Hard–Soft Carbon Composite Anodes with Synergistic Sodium Storage Performance

Xie, Fei; Xu, Zhen; Jensen, Anders C. S.; Au, Heather; Lu, Yaxiang; Araullo‐Peters, Vicente; Drew, Alan J.; Hu, Yong-Sheng; Titirici, Maria-Magdalena

A series of hard–soft carbon composite materials is produced from biomass and oil waste and applied as low-cost anodes for sodium-ion batteries to study the fundamentals behind the dependence of Na storage on their structural features. A good reversible capacity of 282 mAh g−1 is obtained at a current density…

A high-performance BaTiO 3 -grafted-GO-laden poly(ethylene oxide)-based membrane as an electrolyte for all-solid lithium-batteries

Angulakshmi, N.; Prasanna Kar, Goutam; Bose, Suryasarathi; Bhoje Gowd, E.; Thomas, Sabu; Manuel Stephan, A.

Nanocomposite polymer electrolytes (NCPEs) comprising poly(ethylene oxide) (PEO), barium titanate-grafted-graphene oxide (BaTiO3-g-GO) and lithium bis(trifluoromethanesulfonyl imide) (LiTFSI) were prepared by a simple hot-press technique. An increase of two orders of magnitude in the ionic conductivity was achieved upon incorporation of BaTiO3-g-GO in the polymeric matrix even at 0 °C. The…

Tuning the properties of electrospun polylactide mats by ethanol treatment

Pavlova, Elizaveta R.; Bagrov, Dmitry V.; Monakhova, Kristina Z.; Piryazev, Alexey A.; Sokolova, Anastasia I.; Ivanov, Dimitri A.; Klinov, Dmitry V.

In the present work, we analyzed the changes in structure and mechanical properties of electrospun PLA mats induced by ethanol treatment. The amorphous PLA mats gained elasticity when immersed into ethanol (the elongation at break increased from ?~50% in air to ?~280% in ethanol) and partly retained it after drying…

Extending the hydrogen storage limit in fullerene

Gaboardi, Mattia; Sarzi Amadé, Nicola; Aramini, Matteo; Milanese, Chiara; Magnani, Giacomo; Sanna, Samuele; Riccò, Mauro; Pontiroli, Daniele

Li6C60 has been chosen as the most representative system to study the hydrogenation mechanism in alkali-cluster intercalated fullerides. We present here a muon spin relaxation (?SR) experiment that hints the chance to achieve a higher storage capacity on fullerene with respect to the values suggested in literature. Moreover, a linear…

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,…

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 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…

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…
