ChemFoodChem, EarlyView.This work presents a pH‐responsive ON–OFF fluorescent system based on a novel pyranoflavylium dye functionalized with a boronic acid receptor. The receptor exhibits a markedly higher affinity for the catechol‐containing polyphenol (+)‐catechin than for conventional diol‐rich molecules such as glucose and lactic acid.

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications
Environmental Progress &Sustainable Energy, EarlyView.Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Food Chemistry International, EarlyView.Boiling retained the nutrients and polyphenol compounds in Plectranthus esculentus tubers better than frying or roasting. A bioavailability study showed that the phytates and oxalates in the tuber may not affect the bioavailabilities of calcium, zinc, or iron in Plectranthus esculentus tubers when eaten.
