Tannin-Based Nanoscale Carbon Spherogels as Electrodes for Electrochemical Applications

open access: yes, 2021
A promising route to monolithic, hollow sphere carbon assemblies based on sustainable precursors with a tailored nanostructure is presented. These carbon assemblies, recently termed carbon spherogels, are generated via a polystyrene sphere template-based

Study of FTIR spectroscopy combined with Chemometrics in the characterization of vegetable tannin from Ceriops decandra [PDF]

open access: yes, 2022
The functionality and widespread application of tannins mainly depend upon their chemical structure. Successful characterization of tannin mainly results in whether it is hydrolysable or condensed.

Reactivity of Larch and Valonia Tannins in Synthesis of Tannin-Formaldehyde Resins

open access: yesBioResources, 2016
Tannin-formaldehyde resins (TFR) were prepared by copolycondensation of tannins (larch tannin or valonia tannin) and formaldehyde. The performances of TFR and the free formaldehyde residue in the system during the course of reaction were tested. Chemical

Are giraffes pollinators or flower predators of Acacia nigrescens in Kruger National Park, South Africa? [PDF]

open access: yes, 2006
We examined the relationship between giraffes (Giraffa camelopardalis) and Acacia nigrescens in Kruger National Park, South Africa, to determine whether these tall ungulates may be providing a pollination service for the trees, or are simply flower ...

THE EFFECT OF N-NH3 INCLUSION ON THE DEGRADATION OF TANNIN OF SORGHUM GRAIN BY RUMEN MICROBES [PDF]

open access: yes, 2010
Two experiments were conducted to study the effect of N-NH3 inclusion in the rumen liquor on the degradation of tannin of whole sorghum grain. The first experiment was carried out to determine the effect of N-NH3 inclusion doses in the rumen liquor on ...

Salivary proline-rich protein may reduce tannin-iron chelation: a systematic narrative review

open access: yesNutrition & Metabolism, 2017
Background Tannins are often cited for antinutritional effects, including chelation of non-heme iron. Despite this, studies exploring non-heme iron bioavailability inhibition with long-term consumption have reported mixed results.
