A Perspective on Pathways Toward Commercial Sodium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
Comprehensive analysis of the existing and prospective sodium‐ion battery (SIB) systems unveils that a wider application of SIBs should primarily focus on i) regulating the composition, morphology, surface chemistry, safety performance, and production feasibility of mainstream cathodes, ii) enhancing the high‐voltage stability, film formation ability ...

Optimal portfolio selection in an Itô-Markov additive market [PDF]

open access: yesarXiv, 2018
We study a portfolio selection problem in a continuous-time It\^o-Markov additive market with prices of financial assets described by Markov additive processes which combine L\'evy processes and regime switching models. Thus the model takes into account two sources of risk: the jump diffusion risk and the regime switching risk.

Facet‐Controlled Growth of Molybdenum Phosphide Single Crystals for Efficient Hydrogen Peroxide Synthesis

open access: yesAdvanced Materials, EarlyView.
Facet‐controlled growth of molybdenum phosphide single crystals via liquid‐metal‐assisted chemical vapor deposition, demonstrating MoP nanoplate and pillar morphologies formed at different temperatures for efficient hydrogen peroxide synthesis. Abstract Transition metal phosphides (TMPs) stand out for their excellent catalytic activity, driven by metal‒

Full Wafer Scale Manufacturing of Directly Printed TiO2 Metalenses at Visible Wavelengths with Outstanding Focusing Efficiencies

open access: yesAdvanced Materials, EarlyView.
The highest experimentally determined focusing efficiency is reported here by using the direct imprinting of all‐inorganic TiO2 metalens arrays. Absolute efficiency greater than 80% and relative efficiency greater than 90% are achieved by optimization of all fabrication parameters controllable in the additive manufacturing process.

Network Effects on Platform Markets. Revisiting the Theoretical Literature

open access: yesScientific Annals of Economics and Business
The characteristics of the bilateral network markets were already studied before 2003, but they focused on specific markets (credit cards or newspaper advertising) without relating implications with third parties.
