چکیده
To follow up on the performance of lithium-ion batteries (LIBs), transition metal sulfides (TMSs) have been developed as promising carbon alternatives for sodium-ion (SIBs). Although attractive, it is still a great challenge to fulfill their capacity utilization with high cycling performance. Herein, nanoemulsion-directed method has control spherical arrangement [email protected] units both penetrating macropores from center surface and inner mesopores distributed among bulks. With respect ion diffusion, could serve built-in ion-buffer reservoirs keep steady flow electrolyte, while facilitate diffusion across whole In terms stability, radical porous structure work self-supported vertical bones accommodate volume change lateral sides. Besides, localized ZnS nanoparticles not only acts binding agents join numerous but also endows effective electron transmission capability. As proof concept, such hydrangea-like nanospheres deliver sodium storage high-rate long-cycling This approach anticipated other TMSs pores post-lithium-ion applications.

Communication between the nucleus and cytoplasm occurs through large macromolecular structures, the nuclear pores. Quantitative scanning transmission electron microscopy has estimated the mass of a nuclear pore to be 60 million Daltons in yeast and 120 million Daltons in vertebrates. The past two years were noteworthy in that they saw: 1) the purification of both the yeast and vertebrate nuclea...
متن کامل3D hierarchical porous graphene aerogel with tunable meso-pores on graphene nanosheets for high-performance energy storage
New and novel 3D hierarchical porous graphene aerogels (HPGA) with uniform and tunable meso-pores (e.g., 21 and 53 nm) on graphene nanosheets (GNS) were prepared by a hydrothermal self-assembly process and an in-situ carbothermal reaction. The size and distribution of the meso-pores on the individual GNS were uniform and could be tuned by controlling the sizes of the Co3O4 NPs used in the hydro...

Synthesis and assembly of core/shell nanospheres.
In this paper, we reported a new simple and effective method, osmotic membrane-assisted self-assembly, for fabricating massive interconnected macroporous silica monolith as catalyst supports. Using the method, we can prepare massive interconnected macroporous silica monolith with homogeneous structures beyond millimeter scale one time. Typically, silica/polystyrene and polystyrene/poly 4-vinyl ...
