Bio‐Based Solvents Extraction and Enzyme‐assisted Recovery of Furan Fatty Acid From Ammonia‐Stabilized Hevea Latex

European Journal of Lipid Science and Technology, EarlyView.
The latex of Hevea brasiliensis is rich in furan fatty acid (FuFA) esterified in both neutral and polar lipids. Bio‐based solvents to extract FuFA from ammonia‐stabilized latex was tested. Ethyl acetate worked best, especially with low‐ammonia content. Isopropanol was a good alternative. Lipases could also help to efficiently release FuFA. The findings

Transition Metal‐Free Carboxylation of Aryl Boronates in Supercritical CO2

European Journal of Organic Chemistry, EarlyView.
Transition metal‐free carboxylation of aryl boronates catalyzed by ZnO is achieved by using supercritical CO2. Cage‐shaped cyclic trialkoxyboronates, which are both nucleophilic and soluble in supercritical CO2, undergo the carboxylation efficiently in supercritical CO2 at high pressure and temperature to give corresponding aromatic carboxylic acids ...

Are physiological oscillations physiological?

The Journal of Physiology, EarlyView., 2023
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Research on the Characteristics and Mechanisms of Supercritical CO2 Displacement of Shale Oil Under Nanoscale Confinement

Energy Science &Engineering, EarlyView.
ABSTRACT Shale reservoirs, characterized by compact pores, poor physical properties, and high organic matter content, exhibit significant differences in microscopic flow behavior compared to conventional oil reservoirs. These distinctions complicate the accurate assessment of shale oil reserves and the selection of optimal exploration and development ...

Distribution Simulation of SC‐CO2 Carrying Proppants in Multicluster of Fractures Under Different Perforations

Energy Science &Engineering, EarlyView.
A physical model of multicluster fractures in horizontal well with perforation segments. ABSTRACT Supercritical carbon dioxide (SC‐CO2) fracturing is a new type of waterless staged multicluster fracturing. Different from one single fracture, the slurry almost simultaneously flows to multiple fractures in staged multicluster fracturing, resulting in a ...
