Dataset Information

Thermal and optical behavior dataset of surfaces coated with high reflectance and common materials under different conditions, used in Brazil.

ABSTRACT: External and internal surface temperatures values of coated steel plates and the interior air temperature of a box-like model were collected throughout the time under different conditions: an artificial infrared radiation source was placed facing the external side of the plate to promote the temperature change, the energy power was variated by changing the distance from the plate and simultaneously different airflow conditions were inputted, data was collected by making experiments using the combination of distance and airflow changes. Reflectance raw data, of the materials, was also acquired by measuring the reflectance index of the samples according to ASTM E903 "Standard Test Method for Solar Absorptance, Reflectance, and Transmittance of Materials Using Integrating Spheres". Amplified optical images and infrared images of the samples were taken (using a "Flir e4" infrared camera) while they were under the influence of the source in the three chosen distances (60?cm, 40?cm and 20?cm). Considering that researches at this particular field lack of more direct comparisons of temperature, reflectance and heat flux behaviours; between special high reflectance coatings and common ones when the substrate is steel, when the direction of airflow is changed and when the source is an infrared one; measurements intending to give faster insights and directions were done. These insights can be used by anyone who intends to develop new coating materials and compare them with already existing ones to streamline their researches in this area. Finally, the buying costs of these coatings, similar to commercially used ones, are showed.

Project description:Bacteria repellent surfaces and antibody-based coatings for bacterial assays have shown a growing demand in the field of biosensors, and have crucial importance in the design of biomedical devices. However, in-depth investigations and comparisons of possible solutions are still missing. The optical waveguide lightmode spectroscopy (OWLS) technique offers label-free, non-invasive, in situ characterization of protein and bacterial adsorption. Moreover, it has excellent flexibility for testing various surface coatings. Here, we describe an OWLS-based method supporting the development of bacteria repellent surfaces and characterize the layer structures and affinities of different antibody-based coatings for bacterial assays. In order to test nonspecific binding blocking agents against bacteria, OWLS chips were coated with bovine serum albumin (BSA), I-block, PAcrAM-g-(PMOXA, NH2, Si), (PAcrAM-P) and PLL-g-PEG (PP) (with different coating temperatures), and subsequent Escherichia coli adhesion was monitored. We found that the best performing blocking agents could inhibit bacterial adhesion from samples with bacteria concentrations of up to 107 cells/mL. Various immobilization methods were applied to graft a wide range of selected antibodies onto the biosensor's surface. Simple physisorption, Mix&Go (AnteoBind) (MG) films, covalently immobilized protein A and avidin-biotin based surface chemistries were all fabricated and tested. The surface adsorbed mass densities of deposited antibodies were determined, and the biosensor;s kinetic data were evaluated to divine the possible orientations of the bacteria-capturing antibodies and determine the rate constants and footprints of the binding events. The development of affinity layers was supported by enzyme-linked immunosorbent assay (ELISA) measurements in order to test the bacteria binding capabilities of the antibodies. The best performance in the biosensor measurements was achieved by employing a polyclonal antibody in combination with protein A-based immobilization and PAcrAM-P blocking of nonspecific binding. Using this setting, a surface sensitivity of 70 cells/mm2 was demonstrated.
