Anode-free post-Li metal batteries.

Anode-free metal batteries (AFMBs) are a new architecture of battery technology that relies solely on current collectors (CCs) at the anode side, eliminating the need for traditional metal anodes. This approach can pave the way for higher energy densities, lower manufacturing costs, and lower environmental footprints associated with metal batteries. This comprehensive review provides an in-depth exploration of AFMB technology, extending its scope beyond lithium and into a broader range of metals (sodium Na, potassium K, magnesium Mg, zinc Zn and aluminum Al).

A cross-sectional study on the role of computer anxiety in students' online learning.

Introduction: Although e-learning has been incorporated in higher education system, students may undergo negative emotions like anxiety using this new mode of learning which ultimately interfere with their learning performance. Hence, the current study aimed to examine the role of computer anxiety in students' online learning.

Methods: This is a cross-sectional correlational study, in which a convenient sample of 330 students of Shiraz University of Medical Sciences participated.
