This study aims to create a fire protection design in the kitchen with technology that is easily applied along inexpensive extinguishing media using silica gel from rice husk ash. By an experimental method, active of area uses compartmentalization equipped gas stove, equipment, as well specially designed equipment components. The composition air compartment calculated based on volume so it can ...

The paper presents the results of a detailed study process and products combustion during self-propagating high-temperature synthesis (SHS) ZnO zinc oxide powder from mixtures such common reagents as oxidizer nitrate reducing agent (fuel) glycine, well application synthesized highly dispersed submicron nanosized for phenol photocatalytic decomposition under action ultraviolet irradiation. An aq...

Investigating active, stable, and low-cost materials for the oxygen reduction reaction is one of the key challenges in fuel-cell research. In this work, we describe the formation of N-doped carbon shell coated Co@CoO nanoparticles supported on Vulcan XC-72 carbon materials (Co@CoO@N-C/C) based on a simple supramolecular gel-assisted method. The double-shelled Co@CoO@N-C/C core-shell nanoparticl...

The relationship between the diversity of mixed-species microbial consortia and their electrogenic potential in the anodes of microbial fuel cells was examined using different diversity measures as predictors. Identical microbial fuel cells were sampled at multiple time-points. Biofilm and suspension communities were analysed by denaturing gradient gel electrophoresis to calculate the number an...

Hybrid rocket engine (HRE) performance is dependent on fuel/oxidizer selection and fuel grain geometry. A literature review was performed to identify key trends findings related the application of additive manufacturing (AM) systems for HREs. The effects complex combustion port geometries, embedded structures, end-burning systems, along with use metallic additives, turbulators, diaphragms, gel-...

A model was developed to research the critical conditions and time characteristics of ignition gel fuels in course conductive, convective, radiant mixed heat transfer. MATLAB used for numerical modeling. Original code established pursuant mathematical model. For fuel at initial temperatures corresponding cryogenic storage with different heating schemes, a analysis interconnected processes mass ...

Frontispiece: In article number 2000776, Andriy Horechyy, Iryna Yevchuk, Andreas Fery, and co-workers present a series of hybrid proton conducting membranes composed covalently cross-linked interpenetrating polymeric silica networks. The effects monomer composition, sol–gel composition fraction on performance are investigated discussed. These novel hold promise for the application in direct met...
