Modulating product selectivity in lignin electroreduction with a robust metallic glass catalyst

Nature Communications
Converting the lignin into value-added chemicals and fuels represents a promising way to upgrade lignin. Here, we present an effective electrocatalytic approach that simultaneously modulates the depolymerization and hydrogenation pathways of lignin model

Scalable Freeze-Tape-Casting Fabrication and Pore Structure Analysis of 3D LLZO Solid-State Electrolytes. [PDF]

, 2020
Nonflammable solid-state electrolytes can potentially address the reliability and energy density limitations of lithium-ion batteries. Garnet-structured oxides such as Li7La3Zr2O12 (LLZO) are some of the most promising candidates for solid-state devices.

Nonequilibrium Thermodynamics of Porous Electrodes

, 2012
We reformulate and extend porous electrode theory for non-ideal active materials, including those capable of phase transformations. Using principles of non-equilibrium thermodynamics, we relate the cell voltage, ionic fluxes, and Faradaic charge-transfer

Quantacell: Powerful charging of quantum batteries

, 2015
We study the problem of charging a quantum battery in finite time. We demonstrate an analytical optimal protocol for the case of a single qubit. Extending this analysis to an array of N qubits, we demonstrate that an N-fold advantage in power per qubit ...

Sulfur Reduction Pathways and Through-thickness Distribution in Positive Composite Electrodes of All-solid-state Li–S Batteries: Elucidation of Two-stage Discharge Plateaus

Electrochemistry
Sulfur positive electrodes in liquid-type lithium–sulfur (Li–S) batteries exhibit two discharge plateaus at approximately 2.4 and 2.1 V (vs. Li). However, conventional sulfur composite electrodes in all-solid-state Li–S batteries typically do not display

Unique compounds functionalized with three-membered cyclic structures

Green Chemical Engineering
Three-membered cyclic compounds are a fascinating class of compounds: they have the maximum torsional and angular strain (sp3 hybridization but bond angles deviate from 109°28’), and possess unique physical and chemical properties.
