The interplay of defects and dopant ( l -Dopa) in LD@D-UiO-66 enhances proton conduction.

Titanium carbonate nanoparticles (TiCO₃ NPs) were synthesized and extensively characterized using advanced spectroscopic and microscopic techniques to confirm their crystalline structure, morphology, and stability. Biocompatibility assessments revealed minimal cytotoxicity, supporting their potential for biomedical applications. The therapeutic efficacy of TiCO₃ NPs was investigated in a diabetic mouse model, where oral administration significantly improved glycemic control, reduced fasting blood glucose levels, and enhanced insulin sensitivity compared to untreated controls. In parallel, the antibacterial potential of TiCO₃ NPs was evaluated against clinically relevant pathogens, including Enterobacter sp., and Staphylococcus aureus. These results confirm the broad-spectrum antibacterial potential of TiCO₃, highlighting their capacity to disrupt both Gram-positive and Gram-negative bacteria. Collectively, these findings establish TiCO₃ NPs as a multifunctional nanomaterial with excellent biocompatibility, effective glycemic regulation in diabetic models, and broad-spectrum antibacterial activity, positioning them as promising candidates for therapeutic and biomedical applications.

Harnessing sunlight to produce electricity is the most sustainable form of alternative energy. Apart from commercial silicon solar cells, organic solar cells (OSCs) have great potential due to their flexibility, processability and cost. To improve device performance, broadband absorption, electrical mobility and charge separation are the key components for optimization. Although discrete efforts have been dedicated to comprehending the role of different chemical structures on their power conversion efficiencies (PCE), a systematic screening of multiple structural factors on PCE has not been reported. Herein, we shortlisted rylene diimides as model acceptors in OSCs and demonstrated the role of (a) expanding the rylene core (pyromellitic to bisazulene); (b) changing the ring size (five-member and six-member) and positions (2,3- vs. 1,8/9) of the diimide; (c) changing the diimide sidechain from alkyl to aryl; and (d) twisting core-planarity of rylene (pyrene to corannulene) and the effect on their structural parameters, optical absorption spectra and electron mobilities. Moreover, the combined six-fold screening predicted the candidate with the highest electron mobility in the series. This comprehensive assessment of critical factors on OSC performance paves the way for improved design of acceptor molecules for higher PCE.
