In this work, quasi two dimensional spinel ZnCo2O4 (ZCO) nanosheets constituted by ZCO grain with different size were prepared via a facile solvothermal method and followed by a post-treatment. It shows that the small ZCO grain can be obtained by a fast cooling post-treatment. Further, to enhance the conductivity of ZCO, uniform and compact ZCO nanosheets was in-situ grown on reduced graphene oxide (rGO), which was employed as template. When used as anode for lithium ions battery (LIB), rGO@ZCO has a large reversible capacity of 1107.2 mAh·g-1 at 100 mA·g-1 after 100 cycling, which is the highest among all ZCO samples. Moreover, when the current density is from 50 to 500 mA·g-1, the capacity of rGO@ZCO decreased from 1046.5 to 527.6 mAh·g-1, implying the superior rate ability. The electrochemical analysis together with calculations demonstrates that the unique structure is beneficial to promote the charge transport and adapt the volume change in charge-discharge process, resulting in expected LIB performance.

Nanoparticles and two-dimensional (2D) nanosheets are well investigated as lubricant additives, which can significantly reduce frictional energy consumption. However, the tribological properties of th...
Two-dimensional (2D) materials have been widely studied and used as anode material for lithium ion battery because of their high specific surface areas and intrinsic mechanical flexibility which could...
It is highly essential but challengeable to explore the earth-abundant and low-cost oxygen evolution reaction catalysts to replace Ir- or/and Ru-based ones. In this article, we report an in situ growt...
An amperometric method for hydrazine detection is described that is based on the use of electrochemically reduced graphene oxide (ERGO) that was modified with Pt-Pd nanoparticles. A glassy carbon elec...
Nanoparticles (NPs) are minute pieces of material to which we are exposed every day in the air we breathe. Some are naturally occurring and have no impact on health, whereas others are pro...
the aim of the study is to establish reference data that could be used for the creation of more accurate three dimensional prediction of soft tissue outcome.
The overall objective of this clinical study is to determine if smokers who switch from their usual high reactive oxygen and nitrous oxide species (ROS/NOS) products to a low ROS/NOS produ...
The purpose of this study is to test the effectiveness of USES, a strengths-based enhancement to supported employment (SE), as compared to supported employment alone.
Lack of depth perception and spatial orientation are drawbacks of laparoscopic surgery. The advent of the three-dimensional (3D) camera system enables surgeons to regain binocular vision. ...
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
