Low myo-inositol and high glutamine levels in brain are associated with neuropsychological deterioration after induced hyperammonemia [PDF]

open access: yes, 2004
The neuropsychological effect of hyperammonemia is variable. This study tests the hypothesis that the effect of ammonia on the neuropsychological function in patients with cirrhosis is determined by the ability of the brain to buffer ammonia-induced ...

Supraparticles Composed of Graphitic Carbon Nitride Nanoparticles and Silica‐Supported Horseradish Peroxidase as Customizable Hybrid Catalysts for Photo‐Biocatalytic Cascade Reactions in Continuous Flow

open access: yesAdvanced Functional Materials, EarlyView.
Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

The environmental risk prediction for Odessa city in the case of ammonia emissions from Odessa Port Plant

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2015
In this paper, we consider the environmental risk prediction for Odessa's citizens in the case of ammonia emissions from Odessa Port Plant. The potential risk of ammonia emission can be calculated by multiplying the probability of an accident and the ...

Strong Limit on a Variable Proton-to-Electron Mass Ratio from Molecules in the Distant Universe [PDF]

open access: yes, 2008
The Standard Model of particle physics assumes that the so-called fundamental constants are universal and unchanging. Absorption lines arising in molecular clouds along quasar sightlines offer a precise test for variations in the proton-to-electron mass ...

The ammonolysis of esters in liquid ammonia [PDF]

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 ...

Bipolar Hydrogen Production by Hybrid Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
This review focuses on the recent advances in uniqueness bipolar H2 production from the oxidation of representative small molecules, including 5‐hydroxymethylfurfural, formaldehyde, alcohols, and N‐heterocycle amides. The target electrocatalysts and the underlying mechanisms are discussed in respect to specific substrate oxidation.

Durable Physically Mixed Microporous and Mesoporous MOFs/Nanofiber Aerogel 3D Composites for Effective Toxic Gas Capture and Organophosphonate Detoxification

open access: yesAdvanced Functional Materials, EarlyView.
Ultralight 3D nanofibrous aerogels embedded with metal‐organic frameworks effectively capture and neutralize toxic gases and organophosphonates. Incorporating mesoporous UiO‐66‐NH2 and HKUST‐1 into PAN/PVP fibers enables high MOF loading while maintaining mechanical strength and structural stability.

The effect of brine mass rate on circumferential and longitudinal stress in vertical type separator design

open access: yesCogent Engineering, 2019
The geothermal power plant is converting steam to electricity. The evaporation process in the evaporator produces wet steam (brine). The Brine has a high temperature and contains water, which is quite dominating.
