Nuclear Engineering and TechnologyThe failure fraction of tri-structural isotropic (TRISO)-coated particles in the fuel elements of the core is a key indicator for characterizing the radiation safety of a high-temperature gas-cooled reactor (HTGR) and can be determined from accurate ...

AIChE Journal, EarlyView.Abstract Mixed‐conducting ceramic hollow fiber membranes are a versatile platform for oxygen separation, value‐added chemical production, and oxy‐combustion. Because oxygen permeation is thermally activated, these systems typically rely on bulky, energy‐intensive furnaces that suffer from low efficiency and large thermal inertia.

High-temperature gas-cooled reactor (HTGR): long term program plan
, 1980 The FY 1980 effort was to investigate four technology options identified by program participants as potentially viable candidates for near-term demonstration: the Gas Turbine system (HTGR-GT), reflecting its perceived compatibility with the dry-cooling ...

How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39
AIChE Journal, EarlyView.Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.

Model predictive control with inline parameter adaptation for direct crystal growth rate regulation
AIChE Journal, EarlyView.Abstract In batch cooling crystallization, many interactive factors, including supersaturation, reactor dimensions, and operating conditions, govern crystal growth and significantly influence product properties. Variables such as temperature or refractive index are used as surrogate control variables but have limitations in capturing growth rate ...

Angewandte Chemie International Edition, EarlyView.We introduce the Aza‐Büchner–Curtius–Schlotterbeck (ABCS) reaction: A mild, catalyst‐free method for homologating aryl imines. Diverging from the traditional BCS mechanism, the diazo intermediate undergoes selective C─C insertion to form an all‐carbon quaternary center.
