Sodium-ion batteries (SIBs) are utilized as a promising alternative to commercial lithium-ion (LIBs) where hard carbons (HCs) anticipated be the first commercially available anode material for SIBs. Among various carbon precursors, wood accounts more than 30% of global land cover, making it one most abundant sources biomass materials on planet. In addition superior renewability, sustainability and biodegradability, its derivatives still possess some unique advantages such anisotropic graded...
An original cationic water-soluble cyclen-based Eu(III) complex [EuL1]+ featuring a chromophore-functionalized antenna to increase the two-photon (2P) absorption properties was synthesized. The photophysical were thoroughly studied in various solvents and rationalized with help of theoretical calculations. exhibits an optimized 2P cross section. Finally, microscopy imaging experiments on living T24 human cancer cells highlighted spontaneous internalization biological stability this bioprobe...
Dyes emitting in the solid state red or near-infrared range are much sought after for application bioimaging especially if long emission wavelength can be combined with two-photon excitation to provide unique contrast and penetration depth.
Abstract Microcapsules with a liquid core and solid shell composed of hydrophobic nanoparticles are broadly applied in food, pharmaceutics, biotechnologies. For example, Pickering emulsions, colloidosomes, or antibubbles (droplets surrounded by air layers water) enable controlled release active agents, biocompatibility, contact‐less transportation. However, producing nanoparticle‐ polymer‐laden shells at scale is highly challenging, since bulk methods polydisperse microfluidic chips prone to...
Abstract Fast mixing of small volumes solutions in microfluidic devices is essential for an accurate control and observation the dynamics a reaction biological or chemical studies. It often, however, challenging task, as Reynolds number ( Re ) microscopic typically < 100. In this report, we detail novel mixer based on “staggered herring bone” (SHB) pattern “split-recombination” strategies with optimized geometry, periodic rotation flow structure can be controlled recombined way that...
Multi-shelled ceria hollow spheres with tunable shell number and thickness have been prepared <italic>via</italic> a coordination polymer precursor method. Besides, this method was extended to the preparation of other rare earth oxides. Au AuPd loaded composites display superior catalytic activity.
Hybrid imogolite aluminosilicate nanotubes with methylated internal surface can be obtained by introduction of the corresponding organosilane during their synthesis. However, similarly to pristine imogolite, a number side products, including proto-imogolite (open-imoLS), allophanes, and aluminum hydroxides, are formed, which ultimately impact on properties dispersions. In order minimize proportion these we have here systematically explored initial Si/Al ratio content hybrid dispersions...
Imogolite forms a class of inorganic nanotubes whose inner and outer surfaces can be tuned on molecular level. The combination this property with their monodisperse diameters makes imogolites ideal to study water confinement in one-dimensional environment. Here, we have investigated, by means infrared (IR) spectroscopy, confined two types germanium-based imogolites: (i) the hydroxylated imogolite (Ge-IMO-OH), double-walled structure an interstitial space about 2 Å interior tube covered Ge–OH...

Layered double hydroxides (LDHs) are adsorbent materials able to store significant amounts of anionic radionuclides under various levels hydrations. In view this storage application, it is crucial understand their evolution ionizing radiation, particularly as a function hydration state. We thus synthesized four LDHs, with Mg/Al molar ratio ∼3.5 and different anions: NO3–, CO32–, ClO4–, Cl– chosen for contrasted behavior toward radiation. For all these materials, the initial interlamellar...
