Carbon Energy, EarlyView.Origin of the ultrahigh‐rate charge capability of FeS2: FeS2 demonstrates exceptional high‐rate charging capability, delivering 92% capacity retention at 10 C and maintaining as much as 60% capacity retention even at 30 C. This originates from an ultrahigh apparent diffusion coefficient involving both Li+ and Fe2+.

Comparing soil boundaries delineated by digital analysis of multispectral scanner data from high and low spatial resolution systems [PDF]
, 1977 The author has identified the following significant results. Computer-aided analysis techniques used with aircraft MSS data showed that the spatial resolution was sufficient to recognize each soil mapping unit of the test site. Some difficulties occurred

Carbon Energy, EarlyView.An expandable‐thickness graphene block (GPB) with high thermal conductivity synthesized through multiscale blending and multistage pressure induction (MBP) achieves a record thickness of 12.1 mm, which is more than 10 times that of existing graphene materials. The maximum thermal diffusion ability of GPB‐MBP reaches 6.3 W/K, which offers a new approach
