Controlled‐Atmosphere thermal demagnetization and paleointensity analyses of extraterrestrial rocks
Geochemistry Geophysics Geosystems, 2014Co-Authors: Clément Suavet, Benjamin P. Weiss, Timothy L. GroveAbstract:We describe a system for conducting thermal demagnetization of extraterrestrial rocks in a Controlled Atmosphere appropriate for a wide range of oxygen fugacities within the stability domain of iron. Thermal demagnetization and Thellier-Thellier paleointensity experiments on lunar basalt synthetic analogs show that the Controlled Atmosphere prevents oxidation of magnetic carriers. When combined with multidomain paleointensity techniques, this opens the possibility of highly accurate thermal demagnetization and paleointensity measurements on rocks from the Moon and asteroids.

different postharvest strategies to preserve broccoli quality during storage and shelf life Controlled Atmosphere and 1 mcp
Food Chemistry, 2013Co-Authors: M F Fernandezleon, A M Fernandezleon, M Lozano, M C Ayuso, David GonzalezgomezAbstract:Abstract Broccoli (Brassica oleracea var. italica) is a vegetable that requires the application of postharvest techniques to extend its marketability. Controlled Atmosphere and 1-MCP treatments are most used to extend the shelf life of broccoli and reduce post-harvest deterioration. The aim of this study was to evaluate the visual, physicochemical and functional changes of broccoli head samples stored at 1–2 °C and 85–90% relative humidity (RH) in air (Control samples), under Controlled Atmospheres (10% O2 and 5% CO2) (CA samples) and treated with 1-MCP (0.6 μL/L). After storage all samples were maintained at 20 °C for 2 and 4 days, in order to assess their shelf life. The most suitable postharvest treatment to extend broccoli quality during storage and shelf life, in terms of maintaining the visual quality and reducing loss of health-promoting compounds, was achieved by storage under Controlled Atmosphere conditions. The use of 1-MCP reduced the loss of green colour and chlorophyll pigments, but only during cold storage not during shelf life at 20 °C.

altered commercial Controlled Atmosphere storage conditions for parhenon broccoli plants brassica oleracea l var italica influence on the outer quality parameters and on the health promoting compounds
Lwt - Food Science and Technology, 2013Co-Authors: M F Fernandezleon, A M Fernandezleon, M Lozano, M C Ayuso, David GonzalezgomezAbstract:Abstract Parameters such as bright and dark green compact heads, firmness to hand pressure and closed florets, and the evolution of main health-promoting compounds such as carotenoid and chlorophyll pigments, phenolic compounds and glucosinolates, were assessed to determine the effects of the Atmosphere composition during the cold storage of broccoli ‘Parthenon’. The Controlled Atmosphere evaluated in this study was a gas mixture containing 10% of O 2 and 5% of CO 2 , with 85–90% relative humidity. The storage temperature was established at 1 and 2 °C. We found that the loss of weight and firmness was greater in the reference samples compared to samples stored under Controlled Atmosphere conditions (20.60% and 84.88%, for loss of weight and firmness in reference samples respectively, and 4.80% and 16.48%, for loss of weight and firmness in Controlled Atmosphere samples respectively) after 9 days of storage, approximately. In addition, the proposed Controlled Atmosphere conditions helped to maintain the concentration of the main health-promoting compounds, such as ascorbic acid, carotenoid and chlorophylls pigments, total phenolic compounds and intact glucosinolates, and the values of the antioxidant activity in vitro were also maintained.

Process-microstructure-property relationships in Controlled Atmosphere plasma spraying of ceramics
Surface and Coatings Technology, 2017Co-Authors: Sébastien Beauvais, Mary Espanol, François Borit, Michel Jeandin, Vincent Guipont, Agathe Robisson, Khiam Aik Khor, R. SaengerAbstract:Thermal plasma spray processes with their various operating parameters can be considered a flexible technique to carry out appropriate manufacturing of advanced ceramics coatings. This paper reports on investigations dealing with plasma spraying of several ceramics powders (hydroxyapatite, Al2O3–TiO2, Al2O3, ZrO2–Y2O3 (YSZ) and Cr2O3) with suitable parameters using a ‘Controlled Atmosphere plasma spraying' (CAPS) system. High-pressure plasma spraying, air plasma spraying and inert plasma spraying modes were applied in order to obtain suitable microstructures in the coatings. The investigation of microstructures and phase compositions showed that high-pressure in the CAPS chamber leads to sufficient heating of the powder and have a promising coating quality.

label free quantitative proteomics to investigate strawberry fruit proteome changes under Controlled Atmosphere and low temperature storage
Journal of Proteomics, 2015Co-Authors: Zisheng Luo, Xinhong Huang, Lu Zhang, Pengyu Zhao, Zhaojun Ban, Xia LiuAbstract:Abstract To elucidate the mechanisms contributing to fruit responses to senescence and stressful environmental stimuli under low temperature (LT) and Controlled Atmosphere (CA) storage, a label-free quantitative proteomic investigation was conducted in strawberry ( Fragaria ananassa , Duch. cv. ‘Akihime’). Postharvest physiological quality traits including firmness, total soluble solids, total acidity, ascorbic acid and volatile production were characterized following storage under different conditions. The observed post-storage protein expression profiles may be associated with delayed senescence features in strawberry. A total of 454 proteins were identified in differentially treated strawberry fruits. Quantitative analysis, using normalized spectral counts, revealed 73 proteins common to all treatments, which formed three clusters in a hierarchical clustering analysis. The proteins spanned a range of functions in various metabolic pathways and networks involved in carbohydrate and energy metabolism, volatile biosynthesis, phenylpropanoid activity, stress response and protein synthesis, degradation and folding. After CA and LT storage, 16 (13) and 11 (17) proteins, respectively, were significantly increased (decreased) in abundance, while expression profile of 12 proteins was significantly changed by both CA and LT. To summarize, the differential variability of abundance in strawberry proteome, working in a cooperative manner, provided an overview of the biological processes that occurred during CA and LT storage. Biological significance Controlled Atmosphere storage at an optimal temperature is regarded to be an effective postharvest technology to delay fruit senescence and maintain fruit quality during shelf life. Nonetheless, little information on fruit proteomic changes under Controlled Atmosphere and/or low temperature storage is available. The significance of this paper is that it is the first study employing a label-free approach in the investigation of strawberry fruit response to Controlled Atmosphere and cold storage. Changes in postharvest physiological quality traits including volatile production, firmness, ascorbic acid, soluble solids and total acidity were also characterized. Significant biological changes associated with senescence were revealed and differentially abundant proteins under various storage conditions were identified. Proteomic profiles were linked to physiological aspects of strawberry fruit senescence in order to provide new insights into possible regulation mechanisms. Findings from this study not only provide proteomic information on fruit regulation, but also pave the way for further quantitative studies at the transcriptomic and metabolomic levels.
