Distribution and Thermal Maturity of Devonian Carbonate Reservoir Solid Bitumen in Desheng Area of Guizhong Depression, South China

open access: yesGeofluids, 2017
The distribution of solid bitumen in the Devonian carbonate reservoir from well Desheng 1, Guizhong Depression, was investigated by optical microscope and hydrocarbon inclusions analysis. Vb and chemical structure indexes measured by bitumen reflectance,

Thermal behaviour of bitumen modified by sulphur addition [PDF]

open access: yes, 2012
The most frequent use of bitumen is as binder for pavement applications. The effect of sulphur addition on the properties of the bitumen has been extensively studied several decades ago.

Multivariate Optimization of Column Liquid Chromatography for the Separation of Saturated, Aromatic, and Acidic Biomarkers in Petroleum and Rock Extracts

open access: yesJournal of Chemometrics, Volume 40, Issue 2, February 2026.
ABSTRACT Conventional geochemical biomarkers include saturated, aromatic, and carboxylic acid compounds. Saturated and aromatic biomarkers, however, form the foundation of many geochemical studies because of their abundance and intrinsic significance.

Experimental methods in chemical engineering: Electrospinning

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 2, Page 556-568, February 2026.
Abstract Electrospinning produces micro‐ and nanofibres by forcing a polymeric solution through a fine needle in an electric field that produces a filament that accumulates onto a collector plate. The fibre morphology depends on solution properties, distance between needle and plate, feed rate, and electric field intensity.

Hydrothermal dolomitisation of a deep‐water bioherm isolated in a non‐dolomitised intraplatform basin within the Norian Dolomia Principale (Southern Alps, northern Italy)

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
We propose that one of the largest known bioconstructions (the Monte Zenone bioherm) in the Southern Alps, northern Italy, and its growth on a tilted and drowned platform block of the Norian Dolomia Principale was controlled by hydrothermal dolomitisation from fault‐controlled fluids during the Late Triassic–Early Jurassic rifting phase. Dolomitisation
