Ammonia/Hydrogen and Cracked Ammonia Combustion

open access: yesEnergy & Fuels
Ammonia is a promising energy carrier for energy system decarbonization, although several drawbacks affect its combustion process. Coupling moderate or intense low-oxygen dilution (MILD) combustion with the use of high reactivity fuels allows to improve NH3 combustion.

Determination of Blood Ammonia Using the Ammonia Checker [PDF]

open access: yesAnnals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1983
A new diffusion method employing bromocresol green for determination of blood ammonia (Ammonia Checker R ) using disposable reagent test-plates and a pocket-size colorimeter with direct readout of results was compared with an enzymatic method. The values obtained with the Ammonia Checker were

The ammonolysis of esters in liquid ammonia

open access: yes, 2013
The rates of ammonolysis of alkyl benzoate and phenylacetate esters in liquid ammonia increase with the acidity of the leaving group alcohol and show relatively large Brønsted βlg values of −1.18 and −1.34, respectively, when plotted against the aqueous ...

Research on the technical scheme of multi-stack common rail fuel cell engine based on the demand of commercial vehicle

open access: yesEnergy and AI
At present, most fuel cell engines are single-stack systems, and high-power single-stack systems have bottlenecks in meeting the power requirements of heavy-duty trucks, mainly because the increase in the single active area and the excessive number of ...

Ammonia toxicity to the brain [PDF]

open access: yesJournal of Inherited Metabolic Disease, 2012
AbstractHyperammonemia can be caused by various acquired or inherited disorders such as urea cycle defects. The brain is much more susceptible to the deleterious effects of ammonium in childhood than in adulthood. Hyperammonemia provokes irreversible damage to the developing central nervous system: cortical atrophy, ventricular enlargement and ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Ambient temperature carbon nanotube ammonia sensor on CMOS platform [PDF]

open access: yes, 2014
We report here the development of a resistive single wall carbon nanotubes (SWCNTs) sensor, based on a CMOS substrate that responds at ambient temperature to ppm levels of ammonia.
