“…Contemporary investigations are focused now on detailed study of membrane systems simulating the basic physical and chemical properties of artificial and natural membranes, including their selectivity to various chemicals predominantly in ionic form. In present paper the theoretical bases for the development of such sensors with chemo-sensitive surface is suggested in continuation of our previous publications [4], [5].…”

“…We suppose that the works of research groups which studied the properties of the glass and other surfaces contacting with water solutions and gases may be selected as such theoretical base [6]. According to our modification of such ideas [4], [5], developed primarily by B. P. Nikolsky [6], the surface of detecting element (detector) can be covered with detecting material (glass covering, or film, or membrane etc.) being in contact with water solution with dissolved chemicals (or in some cases with gas phase if water was dropped inside).…”

Nature protections from large-scale fires in different countries of contemporary world become critically necessary and the development of novel electronic information systems with detectors of substances emanated during fires become an urgent problem. Progress of such detectors recording the presence of chemical substances -environmental pollutants becoming now an important task, and the article proposes the theoretical bases for its solution. Such detectors have to contain sensory elements with chemo-sensitive membranes, coatings and/or layers of specific substances. Being in contact with chemicals, such detectors have to demonstrate chemo-sensitivity and, preferably, ability for preliminary identification of these substances. Conducted studies were focused on further development of devices for the detection of various environmental pollutants as well as combustion products. This publication can form the theoretical basis for the development of artificial detectors with chemo-sensitive surfaces. The purpose of present work was to form the theoretical basis for the development of devices for the detection of some harmful chemical substances in environment, including ones emanated during fires and other emergencies, in particular, during accidents at enterprises of oil and gas cycle, chemical enterprises, other industries.

“…As theoretical basis we had chosen phenomena of physicochemical interaction of different ions in solutions with glass surfaces. Extremely high specificity of membranes made of glasses of a certain composition with respect to H + ions is known from previous publications [14], [15], [19], [20]. Changes in glasses' composition leaded to significant changes in the ion selectivity of membrane glass electrodes, determined under the stationary conditions, as well as changes in the kinetic parameters of such selective membranes [14], [19], [20].…”

“…In some cases it was possible to register the changes in the potential of the glass electrode with the changes of ionic composition of the solutions that could be attributed to the variability of the cation specificity constants. Besides of this, the cationic selectivity of glass electrodes, which was determined under the steadystate conditions, depends on what solutions were prepared previously (or stored) examined glass electrodes [14], [15], [20].…”

Ecological monitoring is a real need in contemporary world with its growing tendency of environmental industrial pollution. Among such pollutants there are chemicals emanated in fires, explosions and other emergencies, in process of ruining of chemical enterprises, enterprises of oil and gas cycle, and etc. Some information systems for appropriate monitoring were described briefly in this article together with incorporated hybrid system of electronic chemical pollution detectors that were able to input information to such systems. In previous works of the authors the necessity of development of two types of such detectors with specified properties were substantiated: biosensors and detectors with elements – artificially elaborated selective membranes. This article describes the second type of detectors. The proposed detectors were able to detect harmful chemicals in the environment in the air and water phases; development of such devices was based on the theory of membrane systems. The detectors contained sensor elements covered with chemo-sensitive specific coatings – layers of substances: membranes, films, etc. When in contact with certain chemicals, these detectors demonstrate the properties of chemo-sensitivity and primary identification of such compounds. These studies were aimed on developing detectors of various environmental pollutants based on the theory that can be used as a basis for the detection of such substances. The works were based on a deep study of membrane systems with further development of physical and mathematical models of some substances detection taking into account basic chemical and physical properties of artificial and natural membranes, as well as their ionic selectivity. Some results of mathematical modeling of such detectors with artificial membranes – chemo-sensitive surfaces – were described in the article. Summarizing the previous experience, a brief review of authors’ publications in these items was done, as well as the works of some other authors. The purpose of the work was, basing on profound studying of artificial membrane systems, to suggest them as physical model and summarize the experience of development of their mathematical models.

Introduction. This paper is an overview of the use of standard equipment capable of spraying disinfectants and powders and fi ghting viral infections during a pandemic.Aims and objectives. The objective of the paper is to substantiate the need to develop a new method of combined disinfection. The following problems are to be tackled to meet this challenge: 1) the study of shock waves and their effi ciency if applied to microorganisms; 2) the substantiation of the effi cient use of the available fi re-fi ghting machinery, standard charges and sample equipment for shock-wave disinfection; 3) the search for the optimal and effective cycle of large-scale disinfection; 4) the compatibility substantiation of the shock-wave mode of large-scale spraying of chemical disinfectants; 5) the development and adjustment of impulse fi re-fi ghting equipment to ensure fl exible disinfection control in a wide range of areas.Materials and methods. The weaknesses of disinfection by spraying disinfectants and the impossibility of their elimination by upgrading traditional hydraulic and pneumatic equipment, without changing their operating principles, have been demonstrated.Results and discussion. A new disinfection method, based on the accumulated experience of operation of impulse fi re equipment, is proposed. A disinfection methodology that contemplates the shock-wave destruction of microorganisms has a strong potential. The optimal cycle of spraying disinfectant chemical solutions (DCS) and powders has been substantiated; it assures comprehensive disinfection based on various mechanisms of action: 1) impact compression and prompt heating; 2) pressure relief that destroys microorganisms; 3) convection heating using a squall front that has high-temperature steam whirls; 4) chemical disinfection using micro-drops and DCS vapors sprayed on various surfaces that have irregularities, slots, cracks, irregular shape items.Conclusions. The proposed advanced equipment has no close substitutes in the world. It is protected by the Russian, Ukrainian and Chinese patents. Its production is expedient if launched at defense plants in operation if suffi cient funding is available.
