Bond and Antibond Resonances: A Unified Framework for Singlet Biradical Character

Chemistry – A European Journal, EarlyView.
The electronic structure of a variety of singlet biradicaloids may be described in the Lewis picture using single antibonds as the central bonding motif. In conjunction with a consistent set of biradical indicators, we can resolve some long‐standing disputes over the biradical character of molecules such as O3 and S2N2.

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.

Self‐Similar Blowup for the Cubic Schrödinger Equation

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.
