Zwillinger, Marton;Reddy, Post Sai;Wicher, Barbara;Mandal, Pradeep K.;Csekei, Marton;Fischer, Lucile;Kotschy, Andras;Huc, Ivan research published 《 Aromatic Foldamer Helices as α-Helix Extended Surface Mimetics》, the research content is summarized as follows. Helically folded aromatic oligoamide foldamers have a size and geometrical parameters very distinct from those of α-helixes and are not obvious candidates for α-helix mimicry. Nevertheless, they offer multiple sites for attaching side chains. It was found that some arrays of side chains at the surface of an aromatic helix make it possible to mimic extended α-helical surfaces. Synthetic methods were developed to produce quinoline monomers suitably functionalized for solid phase synthesis. A dodecamer was prepared Its crystal structure validated the initial design and showed helix bundling involving the α-helix-like interface. These results open up new uses of aromatic helixes to recognize protein surfaces and to program helix bundling in water.

Name: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., 72824-04-5.

Zubrytski, Dzmitry M.;Elek, G. Abor Zolt An;Lopp, Margus;Kananovich, Dzmitry G. research published 《 Generation of mixed anhydrides via oxidative fragmentation of tertiary cyclopropanols with phenyliodine(III) dicarboxylates》, the research content is summarized as follows. Oxidative fragmentation of tertiary cyclopropanols with phenyliodine(III) dicarboxylates in aprotic solvents (dichloromethane, chloroform, toluene) produces mixed anhydrides. The fragmentation reaction is especially facile with phenyliodine(III) reagents bearing electron-withdrawing carboxylate ligands (trifluoroacetyl, 2,4,6-trichlorobenzoyl, 3-nitrobenzoyl), and affords 95 -98% yields of the corresponding mixed anhydride products. The latter can be straightforwardly applied for the acylation of various nitrogen, oxygen and sulfur-centered nucleophiles (primary and secondary amines, hydroxylamines, primary alcs., phenols, thiols). Intramol. acylation yielding macrocyclic lactones can also be performed. The developed transformation has bolstered the synthetic utility of cyclopropanols as pluripotent intermediates in diversity-oriented synthesis of bioactive natural products and their synthetic congeners. For example, it was successfully applied for the last-stage modification of a cyclic peptide to produce a precursor of a known histone deacetylase inhibitor.

This study explores the feasibility of utilizing recycled fine aggregates (RFA) in 3D mortar printing (3DMP) by evaluating the properties of 3D printing (3DP) mixtures with different contents of RFA (0%, 50%, and 100%) as well as sodium gluconate (0%, 0.6%, and 1.2%) before and after high-rate shearing from the perspective of rheol., failure pattern and buildability. The results showed that, the incorporation of RFA highly increased the 3DP mixture’s initial value and time-varying rate of the static yield stress, viscosity and area of thixotropy hoop, while adding sodium gluconate decreased them resp. Meanwhile, since high-rate shearing were found to highly decrease the mentioned rheol. parameters of 3DP mixtures, a feeding system which can provide high-rate and continuous shearing was recommended in practical printing to prolong the open time of printing mixtures Besides, a dimensionless buildability parameter λ was proposed and defined as the ratio of accumulated offsets (whether compression or tension) to the theor. height to describe the buildability of 3DP mixtures, which exhibited much higher accuracy than the maximum printing layer, maximum printing height and average vertical strain, resp.

Zou, Dinghua;Zhang, Zhenjie;Wang, Dongming research published 《 Influence of citric acid and sodium gluconate on hydration of calcium sulfoaluminate cement at various temperatures》, the research content is summarized as follows. To reveal the effect of set retarders on calcium sulfoaluminate (CSA) cement at different temperatures, plain paste and retarded ones with citric acid and sodium gluconate were prepared Curing temperatures of 20, 30 and 40°C were adopted. Initial and final setting times of fresh paste were measured. Compressive strength of samples at 1 day, and 3, 7, and 28 days were tested. XRD, DSC-TG and SEM were used to reveal the impact of retarders on hydration and microstructure of CSA cement. Results reveal that, retarders extend the setting of CSA cement paste, however accelerate the hydration of it at later age. Finer and more AFt is observed in retarded paste. Nevertheless, rise of temperature diminishes the retarding effect of citric acid and sodium gluconate and meanwhile inhibits the hydration of CSA cement with and without retarders. On most occasions, compressive strength of CSA cement paste increases when retarders are employed with the content up to 1.5%. At the content of 0.5 or 0.25%, retarded pastes achieve the highest compressive strength gains relative to their plain counterpart. This varies with the type of retarders and curing temperature For citric acid and sodium gluconate, the contents are 0.25 and 0.5% at 20°C, resp. With the rise of temperature to 30 and 40°C, the contents are 0.5 and 0.25%, resp. Rise of temperature from 20 to 30°C enhances the gain of compressive strength. However, similar gains are observed at temperatures of 30 and 40°C.

Zhu, Pengfei;Jiang, Linhua;Shi, Yanran;Xu, Ning;Jin, Ming research published 《 Influence of retarders on hydration and microstructure development of cement containing high-volume limestone powder》, the research content is summarized as follows. Limestone powder is widely used in concrete for efficient reduction in hydration heat in the place lacking common supplementary cementitious materials. The sodium gluconate and citric acid have been commonly used as retarders to extend the setting time of concrete during summer construction. To study the influence of retarders on hydration and microstructure development of cement containing high-volume limestone powder, multi-technique methods are employed. Isothermal calorimetry, thermogravimetric anal., X-ray diffraction, mercury intrusion porosimetry and energy-dispersive X-ray analyses in the SEM are used to investigate the hydration process, the content of hydration products, the species of the hydration products, the pore structure of cement pastes and the composition of C-S-H. The results show that the retarders have a better inhibition effect on the hydration of cement containing high-volume powder limestone than on that of cement without limestone powder. At a given dosage, the citric acid has a stronger interaction with the cement containing 30% limestone powder than the sodium gluconate. For the cement containing a high volume of limestone powder, the presence of retarders induces a higher porosity, a larger critical radius and a lower average Ca/Si ratio of C-S-H at 28 curing days. The porosity and the volume fraction pore size smaller than 50 nm have a linear relationship with the hydration degree and the gel/space ratio, resp. However, the critical radius of cement pastes has an exponential relationship with the hydration degree and gel/space ratio, resp.

Zhu, Meng-Zeng;Xie, Dong;Tian, Shi-Kai research published 《 Highly Regioselective Aromatic C-H Allylation of N-(Arylmethyl)sulfonimides with Allyl Grignard Reagents Involving Benzylic C-N Cleavage》, the research content is summarized as follows. A new pair of reaction partners has been established for the aromatic C-H functionalization of benzyl electrophiles with nucleophiles via palladium-catalyzed benzylic C-N cleavage. A range of N-(1-naphthylmethyl)sulfonimides, N-(2-thienylmethyl)sulfonimides, and N-(2-furanylmethyl)sulfonimides smoothly underwent palladium-catalyzed aromatic C-H allylation with allyl Grignard reagents at room temperature, delivering structurally diverse substituted 1-allylnaphthalenes and 2-allylheteroarenes in moderate to excellent yields with extremely high regioselectivities. Replacing the N-(arylmethyl)sulfonimide with an (arylmethyl)ammonium salt, an arylmethyl chloride, or an arylmethyl phosphate as the benzyl electrophile leads to a dramatic erosion of the regioselectivity.

Zhou, Yutang;Shen, Yichao;Shi, Liangjie;Jin, Yong;Lai, Shuangquan;Tang, Yujia research published 《 Synthesis, characterization and properties of novel nonionic hydrocarbon/fluorocarbon hybrid surfactants containing a short fluoroalkyl chain》, the research content is summarized as follows. A series of novel nonionic hydrocarbon/fluorocarbon hybrid surfactants (Hm-Fn, where m = 10, 12, 14, 16 and n = 4, 6, resp.) were successfully synthesized using polyethylene glycol, isophorone diisocyanate (IPDI), short chain fluoroalkyl alc. and alkyl alc. as starting materials. The preparation process involves the coupling reaction of isocyanate and hydroxyl groups. The surface activity and aggregation behavior of Hm-Fn in aqueous solution were studied by surface tension, steady-state fluorescence and dynamic light scattering (DLS) and transmission electron microscopy (TEM). The influence of the hydrophobic (hydrocarbon or fluorocarbon) chain length on surface activity of such hydrocarbon/fluorocarbon hybrid surfactants was systematically investigated. Micromorphol. anal. revealed the presence of different sizes vesicles in H16-F6 and H16-F4 aqueous solution In addition, the hydrophobic dye solubilization experiments exhibited that H16-F6 with a relatively longer fluorocarbon chain and hydrocarbon chain possessed more outstanding solubilization of model dye (Sudan I) compared with other Hm-Fn and conventional hydrocarbon surfactants. The molar solubilization power of H16-F6 could reach 0.0537. The above results demonstrated that these nonionic hydrocarbon/fluorocarbon hybrid surfactants might possess potential application prospects for hydrophobic dyes solubilization.

Zhou, Rong;Jin, Yong;Shen, Yichao;Lai, Shuangquan;Zhou, Yutang;Zhao, Peng research published 《 Surface activity, salt and pH tolerance, and wettability of novel nonionic fluorinated surfactants with a short fluorocarbon chain》, the research content is summarized as follows. Fluorinated surfactants, especially those with long fluorocarbon chains (C_xF_2x+1, x > 7) like perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), are used wildly in industrial and household fields. As research results have shown that such long fluorocarbon chain surfactants are seriously toxic, obviously persistent and highly bioaccumulative in the environment, it is an urgent requirement to develop novel alternatives of the long fluorocarbon chain surfactants. In this work, a series of novel nonionic fluorinated surfactants (FxCy-m) was synthesized by introducing an isophorone diisocyanate unit (as a spacer) between a short hydrophobic fluorocarbon chain (x ≤ 6) and a hydrophilic polyethylene glycol (PEG) chain with a facile two-step couple reaction using com. available reagents. The chem. structures of FxCy-m were characterized by FT-IR and ¹H NMR, and the relationships between length of hydrophilic/hydrophobic chains and surface activity of FxCy-m were systematically investigated by surface tension measurements. Among them, F6C2-400 with a longer fluorocarbon chain and a shorter PEG chain exhibits the highest surface activity, and its capability of reducing surface tension is almost equivalent to that of NaPFO (a derivative of PFOA). Meanwhile, F6C2-400 also has an excellent tolerance to salt and pH as well as an effective wettability. The facile preparation method and the clear structure-activity relationship in our research provide a valuable reference for development of nonionic surfactants with a short fluorocarbon chain.

Zhou, Rong;Jin, Yong;Lai, Shuangquan;Shi, Liangjie;Bai, Long;Peng, Zhangyi research published 《 A novel composite retanning system based on pH-responsive hydrogen bonding and hydrophobic interaction for cleaner leather processing》, the research content is summarized as follows. Aldehyde-tanned leather is one of the promising choices to avoid the widespread chrome pollution in leather industry. Due to the lack of metal ions, the aldehyde-tanned leather not able to effectively fix traditional anionic retanning materials, which seriously affects the quality of aldehyde-tanned leather. Herein, a novel composite retanning system consisting of acrylic resin (AR) and F6-600 (a nonionic fluorinated surfactant with poly(ethylene oxide) (PEO)) was constructed, which breaks through the dependence of conventional leather materials on metal ions in terms of fixation. The main acting mechanism is that at the final stage of retanning, after reducing the float pH, pH-responsive hydrogen bonding and hydrophobic interaction synergistically drive AR/F6-600 to self-assemble into bigger polymer composite aggregates, and then these aggregates are forced to deposit and fill in leather fiber gaps, thus obtaining more desirable retanning results. Furthermore, AR/F6-600 composite retanning system is eco-friendly. The AR/F6-600 retanned leather has lower free formaldehyde content, better biodegradability, and higher uptake rates for subsequent dye and fatliquoring agent, which can further eliminate the threat of formaldehyde to health, accelerate the degradation of waste leather in the nature, and reduce the chem. residual in wastewater, resp. Consequently, this novel retanning system will benefit to satisfy evolving demands for related technologies toward cleaner leather production
