Ion-exchange reactions of Na2Cu2TeO6 with excess of lithium nitrate at low temperature (300 °C) readily resulted in an isostructural honeycomb ordered monoclinic layered structure Li2Cu2TeO6, otherwise inaccessible by direct solid state high temperature reactions. Similarly, Li2Ni2TeO6(I) stabilized approximately in equal amounts in both of the known P2-type polymorphs (P6(3)/mcm and P6(3)22) w...

Mitochondria isolated from potato tubers fail to undergo passive osmotic swelling when suspended in isotonic Na(+) acetate or phosphate, in NaCl following addition of tripropyltin, or in Na(+) nitrate following addition of an uncoupler. Swelling under each of these conditions in mitochondria from other sources has been attributed to the inward movement of Na(+) on an endogenous Na(+)/H(+) excha...

[1] Surface nutrients and dissolved inorganic carbon (DIC) in the central (CEP) and eastern equatorial Pacific (EEP) show much higher concentrations to the south than to the north of the equator. In this study, the physical and biological controls on this asymmetry are investigated using a coupled physical-biogeochemical model. Two numerical experiments are conducted to examine the effects of a...

BACKGROUND AND AIMS Respiration of autotrophs is an important component of their carbon balance as well as the global carbon dioxide budget. How autotrophic respiration may respond to increasing carbon dioxide concentrations, [CO(2)], in the atmosphere remains uncertain. The existence of short-term responses of respiration rates of plant leaves to [CO(2)] is controversial. Short-term responses ...

Olefin metathesis catalysts like AquaMet are vulnerable to different decomposition pathways under biologically relevant conditions. Currently, stabilizing strategies focused on approaches with limited relevance for application Initial attempts stabilise by encapsulation within a supramolecular metallocage showed that the nitrate counterions of cage improve activity catalyst. We show chloride li...

Urbanization negatively impacts water quality in streams by reducing stream-groundwater interactions, which can reduce a stream's capacity to naturally attenuate nitrate. Meadowbrook Creek, first order urban stream Syracuse, New York, has an inverse urbanization gradient, with heavily urbanized headwaters that are disconnected from the floodplain and downstream reaches have intact riparian floo...

With the first ever synthesis of monoazidopentaerythritol trinitrate, a comparative study properties all azidonitrate derivatives from pentaerythritol tetranitrate (PETN) to tetraazidopentaerythritol (TAPE) was possible. The azides were prepared by halogen azide exchange and remaining alcohols then converted into organic nitrate esters using acetyl nitrate. resulting compounds (PETN), mononitra...
