Energy Science &Engineering, EarlyView.This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

Technical Efficiency in Portuguese Dairy Farms [PDF]
This paper addresses issues related to efficiency measurement from an empirical point of view. A stochastic frontier production model using a translog is estimated for a group of Portuguese dairy farms. Farm level survey data for the period 1988 -2005 is

Energy Science &Engineering, EarlyView.ABSTRACT Traditional air conditioners suffer from low energy efficiency and exacerbate grid peak loads. While ice storage offers energy‐saving potential, the systematic regulation of ice packing fraction (IPF) on cooling consumption and its synergy with dynamic carbon emissions remains unexplored.
