Turmeric and RGB analysis: A low-cost experiment for teaching acid-base equilibria at home
(American Chemical Society, 2021-01)
An experimental approach to chemistry is a more meaningful way to learn than the use of textbooks alone. Working in the laboratory helps students understand basic concepts through their active engagement. Here, we present ...
Nitrogen and potassium fertilization affect apple fruit quality in southern Brazil
(TAYLOR & FRANCIS INC, 2008)
Nitrogen (N) and potassium (K) are usually found in higher concentrations than other macronutrients in apple (Malus x domestica Borkh) fruits and are most frequently associated with changes in fruit quality. The aim of ...

Binding of fluorescent dansyl amino acids in albumin: When access to the protein cavity is more important than the strength of binding
(2021-04-01)
Human serum albumin (HSA) is the primary drug carrier protein in the blood plasma. To perform this task, it has two cavities (sites I and II) where the pharmaceutical drugs can be bound. Dansyl amino acids are fluorescent ...
Coil to extended coil transition in polygalacturonic acid: Conductometric titration and monte carlo simulations
(2000-12-28)
The conformational transition from coil to extended coil for polygalacturonic acid has been studied by conductometric titrations and Monte Carlo simulations. The results of conductometric titrations at different polymer ...

A new approach to the mechanism for the acetalization of benzaldehyde over MOF catalysts
(Royal Society of Chemistry, 2020-09-21)
The benzaldehyde acetalization reaction catalyzed by UiO-66, and its fluorinated analog UiO-66F, was carried out in a batch-type reactor at room temperature and atmospheric pressure, and the full kinetic study was performed ...
