Application



  • Buffer systems for environmental toxicology: A study utilized buffer concentrates within a tiered regulatory framework for aquatic risk assessment of pesticides, emphasizing the critical role of standardized buffer systems in maintaining consistent experimental conditions (Santos et al., 2024).


  • Buffer concentrate in pharmaceutical formulations: Buffer concentrates were used in the development of a prolonged permeation in situ gel for Levofloxacin HCl-Salicylic Acid, underlining the importance of buffer systems in drug release modulation and stability (Khaing et al., 2024).


  • Buffer concentrate in diagnostic assays: The formulation of lateral flow devices for the detection of urinary biomarkers in kidney health assessments incorporated buffer concentrates to ensure optimal reagent performance and reaction kinetics (D Souza et al., 2024).

Polymer solar cells are fabricated with systematic variation of the phase purity. Photovoltaic tests demonstrate that devices with ca. 10% of mixed phases outperform pure-phase devices. Photophysical studies reveal the effects of mixed phase on charge generation and recombination. These

We compare the singlet fission dynamics of five pentacene derivatives precipitated to form nanoparticles. Two nanoparticle types were distinguished by differences in their solid-state order and kinetics of triplet formation. Nanoparticles that comprise primarily weakly coupled chromophores lack the bulk
