“…The CO 2 sensing techniques are mainly based on infrared (IR) absorptiometry [48], solid state electrochemical sensor device [49] and optical sensors [15]. Optical carbon dioxide sensors based on fluorescence intensity [15] or absorption changes [50] of pH indicators have several attractive features, including electrical isolation, reduced noise interference, possible miniaturization, and remote sensing.…”

Oxygen and carbon dioxide sensors are involved in many chemical and biochemical reactions. Consequently, considerable efforts over years have been devoted to discover and improve suitable techniques for measuring gas concentrations by optical fiber sensors. Optical gas sensors consist of a gas-sensitive dye entrapped in a matrix with a high permeability to gas. With such sensors, gas concentration is evaluated based upon the reduction in luminescence intensity caused by gas quenching of the emitting state. However, the luminescence quenching effect of oxygen is highly sensitive to temperature. Thus, a simple, low-cost plastic optical fiber sensor for dual sensing of temperature and oxygen is presented. Also, a modified Stern-Volmer model is introduced to compensate for the temperature drift while the temperature is obtained by above dual sensor. Recently, we presented highly-sensitive oxygen and dissolved oxygen sensors comprising an optical fiber coated at one end with platinum (II) meso-tetrakis(pentafluorophenyl)porphyrin (PtTFPP) and PtTFPP entrapped core-shell silica nanoparticles embedded in an n-octyltriethoxysilane(Octyl-triEOS)/tetraethylorthosilane (TEOS) composite xerogel. Also, two-dimensional gas measurement for the distribution of chemical parameters in non-homogeneous samples is developed and is of interest in medical and biological researches.

“…CO 2 sensing properties can be upgraded with auxiliary phases in sensing electrodes, which are binary carbonate systems such as Na 2 CO 3 -BaCO 3 , Na 2 CO 3 -CaCO 3 , Li 2 CO 3 -BaCO 3 , and Li 2 CO 3 -CaCO 3 . The binary systems bring about several advantages such as better long-term stability, quick response time, and resistance to water vapor interruption [18,40,[51][52][53][54]. The device improved in this way has much increased feasibility in practice [55].…”

Structural, elastic, electronic and magnetic properties of the cubic perovskites SmMO 3 (M = V, Fe and Co) are investigated by using the density functional theory. The exchange correlation potential of GGA?U is employed in the present calculations to treat the f-state electrons of Sm atom properly. The structural parameters of these compounds are also evaluated by analytical techniques. The computed structural parameters by both GGA and analytical model are in good agreement with the experimental results. Furthermore, the calculated tolerance factors confirm the theoretically observed cubic structure for all the three compounds. The evaluated critical radii of the compounds provide information about the oxygen migration energy and ion conductivity. The compounds are elastically stable and ductile in nature. The spin-polarized band structures show that the compounds are metallic. The total and partial densities of states show that the compounds are ferromagnetic metals. The calculated magnetic moments of these compounds also reveal that they are ferromagnets.
