Statistical approach to optimization of the transesterification reaction from sorrel (hibiscus sabdariffa) oil [PDF]
, 2012 In an effort to optimize the reaction conditions of biodiesel production from Sorrel seed oil, Response Surface Methodology (RSM) was applied and the effects of reaction temperature, catalyst amount, reaction time and methanol/oil molar ratio, and ...

Macromolecular Rapid Communications, EarlyView.We successfully developed poly(ethylene terephthalate) (PET) and poly(ethylene furanoate) (PEF) nanoparticles and microparticles, covalently tagged with Alexa Fluor 633 or Alexa Fluor 647, using both mechanical and solvent‐based approaches. The particles displaying hydrodynamic diameters between 200 and 700 nm, exhibited long‐term colloidal stability ...

Robust β‐myrcene block copolymer elastomeric vitrimers
Polymer International, EarlyView.Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Journal of Polymer Science, EarlyView.A D‐optimal design of experiments maps the influence of key reaction parameters on enzymatic ε‐caprolactone polymerization. Thus linking multivariate conditions to conversion, molar mass characteristics, and by‐product formation, whilst demonstrating that biobased solvents offer viable, sustainable media for polyester synthesis.

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.We present a new catalytic process that converts real‐life PET waste into ethyl 4‐hydroxymethylbenzoate (EHMB), which serves as a valuable intermediate for the synthesis of pharmaceuticals, an insecticide, and a novel polyester. Abstract We report here the upcycling of PET (polyethylene terephthalate) waste via semihydrogenation to make ethyl 4 ...

Journal of Vinyl and Additive Technology, EarlyView.Adjusting extrusion variables are a key to balance the flame retardancy and mechanical properties of polyolefin/leather waste fiber composites. ABSTRACT The extrusion processing variables represent a key to the optimal use of additives and thus the development of flame‐retardant polymer composites. Adjusting the property profile, for example, finding a

Journal of Fish Biology, EarlyView.Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Production and Evaluation of Biodiesel from Sheep Fats Waste
Iraqi Journal of Chemical and Petroleum Engineering, 2012 Animal fats are a good, promising and ethical alternative source for biodiesel production, but they need more complex treatments than vegetable oils. Iraqi butchery plants waste fats (sheep fat) which are suggested as feedstock to produce biodiesel. This
