Article Synopsis
- Ferrocene is an important electron donor, and understanding its excited states is crucial for creating effective donor-acceptor (D-A) molecules with stable charge transfer states.
- Research using femtosecond optical transient absorption spectroscopy has identified two electronic excited states in a bimetallic D-A compound, with lifetimes of 30 ps and 500 ps, revealing a high-spin (d-d) state that is typically underrepresented in discussions about ferrocene.
- X-ray transient absorption spectroscopy further confirmed the high-spin character of the state with a 500 ps lifetime, indicating notable structural changes that are significant for improving the design of ferrocene-based materials in photocatalysis and photovoltaics.
Methanogenic archaea, which are integral to global carbon and nitrogen cycling, currently face challenges in genetic manipulation due to unique physiology and limited genetic tools. This review provides a survey of current and past developments in the genetic engineering of methanogens, including selection and counterselection markers, reporter systems, shuttle vectors, mutagenesis methods, markerless genetic exchange, and gene expression control. This review discusses genetic tools and emphasizes challenges tied to tool scarcity for specific methanogenic species.

However, the mechanism by which light enables and enhances the reactivity of these complexes often remains elusive. Although optical techniques have been widely used to study the ground and excited states of photocatalysts, they lack the specificity to interrogate the electronic and structural changes at specific atoms.
