Obst, Marc F.;Gevorgyan, Ashot;Bayer, Annette;Hopmann, Kathrin H. research published 《 Mechanistic Insights into Copper-Catalyzed Carboxylations》, the research content is summarized as follows. The Cu-NHC-catalyzed carboxylation of organoboranes with CO₂ was studied using computational and exptl. methods. The DFT and DLPNO-CCSD(T) results indicate that nonbenzylic substrates are converted via an inner-sphere carboxylation of an organocopper intermediate, whereas benzylic substrates may simultaneously proceed along both inner- and outer-sphere CO₂ insertion pathways. The computations predict that two conceptually different carboxylation mechanisms are possible for benzylic organoboranes, one being Cu-catalyzed and one being mediated by the reaction additive CsF. The authors’ exptl. evaluation of the computed reactions confirms that carboxylation of nonbenzylic substrates requires Cu catalysis, whereas benzylic substrates can be carboxylated with and without Cu.

Oba, Yasuhiro;Takano, Yoshinori;Furukawa, Yoshihiro;Koga, Toshiki;Glavin, Daniel P.;Dworkin, Jason P.;Naraoka, Hiroshi research published 《 Identifying the wide diversity of extraterrestrial purine and pyrimidine nucleobases in carbonaceous meteorites》, the research content is summarized as follows. The lack of pyrimidine diversity in meteorites remains a mystery since prebiotic chem. models and laboratory experiments have predicted that these compounds can also be produced from chem. precursors found in meteorites. Here we report the detection of nucleobases in three carbonaceous meteorites using state-of-the-art anal. techniques optimized for small-scale quantification of nucleobases down to the range of parts per trillion (ppt). In addition to previously detected purine nucleobases in meteorites such as guanine and adenine, we identify various pyrimidine nucleobases such as cytosine, uracil, and thymine, and their structural isomers such as isocytosine, imidazole-4-carboxylic acid, and 6-methyluracil, resp. Given the similarity in the mol. distribution of pyrimidines in meteorites and those in photon-processed interstellar ice analogs, some of these derivatives could have been generated by photochem. reactions prevailing in the interstellar medium and later incorporated into asteroids during solar system formation. This study demonstrates that a diversity of meteoritic nucleobases could serve as building blocks of DNA and RNA on the early Earth.

We report the first systematic exptl. and theor. study of the relationship between the linker functionalization and the thermodn. stability of metal-organic frameworks (MOFs) using a model set of eight isostructural zeolitic imidazolate frameworks (ZIFs) based on 2-substituted imidazolate linkers. The frameworks exhibit a significant (30 kJ·mol^-1) variation in the enthalpy of formation depending on the choice of substituent, which is accompanied by only a small change in molar volume. These energetics were readily reproduced by d. functional theory (DFT) calculations We show that these variations in the enthalpy of MOF formation are in linear correlation to the readily accessible properties of the linker substituent, such as the Hammett σ-constant or electrostatic surface potential. These results provide the first quantifiable relationship between the MOF thermodn. and the linker structure, suggesting a route to design and tune MOF stability.

Northcutt, Katharine V.;Leal-Medina, Tanya S.;Yoon, Ye S. research published 《 Early postnatal hypothyroidism reduces juvenile play behavior, but prenatal hypothyroidism compensates for these effects》, the research content is summarized as follows. Perinatal hypothyroidism causes long-lasting effects on behavior, including hyperactivity, cognitive delays/deficits, and a reduction in anxiety. Although there is some evidence that hypothyroidism during fetal development in humans has been associated with later autism spectrum disorder diagnosis or autism-like traits, the relationships between early thyroid hormones and social behaviors are largely unknown. Previously, we found that a moderate dose of the hypothyroid-inducing drug methimazole during embryonic and postnatal development dramatically increased juvenile play in male and female rats. The goal of the current study was to determine the extent to which thyroid hormones act in prenatal or postnatal development to organize later social behaviors. Subjects were exposed to methimazole in the drinking water during prenatal (embryonic day 12 to birth), postnatal (birth to postnatal day 23), or pre- and postnatal development; control animals received regular drinking water throughout the experiment They were tested for play behavior as juveniles (P30-32). We found an interaction between pre- and postnatal methimazole administration such that postnatal hypothyroidism decreased some play behaviors, whereas sustained pre- and postnatal hypothyroidism restored play to control levels. The effects were similar in males and females. To our knowledge, this is the first report of an interaction between pre- and postnatal hypothyroidism on later behavior. The complexity of the timing of these effects may help explain why epidemiol. studies have not consistently found a relationship between gestational hypothyroidism and later behavior.

Niu, Zhen;Wu, Ruiyao;Yang, Yinxin;Huang, Lingyun;Fan, Weifeng;Dai, Quanquan;Cui, Long;He, Jianyun;Bai, Chenxi research published 《 Recyclable, robust and shape memory vitrified polyisoprene composite prepared through a green methodology》, the research content is summarized as follows. Due to the weak mech. performance of raw rubber, it cannot meet the actual use requirements, thus crosslinking and reinforcement have been the eternal theme of rubber materials. However, this permanent crosslinking structure brings the dilemma that the rubber materials cannot be recycled after the life cycle, which causes energy waste and serious environmental pollution. Herein, we present a facile and green methodol. to prepare covalently cross-linked yet recyclable and robust polyisoprene-based vitrimer. The carboxylated carbon nanodots (CNDs) were selected as both crosslinkers and reinforcing components to react with epoxidized polyisoprene (EPI) for the construction of dynamic crosslinked networks with exchangeable β-hydroxyl ester bonds for the first time. The dynamic covalent linkages endowed the EPI-based vitrimers with reprocessability and excellent shape memory performance. In addition, the dynamic exchangeable interface enables CNDs well-dispersed in the EPI matrix, which exhibited high reinforcement efficiency on the mech. properties of EPI composite.

Niizeki, Takeru;Hoshina, Taka-Aki;Takahashi, Tomoki research published 《 Characterizations of thermo-responsive alkyl imidazolium perchlorates for forward osmosis membrane process》, the research content is summarized as follows. The forward osmosis (FO) process uses a spontaneous water permeation phenomenon driven by an osmotic pressure difference between a feed solution (FS) and a draw solution (DS) through a semipermeable membrane. Hence, it is assumed that seawater desalination and feed solution concentration using FO processes can be conducted at low energy and cost. It is crucial to develop an optimal DS for the FO process before it can be put into practical use. The DS must have the following characteristics: (1) Develops higher osmotic pressure than FS, (2) Easy to regenerate and recover, (3) Low leakage, and (4) Low viscosity. Particularly, we propose low-grade waste heat to reduce energy consumption during DS regeneration and chose a temperature phase transition type DS that separates into water and solute components based on thermal response. In this study, we synthesized six alkyl imidazolium type ionic liquids (ILs) having perchlorate anion ([ClO₄]), phase transition characteristics, and osmotic pressure, and the consequent FO performance was examined The synthesized ILs, 1-ethyl-3-propylimidazolium perchlorate [Im (2.0.3)] [ClO4] and 1,2-dimethyl-3-propylimidazolium perchlorate [Im(1.1.3)][ClO₄], showed an upper critical solution temperature type phase transition in the temperature range of 25 ° to 50 °. The FO test confirms that pure water can be derived from saltwater using the osmotic pressure of DS. In comparison to other synthesized ILs, [Im (1.1.3)] [ClO₄] showed higher performance in phase diagrams and osmotic pressure.

Aliphatic polymers, such as polypropylene, styrene ethylene butylene styrene and norbornene, which show great alk. stability and flexibility, have become the main research trend of the skeleton of anion exchange membranes. Here, we prepared a copolymer with all carbon atoms on the main chain. Firstly, a new vinylimidazole cationic monomer was prepared, and then copolymerized with styrene and acrylonitrile to obtain a copolymer (PASIm). Furthermore, (2,6-dimethyl-1,4-phenylene oxide) (PPO) was introduced to crosslink with PSAIm to prepare AEMs with different crosslinking degrees (CEM-X, X = 6,12,18,24,30). 1H NMR and FT-IR showed that PASIm was successfully synthesized and crosslinked with PPO. The prepared membranes had high hydroxide ionic conductivity and excellent alk. stability. AFM showed that the CEM-18 had obvious microphase separation structure, which was beneficial to the construction of ion channels in the membrane. Thus, the CEM-18 showed the highest ionic conductivity, up to 59.21 mS cm-1 at 80°C. CEM-24 with higher crosslinking degree showed the highest alk. stability. After immersing in 1 M KOH solution at 80°C for 240 h, 86.52% of the initial ionic conductivity was retained. These results indicate that the prepared anion exchange membranes have broad application prospects.
