Cruciferous oilseeds are important sources of oil, proteins, and glucosinolates (GLs), potentially available when biorefinery processes are used. The proposed extraction technology is based on the use of reverse micelles (RMs) made with cetyltrimethylammonium bromide (CTAB) dispersed in organic solvent. The physicochemical properties of this extraction system and the good water solubility of many high value compounds, such as GLs and some proteins, permit the simultaneous extraction of oil, and these products from cruciferous oilseed meals. This procedure is based on three main steps: (i) seed conditioning; (ii) solid-liquid extraction by RM solution; and (iii) back-transfer of the RM solution for recovery of the extracted compounds. The method makes it possible to simultaneously extract almost the same amount of oil as with pure organic solvents used in the current extraction plants and more than 90% of soluble proteins and GLs. It is a promising biorefinery technology alternative to traditional oil extraction processes.

The endosomal escape of lipid nanoparticles (LNPs) is crucial for efficient mRNA-based therapeutics. Here, we present a cationic polymeric micelle (cPM) as a safe and potent co-delivery system with enhanced endosomal escape capabilities. We synthesized a cationic and ampholytic di-block copolymer, poly (poly (ethylene glycol) methacrylate--hexyl methacrylate)--poly(butyl methacrylate--dimethylaminoethyl methacrylate--propyl acrylate) (p(PEGMA--HMA)--p(BMA--DMAEMA--PAA)), via reversible addition-fragmentation chain transfer polymerization.

Spin crossover (SCO) iron (II) coordination compounds in the form of nanohybrid SCO@SiO particles were prepared using a reverse micelles technique based on the TritonX-100/cyclohexane/water ternary system. Tetraethyl orthosilicate (TEOS) acts as precursor of both the SiF counter-anion and SiO to obtain Fe(NHtrz)(BF)(SiF)@SiO nanoparticles with different sizes and morphologies while modifying the TEOS concentration and reaction time. The adjustable mixed-anion strategy leads to a range of quite scarce abrupt spin crossover behaviors with hysteresis just above room temperature (ca.

In an effort to mitigate or reverse the pathological progression of early-stage osteonecrosis of the femoral head (ONFH), this study employed a promising strategy that involves the sustained delivery of osteogenic factors to augment core decompression, facilitated by the use of composite hydrogels. Specifically, a hydrogel was synthesized by blending chitosan, Pluronic F-127, and tripolyphosphate, utilizing both ionic bonding and copolymer micelle cross-linking techniques. This hydrogel demonstrated exceptional biocompatibility, temperature responsiveness, pH-dependent biodegradation, and controlled release properties.

Due to the fact that association colloids were formed in krill oil, the oxidation mechanism of krill oil was more complicated. In this study, water-soluble ferrous sulfate (Fe(SO)), oil-soluble ferrous fumarate (CHFeO) and insoluble ferric oxide (FeO) were added to krill oil and stored at 60 °C for accelerated oxidation. Peroxide value, thiobarbituric acid reactive substances and aldehyde content showed that Fe(SO) had a stronger pro-oxidative effect.

Experiments: We explore the influence of alkanes with varying chain lengths on the rheological properties, structural parameters, and morphology of RWLMs. To establish a link between the solvent characteristics and the structure of RWLMs, we employ a diverse set of complementary techniques, including rheological analysis, small-angle X-ray scattering (SAXS), Fourier-transform infrared (FT-IR) spectroscopy, and cryogenic transmission electron microscopy (cryo-TEM).
