THE chromatographic separation of argon and oxygen is difficult, and existing methods depend on one of the following techniques: (1) Separation on a molecular sieve 5 Å column at 18° C (ref.

Researchers told Space.com how they looked for novel ways for molecular oxygen to form by smashing CO2 with helium. Experts tend to gauge how likely life may exist on a planet by how much oxygen ...

"This study shows another pathway to produce molecular ... to say O2 is formed this way. To prove their theory, the scientists employed time-of-flight (TOF) mass spectrometry, a technique that ...

KCL Department of Biophysics: glass and acetate slides ('quarter plates', 'whole plates' and 'half plates') relating to the work of the Medical Research Council (MRC) Biophysics Research Unit (KCL ...

Origins are therefore said to be 'licensed' for replication during G1 phase, whereas the license is removed during replication. At the molecular level, licensing of origins involves the sequential ...

Following the success of Virgin Media’s initial rollout of smart support to existing customers earlier this year – which has benefited over 50,000 users so far – the second phase focuses on ... Virgin ...

Despite their potential, however, the magnetic phase diagram of these materials remains largely unexplored. To uncover more, a team of researchers, led by Professor Ryuji Tamura from the ...

In plants, there is a complex and multilevel network of the antioxidative system (AOS) operating to counteract harmful reactive species (RS), the foremost important of which are reactive oxygen ...
