Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

Polymer-derived ceramics (PDCs) have been intensively studied for nearly 50 years due to
their unique advantages to producing ceramic fibers, coatings, foams, nanocomposites and …

The electrocatalytic oxygen reduction and evolution of molecular oxygen, known as oxygen
electrocatalysis, is one of the most important reactions that are central to a range of energy …

We study the transformation from molecular to crystalline of (non-) graphitic carbons
synthesized from organic precursors by heat-treatment. Easy assessment of structural …

γ-Graphyne is the most symmetric sp2/sp1 allotrope of carbon, which can be viewed as
graphene uniformly expanded through the insertion of two-carbon acetylenic units between …

We present an overview of the main techniques for production and processing of graphene
and related materials (GRMs), as well as the key characterization procedures. We adopt …

Oxygen vacancy plays an important role in many fields, such as photocatalysis, energy
storages, electro-catalysis, which has been widely investigated both by experiment and …

As fossil fuel resources dwindle and new regulations for a cleaner and safer environment
come on stream, there is growing interest in develo** new sustainable feedstocks for …

High-oxidation-degree graphene oxide particles were synthesized using a modified
Hummers' method. Six different types of particles were synthesized by varying the operating …

The ability to change material properties through phase engineering has long been sought,
with the goal of ad hoc tunability of the physical and chemical properties of the transformed …
