TL;DR: It is demonstrated that plentiful sulfur vacancy (Vs) defects and nanosized heterojunctions are created on the NG/SnS2/TiO2 composite as proved using electron paramagnetic resonance, transmission electron microscopy and X-ray photoelectron spectroscopy, which can serve as strong adsorption and activation sites for polar polysulfide intermediates, prevent their dissolution/shuttling, and accelerate their redox reaction.

TL;DR: In this paper, oxygen-deficient titanium dioxide (TiO2) has been investigated as a novel functional host for Li-S batteries, and the resulting TiO2/S composite cathode manifests superior electrochemical properties in terms of high capacity (1472 mA h g−1 at 0.2C), outstanding rate capability (571 m A h g −1 at 2C), and excellent cycling properties.

TL;DR: In this paper, an experimental study was conducted on a four-cylinder diesel engine added with 0, 10% and 30% 2,5-dimethylfuran (DMF) and the combustion characteristic, nitric oxide (NOx) and particulate matter (PM) emissions under different fuel injection timing were measured and well discussed, especially the particle size distribution, particle number and mass concentration.

TL;DR: In this article, the effects of diesel/gasoline/iso-butanol blends, including pure diesel (D100), diesel (70%), diesel(70%), gasoline (15%), diesel (30%), isobutanol (30%) and diesel (40%), on combustion and exhaust pollutant emissions characteristics in a four-cylinder diesel engine were experimentally investigated under various engine load conditions with a constant speed of 1800rpm.

TL;DR: Molecular chirality is introduced at liquid-solid interfaces and D- or L-NIBC on the surface can guide parallel or nonparallel alignment of β-hairpins through a two-step process based on electrostatic-interaction-enhanced adsorption and subsequent stereoselective recognition.
