Polarization Potential Has No Effect on Maximum Current Density Produced by Halotolerant Bioanodes

Energies, 2018
Halotolerant bioanodes are considered an attractive alternative in microbial electrochemical systems, as they can operate under higher conductive electrolytes, in comparison with traditional wastewater and freshwater bioanodes.

A Comprehensive Multistage Average Controller for Trajectory Tracking in Solar‐Powered Mobile Robots: Analysis of Actuator‐Driver and Power Stage Integration

International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 224-246, June 2026.
ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

Ocean Wave Modulation of Offshore Wind Turbine Loads and Wake

Wind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT This study examines how wave‐induced modulation affects the operational performance and structural dynamics of fixed‐bottom offshore wind turbines operating under a neutral atmospheric boundary layer profile. To capture these effects accurately while maintaining computational efficiency, unsteady RANS modelling techniques are employed.

The Power of Professional Expertise: Unravelling the Boardroom Diversity Puzzle Through a Machine Learning Approach

Accounting &Finance, Volume 66, Issue 2, Page 1571-1593, June 2026.
ABSTRACT This study examines how board expertise diversity influences firm performance using a novel machine learning approach to classify directors' professional backgrounds. Drawing on data from Spanish listed firms, we develop multidimensional expertise profiles that capture multiple skills held by each director.

Ni Microspheres as Electrocatalysts for Ethanol Oxidation in an Alkaline Medium

International Journal of Electrochemical Science, 2018
We report the synthesis of nickel microspheres and their structural and electrochemical characterization. The materials were prepared by the microemulsion technique from NiSO4∙6H2O and NaOH, and using NaH2PO2∙H2O as a reducing agent.

Political Cycles, Electricity Policy, and Mexico's Economy

Latin American Policy, Volume 17, Issue 2, June 2026.
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

Characterization of Composite Mesoporous Carbon/Conducting Polymer Electrodes Prepared by Chemical Oxidation of Gas-Phase Absorbed Monomer for Electrochemical Capacitors

International Journal of Electrochemical Science, 2011
Mesoporous carbon/conducting polymer composites have been synthesized by adsorption of different monomers (aniline, pyrrole, thiophene and 3-methyltiophene) in the gas phase onto the carbon surface, followed by oxidative chemical polymerization.
