In this paper, photoinduced controlled radical polymerization (PI-CRP) provided excellent temporal and spatial control over a wide range of irradiation wavelengths (450-850 nm). Polymers with controllable mol. weight and narrow mol. weight distribution were synthesized using amphiphilic ethidium iodide (EI) as a catalyst and 2-iodine-2-methylpropanenitrile as an initiator in controlled radical polymerization of hydrophilic methacrylates in aqueous solution and oleophilic methacrylates in bulk under the irradiation of white, blue, green, red, and near-IR (NIR) light, and sunlight. Moreover, no polymerization occurred without light irradiation, indicating that the polymerization was an ideal photo “on”-“off” switchable system.

The feasibility of polymerizations under the irradiation of such a wide range of wavelengths by an organic catalyst both in bulk and aqueous solutions was an unprecedented feature. The advantages of this polymerization included simple preparation of catalysts, adsorption of broadband light, ease of operation and applicability to a wide range of polymer designs.

The design and development of agonists selectively targeting thyroid hormone receptor β (TRβ) and TRβ mutants remain challenging tasks. In this study, we first adopted the strategy of breaking the “His-Phe switch” to solve two problems, simultaneously. A structure-based design approach was successfully utilized to obtain compound 16g (I), which is a potent TRβ agonist (EC₅₀: 21.0 nM, 85.0% of the maximum efficacy of 1) with outstanding selectivity for TRβ over TRα and also effectively activates the TRβ^H435R mutant. Then, we developed a highly efficient synthetic method for 16g. Our serials of cocrystal structures revealed detailed structural mechanisms in overcoming subtype selectivity and rescuing the H435R mutation. 16g also showed excellent lipid metabolism, safety, metabolic stability, and pharmacokinetic properties. Collectively, 16g is a well-characterized selective and mutation-sensitive TRβ agonist for further investigating its function in treating dyslipidemia, nonalcoholic steatohepatitis (NASH), and resistance to thyroid hormone (RTH).

Li, Mengya;Zhang, Junle;He, Yanjie;Zhang, Xiaomeng;Cui, Zhe;Fu, Peng;Liu, Minying;Shi, Ge;Qiao, Xiaoguang;Pang, Xinchang research published 《 Dual enhancement of carrier generation and migration on Au/g-C₃N₄ photocatalysts for highly-efficient broadband PET-RAFT polymerization》, the research content is summarized as follows. Photoinduced electron/energy transfer RAFT (PET-RAFT) polymerization can produce well-defined polymers with spatiotemporal control. Semiconducting graphitic carbon nitride (g-C₃N₄), as a thermally and chem. stable photocatalyst, has accomplished the PET-RAFT method under UV-irradiation and blue-light. However, its catalytic efficiency was decreased by the high recombination rate of photogenerated electron-hole pairs, while the control over polymerization was weakened by the UV-decomposition of RAFT reagents. Herein, a series of Au/g-C₃N₄ composite photocatalysts were facilely prepared by the deposition-precipitation method. Arrangement of Au nanoparticles (NPs) on g-C₃N₄ displayed hot electron injection or plasmon-induced resonance energy transfer, which boosts the generation of active electrons for a broadband PET-RAFT process (460-740 nm). The formation of a Schottky barrier enhanced the carrier migration, as it lowered the charge recombination rate. Such a synergistic effect made Au/g-C₃N₄ outperform Au NPs, g-C₃N₄ and their phys. blend. Furthermore, the effects of the Au content, hole scavenger, chain transfer agent, monomer, solvent, and light-source on the highly efficient PET-RAFT polymerization were studied.

V.;He, Fangjian research published 《 Microwave drying of balsam pear with online aroma detection and control》, the research content is summarized as follows. Volatile odor is one of the major sources of food flavor. To preserve the aroma components of balsam pear during drying, a microwave drying system was designed with online volatile detection and control ability. Balsam pear slices were first dried at fixed temperatures (50 °C, 65 °C, 80 °C), and the representative aroma volatiles were compared and analyzed. By detection of aroma volatiles during drying process, a fuzzy logic control assisted with zNose was further developed that could retain normal aroma and suppress burning aroma, thus the final product quality could be greatly improved. An industrialized control was finally designed to mimick the temperature curve in the fuzzy logic control without zNose attendance. The color difference, flavor, vitamin C, chlorophyll, and sensory evaluation of products with the industrialized control suggested well accepted quality. Hence the microwave drying with aroma process control has the potential to be used in large-scale industrial applications.

Li, Dan;Liu, Nan;Zeng, Min;Ji, Jinzhao;Chen, Xi;Yuan, Jinying research published 《 Customizable nano-sized colloidal tetrahedra by polymerization-induced particle self-assembly (PIPA)》, the research content is summarized as follows. Colloidal mols. (CMs) are colloidal clusters with mol.-like symmetry and architecture, generated from the self-assembly of nanoparticles with attractive patches. However, the large-scale preparation of patchy nanoparticles remains challenging. Here, we synthesize CH₄-like colloidal tetrahedra (CTs) in a scalable way by aqueous polymerization-induced particle self-assembly (PIPA), where isotropic diblock copolymer spheres are used as seeds. During PIPA, the newly formed third block aggregates into attractive patches, which bridge the isotropic spheres together to form CTs in situ, as a result of surface energy minimization. This approach surpasses previous reports in its scalability, high yield and versatility. For example, the purity of as-prepared CTs reaches 78.3% at a concentration of 100 g L-1, which allows the 3D reconstruction of the tetrahedral structure by single particle electron microscopy anal. The versatility of PIPA is illustrated by preparing CMs of tunable size, valency and various chem. structures. In addition, the architecture of the CMs can be manipulated after the PIPA process simply by the addition of ethanol, for example, the CTs can be transformed into ladder-like structures, paving a new avenue to access hierarchical nanoscale self-assemblies.
