Abstract The sensing of CO₂ at room temperature enables the prospects towards low power and low cost CO₂ gas sensors and has a high demand in both industrial and domestic applications. In this work we report detailed work function read out (Kelvin probe) based analysis on copper oxide nanoparticles (CuO NPs) as a new CO₂ gas sensitive.

The major scopes of agri-food based nanotechnology research is towards develop of functional food, effecient and rapid delivery of drugs, nutrients and gene functions at cellular level in plants and animals during stress (Nair et al. ), nano array based technology for detection and contamination of foods by pathogen (Senturk et al. In this work, the NIR acceptor was added to state-of-the art PBDB-T-2F:IT-4F-based solar cells as a third component, leading to: (i) an efficiency increase of the ternary devices compared to the binary solar cells in the presence of the highly-crystalline COi8DFIC acceptor and (ii) much improved photostability under 1-sun illumination.

Porphyrins solution, porphyrin-based nanocomposites and porphyrin Langmuir-Blodgett films porphyrins in membranes as sensors for metal ions, gas, explosives, amine, acid, DNA and others has been. An optical gas sensor device based on tetra-substituted porphyrin dye entrapped in sol–gel glass displays greatly improved signal strength (% at K) on exposure to ppm nitrogen.

The color and shape of the crystals of all the three MOFs are the same (Figure 1).Crystal data with refinement parameters are summarized in Table -crystal X-ray diffraction analysis reveals that 1 crystallizes in the tetragonal space group I4 1 /acd as shown in Figure asymmetric unit of 1 contains one Cu ion, one chloride ion, and one 4,4′-dipyridyl by: 3.

Ina porphyrin-based quartz microbalance provided the first evidence that lung cancer can be diagnosed measuring breath with an array of solid-state gas sensors. () The finding was confirmed and extended in several successive papers and using different sensor technologies; () among these, porphyrin-based colorimetric sensors were Cited by: Array sensors based on organic films or hybrid polymers containing Tb(II) or Sm(II) complexes motifs can also be used due to changes in fluorescence when they are in contact with explosive vapors, reaching limits of detection of ppb (Pablos et al., a, Pablos et al., b, Pablos et al., c, Pablos et al., d, Pablos et al., e Author: Ana M.
