Structural and Dynamical Properties of Water Confined in Highly Ordered Mesoporous Silica in the Presence of Electrolytes
The structural and dynamical properties of water confined in highly ordered mesoporous silica (SBA-15) in the presence of ions having various kosmotropic properties (XCl2 with X = Ba2+, Ca2+, and Mg2+) were characterized using thermogravimetric analysis, infrared spectroscopy, and quasi-elastic neutron scattering and were related to the surface density of…
Aluminum pillared montmorillonite clay-based self-healing coatings for corrosion protection of magnesium alloy AZ91D
Adsul, Swapnil H.; Siva, T.; Sathiyanarayanan, S.; Sonawane, Shirish H.; Subasri, R.
In the present study, aluminum pillared montmorillonite clay was modified with cationic corrosion inhibitors Ce3+/Zr4+. The modification of the montmorillonite clay was carried out by two methods; (a) by simple mixing of inhibitor solutions along with clay by stirring for 30 min and (b) by homogenization of inhibitor solutions and clay…
Interaction of the Saponin Aescin with Ibuprofen in DMPC Model Membranes
Sreij, Ramsia; Prévost, Sylvain; Dargel, Carina; Dattani, Rajeev; Hertle, Yvonne; Wrede, Oliver; Hellweg, Thomas
In the present work, we study the interaction of the saponin aescin with the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen at concentrations of 1.2–2.5 mM. These amounts are higher than those usually used for medication (10–300 μM) to show possible structures and formulations for orally absorbed drug delivery systems. It is…

Kong, Weiqing; Wang, Chengwei; Jia, Chao; Kuang, Yudi; Pastel, Glenn; Chen, Chaoji; Chen, Gegu; He, Shuaiming; Huang, Hao; Zhang, Jianhua; Wang, Sha; Hu, Liangbing
Biological tissues generally exhibit excellent anisotropic mechanical properties owing to their well-developed microstructures. Inspired by the aligned structure in muscles, a highly anisotropic, strong, and conductive wood hydrogel is developed by fully utilizing the high–tensile strength of natural wood, and the flexibility and high-water content of hydrogels. The wood hydrogel…
Inkless Writing and Self-Erasing Security Feature of (Z)-1,2-Diarylacrylonitrile-Based Materials: A Confidential Data Communication
Panda, Tamas; Maiti, Dilip K.; Panda, Manas K.
Development of a novel organic luminescent material for inkless writing, and self-erasing application is a remarkable solution to reduce paper waste, recycling cost in the printing industry. These innovative materials also offer to reduce global warming due to the lower consumption of paper made from plants. To this endeavor, herein…
Crystalline structure, dielectric, and mechanical properties of simultaneously biaxially stretched polyvinylidene fluoride film
Lu, Hongchao; Li, Li
Biaxially stretched films have balanced properties in the film plane compared with uniaxially stretched films, thus having wider potential applications. In this paper, the simultaneously biaxial stretching (BO) technology had been applied to poly (vinylidene fluoride) (PVDF) melt extrusion film, and the crystalline structure, dielectric, and mechanical properties of the…
Isoporous membranes with sub-10 nm pores prepared from supramolecular interaction facilitated block copolymer assembly and application for protein separation
Zhu, Guo-dong; Ying, Yu-rong; Li, Xuan; Liu, Yang; Yang, Cao-ying; Yi, Zhuan; Gao, Cong-jie
Isoporous membranes with pore size smaller than 10 nm are significantly important for molecular separation. However, preparation of such membranes from process containing self-assembly and non-solvent induced phase separation (SNIPS) is challenging, and only few works were conducted until now. Herein, we described that membranes with pore size down to 8.6 nm…
A Translucent Nanocomposite with Liquid Inclusions of a Responsive Nanoparticle Dispersion
Doblas, David; Hubertus, Jonas; Kister, Thomas; Kraus, Tobias
Active nanocomposites are created with liquid inclusions that contain plasmonic gold nanoparticles inside a polymeric matrix. The alkylthiol-coated gold particles are designed to reversible agglomerate at certain temperatures, which changes the plasmonic coupling and thus optical properties. It is found that particles confined to the liquid inclusions inside the active…
Grafted polyrotaxanes as highly conductive electrolytes for lithium metal batteries
Imholt, Laura; Dörr, Tobias S.; Zhang, Peng; Ibing, Lukas; Cekic-Laskovic, Isidora; Winter, Martin; Brunklaus, Gunther
Hyperbranched polymers comprised of polyrotaxanes as mechanically stable backbone and grafted polycaprolactone (PCL) side chains are utilized as solid polymer electrolyte for application in lithium metal (LMBs) and lithium ion batteries (LIBs). The polyrotaxanes were obtained from self-assembly of Cyclodextrin (CD) host molecules threading onto polyethylenoxide (PEO) chains. In particular,…
Thermo-chemically tuning of active basic sites on nanoarchitectured silica for biodiesel production
Sánchez Faba, Edgar M.; Ferrero, Gabriel O.; Dias, Joana M.; Eimer, Griselda A.
In the design of catalysts, an extremely important point is to determine, control and increase the availability of active sites on the surface. In the present work, active sodium oxide species have been identified and it is demonstrated how its dispersion can be suitably improved by combining sodium loading degree…
