Combining Small-Angle X-ray Scattering and X-ray Powder Diffraction to Investigate Size, Shape and Crystallinity of Silver, Gold and Alloyed Silver-Gold Nanoparticles

Garcia, P. R. A. F.; Loza, K.; Daumann, S.; Grasmik, V.; Pappert, K.; Rostek, A.; Helmlinger, J.; Prymak, O.; Heggen, M.; Epple, M.; Oliveira, C. L. P.

The combination of simultaneous measurements of small and wide angle X-ray scattering (SAXS/WAXS–SWAXS) to investigate the overall size, shape, and crystallinity of silver nanoparticles and alloyed silver-gold nanoparticles in the size range of 8 to 80 nm is shown. The obtained results for overall size are in agreement with the…

Partial Transformation of Imogolite by Decylphosphonic Acid Yields an Interface Active Composite Material

Lange, Tobias; Charpentier, Thibault; Gobeaux, Frédéric; Charton, Sophie; Testard, Fabienne; Thill, Antoine

The phosphonic acid moiety is commonly used as an anchoring group for the surface modification of imogolite. However, the impact of the reaction on its structure has never been clearly analyzed before. We study the reaction of imogolite and decylphosphonic acid by combining infrared spectroscopy, X-ray scattering, scanning electron microscopy,…

3D visualisation of hepatitis B vaccine in the oral delivery vehicle SBA-15

Rasmussen, Martin K.; Kardjilov, Nikolay; Oliveira, Cristiano L. P.; Watts, Benjamin; Villanova, Julie; Botosso, Viviane Fongaro; Sant’Anna, Osvaldo A.; Fantini, Marcia C. A.; Bordallo, Heloisa N.

Developing a technology that enables oral vaccines to work efficiently remains a considerable effort since a number of difficulties must be addressed. The key objective being to ensure the safe passage through the harsh conditions within the gastrointestinal tract, promoting delivery that induces enhanced immune response. In the particular case…

Simultaneous SAXS-WAXS Experiments on Semi-Crystalline Polymers: Example of PA11 and Its Brill Transition

Tencé-Girault, Sylvie; Lebreton, Sylvie; Bunau, Oana; Dang, Patrick; Bargain, François

This manuscript of the special issue “Microstructural Evolution and Mechanical Behavior of Semi-Crystalline Polymers” aims to show that Small Angle X-ray Scattering (SAXS) and Wide Angle X-ray Scattering (WAXS) experiments performed simultaneously constitute a unique tool to obtain valuable information on the hierarchical structure of semi-crystalline polymers. These structural quantitative…

Formation and evolution of shish-kebab structure during hot stretching in gel-spun ultra-high molecular weight polyethylene fibers with high concentration gel solution

An, Minfang; Lv, You; Xu, Haojun; Li, Yiguo; Wang, Zongbao

Formation and evolution of shish‐kebab crystals of gel‐spun ultra‐high molecular weight polyethylene fibers from high concentration gel solution during hot‐stretching process were studied by in situ small‐angle X‐ray scattering and wide‐angle X‐ray diffraction measurements, differential scanning calorimetry, and scanning electron microscopy. We show that the structural evolution process can be…

Effect of solvent-matrix interactions on structures and mechanical properties of micelle-crosslinked gels

Xu, Dan; Xu, Ting; Gao, Guorong; Xiao, Ying; Wang, Zongbao; Chen, Jing; Zhou, Yang; Wang, Rong; Yin, Jingbo; Fu, Jun

Previous studies on hydrogels crosslinked by acrylated PEO99–PPO65–PEO99 triblock copolymer (F127DA) micelles demonstrate outstanding strength and toughness, which is attributed to the efficient energy dissipation through the hydrophobic association in the micelles. The current study further focuses on how the solvent property affects the structures and the mechanical properties of…

Improved thermal conductivity of thermoplastic polyurethane via aligned boron nitride platelets assisted by 3D printing

Liu, Junchao; Li, Weiwei; Guo, Yufeng; Zhang, Hui; Zhang, Zhong

Thermal management is of importance to microelectronics. Owning both excellent thermal conduction and electrical insulation, hexagonal boron nitride (hBN) platelets are widely used in polymer matrices. While the thermal properties rely on the orientation of hBN platelets in polymer matrices significantly. Herein, we report that high thermal conductive hBN filled…

Reactive oxygen species (ROS)-responsive nanomedicine for RNAi-based cancer therapy

Li, Yang; Bai, Hongzhen; Wang, Hebin; Shen, Youqing; Tang, Guping; Ping, Yuan

Although much effort has been dedicated to the development of efficient siRNA delivery for cancer therapy, delivery nanomaterials that can particularly respond to reactive oxygen species (ROS), which are overproduced in the tissue and mitochondria of cancer cells, are still rare for the clinical translation of RNA interference (RNAi)-based therapy.…

High-Efficiency Construction of CO2-Based Healable Thermoplastic Elastomers via a Tandem Synthetic Strategy

Yang, Guan-Wen; Wu, Guang-Peng

The alternating copolymerization of CO2/epoxides to polycarbonates (CO2–PCs) has been an area of research focus because of the growing concern about energy and the environment. Regardless of the enormous progress that has been made, the lack of functionalities and inert chemical structure of CO2-based polycarbonates greatly limit the scope of…

Epsilon-Fe2O3 Nanocrystals inside Mesoporous Silicas with Tailored Morphologies of Rod, Platelet and Donut

Li, Jheng-Guang; Fornasieri, Giulia; Bleuzen, Anne; Gich, Martí; Impéror‐Clerc, Marianne

The ϵ-Fe2O3 polymorph of iron oxide, which has outstanding physical properties, is successfully stabilized inside mesoporous silica particles with tailored shapes. Using mesoporous silica particles with three different morphologies of rod, platelet and donut, we obtain ϵ-Fe2O3/mesoporous silica nanocomposites. Iron oxide is loaded inside the porosity using a two steps…
