Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Neue Versuche mit Spiropyran: Photometrie, NMR‐Spektroskopie und On‐Water‐Synthese

CHEMKON, EarlyView.
Reaktionskinetik wird häufig als schwierig, theoretisch und Mathematik‐lastig empfunden, weshalb experimentelle Zugänge für diesem Themenbereich notwendig sind. In diesem Beitrag werden entsprechende Versuche zur Reaktionskinetik vorgestellt, bei denen das Farbstoffsystem eines Spiropyrans und dessen isomerer Merocyanin‐Form untersucht wird.

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

Energy Landscapes in Chemical Reactions and Transport

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.
