Wang, Teng-Wei;Huang, Pin-Ruei;Chow, Jayme L.;Kaminsky, Werner;Golder, Matthew R. research published 《 A Cyclic Ruthenium Benzylidene Initiator Platform Enhances Reactivity for Ring-Expansion Metathesis Polymerization》, the research content is summarized as follows. Ring-expansion metathesis polymerization (REMP) has shown potential as an efficient strategy to access cyclic macromols. Current approaches that utilize cyclic olefin feedstocks suffer from poor functional group tolerance, low initiator stability, and slow reaction kinetics. Improvements to current initiators will address these issues in order to develop more versatile and user-friendly technologies. Herein, we report a reinvigorated tethered ruthenium-benzylidene initiator, CB6, that utilizes design features from ubiquitous Grubbs-type initiators that are regularly applied in linear polymerizations We report the controlled synthesis of functionalized cyclic poly(norbornene)s and demonstrate that judicious ligand modifications not only greatly improve kinetics but also lead to enhanced initiator stability. Overall, CB6 is an adaptable platform for the study and application of cyclic macromols. via REMP.

Wang, Yansong;Sun, Xiaolong;Han, Qingxin;James, Tony D.;Wang, Xuechuan research published 《 Highly sensitive and selective water-soluble fluorescent probe for the detection of formaldehyde in leather products》, the research content is summarized as follows. Excess formaldehyde (FA) provides a significant threat that causes irreversible damage to both the environment and human health, and long-term FA emission from com. leather products is a significant problem. Therefore, to help control the FA content, we propose a fluorescence-based method to detect FA selectively using a reaction-based probe FAP-1. Water-soluble FAP-1 was simply synthesized through two steps and the optical properties of FAP-1 towards species relevant to leather making were evaluated. Then a number of genuine leather samples were analyzed to reveal the FA content. Compared with the international standards, the fluorescence method was competitive to the 2,4-dinitrophenylhydrazine (DNPH) reaction-based HPLC method, and superior to the acetylacetone (ACAC) reaction-based UV-Vis method. As a result of its reliability, low-cost, simple synthesis, ease of operation with reduced measurement time compared with standard methods, our method exhibits great potential for the anal. of FA found in other industrial products.

Wang, Hao;Gao, Yihang research published 《 High Inhibition of Bentonite Hydration by Use of a Homopolymer Containing Synergistic Bi-Functional Groups》, the research content is summarized as follows. Most current inhibitors control bentonite hydration at the partial phase by the single adsorption mode. To improve inhibition and action range, we synthesized a novel homopolymer inhibitor (PIM-NH2) containing bi-functional groups. Comprehensive experiments investigated the inhibition of PIM-NH2 and other inhibitors. In immersion and linear expansion experiments, the hydration swelling of bentonite cake was incredibly restrained in 0.75% PIM-NH2 solution The greater contact angle between 0.75% PIM-NH2 solution and bentonite cake indicated the retardation of water invasion. According to XRD anal., the intercalation of 0.75% PIM-NH2 reduced the bentonite lattice spacing from 1.91 nm to 1.27 nm with water discharge. All results suggested PIM-NH2 had an outstanding performance at the lower concentration, and its inhibition covered the whole hydration process. Mechanism investigation revealed two synergistic adsorptions (hydrogen bond and electrostatic attraction) of bi-functional groups exerted simultaneously to improve each other. In FT-IR spectra, the hydrogen bond was confirmed by the special frequency movement from 1550 cm-1 to 1641 cm-1. The electrostatic attraction decreased the ζ potential absolute value from 29.55-33.20 mV to around 4 mV. In ESEM anal., the bentonite treated by 0.75% PIM-NH2 showed larger aggregates and rough surfaces, demonstrating dehydration properties.

Wang, Hao;Gao, Yihang;Jia, Xuhong;Liu, Quanyi research published 《 Properties and mechanism of a poly(ionic liquid) inhibitor contained bi-functional groups for bentonite hydration》, the research content is summarized as follows. Present polymer inhibitors depend on a major inhibitory group to restrain bentonite hydration, and monomer design is concerned to improve the inhibition and stability through complex copolymerization Conveniently, a homopolymer (PIL-NH₂) that contained primary amine and cationic imidazolium as bi-functional groups was proposed, aiming to provide two synergistic inhibitory modes. Comprehensive methods were conducted to characterize the chem. structure and inhibitory performance of PIL-NH₂. The ζ potential absolute value of bentonite suspension was decreased by PIL-NH₂ from 28.7-33.3 mV to 4-7 mV, and the increment of bentonite particle size d₅₀ was observable from 1.83892μm to over 200μm. With water squeezed out, the lattice spacing d₀₀₁ of hydrated bentonite was reduced from 1.9070 to 1.2683 nm due to PIL-NH₂ intercalation. The ESEM images revealed that inhibited bentonite showed a tight structure with classical dehydration phenomenon, and the hydrogen bond between PIL-NH₂ and bentonite was further confirmed according to the FT-IR result. In mechanism anal., the electrostatic attraction and hydrogen bond existed simultaneously for PIL-NH₂ to adsorb bentonite. The two adsorption modes from bi-functional groups were synergistic to improve inhibition remarkably. PIL-NH₂ maintained high performance during the whole hydration process, including crystalline hydration, osmotic hydration, and hydrated dispersion.
