Beyond Furnaces: Harnessing In Situ Joule Heating for Efficient C1 Catalysis

Carbon Energy, EarlyView.
Joule‐heated catalysis directly converts electrical energy into localized heat within conductive catalysts, overcoming the heat‐transfer limitations of conventional furnaces. This review summarizes recent advances in C1 molecule conversion, including CO2 methanation, reforming for hydrogen production, and HCHO/CO oxidation, while highlighting ...

Numerical simulation of an explosion in a simple scale model of a nuclear reactor

Computer Assisted Methods in Engineering and Science, 2023
In the case of a Hypothetical Core Disruptive Accident (HCDA) in a Liquid Metal Fast Breeder Reactor, it is assumed that the core of the nuclear reactor has melted partially and that the chemical interaction between molten fuel and liquid sodium creates

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
Sunlight‐driven synthesis offers a green and energy‐efficient route to metallic nanoparticles. Here, double‐vacancy halide perovskites (Cs2PtX6, X = Cl, Br) act as photoactive precursors for the in‐situ formation of ultrasmall (< 3 nm) platinum nanoparticles under simulated sunlight at room temperature.

Research on the positioning strategy for CRDM penetrations in reactor vessel head

Nuclear Engineering and Technology
The reactor vessel head is a core component of the nuclear reactor. Internally, multiple penetrations are connected through interference fit and welding, which are prone to generate Primary Water Stress Corrosion Cracking (PWSCC).

In situ Generation of Fluoride Catalysts for CO2‐to‐Formic Acid Conversion With Silicon Reducing Agent

Chemistry – A European Journal, EarlyView.
Reductive conversion of CO2 to formic acid with waste silicon reducing agent catalyzed by in situ generation of active fluoride species from a tertiary amine, protonic acid, and simple inorganic fluoride salt, such as KF and NaF. ABSTRACT The activation and catalytic reduction of carbon dioxide (CO2) using silicon‐based reducing agents is an important ...

A New Spin on Photocatalysis: Vortex Fluidic‐Driven Photooxidations Enabled by Solution‐Processable Microporous Polymers

Chemistry – A European Journal, EarlyView.
Newly developed polymers with intrinsic microporosity (PIMs) were combined with benzo[c][1,2,5]thiadiazole (BTZ) to be used as visible light photocatalytic coatings on the Vortex Fluidic Device (VFD). The VFD's rapid rotation and continuous flow capabilities enhanced singlet oxygen and superoxide radical reactions, achieving a dramatic eightfold ...

Control of Gemcitabine Activity With Blue and Red Light

Chemistry – A European Journal, EarlyView.
Treating cancer with chemotherapy is generally associated with many side effects, which can be addressed by selectively releasing the desired drugs with visible light. Sixteen new blue light‐activatable cytostatics were introduced, with the gemcitabine derivative exhibiting ideal properties.

Assessment of thermal safety margins for the IVR-ERVC strategy of the i-SMR using the CINEMA code

Nuclear Engineering and Technology
In-vessel corium retention with external reactor vessel cooling (IVR-ERVC) is a key severe accident mitigation strategy to prevent lower-head failure and retain fission products inside the reactor vessel. This study assesses the applicability of IVR-ERVC

First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases

Chemie Ingenieur Technik, EarlyView.
A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...
