Properties and Mechanisms of TBBPA and TBBPS Adsorption onto Various Soils in China [PDF]

open access: yesToxics
Understanding the differences in the adsorption behaviors of tetrabromobisphenol A (TBBPA) and tetrabromobisphenol S (TBBPS) on soils is critical for assessing their environmental mobility and risks. This study investigated the adsorption characteristics

Molecular structure and composition elucidation of an industrial humin and its fractions.

open access: yesGreen Chem
Humins, (side-)products of the acid-catalysed dehydration of carbohydrates, will be produced in substantial quantities with the development of industrial biorefining processes.

Spectral Predictability of Soil Organic Matter Depends on Its Humin Fraction Rather than Spectral Fusion [PDF]

open access: yesSensors
Soil organic matter (SOM) governs critical soil functions, including carbon storage, nutrient cycling, and microbial activity; yet the specific fractions responsible for its spectral predictability remain poorly understood.

Mechanistic understanding of humin formation in the conversion of glucose and fructose to 5-hydroxymethylfurfural in [BMIM]Cl ionic liquid

open access: yesRSC Advances, 2020
Humin formation is one of the key issues that hinders economical 5-HMF production from hexose sugars such as glucose and fructose. In this work, the mechanism of humin formation in glucose/fructose conversion to HMF was studied in an ionic liquid system (

Full, Reactive Solubilization of Humin Byproducts by Alkaline Treatment and Characterization of the Alkali-Treated Humins Formed [PDF]

open access: yesACS Sustainable Chemistry and Engineering, 2015
The valorization of the humin byproducts that are formed during hydrothermal, acid-catalyzed dehydration of carbohydrates is hampered by the insolubility of these byproducts. Here, we report on an alkaline pretreatment method that allows for the insolubility of this highly recalcitrant and structurally complex feed to be overcome.

RIP1 Contributes to Colorectal Cancer Progression and Lymphatic Remodeling in Association With VEGF‐C/NF‐κB Pathway [PDF]

open access: yesFASEB BioAdvances
Receptor‐interacting protein kinase 1 (RIP1) plays a regulatory role in inflammation and cell survival, but its involvement in colorectal cancer (CRC), particularly in relation to lymphatic changes within the tumor microenvironment, remains poorly ...

Effect of Lignin, Humins, and Biomass-Derived Acids on Kinetics of Catalytic Hydroxymethylfurfural Production during Saccharide Dehydration Reactions. [PDF]

open access: yesChemSusChem
(Hemi)celluloses, abundant in lignocellulosic biomass, can be hydrolyzed and dehydrated into furanics like 5‐hydroxymethylfurfural (5‐HMF) and levulinic acid. Despite its potential, 5‐HMF production remains limited by inefficiencies, notably humin formation.

Characterisation of the organic components of peat and implications for the binding of toxic trace elements [PDF]

open access: yesMires and Peat, 2022
We aimed to determine the distribution of toxic elements amongst the organic components of peat collected from raised bogs located in the Arkhangelsk region of Russia, and thus to gain new insights about the ability of peat to accumulate these elements ...

The associations between concentrations of gestational bisphenol analogues and thyroid related hormones in cord blood: A prospective cohort study

open access: yesEcotoxicology and Environmental Safety, 2023
Animal studies indicated that Bisphenol analogues (BPs) exhibited potential thyroid toxicity. However, little is known of the associations between maternal BPs exposure and offspring’s thyroid related hormones in humans.
