Sustainable Aviation Fuel—An Innovative Approach for Developing an Optimized Methanol‐Based Production Pathway

open access: yesChemie Ingenieur Technik, EarlyView.
Growing air traffic increases the contribution of aviation fuels to global emissions. With few viable alternatives for decarbonizing aviation, Sustainable Aviation Fuels (SAF) are a key lever. Green methanol enables a flexible synthetic production pathway, but realizing a specification‐compliant 100% drop‐in fuel requires overcoming significant ...

Challenges in the Market Ramp‐Up of Electrolysis and PtX From a Technical Perspective

open access: yesChemie Ingenieur Technik, EarlyView.
This publication examines Power‐to‐Fuels pathways for decarbonizing transport and industry. Two ramp‐up scenarios assess electrolysis and fuel synthesis capacity needs for road transport and aviation in Germany through 2050. It addresses investments, technologies, cost reduction, industrial scale‐up, material efficiency, performance, and e‐fuels ...

DAC-JAX: A JAX Implementation of the Descript Audio Codec [PDF]

open access: yes
We present an open-source implementation of the Descript Audio Codec (DAC) using Google's JAX ecosystem of Flax, Optax, Orbax, AUX, and CLU. Our codebase enables the reuse of model weights from the original PyTorch DAC, and we confirm that the two ...

Experimental methods in chemical engineering: Temperature‐programmed desorption—TPD

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed desorption (TPD) characterizes the surface active sites of functional materials, such as adsorbents (metal hydrides, porous carbons, zeolites, metal–organic frameworks, for example) and catalysts. Solids surfaces are pre‐treated to remove moisture, contaminants, and previously adsorbed species, then a probe molecule (NH3$
