Experimental and Numerical Investigation of Flow Structures Around Different Binary Building Geometries
(Pleiades Publishing Ltd,, 31.03.2022)
The separation zones resulting from the wind interaction with a building and its
immediate surroundings are of great importance for determination of multiple vortex systems
interacting with the building and for consideration ...
OPTIMIZATION OF POLYPHENOL EXTRACTION FROM CHESTNUT WASTE PRETREATED BY OHMIC HEATING USING BOX-BEHNKEN DESIGN
(2022)
Chestnut processing produces a large amount of waste peels, which contain considerable polyphenols. The aim of this research was to optimize the extraction method for phenolic compounds from industrial chestnut peel ...
Valorization of agricultural by-product: Optimization of alcohol-based extraction of polyphenols from chestnut peel using Box-Behnken Design
(February 2)
In the present work, solvent concentration, extraction time, and solid to solvent (S/S) ratio were evaluated in order to recover the majority of polyphenols from chestnut peel waste using ethanol and methanol. Extraction ...
Application of a new dithizone grafted polymeric adsorbent for solid phase microextraction of manganese and copper prior to FAAS in fortified vegetables and barbecue samples
(2022)
A new potential solid phase material called as dithizone@PAA was synthesized for first times, characterized and utilized as
an easy versatile polymeric sorbent for the shake-assisted dispersive solid-phase micro-extraction ...
