The search for new materials is intimately linked to the development of synthesis methods. In
the current urge for the sustainable synthesis of materials, taking inspiration from Nature's …

High-pressure synthesis (which refers to pressure synthesis in the range of 1 to several
GPa) adds a promising additional dimension for exploration of compounds that are …

We report the synthesis of bulk, highly oriented, crystalline 4 H hexagonal silicon (4 H-Si),
through a metastable phase transformation upon heating the single-crystalline Si 24 …

A two-step process for the synthesis of the silicon clathrate film on a diamond silicon wafer is
explored in detail. Key factors impacting the film quality are uncovered. We find that the …

Si 24 is a new, open-framework silicon allotrope that is metastable at ambient conditions.
Unlike diamond cubic silicon, which is an indirect-gap semiconductor, Si 24 has a …

The pVT equation of state of magnesium metal has been measured up to 20 GPa and 1500
K using both multianvil and opposite anvil techniques combined with synchrotron x-ray …

It is well established that metal atoms can be used to regulate porosity in synthesis and
porous structures can be obtained by removing metal atoms. Motivated by a recent synthesis …

The inorganic chemistry of the Na–Si system at high pressure is fascinating, with a large
number of interesting compounds accessible in the industrial pressure scale, below 10 GPa …

Isothermal equations of state were determined for the open-framework silicon allotrope Si 24
and its sodium-filled precursor (Na 4 Si 24) using different pressure media including …

In this work we present a detailed structural characterization of Si-4H, a newly discovered
bulk form of hexagonal silicon (Si) with potential optoelectronic applications. Using multi …
