The measurement of adsorbed surfactant is important to fields such as corrosion inhibition, metal cleaning, and separation technologies. The electrochemical quartz crystal microbalance (EQCM) is an important tool that can be used to measure adsorbed surfactant. However, such measurements are subject to significant temperature and viscosity effects that must be appropriately considered. This paper discusses the effect of temperature and viscosity on EQCM measurements in solution environments and the ability of the EQCM to measure surfactant adsorption.

Unlabelled: The effects of high hydrostatic pressure (HHP) (400-650 MPa) and holding temperature (25-50 °C) in thermally assisted HHP processing on multi-scale structure of starch (granule, crystalline and molecular), techno-functional properties, and digestibility of sorghum starch (SS) were evaluated. Response surface methodology has verified that the process impact on the modification of SS was dependent primarily on the pressure level. As HHP increased, processed SS progressively lost their granular structure and Maltese cross, indicating gradual structural disorder within the granules.

To study the characteristics of bread by incorporating nutrient-rich quinoa flour as a new source for product development. Wheat flour was replaced by fractionated quinoa flour in different variations from 0%QF to 20%QF: 0%, 5%, 10%, 15%, and 20% WQF blends, respectively. Physicochemical studies resulted in higher protein and fiber content for the higher blend.

brown seaweed () is reported to exhibit several biological activities that promote human health, but it does not have the ability to withstand harsh environmental conditions, such as high temperatures and oxygen exposure. Encapsulation of extraction through different techniques is known to, optimize physicochemical properties, biological activities, maintain stability, and is an effective way to improve the shelf life of different foods. In the present study, the encapsulation of SIE was carried out by the freeze-drying method using maltodextrin, whey protein isolate (WPI), and chitosan.

Due to the high viscosity and low fluidity of viscous crude oil, how to effectively recover spilled crude oil is still a major global challenge. Although solar thermal absorbers have made significant progress in accelerating oil recovery, its practical application is largely restricted by the variability of solar radiation intensity, which is influenced by external environmental factors. To address this issue, this study created a new composite fiber that not only possesses solar energy conversion and storage capabilities but also facilitates crude oil removal.
