On the Influence of Catalyst Mesopore Structure in the Catalytic Cracking of Polypropylene

ChemistryEurope, Volume 4, Issue 2, February 2026.
Catalytic cracking is a promising approach to convert polyolefin plastics into hydrocarbons. Herein, the effect of catalyst pore size in polypropylene cracking using amorphous silica–alumina with identical external acidity, but varying mesopore diameters and particle sizes, is isolated. Mesopore size has minimal effect on activity, indicating that high

Depolymerisation of γ‐Valerolactone Organosolv Lignins with Unsupported Molybdenum‐Based Catalysts

ChemSusChem, Volume 19, Issue 3, February 2026.
Lignins from γ‐valerolactone organosolv fractionation were depolymerised in ethanol using unsupported molybdenum catalysts. Over 90% yields of low‐molecular‐weight lignin oil were obtained with minimal char formation, yields of the aromatic monomers being 7–16 wt%.

Highly Sensitive Dopamine Electrochemical Sensor Using Pt Nanoparticles on CNTs/Polypyrrole Nanocomposites

Electrochemical Science Advances, Volume 6, Issue 1, February 2026.
ABSTRACT Dopamine (DA) plays a vital role as a neurotransmitter in the central nervous system (CNS), and its accurate quantification is essential for diagnosing neurological disorders. However, selective and sensitive detection of DA in complex biological matrices remains a challenge due to interference from coexisting biomolecules.

Systems‐Level Optimization of Hybrid Produced Water Treatment Systems for Sustainable Oil and Gas Production: A Review of Current Technologies

Global Challenges, Volume 10, Issue 2, February 2026.
ABSTRACT Produced water (PW) is the largest and most complex waste stream generated during oil and gas production, posing significant environmental, operational, and regulatory challenges due to its high salinity, dispersed hydrocarbons, toxic organics, heavy metals, and naturally occurring radioactive materials. Although numerous studies have reviewed

Comprehensive Surrogate Models for Predicting the Melt Conveying Characteristics of Channel Segments in High‐Performance Single‐Screw Extruders

Polymer Engineering &Science, Volume 66, Issue 2, Page 716-738, February 2026.
Generalized analytical equations were developed that accurately predict the local pumping characteristics, viscous dissipation, and average shear rates in channels of both conventional and high‐performance single‐screw extruders. Applied within segmented extruder calculations, these models aid in screw design and process troubleshooting without the ...
