Fast 3D P B mapping with a weighted stack of spiral trajectory at 7 Tesla.

Purpose: Phosphorus Magnetic Resonance Spectroscopy (P MRS) enables non-invasive assessment of energy metabolism, yet its application is hindered by sensitivity limitations. To overcome this, often high magnetic fields are used, leading to challenges such as spatial inhomogeneity and therefore the need for accurate flip angle determination in accelerated acquisitions with short repetition times . In response to these challenges, we propose a novel short and look-up table-based Double-Angle Method for fast 3D P mapping (fDAM).

Unexpected acceleration of Ultrasonic-Assisted iodide dosimetry in the catalytic presence of ionic liquids.

This study investigates the potential of using small amounts of ionic liquids (IL) to enhance ultrasound-assisted extraction of lipids content from green microalgae. Three imidazolium-based ILs (butyl, octyl and dodecyl), each of them with two anions (bromide and acetate) were tested as additives. Viscosity and surface tension of the ILs aqueous mixtures were analyzed to determine the influence of ILs' anions and alkyl chain length, whereas KI dosimetry experiments were used as an indicator of radicals formation.

Sonochemical activity in ultrasonic reactors under heterogeneous conditions.

Due to its physical and chemical effects, ultrasound is widely used for industrial purposes, especially in heterogeneous medium. Nevertheless, this heterogeneity can influence the ultrasonic activity. In this study, the effect of the addition of inert glass beads on the sonochemical activity inside an ultrasonic reactor is investigated by monitoring the formation rate of triiodide, and the ultrasonic power is measured by calorimetry and by acoustic radiation.

Rheological and physicochemical stability of hydrolyzed jackfruit juice ( L.) processed by spray drying.

Spray drying represents a viable alternative for the stabilization of juice and extract of a great diversity of plant in tropical zones, such as jackfruit from Nayarit, Mexico. The jackfruit powder allows physicochemical and microbiological stability for storage, transportation, and marketing. In addition, this allows expansion of consumption and use of these exotic tropical fruits.
