Arrhenius equation stated that reaction will proceed faster at higher temperature and with lower activation energy (Ea). Many literatures reported that preexponential factor (A) is constant for certain reaction and there is no relation between A and Ea. E... see more

A set of key parameters and information flows has been formed to simulate stages of probing the outside surface of underground metal pipelines (UMP) taking into account pH of the soil contacting with the pipe metal.Specimens of 17G1S steel placed in acid,... see more

Visible range photon signals emitted after applying five concentrations of hydrogen peroxide (H2O2) on both sides of the left hand were measured and called response signals. Their quantum nature was ascertained in two analyses. The first analysis determin... see more

I have investigated the structural and dynamic properties of water by performing a series of molecular dynamic simulations in the range of temperatures from 213 K to 360 K, using the Simple Point Charge-Extended (SPC/E) model. I performed isobaric-isother... see more

In order to adopt water electrolyzers as a main hydrogen production system, it is critical to develop inexpensive and earth-abundant catalysts. Currently, both half-reactions in water splitting depend heavily on noble metal catalysts. This review discusse... see more

To investigate the combustion characteristics in multi-point lean direct injection (LDI) combustors with hydrogen/air, two swirl–venturi 2 × 2 array four-point LDI combustors were designed. The four-point LDI combustor consists of injector assembly, swirl... see more

1. It was proved, that for cleaning surface waters at water supplying stations there are used stale traditional technologies, so potable waters may continuously contain chloroform (in concentrations  1,8 MPC -  4,7 MPC), periodically dibrom... see more

It was determined that 57 % of samples of potable water from points of bottling and bottled water after the direct installation of equipment or after their long production didn’t meet the hygienic requirements. Every second sample of potable water after a... see more
