Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

open access: yesEnvironmental 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 ...

A Bifunctional UiO‐66 Platform Enabled by Schiff‐Base Engineering for CO2 Conversion and Epoxide–Anhydride Copolymerization

open access: yesSmall, EarlyView.
Bifunctional UiO‐66‐Schiff‐base‐M(II) (M = Zn, Cu, Ni) MOF catalysts enable efficient and selective epoxide/anhydride copolymerization and CO2/epoxide coupling under mild conditions. The catalysts feature tunable Lewis acidity, high recyclability, and structural robustness, offering a sustainable platform for green polymer synthesis and carbon dioxide ...

Adsorption Characteristics of Benzene Carboxylic Acids from Aqueous Solution by Zr(IV)-loaded Collagen Fiber

open access: yes工程科学与技术, 2010
:A novel adsorbent, Zr(IV)-loaded collagen fiber (ZLCF), was prepared and its adsorption characteristics to benzoic acid (BA), o-phthalic acid (o-PA), p-phthalic acid (p-PA) and m-phthalic acid (m-PA) from aqueous solution were investigated. It was found

Effects of phthalic acid esters on the liver and thyroid. [PDF]

open access: yesEnvironmental Health Perspectives, 1986
The effects, over periods from 3 days to 9 months of administration, of diets containing di-2-ethylhexyl phthalate are very similar to those observed in rats administered diets containing hypolipidemic drugs such as clofibrate. Changes occur in a characteristic order commencing with alterations in the distribution of lipid within the liver, quickly ...

Fracture load and three‐dimensional internal void analysis of direct composites used to restore worn molars

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

New Biobased Polyester Polyols With Tunable Tg Values From 4‐Vinylguaiacol‐Derived Monomers

open access: yesChemSusChem, Volume 19, Issue 15, 14 August 2026.
Biobased low‐molecular‐weight polyesters were obtained by ROCOP of guaiacol‐derived epoxides with cyclic anhydrides. Varying the length of the acyl moieties on the epoxides and the cyclic anhydride structures, it is possible to tune the Tg's within an 80 ºC wide temperature range.
