Phosphorus: an elemental catalyst for diamond synthesis and growth
Summary
Elemental phosphorus was used to synthesize diamond crystals from graphite. This research explores phosphorus as a novel catalyst for creating n-type semiconducting diamond materials.
Area of Science:
- Materials Science
- Solid-State Chemistry
- Crystallography
Background:
- For over 30 years, 12 transition metals have been the only known elemental catalysts for diamond synthesis.
- No new elemental catalysts have been reported since the initial discovery.
- Group V elements are of significant interest for producing n-type semiconducting diamond.
Purpose of the Study:
- To investigate the catalytic potential of elemental phosphorus for diamond synthesis.
- To explore the feasibility of producing n-type semiconducting diamond using phosphorus.
- To synthesize single-crystal diamond on a seed crystal.
Main Methods:
- Diamond synthesis from graphite using elemental phosphorus.
- Application of high pressure (7.7 gigapascals) and high temperature (1800 degrees C).
- Growth of single-crystal diamond on a pre-existing diamond seed crystal.
Main Results:
- Successful synthesis of diamond from graphite in the presence of elemental phosphorus.
- Demonstration of phosphorus as a viable elemental catalyst for diamond production.
- Growth of single-crystal diamond was achieved.
Conclusions:
- Elemental phosphorus can serve as a catalyst for diamond synthesis.
- This study expands the range of known elemental catalysts for diamond production.
- Phosphorus-catalyzed synthesis offers a pathway to n-type semiconducting diamond.

Cofactors and Coenzymes
Enzymes require additional components for proper function. There are two such classes of molecules: cofactors and coenzymes. Cofactors are metallic ions and coenzymes are non-protein organic molecules. Both of these types of helper molecule can be tightly bound to the enzyme or bound only when the substrate binds.

Cofactors and Coenzymes
Enzymes are proteins made of amino acids. The functional group of each constituent amino acid catalyzes a wide variety of chemical reactions via ionic interactions or acid-base reactions. However, amino acids cannot catalyze oxidation-reduction and group transfer reactions and need to be aided by non-protein components called cofactors. Cofactors are also referred to as the chemical teeth of an enzyme.

Heterogeneous Catalysis
Heterogeneous catalysis involves a catalyst in a different phase from the reactants. It is a process where the catalyst and the reactants are in distinct phases, typically solid and gas or liquid.Most heterogeneous catalysts are metals, metal oxides, or acids. The list includes transition metals like iron (Fe), cobalt (Co), nickel (Ni), palladium (Pd), platinum (Pt), chromium (Cr), manganese (Mn), tungsten (W), silver (Ag), and copper (Cu). These metals possess partially vacant d orbitals that...
Accelerators
Accelerators in concrete serve as admixtures to speed up the hardening process, enabling the concrete to achieve early strength faster. Although accelerators do not necessarily impact the time it takes concrete to set, they reduce this time in practice. A common accelerator is calcium chloride, which is particularly useful for hastening early strength development in cold weather or for rapid repair jobs that require quick heat generation after mixing.

Additives and Fillers in Concrete
Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.
