“…As shown in Figure 3 d). [ 24 ] A highresolution TEM image of the fi ne microstructure shows that these nanosheets have sharp edges and a turbostratic structure ( Figure S10, Supporting Information). Such a 3D interconnected network of porous nanosheets containing many junctions and the open pores provide a good combination of infi ltration rate and surface area, [ 25 ] and are also favorable for mass transfer and charge separation.…”

A macroscopic 3D porous graphitic carbon nitride (g-CN) monolith is prepared by the one-step thermal polymerization of urea inside the framework of a commercial melamine sponge and exhibits improved photocatalytic water-splitting performance for hydrogen evolution compared to g-CN powder due to the 3D porous interconnected network, larger specific surface area, better visible light capture, and superior charge-separation efficiency.

“…Hence the stripes in the samples were ascribed to metallic lithium nanocrystallites. [30,31] It should be mentioned that outside the tube wall, there is a uniform amorphous film with a thickness of about 5-7 nm. That is the so called solid electrolyte interphase (SEI) layer formed by the reduction of the electrolyte.…”

In order to address power and energy demands of mobile electronics and electric cars, Li‐ion technology is urgently being optimized by using alternative materials. This article presents a review of our recent progress dedicated to the anode and cathode materials that have the potential to fulfil the crucial factors of cost, safety, lifetime, durability, power density, and energy density. Nanostructured inorganic compounds have been extensively investigated. Size effects revealed in the storage of lithium through micropores (hard carbon spheres), alloys (Si, SnSb), and conversion reactions (Cr2O3, MnO) are studied. The formation of nano/micro core–shell, dispersed composite, and surface pinning structures can improve their cycling performance. Surface coating on LiCoO2 and LiMn2O4 was found to be an effective way to enhance their thermal and chemical stability and the mechanisms are discussed. Theoretical simulations and experiments on LiFePO4 reveal that alkali metal ions and nitrogen doping into the LiFePO4 lattice are possible approaches to increase its electronic conductivity and does not block transport of lithium ion along the 1D channel.

“…Light emission has been reported from carbon nanotubes (CNTs) as nanometersized filaments [1,2] and from boron carbonitride fibres. [3] CNTs have also been used as a carrier by doping Eu or Eu compounds on the nanotube external surfaces, [4,5] but in these cases CNTs are not involved in the light emission. Wide-bandgap semiconductors doped with rare-earth ions are considered as a new type of luminescent material, combining special wide-bandgap semiconducting properties with the rare-earth luminescence feature.…”
