Adsorption of benzene, phenol, propane and carbonic acid molecules on oxidized Al(111) and alpha-Al2O3(0001) surfaces: A first-principles study [PDF]

J. Phys.: Condens. Matter 21 (2009) 225001, 2009
We present the results of ab initio calculations describing the adsorption of certain small organic molecules on clean and oxidized Al(111) surfaces as well as on the alpha-Al2O3(0001) surface. Our results show that adsorption of benzene on the clean and oxidized Al(111) surfaces is generally weak, the adsorption energy being at most around -0.5 eV per

Phenol-Explorer: an online comprehensive database on polyphenol contents in foods

Database J. Biol. Databases Curation, 2010
A number of databases on the plant metabolome describe the chemistry and biosynthesis of plant chemicals. However, no such database is specifically focused on foods and more precisely on polyphenols, one of the major classes of phytochemicals.

Olive oil by-product as functional ingredient in bakery products [PDF]

Food Research International, 131, 108940 (2020), 2020
By-products represent a major disposal problem for the food industry, but they are also promising sources of bioactive compounds. Olive pomace, one of the main by-products of olive oil production, is a potential low-cost, phenol-rich ingredient for the formulation of functional food.

Particle size effect of ZrO2 supports on catalytic liquid-phase oxidation of phenol over Pt/CeO2-ZrO2-Bi2O3/ZrO2 catalysts

Journal of Asian Ceramic Societies, 2020
The size effect of the ZrO2 support on the catalytic activity for the liquid-phase oxidation of phenol was demonstrated over Pt/CeO2-ZrO2-Bi2O3/ZrO2-X catalysts. Here, we selected six types of size-controlled ZrO2-X (X: A–F) (ZrO2-A: 35 nm, ZrO2-B: 22 nm,

Regioselective Monobromination of Phenols with KBr and ZnAl–BrO₃⁻–Layered Double Hydroxides

Molecules, 2020
The regioselective mono-bromination of phenols has been successfully developed with KBr and ZnAl−BrO3−−layered double hydroxides (abbreviated as ZnAl−BrO3−−LDHs) as brominating reagents. The para site is much favorable

Formulation of Laccase Nanobiocatalysts Based on Ionic and Covalent Interactions for the Enhanced Oxidation of Phenolic Compounds

Applied Sciences, 2017
Oxidative biocatalysis by laccase arises as a promising alternative in the development of advanced oxidation processes for the removal of xenobiotics. The aim of this work is to develop various types of nanobiocatalysts based on laccase immobilized on ...

The solution supramolecular structure of α2 → 8 polysialic acid suggests a structural cause for its low immunogenicity

FEBS Letters, EarlyView.
α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

Phenol in Herpes [PDF]

JAMA: The Journal of the American Medical Association, 1910
To the Editor:— For the past four years I have treated herpes with an application of a 95 per cent, solution of phenol. As soon as the skin begins to turn white I neutralize the phenol effect with alcohol. In many cases one application suffices; in no case is it necessary to make more than three applications.
