Humin-sulfuric acid as a novel recoverable biocatalyst for pyrrole synthesis in water [PDF]

open access: yesBMC Chemistry
Humin-sulfuric acid (Humin-SO3H) as a novel efficient biobased sulfonic acid was easily prepared by adding chlorosulfuric acid (ClSO3H) to Humin and characterized by potentiometric titration and FT-IR spectrum.

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

Changes in Soil Humin Macromolecular Structure Resulting from Long-Term Catch Cropping [PDF]

open access: yesMolecules
The aim of this study was to assess the effect of long-term catch crop application on the structural properties of humin, which is considered the most recalcitrant fraction of soil organic matter. Soil samples from a 30-year field experiment on triticale

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.

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 ...

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 ...

Promotion of Nitrogen Fixation of Diverse Heterotrophs by Solid-Phase Humin

open access: yesFrontiers in Microbiology, 2022
Although biological nitrogen fixation (BNF) proceeds under mild conditions compared to the energy-intensive Haber–Bosch process, the slow kinetics of BNF necessitate the promotion of BNF activity in its practical application.

Urease and β-glucosidase activity enhanced the transformation of functional groups of humin amended by straw and straw-derived biochar

open access: yesChemical and Biological Technologies in Agriculture, 2022
Background Organic materials carbon is mainly sequestrated in humin. However, the carbon (C) stability of humin with organic materials amendments in different types of soils is mainly affected by organic materials or soil types as well as the enzymatic ...

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.

ISOLATION OF ORGANIC MATTER BY THE NAOH-HCL METHOD FROM TWO MARINE OIL SHALES USING OVEN AND SEALED AUTOCLAVE TECHNIQUES; pp. 197–213 [PDF]

open access: yesOil Shale, 2019
Organic matter (OM) was isolated from two marine oil shales, El-Lajjun and Julia Creek, using NaOH-HCl and humin and humic acid frac­tions separated. Two treatments were required to reduce humin ash yield to below 11 wt% db.
