"The potentially prebiotic chemistry traced by asteroids and comets in the Solar System is therefore replicated, at least in part, in other young planetary systems — suggesting that planets are supplied with these life-bearing elements as they are born".
Eichler, R. et al. The gas phase oxide and oxyhydroxide chemistry of trace amounts of rhenium.
Prof. Saikawa was formerly a research scientist at MIT working with Prof. Prinn on modeling the atmospheric transport and chemistry of trace gases.
In the past 30 years, these models have evolved from rather crude representations of the physics and chemistry impacting trace species to their current state: comprehensive, but not complete.
The 11 groundwater samples were analyzed for major ion chemistry and trace elements, and four samples were analyzed for their δD and δ 18O concentrations, and hydrochemical characteristics.
On Earth, clouds form due to phase change effects, whereas on Venus the clouds exist due to complex chemistry involving trace species.
The versatile and significant potentialities of advanced polarographic and voltammetric methods in environmental trace chemistry of toxic metals are outlined.
Photochemical reactions involving DOC can influence the chemistry of vital trace nutrients such as iron, and, even at dissolved concentrations on the order of one nanomole/kg (1 × 10−9 mole/kg), dissolved organic substances in the upper ocean waters are capable of greatly altering the bioavailability of essential trace nutrients, as, for example, copper and zinc.
Research Interests: Aquatic chemistry and geochemistry, trace element environmental chemistry, nanogeoscience, mercury biogeochemistry, water-particle surface processes.
