- This report provides a snapshot of emerging photovoltaic (PV) technologies. It consists of concise contributions from experts in a wide range of fields including silicon, thin film, III-V, perovskite, organic, and dye-sensitized PVs. Strategies for exceeding the detailed balance limit and for light managing are presented, followed by a section detailing key applications and commercialization pathways. A section on sustainability then discusses the need for minimization of the environmental footprint in PV manufacturing and recycling. The report concludes with a perspective based on broad survey questions presented to the contributing authors regarding the needs and future evolution of PV.(c) 2023 Society of Photo-Optical Instrumentation Engineers (SPIE)

- Bacterial second messenger signaling often plays an important role in cellular physiology. In this study, we have attempted to understand how c-di-AMP synthesis and degradation are transcriptionally regulated in Mycobacterium smegmatis. We found that although a c-di-AMP synthesis gene, disA, exists in a multi-gene operon, a sub-operon promoter arrangement facilitates disA gene expression under normal conditions to maintain intracellular c-di-AMP concentration and is induced further during certain stress adaptations. Individual gene-specific promoters also play a key role under various genotoxic stress conditions to shut down c-di-AMP synthesis, which could otherwise be detrimental for cells. Further, we learned that a high c-di-AMP concentration plays a role in the autoregulation of the disA promoter to limit intracellular c-di-AMP concentration. This study was helpful to understand how c-di-AMP synthesis is regulated under normal and stress conditions linked to its physiological relevance in M. smegmatis.
