X-ray induced synthesis of a novel material: Stable, doped solid CO at ambient conditions

Measurement of the Energy and High-Pressure Dependence of X-ray-Induced Decomposition of Crystalline Strontium Oxalate

“…Useful hard X-ray photochemistry has been employed to produce molecular gases, such as Cl 2 , O 2 , and even F 2 in situ inside of diamond anvil cells (DACs) . Recently, these newly developed techniques were employed to decompose strontium oxalate (SrC 2 O 4 ) at ambient conditions . We have observed decomposition of SrC 2 O 4 into strontium carbonate and a novel carbon monoxide (CO)-derived material using synchrotron “white” X-rays from the Advanced Photon Source (APS) via the following proposed chemical reaction where the CO-derived material has some similarities to “polymeric” solid CO (p-CO). , Thus, we proposed a new approach for synthesis of a CO-derived material (possibly p-CO) compared to earlier developed methods. − Previously, it has been shown that when carbon monoxide is pressurized beyond 5.2 GPa, it will transform into p-CO without X-rays.…”

Cationic Dependence of X-ray Induced Damage in Strontium and Barium Nitrate

“…In astrobiology, X-ray-induced chemical reactions in the interstellar environment may lead to the formation of recently observed complex organic molecules . In nuclear physics and weapons design, limiting long-term X-ray damage is critical to ensuring longevity and proper performance of systems. , In biology, X-ray-induced reactions lead to loss of functionality of biologically important molecules, particularly those containing metal centers. − In radiotherapy, X-ray-induced bond breaking reactions are employed to selectively kill cancerous cells. , Additionally, recent work in the developing field of useful hard X-ray photochemistry has shown that X-ray-induced chemical reactions can be harnessed and controlled to synthesize new compounds such as doped solid-CO, a new type of CsO 2, OF 2, and possibly CsF 2 and CsF 3 . Moreover, X-rays can be harnessed to produce simple molecules such as Cl 2 , O 2 , and even F 2 , , in situ inside diamond anvil cells (DACs) for study at high pressure and to serve as reactants for further chemical reactions.…”
