Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals

open access: yesAngewandte Chemie, EarlyView.
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...

Hydrogen Production from Ammonia Electrochemical Cracking

open access: yesAdvanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Numerical Approximation of the In Situ Combustion Model Using the Nonlinear Mixed Complementarity Method

open access: yesFluids
In this work, we study a numerical method to approximate the exact solution of a simple in situ combustion model. To achieve this, we use the mixed nonlinear complementarity method (MNCP), a variation of the Newton method for solving nonlinear systems ...

Habitat‐Specific Design Strategies for Untethered Soft Robots

open access: yesAdvanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

CINÉTICA DE PROCESOS DE COMBUSTIÓN IN SITU: UNA DISCUSIÓN DE LOS MODELOS CINÉTICOS

open access: yesRevista Fuentes El Reventón Energético, 2013
In situ combustion is a thermal enhanced heavy oil recovery method in which a portion of the oil is burned (approximately 10%) due to the reaction with oxygen or any other oxidant gas with the purpose of generating energy as heat.

Laboratory Study on Corrosion Mechanism of Production System in In Situ Combustion

open access: yesGeofluids, 2020
The corrosion problem of a production system has been affecting the normal operation of an in situ combustion project. Because the environment of production system is significantly different in tubing, gas, liquid, and temperature in in situ combustion ...

CeO2‐Based Electrocatalysts for the Oxygen Evolution Reaction: Design, Dynamic Mechanisms, and Electrolyte Adaptability

open access: yesAdvanced Science, EarlyView.
This Review shows how cerium oxide helps water‐splitting catalysts work better and last longer. It explains how CeO2 tunes electronic structure, oxygen‐vacancy behavior, and surface reconstruction, while adapting to alkaline, acidic, and seawater conditions.

ANÁLISIS DE LOS GASES DE COMBUSTIÓN - EL VERDADERO ROL DE LAS PRUEBAS DE TUBO

open access: yesRevista Fuentes El Reventón Energético, 2012
During and after a combustion tube test, when the post-core is disassembly and removed, the produced fluids are amalysed. The emulsions are analyzed by the addition of toluene and centrifugation.
