Electrochemical and morphological characterization of porous alumina formed by galvanostatic anodizing in etidronic acid [PDF]
Electrochimica Acta, 2019 Abstract Electrochemical and morphological characterization of the porous alumina formed by galvanostatic anodizing in etidronic acid under various operating conditions was performed. High-purity aluminum plates were anodized in 0.03–3 M etidronic acid solutions at 273–333 K and 0.25–500 Am−2 for up to 24 h.

Ab initio Investigation of Adsorption Characteristics of Bisphosphonates on Hydroxyapatite (001) Surface [PDF]
arXiv, 2016 The structures of some bisphosphonates (clodronate, etidronate, pamidronate, alendronate, risedronate, zoledronate, minodronate) were obtained and analyzed, and their adsorption energies onto hydroxyapatite (001) surface were compared to find out ranking order of binding affinity, which shows that the adsorption energy is the largest for pamidronate ...

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 ...

Acid zeta function and ajoint acid zeta function [PDF]
arXiv, 2010 In this paper we set up the theory of acid zeta function and ajoint acid zeta function, based on the theory, we point out a reason to doubt the truth of the Riemann hypothesis and also as a consequence, we give out some new RH equivalences.

Dose-dependent effect of calcium and magnesium etidronate on salicylic acid absorption in the rat
Journal of Pharmacy and Pharmacology, 1985 Abstract Disodium etidronate affected salicylic acid absorption from the rat small intestine, in-situ, when instilled into a jejunal segment for different exposure times before the salicylic acid absorption was measured. At low etidronate concentrations and short exposure times, the salicylic acid absorption rate was significantly ...

Is Amino-Acid Homochirality Due To Asymmetric Photolysis In Space? [PDF]
arXiv, 1999 Amino acids occurring in proteins are, with rare exceptions, exclusively of the L-configuration. Among the many scenarios put forward to explain the origin of this chiral homogeneity (i.e., homochirality), one involves the asymmetric photolysis of amino acids present in space, triggered by circularly polarized UV radiation.

Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]
arXiv, 2006 The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each

The Factors of the Classification of Protein Amino Acids [PDF]
This paper is published in GLASNIK of Montenegrin Academy of
Science and arts, 2000, 13, pp. 173-194, 2006 In this work it is shown that three pairs of the factors appear to be the key, i.e. main factors of a natural classification of protein (canonical) amino acids within the amino acid (genetic) code. First pair: the factors of the habit of an amino acid molecule (size and polarity).

International Journal of Dentistry, 2013 This study investigated the effect of sodium hypochlorite (NaOCl), ethylenediaminetetraacetic (EDTA), etidronic (HEBP), and citric acid (CA) associated in different irrigation regimens on root dentin microhardness. Forty-five root halves of single-rooted
