应用



  • 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).

Tetrahydrofuran-containing macrolides: a fascinating gift from the deep sea.
Adriana Lorente et al.
Chemical reviews, 113(7), 4567-4610 (2013-03-20)
Ryan D Pensack et al.
Journal of the American Chemical Society, 137(21), 6790-6803 (2015-05-07)
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
Luca Chiari et al.
The Journal of chemical physics, 138(7), 074301-074301 (2013-03-01)
We present total, elastic, and inelastic cross sections for positron and electron scattering from tetrahydrofuran (THF) in the energy range between 1 and 5000 eV. Total cross sections (TCS), positronium formation cross sections, the summed inelastic integral cross sections (ICS)
P T Clayton et al.
The Journal of clinical investigation, 79(4), 1031-1038 (1987-04-01)
Urinary bile acids from a 3-mo-old boy with cholestatic jaundice were analyzed by ion exchange chromatography and gas chromatography-mass spectrometry (GC-MS). This suggested the presence of labile sulfated cholenoic acids with an allylic hydroxyl group, a conclusion supported by analysis
Han Yan et al.
Advanced materials (Deerfield Beach, Fla.), 27(23), 3484-3491 (2015-05-06)
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
