A convenient method to prepare a series of benzodithiine derivatives was developed, via the synthesis of cyclic disulfide building blocks containing an amino-group linker. Some of the novel cyclic disulfide compounds are shown to modulate the activity of the redox-enzyme glutathione reductase.

Previous researchers have conducted extensive investigations on the impact of various working conditions on fatigue damage. However, further research is still needed to understand the underlying mechanism of how the excitation frequency of cyclic loading affects the fatigue life. This article systematically discloses the phononic origin of atomic scale fatigue resonance, focusing on single-layer molybdenum disulfide (SL MoS) as a prototypical material.

Disulfide bonds are ubiquitous molecular motifs that influence the tertiary structure and biological functions of many proteins. Yet, it is well known that the disulfide bond is photolabile when exposed to ultraviolet C (UVC) radiation. The deep-UV-induced S─S bond fragmentation kinetics on very fast timescales are especially pivotal to fully understand the photostability and photodamage repair mechanisms in proteins.

Increasing attention to sustainability and cost-effectiveness in energy storage sector has catalyzed the rise of rechargeable Zinc-ion batteries (ZIBs). However, finding replacement for limited cycle-life Zn-anode is a major challenge. Molybdenum disulfide (MoS), an insertion-type 2D layered material, has shown promising characteristics as a ZIB anode.

Silver nanowire (Ag NW)-based elastic conductors have been considered a promising candidate for key stretchable electrodes in wearable devices. However, the weak interface interaction of Ag NWs and elastic substrates leads to poor durability of electronic devices. For everyday usage, an additional self-healing ability is required to resist scratching and damage.

FOXM1 is the "Achilles' heel" of cancers and hence the potential therapeutic target for anticancer drug discovery. In this work, we selected high affinity peptides against the protein of human DNA binding domain of FOXM1 (FOXM1-DBD) from the disulfide-constrained, phage displayed random cyclic heptapeptide library Ph.D.
