Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Tuning Colloidal Stability and Photothermal Conversion Efficiency of Graphite Nanofluids via Anionic‐Nonionic Surfactant Engineering

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

Food Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

Light‐Driven Butyrate Production by a Probiotic Clostridium tyrobutyricum Enabled by a Cell‐Semiconductor Hybrid Interface

Food Chemistry International, EarlyView.
This schematic illustrates a light‐driven biohybrid system where CdS nanoparticles, mineralized on the probiotic Clostridium tyrobutyricum, inject photoelectrons to elevate intracellular NADH. This boosts the flux through key NADH‐dependent enzymes (GapA, Hbd, and Bcd), reprogramming metabolism to enhance butyrate yield by 33.2% and selectivity to 95.7%

Donkwa Enriched With Goron‐Tula (Azanza garckeana) Modulates Sexual Behavior and Activity of Enzymes Linked With Erectile Dysfunction in High‐Fat Diets/ Streptozotocin‐Induced (STZ/HFD) Diabetic Rats

Food Chemistry International, EarlyView.
(A) Mount number, (B) mount latency, (C) intromission number, and (D) intromission latency are the parameters of sexual behavior. Met = metformin. D100 = 100 Donkwa. D90G10 = 90% Donkwa + 10% Goron‐Tula. D85G15 = 85% Donkwa + 15% Goron‐Tula. D80G20 = 80% Donkwa + 20% Goron‐Tula. The mean ± standard error of the mean (SEM) expressed the results. *Values

Optimising the Eco‐Friendly Extraction of Carotenoids From Gac Fruit: A Sustainable Solution for Natural Red Food Colourants

Food Chemistry International, EarlyView.
Gac fruit's high carotenoid content, especially in the aril, makes it an excellent natural red pigment source for food applications, offering a safer alternative to synthetic dyes. Ethanol extraction achieved the highest overall pigment recovery (89.53%), whereas ethyl lactate extraction yielded the highest levels of total carotenoids, β‐carotene ...
