A Close Look at Lithium Batteries

Fluorescence probe shows the distribution of active lithium species on lithium metal anodes

29-Apr-2019

Batteries with metallic lithium anodes offer enhanced efficiency compared to conventional lithium-ion batteries because of their higher capacity. However, safety concerns and a short lifespan stand in the way. To better analyze the causes of malfunctions and premature failure of such batteries, ...

Boron can form a purely honeycomb, graphene-like 2-D structure

16-Mar-2018

Seeking for low-dimensional boron allotropes has attracted considerable interest in the past decades and tremendous theoretical works predict the existence of monolayer boron. As boron has only three valence electrons, the electron deficiency makes a honeycomb lattice of boron energetically ...

Factors in the fabrication of heterojunctions of 2D-materials through CVD

14-Nov-2017

2D-materials have special lattice structures. Atoms in the same layer were usually bound by the covalent bond, while the force between layers is van der Waals coupling. They have super clean surfaces without any dangling bonds. Thus, the design of heterojunctions will be flexible when ...

An efficient multifunctional catalyst for CO2 hydrogenation to gasoline

04-May-2017

Converting CO2 from a detrimental greenhouse gas into value-added liquid fuels not only contributes to mitigating CO2 emissions, but also reduces dependence on petrochemicals. However, since CO2 is a fully oxidized, thermodynamically stable and chemically inert molecule, the activation of CO2 and ...
