Oxidative stability of UV irradiated and X-rayed soybean oil incorporated with rose oil

Grasas y Aceites, 2019
The effects of UV radiation and X-ray on the oxidative stability of soybean oil were investigated. Also, rose oil was incorporated into soybean oil and its antioxidant activity was compared with that of α-tocopherol during accelerated storage.

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Optimizing solar UV-radiation exposures for vitamin D3: comparing global and diffuse spectral UV radiation

, 2008
Currently, there is a major gap in the knowledge that is needed in order to optimise the beneficial effects related to ultraviolet (UV) radiation for vitamin D3 synthesis (UVD3) compared to reducing the biologically damaging overexposure to UV radiation.

LIGHT MODULATED PHENOLIC SYNTHESIS IN CHENOPODIUM QUINOA MICROGREENS AS A POTENTIAL BIOTECHNOLOGICAL TOOL

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2023
Chenopodium quinoa microgreens are a culinary product that, as well as other species, is rich in bioactive, health promoting compounds. The present paper shows that light spectrum alone can be used as a convenient tool for enhancing phenolic synthesis in

UV Damage of the Hair

Collegium antropologicum, 2009
Hair is a very important for our self-confidence as well as a very important part of appearance and self-concept. It reflects our personality and hair loss or hair damages are considered aesthetic imperfections and social handicap. Outward part of the hair is a "hair shaft" keratin fiber structure sensible to external effects whether they are ...

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

Advanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...
