Energy and nutrients, or chemicals, flow through an ecosystem. While energy flows through the ecosystem and cannot be recycled, nutrients cycle within an ecosystem and are reused. Both energy flow and chemical cycling help define the structure and dynamics of the ecosystem. Primary Producers Primary...

Food webs describe the network of linkages that are responsible for transfers of energy among species, and for the movement of nutrients between organisms and the abiotic environment. Food web networks ideally describe all interactions within a community of species, while recognizing that much of the...
Moreover, the cathode also shows the excellent cycling stability with 92%capacity retention after 3,000 cycles. In addition, a hybrid supercapacitor (HSC) is assembled with the obtained Li2-Ni3Se2 as the cathode and active carbon (AC) as the anode, which delivers a high energy den-sity ...
Here we systematically investi-gated the morphological, structural, and chemical changes of P2-NNMO during high-voltage cycling using a variety of characterization techniques. It was found that the lattice distortion and crystal-plane buckling induced by the P2-O2 phase transition slowed down the ...
Solubility determines energy density in redox flow batteries. Here, authors combine automated experiments with machine learning to efficiently identify solvents that significantly enhance solubility, testing less than 10% of over 2000 candidates.
and cycling performance of Zn@ILDO//MnO2 full batteries and Zn@ILDO//activated carbon zinc-ion hybrid capacitors. This simple and effective dual-function protective layer strategy offers a promising approach for achieving high-performance zinc-ion batteries. ...
The osmotic pressure difference between river water and seawater is a promising source of renewable energy. However, current osmotic energy conversion processes show limited power output, mainly owing to the low performance of commercial ion-exchange membranes. Nanofluidic channels with tailored ion transp...
As an alternative to tackle this last concern, carbon materials have been recently used, due to their good electrical and thermal conductivity, and chemical stability, which makes them one of the most promising materials to replace metallic counter electrodes in the fabrication of PSCs. This ...
We have already confirmed that this theory can be applied to the compression type refrigerator, absorption refrigerator, desiccant air conditioning system and so on. Then, based on this theory, we have developed the general-purpose energy system analysis software that is called Energy Flow +M . ...
