AIChE Journal, Volume 72, Issue 8, August 2026.Abstract Electrification of distillation offers a promising route to reducing scope‐1 emissions from one of the chemical industry's most energy‐intensive unit operations. However, conventional adiabatic columns are dynamically inflexible: Long, energy‐intensive start‐ups make shutdown and restart impractical under variable electricity prices and ...

Fuel Cells, Volume 26, Issue 4, August 2026.ABSTRACT Direct glycerol fuel cells (DGFCs) are a promising technology, but scaling them remains a challenge due to persistent technological and economic limitations. In this context, process simulation and modeling emerge as crucial tools. This study addresses the implementation of a conventional alkaline DGFC stack model in Aspen Plus and proposes a ...

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 11, 16 July 2026.Deprotonotion of a β‐diketiminate ligand with a tethered secondary amine resulted in highly stable heteroleptic complexes, but the formation of the dianionic ligand could not be achieved. The alkaline‐earth (Ae) metal chemistry of a β‐diketiminate (BDI) ligand with a bulky Ar‐substituent and a pendant amine arm was investigated. The ligand precursor HC[

Methods of separation of azeotrope mixtures by distillation
, 2018 Ovaj se rad bavi metodama destilacijskog razdvajanja azeotropnih smjesa. Kod azeotropnih smjesa, jednostavnom kolonskom destilacijom ne mogu se dobiti obje čiste komponente bez određenih modifikacija destilacijskog postupka, npr.
