PHENOLIC COMPOSITION, TOTAL PHENOLIC CONTENT AND ANTIOXIDANT ACTIVITY OF PARSLEY POST-DISTILLATION RESIDUES [PDF]
Physical Chemistry 2024 : proceedings Vol. 2Essential oil of parsley can be extracted from the leaves and seeds and it is used in pharmaceutical, cosmetics as well as in the food industry as a natural food additive. However, the large amount of solid plant residues remaining after essential oil production represents a valuable source of polyphenols and other bioactive phytochemicals.

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories
Advanced Engineering Materials, EarlyView.Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...

Advanced Engineering Materials, EarlyView.The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
