Continuous, high-throughput production of artemisinin-loaded supramolecular cochleates using simple off-the-shelf flow focusing device
Lipid cochleates are gaining increasing interest as drug-carriers. However, their preparation relies on conventional batch processes that are complex, time consuming and lack batch-to-batch reproducibility; presenting a bottleneck for clinical translation. We report an efficient continuous preparation process for artemisinin-loaded cochleates (ART-cochleates) using inexpensive off-the-shelf flow
Crystal Chemistry and SAXS Studies of an Octahedral Polyoxoarsenotungstate Nanocluster Encapsulating Four Unprecedented Thorium Arsenate Fragments (Th3As2On n = 25 or 26)
Dufaye, Maxime; Duval, Sylvain; Stoclet, Grégory; Loiseau, Thierry
The reaction of 8 with the 5f tetravalent thorium cation in presence of an acetate buffer and KCl at pH = 4.7 gives rise to the formation of an octahedral polyoxoarsenotungstate nanocluster 38. This molecule is constructed around four unprecedented Th3As2On (n = 25 or 26) fragments stabilized by the…
In-Depth Study of Coating Multimodal Porosity Using Ellipsometry Porosimetry in Desorption Scanning Mode
Loizillon, Jérôme; Baumgartner, Bettina; Sinturel, Christophe; Abbarchi, Marco; Lendl, Bernhard; Grosso, David
Ellipsometry porosimetry provides full adsorption/desorption isotherms and is among the most accurate techniques to probe porosity in thin films. Here we address a novel technique based on desorption scanning for a precise assessment of the porosity features revealing the size distribution of interconnections between the various populations of pores in…
Lignin@Nafion Membranes Forming Zn SolidElectrolyte Interfaces Enhance the Cycle Life for Rechargeable Zinc-Ion Batteries
Yuan, Du; Manalastas, William; Zhang, Liping; Chan, Jun Jie; Meng, Shizhe; Chen, Yingqian; Srinivasan, Madhavi
Metallic zinc is an ideal anode material for rechargeable zinc-ion batteries (ZIBs), taking us beyond the lithium-ion era. In-depth understanding of the Zn metal surface is currently required owing to diverse but uncorrelated data about the Zn surface in mild environments. Herein, the surface chemistry of Zn is elucidated and…
Moebius strips of chiral block copolymers
Geng, Zhen; Xiong, Bijin; Wang, Liquan; Wang, Ke; Ren, Min; Zhang, Lianbin; Zhu, Jintao; Yang, Zhenzhong
The Moebius topology (twisted, single-sided strip) is intriguing because of its structural elegance and distinct properties. Here we report the generation of block copolymer Moebius strips via a fast self-assembly of chiral block copolymer polystyrene-block-poly(D-lactide acid) (PS-b-PDLA) in tetrahydrofuran/water mixed solvents. The Moebius strip is formed by morphological evolution from…
Adsorption of organic pollutants by amine functionalized mesoporous silica in aqueous solution. Effects of pH, ionic strength and some consequences of APTES stability
Otalvaro, Julian Ortiz; Avena, Marcelo; Brigante, Maximiliano
A mesoporous silica with MCM-41 type pore array was synthesized by hydrothermal method and then was functionalized with known amounts of 3-aminopropyltriethoxysilane (APTES) in order to study the selective adsorption towards several species/pollutants. Antibiotics doxycycline hydrochloride (DC) and norfloxacin (NFX), the dye methyl orange(MO) and the pesticide 2,4-dichlorophenoxyacetic acid
Synergistic Enhancement of CO2 Adsorption Capacity and Kinetics in Triethylenetetrammonium Nitrate Protic Ionic Liquid Functionalized SBA-15
Zhang, Wei; Gao, Erhao; Li, Yu; Bernards, Matthew T.; Li, Younan; Cao, Guanghan; He, Yi; Shi, Yao
A series of triethylenetetrammonium nitrate protic ionic liquid (TNPIL) functionalized, highly ordered mesoporous SBA-15 molecular sieves with different loadings have been synthesized via impregnation. The CO2 capture performance of the hybrid sorbents was evaluated under conditions mimicking a combustion flue gas (15% CO2) over the temperature range of 298348 K.…
Correlation between mechanical properties and microscopic structures of an optimized silica fraction in silicone rubber
Liu, Dong; Song, Lixian; Song, Hongtao; Chen, Jie; Tian, Qiang; Chen, Liang; Sun, Liangwei; Lu, Ai; Huang, Chaoqiang; Sun, Guangai
The mechanical properties and the hierarchical filler structures were characterized on a series silica-filled silicone rubber with a filler fraction (?Si) varied from 0.05?phr to 80?phr (parts per hundred rubber). Uniaxial elongation measurement suggests that there is a percolation threshold between 10 and 30?phr. Moreover, an optimum ?Si range from…
Ion Transport in Pendant and Backbone Polymerized Ionic Liquids
Kuray, Preeya; Noda, Takeru; Matsumoto, Atsushi; Iacob, Ciprian; Inoue, Tadashi; Hickner, Michael A.; Runt, James
Polymerized ionic liquids (PILs) are single-ion conductors in which one of the ionic species is tethered to the polymer chain while the other is free to be transported. The ionic species can either be directly incorporated into the polymeric backbone (backbone PILs) or placed as pendant groups to the chain…
Direct modification of polyketone resin for anion exchange membrane of alkaline fuel cells
Zhou, Yi-Cun; Zhou, Ling; Feng, Chang-Ping; Wu, Xiao-Tian; Bao, Rui-Ying; Liu, Zheng-Ying; Yang, Ming-Bo; Yang, Wei
A kind of side-chain type anion exchange membranes (AEMs) with high ionic conductivity and good comprehensive stability was prepared via direct modification of commercial engineering plastic polyketone with diamines through Paal-Knorr reaction and quaternization reaction. It was found that the amount of diamine can effectively tune the microphase morphology and…
