Engineering Mechanically Adaptive Nanonetworks for Long‐Life and High‐Capacity Silicon Anode Batteries

Carbon Energy, EarlyView.
ABSTRACT Silicon anodes, with a theoretical capacity of ~ $\unicode{x0007E}$3860 mAh g−1, offer more than ten times the lithium storage of graphite but suffer from large volume expansion during lithiation, leading to particle fracture, electrical disconnection, and unstable solid–electrolyte interphases (SEIs).

A behavior‐based framework for assessing barrier effects to wildlife from vehicle traffic volume

Ecosphere, 2016
Roads, while central to the function of human society, create barriers to animal movement through collisions and habitat fragmentation. Barriers to animal movement affect the evolution and trajectory of populations.

Unlocking Thermodynamic‐Kinetic Synergy via Rh/Co Dual Sites and Ordered Interfacial Hydrogen‐Bond Network for Efficient Biomass Electrooxidation

Carbon Energy, EarlyView.
An amorphous RhOx‐decorated cobalt‐deficient Co3O4 catalyst is designed for efficient HMF electro‐oxidation to FDCA. This design enables Rh/Co dual sites for enhanced HMF/OH− adsorption thermodynamics while independently ordering interfacial water into a connected hydrogen‐bond network that accelerates proton transfer kinetics, delivering outstanding ...

Electrospun Porous Materials for the Next‐Generation Proton Exchange Membrane Fuel Cells: Progress, Challenges, and AI‐Optimized Perspectives

Carbon Energy, EarlyView.
Incorporating AI to optimize solution, process, and environment enables efficient prediction of structural properties and performance, allowing tailoring of GDL, CL, and PEM fabrication to guide PEMFC toward 9.0 kW L‒1 by 2040. ABSTRACT The performance and commercial viability of proton exchange membrane fuel cells (PEMFCs) are constrained by key ...

Sparse maximum likelihood estimation of regression models

Canadian Journal of Statistics, EarlyView.
Abstract For regression model selection and estimation, we study a small set of candidate models of maximum likelihood from which all information criteria such as the Akaike information criterion (AIC) and the Bayesian information criterion (BIC) choose their models.

Captivated by Kinesin

Cytoskeleton, EarlyView.
ABSTRACT Few proteins have inspired as much curiosity as kinesin. Since its discovery 40 years ago, kinesin has become one of the best understood molecular machines in biology, yet it continues to reveal new questions about how cells organize and move their contents.
