Earthquakes Trigger Rapid Flash Boiling Front at Optimal Geologic Conditions

Geophysical Research Letters, Volume 51, Issue 16, 28 August 2024.
Abstract The interplay between seismic activity and fluid flow is essential during the evolution of hydrothermal systems. Although earthquakes can trigger transient fluid flow and phase changes in dilational jogs, the temporal scale and the geologic conditions that enhance such process are poorly quantified.

Solving the Bilevel Facility Location Problem under Preferences by a Stackelberg‐Evolutionary Algorithm

Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014
This research highlights the use of game theory to solve the classical problem of the uncapacitated facility location optimization model with customer order preferences through a bilevel approach. The bilevel model provided herein consists of the classical facility location problem and an optimization of the customer preferences, which are the upper ...

Low Temperature Synthesis of Hexagonal Bi2Te3 Nanoplates Using an Open Reactor and Its Effect on Their Physicochemical Properties

Journal of Nanotechnology, Volume 2024, Issue 1, 2024.
This report presents the physicochemical properties of hexagonal Bi2Te3 nanoplates chemically prepared in an open reactor at a lower temperature (140°C) than those reported for controlled condition techniques. The samples were drop‐cast on glass and FTO substrates for subsequent structural, chemical, and thermoelectric analyses. The electron microscopy

US Natural Gas Market Classification Using Pooled Regression

Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014
Natural gas marketing has considerably evolved since the early 1990s, when a set of liberalizing rules were passed in both the United States and the European Union that eliminated state‐driven regulations in favor of open energy markets. These new rules changed many things in the business of energetics, and therefore new research opportunities arose ...

Nonlinear Optical Properties of a MMA‐Silica Nanohybrid Material Doped with Rhodamine 6G

Journal of Nanomaterials, Volume 2013, Issue 1, 2013., 2013
A novel nanohybrid material based on MMA‐Silica has been synthesized with an organic dye dopant (R6G) to tailor the optical properties. This novel material can be used on several devices such as active laser media for an organic solid state laser, OLEDs, or as a characterization media for new organic dye molecules.
