Cellulose acetate (CA) is one of the most important cellulose plastics that has demonstrated extensive applications in many areas. In search of a more sustainable and efficient way to prepare CA, we synthesized a novel ionic liquid, [DBUC]Cl, based on the commonly used catalyst DBU (1,8-diazabicyclo[5.4.

Article Synopsis
- - Cellulose is an eco-friendly raw material, and this study focuses on developing effective solvents to enhance its utilization, specifically through ten synthesized superbase amino acid ionic liquids (SAAILs) using two different diazabicyclo compounds and various amino acid anions.
- - The SAAILs' ability to dissolve cellulose is linked to their chemical properties, particularly the strength of hydrogen bonds formed between the solvents and cellulose's hydroxyl groups.
- - Among the SAAILs tested, those with DBN or DBU and proline or aspartic acid anions demonstrated excellent properties for making regenerated cellulose films, notably achieving high tensile strength and good transparency, suggesting potential for sustainable cellulose processing without toxic materials.
Article Synopsis
- A study on new stilbene-based peptoid mimics was conducted to find effective biological agents against drug-resistant citrus pathogenic bacteria.
- The peptoid mimics 9a and 9b displayed strong antibacterial activity, outperforming traditional copper-based biocides in terms of effectiveness at lower concentrations.
- These peptoids work by disrupting bacterial membranes, demonstrating potential as a new type of bactericide for protecting citrus plants from disease.
The increasing drug resistance of phytopathogenic bacteria to conventional bactericides has driven the necessity for exploring new alternatives with a lower tendency to develop bacterial resistance. Here, we report a novel cationic symmetrical peptide PVP (Ac- LI V IL -NH that enables self-assembly to form nanoparticles with excellent thermal stability. An in vitro assay showed that PVP nanoparticles exhibited excellent antibacterial activity against Xanthomonas axonopodis pv citri with a MIC value of 20 μM.
