AD–OX: A sequential oxidative process for water treatment— Adsorption and batch CWAO regeneration of activated carbon [PDF]

open access: yes, 2009
A sequential process for water treatment involving usual adsorption on activated carbon (AC) followed by wet air catalytic oxidation of the adsorbed pollutants has been carried out in a fixed bed reactor with a mixture of two model pollutants.

Nature of Current Increase for a CoCrMo Alloy: “transpassive” Dissolution vs. Water Oxidation

open access: yesInternational Journal of Electrochemical Science, 2013
The “transpassive” behavior of a CoCrMo alloy has been investigated to clarify the nature of the current increase at high anodic potential (0.5-0.7 VAg/AgCl).

Recent advances of interfacial modification over tantalum nitride photoanodes for solar water oxidation: a mini review

open access: yesFrontiers in Chemistry
Photoelectrocatalytic (PEC) water splitting represents a highly ideal approach for the efficient conversion of solar energy into sustainable green hydrogen. Although tantalum nitride (Ta3N5) has emerged as a promising photoanode material, its performance

Thinking twice about the evolution of photosynthesis [PDF]

open access: yesOpen Biology, 2019
Sam Granick opened his seminal 1957 paper titled ‘Speculations on the origins and evolution of photosynthesis’ with the assertion that there is a constant urge in human beings to seek beginnings (I concur).
