Synthetic chemists have developed robust methods to synthesize discrete molecules, linear
and branched polymers, and disordered cross-linked networks. However, two-dimensional …

Fast detection and identification of microorganisms is a challenging and significant feature
from industry to medicine. Standard approaches are known to be very time-consuming and …

Carbon allotropes built from rings of two-coordinate atoms, known as cyclo [n] carbons, have
fascinated chemists for many years, but until now they could not be isolated or structurally …

Hydrocarbon conversion catalysts suffer from deactivation by deposition or formation of
carbon deposits. Carbon deposit formation is thermodynamically favored above 350° C …

Coals varying in rank from lignite to anthracite were comprehensively characterized with
regard to chemical structure using FTIR and Raman spectroscopy. Structural parameters …

In recent years, the major coal producing areas in China have entered the period of deep
mining, with coal rank changing from low-rank coal (LRC) to middle-high rank coal (MHRC) …

The oxidative aging effect of asphalt binder was investigated using molecular dynamics
simulation in this study. Representative molecular models of aged asphalt were built by …

Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

For decades, discussion of asphaltene structure focused primarily on molecular weight. Now
that it is widely accepted that asphaltene monomers are between∼ 250 and 1200 g/mol …

Understanding how molecules interact to form large-scale hierarchical structures on
surfaces holds promise for building designer nanoscale constructs with defined chemical …
