Although lithium-ion batteries are traditionally considered to be the most promising candidate for electrochemical energy storage owing to their relatively long cycle life and high energy efficiency, their limited energy density as well as high cost are still causing a bottleneck for their long-term applications. Alternatively, rechargeable Li-O2 batteries have the potential to practically prov...

High-temperature oxidation of silicon-carbide nanoparticles (nSiC) underlies a wide range of technologies from high-power electronic switches for efficient electrical grid and thermal protection of space vehicles to self-healing ceramic nanocomposites. Here, multimillion-atom reactive molecular dynamics simulations validated by ab initio quantum molecular dynamics simulations predict unexpected...

Abstract This work combines hydrophobic and heat-absorbing materials to solve the problem of water frost resistance in industrial domestic scenarios harsh environments. Here, highly fast endothermic (HHFE) surfaces were prepared by applying candle soot (nanocarbon) as template, slides carrier nano-TiO2 a backbone connecting layer. The resulting HHFE surface exhibited coral-like porous structure...

Carbon nanospheres (CNSs) and multi-walled carbon nanotubes (MWCNTs) as nanoadditives were used to modify lithium hydroxide monohydrate for low temperature chemical heat storage application. The lithium hydroxide monohydrate particles were well dispersed on the nanoscale level, and the diameter of nanoparticles was about 20–30 nm in the case of the carbon nanospheres and 50–100 nm the case of t...

Chemical charging of single-walled carbon nanotubes (SWCNTs) and graphenes to generate soluble salts shows great promise as a processing route for electronic applications, but raises fundamental questions. The reduction potentials of highly-charged nanocarbon polyelectrolyte ions were investigated by considering their chemical reactivity towards metal salts/complexes in forming metal nanopartic...

Motivated by the rapid development of portable electronics, electric vehicles (EVs), and renewable energy harvesting, advanced materials with exceptional electrical, thermal, chemical, and mechanical properties for energy storage devices featuring good flexibility, high power and energy densities, and low cost are highly sought after. With the rapid growth of nanotechnology (nanotech), two typi...

We analyze the definition of the Gibbs free energy of a nanoparticle in a reactive fluid environment, and propose an approach for predicting the size of carbon nanoparticles produced by the detonation of carbon-rich explosives that regards their condensation as a nucleation process and takes into account absolute entropy effects of the cluster population. The results are consistent with experim...
