Key Challenges for Commercializing Perovskite–Silicon Tandem Solar Cells

open access: yesCarbon Energy, EarlyView.
This review discusses the scientific and technological challenges in advancing perovskite–silicon tandem solar cells (PSTSCs) from lab‐scale to commercial viability, focusing on long‐term stability, scalability, and economic feasibility. Key issues include intrinsic and extrinsic degradation factors, installation conditions, environmental impacts, and ...

A Graph‐Based Generative Artificial Intelligence Methodology for Autocorrection of Utility‐System P&IDs

open access: yesChemie Ingenieur Technik, EarlyView.
This work explores generative AI for automated revision of Piping and Instrumentation Diagrams (P&IDs). We frame P&ID correction as a translation problem, converting attributed P&ID graphs into sequences and learning revisions with a transformer‐based model.

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

open access: yesThe 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 ...

Experimental methods in chemical engineering: The scientific method versus engineering design methodology

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Engineering graduate students confuse the scientific method and problem solving when presenting their pre‐doctoral exams and theses: Science discourse adopts question and hypotheses to assert and establish a study's rationale, while it is problem and objectives in engineering design.

Schülerexperimente zur Synthese naturidentischer, geruchsaktiver Ester im Mikromaßstab durch alkalisch katalysierte Umesterung von Glyceriden

open access: yesCHEMKON, EarlyView.
In diesem Beitrag wird ein einfaches Schülerexperiment vorgestellt, bei dem durch Umesterung von Triacylglyceriden mit n‐Alkanolen im Mikromaßstab geruchsaktive Alkylalkanoate hergestellt werden. Die Reaktion erfolgt alkalisch katalysiert bei Raumtemperatur in kleinen Gefäßen; es entstehen flüchtige Ester mit charakteristischen Frucht‐ und ...
