Abstract
Comprehensive assessment of polymer-colloid systems based on cationic surfactant with triallyl head group (TAS-16) in the presence of synthetic polyelectrolytes (polyacrylic acid (PAA), sodium polyacrylate (SPA), and sodium polystyrene sulfonate (PSS)) has been carried out. The addition of a weak polyelectrolyte PAA reduces the critical micelle concentration (CMC) of the amphiphile up to 50 times, while the strong polyelectrolytes PSS and SPA, have a minor effect on the aggregation thresholds of the surfactant. Transmission electron microscopy shows the formation of mixed spherical aggregates grouped together like a pearl necklace. The mixed compositions exhibit antitumor activity against the HuTu 80 cell line and lower cytotoxicity toward normal Chang liver cells. The polymers do not induce hemolysis and hemagglutination, while TAS-16 exhibits moderate hemolytic activity in single system and in the composition. The polymer-colloid complexes containing strong polyelectrolyte SPA were more effective as nanocontainers to enhance the solubility of the hydrophobic antibiotic Amphotericin B.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
