A historical account of how continental drift and plate tectonics provided the framework for our current understanding of palaeogeography [PDF]
, 2018 Palaeogeography is the cartographic representation of the past distribution of geographic features such as deep oceans, shallow seas, lowlands, rivers, lakes and mountain belts on palinspastically restored plate tectonic base maps.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Effect of a finite external heat transfer coefficient on the Darcy-Benard instability in a vertical porous cylinder [PDF]
, 2013 The onset of thermal convection in a vertical porous cylinder is studied by considering the heating from below and the cooling from above as caused by external forced convection processes.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Transient thermal modelling of green anode cooling in the aluminium industry
The Canadian Journal of Chemical Engineering, EarlyView.Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before

Small, EarlyView.Ultrathin freestanding MoSiN nanocomposite membranes are developed as stable and efficient mid‐infrared emitters for gas sensing under extreme thermal conditions. A 12 nm‐thick membrane combines intermetallic phases for enhanced IR absorption with a dielectric phase for mechanical stability.

steel research international, EarlyView.This study uses coupled computational fluid dynamic‐discrete element method (CFD–DEM) simulations to investigate biomass particle injection through a shrouded lance in electric arc furnaces (EAFs). It examines how biomass properties, feed rate, and lance design affect particle dispersion and delivery efficiency.
