Carbon mitigation in the dry reforming of methane

, 2020
Dry reforming of methane is a technique to produce syngas from biogas or CO2-rich natural gas at high temperatures, generally over a Ni or Co catalyst. Syngas produced by dry reforming has a H2/CO ratio around 1, which makes it CO-rich, and therefore suitable for the production of pure CO or Gas-to-Liquid processes.

Helicobacter pylori‐Induced Persistent IGF2BP1 Activation Promotes Ferroptosis Resistance in Gastric Tumorigenesis

Advanced Science, EarlyView.
Helicobacter pylori infection induces sustained upregulation of the RNA‐binding protein IGF2BP1 in gastric epithelial cells, establishing a persistent epitranscriptomic program. IGF2BP1 stabilizes SLC7A11 mRNA in an m6A‐dependent manner to suppress ferroptosis and promote epithelial survival under oxidative stress. Pharmacological inhibition of IGF2BP1

Dry reforming of methane and interaction between NiO and CeZrPrOx oxide in different crystallographic plane

Next Energy
Methane dry reforming (DRM) holds promise as a pathway for converting methane into valuable synthesis gas (syngas) and high-value chemicals. In this study, we investigate the crystallographic plane interactions between nickel oxide (NiO) and a modified ...

Self‐Healing UPy‐Functionalized Polyethylene Networks: A Robust Platform for Resilient and High‐Performance Lithium Battery Separators

Advanced Science, EarlyView.
Self‐healing separators are developed by grafting ureidopyrimidinone (UPy) quadruple hydrogen‐bonding motifs onto PE‐HEMA copolymers, blended with high‐MW PEO via solvent‐free hot‐pressing. The dynamic UPy network enables autonomous healing, restoring functionality after short circuits.

Bioelectrochemically Powered Out‐of‐Equilibrium Hydrogels Enable Feedback‐Regulated Functions

Advanced Science, EarlyView.
A bioelectrochemically powered hydrogel operates far from equilibrium via an antagonistic redox cycle that regulates disulfide exchange within a polyrotaxane network. Coupling electrochemical mediator cycling with enzymatic feedback enables dynamic control of hydrogel mechanics and transport properties, driving glucose‐responsive insulin release with ...

Thermodynamic analysis of hydrogen production from ethanol- glycerol mixture through steam and dry reforming

, 2015
Thermodynamic properties of ethanol-glycerol steam and dry reforming have been studied with the method of Gibbs free energy minimization for hydrogen production. Equilibrium compositions were determined as a function of H2O/ethanol-glycerol molar ratios (

Sea Cucumber‐Inspired Double‐Network Biopolymer Hydrogels for Programmable Soft Machines

Advanced Science, EarlyView.
Inspired by the mutable dermis of sea cucumbers, the collagen‐alginate double‐network elastomeric (CoDE) hydrogel achieves programmable, recoverable, and functional mechanical behavior. The CoDE hydrogel mimics the mutable stiffness of the sea cucumber dermis through a densified collagen cryogel scaffold that is secondarily reinforced by a dissipative,
