Lithium metal, distinguished by its low reduction potential and high theoretical capacity, is regarded as the optimal choice for the next generation of anode materials.

The creation of efficient photocatalysts for hydrogen production is a key strategy in tackling the fossil energy crisis. ZnIn2S4 shows potential as a photocatalyst, yet its practical use in photocatalysis is hindered by the swift recombination of electron-hole pairs.

The introduction of Na2ZrCl6 results in a reduction in the crystallinity of PAN, which

Silicone elastomer exhibits superior cold and heat resistant properties compared to all other elastomers, and is widely used in aerospace, electronic appliances and other fields. However, it is prone to crystallize and even become brittle at temperatures below -50 °C, thereby diminishing its cold resistance performance. Besides, the low mechanical strength of silicone elastomer is also a fatal defect

Although bulk heterojunction (BHJ) structure ensures high power conversion efficiencies (PCEs) of organic solar cells (OSCs), the morphology of this donor:acceptor blend film is thermally unstable due to molecular diffusion of two components, especially small molecule acceptor (SMA).
