Entropy‐Controlled Exsolution of Highly Dispersed Nickel‐Based Active Metals From Spinel Oxide via Optimizing Metal‐Support Interaction for Dry Reforming of Methane

Carbon Energy, EarlyView.
The incorporation of transition‐metal elements into spinel oxides results in enhanced configurational entropy and increased metal‐support interaction, which continuously modulate the exsolution of nickel‐based active metal. The highly dispersed nickel‐based metal catalyst, formed through the entropy‐controlled strategy, demonstrates remarkable activity

Quantized conductance observed during sintering of silver nanoparticles by intense terahertz pulses

, 2018
We show that silver nanoparticles, which are deposited on a terahertz-receiving antenna, can be sintered by intense terahertz pulse irradiation. The conductance of the silver nanoparticles between the antenna electrodes is measured under the terahertz ...

Revisiting acidulation for tall oil and lignin manufacturing

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production
