What does a verbal working memory task measure? The process-specific and age-dependent nature of attentional demands in verbal working memory tasks.

Most models of verbal working memory (WM) consider attention as an important determinant of WM. The detailed nature of attentional processes and the different dimensions of verbal WM they support remains, however, poorly investigated. The present study distinguished between attentional capacity (scope of attention) and attentional control (control of attention) and examined their respective role for two fundamental dimensions of verbal WM: the retention of item versus serial order information and the simple versus complex nature of WM tasks.

This study aimed to elucidate the pathways through which covalent and non-covalent interactions between deamidated gliadin (DG) and tannic acid (TA) on influence the stability of Pickering emulsions. The interactions induced protein unfolding, as evidenced by increased ultraviolet absorption and a red shift in fluorescence emission. DG-TA composite nanoparticles effectively stabilized high internal phase emulsions, whereas DG nanoparticles alone did not.

The present work reports a clear and improved hydrothermal methodology for the synthesis of MoSe nanoflowers (MNFs) at 210 °C. To observe the effect of temperature on the fascinating properties, the process temperature was modified by ±10 °C. The as-prepared MNFs were found to consist of 2D nanosheets, which assembled into a 3D flower-like hierarchical morphology van der Waals forces.

The advancement of rapid-response grid energy storage systems and the widespread adoption of electric vehicles are significantly hindered by the charging times and energy densities associated with current lithium-ion battery technology. In state-of-the-art lithium-ion batteries, graphite is employed as the standard negative electrode material. However, graphite suffers from polarization and deteriorating side-reactions at the high currents needed for fast charging.

Aqueous zinc batteries offer promising prospects for large-scale energy storage, yet their application is limited by undesired side reactions at the electrode/electrolyte interface. Here, we report a universal approach for the building of an electrode/electrolyte interphase (EEI) layer on both the cathode and the anode through the self-polymerization of electrolyte additives. In an exemplified Zn||VO·nHO cell, we reveal that the glutamate additive undergoes radical-initiated electro-polymerization on the cathode and polycondensation on the anode, yielding polyglutamic acid-dominated EEI layers on both electrodes.
