Colloidal transport of heavy metals in low‐advective‐velocity environmental systems: Reactive transport model on biogeochemical and hydrodynamic impacts

open access: yesVadose Zone Journal, Volume 22, Issue 1, January/February 2023., 2023
Abstract In this study, the impact of colloid facilitated transport of heavy metals on the overall biogeochemical processes is demonstrated in example Lake Coeurd'Alene sediments. Release and transport of heavy metals (Pb and Zn) on initially sorbed colloidal Fe (hydr)oxide minerals are compared with immobile surfaces under various advective flow ...

Valorization of Apple Pomace: Production of Phloretin Using a Bacterial Cellulose‐Immobilized β‐Glycosidase

open access: yesChemSusChem, EarlyView.
This study presents a whole valorization of apple processing waste: phloretin is efficiently produced from phloridzin (abundantly found in apple residues), using a β‐glycosidase immobilized on bacterial cellulose in a biphasic system. Notably, bacterial cellulose is derived from fermentation of apple pomace sugars, making both the enzyme carrier and ...

Tricyanated Ferrocenes; Isolation, structure, electrochemistry and DFT calculations

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 649, Issue 1, January 2, 2023., 2023
Abstract 1,2,3‐ Tricyanoferrocene and 1,3‐dibromo‐2,4,5‐tricyanoferrocene have been synthesized via metallation and usage of dimethylmalononitrile (DMMN) as cyanating agent. They are the first compounds where three nitrile functions could be introduced into the ferrocene sceleton.

Protein‐binding approaches for improving bioaccessibility and bioavailability of anthocyanins

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 22, Issue 1, Page 333-354, January 2023., 2023
Abstract Color is an important characteristic of food. Over the last 15 years, more attention has been paid to natural colorants because of the rising demand for clean‐label food products. Anthocyanins, which are a group of phytochemicals responsible for the purple, blue or red hues of many plants, offer a market advantage.

Mercaptans in malodorants break disulfide bridges in human serum albumin and form adducts suitable as biomarkers of exposure in vitro

open access: yesDrug Testing and Analysis, EarlyView.
Disulfide adducts of mercaptans with cysteine residues in human serum albumin were detected as tripeptides and dipeptides after proteolysis with proteinase K. All peptide adducts were detected simultaneously with a mass spectrometry‐based method working in the scheduled multiple reaction monitoring (sMRM) mode.
