Highly Efficient and Durable Ammonia Electrolysis Cell Using Zirfon Separator.

Most studies on ammonia electrolysis have focused on anion exchange membranes (AEMs), which face limitations in operating conditions, such as pH and ammonia concentration. This study introduces a novel concept of an ammonia electrolysis cell (AEC) utilizing a Zirfon separator capable of operating under high pH and ammonia concentrations. The Zirfon-based AECs achieve a peak current density of 915 mA cm, representing the highest reported value in AEC literature.

Differential Effects of the Interaction Between the Education and APOE ε4 Allele on Amyloid-beta Retention and Memory Performances in Cognitively Normal Older Adults and Alzheimer's Disease Patients.

Background: Despite the effect of education and APOE ε4 allele on amyloid-beta (Aβ) retention and memory, previous studies have not dealt with an interaction between two factors on Aβ deposition and memory function in the course of Alzheimer's disease (AD).

Objective: To evaluate education by APOE ε4 allele interactions for Aβ retention and neuropsychological test scores in cognitively normal older adults without Aβ deposition [CN(Aβ-), n=45] and Alzheimer's disease patients with Aβ retention [AD(Aβ+), n=33].

Methods: Multiple regression analyses (adjusted for age, gender) were conducted to examine the effects of education, APOE ε4 allele, and the interaction between the two factors on global, regional Aβ load quantified using [18F]flutemetamol standardized uptake value ratio with the pons as a reference region, and on neuropsychological test scores in each group.
