Geometric-algebraic approach to aqueous solutions of diprotic acids and its buffer mixtures [PDF]
arXiv, 2023 A closed-form analytical expression for $\ce{[H3O+]}$ has been obtained for aqueous solutions of diprotic acids and its soluble salts. This formula allows to calculate the pH of aqueous solutions of diprotic acids, their buffer solutions, and the titrations of these two by a strong base, from the values of p$K_1$, p$K_2$, and the effective ...

Carbon Doping of MgB2 by Toluene and Malic-Acid-in-Toluene [PDF]
, 2010 The decomposition of malic acid in the presence of Mg and B was studied using Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) which revealed that malic acid reacted with Mg but not B. Also, the addition of toluene to dissolve malic acid followed by subsequent drying resulted in no reaction with Mg, indicating that the malic

Small Methods, EarlyView.A novel approach is developed to pancreatic cancer screening by targeting the cyclophili‐B (CypB)protein using a molecularly imprinted polymer with the electrode material containing Pt single‐atom‐doped/SeS2‐Ti3CNTx MXene. The quantification of CypB in pancreatic cancer tissues provide an insight into the association of CypB with pancreatic cancer ...

A search for mid-IR bands of amino acids in the Perseus Molecular Cloud [PDF]
arXiv, 2021 Amino acids are building-blocks of proteins, basic constituents of all organisms and essential to life on Earth. They are present in carbonaceous chondrite meteorites and comets, but their origin is still unknown. Formation of amino acids in the interstellar medium is posible via specific gas-phase reactions in dark clouds, however sensitive ...
