Linear-Organic-Ions In Situ-Intercalated MoS for Unveiling Capacitive Energy Storage Relies on the Chain Length.

Intercalating linear-organic-ions into the MoS interlayer is beneficial for optimizing electrons/ions' capacitive storage behavior. The chain length, as an important parameter of linear organic ions, can lead to differences in the dispersion, polarity, critical micelle concentration of organic ions, and steric hindrance to the growth of MoS nanosheets. Up until now, the relationship between chain length, synthesis of intercalated-MoS, and capacitive energy storage has not been unveiled.

The Physiological Functionality of PGR5/PGRL1-Dependent Cyclic Electron Transport in Sustaining Photosynthesis.

The cyclic electron transport (CET), after the linear electron transport (LET), is another important electron transport pathway during the light reactions of photosynthesis. The proton gradient regulation 5 (PGR5)/PRG5-like photosynthetic phenotype 1 (PGRL1) and the NADH dehydrogenase-like complex pathways are linked to the CET. Recently, the regulation of CET around photosystem I (PSI) has been recognized as crucial for photosynthesis and plant growth.

Chloroplast NAD(P)H dehydrogenase (NDH) complex, a multiple-subunit complex in the thylakoid membranes mediating cyclic electron transport, is one of the most important alternative electron transport pathways. It was identified to be essential for plant growth and development during stress periods in recent years. The NDH-mediated cyclic electron transport can restore the over-reduction in stroma, maintaining the balance of the redox system in the electron transfer chain and providing the extra ATP needed for the other biochemical reactions.

Microtopography affects hydrological processes and forms different microhabitats. Our previous study uncovered that riparian zone microtopography created various microhabitats with different soil environments and runoff-infiltration patterns. However, how riparian microtopography and microtopography within the water area (waterfall and tributary) affects downstream water quality remains unclear.

Protective Effects of Incretin Against Age-Related Diseases.

Incretin contains two peptides named glucagon-like peptide-1(GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Drug therapy using incretin has become a new strategy for diabetic treatments due to its significant effects on improving insulin receptors and promoting insulinotropic secretion. Considering the fact that diabetes millitus is a key risk factor for almost all age-related diseases, the extensive protective roles of incretin in chronic diseases have received great attention.
