The first peak is associated with the combustion of volatile material, released in the degradation process, the second is caused by the glowing combustion of the carbonaceous residue, and the final exotherm is probably due to the combustion of product gases. The thermogravimetric analysis (TG) ...

At this temperature, organic substances can decompose and give rise to gases and vapors. The time taken to reach the maximum reaction rate (TMR, or as a symbol tmr ) is of great importance. This is also sometimes called the intervention time because up until this time an intervention (e....
Spectroscopic gas sensing based on nondispersive infrared (NDIR) detection offers highly accurate and real-time measurements of very low concentrations of gases such as ethanol, methane, ammonia, and carbon dioxide (CO2)3. NDIR sensor systems have been successfully commercialized and utilized in a ...
of gases finds its application in the detection of cancer cells. The gas sensor employs a mesh type poly silicon micro-hotplate structure. The sensor uses a very thin film made of conducting material that detects the Volatile Organic Compounds (VOCs) liberated by the cancer cells. Some of ...
Seaweed-based films have great potential for preserving freshness in products. These films create a protective barrier that prevents the exchange of gases and moisture between the packaged produce and its conditions. Altering the atmosphere of fresh fruit packaging effectively slows down the process of...
In this paper, we apply our theory to 20 polymer melts and a blend melt, and discuss the quantitative validity of our theory for application to any polymer or blend melt. We estimate the coefficient of thermal expansion of the polymers using the same definition in our previous paper.1 We ...
Another benefit of this energy source is its high per- formance in capturing greenhouse gases (CO2), easy adapta- bility, rapid growth in different water bodies (i.e., wastewater, freshwater, and seawater), and high photosynthetic efficiency (Choi et al. 2019; Aron et al. 2020)....
The main aim of Dekhil et al., (2020) research was to investigate thermal behaviour of three configurations of heat exchangers for sensible thermal energy storage. One of the heat exchangers is commonly used in the agri-food industry and was used in this study as the reference against which...
Thermal Stability Drives Optical Performance Properties such as refractive index, coefficient of thermal expansion (CTE) and light transmission are all important to consider to ensure that materials deliver optimal value in lighting applications. Additional properties, such...
