Background: Orange peel essential oils were obtained using supercritical fluid extraction. This method is an important high scaling extraction methods that used for extraction of plant and animal extracts. Methodology: The experimental parameters of SFE such as temperature, pressure, and extraction time and modifier volume were optimized using a central composite design after a 24-1fractional ...

in order to investigate the effect of temperature and time of blanching process on the generation and extraction of reducing sugars and kinetics of color changes during blanching, the potato strips packaged in the polyethylene (hdpe with 10 micron thickness) film or without polyethylene packaging, were immersed in distilled water at temperature range of 50, 60, 70, 80 and 90 ºc for 120 minutes....

Xylan can be extracted from biomass using either alkali (KOH or NaOH) or dimethyl sulfoxide (DMSO); however, DMSO extraction is the only method that produces a water-soluble xylan. In this study, DMSO extraction of corn stover was studied at different temperatures with the objective of finding a faster, more efficient extraction method. The temperature and time of extraction were compared follo...

Nanoporous carbons (CMK-3) were prepared and have been used as a fiber coating for headspace solid phase microextraction (HS-SPME). The prepared materials were characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and N2 adsorption/desorption isotherms. The efficiency of the fiber was evaluated using a gas chromatography (GC) system for the extraction of benzene (B) and c...

A flow-through ultrasonic separator constructed entirely from PMMA has been demonstrated for the first time. Continuous extraction of lipids from milk has been achieved. Construction is simple, requiring channels to be embossed at low temperatures (120°C) with a room temperature solvent bond used to close the channel.

Abstract A series resistance extraction method proposed recently, which uses multiple drain current versus gate voltage curves at varied voltages, was applied to bulk CMOS devices low temperatures down 4 K. moderate reduction of compared with 300 K found. Horizontal field dependence mobility significantly changed temperature, taken into account during the extraction. Anomalous non-linear observ...

Superheated water extraction is used to extract essential oil of leaves of Origanum micranthum. The effect of different temperatures on the essential oil profile and rate of extraction as a function of time is investigated. The components of essential oil of Origanum micranthum are removed from the aqueous extract by C18 solid-phase extraction. The identification of components is carried out us...

Surface amorphization provides unprecedented opportunities for altering and tuning material properties. Surface-amorphized TiO2@graphene synthesized using a designed low temperature-phase transformation technique exhibits significantly improved rate capability compared to well-crystallized TiO2@graphene and bare TiO2 electrodes. These improvements facilitates lithium-ion transport in both inser...

producing parts with high density and improved mechanical properties is one of the most important aims of powder metallurgy process. there are many factors for attaining modified properties in sintered parts but among them controlling type and quantity of alloying elements and manufacturing parameters such as compacting pressure, sintering temperature are the most effective.in this research, tw...

The research aimed at developing an optimal procedure for the extraction of soybean saponins from lowtemperature soybean meal with microwave treatment combined with enzymatic hydrolysis (MTEH), and studied the antioxidant activity of soybean saponins. The result shows that the optimal parameters of microwave treatment, determined with the orthogonal array design method, were the medium fire of ...
