The in vivo potential-regulated protective protein of nitrogenase in azotobacter vinelandii supports aerobic bioelectrochemical dinitrogen reduction in vitro
(American Chemical Society, 2017-06-08)
Nitrogenase, the only enzyme known to be able to reduce dinitrogen (N-2) to ammonia (NH3), is irreversibly damaged upon exposure to molecular oxygen (O-2). Several microbes, however, are able to grow aerobically and ...
Application of ball milling for highly selective mechanochemical polymorph transformations
(American Chemical Society, 2018-06-07)
Milling is an important secondary processing technique in the manufacture of pharmaceuticals, primarily used as a particle size reduction process. p-Aminobenzoic acid (PABA), m-aminobenzoic acid (MABA), o-aminobenzoic acid ...
Investigation of the formation of drug-drug cocrystals and coamorphous systems of the antidiabetic drug gliclazide
(Elsevier, 2019-02-23)
The antidiabetic drug gliclazide (GLZ) has a slow absorption rate and a low bioavailability due to its poor solubility. GLZ is often prescribed along with an antihypertensive, as many diabetic patients have coexistent ...
Electro-mechanical response of a 3D nerve bundle model to mechanical loads leading to axonal injury
(Wiley, 2017-11-21)
Traumatic brain injuries and damage are major causes of death and disability. We propose a 3D fully coupled electro-mechanical model of a nerve bundle to investigate the electrophysiological impairments due to trauma at ...
An experimental and modeling study of the ignition of dimethyl carbonate in shock tubes and rapid compression machine
(Elsevier, 2017-11-05)
Ignition delay times of dimethyl carbonate DMC were measured using low- and high-pressure shock tubes and in a rapid compression machine (RCM). In this way, the effect of fuel concentration (0.75% and 1.75%), pressure (2.0, ...
Biological phosphorus removal during high-rate, low-temperature, anaerobic digestion of wastewater
(Frontiers Media, 2016-03-03)
We report, for the first time, extensive biologically mediated phosphate removal from wastewater during high-rate anaerobic digestion (AD). A hybrid sludge bed/fixed-film (packed pumice stone) reactor was employed for ...
Functional responses and adaptation of mesophilic microbial communities to psychrophilic anaerobic digestion
(Oxford University Press, 2015-10-27)
Psychrophilic (<20°C) anaerobic digestion (AD) represents an attractive alternative to mesophilic wastewater treatment. In order to investigate the AD microbiome response to temperature change, with particular emphasis on ...
An experimental and kinetic modeling study of the oxidation of hexane isomers: Developing consistent reaction rate rules for alkanes
(Elsevier, 2019-05-09)
Alkanes are key components in gasoline, jet and diesel fuels and considerably influence the combustion behavior of these fuels because of their wide range of reactivity. An improved understanding of their combustion behavior ...
Experimental assessment of clinical MRI-induced global SAR distributions in head phantoms
(Elsevier, 2019-10-05)
Accurate estimation of SAR is critical to safeguarding vulnerable patients who require an MRI procedure. The increased static field strength and RF duty cycle capabilities in modern MRI scanners mean that systems can easily ...
Continuous culture of Escherichia coli, under selective pressure by a novel antimicrobial complex, does not result in development of resistance
(Nature Research, 2019-02-20)
We attempted to generate de novo resistance to a newly described biocidal complex, ITC (iodo-thiocyanate complex), and to levofloxacin (LVX) in Escherichia coli ATCC 25922, by means of selective chemostat culture. We ...
