Hydrothermal treatment of ZnO nanostructures

Thin Solid Films, 2012
Abstract Hydrothermal treatment of ZnO nanostructures involves low temperatures (150–200 °C) and elevated water vapor pressure for the purpose of the improvement in the material properties. Under such moderate conditions, no significant changes in the morphology would be expected.

Heat and hydrothermal treatments of non-wheat flours

Food Chemistry, 2021
Non-wheat cereals have become popular in the diet due to their nutritional benefits, but their application is limited by properties of their proteins. Some of these flours can be conventionally processed, but the final products are not of acceptable quality.

Treatment of urban sludge by hydrothermal carbonization

Bioresource Technology, 2017
Urban sludge was treated by Hydrothermal carbonization (HTC). The effect of hydrothermal carbonization temperature, mixing with or without catalysts on solid products yield, heavy metal contents, turbidity and COD value was evaluated. The result showed solid products yield decreased from 92.04% to 52.65% when the temperature increased from 180 to 300°C.

Fractionation of sugarcane bagasse by hydrothermal treatment

Bioresource Technology, 2003
Hydrothermal treatment of sugarcane bagasse was conducted using a semi-batch reactor to develop a new biomass fractionation method that has low impact in the environment. A continuously increasing temperature was used in this treatment. It was found that hemicellulose and lignin could be mainly extracted as a water-soluble fraction at 200-230 degrees C,

Hydrothermal treatment of electric arc furnace dust

Journal of Hazardous Materials, 2011
In this study, ZnO crystals were fabricated from electric arc furnace dust (EAFD) after alkaline leaching, purification and hydrothermal treatment. The effects of temperature, duration, pH, and solid/liquid ratio on ZnO crystal morphology and size were investigated. Results show a high reaction temperature capable of accelerating the dissolution of ZnO

Heat transfer analysis during hydrothermal treatment of mango

Journal of Food Science, 2022
Abstract To export Mexican mango fruit, it is required to comply with phytosanitary regulations, which implies heat transfer. Foods are biological systems with a dynamic behavior and, when they are thermally processed, their thermophysical properties change with temperature.

Hydrothermal Treatment of Coprecipitated YSZ Powders

Materials Science Forum, 2010
Zirconia stabilized with 8.5 mol% yttria (YSZ) were synthesized by coprecipitation and resulting gels were hydrothermallly treated at 200°C and 220 PSI for 4, 8 and 16 hours. Products were oven dried at 70°C for 24 hours, isostatically pressed as pellets and sintered at 1500 °C for 1 hour.

Smart hydrothermally responsive microneedle for topical tumor treatment

Journal of Controlled Release, 2023
Locoregional therapy has attracted increasing attention for subcutaneous tumors owing to its merits of minimally invasive operation and negligible systematic toxicity. However, to accelerate clinical translation, further promotions in deep-seated penetration, temporal-spatial controllability, personalized adaptability, as well as easy operation are ...

Dehulling of canola by hydrothermal treatments

Journal of the American Oil Chemists' Society, 1995
Hydrothermal pretreatments for loosening the hull of Westar canola (Brassica napus L.) to promote dehulling of the seeds were investigated. The samples tested had on average 14.5% hull on a mass basis. Conditioning treatments involved soaking the seeds in distilled water or exposing the seeds to saturated steam.
