Abstract Much effort was taken to elucidate how organic precursors appeared in early Earth, and attention paid two impact experiments: hypervelocity impacts by a propellant gun which simulated meteorite collides Earth forming fatty acids amino from inorganics, micro-impacts planetary ball-mill formed ammonium acetic acid inorganics. Our extended study on showed the formation of carboxylic acids...

We analyse a PDE system modelling poromechanical processes (formulated in mixed form using the solid deformation, fluid pressure, and total pressure) interacting with diffusing reacting solutes medium. investigate well-posedness of nonlinear set equations fixed-point theory, Fredholm's alternative, priori estimates, compactness arguments. also propose finite element method rigorously demonstrat...

Enzymes are tremendously proficient catalysts, which can be used as extracellular catalysts for a whole host of processes, from chemical synthesis to the generation of novel biofuels. For them to be more amenable to the needs of biotechnology, however, it is often necessary to be able to manipulate their physico-chemical properties in an efficient and streamlined manner, and, ideally, to be abl...

Load during mastication is an important factor for the development and maintenance of mechano- receptor properties. The purpose of this study was to examine property changes in the rat TMJ mechano-receptors under conditions of liquid diet feeding and low articular load during the growth period. The hypothesis was that alterations in mastication of liquid diet might increase TMJ mechano-receptor...

Intriguing low frictional properties of 2D materials can be harnessed for thin-film lubrication in small-scale devices by making their mechano-adaptive coatings. Herein, the reduced graphene oxide-polystyrene (rGO-PS) nanocomposite synthesized single-step chemical processing oxide and polystyrene is applied to prepare self-lubricating thin film over silicon substrate. The non-covalent π-π inter...
