Sodium manganese hexacyanoferrate, also called Prussian white (PW), has attracted much attention as a promising cathode material for Na-ion batteries due to its high-voltage platform and inexpensive elemental composition. However, their parasitic vacancies and water molecules often deteriorate the electrochemical performance. Proper regulation of such defects in scale-up preparation is still a challenge. In this work, PW was prepared via aqueous precipitation assisted by manganese oxalate in a 10 L reactor. High-quality NaMn[Fe(CN)]□·1.97 HO was obtained and exhibited a specific capacity of 148 mAh g. The phase transition from monoclinic to rhombohedral during long-term cycling for such an ultra-Na-rich cathode has been first reported. In addition, the vacuum drying temperature was further discussed, and 150 °C is more suitable for achieving the balance between dehydration and electrical properties.

In this study, five strains previously isolated from black liquor (BL) and vinasse (V) were tested to assess the most promising regarding its capacity of biosurfactant production. For that, four factorial designs of two factors at two levels (2) were run for each strain. Selected factors were the production time and the composition media, while the surface tension reduction and optical density were the responses variables.

Article Synopsis
- Researchers developed a new, cost-effective micromixing technique for creating liposome nanoformulations, comparing it to the conventional thin-film hydration (TFH) method.
- The study used simulations and experimental design to determine optimal conditions for producing anionic liposomes, with both methods resulting in similar properties such as size, encapsulation efficiency, and stability.
- The micromixing method offers a one-step production process that is highly controllable, reproducible, and compatible with various solvents, making it a versatile alternative for nanoliposome manufacturing.

Spray drying presents numerous advantages over other drying technologies, particularly for inhaled biologics because of the fine-tuned particle attributes requirements. To fully leverage these benefits, it is crucial to address several process challenges and considerations throughout the end-to-end spray-drying process, including stages prior to, during, and post- drying. This review provides a detailed overview of the challenges associated with spray-drying of biologics along with the aspects of protein degradation.

8-(Azidomethyl)-1-naphthoic acid was elaborately prepared, and its coupling with amines provided the corresponding 8-(azidomethyl)-1-naphthamides. The Staudinger reactions of 8-(azidomethyl)-1-naphthamides with phosphine produced iminophosphoranes, and easy intramolecular cyclization of the iminophosphoranes afforded 2,3-dihydro-1-benzo[]isoquinolin-1-one leaving amines with almost quantitative conversion rates for the ipsilateral effect of 1,8-substituents on naphthalene. The protocol exhibits some advantages, including a readily available protecting group, cleavages of amides in almost quantitative conversion rates, an aqueous medium, reactions at room temperature, a broad substrate scope, wide functional group tolerance, and suitable scale-up reactions.
