Shape transition in light Pt isotopes: magnetic moments and electric quadrupole moment ratios for $^{185,187,189}$Pt

, 1988
Nuclear orientation and nuclear magnetic resonance experiments were performed on185, 187, 189Pt isotopes oriented in Fe and single crystal Zn at temperatures down to about 6 mK. The hyperfine splitting frequencies of185Pt and187Pt in iron were determined

The nuclear-quadrupole-induced dipole moment of HD [PDF]

, 1988
We calculate in a simple MO way the dipole moment induced in HD by the nuclear quadrupole of the deuteron, as a function of the internuclear separation. We find a reversal of the direction of the dipole with increasing internuclear separation, for which ...

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Calculation Energy Levels, B(E2), Electric Quadrupole Moment and (P.E.S.) of the Even-Even 156,158Dy Isotopes Using IBA-1 [PDF]

, 2014
Nuclear structure of 156,158Dy isotopes have been studied in the frame work of the interacting boson approximation model (IBM-1). The contour plot of the potential energy surfaces, V(?,?), shows that the nucleus 156Dy is deformed and has transitional ...

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Backward Plasma Acceleration of Aluminum, Copper, Silver, and Tantalum Ions From 1010 up to 1015 W/cm2 Pulse Laser Intensity

Contributions to Plasma Physics, EarlyView.
ABSTRACT Measurements of ion acceleration in laser‐generated plasma obtained at intensities from 1010 up to 1015 W/cm2 using IR laser ablation of aluminum, copper, silver, and tantalum in high vacuum are presented. At low intensity, data were acquired from the MIFT Department of Messina University (Italy) using a Q‐switched Nd:YAG laser operating at ...

Quadrupole moment and thermopolarization effect [PDF]

We discuss the polarization responses in insulators in relation to the quadrupole moment. The quadrupole moment is defined as the response of the free energy to the gradient of the electric field, and its spatial variation results in the polarization ...

Advantages of Pulsed Laser Ion Source (LIS) at an Intensity of About 1010 W/cm2 for Heavy‐Ion Injection Into High‐Energy Accelerators

Contributions to Plasma Physics, EarlyView.
ABSTRACT At the Laser Plasma Physics laboratories of the University of Messina, an experimental platform for generating and accelerating low‐energy ions (keV) using pulsed lasers and for their potential applications has been put into operation. A Q‐switched Nd:YAG laser produces the beam for the system, operating at 1064 nm.

Measuring Temporal Variations of Nucleotide Pools in Microbial Granular Biofilm

Helvetica Chimica Acta, EarlyView.
The developed metabolomics workflow enables quantification of energy nucleotides in complex microbial biofilms. The method provides a foundation for investigating rapid metabolic responses to dynamic environmental conditions. ABSTRACT Microbial communities often face environmental fluctuations that occur on timescales much shorter than their growth ...
