The NCEP Climate Forecast System Reanalysis (CFSR) was completed for the 31-yr period from 1979 to 2009, in January 2010. CFSR designed and executed as a global, high-resolution coupled atmosphere–ocean–land surface–sea ice system provide best estimate of state these domains over this period. current will be extended an operational, real-time product into future. New features include 1) coupling atmosphere ocean during generation 6-h guess field, 2) interactive sea model, 3) assimilation...
The second version of the NCEP Climate Forecast System (CFSv2) was made operational at in March 2011. This has upgrades to nearly all aspects data assimilation and forecast model components system. A coupled reanalysis over a 32-yr period (1979–2010), which provided initial conditions carry out comprehensive reforecast 29 years (1982–2010). done obtain consistent stable calibrations, as well skill estimates for subseasonal seasonal predictions with CFSv2. implementation full system ensures...
Abstract Rechargeable lithium batteries using 5 V positive electrode materials can deliver considerably higher energy density as compared to state-of-the-art lithium-ion batteries. However, their development remains plagued by the lack of electrolytes with concurrent anodic stability and Li metal compatibility. Here we report a new electrolyte based on dimethyl 2,5-dioxahexanedioate solvent for V-class Benefiting from particular chemical structure, weak interaction cation resultant peculiar...
Eliminating the use of critical metals in cathode materials can accelerate global adoption rechargeable lithium-ion batteries. Organic materials, derived entirely from earth-abundant elements, are principle ideal alternatives but have not yet challenged inorganic cathodes due to poor conductivity, low practical storage capacity, or cyclability. Here, we describe a layered organic electrode material whose high electrical and complete insolubility enable reversible intercalation Li+ ions,...
Metal–organic frameworks (MOFs) have emerged as an important, yet highly challenging class of electrochemical energy storage materials. The chemical principles for electroactive MOFs remain, however, poorly explored because precise and structural control is mandatory. For instance, no anionic MOF with a lithium cation reservoir reversible redox (like conventional Li-ion cathode) has been synthesized to date. Herein, we report on electrically conducting cathodes the generic formula...
The organic metal-ion battery field remains challenged by the lack of high-voltage alkali-cation reservoir cathode materials. Whereas a few recent breakthroughs provided valuable solutions for Li-ion storage, Na-ion and K-ion reservoirs with high voltage ambient stability remain elusive.

Two-dimensional conductive metal-organic frameworks (2D cMOFs) are an emerging class of crystalline van der Waals layered materials with tunable porosity and high electrical conductivity. They have been used in a variety applications, such as energy storage conversion, chemiresistive sensing, quantum information. Although designing new 2D cMOFs studying their composition/structure-property relationships attracted significant attention, there still very few examples that exhibit...
High contact ratio gears have been demonstrated to provide significant advantages for decreasing tooth root and stresses with potential flow-on benefits increased load carrying capacity. Previous investigations high involved analytical, numerical experimental aspects. Much of the earlier work using FEA was limited in its usefulness due several factors; (i) difficulty predicting sharing over roll angles covering two or three teeth simultaneously mesh, (ii) analysis obtain quality results when...
Silicon is regarded as one of the most promising anode candidates for next-generation Li-ion batteries because its high theoretical capacity (4200 mAh g−1). However, main challenge practical application Si anodes huge volume change during (de)alloying with lithium, which leads to pulverization active material and severe loss electrical contact after cycling.
