Different acetonitrile degraders and degrading genes between anaerobic ammoniumoxidation and sequencing batch reactor as revealed by stable isotope probing and magnetic-nanoparticle mediated isolation

Microbial degraders play crucial roles in wastewater treatment processes, but their use is limited as most microbes are yet unculturable. Stable isotope probing (SIP) is a cultivation-independent technique identifying functional-yet-uncultivable microbes in ambient environment, but is unsatisfactory for substrates with low assimilation rate owing to the low isotope incorporation into DNA. In this study, we used acetonitrile as the target low-assimilation chemical in many wastewater treatment plants and attempted to identify the active acetonitrile degraders in the activated sludge, via DNA- SIP and magnetic- nanoparticle mediated isolation (MMI) which is another cultivation- independent approach without the requirement of substrate labeling. The two approaches identified different active acetonitrile degraders in a 3-day short-term anaerobic ammonium oxidation (ANAMMOX). MMI enriched significantly more acetonitrile-degraders than SIP, showing the advantages in identifying the active degraders for low-assimilation substrates. Sequencing batch reactor (SBR, 30-day degradation) helped in more incorporation of N-15-labeled acetonitrile into the active degraders, thus the same acetonitrile-degraders and acetonitrile- degrading genes were identified by SIP and MMI. Different acetonitrile degraders between ANAMMOX and SBR were attributed to the distinct hydrological conditions. Our study for the first time explored the succession of acetonitrile-degraders in wastewater and identified the active acetonitrile-degraders which could be further enriched for enhancing acetonitrile degradation performance. These findings provide new insights into the acetonitrile metabolic process in wastewater treatment plants and offer suggestive conclusions for selecting appropriate treatment strategy in wastewater management.

Experimental study on the influence of locked-in stress on the uniaxial compressive strength and elastic modulus of rocks

The rock contains many inclusions which produce high locked-in stress under the ground stress. In order to study the influence of locked-in stress on the mechanical properties of rocks, the rock-like materials and nitrile rubber particles are used to make a test block of the rock-like model which contains inclusions. The rubber particles will expand as the test block is heated, which creates locked-in stress in the inclusions. Uniaxial compression tests of similar model blocks with different locked-in stresses and different inclusion contents were performed by using a water bath and MTS-5T uniaxial compression testing machine. The results show that the peak strength and elastic modulus decreased with the increasement of locked-in stress and inclusion content. In the meantime, the relationship among the peak strength, the elastic modulus of the test piece, the locked-in stress and the inclusion content were obtained with the help of a mathematical fitting analysis of the quantitative formula. Furthermore, the expression and value curve of the joint impact factor are calculated. This paper evaluates the importance of the locked-in stress in the mechanical properties of the rock-like material and provide a guide for other researchers to further investigate the locked-in stress in rocks.

Design and properties of polyarylene ether nitrile copolymers with improved elongation at break

Polyarylene ether nitrile (PEN) based on biphenol exhibits a high glass transition temperature of 216 degrees C, a high tensile strength of 110 MPa, and low elongation at break of approximately 4%. A series of PEN random copolymers with improved elongation at break were synthesized using various bisphenol compounds and 2,6-dichlorobenzonitrile (DCBN). The resulting PEN random copolymers exhibited a high glass transition temperature and thermal stability up to 513 degrees C in a nitrogen atmosphere. PEN copolymers were amorphous and could easily be cast into transparent films with a tensile strength of 97.93-117.88 MPa and tensile modulus of 2187.98-2558.44 MPa. Most importantly, elongation at break of these PEN copolymers was higher than 13%. PEN copolymer films had a dielectric constant of 3.77-3.89 at 1 kHz and extremely low dielectric loss (<0.02). At the same time, the breakdown strength of PEN was in the range of 137.92-198.19 kV/mm and energy storage density was in the range of 0.32-0.68 J/cm(3). Excellent mechanical, thermal, and dielectric properties of PEN make it possible to use them as high-temperature resistant dielectrics to act on high-temperature resistant insulated cables.

Azanitrile Inhibitors of the SmCB1 Protease Target Are Lethal to Schistosoma mansoni: Structural and Mechanistic Insights into Chemotype Reactivity

Azapeptide nitrites are postulated to reversibly covalently react with the active-site cysteine residue of cysteine proteases and form isothiosemicarbazide adducts. We investigated the interaction of azadipeptide nitrites with the cathepsin B1 drug target (SmCB1) from Schistosoma mansoni, a pathogen that causes the global neglected disease schistosomiasis. Azadipeptide ranitr nitriles were superior inhibitors of SmCB1 over their parent carba analogs. We determined the crystal structure of SmCB1 in complex with an azadipeptide nitrite and analyzed the reaction mechanism using quantum chemical calculations. The data demonstrate that azadipeptide nitrites, in contrast to their carba counterparts, undergo a change from E- to Z-configuration upon binding, which gives rise to a highly favorable energy profile of noncovalent and covalent complex formation. Finally, azadipeptide nitrites were considerably more lethal than their carba analogs against the schistosome pathogen in culture, supporting the further development of this chemotype as a treatment for schistosomiasis.

A preparation method of porous surface nitrile butadiene rubber with low friction coefficient under water lubrication condition by salt leaching

Nitrile butadiene rubber is widely used in water-lubricated bearings due to its excellent performance. Generally, the friction coefficient of water-lubricated rubber bearings typically between 0.05 and 0.18. In this study, a new method for preparing nitrile butadiene rubber with micro-holes surface is developed by porous leaching with salt as pore forming agent. The possibility of using porous surface to minimize friction and wear of rubber materials is researched. The influence of structural parameters, including the hole density and size (which are determined by salt mass fraction of rubber compounds and salt grain-sized, respectively) on tribology performances are also evaluated. In a ring-on-block test, the optimal parameters of modified rubber achieved a low friction coefficient of 0.008, which reduced by 42% compared with untreated one (0.019) under the same operating condition. It can be expected that the developed method is beneficial to reduce the friction coefficient of rubber-steel friction pair under water lubricated condition.

Synthesis of a Molybdenum Hydrido(hydrogermylene) Complex and Its Conversion to a Germylyne Complex: Another Route through Dehydrogenation with Nitriles

A molybdenum germylene complex having Mo-H and Ge-H bonds, Cp*(CO)(2)(H)Mo=Ge(H){C(SiMe3)(3)} (1), was synthesized by the reaction of a methyl molybdenum complex with a trihydrogermane and was converted to a germylyne complex, Cp*(CO)(2) Mo Ge{C(SiMe3)(3)} (2), via dehydrogenation with aryl isocyanates under mild heating. A similar conversion from the same germylene complex into the germylyne complex also occurred using nitriles instead of isocyanates, while releasing imines via a Mo-Ge-N three-membered ring complex Cp*(CO)(2)Mo[kappa(2)(N,Ge)Ge-(N=CHR){C(SiMe3)(3)}] (4, R = Me and aryl groups) as an intermediate. Formation of imines was confirmed by a trapping experiment with BPh3, which afforded a BPh3-imine adduct. In the case of aryl nitriles, the corresponding three-membered ring intermediates were converted into the germylyne complex efficiently by blue LED light irradiation. TD-DFT calculations on the three-membered-ring intermediate suggest that the role of the LED light is to induce CO ligand dissociation from the intermediate via a metal-to-ligand-charge-transfer (MLCT) transition.
