We report evidence of photon emission in three experiments with hydrogen loading of Ni slabs, during the degassing phase, when hydrogen was introduced into the cell, and during thermal cycling. In the first experiment we obtained excess power of about 20 W, while in the second experiment photon emission was observed instead of power production. In the third experiment, a Ni sample in hydrogen u...

Thermal cycling tests are carried out under a temperature gradient using specimens of thermal barrier coating (TBC). Vertical cracks in the topcoat grow direction thickness, and transverse topcoat, which can lead to delamination, vicinity interface with bondcoat. At 1223 K at substrate surface, heat flux 1.39 MW/m2, remarkable growth is observed, whereas slower lower temperatures conditions. Th...

Use of the polymerase chain reaction, coupled with flow cytometry, to detect a plasmid encoded xylE gene sequence in intact cells of Escherichia coli and Pseudomonas putida was investigated. Optimal incorporation of fluorescently labelled dUTP into a full length PCR product required substitution at a level of 2:3 dUTP:dTTP. Formaldehyde fixed cells of both species were counted before and after ...

The polymerase chain reaction (PCR) has been an essential tool for diagnosis of infectious diseases, but conventional PCR still has some limitations with respect to applications to point-of-care (POC) diagnostic systems that require rapid detection and miniaturization. Here we report a light-based PCR method, termed as photo-PCR, which enables rapid detection of bacteria in a single step. In th...

Polyvinyl alcohol (PVA) is a hydrophilic polymer with various characteristics desired for biomedical applications and can be transformed into a solid hydrogel by physical crosslinking, using a low-temperature thermal cycling process. As with most polymeric materials, the mechanical properties of the resultant PVA are isotropic, as oppose to most soft tissues, which are anisotropic. The objectiv...

This paper examined the adhesive strength of paint-on resin to crown and bridge composites after soaking in water and thermal-cycling. Three shades of paint-on resin were coated on three kinds of crown and bridge composite under four surface treatment conditions (a combination of sandblaster and pretreatment liquid). These specimens were soaked in water at 37 degrees C for 1 day, 1 month, and 1...

Anisotropic conductive film (ACF) has been used for flip chip interconnection of a silicon based MEMS finger print sensor to a signal processing ASIC. The assembled sensor device was subjected to a short term high temperature profile with peak temperature 260 C simulating subsequent reflow soldering of the device, and to thermal shock cycling from -40 to +85 C. The reliability of interconnect...

RFID solutions will improve the traceability of biological samples stored at low temperature (77K) in biobanks. To achieve this goal, the reliability of RFID tags is essential. In this paper, we focus on the reliability aspect of RFID tags in harsh environment and more specifically to assembly design optimization through numerical simulations and accelerated life tests. A packagedimensioned mod...

The Space Dynamics Laboratory (SDL) has observed, over several years of work with various blackbodies, significant unexplained calibration drifts in some industrial PRTs. With a mandate to build more accurate calibration sources with tens of millikelvin accuracy, SDL began an effort to understand the calibration drifts in small temperature sensors less than an inch long. Testing was performed m...

The influence of monomer content on the viscoelasticity, water sorption and solubility of experimental fluorinated soft lining materials was investigated. Changes in the viscoelastic properties of the materials were also examined after thermal cycling. Four fluorinated soft lining materials containing different amounts of methoxy diethylene glycol methacrylate (MDGMA) and tridecafluorooctyl met...
