Photocatalytic degradation of phenol red using complexes of some transition metals and hydrogen peroxide [PDF]

Journal of the Serbian Chemical Society, 2008
The photocatalytic degradation of Phenol Red was investigated using thiocyanate complexes of iron, copper, cobalt and hydrogen peroxide. The rate of photocatalytic degradation of the dye was followed spectrophotometrically. The effect of the variation of

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions

Advanced Functional Materials, EarlyView.
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

Chemical Processes in Protoplanetary Disks II. On the importance of photochemistry and X-ray ionization [PDF]

, 2012
We investigate the impact of photochemistry and X-ray ionization on the molecular composition of, and ionization fraction in, a protoplanetary disk surrounding a typical T Tauri star. We use a sophisticated physical model, which includes a robust treatment of the radiative transfer of UV and X-ray radiation, and calculate the time-dependent chemical ...

Influence of the sodium/proton replacement on the structural, morphological and photocatalytic properties of titanate nanotubes [PDF]

Journal of Photochemistry and Photobiology A: Chemistry, 232 (2012) 50-56, 2012
Titanate nanotubes (TNT) with different sodium contents have been synthesised using a hydrothermal approach and a swift and highly controllable post-washing processes. The influence of the sodium/proton replacement on the structural and morphological characteristics of the prepared materials was analysed.

Hydrocarbon ratios during PEM-WEST A: A model perspective [PDF]

, 1996
A useful application of the hydrocarbon measurements collected during the Pacific Exploratory Mission (PEM-West A) is as markers or indices of atmospheric processing. Traditionally, ratios of particular hydrocarbons have been interpreted as photochemical

An assessment of western North Pacific ozone photochemistry based on springtime observations from NASA's PEM-West B (1994) and TRACE-P (2001) field studies [PDF]

, 2003
The current study provides a comparison of the photochemical environments for two NASA field studies focused on the western North Pacific (PEM-West-B (PWB) and TRACE-P (TP)).

“Writing” Crystal Phases in Amorphous Calcium Carbonate via Laser‐Induced Patterned Transformations

Advanced Functional Materials, EarlyView.
Laser‐induced crystallization enabling the patterning of amorphous calcium carbonate into various distinct phases is introduced. This approach provides spatial control over polymorph selection, both crystalline and amorphous, inspired by biomineralization pathways.

Tailoring of organic dyes with oxidoreductive compounds to obtain photocyclic radical generator systems exhibiting photocatalytic behavior

Beilstein Journal of Organic Chemistry, 2014
The combination of a dye which absorbs the photon, an electron acceptor and an electron donor leading to energy conversion through electron transfer, was the basis of the so called three-component systems.
