Continuous, high-throughput production of artemisinin-loaded supramolecular cochleates using simple off-the-shelf flow focusing device

Shuddhodana; Wong, Pooi Wen Kathy; Judeh, Zaher

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…

Microwave-Assisted Synthesis of Ultrasmall Zinc Oxide Nanoparticles

Saloga, Patrick E. J.; Thünemann, Andreas F.

We report on ultrasmall zinc oxide single-crystalline nanoparticles of narrow size distribution and long-term colloidal stability. These oleate-stabilized nanoparticles were synthesized using microwave-assisted synthesis for 5 min, corresponding to a 99% decrease in synthesis time, when compared to the conventional synthesis method. It was observed that the average particle radius…

A robust expectation-maximization method for the interpretation of small-angle scattering data from dense nanoparticle samples

Bakry, M.; Haddar, H.; Bun?u, O.

A robust method is presented for the resolution of small-angle scattering problems featuring a structure factor. It is based on the local monodisperse approximation and the expectation-maximization…

Harnessing Heat Beyond 200 °C from Unconcentrated Sunlight with Nonevacuated Transparent Aerogels

Zhao, Lin; Bhatia, Bikram; Yang, Sungwoo; Strobach, Elise; Weinstein, Lee A.; Cooper, Thomas A.; Chen, Gang; Wang, Evelyn N.

Heat at intermediate temperatures (120-220 °C) is in significant demand in both industrial and domestic sectors for applications such as water and space heating, steam generation, sterilization, and other industrial processes. Harnessing heat from solar energy at these temperatures, however, requires costly optical and mechanical components to concentrate the dilute…

Controlling Crystal Texture in Programmable Atom Equivalent Thin Films

Gabrys, Paul A.; Macfarlane, Robert J.

DNA is a powerful tool in the directed assembly of nanoparticle based superlattice materials, as the predictable nature of Watson–Crick base pairing allows DNA-grafted particles to be programmably assembled into unit cells that arise from the complete control of nanoparticle coordination environment within the lattice. However, while the local environment…

Synergistic effects from super-small sized TiO2 and SiOx nanoparticles within TiO2/SiOx/carbon nanohybrid lithium-ion battery anode

Wang, Xiaoyan; Xia, Yonggao; Zuo, Xiuxia; Schaper, Simon J.; Yin, Shanshan; Ji, Qing; Liang, Suzhe; Yang, Zhaohui; Xia, Senlin; Xiao, Ying; Zhu, Jin; Müller-Buschbaum, Peter; Cheng, Ya-Jun

TiO2/SiOx/carbon nanohybrid consisting of super-small sized TiO2 and SiOx nanoparticles is in situ formed within the in situ formed carbon matrix using difunctional methacrylate monomers as solvent and carbon source. The relative composition of TiO2 and SiOx is systematically tuned by varying the feeding mass ratio of the precursors (TEOS/TTIP)…

Shape modulation of squaramide-based supramolecular polymer nanoparticles

Talens, Victorio Saez; Makurat, D. M. M.; Liu, Tingxian; Dai, Wei; Guibert, Clément; Noteborn, Willem E. M.; Voets, Ilja K.; Kieltyka, Roxanne E.

We report the synthesis and self-assembly of a library of squaramide-based bolaamphiphiles with variable hydrophobic and hydrophilic domain sizes, consisting of varied aliphatic chains (n = 2 to 12 methylene repeat units) and linear oligo(ethylene glycol) (m = 11 to 36 repeat units), to understand their effect on the formation…

CO2 capture using three-dimensionally ordered micromesoporous carbon

Vorokhta, Maryna; Morávková, Jaroslava; ?imná?ová, Daniela; Pila?, Radim; Zhigunov, Alexander; Švábová, Martina; Sazama, Petr

Adsorption of CO2 on three-dimensionally ordered micromesoporous carbon with a spherical pore structure has been studied using gravimetric and manometric analyses. Adsorptive properties were compared with activated carbon and nanostructured carbon materials such as carbon nanotubes, zeolitic-imidazolate framework-derived carbon, carbon nanohorns and ordered mesoporous carbon materials. The…

Understanding the Static Interfacial Polymer Layer by Exploring the Dispersion States of Nanocomposites

Genix, Anne-Caroline; Bocharova, Vera; Carroll, Bobby; Lehmann, Michelle; Saito, Tomonori; Krueger, Susan; He, Lilin; Dieudonné-George, Philippe; Sokolov, Alexei P.; Oberdisse, Julian

The dynamic and static properties of the interfacial region between polymer and nanoparticles have wide-ranging consequences on performances of nanomaterials. The thickness and density of the static layer are particularly difficult to assess experimentally due to superimposing nanoparticle interactions. Here, we tune the dispersion of silica nanoparticles in nanocomposites by…
