Photoacoustic imaging is an emerging modality with significant promise for biomedical applications such as neuroimaging, owing to its capability to capture large fields of view deep inside complex scattering tissue. However, widespread adoption of this technique has been hindered by a lack of suitable molecular reporters for this modality. In this work, we introduce chemigenetic labels and calcium sensors specifically tailored for photoacoustic imaging, using a combination of synthetic dyes and HaloTag-based self-labeling proteins.

Here, using a custom-designed reactor to rapidly initiate solid-state syntheses, we are able to capture the earliest stages of a reaction using X-ray scattering. For the reaction of TiO and LiCO to form spinel lithium titanate (LiTiO)─an anode material for fast-charging applications─we capture two distinct kinetic regimes, including fast initial kinetics in the first seconds-minutes of the reaction that account for significant product formation.

- Synthesis of new inorganic materials is challenging due to limited guidance on optimal solid-state procedures.
- Researchers introduced primary and secondary competition metrics to assess how likely target materials will form compared to impurities in solid-state reactions.
- They applied these metrics to analyze thousands of reactions, identifying efficient synthesis methods for barium titanate (BaTiO) that outperform traditional approaches by using unconventional precursors.
Article Synopsis
- Exploration of mechanochemical synthesis of α-NaFeO highlights a novel method that eliminates the need for high-temperature annealing typically used in other synthesis processes.
- The study found that variations in starting precursors and their mass influenced the resulting structure of NaFeO, with density functional theory indicating that the α phase is favored in oxidizing conditions.
- Annealing the as-milled α-NaFeO at 700 °C enhanced its crystallinity and electrochemical performance, suggesting a pathway for better understanding and controlling polymorphs in NaFeO.
When confronted with illness, humans and animals undergo critical changes in their behavior and physiology. New research shows how neuronal circuits detect sickness and coordinate illness-specific responses.
