ChemPlusChem, EarlyView.Gold nanoparticles (AuNPs) are widely used in biomedicine, electronics, catalysis, and environmental science. Conventional synthesis relies on harsh chemicals, driving interest in eco‐friendly methods using plants, bacteria, fungi, and algae. Biomolecules like polyphenols, proteins, and fatty acids aid nanoparticle synthesis under mild conditions. This

ChemSusChem, EarlyView.Redox mediators are essential to promote the electrogenic activity of cyanobacteria in biophotovoltaics. In this work, we systematically evaluates three representative mediators about their influence on the cyanobacterial growth, photosynthetic efficiency, and electrogenic activity. The results reveal distinct impacts of different mediators, despite of

Evolutionary Patterns of Thylakoid Architecture in Cyanobacteria [PDF]
Frontiers in Microbiology, 2019 While photosynthetic processes have become increasingly understood in cyanobacterial model strains, differences in the spatial distribution of thylakoid membranes among various lineages have been largely unexplored. Cyanobacterial cells exhibit an intriguing diversity in thylakoid arrangements, ranging from simple parietal to radial, coiled, parallel ...

Engineered Living Energy Materials
Interdisciplinary Materials, EarlyView.Engineered living energy materials (ELEMs) are nascent research frontier for enabling sustainable energy conversion and storage. These materials exhibit unique characteristics such as self‐regeneration, biodegradability, environmental response, and evolutionary adaptability. This paper overviews different energy conversion bio‐modules, summarizes their

Chloroplast Ca2+ Fluxes into and across Thylakoids Revealed by Thylakoid-Targeted Aequorin Probes [PDF]
Plant Physiology, 2018 Chloroplasts require a fine-tuned control of their internal Ca2+ concentration, which is crucial for many aspects of photosynthesis and for other chloroplast-localized processes. Increasing evidence suggests that calcium regulation within chloroplasts also may influence Ca2+ signaling pathways in the cytosol.
