Enhancing Propylene Glycol Product Yield by Modifying the Glycerol Hydrogenation Process
Journal of Chemical Engineering Research ProgressThe production of propylene glycol from glycerol is an emerging and sustainable approach in the chemical industry that can be considered completely renewable. Glycerol, a byproduct of biodiesel production, has gained attention as an alternative feedstock

A vapor generator for transonic flow visualization [PDF]
A vapor generator was developed for use in the NASA Langley Transonic Dynamics Tunnel (TDT). Propylene glycol was used as the vapor material. The vapor generator system was evaluated in a laboratory setting and then used in the TDT as part of a laser ...

Carbon and Hydrogen, EarlyView.This work employs density functional theory (DFT) calculations to identify the reaction mechanism and unveil the roles of Ti species and solvent in propylene epoxidation with H2O2 over TS‐1 catalyst. ABSTRACT The mechanism of propylene epoxidation catalyzed by distinct titanium (Ti) species within the TS‐1 framework was systematically explored through ...

Picosecond Dynamic Heterogeneity, Hopping and Johari-Goldstein Relaxation in Glassforming Liquids
, 2014 We show that incoherent quasi-elastic neutron scattering (QENS) from molecular liquids reveals a two-state dynamic heterogeneity on a 1 ps timescale, where molecules are either highly confined or are free to undergo relatively large excursions.

Carbon Energy, EarlyView.This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work

On the mechanism of the highly viscous flow
, 2011 The asymmetry model for the highly viscous flow postulates thermally activated jumps from a practically undistorted ground state to strongly distorted, but stable structures, with a pronounced Eshelby backstress from the distorted surroundings.

Dual‐Field Synergistic Orientation of Carbon Fibers for High‐Efficiency Thermal Management
Carbon Energy, EarlyView.The sample fabricated by synergistically combining reversed electric and low magnetic fields, with photocurable PEG/PPG gel serving as the matrix, exhibits excellent machinability and flexibility. Meanwhile, the thermal conductivity enhancement efficiency of this work is 1351%, significantly superior to similar carbon fiber composite materials ...
