Article Abstract
The direct acrylation of soybean oil was investigated by the activation of soybean oil's (SO's) internal fatty unsaturation with acidic catalysts. The effect of the catalyst and the reactant ratio with respect to the unsaturation and reaction time on the direct acrylation process were explored. ASO (acrylated soybean oil) with acrylation degrees (the number of acrylate molecules introduced in a triglyceride molecule) between 1.6 and 2.55 were obtained. The effect of the ASO acrylation degree on copolymerization processes was investigated. The resulting monomers were successfully copolymerized with meth(acrylate) monomers by the miniemulsion polymerization process, favoring the droplet nucleation mechanism and showing conversions higher than 97%. The acrylic-ASO copolymers presented lower Tg and higher hydrophobicity and oleophobicity than the acrylic copolymer.

Background: Analyzing the (trace) metal content of synthetic polymers is of interest both for manufacturing and recycling industries where inorganic additives and contaminations must be monitored. Additionally, the metal content of microplastics has recently gained more and more attention as a means to assess their environmental impact. LA-ICP-MS is commonly used for this task as it provides superior sensitivity and allows direct analysis of non-conductive samples.

Circularly polarized organic light-emitting diodes (CP-OLEDs) are essential to prospective 3D displays and advanced polarized lighting systems. The rational design of programmable circularly polarized electroluminescence (CP-EL) materials with a large electroluminescence dissymmetry factor (g) remains a great challenge and is still in its preliminary exploration phase. In this work, two aggregation induced emission active (AIE-active) chiral inducers with different dihedral angles of binaphthalene (S-/R-1 and S-/R-2) and achiral acrylate-based liquid crystalline polymer (LCP) (PyP) were chosed to construct chiral co-assemblies through an intermolecular chirality induction mechanism.

The recovery of noble metals from industrial wastewater, printed circuit boards and end-of-life electronics is very important to ensure the availability of these non-renewable sources in the future. Metal recycling can be afforded through different solution-based methods including reductive precipitation, oxidative dissolution, solvent extraction, or adsorption. The latter is particularly appealing due to its simplicity and potential selectivity, which can be tailored by a wide range of materials.

Pipelines are extensively used in environments such as nuclear power plants, chemical factories, and medical devices to transport gases and liquids. These tubular environments often feature complex geometries, confined spaces, and millimeter-scale height restrictions, presenting significant challenges to conventional inspection methods. Here, we present an ultrasonic microrobot (weight, 80 mg; dimensions, 24 mm × 7 mm; thickness, 210 μm) to realize agile and bidirectional navigation in narrow pipelines.
