Enhancing Efficiency in Double‐Pipe Heat Exchangers: A Detailed Review of NanoFluids and Their Impact on Thermal Performance

Heat Transfer, Volume 55, Issue 1, Page 212-240, January 2026.
ABSTRACT This study reviews recent advances in using nanofluids to enhance double‐pipe heat exchanger (DPHE) efficiency. The review examines several types of nanofluids, that is, water‐based graphene oxide and CuO–water nanofluids, assessing their effectiveness under different operating conditions, including inlet temperature and nanoparticle volume ...

Exploring the Effects of Reduced Gravitational Field Impacts on Convective Heat Transfer: A Comprehensive Review

Heat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.
ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

Process and model of a chemically buffered supported liquid membrane system for cobalt extraction

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 1, Page 154-164, January 2026.
Abstract BACKGROUND Cobalt is a valuable metal whose total annual supply from recycling is projected to be 34 000 t by 2030, primarily from batteries. Supported liquid membrane (SLM) technology is emerging as a promising technology alternative to conventional hydrometallurgy for cobalt recovery.

Unified Permeability Modeling for Transitional Darcy/Non‐Darcy Flow Based on 3D Pore‐Level Numerical Flow Tests

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 1, Page 162-177, January 2026.
ABSTRACT This study presents a unified representation of the seepage characteristics of virtual soil, such as the transition zone from low‐velocity Darcy flow to high‐velocity non‐Darcy flow, by conducting 3D pore‐level fluid simulations. The process of defining a virtual test region as a representative volume element (RVE) and then assessing the ...

A Probabilistic Cut Finite Element Method With Random Field Generator and Bayesian Model Calibration for Flow Through Rough Cracks

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 1, Page 298-320, January 2026.
ABSTRACT A new model for the simulation of fluid flow through rough cracks is presented. The model combines a probabilistic cut finite element method (PCutFEM) to capture the unfitted boundary condition at the fluid interface, with a stochastic random field generator to represent the crack asperities.

One‐Step Assembly of α‐Aryl‐Substituted DOTAs as Superior and Universal Platforms for Multifunctional Theranostics

Angewandte Chemie, Volume 137, Issue 50, December 8, 2025.
A one‐step multi‐component synthetic approach is reported to construct α‐aryl‐substituted DOTAs, which required tedious multi‐step synthesis in all previous works. The synthesized α‐aryl‐substituted DOTAs showed improved performance for developing multifunctional theranostics and represent a universal platform for bioconjugation. Abstract α‐Substituted

Support Structure Modelling in Actuator Line Method Large Eddy Simulations of Wind Turbine Wakes

Wind Energy, Volume 29, Issue 1, January 2026.
ABSTRACT While advancements in the prediction of wind turbine loads and wakes within the actuator line method large eddy simulation (ALM‐LES) framework have been an active research topic in recent years, the modelling of the tower and nacelle has received comparatively less attention.
