TL;DR: A uniform amorphous carbon coating on the tin nanoparticles was prepared from aqueous glucose solutions using a hydrothermal method at 180 °C, which facilitated an enhanced dimensional stability during Li alloying/dealloying as mentioned in this paper.
Abstract: A uniform amorphous carbon coating on the tin nanoparticles was prepared from aqueous glucose solutions using a hydrothermal method at 180 °C, which facilitated an enhanced dimensional stability during Li alloying/dealloying. This material showed excellent initial capacity and capacity retention, 681 mAh/g and 98% retention after 50 cycles, respectively.

TL;DR: In this paper, the shape and properties of 30 Zintl ions [E9] are analyzed and a close relationship exists between the compounds with anionic nine-atom clusters of elements of the carbon group and the superconducting fulleride salts, which contain negatively charged polyhedra of the lightest element in this group.

TL;DR: It is shown that the use of large terphenyl substituents allows the isolation of transition metal-heavier group 14 element complexes that can achieve essential triple bonding by a three-fold orbital interaction between the transition metal and group 14 moiety.

TL;DR: In this article, the transmission infra-red technique has been used to investigate the surface of tin(IV) oxide as a function of evacuation temperature in the range 293-773 K.
Abstract: The transmission infra-red technique has been used to investigate the surface of tin(IV) oxide as a function of evacuation temperature in the range 293–773 K. Molecular water is largely removed by evacuation at 320 K and is fully removed at 473 K. Hydrogen-bonded hydroxyl groups are present after evacuation at 773 K, and isolated hydroxyl groups exhibit a stretching frequency at 3640 cm–1. Room temperature carbon dioxide adsorption has been studied as a function of thermal pretreatment in the range 320–618 K and the spectra obtained indicate a surface carbonate and a surface bicarbonate. The adsorption of carbon monoxide has been investigated in a similar manner. A carbonate species is proposed from the infra-red data, and the partial reduction of the tin(IV) oxide to a tin(II) species has been confirmed by tin-119 m Mossbauer spectroscopy. No evidence was obtained for the physical adsorption of either carbon dioxide or carbon monoxide.
