Electrochemical Ammonia Synthesis and Ammonia Fuel Cells

open access: yesAdvanced Materials, 2018
AbstractAmmonia is a promising platform molecule for the future renewable energy infrastructure owing to its high energy density (when liquefied) and carbon‐free nature. In particular, the interconversion between the chemical and electrical energies leveraging the nitrogen cycle could be an effective approach in mitigating the intermittency of ...

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Enhanced aging properties of HKUST-1 in hydrophobic mixed-matrix membranes for ammonia adsorption. [PDF]

open access: yes, 2016
Metal-organic frameworks (MOFs) in their free powder form have exhibited superior capacities for many gases when compared to other materials, due to their tailorable functionality and high surface areas.

Effects of available surface on gaseous emissions from group-housed gestating sows kept on deep litter

open access: yesAnimal, 2010
In the European Union, the group-housed pregnant sows have to have a minimal legal available area of 2.25 m2/sow. However, it has been observed that an increased space allowance reduces agonistic behaviour and consecutive wounds and thus induces better ...

Au@h‐BN Core–Shell Nanostructure as Advanced Shell‐Isolated Nanoparticles for In Situ Electrochemical Raman Spectroscopy in Alkaline Environments

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates the stability and Raman signal enhancement effects of Au@h‐BN nanoparticles in an alkaline electrolyte on. A comparison between conventional SiO2 and h‐BN shells reveals that the h‐BN core‐shell structure provides superior stability and enhanced Raman intensity over multiple cyclic voltammetry cycles.

Evaluation of a spacecraft nitrogen generator [PDF]

open access: yes
An experiment was completed to demonstrate that low ammonia concentrations in the product nitrogen stream are possible using the staging concept. Mixtures of nitrogen, hydrogen and ammonia were fed into a temperature controlled packed bed ammonia ...

Nitrogen efficiency of dairy cattle : from protein evaluation to ammonia emission [PDF]

open access: yes, 2011
Diet optimization contributes considerably to increased nitrogen efficiency of dairy cattle, resulting in reduced nitrogen losses. This thesis focuses on three themes: the potential advances in protein evaluation systems for ruminants, the relationship ...

First Detection of Ammonia in the Large Magellanic Cloud: The Kinetic Temperature of Dense Molecular Cores in N159W [PDF]

open access: yes, 2009
The first detection of ammonia (NH3) is reported from the Magellanic Clouds. Using the Australia Telescope Compact Array, we present a targeted search for the (J,K) = (1,1) and (2,2) inversion lines towards seven prominent star-forming regions in the ...

Brain edema in acute liver failure. A window to the pathogenesis of hepatic encephalopathy

open access: yesAnnals of Hepatology, 2003
Hepatic encephalopathy and brain edema are important complications in the course of a patient with acute liver failure. Presumed unrelated for many years, increasing evidence suggests that an increase in brain water is seen in all forms of hepatic ...
