Close-up on light red limestone from Morrison, Colorado, a sample set in the NIST stone wall

open access: yes, 2017
The NIST stone wall was built using 2,352 stones from 47 US states and 320 from 16 foreign countries. The wall is approximately 12 m long, 4 m high, 0.6 m thick at the bottom, and 0.3 m at the top. The aim of the wall construction was to study the aging

Multi‐Scale Hybrid Modeling to Predict Cell Culture Process With Metabolic Phase Transitions

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT To advance understanding of cellular metabolism and reduce batch‐to‐batch variability in cell culture processes, this study introduces a multi‐scale hybrid modeling framework designed to simulate and predict the dynamic behavior of CHO cell cultures undergoing metabolic phase transitions.

Insight of Elementary Steps on the Polyethylene and Polypropylene Co‐Pyrolysis

open access: yesCarbon and Hydrogen, EarlyView.
Pyrolysis of PP initiates first, accelerating PE cracking via secondary radical transfer, leading to n‐hydrocarbon yield enhancement. Py–GC/MS and nanoreactor computation are in agreement on the elementary step proposal. ABSTRACT Pyrolysis with gas chromatography & mass spectrometry (Py–GC/MS) technique was employed to analyze the yield variation of ...

Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

open access: yesCarbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Catalyst‐Free Cyanation of Arenes by Acetonitrile in a Plasma–Liquid Microreactor

open access: yesChemistry – A European Journal, EarlyView.
An original approach of arylnitrile synthesis was developed by generating an argon plasma in contact with solutions of arene in acetonitrile within a gas‐liquid microreactor. Plasma activation of acetonitrile generated cyano radicals, enabling a catalyst‐free C‐H cyanation of arenes.

WSPLK: A systematic approach to the thermodynamic characterization of light and heavy Mexican crude oil

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...
