Interaction of inflammation and hyperoxia in a rat model of neonatal white matter damage

Yohan Van de Looij

Intrauterine infection and inflammation are major reasons for preterm birth. The switch from placenta-mediated to lung-mediated oxygen supply during birth is associated with a sudden rise of tissue oxygen tension that amounts to relative hyperoxia in prete ...

Selective three-phase hydrogenation of aromatic nitro-compounds over beta-molybdenum nitride

Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey

A tetragonal molybdenum nitride (beta-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N-2 + H-2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; P-H2 = 11 bar) of a series of para- ...

β-Molybdenum nitride: synthesis mechanism and catalytic response in the gas phase hydrogenation of p-chloronitrobenzene

Lioubov Kiwi, Fernando Cardenas Lizana

A temperature programmed treatment of MoO3 in flowing N-2 + H-2 has been employed to prepare beta-phase molybdenum nitride (beta-Mo2N) which has been used to promote, for the first time, the catalytic hydrogenation of p-chloronitrobenzene. The reduction/ni ...

Toxic metal interactions with soil bacterium "Cupriavidus metallidurans"

Rita Hajdu Schenk

Living bacteria offer an ecological and cost-effective alternative to the classical physical and chemical techniques for the treatment of environmental contaminations. Although their increasing use in toxic metal removal, systematic studies on the influenc ...

Exploratory Synthesis and Characterization of High Nuclearity Cluster-Based Compounds

Wendy Lee Queen

In light of the already proven applications of transition-metal (TM) oxide clusters, including catalysis, selective sorption, sepns., mol. recognition, environmental decontamination, and nanotechnol., one can imagine that the development of framework mater ...

American Chemical Society2009

Control over the structure of metals at the mesoscale (2-50 nm) is crucial for emerging applications such as energy conversion, sensing, and information processing. The self-assembly of nanoparticles with block copolymers provides a natural entry point to ...

Diffuse release of environmental hazards by railways

Luca Rossi

There is increasing concern about environmental pollution by diffuse emissions of various environmental hazards emitted by transportation activities. For the first time substances released by railways to the environment were investigated. We considered the ...

Linking chemical speciation to metal bioavailability

Cristina Lamelas

It is recognized that dissolved organic matter (DOM) plays an utmost role in aquatic ecosystems by binding trace metals and influencing their speciation, bioavailability and detrimental effects. DOM is considered to protect the aquatic microorganisms from ...

Non-GMO approach for the improvement of heavy metal accumulation and extraction of high yielding crop species for efficient phytoextraction of contaminated soil

Erika Nehnevajova

Some plants able to take up heavy metals from contaminated soils offer a possibility to clean up sites contaminated with heavy metals. Plants thus act as a solar driven pump, which can extract and concentrate heavy metals from the environment. Since most o ...
