lett. 98, 153109 (2011), 2011
Reversible control of the photoluminescence of ZnO occurring in the visible range, has been achieved by application of a few volts (< 5V) to a device consisting of nanostructured ZnO film sandwiched between Indium Tin Oxide electrode and polyethylene oxide-lithium perchlorate, a solid polymer electrolyte.

Machine Learning Directed Optimization of Classical Molecular Modeling Force Fields [PDF]

, 2021
Accurate force fields are necessary for predictive molecular simulations. However, developing force fields that accurately reproduce experimental properties is challenging. Here, we present a machine learning directed, multiobjective optimization workflow for force field parameterization that evaluates millions of prospective force field parameter sets

Heats of formation of perchloric acid, HClO$_4$, and perchloric anhydride, Cl$_2$O$_7$. Probing the limits of W1 and W2 theory [PDF]

J. Mol. Struct. (THEOCHEM) 771, 19-26 (2006), 2005
The heats of formation of HClO$_4$ and Cl$_2$O$_7$ have been determined to chemical accuracy for the first time by means of W1 and W2 theory. These molecules exhibit particularly severe degrees of inner polarization, and as such obtaining a basis-set limit SCF component to the total atomization energy becomes a challenge.

Surface tensions, surface potentials and the Hofmeister series of electrolyte solutions [PDF]

Langmuir 2010, 26(13), 10778, 2010
A theory is presented which allows us to accurately calculate the surface tensions and the surface potentials of electrolyte solutions. Both the ionic hydration and the polarizability are taken into account. We find a good correlation between the Jones-Dole viscosity $B$-coefficient and the ionic hydration near the air-water interface.
