Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...

Determination of bisphenol A, bisphenol F, bisphenol A diglycidyl ether and bisphenol F diglycidyl ether migrated from food cans using Gas Chromatography-Mass Spectrometry

Czech Journal of Food Sciences, 2003
Varnishes used for the inner coatings of food cans are mostly based on epoxy resins or vinylic organosols. The epoxy resins are produced from bisphenol A and bisphenol F and they also contain BADGE or BFDGE as stabilising components.

Bisphenol A in dummies

, 2009
The Federal Institute for Risk Assessment (BfR) examined dummies made of latex and sili-cone for bisphenol A. The goal was more particularly to determine how much bisphenol A migrates from the dummies during use.

Estrogenic Potency of a Bisphenol A Metabolite on Vitellogenin Synthesis in Medaka, Oryzias latipes [PDF]

, 2005
We investigated the estrogenic activity of a bisphenol A (BPA) metabolite (4-methyl-2,4-bis(p-hydroxyphenyl)-pent-1-ene; MBP) in male medaka (Oryzias latipes) using vitellogenin (Vg, Vg1 and Vg2) as a biomarker.

Urinary Bisphenols as Biomarkers of Exposure to Bisphenol A, Bisphenol F, and Bisphenol S: A New Procedure for Biomonitoring

Laboratories
Introduction. Bisphenols are chemicals widely used in industrial production, but they are also of significant concern due to their potential health effects. In particular, bisphenol A (BPA) is a documented endocrine disruptor. As a result, bisphenol S (BPS) and bisphenol F (BPF) are now frequently used as substitutes.

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Enhanced Electron‐Capturing by Single‐Atomic Iron on Pyridinic N‐Deficient Carbon Drives Self‐Oxidative Degradation of Pollutants

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Pyrolysis of FeOx/g‐C3N4 and ZIF‐8 is performed to introduce Fe single atom and pyridinic nitrogen vacancies onto N‐doped carbon. This modification enables the materials to efficiently extract electrons from ciprofloxacin (CIP) and activate dissolved oxygen. 100% of CIP was degraded within 1 min without adding any oxidant.

Bisphenol S, a New Bisphenol Analogue, in Paper Products and Currency Bills and Its Association with Bisphenol A Residues

, 2012
As the evidence of the toxic effects of bisphenol A (BPA) grows, its application in commercial products is gradually being replaced with other related compounds, such as bisphenol S (BPS). Nevertheless, very little is known about the occurrence of BPS in

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 ...
