Numerical Study of MHD Hybrid Nanofluid Flow With Multiple Slip Effects Over a Variable Porous Stretching Surface

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work discusses the thermal performance of magnetized hybrid nanofluid flow over a variable porous stretchable surface, emphasizing the underlying physical mechanisms governing heat and mass transfer. The Cattaneo–Christov flux model is used in place of Fourier's and Fick's laws to incorporate relaxation effects, ensuring a more realistic ...

Composition‐Tunable Lignocellulosic Aerogels From Eucalyptus spp. Bark for Oil and Cu2+ Adsorption

Journal of Applied Polymer Science, EarlyView.
Composition‐tunable lignocellulosic aerogels are produced from Eucalyptus spp. bark by combining cellulose, lignin, and microfibrillated cellulose without post‐synthetic functionalization. The resulting porous architectures show contaminant‐dependent performance: CEL favors cooking‐oil uptake, CEL‐M favors pump‐oil uptake, and CEL‐L‐M provides the ...
