In petroleum science, asphaltenes are well-known as the most refractory fraction of crude oil
and remain infamous for problems in production, transportation, and refining processes …

Previously, asphaltene science had been hindered by many significant uncertainties
regarding molecular weight, molecular structure, and nanocolloidal characteristics in …

It was a long-cherished dream for chemists to take a direct look at chemical bonding, a
fundamental component of chemistry. This dream was finally accomplished by the state-of …

Petroleum pitch has played a significant role in carbon science as a key abundant resource
for polycyclic aromatic hydrocarbons in making various higher value carbon materials …

Despite extensive research, the molecular-level chemical characterization of asphaltenes, a
highly aromatic solubility fraction of petroleum, remains an analytical challenge. This fraction …

Fluid distributions throughout oilfield reservoirs have been measured with increasing
accuracy and coverage, both vertical and laterally, in recent years. Currently, a routine …

The structural parameters and average molecular structures of the asphaltenes obtained
from the Aguacate oilfield, located in the Golden Lane of Mexico, have been investigated …

Glaser‐like coupling of terminal alkynes by thermal activation is extensively used in on‐
surface chemistry. Here we demonstrate an intramolecular version of this reaction performed …

Asphaltene precipitation can cause clogged pipelines, of which the alleviation costs the oil
industry billions of dollars per year. Asphaltenes are a diverse set of macromolecules native …

Five asphaltene samples from three different source types–immature source rock (ISA),
petroleum (PA), and coal (CDA)–are studied using integrated chemical and spectroscopic …
