Abstract:

The main objective of this project is the investigation of hydrogen influence on gas-phase combustion of hydrocarbons in air, in deflagration regime, by experimental and numerical methods. Under the project, relevant initiation parameters (the quenching distance and the minimum ignition energy) and propagation parameters (normal burning velocity and propagation speed) will be examined, in correlation with the initial composition and pressure of flammable mixtures and with characteristic flame properties (adiabatic flame temperature, total concentration of active radical species).

The study will be realized with LPG (Liquefied Petroleum Gas)-air mixtures with added H2, at various initial LPG concentrations within its flammability limits, hydrogen fractions (5-30 vol%) and initial pressures, within 0.5 and 2.0 bar, at ambient initial temperature. LPG has the typical composition of Romanian blends.

The estimated scientific results delivered by the project consist in the full characterization of LPG-air-H2 mixtures from point of view of flammability parameters, in order to obtain safety operating characteristics for storage, transport and manipulation of such mixtures and to develop increased energetic efficiency with low pollutant emissions.

Abstract:

The main purpose is the monitoring of greenhouse gases which are directly linked with the human activities. To this scope the project will develop a new technology for the fabrication of smart, miniaturized sensor array for greenhouse gases monitoring. A microsensors array based on alumina transducers and MOx (metal oxides) and polymer materials will be developed. The targeted gases considered as main contributors to the greenhouse effect, are methane, ozone, carbon dioxide and water vapors. The microtransducers are made up of alumina µ-chips with interdigitated gold electrodes on top (front side of the transducer) and platinum microheater on the backside. The microsensors array will contain undoped and doped MOx sensitive films (SnO2, ZnO, SnO2-ZnO, CuO) and polymers deposited by safe and low-cost chemical routes (sol-gel and hydrothermal method).

The novelty of the project consists of: a) the significant improvement of properties of the proposed materials by controlling the nanometer-level architecture oxide (nanowires) and by utilizing the multilayered mixed structure containing MOx and polymeric films; b) new technology for microsensors fabrication on thin alumina with very low power consumption. A laboratory platform and a mobile apparatus for gas detection will be tested. In Romania a project focused on monitoring of greenhouse gases, comprising detection, correlated with geographical and environmental conditions, data acquisition and interpretation is new. The two years duration will allow to optimize and to demonstrate the technology up to TRL 4, to fabricate the sensors (TRL 4), to start the data acquisition and interpretation. All these developments will allow a long-term prediction algorithm for pollution evolution, geographical mapping of areas with the highest pollution, prediction of local and global warming, under different RCP scenarios (Representative Concentration Pathways), monitoring of local evolution of these gases.

Project website: https://www.imt.ro/voc-detect

Abstract:

Most human environments are characterised by the presence of a large number of chemical substances which mainly belong to the group of volatile organic compounds (VOC). Numerous studies revealed the toxic and carcinogenic effects of these VOCs which usually can be found in indoor air, but the tools for the detection of VOCs are still not very precise and too expensive.

The project will develop new sensors based on nano MOX and CNT materials for VOC detection, integrated into a smart portable system providing quantitative information about the concentration of Formaldehyde and Benzene in indoor air.

The results will be:

- Technology demonstrator and Smart, portable system prototype and new formaldehyde and benzene sensors;

- Technology for thin sensitive films deposition and integration in the microtechnology steps flow for sensors fabrication on silicon – Demonstration;

- E-Nose system, including sensor array, data processing algorithms and software for VOCs accurate detection.

Abstract:

The aim of the project is the realization of an „electronic nose” for detection of very low concentration of pollutants and explosive gases. To obtain such a device, a microsensor array will be fabricated using integrated and miniaturized silicon based microtransducers. The microtransducers containing a microheater and interdigitated electrodes on top are built on a thin Si3N4 membrane suspended on four arms. The microsensor array will contain metallic-oxide based sensors, namely TiO2, ZnO and HfO2 nanostructured materials with special morphologies, with large surface areas, patterned on top of the interdigitated electrodes. These are one order of magnitude more sensitive than „normal materials” and able to detect very small quantity of gases. The novelty of the project consists: a) the significant improvement of properties of the proposed materials by controlling the nanometer-level architecture oxide (nanostructures) by forming ordered nanoporous structures, nanorods, nanotubes, spheres, and thin films with controlled morphology and porosity; b) new technology for microsensors fabrication with very low power consumption; c) using HfO2 nanotubes obtained by chemical methods for sensor application. The microsensor array based on TiO2, ZnO and HfO2 nanostructured materials will be tested as sensors for 7 gases: H2, CO, propane, NOx, NH3, CH4, H2S. The microsensor arrays will be encapsulated and coupled with an electronic module which will allow interfacing with a computer. A laboratory platform and a mobile apparatus for gas detection will be elaborated and tested especially for interior microclimates. The use of the microsensors together with information technology will improve these microclimates and will reduce their energy consumption.
